Abstract
Urban sewage treatment has always been an important factor affecting the quality of urban environment.With the acceleration of urbanization,the amount of sewage discharge continues to increase,and the types of pollutants are becoming increasingly complex,which brings enormous pressure to urban environmental protection.Currently,urban sewage treatment in China is facing problems such as aging pipelines,insufficient treatment capacity,redundant construction,and high operation and maintenance costs.Therefore,efforts should be made to strengthen regulatory construction,promote the utilization of sewage resources,enhance the main responsibility of pollutant producing units for governance,establish long-term mechanisms for sewage treatment,etc.,improve urban sewage collection systems,expand and upgrade the treatment capacity of sewage treatment plants,promote the resource utilization of sludge and recycled water,and minimize pollutant emissions.Ultimately,a technologically advanced,scientifically managed,and economically reasonable sewage treatment system is established,effectively protecting the urban environment.关键词
