Abstract:
To enhance the operational efficiency of the combined sewer overflow pollution control system and continually improve water environment quality, the drainage facilities related to overflow pollution control and environmental impact indicators caused by overflow pollution were selected in line with upper-level policies such as black and odorous water treatment and urban wastewater treatment for quality and efficiency improvement. Furthermore, an index system for evaluating the overflow pollution control system was proposed and an effectiveness evaluation method based on fuzzy comprehensive evaluation was established. Simultaneously, the efficacy of the overflow pollution control system was assessed using the drainage area of the northern part of Dianchi basin as a case study. Based on the evaluation results of each parameter, the overall operational efficiency of the overflow pollution control system in the specified area was suboptimal, and the assessment outcomes were not promising, indicating a need for enhancement in current facility efficiency. The results of the efficiency evaluation could help identify the shortcomings in overflow pollution control within the area, clarify key points for controlling overflow pollution, and support improvements to the local overflow pollution control system.
