摘要
通过对重庆主城区江段2006～2010年主要代表监测断面水质监测数据的统计分析,对悬浮泥沙含量及其对污染物的影响进行研究。结果表明:监测断面的泥沙含量变化呈现出明显的季节变化特征,污染物浑样浓度明显大于清样浓度,并且浑样浓度变化与泥沙含量变化特征类似,这说明泥沙对这些污染物具有较为显著的吸附作用。
Statistical analysis have been conducted based on water quality data collected, from 2006 to 2010, in Chongqing Urban Section of Yangtze River and Jialing River, and the impacts on contaminants influenced by sand has been assessed. The analysis results show that sand level appear significant seasonal variation, while contaminants level in the turbid water sample, in general, are much greater than those in non turbid water samples. Moreover, the contaminants level tend to coincide with the shift tendency of sand level in turbid water. Therefore, which suggest sand might have substantial adsorption to those contaminants.
