  In the first or second ultrafine device, the outer wall of the casing is formed into a cylindrical shape, and is eccentric to the extent that the flow path is formed concentrically within the casing or without contacting the cylindrical walls. The intermediate cylindrical wall and the inner cylindrical wall are separated from each other, the intermediate cylindrical wall is connected to the casing ceiling wall and the casing bottom wall to form an outer annular flow path, the inner cylindrical wall is connected to the casing bottom wall, and By forming a gap with respect to the casing ceiling wall, the intermediate annular channel formed by the intermediate cylindrical wall and the inner cylindrical wall communicates with the inside of the inner cylindrical wall via the gap, and the storage tank Or in the first water introduction part from the sludge concentration tank, the first high speed water stream containing the sludge generated by the high pressure pump is supplied to the air introduction part, where the air is introduced into the first high speed water stream as bubbles, The first high-velocity water flow with the bubbles introduced is Then, it is supplied to the intermediate annular flow path and then suddenly falls into the inside from the upper end of the inner cylindrical wall and collides with the bottom wall of the casing, and is sucked from the inside of the inner cylindrical wall by the high pressure pump and discharged at a high speed.

The cell membrane is destroyed and ultrafine, and the treated water containing the ultrafine sludge is partially extracted from the outer annular channel and guided to the storage tank or the sludge concentration tank.

  The first or second ultra-miniaturization apparatus has a substantially inverted U-shape in an elevational view and is connected to each other at the center upper part in a communication state, and is composed of a curved upper part and a bottomed vertical lower part. Fixed to the bottom of the vertical lower part so as to form an annular space between the plurality of substantially inverted J-shaped outer cylinders to which the discharge pipes for discharging the gas are connected and the vertical lower part of each outer cylindrical body A high-speed fluid containing a solid object to be processed is supplied to an annular space of the bottomed vertical inner cylinder and the plurality of outer cylinders in a clockwise direction in a plan view of 8 m / second or more, or The first high-pressure pump and piping that generate a counterclockwise high-speed swirling flow, and the bottom of the inner cylinder of the outer cylinder to which high-speed fluid is supplied, fall to the bottom beyond the open upper edge of the inner cylinder.

The object to be processed contained in the high-speed fluid is refined to the micron level by the shearing action that generates the high-speed swirling flow in the annular space and the impact force caused by the fluid falling to the bottom of the inner cylinder.

  As an effect of the present invention, in a sewage treatment facility containing human waste and the like, sewage sucked by a high-pressure pump is received at 8 m / min in a storage tank that receives sewage containing human waste and livestock manure and fermented bacteria. Supplying to the annular flow path of the first ultrafine device at a high speed of more than a second, the sewage cluster and contained organic matter will be ultrafinened to the micron level by at least shearing action of the high-speed water flow, and returned to the storage tank. Therefore, ultrafine suspended organic matter is well dispersed between ultrafine water clusters, and suspended organic matter with a very large surface area per unit weight is efficiently converted into carbon dioxide gas and water in an extremely short time by the added fermentative bacteria. It can be fermented and decomposed to greatly increase the treatment capacity of sewage, and it also proliferates while treating fermentative bacteria and suppresses the generation of malodor. Therefore, the conventional first stirring tank, first aeration tank, second stirring tank and second aeration tank can be omitted. In the next sedimentation tank, the supernatant water and sludge are separated from the intermediate sewage treated by the fermenting bacteria of floating organic matter, and the supernatant water is supplied with a flocculant and a pH adjuster in the post-treatment section, so that the coagulation and pH adjustment are performed. Later it is discharged as treated water. As for sludge, fluid sludge supplied in the next sludge concentration tank is sucked by a high-pressure pump and supplied to the annular flow path of the second ultrafine refiner at a high speed of 8 m / second or more to at least shear the high-speed flow. By refining to the micron level by the action and returning it to the sludge concentration tank, the cell membrane of the dead fungi forming the sludge there is destroyed by the ultra-miniaturization, and the fermentative decomposition is carried out by the additional fermentation bacteria using the cytoplasm that is given as nutrients This will greatly reduce the volume of sludge and increase the fermentation bacteria. At the same time, it is separated into supernatant water and precipitated sludge in the sludge concentration tank, and the supernatant water is received in a miscellaneous drainage tank and discharged by aeration treatment or returned to the post-treatment section. It can be eliminated by microbial treatment using a mixture of sawdust and fermenting bacteria, etc., and it can be drastically reduced and eliminated by two stages of sludge treatment. Therefore, a dryer and an incinerator are not required, and initial investment costs and operating costs can be reduced. In addition, the ultra-miniaturization apparatus as the main apparatus has a relatively simple configuration for generating a high-speed swirling flow, and is easy to maintain and maintain. Various harmful fungi in sewage are almost completely killed by micronization to the micron level by the first and second micronizers.

  In front of the storage tank, a receiving tank for receiving an object to be processed such as human waste, livestock excrement and sewage, a drum screen for separating the object to be processed into a filtrate, and a screw press for dewatering the sheath are provided. In addition, sanitary products that are difficult to dissolve in water that impede the operation of the pump that supplies high-speed fluid to the ultrafine device are captured in advance with a drum screen, dehydrated with a screw press, and commissioned to a processing company. be able to.

In addition, the storage tank is partitioned into an upstream part connected to the ultrafine device and a downstream part to which fermentation bacteria are supplied. Performing effective fermentative bacteria treatment by preventing the consumption of fermentative bacteria by the ultra-miniaturization device that also refines fermentative bacteria.
Furthermore, the storage tank is provided with at least two sets each of which the connection to the ultrafine device is switched every predetermined time, and the fermented bacteria are supplied to the storage tank that is disconnected, and the storage tank is connected The supply of fermenting bacteria is stopped, and the fermenting bacteria are prevented from being consumed by the ultra-miniaturization apparatus that also refines the fermenting bacteria.

  Between the storage tank and the settling tank, there are a first denitrification agitation tank, a first nitrification aeration tank, a second denitrification agitation tank for methanol, and a second aeration tank for methanol removal. If the sludge is partly returned from the settling tank to the first stirring tank for denitrification, which is provided so as to be shut off / opened, denitrification by denitrifying bacteria, nitrification by nitrifying bacteria, and denitrification by methanol With the use of nitrogen, the organic matter can be appropriately canceled in a conventional manner, and the parallel processing with the fermenting bacteria and the switching processing to either one can be selected as appropriate.

The post-treatment section includes a mixing tank to which a flocculant such as a sulfuric acid band and a pH adjuster are supplied, a flocculant tank to which a polymer flocculant is supplied, a discharge supernatant water, and sludge to be supplied to the sludge concentration tank. A final settling tank that separates the water into the rivers as treated water that has cleared regulations such as BOD (biological oxygen demand) and COD (chemical oxygen demand) in each region. It can be released.
The biological treatment unit is composed of a pig raising system using fermented bacteria-contained sawdust or a fermented bacteria-contained sawdust / chip continuous stirring device, and can be extinguished by organisms using fermentative bacteria without incinerating the final sludge from the sludge concentration tank.
The miscellaneous drainage tank is connected to the aeration tank or the post-treatment unit, and the collected miscellaneous drainage is supplied to the aeration tank or the post-treatment unit by a pump, and after the aeration process or the aggregation process and the pH adjustment process, It can be released after clearing regulations such as COD. Furthermore, the collected wastewater is also returned to the first receiving tank by a pump.

  The first ultrafine device is formed such that the outer wall of the casing is formed in a cylindrical shape, and the inner cylindrical wall is formed so as to be concentric inside the casing or eccentric so as to form a flow path without contacting the cylindrical walls. If an air gap is provided, an annular flow path is formed between the wall and the inner cylindrical wall, and the high-speed water flow supplied to the wall constantly changes its flow direction to generate a strong centrifugal force, strongly against the outer wall surface. A large compressive force and a shear force are generated between the laminar flow on the wall surface, and at the same time, cavitation is generated by laminar flow separation from the inner wall surface. It can promote destruction and ultra-fine cytoplasm. In the circular annular channel, it is relatively easy to maintain the water flow velocity. Further, by connecting the inner cylindrical wall to the casing bottom wall and forming a gap with respect to the casing ceiling wall, the gap between the annular channel formed by the cylindrical outer wall and the inner cylindrical wall and the inside of the inner cylindrical wall is reduced. The high-speed water flow from the annular channel and at the same time, the water flow supplied from the high-pressure pump falls into the inner cylindrical wall and collides with the bottom wall of the casing to form a cluster of water by impact force. Promotes ultra-fine bubbles. Further, since water is sucked from the inside of the inner cylindrical wall by the high pressure pump, the impact force of the water flow falling into the inside can be made stronger. A second high-speed water flow that is sucked by a high-pressure pump and discharged at a high speed is supplied to the annular channel, thereby forming a circulation channel across the annular channel and the inner cylindrical wall. Therefore, it is possible to repeatedly refine the water cluster during circulation, destroy the cell membrane of sludge bacterial dead bodies in the water stream, and refine the internal cytoplasm. A part of the treated water containing the dead bacteria bacteria of the ultrafine sludge is extracted from the annular channel and supplied to the tank.

  In the first or second ultrafine device, the outer wall of the casing is formed in a cylindrical shape, and is concentrically inside the casing, or eccentric so that the flow path is formed without contacting the cylindrical walls. When the intermediate and inner cylindrical walls are separated, an outer and intermediate annular flow path is formed between the outer, intermediate and inner cylindrical walls. The high-speed water flow supplied to these external and intermediate annular channels constantly changes the flow direction to generate a strong centrifugal force and strongly hits the outer wall surface, causing a large compressive force and a shear force between the laminar flow on the wall surface. At the same time, laminar flow separation is caused from the inner wall surface to generate a cavitation action, and it is possible to promote the ultrafine sludge, that is, the destruction of the cell membrane of the dead bacterial sludge and the ultrafine cytoplasm. In the circular annular channel, it is relatively easy to maintain the water flow velocity. Further, when the intermediate cylindrical wall is connected to the casing ceiling wall and the casing bottom wall, the inner cylindrical wall is connected to the casing bottom wall and a gap is formed with respect to the casing ceiling wall, the water flow supplied to the intermediate annular channel is The water drops suddenly from the top of the wall to the inside, and the impact force generated by crashing into the bottom wall of the casing promotes ultra-fine water clusters and sludge. Bubbles are introduced into the water flow by an ejector action using a first high-speed water flow generated by a high-pressure pump in the air introduction portion of the first water introduction portion in the water introduction portion. Air absorbed in water strongly generates the above cavitation action. The first high-speed water flow into which the bubbles are introduced is supplied to the intermediate annular flow path, and then suddenly falls into the inside from the upper end of the inner cylindrical wall as described above and collides with the casing bottom wall. Since it is sucked by the second high-pressure pump from the inside of the wall, the impact of the water flow falling into the inside can be made stronger. A second high-speed water flow formed by being sucked by the high-pressure pump and discharged at a high speed is supplied to the outer annular channel at the second water introduction part, and further from the outer annular channel to the first high-pressure pump A circulation path is formed by being supplied to the suction side via a pipe line. By repeating the cycle, it is possible to make the cluster ultrafine and sludge ultrafine. The treated water containing ultrafine sludge is partially removed from the outer annular channel and returned to the tank.

  Since the first or second ultra-miniaturization apparatus has a double inverted U-shaped structure as described above, the object to be processed contained in the high-speed fluid is an animal. Even if organic substances are contained, the micron is continuously and efficiently transported in a high-speed flow by the shearing action that generates a high-speed swirling flow in the annular space and the impact force caused by the fluid falling to the bottom of the inner cylinder. Ultra fine to the level of. For example, when a spherical workpiece with a radius of 1 mm is made ultrafine to a radius of 0.1 micron, the surface area per unit weight (specific surface area) is almost 10,000 times larger, and depending on the processing microorganisms and chemicals such as fermentation bacteria It will be treated very efficiently. In addition, when the fluid discharge amount is reduced by the discharge amount adjusting means provided in the fluid discharge pipe from the bottom of the inner cylinder of the outer cylinder other than any of the above, the outer cylinders are arranged in a substantially inverted U shape in the center upper part. In this way, the swiveling direction is reversed so that it does not interfere with the turning direction while turning at a high speed to one of the outer cylinders described above, and the workpiece is repeatedly super-extended to the desired particle size. Subject to miniaturization. The workpiece is subjected to a shearing action between the fluid layer adhering to the inner surface of the outer cylindrical body and the high-speed swirling flow layer adjacent to the fluid layer, and is ultrafine-sized by a drop collision to the bottom of the inner cylindrical body Therefore, by simply increasing the wall thickness, it is possible to provide a device with a simple structure and high durability. On-off valves are arranged in the piping from the first high-pressure pump, the piping to the second high-pressure pump, and the above-mentioned discharge piping, respectively, and the fluid supply amount is adjusted by the on-off valves of the piping from the first high-pressure pump. In addition, the fluid supply can be stopped in the event of an emergency of the device. Also, the suction amount from any one of the inner cylinders can be adjusted so that an optimum high-speed swirling flow is formed in any one of the annular spaces corresponding to the supply fluid by the on-off valve of the pipe to the second high-pressure pump. . Further, when the fluid discharge amount is reduced by the opening / closing valve of the discharge pipe, the fluid can be returned from one of the outer cylinders other than the above to any one of the outer cylinders while being swung at a high speed. In addition, when a predetermined ultra-miniaturization is achieved by the ultra-miniaturization action by the outer cylinder and the inner cylinder other than any of the above and the inner cylinder, it is possible to discharge more than the supply amount from the first high-pressure pump. It is possible to set an open / close valve for the discharge pipe.

  The air introduction part is composed of an ejector that uses high-speed water flow, and without using an air pump, the air is sucked and mixed into the water flow by the negative pressure generated by the high-speed water flow that is ejected from the nozzle of the ejector. Can do. Furthermore, the high-speed water flow supplied into the annular channel defined by the cylindrical wall inside the apparatus casing is supplied from the tangential direction to the annular channel, and the water flow is smoothly supplied into the annular channel, It helps prevent rapid changes in velocity and maintains the above action of high velocity water flow throughout the path. When the cylindrical wall partially has a curvature changing part such as a flat part, the water flow speed slightly decreases at these curvature changing parts, but the shear force acting between the water flow layers can be increased by changing the direction of the water flow.

High-speed turning of 30 to 50m / sec The first high-pressure pump P1 and the pipe 22 composed of a high-pressure submersible pump for generating H1, and the bottom 21A of the inner cylinder 20C of the outer cylinder 20A on the fluid supply side, beyond the open upper edge 21B of the inner cylinder 20C The intermediate treated water W1 falling to the bottom 23A and flowing in is sucked into the annular space 29 of the outer cylindrical body 20B on the fluid discharge side, and the high-speed fluid L2 containing the ultrafine processed organic substance is almost tangentially. Two series of second high-pressure pumps P2, P2 and pipes 22A, 22A for supplying and generating a high-speed swirling flow H2 of 8 m / sec or more in a clockwise direction in a plan view, preferably 30 to 50 m / sec, and a fluid discharge side A pipe 24 for returning treated water W2 falling from the bottom 26A of the inner cylinder 20D of the outer cylinder 20B to the bottom 26 over the open upper edge 27 of the inner cylinder 20D and returning to the tanks 13 and 17; The first high pressure pump 1 is connected to the upper center of the coupling of the open / close valves V1, V2, V3 and the two outer cylindrical bodies 20A, 20B provided in the pipe 22 from the first pipe 22, the pipe 22B to the second high-pressure pump P2, and the discharge pipe 24. , And a surplus fluid discharge pipe 24 </ b> A for returning surplus fluid to the tanks 13 and 17.

  The curved upper part 21 of each outer cylindrical body 20A, 20B is formed of a single curved tube having an inverted U shape. The inner cylindrical body 20C on the fluid supply side has a relatively low height for facilitating inflow into the inside thereof, and the bottom 23A is lowered to increase the head, whereas the inner cylindrical body 20C on the fluid supply side The inner cylindrical body 20D has a height that is convenient for guiding the high-speed swirling flow H2 upward in order to return to the annular space 28 on the fluid supply side when repeated ultra-miniaturization and to increase the head. Is high. In the inner cylindrical body 20C on the fluid supply side, the intermediate treated water W1 is sucked from the bottom 21A by the two second pumps P2 and P2, so that the intermediate treated water W1 exceeding the open upper edge 21B It collides violently with 23A, strengthening the ultrafine refinement of organic matter and water clusters. Further, an ejector E that sucks air A using a high-speed water flow in order to generate a lot of cavitation bubbles in the pipe 22 from the first pump P1 or to activate aerobic bacteria in the tanks 13 and 17. Is provided. Further, inside the outer cylindrical body 20B on the fluid discharge side, there are a plurality of projecting members 29A projecting into the annular space 29 so that the projecting amount can be changed, which is generated by the second pumps P2 and P2. By causing the high-speed swirling flow H2 to collide with the projecting member 29A, cavitation and impact force that easily occur behind the projecting member 29A can be applied to the organic matter in the intermediate treated water. Adjustment of deceleration, cavitation action, and impact force of the high-speed swirling flow H2 is performed by changing the number of protruding members 29A and the protruding amount. The outer cylindrical body 20B and the inner cylindrical body 20D on the fluid discharge side share the bottom 26.

  The ultrafine refinement of the organic matter and water in the intermediate treated water W1 is performed by the water layer in which the high-speed swirling flows H1 and H2 in the annular spaces 28 and 29 are attached to the inner surfaces of the outer cylindrical bodies 20A and 20B and the high-speed swirling water flow layer adjacent thereto. And the cavitation action associated therewith, the impact force generated when the intermediate treated waters W1 and W2 fall on the bottoms 23A and 26 of the inner cylindrical bodies 20C and 20D, and the high-speed swirling flow H2 This is achieved by a collision with the protruding member 28. Depending on the type of organic matter in the water to be treated and the degree of ultrafineness, the operation mode of the double continuous ultrafine refiner 20 can be selected. In other words, if there is no need to repeat ultra-miniaturization in response to organic materials that are easy to miniaturize or loose super-miniaturization, operation can be performed with the supply amount and discharge amount balanced, and repeated ultra-miniaturization , The on-off valve V3 provided in the discharge pipe 24 is throttled so that the discharge amount is smaller than the supply amount of the water to be treated, so that the high-speed swirl flow H2 in the annular space 29 on the fluid discharge side is swirled at high speed. However, the swirling direction is reversed so as not to cause swirling interference with the high-speed swirling flow H1 in the annular space 28 and flows into the annular space 28 on the fluid supply side, and the object to be processed is repeatedly subjected to ultrafine processing to a desired particle size. To drive. In this case, the supply amount is balanced with the discharge amount from the discharge pipe 24 and the discharge amount from the excess fluid discharge pipe 24A. The on-off valve V1 of the pipe 22 from the first pump P1 is used for adjusting the supply amount and stopping the supply in an emergency, and the on-off valves V2 of the pipes 22B up to the second pump P2 are used for the high-speed swirling flow H2. The on-off valve V3 used for speed adjustment and provided in the discharge pipe 24 is used for controlling whether or not ultra-miniaturization is repeatedly performed as described above.

  The two-cylindrical sludge ultrafine refiner 30 has an outer wall 33a of a casing 33 formed in a cylindrical shape, an inner cylindrical wall 34 is provided concentrically inside the casing, and a lower end of the inner cylindrical wall 34 is disposed at the bottom of the casing. The gap C is formed between the cylindrical outer wall 33a and the inner cylindrical wall 34 and the inner 36 of the inner cylindrical wall 34 by connecting the wall 33b and forming the gap C with respect to the casing ceiling wall 33c. It communicates through. Further, the high-speed water flow W1 ′ containing the organic matter supplied by the high-pressure submersible pump inside the tanks 13 and 17 is supplied from the supply part 31 at the center of the casing ceiling wall 33c of the first water introduction part to the inside 36 of the internal cylindrical wall 34. To supply. Next, the present apparatus 30 is configured to provide a second high-speed water flow W2 formed by being sucked from the lower part of the inner cylindrical wall interior 36 by the second pump P2 ′ and discharged at a high speed at the lower part of the casing outer wall 33a. Supplying from the introduction portion 37 to the annular flow path 35 from a substantially tangential direction, and then suddenly dropping from the gap C at the upper end of the internal cylindrical wall 34 into the interior 36 to crash into the casing bottom wall 33b. In the circulation channel formed over the annular channel 35 and the inner cylindrical wall interior 36, the water cluster is made ultrafine by the above-described action, and the sludge and the organic matter in the water flow are made ultrafine, and the ultrafine sludge and the organic matter are obtained. A portion of the treated water W3 containing water is removed from the annular channel at the water discharge portion 39 provided at the upper portion of the casing outer wall 33a and returned to the tanks 13 and 17. The supply unit 31 can be provided with an ejector E that allows air A to flow in.

  Further, the degree of repeatedly passing the water flow W2 ′ through the circulation flow path can be increased by increasing the gap C, reducing the water discharge amount in the water discharge portion 39, or increasing the amount of waste water containing sludge, and combining them. If they can be combined and increased, and the degree of repeated circulation is reduced, the reverse adjustments are made. The casing 33a separates the bottom wall 33b into two stages, but it goes without saying that the bottom wall can be integrated with the lower end level of the internal cylindrical wall 34. It is also possible to provide the inner cylindrical wall 34 in an eccentric manner to such an extent that the flow path 35 without much change in the flow cross section is formed without contacting the cylindrical walls. Furthermore, the casing outer wall 33a and the inner cylindrical wall 34 can partially have a curvature changing portion such as a flat portion, or a vertically long slit can be formed in the inner cylindrical wall 34. It can be configured to increase the shear force.

  Although not shown in the figure, the three-cylinder sludge ultrafine refiner will be described. The outer wall of the casing is formed in a cylindrical shape, and the intermediate cylindrical wall and the inner cylindrical wall are concentrically arranged inside the casing. The upper end of the intermediate cylindrical wall is connected to the casing ceiling wall, the lower end is connected to the casing bottom wall to form an outer annular flow path, the lower end of the inner cylindrical wall is connected to the casing bottom wall, and a gap is formed with respect to the casing ceiling wall. By forming, the intermediate | middle annular flow path formed with the intermediate | middle cylindrical wall and the internal cylindrical wall and the internal cylindrical wall inside are connected via the clearance gap. In addition, the first high-speed water flow generated by sucking sewage containing organic matter and sludge inside the tank by the first high-pressure pump placed near the device is introduced into the first water introduction part of the water introduction part. To the first high-speed water flow, where air is introduced as bubbles into the first high-speed water flow, the high-speed water flow introduced with the bubbles is supplied tangentially to the intermediate annular channel, and then from the upper end of the inner cylindrical wall A second high-speed water stream formed by abruptly falling into the casing and colliding with the bottom wall of the casing, and sucked by the second high-pressure pump from the inside of the inner cylindrical wall and discharged at a high speed is removed at the second introduction part. The annular channel is supplied from the tangential direction. This device further allows the water flow to repeatedly flow in a circulation path formed by connecting the outer annular flow path to the suction side of the first pump via a conduit, and the intermediate annular flow path and the outer Water clusters are refined by shearing action and cavitation action in the annular channel and crushing to the bottom wall of the casing, and sludge and organic matter in the water stream are refined, and the treatment contains ultrafine bubbles. Spent water is partially removed from the outer annular flow path at the water discharge portion and returned to the tank.

  In addition, the degree to which the water flow is circulated repeatedly increases the gap, reduces the water discharge amount in the water discharge portion, increases the water introduction amount in the first water introduction portion, and throttles the valve on the suction side of the first pump. If the pipe valves can be opened wide or combined and increased, and the degree of repeated circulation is reduced, the reverse adjustments are made. The casing separates the bottom wall in two stages, but it goes without saying that the bottom wall can be integrated at the lower end level of the middle and inner cylindrical walls. The middle and inner cylindrical walls can be provided eccentrically so that the flow paths are formed without contacting the cylindrical walls. The casing outer wall and the intermediate and inner cylindrical walls can partially have a curvature changing portion such as a flat portion, or a longitudinal slit can be formed in the intermediate and inner cylindrical walls. It can be configured to increase the shear force.
