The water body in the biochemical pool 9 is continuously aerated by the linkage blower, so that the biochemical filler in the fluidized bed pool floats up and down, and a beneficial dissolved oxygen condition is created for the biochemical reaction of the cultured flora, thereby realizing the degradation and conversion of the soluble pollutants.
The effluent of the biochemical pond 9 enters an ultraviolet pond 10 for disinfection treatment, bacteria, viruses and algae in the water are killed by ultraviolet rays, hydroxyl free radicals with strong oxidability are cooperatively generated by AOT photocatalytic disinfection equipment, the water is further disinfected and killed efficiently, the disinfected water can be used as cultivation water and re-enter the cultivation pond 1, and therefore the purpose of recycling cultivation water is achieved, and the purposes of saving energy and water are achieved.
The invention can not only recycle the culture water, but also supply oxygen-enriched water to the culture pond through devices such as a high-pressure oxygen supply tank, a water supply pump and the like, thereby ensuring the good living environment of aquatic animals in the culture pond.
