摘要:
城市排水清污混合是导致污水处理厂进水浓度偏低的重要原因，准确判断清污混合的水质成分、锁定清污混合的主要位置是解决上述问题的关键。为此，建立了基于水质特征离子法的排水管网水质成分解析方法，并将其应用于案例城市，准确识别了排水管网各处水质成分、构成比例、沿程变化以及清污混合关键位置，发现地表景观水、工地基坑排水以及河道引水是该案例城市排水管道中清水的主要来源，这可有效指导后期的清污分离工程。
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.
