Description

Closed circulating water culture pond Technical Field The utility model relates to the technical field of aquaculture devices, in particular to a closed circulating water aquaculture pond. Background With the vigorous development of the aquaculture industry, the defects of the traditional open aquaculture pond are increasingly prominent. Under the traditional cultivation mode, the cultivation water body is generally directly communicated with the external environment, pollutants such as residual baits, feces and metabolic waste generated in the cultivation process are directly discharged to surrounding natural water bodies without being effectively treated, a large amount of organic pollutants and nutrient substances such as nitrogen and phosphorus enter the water body, eutrophication of the water body is easily caused, the problems of excessive algae propagation, water quality deterioration and the like are caused, the ecological balance of water is seriously damaged, and the survival of surrounding aquatic organisms and the water use safety of human beings are threatened. Meanwhile, the open cultivation needs frequent water change to maintain water quality, water resource waste is serious, and in the water resource shortage area, the cultivation mode further aggravates water contradiction. In addition, the traditional culture pond has simple filtration and purification facilities, is difficult to effectively remove harmful substances in water, has unstable water quality, influences the quality and the yield of aquatic products, and restricts the sustainable development of the aquaculture industry.
