Description
Technical Field
The invention relates to the field of water purification, in particular to a method for purifying micro-polluted water body by intelligently culturing pearl mussels and microorganisms in a synergistic manner.
Background
With the rapid development of the economy of China, the problem of water pollution in rural areas is increasingly serious. In the field of planting, with the decrease of the cultivated land area, farmers use a large amount of fertilizers and pesticides in pursuit of the yield of crops. Excessive and unreasonable use of chemical fertilizers and pesticides can cause soil hardening, water and soil loss and the like, untreated tail water of the rice field pollutes surface water and underground water, particularly the tail water of the rice field in the polder area of the nested lake, which is applied with chemical fertilizers and pesticides in large quantity, is discharged through a drainage and irrigation station in rainy season, so that the water quality of the water body in the nested lake is directly influenced, and the discharged water quality is influenced by the discharge of a river Jihuai channel. Tail water in the aquaculture process is poor in quality and is discharged without treatment, so that the surface water quality is seriously affected; rural residents live scattered, domestic sewage is discharged randomly, due to the fact that the rural residents live scattered, parts of the rural residents are remote, supervision departments are difficult to monitor, the phenomenon of rural black water and grey water is serious, the requirements of people on animal husbandry are increased in breeding industry, most of domestic livestock and poultry breeding is located in urban and rural junctions or rural areas, and the nutrient returning rate of livestock and poultry manure in China is lower than 50%. Livestock and poultry manure which is not safely treated is randomly stacked, and pollutes surface water and underground water around the farm along with rainwater runoff.
Meanwhile, the conventional mode of freshwater pearl culture is a water fertilizing technology to improve the pearl yield, a large amount of organic fertilizer or chemical fertilizer is put into water areas such as a fishpond or a small lake to enable the freshwater mussels to grow fast, the pearl culture period is short, the pearl yield is improved, but a large amount of organic matters on the bottom layer are accumulated and the water body is eutrophicated, so that the water body pollution, the mussel diseases and the fish diseases frequently occur. In order to maintain the normal operation of production, culturists increase the yield of freshwater mussels and pearls by enlarging the production scale and improving the cultivation density, however, the cultivation of the freshwater mussels with high density causes the shortage of bait organisms, the growth of the freshwater mussels is slow, the physique is poor, and in order to meet the ingestion requirement of the freshwater mussels, farmers put in a large amount of organic fertilizers, so that the environment for cultivating pearls is worsened, diseases are frequent, and a vicious circle with higher density and lower benefit is formed.
