Specific: firstly, the culture water to be treated is pumped from the center of the bottom of the culture pond 1 through a first water pump 21 and then flows into an electric field sterilizing device 3 through a water inlet pipe 22, the electric field sterilizing device 3 electrolyzes salt-containing seawater to generate hypochlorous acid, so that sterilizing treatment of various bacteria is realized, meanwhile, the strength of sterilizing and decomposing organic matters of a circulating purification system can be controlled by adjusting the current, and the method is efficient and convenient;
then, the sterilized aquaculture water is led into the protein separation device 4, a second water pump 441 pumps high-speed water flow into the separation tank 41, and air led in through an air inlet pipeline 444 is matched, so that the water in the separation tank 41 rapidly rotates to generate bubbles, and the bubbles carry a large amount of organic matters to float upwards for collection and flow to a collection tank through a blow-off pipe 43 to wait for further treatment;
finally, the treated aquaculture water is discharged from the return pipe 5 back to the aquaculture pond 1, and the first water pump 21 pumps water from the center of the aquaculture pond 1 to repeat the above operation, thereby completing a working cycle.
The electric field sterilizing device 3 is arranged to electrolyze the salt-containing seawater to generate hypochlorous acid, so that sterilizing treatment on various bacteria is realized, and the effect of separating protein by the protein separating device 4 is matched, so that the water quality in the culture pond 1 is effectively and circularly purified, and the sterilizing effect is obvious.
