Abstract
With the rapid development of urbanization, the production of urban sewage increases sharply, and its treatment and discharge become an urgent environmental problem. As a key water treatment facility, the emission reduction effect of urban sewage treatment plant is very important to environmental protection. This paper explains related concepts, including the basic principles of sewage treatment, scientific concepts of carbon, nitrogen and phosphorus removal, and sewage pollutant load and discharge standards. The current status of urban sewage treatment is further analyzed, including the production volume and characteristics of sewage, existing treatment technology and facilities, and the existing problems and challenges are pointed out, such as treatment efficiency, energy consumption and operating costs, sludge treatment and disposal problems and the pressure of upgrading discharge standards. This paper puts forward specific emission reduction strategies, involving optimization of treatment process, energy recovery and utilization, intelligent management, strengthening supervision and public participation, etc., and gives an analysis of typical emission reduction cases of urban sewage treatment plants, including emission reduction strategies and implementation process, experience and enlightenment in the cases. This paper provides the scientific basis and practical guidance for the emission reduction of urban sewage treatment plants, which is of great significance for promoting the green transformation of sewage treatment industry and promoting environmental protection and sustainable development.
