南水北调东线工程沿线污水处理厂尾水处置研究

Research on sewage disposal of wastewater treatment plants along East Route of South-to-North Water Transfer Project

为确保南水北调东线工程调水水质安全,沿线污水处理厂尾水不允许排入输水干线。要建设尾水排放的安全通道,必须将尾水无害化和资源化利用结合起来;提出了直接排放、深度处理、净化工程三种沿线尾水处置的途径。各地应结合实际情况,联合运用多种技术手段,寻求尾水综合利用的最优方案。

To ensure water quality safety in East Route of South-to-North Water Transfer Project, sewage water from wastewater treatment plants along the lines are not allowed be drained into East Route Project. Building safe passages of sewage must decontaminate and recycle the sewage water. It put forward three methods in this paper to disposal sewage, including direct discharge, advanced treatment and decontamination. Optimal sewage utilization plan relies on the use of variety technology according to local conditions.
