- Abstract:
- In order to solve the problems of external water intrusion, frequent overflow pollution and low operation efficiency in urban drainage systems in China, in this paper, the mature concept of district metered area (DMA) in the water supply network is introduced into the drainage system. The complex drainage system is divided into different levels of management areas and water quality and quantity monitoring and measurement areas. It provides support for quantitative diagnosis of key problems in different areas and establishment of assessment standard system. Taking a sewage plant service area in H city as an example, five first-level management areas and five independent measurement areas were divided, and 92 days of continuous monitoring showed that this method can effectively identify the spatial and temporal characteristics of external water intrusion in different areas, among which the problem of Mengxi pumping station area is the most prominent. The research shows that the DMA divided area of drainage network can significantly improve the management efficiency of drainage network, which is of great value and significant to promote the fine management of drainage system in China.
