摘要:
对2010—2014年三山港常州段NH3-N、TP污染现状及来源进行调查。结果表明,三山港常州段NH3-N、TP污染在时间上表现为逐年加重,在空间上表现为沿程递增;其中下游严庄桥断面附近污染最为严重,多种污染物在此处达到峰值。NH3-N、TP与特征污染物的相关性分析显示,三山港常州段NH3-N污染存在多种来源,而TP污染则与金属表面处理行业的磷化工艺有关,相关性>0.8。提出,NH3-N污染削减首先需要提高流域内污水接管率,从源头上减少污染物排放,同时减少化肥使用,降低农业污染贡献;工业污染是TP污染的主要来源,整治措施可一方面通过产业升级淘汰落后的高污染表面处理工艺,另一方面则通过加强监管,对企业污水处理设施“少开、不开”的行为加大处罚力度,有效减少企业的超标排放。

Abstract:
Sanshangang River is located in the east part of Changzhou City, it is an important diversion and drainage channel in the region, which plays a role of water channel for drawing water from Yangtze River to Taihu Lake in near future. Nitrogen and phosphorus pollution in Sanshangang River is very serious currently, temporal and spatial variation analysis of Sanshangang River from 2010—2014 in Changzhou section shows that nitrogen and phosphorus pollution increase in time scale of the yearly, while increment in the space along the river, and the section of Yanzhuang bridge is facing serious pollution, the concentration of various pollutants were in peak regularly. There are many sources of nitrogen pollution of Sanshangang River in Changzhou section and phosphorus pollution is related with phosphating processing of metal surface processing industry through correlation analysis of nitrogen and phosphorus pollutants with characteristic pollutant, which has a correlation coefficient of 0.8 or above.
