摘要:
在南水北调东线工程黄河以南区域,对河流、湖泊的底泥进行了监测,并对不牢河的底泥进行了冲刷试验,根据获得的实测资料和试验数据,对底泥污染物对水质的影响进行分析评价.结果显示,底泥中的重金属类汞和砷,有机类污染指标中的总磷,总氮,CODCr和CODMn的最大溶出浓度均较高,它们有可能成为影响水体质量的潜在污染源.从接近于实际调水情况的冲刷试验结果看,底泥中的污染物对水体水质的影响较小.

Abstract:
In the southern part of the East Route Project of South to North Water Transfer,sediments in rivers and lakes were monitored and the washing experiment carried out in the reach of the Bulao River.Based on the data from the sediments monitoring and washing experiment,impacts of pollutants in sediments on the water quality was assessed.The results show that the maximum concentrations of dissolved Hg,As,TP,TN,COD\-\{Cr\} and COD\-\{Mn\} are higher and these may become potential polluting sources.It could be concluded that impact of pollutants in sediments on the water quality is relatively small from the washing experiment under the similar conditions of water transfer project.
