2016—2021年上海市杨浦区黄浦江流域水质变化与污染特征分析

摘要:
为全面了解并跟踪上海市杨浦区黄浦江流域的水质情况,于2016年1月—2021年12月对杨浦区黄浦江流域的6个监测断面的地表水质量进行调查。采用单因子污染指数分析法和水质综合污染指数分析法,探究了杨浦区内黄浦江流域水质的污染变化特征。结果表明,自2017年杨浦区开展河道整治以来,流域总体水质明显改善,出口水质从重度污染提升到良好水平;居民区密集的虬江断面水质相对较差,后续需加强对虬江流域的污染排放管理;水质污染特征分析结果发现河道的主要污染物种类从氨氮(NH3-N)转换为总磷(TP),说明河道整治提升了河道的自净能力,水质改善效果显著;水质在非汛期优于汛期,气温、降雨、泵站放江和污水排放是影响水质的主要原因。

Abstract:
In order to track and get full knowledge of the water quality of Huangpu River in Yangpu District of Shanghai, the water quality data of 6 monitoring sites from 2016 Jan. to 2021 Dec. were collected. Through the analysis of the annual average concentration of individual pollutants and the integrated pollution index, the variation characteristics of water quality were cleared. The results showed that after the river remediation work of Yangpu District in 2017, the water quality at the outlet of the Huangpu River Basin has been improved greatly. The results of the 6 sites showed the sections with dense residential areas had a huge impact on water quality, so the pollution situation in the Qiujiang River needs to be further strengthened in the follow up management. The main pollutants in the river converted from NH3-N to TP, indicating that the river remediation improves the self purification ability of the river, which had a remarkable influence on the water quality. The water quality in the rain season was inferior than others. Temperature, rainfall, pumping station discharge and sewage discharge were the main reasons for affecting the water quality.
