- Abstract:
-
With the acceleration of urbanization and industrialization, the discharge of municipal wastewater and the scale of wastewater treatment facilities in China have been increasing year by year.However, there are still problems in urban water environment management. By analyzing the development and current situation of municipal wastewater treatment facilities in China from 2002 to 2016, the infrastructure of wastewater treatment facilities have been basically completed, the contradiction between the end treatment infrastructure capacity and wastewater dischange has been alleviated, and the wastewater treatment facilities have left the remaining treatment capacity, so the construction of wastewater treatment facilities has changed from a stepped rapid growth model to a sustainable development model dominated by urban population change and urban construction. At the present stage, the main direction of urban water environmental pollution treatment has been transformed into solving the contradiction between the problems of pipe network and the current situation of water environment treatment. Insufficient length of pipe network, serious problem of misconnection of pipe network, infiltration of groundwater in pipe network, overflow of combined flow and construction of storage facilities are the main problems, which should be solved in future drainage system.
