- Abstract:
- In order to provide theoretical support for ensuring the stable operation of the sewage system and increasing the control of sewage overflow, the problems existing in the pollution control of sewage overflow in Chongqing are analyzed and summarized. The main causes of sewage overflow in Chongqing including rainwater, river water and other water entering the sewage system, sewage pipe network siltation and blockage, the difficulty of the interception multiple to meet the increasingly strict overflow control requirements, and regional overdevelopment. The blind interception of source control, the contradiction between actual overflow and strict environmental protection control, unclear overflow control standards and difficult implementation of overflow control measures are the main obstacles in overflow pollution control. Some suggestions are put forward to carry out overflow pollution control, including standardized management of overflow outlets, scientific guidance of overflow pollution control standards and special actions for overflow pollution control.
