A method for purifying lake water with aeration and oxygenation

Abstract

The invention discloses a purification method of an aeration oxygenation type lake water body. The method comprises the following steps of (1) sewage filtering treatment; (2) sewage aeration treatment; (3) sludge flocculation and separation; (4) sludge sterilization treatment. The method provided by the invention has the advantages that the structure is simple; the practicability is high; the overall treatment is performed on the lake sewage through a filtering pool, an aeration pool, a precipitation pool and a sterilization pool; the sewage treatment quality is effectively improved; meanwhile, the dissolved oxygen content in the sewage is increased through the aeration pool, so that the self purification capability of the lake water is improved. The technical method has the advantages that the work efficiency is high; the energy consumption loss is low; the sewage treatment effect is obvious; the comprehensive utilization rate is effectively improved.

Description

technical field [0001] The invention relates to a purification method of an aeration and oxygenation type lake water body. Background technique [0002] In the formation and development of cities, lakes, as important resources and environmental carriers, are related to urban survival, restrict urban development, and are important factors that affect urban style and beautify the urban environment. Urban lakes have various ecological functions such as water supply, green space, environmental protection, transportation and cultural education. It shows irreplaceable significance in the construction of cities and the expansion of urban space development. With the acceleration of urbanization in our country, the development and utilization of land on both sides of the lake has damaged the function of urban lakes, and a large amount of industrial and domestic sewage has been directly discharged into the river without treatment, resulting in lake water pollution, deterioration of w...

Problems solved by technology

In the existing technology, simple filtration and disinfection are generally used for the treatment of lake sewage. Although the water quality of the lake can be alleviated to a certain extent in the short term, it is not conducive to the long-term treatment of the lake water quality.

Moreover, purely using filtration and disinfection to treat sewage, the quality of final sewage treatment is average.
