The input end of the sewage pipeline 113 is arranged on the second water inlet 117, and the input end of the drainage pipeline 114 is arranged on the first water inlet 116.

[0042] Specifically, the output end of the filtering pipeline 112 and the input end of the sewage pipeline 113 can be connected to the second water inlet 117 through a three-way pipe; and the output end of the flushing pipeline 111 and the input end of the drainage pipeline 114 are connected to the first water inlet 116 through a three-way pipe. In this way, the entire source water treatment system is more simple, the space layout is optimized by pipeline arrangement, pipeline redundancy is reduced, and the operation efficiency of the system is improved.

[0043] As shown in Figure 1 the embodiment also includes a sewage collection tank 13, and the output end of the sewage pipeline 113 is arranged on the input end of the sewage collection tank 13. The sewage collection tank 13 is used for collecting sewage after flushing the filter cylinder 11, so as to prevent pollution of the breeding environment. The sewage can be periodically discharged or used for irrigation after being treated by sedimentation in the sewage collection tank 13, so as to realize resource recycling.

[0044] As shown in Figure 2As shown, a communication pipe 115 is arranged between the sewage pipe 113 and the drain pipe 114 in the embodiment, and a fifth valve 1151 is arranged on the communication pipe 115.

[0045] As shown in the drawings, Figure 1 In the embodiment, a control cabinet 14 is further included, and the first valve 1111, the second valve 1121, the third valve 1131, the fourth valve 1141 and the fifth valve 1151 are electrically connected to the output end of the control cabinet 14. The control cabinet 14 can be a PLC control cabinet 14, and the valves can be electric valves. The opening and closing states of the valves are automatically adjusted by the control cabinet 14 to realize the function of system timing self-cleaning. The control cabinet 14 can also be electrically connected with the water pump 10 to control the water pump 10 to adjust the water flow and pressure energy consumption.

[0046] As shown in the drawings, Figure 1 In the embodiment, a plurality of filter cylinders 11 are arranged, and the drain pipe 114 of one filter cylinder 11 is connected with the flushing pipe 111 of the next filter cylinder 11. The filter cylinder 11 is provided with filter fillers, which are quartz sand or zeolite or activated carbon.

[0047] Specifically, the plurality of filter cylinders 11 can realize multi-stage filtration, gradually improve water quality, and ensure that the water for aquaculture meets high standards. The filter fillers in the plurality of filter cylinders 11 can be the same or different, and can be flexibly configured according to water quality requirements. Preferably, the filter cylinder 11 is provided with three quartz sand, zeolite and activated carbon, forming a multi-level filtration system. The quartz sand can intercept suspended solids, organic matter, colloidal particles, microorganisms, chlorine odor and part of heavy metal ions in source water; the zeolite can intercept ammonia nitrogen, total phosphorus, lead and hexavalent chromium metal in source water; and the activated carbon can further intercept suspended solids, organic matter, colloidal particles, microorganisms, chlorine odor and part of heavy metal ions. Thus, through multi-level filtration, impurities and harmful substances can be effectively removed to ensure that the water quality is pure and stable.

[0048] As shown in the drawings, Figure 1As shown, the disinfection barrel 12 in the embodiment is an ozone disinfection barrel 12, and an ultraviolet sterilization lamp 121 is arranged in the disinfection barrel 12. The material of the disinfection barrel 12 is stainless steel 304, which has the characteristics of high strength and corrosion resistance, and can directly place the ultraviolet sterilization lamp 121. The disinfection barrel 12 is sterilized by ozone and ultraviolet rays. Ozone can quickly kill common bacteria and pathogens in the breeding environment through strong oxidation, such as Vibrio anguillarum, furuncle bacteria, Escherichia coli, and Pseudomonas aeruginosa. The wavelength of ultraviolet rays is 253.7nm, which can directly destroy the DNA / RNA structure of bacteria, viruses, parasites and other microorganisms, making them lose the ability to reproduce and die. It can also kill common pathogens such as Vibrio, Escherichia coli, and baculovirus. In addition, the ultraviolet sterilization lamp can inhibit the photosynthesis of algae, solve the problem of "green water" in the water body, and ensure the clarity and transparency of the water quality; it can promote the oxidation and decomposition of suspended organic matter in water (such as fish manure and leftover feed), reduce the odor of the water body, and the ultraviolet sterilization lamp 121 will not produce toxic side effects and will not affect the beneficial bacteria, effectively protecting the ecological balance of the breeding environment.

[0049] As shown in the Figure 1 The output end of the disinfection barrel 12 is provided with a water conveying pipeline 122 connected to the water storage pool 15, and the water conveying pipeline 122 is arranged in a "n" shape. A ball valve switch 1221 is arranged on the water conveying pipeline 122 to realize the opening and closing control of the water conveying pipeline 122. The filtered water is discharged from the disinfection barrel 12 into the water storage pool 15 by opening the ball valve switch 1221. The horizontal pipeline of the "n" shaped water conveying pipeline 122 is flush with the water level of the disinfection barrel 12, and the vertical pipeline extends to the bottom of the water storage pool 15. In this way, the flow rate and discharge speed of the water in the disinfection barrel 12 can be slowed down, and the residence time of the source water in the disinfection barrel 12 can be increased to ensure sufficient disinfection and sterilization.

[0050] As shown in the Figure 1 The disinfection barrel 12 and / or the water conveying pipeline 122 are provided with a sewage discharge device 123 for removing organic foam. The organic foam generated in the disinfection barrel 12 is discharged into the sewage collection pool 13 through the sewage discharge device 123, so as to avoid pollution of the water quality and ensure the purity of the water quality.
