摘要
本研究旨在通过对海宁市2017年间地表水环境质量的监测及其评价,为其质量提高提供数据支持和参考依据。单因子评价结果显示,海宁市10个河流监测断面的高猛酸盐指数相对污染值(Ci)均低于1,均满足《地表水环境质量标准》(GB3838-2002)相应标准要求。溶解氧、总磷、氨氮和生化需氧量均未完全达标,其中总磷和生化需氧量平均Ci分别为1.03和0.92,是最主要污染指标。上塘河、洛塘河和麻泾港均能达到Ⅳ类水质要求,其他7条河流均未达到功能水质要求的Ⅲ类标准。内梅罗指数法评价结果显示,洛塘河和麻泾港PIP分别为0.68和0.69,其水质未受到污染,其余河段均受不同程度污染,但总体污染情况较轻。
This study aims to provide data support and reference for the improvement of surface water environmental quality in Haining by monitoring and evaluating the quality of surface water environment in 2017. According to the single factor evaluation method, the results of ten monitoring sections showed that the permanganate index relative pollution value （Ci） were less than 1, which have meet the requirements of Environmental Quality Standards for Surface Water surface （GB3838-2002）. The dissolved oxygen, total phosphorus, ammonia nitrogen and biochemical oxygen demand were not completely up to the standard. and the average Ci of total phosphorus and biochemical oxygen demand were 1.03 and 0.92 respectively, which were the most important pollution indicators. The Shangtang river, Luotang river and Majing port were all meet the requirements of Environmental Quality Standards for Surface Water surface （GB3838-2002） class IV, while the other seven rivers have not met the class III for functional water quality. According to the evaluation results of the Neimerow index method, the PIp of Luotang river and Majing port were 0.68 and 0.69, respectively. Which indicated that they were haven’t polluted. The rest of the river sections were polluted to different degrees, but the overall pollution was relatively light.
