With the increasing world population, water resources can quickly become a factor for limiting a plurality of industries, the nutrition cost required by food production is further increased, the demand of southeast Asia countries on high-quality water products is greatly increased, the current situation of the fishing industry is kept or the fishing industry is in a descending trend, and the cultured aquatic products occupy the main market. Meanwhile, the water cost of agriculture, especially aquaculture industry, is increased, the environmental pressure is increased, and the biggest challenge of 21 st century agricultural production is to produce more than 3 times of products by using less resources. World bank global fishery program-2030 fishery project preliminary: the world aquaculture amount must be increased by 100% in 10-15 years in future to meet the increasing demand of people on aquatic products.
Pond culture, reservoir culture and riverway cage culture are always traditional aquaculture modes in China, but the cage culture is generally suitable for wide water areas of riverway surfaces, and the yield of the pond culture per unit area is much lower than that of the cage culture. In recent years, due to the pressure of national ecological environment protection, the current river reservoir net cages completely forbid the cultivation, advocate green environment protection and intensive cultivation, and the pond cultivation also conforms to the mode of aquaculture which is the dominant cause. However, due to the pressure of national ecological environment protection, the traditional pond culture faces the pressure of strict standard discharge of tail water and tense utilization of water resources, and further development of the aquaculture industry in China is restricted to a certain extent. Therefore, how to reduce tail water discharge in the freshwater pond culture process is a key problem of sustainable development of freshwater aquaculture industry; the low-carbon, high-efficiency and environment-friendly circulating water aquaculture mode and the waste recycling are development directions of modern fresh water aquaculture industry. Therefore, a cultivation tail water treatment recycling technology is needed, and some cultivation tail water treatment recycling technologies are also reported in published documents, such as:
