Abstract:
After more than 40 years of research and practice, King County’s combined sewer overflow (CSO) control has formed a relatively complete technical standards system and supervision and management system, and achieved good results. In many aspects, it is at the leading level in the United States. King County integrates the wastewater treatment plant, the CSO storage and treatment plant, and the sewer overflow outfall into one discharge permit for management. The “plant-network” discharge standard and process are designed for receiving the information of water quality, matching the wet and dry weather operating conditions. The “cost-effectiveness” of pollutant emission achieved better performance. In order to provide reference for the practice of urban CSO control engineering in China, the implementation and operation of the CSO control project in the watershed of the West Point wastewater treatment plant, as well as the discharge standards and compliance were introduced.
