The existing treatment facilities lack structures to effectively prevent sediment deposition, or the filtration link is not perfectly designed, making it difficult to fully meet the actual needs of biochemical treatment of aquaculture auxiliary ponds. Therefore, a more reasonable and comprehensive structure of aquaculture auxiliary pond biochemical treatment pool is needed to solve the above problems, improve the water treatment effect and ensure the stable operation of aquaculture. SUMMARY

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a kind of biochemical treatment pool structure of aquaculture auxiliary pond.

[0004] To achieve the above-mentioned purpose, the utility model provides a kind of biochemical treatment pool structure of aquaculture auxiliary pond, which includes a containing pool, a water outlet pipeline, a water inlet pipeline and a biochemical treatment assembly arranged in the containing pool. The biochemical treatment assembly and the water inlet pipeline are in communication with the containing pool, and the biochemical treatment assembly is used to carry the microbial bodies for purifying the water in the containing pool. The water inlet pipeline includes a first pipe body in communication with the containing pool, and an inlet screen mesh is arranged at one end of the first pipe body away from the containing pool. The inlet screen mesh is arranged in the aquaculture pond, and the inlet screen mesh is a hollow screen mesh structure with screen holes.

[0005] The biochemical treatment assembly is in communication with the containing pool and the water outlet pipeline, which can perform biochemical treatment on wastewater. The first pipe body of the water inlet pipeline is in communication with the containing pool, and the other end is connected to the inlet screen mesh arranged in the aquaculture pond. The inlet screen mesh is a hollow screen mesh structure with screen holes, which can intercept fish entering the biochemical pool with a solid structure with screen holes, improving the system stability. The water source to be treated is discharged by the water outlet pipeline after being treated by the biochemical treatment assembly, realizing the purification of aquaculture wastewater, improving the water quality, and being beneficial to the improvement and protection of the aquaculture environment. The whole structure is reasonable in design, easy to implement and apply.

[0006] The aquaculture auxiliary pond biochemical treatment pool structure includes a plurality of aeration devices arranged on the inner side of the containing pool, and the aeration devices are arranged in a ring shape inside the containing pool.

[0007] The aeration device comprises an aeration ring arranged in the containing pool, an aeration connecting pipe in communication with the aeration ring, and an external air source supply member in detachable and sealable connection with the aeration connecting pipe through a quick connector.

[0008] The aeration device comprises an aeration ring arranged in the containing pool, an aeration connecting pipe in communication with the aeration ring, and an external air source supply member in detachable and sealable connection with the aeration connecting pipe through a quick connector.

[0009] The water aquaculture auxiliary pool biochemical treatment pool structure further comprises a gas stripping assembly arranged in the containing pool, with the water inlet end of the gas stripping assembly in communication with the water body of the containing pool and the water outlet end of the gas stripping assembly in communication with the water outlet pipeline.

[0010] The gas stripping assembly comprises a pneumatic conveying assembly, which comprises a pneumatic conveying cone, an aeration base plate in communication with the bottom surface of the pneumatic conveying cone, and a water outlet pipeline in communication with the pneumatic conveying cone.

[0011] The pneumatic conveying assembly in the gas stripping assembly is composed of a pneumatic conveying cone and an aeration base plate, the pneumatic conveying cone is tapered from narrow top to wide bottom, the side edge is connected with a water inlet filter, the bottom is communicated with the aeration base plate, the top end is connected with a water outlet pipeline, and the water outlet pipeline is provided with an air inlet extending out of the water surface. When running, the water source to be treated first removes impurities through the water inlet filter, and the filtered water source flows into the lower part of the pneumatic conveying cone, at this time the aeration base plate releases air flow through the aeration holes, and forms a gas-liquid mixed upward flow with the water body, which accelerates upward under the action of the tapered section of the pneumatic conveying cone; at the same time, the air inlet supplies air source to the water outlet pipeline, further pushing the gas-liquid mixed flow to be quickly conveyed to the external treatment unit. This design not only effectively intercepts impurities in the water through filtration, but also improves the water flow conveying efficiency by using the principle of pneumatic conveying, avoiding the influence of water flow stagnation on the treatment effect, realizing the deep purification and efficient transmission of aquaculture wastewater, and ensuring the stable operation and good treatment effect of the entire biochemical treatment system.

[0012] The water inlet filter includes a filter shell and filter beads filled in the filter shell, and the outer side of the filter shell is provided with filter holes, and the water source to be treated flows into the filter shell through the filter holes.

[0013] The water inlet filter is composed of a filter shell and filter beads, the outer side of the filter shell is covered with filter holes, and the inside is filled with filter beads. When the water source to be treated flows into the containing pool from the breeding pool, it will enter the inside of the filter shell through the filter holes on the filter shell. In this process, the filter holes can intercept larger particle impurities, and the water flow entering the filter shell will fully contact with the filled filter beads. The filter beads, relying on their porous structure and adsorption properties, further adsorb and intercept suspended solids, small particles and part of pollutants in the water, and then convey the preliminary purified water to the pneumatic conveying cone for subsequent treatment. This design effectively reduces the load of the subsequent treatment unit, improves the treatment accuracy and efficiency of the entire biochemical treatment system, and ensures that the discharged water quality meets the purification requirements of the aquaculture environment.

[0014] The extended end of the aeration connecting pipe is provided with a quick connector for detachable connection with an external air source supply.

[0015] The quick connector is installed at one end of the aeration connecting pipe extending out of the water surface of the containing pool. In actual application, through simple plug-in and plug-out operation, the connection or separation with the external air source supply can be quickly realized. This detachable connection method saves a lot of manpower and time cost without the need for complex tools and cumbersome operation procedures during equipment installation and debugging, daily maintenance and replacement of air source supply. At the same time, it is also convenient to flexibly replace different specifications or types of air source supplies according to different treatment needs and working conditions, to ensure stable air supply of the aeration device and provide sufficient oxygen for the water body in the containing pool, promote the efficient operation of the biochemical treatment assembly, and effectively improve the wastewater treatment effect.

[0016] The aeration device further comprises a fixing clamp, and the aeration connecting pipe is fixedly arranged on the inner side of the containing pool via the fixing clamp.

[0017] The fixing clamp is installed on the inner side of the containing pool, and the aeration connecting pipe is fixed through the fixing clamp, which can effectively prevent the aeration connecting pipe from shaking or moving in the containing pool. In this way, whether it is the vibration generated by the aeration device during system operation or the impact caused by water flow, the position and connection state of the aeration connecting pipe will not be affected, ensuring that the aeration ring can stably deliver gas to the water body, maintaining the uniformity and continuity of aeration, and ensuring the stable operation of the biochemical treatment assembly, thereby improving the treatment effect of the entire biochemical treatment pool on aquaculture wastewater, while reducing the risk of component damage caused by pipe shaking and prolonging the service life of the equipment.

[0018] The containing pool is also provided with a flushing pipe, which flushes the sediment at the bottom of the pool and moves the sediment to the drain to empty the containing pool.

[0019] The flushing pipe is installed in the containing pool, and water flow is provided by an external water source or a pressure device. When the containing pool needs to be cleaned, the flushing pipe is turned on, and the strong water flow flushes the bottom of the pool, disperses the long-term deposited sediment such as sludge and impurities, and moves them to the drain with the help of the water flow, and finally discharges them outside the pool with the water flow, realizing the rapid emptying of the containing pool. This design not only effectively prevents the growth of bacteria and consumption of oxygen in the sediment, affecting the water environment and treatment effect, but also reduces the workload and difficulty of manual cleaning, ensuring that the biochemical treatment pool is in a high-efficiency and stable operation state for a long time, providing strong support for the continuous purification of aquaculture wastewater.

[0020] A flow control valve is arranged between the gas stripping assembly and the water outlet pipeline, and the flow control valve can automatically adjust the opening degree according to the water level in the containing pool.

[0021] The flow control valve is installed at the connection between the gas stripping assembly and the water outlet pipeline, and a water level sensing and control device is arranged inside. During operation, the flow control valve monitors the water level in the containing pool in real time. When the water level rises, the valve automatically increases the opening degree to speed up the water flow discharge speed to prevent the water level in the containing pool from being too high. When the water level drops, the valve correspondingly reduces the opening degree to ensure the stable output of water flow. This automatic adjustment mechanism based on water level effectively avoids the impact on the subsequent treatment unit caused by the fluctuation of water flow, ensures the stability of the entire biochemical treatment process, and reduces the tedious operation of manual adjustment, so that the treatment system can more efficiently and intelligently cope with the wastewater treatment demand under different working conditions.

[0022] The bottom of the containing pool is in a funnel-shaped inclined structure, and the drain is arranged at the lowest point of the funnel, which can more efficiently collect and discharge the sediment together with the flushing pipe.

[0023] The inner wall of the pneumatic conveying cone of the gas stripping assembly is provided with spiral guide grooves, and the gas-liquid mixed flow generates spiral upward movement under the action of the spiral guide grooves, further enhancing the mixing and conveying efficiency.

[0024] The air hole exposed to the water surface can balance the air pressure inside and outside the filter shell when the water source to be treated enters the filter shell through the filter hole and contacts the filter beads for filtration, so that the negative pressure formed in the shell due to the continuous inflow of water is avoided, and the water flow is hindered, thereby ensuring that the wastewater can be smoothly filtered. At the same time, the air hole exposed to the water surface can make air enter the filter shell, create an aerobic environment inside, inhibit the breeding of anaerobic microorganisms, and prevent the generation of harmful gases to affect the water quality. In addition, when the equipment is stopped or maintained, the air hole facilitates the discharge of residual water in the filter shell, facilitates the drying and maintenance of the filter beads, and prolongs the service life. This design is simple but practical, ensures stable and efficient operation of the water inlet filter, and improves the reliability and treatment effect of the entire biochemical treatment system.

[0025] The beneficial effects of the utility model are as follows: the inlet screen of the water inlet pipeline intercepts fish and preliminarily filters wastewater and then introduces the wastewater into the containing pool; the annular aeration device in the structure of the aquaculture auxiliary pool biochemical treatment pool releases bubbles to the water body through an external air source, which not only stirs the water body to prevent sediment accumulation, but also provides oxygen for microorganisms to decompose pollutants; the water inlet filter of the gas stripping assembly uses filter beads to adsorb impurities, and the pneumatic conveying assembly accelerates the filtered wastewater to the external treatment unit through gas-liquid mixed upward flow. These designs effectively improve the wastewater treatment efficiency, ensure stable operation of the system, reduce manual maintenance cost, realize deep purification of aquaculture wastewater, significantly improve the water quality of aquaculture, and provide strong support for sustainable development of the aquaculture environment.

The side edge of the pneumatic conveying cone 14 is provided with a water inlet filter 17 communicated with the pneumatic conveying cone 14. After the water source to be treated is filtered through the water inlet filter 17, the filtered water source flows into the lower part of the pneumatic conveying cone 14.

In operation, the water source to be treated first removes impurities through the water inlet filter 17, and the filtered water source flows into the lower part of the pneumatic conveying cone 14. At this time, the aeration base 15 releases gas flow through the aeration holes, and forms a gas-liquid mixed flow that rises. Under the action of the tapered section of the pneumatic conveying cone 14, the gas-liquid mixed flow is accelerated upward. At the same time, the air inlet 16 supplies air to the water outlet pipeline 2, further pushing the gas-liquid mixed flow to be quickly conveyed to the external treatment unit.

When the water source to be treated flows from the breeding pond into the containing pool 1, it will enter the inside of the filter shell 18 through the filter holes on the filter shell 18. In this process, the filter holes can intercept larger particle impurities, and the water flow entering the filter shell 18 will be in full contact with the filled filter beads 19. The filter beads 19, relying on their porous structure and adsorption properties, further adsorb and intercept suspended solids, small particles and part of pollutants in the water, preliminarily purify the water source to be treated, and then convey it to the pneumatic conveying cone 14 for subsequent treatment.

At the same time, the air holes exposed to the water surface can make air enter the filter shell 18, create an aerobic environment inside, inhibit the breeding of anaerobic microorganisms, and prevent the generation of harmful gases to affect the water quality. In addition, when the equipment is shut down or maintained, the air holes can facilitate the discharge of residual water in the filter shell 18, facilitate the drying and maintenance of the filter beads 19, and prolong the service life.
