Background
Daily domestic sewage is mainly used by integrated sewage treatment equipment, and the so-called sewage treatment is a process for enabling the sewage to reach a certain index of discharge or purifying the water quality of the sewage in order to be reused. Along with the development of world economy and the enhancement of environmental protection consciousness of people, countries in the world have made higher requirements on the discharge standard of sewage, and the removal of nitrogen and phosphorus in the sewage can not be guaranteed to reach the standard through the conventional sewage treatment technology, so that the sewage treatment plant pays more and more attention to the nitrogen and phosphorus removal technology of the treated discharged sewage. As is known, the over-standard content of nitrogen and phosphorus in the water body is the main cause of water body eutrophication, not only causes a large amount of economic loss, but also causes environment damage which is difficult to estimate, a large amount of fishes die, and the water body smells and can be recovered or even not recovered in a long time. Along with the enlargement of urban scale, the discharge amount of urban sewage is increased year by year, and the existing biological treatment system must be modified to meet the requirements of denitrification and dephosphorization. At present, the common sewage treatment technology in China is still a biological technology.
Although the biological method is effective in treating sewage, the structure and the composition are complex, the factors needing to be controlled in the middle are strict, and the biological method is suitable for large-scale sewage treatment, but the biological method is not suitable for families with small sewage generation amount and needing to be frequently used, and the efficiency of large-scale integrated sewage treatment equipment cannot meet the use requirement of the families.
