Description

Floating type comprehensive water treatment equipment and water treatment system using same

Technical Field

The utility model relates to a water treatment facilities particularly, relates to a float water treatment system that water treatment facilities and applied this equipment are synthesized to formula.

Background

The water treatment objects mainly comprise natural water bodies and artificial water bodies. Such as river and lake water bodies, garden landscape water bodies, culture water bodies, fountains, swimming pools, water parks and the like. Most of the water bodies have the characteristics of low pollutant concentration, diversified pollution sources and great water quantity, have high requirements on water quality and sanitary conditions, and can continuously generate artificial or non-artificial pollution in the using process. Because the periodic replacement of the stored water in these water bodies causes huge waste of water resources and high cost, the water circulation treatment equipment is mostly adopted to purify these water bodies at present.

The traditional water circulation treatment equipment is fixed on the shore (or a shore machine room) or in a water body to be treated, so that a plurality of water treatment equipment are required to be arranged for the water body with larger water surface scale, such as a large lake, a long river and the like, on one hand, the facility cost is increased, and on the other hand, the workload of maintenance and cleaning is increased.

Boat-type water treatment apparatuses have been considered. For example, in chinese patent ZL00124828.6, a ship-type air-float algae removal device and method is disclosed. This ship formula air supporting removes equipment that algae device adopted through installing a whole set of water treatment process on the ship, specifically, includes: the device comprises a tubular static mixing reactor for dosing and mixing, a flocculation reactor, a sludge tank, an air floatation contact chamber, a separation chamber, an overflow weir and the like which are connected into a whole, and algae in the water body is removed by the air floatation principle. According to the scheme disclosed in the specification of the patent, only the water treatment equipment is arranged on a ship, raw water to be treated is lifted into the treatment equipment on the ship by a water pump, the raw water is treated on the ship, and the treated water is discharged back to a water body. That is, compared to a water circulation treatment apparatus disposed on the bank of a water body or disposed in the water body, the solution actually changes only the carrier of the water treatment apparatus without changing the structure and function of the water treatment apparatus. Therefore, the treatment capacity of the water treatment apparatus obtained by implementing this embodiment is predictably quite limited due to the limitations of the load and volume of the ship as a carrier, and the like. From the data described in the specification of the patent, the design flow range is 1.0-4.0 cubic meter per hour, so that the water treatment requirements of large water bodies such as rivers and lakes are difficult to meet, and particularly, the actual treatment flow rate is often reduced under the condition that the water quality of the water body to be treated is poor.

For another example, chinese patent application 201210162107.7 discloses a ship type sewage treatment system based on SBR process, which is also designed to realize the mobile function of the water treatment equipment by installing the SBR water treatment equipment on the hull of the ship with retractable wheels, and to save facilities such as a regulation tank, a primary sedimentation tank and a secondary sedimentation tank which are installed on the land. However, as described in the specification of the present patent application, the sewage treatment process of the ship type sewage treatment system consists of the mature sewage treatment technology of anaerobic contact oxidation and SBR. That is, as for the water treatment process itself, the existing mature technology is adopted. The SBR, which is a sequencing batch Activated Sludge Process, is generally called a sequencing batch Activated Sludge Process (SBR Process). SBR is a process of biologically treating activated sludge for wastewater based on degradation of organic matters, ammonia, nitrogen and other pollutants in wastewater by suspended microorganisms under aerobic conditions. The sewage treatment device operates in an intermittent aeration mode according to time sequence, changes the growth environment of activated sludge, and is widely accepted and adopted by the whole world. The common process of SBR is divided into five stages: water inlet, aeration reaction, precipitation (sedimentation), water decanting (water outlet), and standing (standing or standby).

The root cause of the deterioration of the water quality of rivers and lakes is the eutrophication of water caused by the discharge of pollutants, so that a large amount of oxygen consuming organisms such as algae are excessively proliferated, resulting in the lack of oxygen in the water, thereby destroying the original ecosystem of the water body. Therefore, the principle of water circulation treatment is a fundamental solution by increasing the oxygen content of water in a water body. Further, a dissolved oxygen aeration method can be adopted to increase the oxygen content of the water body.

The proposal of combining a water circulation treatment device with a dissolved oxygen aeration device has been applied. For example, in the publication of patent publication CN1297490C of the invention in china, an apparatus for treating water in rivers and lakes and a method thereof are disclosed. The water treatment device comprises a sleeve-shaped device for receiving the new water, wherein the bottom of an inner cylinder is connected with a water inlet pipe, V-shaped overflow grooves are radially and uniformly distributed between the inner cylinder and an outer cylinder, and the bottom edges and the two upper edges of the V-shaped overflow grooves form a water curtain. Harmful gas in water volatilizes through the contact of cascade and atmosphere to make the oxygen in the air dissolve in water, thereby realize the oxidation, the activation and the freshing of water.

For another example, chinese utility model ZL201320139623.8 discloses a "dissolved oxygen aeration apparatus and a water treatment apparatus using the same", which provides power for dissolved oxygen aeration by using potential energy of the drop between the water surface of the water to be treated outside the apparatus and the drop water surface inside the apparatus, and also makes the movement of the water inside the apparatus more stable; the control water surface inside the device is basically stable through controlling the water inflow, so that the height difference from the falling water surface to the water surface is ensured, and the space of the falling type dissolved oxygen aeration is ensured.

Although, as described above, it has been considered to combine the existing water circulation treatment apparatus with the hull, no proposal has been made to combine the water treatment apparatus including the dissolved oxygen aeration device with a floating carrier such as the hull, and no concrete proposal has been made for a floating type integrated water treatment apparatus based on the dissolved oxygen aeration technique.

On the other hand, in recent years, a technique of purifying water by a biological means has also been developed. The biological purification of sewage is usually carried out by two microbial populations, anaerobic and aerobic. Wherein, aerobic microbial's aerobic process need let in a large amount of compressed air from aerobic effluent water sump bottom to pending sewage in, for the aerobic microbial of waste water provides sufficient oxygen, this process is also called aeration process to supply aerobic microbial to utilize, then remove and reduce organic pollutant and nitrogen phosphorus in aquatic through aerobic microbial's decomposition, thereby realize the purification of water.

For example, in chinese patent application publication CN104710085A, a high efficiency AOAS integrated sewage treatment apparatus and process thereof is disclosed, wherein the sewage treatment apparatus comprises a primary reaction sedimentation tank and a secondary reaction sedimentation tank for performing aerobic treatment, and the primary reaction sedimentation tank and the secondary reaction sedimentation tank are aerated by an aeration system (comprising a blower, an air supply connection pipe, and aeration discs respectively disposed at the bottoms of the primary reaction sedimentation tank and the secondary reaction sedimentation tank). For another example, in chinese patent application publication CN104724817A, a net cage type biological carrier and an immobilized microorganism sewage treatment apparatus are disclosed, wherein the net cage type biological carrier is composed of a net cage and a biological filler filled in the net cage, and is stacked in a sewage treatment tank of the immobilized microorganism sewage treatment apparatus.

In the prior art solutions such as disclosed in the above patent applications, aerobic treatment by microorganisms is achieved by providing a sewage treatment tank or a sedimentation tank as a reaction vessel, and a certain amount of land needs to be occupied near the water body to be treated, which may damage the overall environment around the water body to be treated and is also not easy to be achieved for landscape water bodies, urban rivers, and the like; the aeration pipe made of steel pipe or plastic pipe is directly laid at the bottom of the aeration tank, and the aeration holes on the wall of the aeration pipe disperse the quantitative air into a large amount of bubbles, although the structure is simple and the resistance is small, the average diameter of the bubbles is large, the oxygen transfer efficiency between gas and liquid is low, and the holes are easily blocked by sludge or microorganism; in addition, the water in the pool needs to be drained during equipment installation, maintenance, movement and replacement, and the equipment is very inconvenient.

As described above, there has not been proposed a solution of combining a water treatment apparatus including a dissolved oxygen aeration device with a floating carrier such as a ship hull, and further, there has not been given a concrete solution of a floating type integrated water treatment apparatus based on a dissolved oxygen aeration technique. According to the embodiment of the utility model, a float formula and synthesize water treatment facilities is provided, it will dissolve water treatment technologies such as oxygen aeration technique, filtration technique, microbial purification and integrate together, carry out circulating water treatment to the water that bears this equipment to can realize the unified collection, centralized processing to filtering the sediment filth.

The floating type integrated water treatment equipment is preferably suitable for rivers and lakes as landscape water bodies. According to the floating type integrated water treatment equipment, the existing water treatment equipment is not combined with the ship body, but a floating platform is designed, and the structure of the floating type integrated water treatment equipment is integrally used for water circulation treatment of a water body; of course, from the perspective of external aesthetics, the configuration of the boat can also be configured by adding external structures and decorations.

Fig. 1 schematically illustrates an enlarged top view partially in section of a floating integrated water treatment apparatus according to an embodiment of the present invention. Fig. 2 is a plan view of the floating type integrated water treatment apparatus corresponding to fig. 1. The structure of the floating type integrated water treatment device according to the embodiment of the present invention can be better understood by combining fig. 1 and 2.

As shown in fig. 1 and 2, the floating type integrated water treatment apparatus has a shape like a boat. On one hand, the appearance design considers that the appearance of the equipment does not influence and damage the overall landscape of the treated water body as much as possible; another aspect is to take into account the mobility of the device in water. Alternatively, the floating type integrated water treatment apparatus according to the embodiment of the present invention may also adopt other shapes, such as a circle, an ellipse, a square, etc.

As shown in fig. 1, the floating integrated water treatment device according to the embodiment of the present invention mainly comprises: a housing unit 100, a culture unit 200, a filtration unit 300, and an aeration unit 400.

The housing unit 100 is the housing structure of the water treatment device for supporting and containing other structures within the device. As previously described, the housing unit 100 may have a boat-like shape from the viewpoint of overall landscape and mobility performance, as shown in fig. 1 and 2. Meanwhile, the housing unit 100 may also have a structure like a hull of a ship so that the water treatment apparatus as a whole floats on the water body in a ship-like manner.

Optionally, a sealed air compartment may be provided in the housing unit 100 to increase the overall buoyancy of the apparatus. The sealed air compartment may be arranged in the front, in the middle or in the rear of the apparatus, for example at the front, in the rear or in the middle side of the housing unit 100, etc. For example, in fig. 1 and 2, two airtight air chambers 101 are provided at the front and rear of the water treatment apparatus housing unit 100, and each airtight air chamber 101 is substantially symmetrical with respect to the central axis of the apparatus, so that the buoyancy of the apparatus can be increased, and the balance of the entire apparatus can be stabilized by the front-rear arrangement and the symmetrical structure. The sealed air chamber 101 may be a single chamber body, which is separated from other chamber body parts inside the equipment by the partition plate 102, or may include a plurality of sub sealed air chambers, which may also be symmetrically distributed about the central axis of the casing 100 from the viewpoint of balance.

Alternatively, the buoyancy and balance of the water treatment device can also be adjusted by adjusting the amount of water injected in the injection compartment by providing the injection compartment.

The culture unit 200, the filter unit 300 and the aeration unit 400 may form separate chambers inside the housing unit 100, respectively, and communicate with each other through pipes (and valves), so that not only the water at different stages of water purification treatment may be prevented from mixing with each other, but also the buoyancy of the apparatus may be increased by using the air-containing space of the chambers.

The culture unit 200 is isolated from the airtight gas container 101 and the filter unit 300 by the partitions 102 and 201, respectively, to form independent chambers. Alternatively, the culture unit 200 may be a sealed chamber, which is in communication with other units or chambers via tubing.

The culture unit 200 comprises a sludge storage cavity 202, a sludge suction pipe 203, a deposition plate 204, an aerator 205, a filler 206 and an aeration pipe 208. As further shown in FIG. 3, the sediment plate 204 is disposed on the bottom side of the culture unit 200 and is sloped to facilitate the collection of sediment in water into the mud storage chamber 202. A mud suction pipe 203 is arranged in the mud storage cavity 202. The suction pipe 203 is connected to a sludge pump 343 (see fig. 5) which may be provided outside the culture unit 200 through a pipe, so that the sludge sucked from the sludge storage chamber 202 is discharged by the sludge pump 343. Optionally, a valve 210 is disposed on the pipeline between the suction pipe 203 and the sludge pump 343 to control the conduction of the pipeline.

According to the embodiment of the present invention, the culture unit 200 is not only used for collecting sludge in water, but also used for culturing microorganisms used for water treatment. The microorganism used for water treatment can be aerobic microorganism generally, and organic pollutants and nitrogen and phosphorus in water are removed and reduced through the decomposition of the microorganism, so that the water is purified. For the cultivation of aerobic microorganisms it is on the one hand necessary that the aqueous environment in which the microorganisms multiply grow has a sufficient oxygen content and on the other hand it is also preferable that the aqueous environment also contains sufficient nutrients.

Microorganisms are attached to the filler serving as the carrier to form a microbial film, and in the process that sewage flows through the microbial film, the sewage is degraded through the adsorption of organic matters, the diffusion of oxygen to the interior of the biological film and the actions of biological oxidation and the like generated in the film. And can simultaneously culture the propagation and growth of microorganisms, so that part of the microorganisms are separated from the filler and enter the water body, and the degradation and water purification effects in a wider range are realized.

The plurality of aerators 205 are connected by the gas pipe 208 to form a gas pipe network (the gas pipe network can have shapes such as round and square), the gas pipe network is arranged below the filler 206, and the filler 206 above the gas pipe network outputs gas, so that on one hand, the aerobic microorganisms in the filler 206 can be supplied with oxygen, and as the gas washes the microorganisms in water, mature microorganisms fall off from the filler 206 and enter the water to further grow and purify the water body, and on the other hand, the oxygen can be directly dissolved into the water. The aerator 205 is arranged at the lower part of the filler 206 and outputs the gas upwards, so that the gas can be driven to enter the filler 206 by the buoyancy of the gas, the aeration and oxygen dissolving efficiency is improved, and meanwhile, the gas pipe 208 and the aerator 205 are arranged at the lower part of the water treatment equipment (as shown in figure 3), the gravity center of the whole equipment can be reduced, and the whole stability is improved. Alternatively, the aerator 205 may be positioned on the side or above the packing 206 by constructing a gas transmission pipe network.

Alternatively, the gas pipe network is supplied with gas by a gas pump 349 disposed outside the culture unit 200, and the supplied gas may be outside air, oxygenated air, oxygen, or the like. Specifically, the controller 346 (which may be disposed in the filter unit 300 as shown in fig. 1 or in other parts of the water treatment facility) may activate the air pump 349 to generate high-pressure air, and make the air reach the aerator 205 connected to the air pipe 208 via the air pipe 208, and discharge the micro-bubbles through the aeration holes on the membrane of the micro-porous aerator 205, so as to achieve aeration and oxygen dissolution in the sewage, and provide sufficient oxygen for the growth of microorganisms.

Optionally, a gas-liquid separation valve 207 is disposed at the top of the sealed cabin of the culture unit 200, so that on one hand, the gas output by the aerator 205 passes through the water and the filler 206 and then is released from the gas-liquid separation valve 207 to the outside of the apparatus, and on the other hand, the water inside the sealed cabin of the culture unit 200 can be prevented from overflowing. Other gases that may be generated by culturing microorganisms and treating water in the culture unit 200 may also be discharged from the gas-liquid separation valve 207.

Optionally, one or more spoilers 209 (shown in FIG. 1) may be disposed within the culture unit 200, the spoilers 209 being distributed within the cavity of the culture unit 200, such as near the water inlet of the culture unit 200, the spoilers 209 slowing the water flow rate and promoting the gradual deposition of contaminants and impurities in the water.

As shown in FIGS. 1 to 3, in order to increase the amount of microorganism culture, the amount of water treatment, etc., culture units 200 may be provided at both the front and rear of the water treatment apparatus. FIG. 4 is an enlarged partial cross-sectional view corresponding to the cut line D-D indicated in FIG. 2, and one arrangement of gas delivery conduits can be seen in FIG. 4.

The floating type integrated water treatment equipment according to the embodiment of the present invention further comprises an aeration unit 400 and a filtering unit 300 as described above. Wherein, the aeration unit 400 is used for carrying out aeration treatment on the water to be treated, so that the water to be treated obtains dissolved oxygen in contact with air, and harmful gases in the water are exchanged into the air; the filtering unit 300 is used for filtering and purifying the water subjected to the aeration treatment by the aeration unit 400. Further, in the process of backwashing the filter unit 300, water (sewage) formed after backwashing is injected into the culture unit 200, and the aforementioned sewage sedimentation treatment and microbial culture are performed. Specifically, the filtering unit 300 filters water and retains certain filter residue dirt, when the filtering unit 300 is backwashed, the filter residue dirt is washed to the culture unit 200, on one hand, the dirt and sludge can be deposited through the deposition plate 204, the sludge storage cavity 202, the sludge suction pipe 203 and other parts, and on the other hand, the filter residue dirt can also provide nutrients for the propagation and growth of microorganisms. In other words, the filter unit 300 is communicated with the culture unit 200 when the filter unit 300 is backwashed, and the culture unit 200 can independently operate to culture, propagate, grow, and release microorganisms, etc. at other times.

The spatial arrangement and the main structure of the aeration unit 400 and the filter unit 300 can be seen in conjunction with fig. 1 and 2.
