Abstract
Urbanization leads to the problem of sewage discharge, especially nitrogen and phosphorus pollution, which has a serious impact on water environment. This paper discusses the technical principle, present situation, problems and optimization strategy of nitrogen and phosphorus removal in wastewater treatment. Firstly, the paper analyzes the influence of nitrogen and phosphorus pollution and the research background, summarizes the technical status at home and abroad, and determines the goal of improving the removal efficiency. Then, the biochemical principle of nitrogen and phosphorus removal is explained in detail, and several common processes are introduced. The analysis shows that existing treatment plants face problems such as low efficiency, high cost and complex environmental impact. Therefore, the paper puts forward the optimization scheme, including the process transformation and the application of new technology, and emphasizes the importance of adjusting the operating parameters. This paper provides theoretical and technical guidance for the sewage treatment plant, and puts forward a feasible optimization scheme, which is of great significance to improve the treatment efficiency, reduce the cost and reduce the pollution.
