It should be understood that the high-efficiency nozzles 83 release ozone micro-nano bubble water. The ozone micro-nano bubble is sucked into the planting area and ozone by the multiphase flow gas-liquid pump, and the gas-liquid two-phase is fully dissolved and reaches high pressure saturation under high pressure conditions in the pump to produce dissolved gas water. The ozone micro-nano bubble water is released to the electrolytic tank through the high-efficiency nozzles, and the ozone concentration is not too high to avoid affecting the fish when input into the breeding pond, so that the oxygen molecules in the water in the electrolytic tank can be increased.

[0042] Further, the fish and plant symbiotic system circulating water body purification treatment device further comprises a backwashing circulating pump 22, a first circulating pipe 23 and a second circulating pipe 24, wherein the backwashing circulating pump 22 is arranged outside the microfiltration machine box body 2, one end of the first circulating pipe 23 is connected with the bottom end of the containing cavity, the other end of the first circulating pipe 23 is connected with the input port of the backwashing circulating pump 22, one end of the second circulating pipe 24 is connected with the output port of the backwashing circulating pump 22, the other end of the second circulating pipe 24 penetrates the top end of the containing cavity, and a plurality of flushing nozzles 241 are arranged in the other end of the second circulating pipe 24 in the containing cavity, and the other end of the second circulating pipe 24 is above the filtering rotary drum 4. It should be understood that when the filtering rotary drum 4 needs to be cleaned after filtering the impurities in the sewage, the backwashing circulating pump 22 can first suck the filtered liquid in the containing cavity into the backwashing circulating pump 22 through the first circulating pipe 23, and then clean the filtering rotary drum 4 through the plurality of flushing nozzles 241 on the second circulating pipe 24, and the flushing nozzles 241 spray high-pressure water flow, which is enough to spray the particles stuck in the stainless steel filter screen of the filtering rotary drum 4 back into the filtering rotary drum 4.

It should be understood that the first wire of the direct current power supply is connected with the plurality of anode plates in the electrolytic tank through the first branch wire, and the second wire of the direct current power supply is connected with the plurality of cathode plates in the electrolytic tank through the second branch wire.

[0045] It should be understood that the self-suction sewage pump 31, the transmission motor 21, the ozone generator 82, the multi-phase flow gas-liquid pump 81, the direct current power supply 71, the backwashing circulating pump 22, the flushing nozzle 241, the high-efficiency nozzle 83 and the electrode plate 9 in the present application can be realized by using the products in the prior art, and the principles and internal structures thereof will not be described here.

[0046] Specific working principle:

[0047] The sewage of the breeding pond 1 is sucked into the inside of the filter drum 4 located in the microfilter box 2 by the self-suction sewage pump 31, and the transmission motor 21 can drive the filter drum 4 to rotate through the first gear 211 and the second gear 41, so as to start filtering the sewage sucked into the filter drum 4. The filter holes and the stainless steel screen of the filter drum 4 can filter the particulate impurities (such as the feed residues after being eaten by fish and shrimp or the dead bodies of fish and shrimp). The filtered water is transported from the second pipe body 6 to the planting area 5 to provide nutrients for the hydroponic vegetables therein (the nutrients are obtained by decomposing ammonia nitrogen in the water into nitrite by bacteria, and then decomposing the nitrite into nitrate by nitrifying bacteria, and the nitrate can be directly absorbed and utilized by plants as nutrients). If the filter holes of the filter drum 4 are blocked by particulate matter and affect the filtering process, the backflushing circulating pump 22 can drive the first circulating pipe 23 to first remove a part of the filtered liquid in the receiving cavity of the microfilter box 2, and then the multiple high-pressure water jet nozzles 241 in the receiving cavity of the second circulating pipe 24 can spray water against the rotating filter drum 4, so that the particulate matter stuck in the filter drum 4 can fall into the drain pipe 25, so that the filter drum 4 can continue to work. The filtered impurities and other particulate matter can be discharged from the drain pipe 25. While the water is being filtered, the water in the planting area and the ozone generated by the ozone generator 82 are simultaneously sucked into the multiphase flow gas-liquid pump 81 and pumped into the electrolytic tank of the tank body 7 to generate ozone micro-nano bubbles. The high-efficiency nozzle 83 releases the ozone micro-nano bubble water into the electrolytic tank. In the electrolytic tank, the oxygen molecules generated by the rupture of the ozone micro-nano bubbles can directly oxidize and sterilize, and increase oxygen to meet the survival needs of fish and shrimp for water. Finally, the water can return to the breeding pond for aquaculture from the fourth pipe body 10. The water forms a closed loop between the breeding pond 1, the filter drum 4, the planting pond 5, and the electrolytic tank of the tank body 7, which not only saves water resources, but also greatly reduces the cost of aquaculture and vegetable cultivation, and reduces unnecessary expenses.
