上海桃浦河水质现状分析与污染评价

桃浦河是上海苏州河的重要支流之一,其水质状况令人堪忧。选取桃浦河15个采样点,通过实地观测和室内实验分析,测得水体NH_4~+-N、COD_(Mn)、NO_2~--N、NO_3~--N等相关指标。运用国标对照、单因子评价法、模糊综合评价法等方法对桃浦河水体进行综合分析。结果表明桃浦河DO含量较低,NH_4~+-N含量超标严重,为劣5类水,水体自净能力总体较差,其中南段河流自净能力较好,其次为中段、北段。基于上述研究,提出了桃浦河整治的多项措施。

Current Situation of Water Quality and Pollution Assessment of Taopu River in Shanghai

The water quality of Taopu River,one of the important tributaries of Suzhou River,was worrisome.Selecting 15 sampling sites in Taopu River,the concentrations of NH_4~+-N,COD_(Mn),NO_2~--N and NO_3~--N were tested by observation on the spot and analysis in the laboratory.The water quality of Taopu River was assessed with GB 3838-2002,the single pollution index and Fuzzy Synthetic Evaluation.The results showed that the content of DO was comparatively low,NH_4~+-N over-standard seriously and the water quality was below the Class V water.Self-purification ability was overall weak with south section best,middle and north sections subsequently.Based on the above research, the rectification measures of Taopu River were put forward.
