Research Progress in the Resource Utilization Technology of Tail Water From Urban Sewage Plants
With the acceleration of urbanization in China in recent years,urban sewage treatment has become a key research object in environmental protection.At present,the current situation of sewage treatment in China is worrying,with frequent problems such as low sewage treatment recovery rate,insufficient treatment level,and substandard tail water purification level.Urban sewage treatment systems urgently need technological upgrading and transformation.To ensure the effluent quality of wastewater treatment,it is necessary to strengthen research on the resource utilization technology of wastewater,promote the recovery technology of wastewater in China's wastewater treatment,and effectively enhance the secondary wastewater treatment process of urban sewage plants,in order to ensure that the effluent quality of sewage plants meets the national requirements for wastewater effluent quality testing standards.This article elaborates on the current research status of advanced treatment technology for urban sewage plant tail water from three aspects:physical and chemical methods,biological methods,and joint treatment technology,in order to provide reference for the technology process of resource utilization of urban sewage plant tail water.
