Technical Field
The invention relates to the technical field of sewage treatment, in particular to a tail water treatment system for freshwater pond culture.
Background
At present, the freshwater aquaculture in China is mainly pond aquaculture, along with the rapid development of the aquaculture industry in China, the scale and the mode of the aquaculture are changed, the traditional aquaculture is changed into intensive and high-density aquaculture, but because the water body is emphasized to be utilized to the maximum extent, many problems and disadvantages are accompanied while pursuing high yield as the center, for example, the environmental pollution of aquaculture water areas is worsened.
The adverse effect of fresh water pond culture on the water area environment mainly comprises the following four aspects: firstly, the pollution is caused by excessive bait feeding due to excessive residual bait caused by improper feeding method or poor bait quality. The second is contamination caused by the accumulation of certain chemical agents. The use of chemicals in aquaculture can cause pathogens to generate drug resistance and kill beneficial microorganisms in water, secondary pollution is generated, and water ecological imbalance is caused. And thirdly, the culture tail water is changed, such as water quality control, water changing by fishing and the like, and the culture tail water is directly discharged without being purified, so that the external environment is polluted. Fourthly, due to the lack of culture layout and culture mode guided by the culture ecological theory, relevant ecological regulation and control and other technologies, the ecological balance of the water area is seriously damaged. If the tail water discharge amount of the cultivation is large and the tail water is unreasonably treated, the tail water pollution is increasingly serious. At present, the concept of 'green development of aquaculture' is greatly advocated in China, the water environment is protected, and the construction, application and popularization of a culture tail water treatment system are increasingly important and urgent.
