| 摘 要： | 基于在线监测与人工水质相结合的方法,通过大量背景数据的收集,制定了系统化的监测方案,实现了区域内各污染物负荷的定量化分析工作。结果表明:在提质增效的"挤外水"中,污水管道入渗地下水的去除可将污水厂水质浓度提高36.01%;工企业污水的污染物负荷贡献率较低,部分企业需在预处理后继续排入污水处理厂;"收污水"中,对水厂浓度提高影响较大的是城乡接合部散排污水,全部纳管收集后,污水厂水质浓度将提高30.30%。同时,雨水管网混流污水与过河管道漏失污水虽对污水厂水质浓度的提高影响较小,但也会带来水体污染的危害,仍需进行改造纳管。

| Abstract: | Based on the combination of online monitoring and artificial water quality, this paper formulated a systematic monitoring scheme through collecting background data, and realized the quantitative analysis of pollutants load in the region. The results showed that in the "squeezing out water" working part of improving quality and efficiency strategy, the removal of groundwater infiltrated by sewage pipelines can increase the water quality concentration of sewage plants by 36.01%, playing an important role; the contribution rate of pollutant load of sewage from industrial enterprises was low, and some enterprises needed to continue to discharge into the sewage treatment plant after pretreatment; in the "sewage collection" working part, the scattered sewage in the urban-rural fringe areas had a great impact on the increase of water plants’ inlet concentration. After all the sewage is collected in pipes, the pollutants’ concentration of the sewage plant inlet will increase by 30.30%. At the same time, although the mixed flow sewage of rainwater pipe network and the leakage sewage of river crossing pipeline have little impact on the increase of the inlet pollutants concentration of sewage plant, the pipe still needs to be modified and even reconstructed. |
