[0026] In related technologies, pond effluent is treated by natural sedimentation or a combination of natural sedimentation and biodegradation. While natural sedimentation has a large treatment capacity and high efficiency, it is less effective in treating water with excess nutrients after feed addition and cannot achieve the desired purification effect. In contrast, the combination of natural sedimentation and biodegradation can treat water with excess nutrients after feed addition and achieve the desired purification effect, but the treatment capacity is smaller and the efficiency is lower.

[0027] This utility model provides a pond tailwater treatment device that can achieve the desired purification effect while maintaining high treatment efficiency.

[0028] The following is for reference. Figure 1 This invention describes a pond tailwater treatment device according to an embodiment of the present invention.

[0029] The pond tailwater treatment equipment according to an embodiment of the present invention includes a sedimentation tank 100, a degradation tank 200, and a control system.

[0030] The sedimentation tank 100 is provided with a sedimentation inlet, a sedimentation outlet and a first outlet. The sedimentation inlet is used to draw water from the pond, and the first outlet is used to drain water into the pond. The first outlet is provided with a first drain pipe 610 connected to the pond. The sedimentation tank 100 is used to treat the tailwater of the pond by sedimentation. The sedimentation tank 100 is a conventional component in the art, and its specific structure will not be described in detail here.

[0031] The degradation tank 200 is provided with a degradation inlet and a second outlet. The sedimentation outlet is connected to the degradation inlet, and the second outlet is used to drain water into the pond. The second outlet is provided with a second drainage pipe 620 connected to the pond. The degradation tank 200 is used to biodegrade the pond effluent. The degradation tank 200 is a conventional component in this field, and its specific structure will not be described in detail here.

[0032] The control system includes at least two switching valves, which are respectively located at the sedimentation outlet and the first outlet. One of the switching valves is called the first valve 410, which can control the shut-off or opening of the sedimentation outlet. The other switching valve is called the second valve 420, which can control the shut-off or opening of the first outlet.

[0033] In use, pond effluent can be transported to sedimentation tank 100 through sedimentation inlet. When the pond is not fed and is in a conventional aquaculture environment, the operator can control the switch valve of sedimentation outlet to close and the switch valve of the first outlet to open. The pond effluent only undergoes sedimentation treatment in sedimentation tank 100 and does not undergo biodegradation treatment in degradation tank 200, resulting in high treatment efficiency. When the pond is fed, the operator can control the switch valve of sedimentation outlet to open and the switch valve of the first outlet to close. The pond effluent undergoes both sedimentation treatment in sedimentation tank 100 and biodegradation treatment in degradation tank 200, achieving the expected purification effect.

[0034] In some embodiments of this utility model, the sedimentation tank 100 and the degradation tank 200 are detachably connected. Adopting a modular design, the degradation tank 200 and the sedimentation tank 100 can be disassembled and transported separately, facilitating the disassembly of the pond tailwater treatment equipment into multiple modules for transport. This allows the pond tailwater treatment equipment to be pre-manufactured in the factory, and then transported to its destination for assembly for direct use, eliminating the need for construction and simplifying its application.

[0035] In some embodiments of this utility model, the pond effluent treatment equipment further includes a first connecting pipe 510, the two ends of which are detachably connected to a sedimentation outlet and a degradation inlet, respectively. This achieves a detachable connection between the sedimentation tank 100 and the degradation tank 200. The first connecting pipe 510 can be detachably connected to the sedimentation outlet via a flange, and the first connecting pipe 510 can be detachably connected to the degradation inlet via a flange. The sedimentation tank 100 can be positioned above the degradation tank 200 to promote water flow from the sedimentation tank 100 to the degradation tank 200. Alternatively, a pump can be installed on the first connecting pipe 510 to further promote water flow from the sedimentation tank 100 to the degradation tank 200.

[0036] In some embodiments of this utility model, the pond tailwater treatment equipment further includes an adsorption tank 300, which has an adsorption inlet and a third outlet. The third outlet is used to drain water into the pond and is connected to a third drainage pipe 630. The degradation tank 200 has a degradation outlet, which is connected to the adsorption inlet. The control system includes four switching valves, two of which are located at the degradation outlet and the second outlet, respectively. The switching valve located at the degradation outlet is called the third valve 430, and the switching valve located at the second outlet is called the fourth valve 440. The adsorption tank 300 is used to adsorb heavy metal ions and other harmful substances in pond effluent. The adsorption tank 300 is a conventional component in this field, and its specific structure will not be described in detail here. After fish medicine is added to the pond, the staff can control the first valve 410 and the third valve 430 to open and control the second valve 420 and the fourth valve 440 to close. The pond effluent can pass through the sedimentation tank 100, the degradation tank 200 and the adsorption tank 300. In addition to removing particulate matter through sedimentation and organic matter through biodegradation, it can also remove other soluble harmful substances through adsorption, achieving a better purification effect.

[0037] In some embodiments of this invention, the degradation tank 200 and the adsorption tank 300 are detachably connected. The modular design facilitates the transportation of the pond effluent treatment equipment after it has been disassembled into multiple modules.

[0038] In some embodiments of this utility model, the pond effluent treatment equipment further includes a second connecting pipe 520, the two ends of which are detachably connected to the degradation outlet and the adsorption inlet, respectively. This allows for a detachable connection between the degradation tank 200 and the adsorption tank 300. Specifically, the second connecting pipe 520 can be detachably connected to the degradation outlet via a flange, and the second connecting pipe 520 can also be detachably connected to the adsorption inlet via a flange. The degradation tank 200 can be positioned above the adsorption tank 300 to promote water flow from the degradation tank 200 to the adsorption tank 300. Alternatively, a pump can be installed on the second connecting pipe 520 to further promote water flow from the degradation tank 200 to the adsorption tank 300.

[0039] In some embodiments of this invention, the control system includes a controller 820 and a monitoring instrument 810 for monitoring pond water quality indicators. The switching valves are solenoid valves, and the monitoring instrument 810 and the four switching valves are electrically connected to the controller 820. The controller 820 is configured to control the four switching valves to close or open based on the information obtained from the monitoring instrument 810. This allows the pond wastewater treatment equipment to monitor the pond water quality in real time and then activate the degradation tank 200 and adsorption tank 300 as needed, eliminating the need for personnel to operate the four switching valves and simplifying its use. Alternatively, the switching valves can be configured as proportional valves, and the controller 820 can be configured to control the opening degree of the four proportional valves based on the information obtained from the monitoring instrument 810.

[0040] In some embodiments of this invention, the monitor 810 includes a pH monitoring module, a permanganate index monitoring module, a suspended solids monitoring module, a total phosphorus monitoring module, and a total nitrogen monitoring module. This allows for multi-angle monitoring of pond water quality, avoiding interference from accidental factors and accurately controlling the four switching valves.

[0041] In some embodiments of this utility model, the sedimentation inlet is provided with a water intake pipe 700, and the water intake pipe 700 is equipped with a water pump. This facilitates the intake of water from the pond.

[0042] In some embodiments of this invention, the monitoring instrument 810 is located on the side of the water intake pipe 700 away from the sedimentation inlet. The monitoring instrument 810 collects water from the water intake end of the water intake pipe 700 for water quality analysis, avoiding interference from the treated water to the monitoring of the pond water.
