摘要
根据估算,宜兴生态引领区COD、NH3-N、TN、TP入河总量分别为6728.70、714.95、3562.24、308.50 t/a。宜兴生态引领区不同的水生态环境功能区主要污染物入河量排序为Ⅲ-07>II-03和Ⅲ-11>Ⅰ-03>Ⅲ-10>Ⅱ-02。根据不同产业估算,污染物入河量中COD、NH3-N主要来源于生活污染源,分别占59%、57%,TN、TP主要来源于第一产业,分别占73%、90%,这就为确定宜兴生态引领区水污染治理重点区域、重点产业提供了科学依据。
According to the estimation,the total amount of COD,NH3-N,TN and TP entering the river in Yixing eco-leading area are 6728.70,714.95,3562.24,308.50 t/a.The order of quantity of pollutants into river in the different water eco-environmental function areas of the Yixing Ecological leading area isⅢ-07>Ⅱ-03 andⅢ-11>Ⅰ-03>Ⅲ-10>Ⅱ-02.According to estimates of different industries,COD and NH3-N in the quantity of pollutants into the river mainly come from living sources,59%and 57%respectively,and TN and TP mainly come from primary production,73%and 90%respectively,which provides a scientific basis for the determination of key areas and key industries of water pollution control in Yixing eco-leading area.
