For nearly thirty years, the population of lakes increases rapidly along the coast, and untreated domestic sewage is discharged directly into the lakes. Along with the rapid development of economy and society, the industry is driven to rapidly develop, a large amount of untreated or unqualified industrial sewage is directly discharged into the lake, and the phenomenon of illegal lake filling occurs, so that the water environment of the lake is seriously polluted. Moreover, most of China lakes are closed inland lakes, and the self-cleaning capability of water bodies is limited, so that the water quality is continuously deteriorated, and the functions are seriously atrophic.
Through investigation and research, the polluted lake water mainly comprises ammonia nitrogen, total phosphorus, biochemical oxygen demand, chemical oxygen demand and other indexes exceeding standards. Therefore, the main root of lake pollution is caused by the fact that industrial wastewater and domestic sewage containing a large amount of pollutants such as nitrogen, phosphorus and the like are discharged into the lake in a large amount, so that abnormal propagation of certain characteristic algae is caused, the transparency of water is reduced, dissolved oxygen is reduced, the water quality is poor, and the phenomenon that microorganisms, organisms and plants of natural ecology of fishes and other lakes die in a large amount is caused. Algae and plant residues consume more dissolved oxygen when they decay and decompose, and after the dissolved oxygen is consumed, the water body is finally odorized, degenerated and cloudy. If the lake with serious pollution is not treated in time, the transparency can be rapidly reduced, so that the irradiation intensity and dissolved oxygen of sunlight in the lake water body can be rapidly reduced, the pollution mechanisms can lead to a vicious circle to accelerate the pollution of the lake, and the lake treatment is more difficult and more costly in the future, and even the lake treatment is deteriorated to the extent that the lake treatment is very difficult.
