太湖典型入湖河流底泥中磷的污染特征研究

摘 要：对太湖流域江苏宜兴市的六条典型入湖河流底泥磷的污染的调查研究，磷的分析结果表明，不同河流中底泥磷的污染相差较大。洪巷、官渎、大港TP的变化范围是143mg/kg ~502mg/kg，Fe/Al-P百分比远小于Ca-P。太滆、沙塘、殷村TP变化为263mg/kg~1373mg/kg, Fe/Al-P的百分比较接近于Ca-P。洪巷、官渎和大港三条河流污染段集中在中游，而在太滆、沙塘、殷村的大部分河段污染严重。从垂直方向实验数据表明这几条河在近年来的治理中已有一定成效，但仍需努力。

Study on the pollution characteristic of phosphorus in sediment of typical Inflow Rivers of Taihu Lake
Abstract ：The study about six inflowing rivers of the Tai Lake region basin phosphorus of sediment indicated that there is big difference among the different rivers. In the Hongxiang, Dagang, and Guangdu rivers, TP Change from 143 mg/kg~502 mg/kg, and the percentage of Fe/Al-P is far less than Ca-P. In the Taige, Shatang, and Yincun rivers, TP Change from 263mg/kg~1373mg/kg, and the percentage of Fe/Al-P approximates to Ca-P. In the Hongxiang Guangdu and Dagang, their heavy polluted sections are mainly collect middle reaches. In the Taige, Shatang, and Yincun rivers, there are a lot of sections have been polluted .Through the vertical experimental data, these rivers acquire some effect at pollution treatment, and we must do more effort to improve the water quality.
