- Abstract:
-
The mixing of clean water and sewage in urban drainage system is an important reason for low influent concentration of wastewater treatment plants. The key to resolve the above problem is to accurately judge the composition of the mixing drainage water and locate the mixing position in the drainage network. A mixing drainage water composition analytical method based on water quality characteristic ion method was developed, and the method was applied in a case city to identify the drainage water composition, quantity proportion, content change and mixing positions in the drainage network. It was found that surface landscape water, foundation pit drainage and river diversion were the main sources of clean water in the urban drainage pipeline of the case city. The findings can effectively guide the later clean water and sewage diversion project and provide reference for other cities to solve similar problems.
