镇江市老城区生活污水水质特征及排放规律研究

Research on Zhenjiang Domestic Sewage Quality and Emission Rules

镇江市老城区排水系统落后,主要以合流管网为主,区域内居民生活污水已成为镇江市水环境污染的重要来源之一,对该区域内居民生活污水水质特征和污染排放规律进行研究,不但有助于正确认识、科学把握城市面源污染特征,还有利于污染控制对策的制定和治理工程的开展。选择镇江市老城区典型合流制管网系统——黎明河溢流口,采用定点动态采样的方法,进行该区域生活污水水质特征和污染排放规律研究。研究结果表明,研究区域内各月的COD、TN、TP和SS的逐时变化规律具有各自的相似性。

Drainage system of the old urban in Zhenjiang is backward,mainly in the combined network and sewage pollution from residents living of the area has become one of the important sources of water pollution,so research on the character of sewage quality and pollution emission rules of the region,not only contributes to the correct understanding and scientific grasp the city non-point source pollution characteristics,but also the stipulating of pollution control countermeasures and development of treatment project.This research chooses the old urban of Zhenjiang,a typical combined network system—Liming River overflow port,using fixed-point dynamic sampling method for the regional sewage water quality and pollution emission study.The results show that hourly variation laws of COD,TN,TP and SS of every month in sewage from the study area have respective similarity.
