Abstract
China’s urban sewage treatment developed rapidly, but there are many common problems. In the form of online questionnaire, 1100 people were randomly selected as sample data for description analysis. Based on quantitative research methods on China’s drainage and sewage treatment from 1978 to 2019 and the literature research and information integration of related books and materials, this article discusses the commonalities in urban sewage discharge standards, sewage treatment, and effective sludge treatment and recycling. Descriptive research is carried out on the problem, and due to the current main contradiction in sewage treatment, it is converted to the effective removal of nitrogen and phosphorus organic matter. Then, anaerobic ammonia oxidation is introduced and its scientific and technological prospects are prospected, hoping to provide supportive reference for related research researchers.
