湘江株洲段丰水期镉污染负荷总量测算及分配
Cadmium pollution load calculation and allocation of Xiangjiang River located in Zhuzhou district during wet period
摘要
Abstract
Based on the water quality and sediment monitoring data of the representative cross-section of Xiangjiang River in Zhuzhou district in August 2010 and other material,the Cd concentration of the section was simulated by using WASP 7 model and Cd pollution load was calculated and allocated.The results showed that Cd concentration variation was reproduced by WASP 7 model.In August the upstream river cadmium inflow was 2 446.33 kg,and a flow downstream was 3 076.44 kg,with a range increment of 630.12 kg,of which point source load 241.67 kg,accounting for 38.4%,non-point source load 304.49 kg,accounting for 48.3%,endogenous load of 83.96 kg,accounting for 13.3%.关键词
