Description

  The present invention relates to a purification device that can be used in, for example, a pond.

  Conventionally, many pond purification devices exist, but there are disadvantages that the purification rate is slow and that the effect of pond purification is not clear.

  In general, there is a method of coagulating and precipitating pond water by adding a flocculant, but there is a problem that a large amount of sludge derived from the flocculant is generated, making it difficult to dispose of the generated sludge. .

  In addition, there is a method of simply filtering the pond water, but it is difficult to dispose of a large amount of organic sludge generated by filtration, and no improvement in the water quality of the pond water can be expected by filtration. There was a problem.

  Also, there has been a pond purification device using ozone micro-nano bubbles. However, since the purification device has a low purification capacity, there is a problem that the effect cannot be exerted on a pond that has undergone eutrophication.

  Incidentally, Japanese Patent Application Laid-Open No. 2004-121962 (Patent Document 1) discloses a method and apparatus for using nanobubbles. This method and apparatus make use of characteristics such as a decrease in buoyancy of nanobubbles, an increase in surface area, an increase in surface activity, generation of a local high-pressure field, and a surface-active action and a bactericidal action by realizing electrostatic polarization. More specifically, these properties are related to each other, so that various objects can be washed with high functionality and low environmental load through the adsorption function of dirt components, the high-speed washing function of the object surface, and the sterilization function. Purification can be performed.

  Japanese Patent Laid-Open No. 2003-334548 (Patent Document 2) discloses a method for generating nanobubbles. This generation method includes (1) a step of cracking and gasifying a part of the liquid, (2) a step of applying ultrasonic waves to the liquid, or (3) cracking and gasifying a part of the liquid and It consists of a step of applying sound waves.

  Japanese Patent Laying-Open No. 2004-321959 (Patent Document 3) discloses a waste liquid treatment apparatus using ozone microbubbles. This processing apparatus supplies the microbubble generator with ozone gas generated from the ozone generator and the waste liquid extracted from the lower part of the processing tank via a pressure pump. Moreover, the said processing apparatus ventilates the produced | generated ozone microbubble in the waste liquid in a processing tank from the opening part of a gas blowing pipe.

Patent Documents 1 to 3 do not describe a method for simplifying disposal of organic sludge generated by pond purification or a method for sufficiently purifying pond water that has been eutrophied.

  Hereinafter, the purification apparatus of the present invention will be described in detail with reference to the illustrated embodiments.

(First embodiment)
In FIG. 1, the purification apparatus of 1st Embodiment of this invention is shown typically.

  The said purification apparatus is an apparatus which can purify the water of the pond 1, mineralize the organic sludge which generate | occur | produces by this purification, and can use it effectively as a soil improvement material.

  More specifically, the purification device includes a filter 19, an underwater pump type ozone micro / nano bubble generator 48 as an example of an underwater pump type micro / nano bubble generator, and a swirl type as an example of a swirl type micro / nano bubble generator. An ozone micro / nano bubble generation device 49, an ozone nano bubble generation device 50 as an example of a nano bubble generation device, an organic sludge decomposition tank 35, and a precipitation tank 40 are provided. The filter 19 is an example of a first filter.

  And the water of the said pond 1 is sent by the filter water feeding submersible pump 2 to the upper part of the filter 19 through the filter water feeding piping 24. FIG. As a result, suspended substances including organic substances contained in the water of the pond 1 are deposited on the surface of the filter medium of the filter 19. Further, from the lower portion of the filter 19, the water to be treated that has been filtered flows into the pump pit 17 through the water supply pipe 34. The quality of the water to be treated in the pump pit 17 is inspected by a water quality inspection device (not shown).

  On the other hand, the organic sludge which was a suspended substance deposited on the filter medium surface of the filter 19 passes through the backwash pipe 33 by the filter backwash pump 15 and is transferred to the organic sludge decomposition tank 35.

  In addition, the water to be treated introduced into the pump pit 17 and from which suspended substances are removed is supplied to the ozone micro / nano bubble generation tank 3 as an example of the micro / nano bubble generation tank by the pit pump 23 or an example of the nano bubble generation tank. The ozone nanobubble generation water tank 16 is introduced.

  Whether to introduce into the ozone micro-nano bubble generation water tank 3 or to introduce into the ozone nano-bubble generation water tank 16 is determined by a control device (not shown) based on the inspection result of the water quality inspection device. That is, the control device controls the opening and closing of the valves 20 and 40 based on the inspection result by the water quality inspection device.

  The opening and closing of the valves 20 and 40 will be described in more detail. During the period when there are many suspended solids as organic matter, that is, during the summer when the eutrophication of the pond 1 is extremely advanced, the valve 20 is closed and the valve 44 is opened. Then, the water to be treated in the pump pit 17 is introduced only into the ozone nanobubble generation water tank 16. Further, during the winter season when the eutrophication of the pond 1 does not progress, the valve 20 is opened and the valve 44 is closed, and the water to be treated in the pump pit 17 is introduced only into the ozone micro / nano bubble generating water tank 3. Then, in the spring and autumn seasons when the eutrophication state of the pond 1 is normal, both the valve 20 and the valve 44 are opened, and the water to be treated in the pump pit 17 is made into the ozone micro / nano bubble generating tank 3 and the ozone. It introduce | transduces into both the nano bubble generation | occurrence | production water tank 16. FIG. The opening degree of each of the valves 20 and 44 in spring and autumn is adjusted based on the inspection result by the water quality inspection device, and the amount of treated water introduced into the ozone micro / nano bubble generation tank 3 and the ozone nano bubble generation tank 16 is determined. Is done.

  The ozone micro / nano bubble generating water tank 3 is provided with an underwater pump type ozone micro / nano bubble generating device 48 and a swirling flow type ozone micro / nano bubble generating device 49.

  The submersible pump type ozone micro / nano bubble generator 48 includes a submersible pump type ozone micro / nano bubble generator 4 installed inside the ozone micro / nano bubble generation water tank 3, and a blower 5 installed outside the ozone micro / nano bubble generation water tank 3. have. The submerged pump type ozone micro / nano bubble generator 4 generates an ozone micro / nano bubble water flow 8.

  In addition to the blower 5, the submersible pump type ozone micro / nano bubble generator 4 includes an air suction pipe 72, an ozone generator 66, an air flow meter 43, an air pipe 6 and a needle valve 7.

  The ozone generator 66 generates ozone with the air introduced from the air suction pipe 72. A necessary amount of the air containing ozone is supplied to the blower 5. This amount of air is accurately measured by the air flow meter 43.

  The blower 5 is connected to a needle valve 7 through an air pipe 6. The needle valve 7 accurately adjusts the amount of air flowing from the blower 5 into the submersible pump type ozone micro / nano bubble generator 4. As a result, the amount of air required by the submersible pump type ozone micro / nano bubble generator 4 is accurately supplied from the blower 5 to the submersible pump type ozone micro / nano bubble generator 4.

  On the other hand, the swirl type ozone micro / nano bubble generation device 49 includes a swirl type ozone micro / nano bubble generation unit 10 installed inside the ozone micro / nano bubble generation water tank 3 and a circulation installed outside the ozone micro / nano bubble generation water tank 3. And a pump 13. The swirl flow type ozone micro / nano bubble generation unit 10 generates an ozone micro / nano bubble water flow 8.

  In addition to the circulation pump 13, the swirling flow type ozone micro / nano bubble generating unit 10 includes an air suction pipe 73, an ozone generator 67, an air flow meter 27, a needle valve 11, an air pipe 12, a needle valve 21, and water. A pipe 14 is attached.

  The ozone generator 67 generates ozone with the air introduced from the air suction pipe 73. The air containing ozone flows into the swirl type ozone micro / nano bubble generation unit 10 through the air pipe 12. This amount of air is accurately measured by the air flow meter 27. The amount of air flowing into the swirl type ozone micro / nano bubble generator 10 is adjusted by a needle valve 11.

  And again, ozone micro-nano bubble generation tank 3, ozone nano-bubble generation from filter 19 by adjusting valves 20, 44 installed on the outlet side of water pipe 18 depending on the eutrophication state of pond 1 The flow rate of the water to be treated toward the water tank 16 is controlled, and this water to be treated flows into at least one of the ozone micro-nano bubble generation water tank 3 and the ozone nano-bubble generation water tank 16.

  A submersible pump type ozone micro / nano bubble generator 4 is arranged on the inlet side of the ozone micro / nano bubble generating water tank 3, and a blower 5 and an air pipe 6 are connected to the submersible pump type ozone micro / nano bubble generator 4. On the other hand, on the side close to the overflow pipe 30 on the outlet side of the ozone micro-nano bubble generation water tank 3, the swirl type ozone micro-nano bubble generation unit 10 is arranged. The swirling flow type ozone micro / nano bubble generating unit 10 is connected to a water pipe 14 that is a suction pipe of the circulation pump 13 and a circulation pump 13.

  Accordingly, the water to be treated which has flowed into the ozone micro / nano bubble generating water tank 3 from the filter 19 contains a relatively large size of ozone micro / nano bubbles generated by the submersible pump type ozone micro / nano bubble generator 4 and then swirl type ozone. Introduced into the micro / nano bubble generation unit 10 includes a relatively small size of ozone micro / nano bubbles generated by the swirling flow type ozone micro / nano bubble generation unit 10.

  As a result, the amount of ozone micro-nano bubbles contained in the water to be treated increases, and the action of ozone micro-nano bubbles can be enhanced.

  By the way, by precisely controlling the amount of air supplied to the submersible pump type ozone micro / nano bubble generator 4 and the swirling type ozone micro / nano bubble generator 10, the desired ozone micro / nano bubbles are generated. In many cases, the desired ozone micro-nano bubbles are not generated, and ozone millibubbles are generated.

  Specifically, the air suction amount of the submersible pump type ozone micro / nano bubble generator 4 is 5 liters / minute, and the air suction amount of the swirling flow type ozone micro / nano bubble generator 10 is 1 liter / minute. This air intake amount of 1 liter / min is effective for forming ozone ozone micro-nano bubbles having a small size.

  The operation of the circulation pump 13 related to the submersible pump type ozone micro / nano bubble generator 4 and the swirl type ozone micro / nano bubble generator 10 can be freely selected by a timer (not shown) according to the purpose.

  Further, the water to be treated in the pump pit 17 flows into the ozone nanobubble generating water tank 16 when the submersible pump 23 is operated and the valve 44 is opened.

  An ozone nanobubble generator 50 is installed in the ozone nanobubble generating water tank 16. The ozone nanobubble generator 50 has an ozone nanobubble generator 38 installed outside the nanobubble generating water tank 16.

  Housed in the ozone nanobubble generator 38 are a circulation pump 22 and an ozone nanobubble generator 42 connected to a discharge port of the circulation pump 22 via a pipe. The electric motor of the circulation pump 22 is much larger than the electric motors of the submersible pump type ozone micro / nano bubble generator 4 and the circulation pump 13. Thereby, the electric motor of the circulation pump 22 can produce a large amount of ozone nanobubbles.

  That is, the amount of ozone nanobubbles generated by the ozone nanobubble generator 38 is determined by the amount of air sucked by the ozone nanobubble generator 38 and the scale specifications of the motor of the circulation pump 22.

  A suction port 26 is provided at the tip of the water pipe that is the suction pipe of the circulation pump 22. The circulation pump 22 sucks in the water to be treated in the ozone nanobubble generating water tank 16 from the suction port 26 and supplies the sucked water to be treated to the ozone nanobubble generating unit 42 at a high pressure.

  A needle valve 29, an air flow meter 28 and an ozone generator 68 are connected to the ozone nanobubble generator 42. The ozone generator 68 generates ozone with the air introduced from the air suction pipe 74. The air containing ozone flows into the ozone nanobubble generator 42. This amount of air can be accurately measured by the air flow meter 28. Further, the amount of air flowing from the ozone generator 68 into the ozone nanobubble generator 42 is adjusted by the needle valve 29. Thereby, the air containing ozone by the ozone generator 68 can be supplied to the ozone nanobubble generator 42 by adjusting the amount of air.

  The ozone nanobubble generator 42 discharges a mixture of gas and liquid containing ozone nanobubbles. This mixture enters the ozone nanobubble generating water tank 16 from the discharge port 25 through the water pipe. As a result, an ozone nanobubble water stream 32 is generated in the ozone nanobubble generating water tank 16. The ozone nanobubbles contained in the ozone nanobubble water stream 32 have a higher water quality improvement effect than the ozone micronanobubbles.

  Therefore, even if eutrophication of the pond 1 is progressing, the water of the pond 1 can be introduced into the ozone nanobubble generating water tank 16 and sufficiently purified.

  On the other hand, the backwash water containing the organic sludge from the filter 19 is introduced into the organic sludge decomposition tank 35.

  In the organic sludge decomposition tank 35, depending on the eutrophication state of the pond 1, that is, according to the water quality of the pond 1, when (A) ozone nano bubbles are introduced, (B) when ozone micro nano bubbles are introduced, (C) There are three cases where both ozone nanobubbles and ozone micronanobubbles are introduced.

  As described above, when the eutrophication of the pond 1 is extremely advanced and the water quality of the pond 1 is the worst, only the ozone nanobubbles are introduced into the organic sludge decomposition tank 35. When the water quality of the pond 1 is good and the amount of organic sludge introduced is small, only ozone micro-nano bubbles are introduced into the organic sludge decomposition tank 35. Then, both ozone nanobubbles and ozone micronanobubbles are introduced into the organic sludge decomposition tank 35 when the water quality is intermediate between the bad summer season and the good winter season, as in the spring and autumn seasons.

  The above-mentioned ozone nanobubbles strongly oxidize and decompose organic sludge and act to mineralize organic sludge and reduce sludge.

  The above-mentioned ozone micro-nano bubbles also oxidize and decompose organic sludge, which acts to mineralize organic sludge and reduce sludge. However, compared with ozone nano-bubbles, the effectiveness is extremely reduced although it differs depending on the case. The

  As for the water quality of the pond 1 above, algae often grow abnormally in summer, and eutrophication of the pond progresses. Conversely, in winter, when the water temperature is low, algae do not breed and the water quality is good. Spring and autumn ponds 1 have intermediate water quality between summer ponds 1 and winter ponds 1.

  A diffuser pipe 36 is installed inside the organic sludge decomposition tank 35. The air from the air diffuser 36 through the blower 47 generates a water flow 37 and air bubbles 39 to stir the contents of the organic sludge decomposition tank 35. Thereby, the organic sludge from the filter 19 effectively comes into contact with the ozone nanobubbles, the ozone micronanobubbles, or both the ozone nanobubbles and the ozone micronanobubbles, so that the organic sludge changes to mineralized sludge. The air diffuser 36 and the blower 47 constitute an example of a stirring device.

  And the to-be-processed water which came out of the said organic substance sludge decomposition tank 35 is introduce | transduced into the sedimentation tank 40 with mineralized sludge, and is isolate | separated into mineralized sludge and treated water. At this time, since the mineralized sludge is much superior in sedimentation than the organic sludge, a scraper need not be installed in the settling tank 40.

  The treated water in the settling tank 40 returns to the pond 1 through the treated water pipe 41, but may be specified as, for example, agricultural water without returning to the pond 1.

  On the other hand, the mineralized sludge settled in the settling tank 40 is introduced into a dehydrator (not shown) through a settling tank outlet pipe 75. The sludge dehydrated by this dehydrator can be used as a soil improvement material.

  Moreover, if the said submersible pump type ozone micro nano bubble generator 4, the swirl type (non-submersible pump type) ozone micro nano bubble generator 10 and the nano bubble generator 38 are commercially available, they do not limit manufacturers. However, in the first embodiment, the product of Nomura Electronics Co., Ltd. is used as the submersible pump type ozone micro-nano bubble generator 4, and the product of the Nano Planet Research Laboratory is used as the swirling flow type (non-submersible pump type) ozone micro-nano bubble generator 10. The product of Kyowa Kikai Co., Ltd. was adopted as the nanobubble generator 38.

  The submerged pump type ozone micro / nano bubble generator 4, swirl type ozone micro / nano bubble generator 10 and ozone nano bubble generator 38 are sold in large numbers by other manufacturers, but may be selected according to the purpose.

Here, three types of bubbles will be described.
(I) Ozone microbubbles are bubbles having a diameter of 10 to several tens of μm and containing ozone at the time of generation. In addition, ozone microbubbles change to ozone micronanobubbles by contraction movement after generation.
(II) Ozone micro-nano bubbles are bubbles having a diameter of several hundred nm or more and less than 10 μm and containing ozone.
(III) Ozone nanobubbles are bubbles containing ozone having a diameter of less than several hundred nm.

  In the first embodiment, the water quality inspection device inspects the quality of the water to be treated in the pump pit 17 and the control device (not shown) opens and closes the valves 20 and 44 based on the inspection result. May inspect the quality of the water to be treated in the pump pit 17, and a person may open and close the valves 20 and 44 based on the inspection result.
