上海海域污染源分析及控制对策

Analysis of pollutant sources in Shanghai Sea and control countermeasures

为了研究陆源污染对上海海域的影响,分析长江入海污染物通量的季节变化、黄浦江与长江对上海海域污染的贡献率、上海海域主要污染物的时空分布特征。结果表明:污染物随季节基本呈规律性变化,长江入海污染物对海域污染的贡献远大于黄浦江,长江和黄浦江对上海海域影响最大的污染物是TP;上海市主要污水排放系统对上海海域的N、P污染有很大贡献。最后提出控制上海海域污染形势的对策建议。

In order to study the influence of terrestrial pollutants on the Shanghai Sea,the seasonal change of pollutant flux entering the sea from the Changjiang River,the pollution contribution rate of the Changjiang River and the Huangpu River to the Shanghai Sea,the main pollutants of both rivers,and the spatial and temporal distribution of the main pollutants in the Shanghai Sea were analyzed.The results showed that pollutant fluxes generally changed with the season.The pollutant contribution of the Changjiang River was much larger than that of the Huangpu River.The main pollutant of both the Changjiang River and the Huangpu River was total phosphorus（TP）.The main wastewater discharge systems in Shanghai City were also the main sources of nitrogen（N） and phosphorus（P） to the Shanghai Sea.Finally,responsive control countermeasures are proposed.
