[0012] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0013] In the attached diagram, all identical reference numerals refer to the same components.

[0014] like Figure 1-2 As shown, this utility model provides a water purification device for fish ecological aquaculture ponds. The main body 1 of the device adopts a vertical layered structure, consisting of a filter tank 2, a sterilization tank 4, and a disinfection tank 6 from top to bottom. The cylindrical filter tank 2 is sealed to the top of the fixed box 3 by a flange. A detachable filter screen 203 is installed at the connection between the two. The filter screen 203 is made of 304 stainless steel and has a pore size of 0.5mm. The fixed box 3 is divided into two chambers by a partition. The upper chamber is the sterilization tank 4, and the lower chamber is the disinfection tank 6. The two chambers are controlled by an electric control valve 5.

[0015] A stirring assembly is horizontally mounted through the center of the top of the sterilization tank 4. The drive motor 403 of this assembly is fixed to the outer wall of the fixed box 3 by bolts, and its output shaft passes through the inner cavity of the sterilization tank 4 via a sealed bearing. Three sets of propeller blades 405 are welded axially to the surface of the stirring shaft 404. Each set of blades 405 is distributed in a 120° circle, and the angle between the blades and the axis is 45°. The rectangular observation window on the side wall of the sterilization tank 4 is made of tempered glass, and the surface is etched with volume scale lines from 0 to 50L.

[0016] A cylindrical storage tank 401 is fixed to the top of the fixed box 3 by a bracket, and a solenoid valve is installed at the outlet of the feeding nozzle 402 to control the amount of nitrifying bacteria added.

[0017] The inner wall of the disinfection tank 6 is symmetrically equipped with ultraviolet disinfection lamps 601, each with a power of 36W and a wavelength of 253.7nm. The surface of the lamp tube is coated with a quartz glass protective layer. A submersible water pump is fixed to the bottom of the disinfection tank 6 by bolts. The water pump inlet is equipped with a stainless steel filter cover, and the water outlet is sealed to the water outlet pipe 7 through a pagoda connector. The end of the water outlet pipe 7 is equipped with a union elbow for connecting to external pipelines.

[0018] At the same time, the solid impurities trapped by the filter screen 203 can be cleaned by opening the top cover 201, or the filter screen 203 can be disassembled and replaced.

[0019] In actual operation, the water from the aquaculture pond is injected into the filter tank 2 through the inlet pipe 202, and solid impurities are trapped by the filter screen 203. The water after preliminary filtration enters the sterilization tank 4 through the control valve 5. At this time, the storage tank 401 adds nitrifying bacteria preparation according to the preset program. The drive motor 403 drives the stirring shaft 404 to rotate at a speed of 120 rpm, so that the water and the bacteria preparation are fully mixed and carry out the biochemical reaction. After the biochemical treatment is completed, the control valve 5 is opened to allow the water to flow into the disinfection tank 6. The ultraviolet lamp group is started for terminal disinfection. At the same time, the water pump returns the treated water to the aquaculture pond through the outlet pipe 7 at a flow rate of 8 m³ / h.

[0020] This utility model is a water purification device for fish ecological aquaculture ponds. By integrating a three-stage purification system of physical filtration, biochemical treatment, and ultraviolet disinfection, it achieves gradient purification of the aquaculture water, significantly improving water purification efficiency. The layered tank structure, combined with the control valve 5, allows for flexible adjustment of the treatment process according to water quality conditions, ensuring sufficient biochemical reaction time for nitrifying bacteria while ensuring reliable ultraviolet terminal disinfection. The synergistic design of the storage tank 401 and the stirring component enables more precise addition and more uniform mixing of biological agents, effectively inhibiting the reproduction of harmful bacteria and reducing the intensity of manual operation while ensuring the ecological safety of the aquaculture water.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
