宜兴百渎港桥断面污染源解析及水体达标研究

Research on Pollution Source Analysis and Section Attaining Standards of Baidu-Port Bridge in Yixing City

摘要: 百渎港桥断面为国控断面，2018年水质考核目标为Ⅲ类，2015年十二个月水质监测结果显示，百渎港桥断面氨氮和总磷尚不能达标。对百渎港桥断面水环境现状进行调查，分析污染物入河量及其构成，诊断和识别主要水环境问题，通过水文水质模型构建及模拟计算，提出保障断面达标的污染物削减方案。

Abstract: The section of Baidu-port bridge is state-controlled section, and the water quality assessment ob-jective for 2018 is class III. Water quality monitoring results of twelve months in 2015 showed that the water quality indexes of ammonia nitrogen and total phosphorus could not achieve standards. The present water environment situation of Baidu-port bridge section is investigated; the amount of pollution into river and its constitution are analyzed, and the main water environmental problems are diagnosed and identified. Through construction and simulation calculation of hydrology and water quality model, the pollutant reduction plan is put forward to ensure attaining standards of the section.
