摘要
内秦淮河(玄武段)逸仙桥断面属于水质考核市控断面,当前水质为劣Ⅴ类,2020年目标为Ⅴ类。本文通过周边水系调查、污染源强解析的途径,分析出逸仙桥断面水质超标主要原因为雨污分流尚未全部完成,玄武湖补水不足、内源和降雨径流污染,并进行污染源削减和生态补水水质达标方案分析,提出了针对性较强的对策,为地方环保管理部门提供技术支撑,这对改善秦淮河流域水环境具有十分重要的意义。
The section of Yixian Bridge in the Inner Qinhuai River(Xuanwu Section) belongs to the municipal control section of water quality assessment. The current water quality is inferior to Category V, and the target for 2020 is Class V. In this paper, through the investigation of surrounding water system and the analysis of strong pollution sources, the main reason for the water quality of the section of Yixian Bridge is that the rainwater and sewage diversion has not been completed, and the Xuanwu Lake has insufficient water supply, endogenous and rainfall runoff pollution. The pollution source reduction and ecological hydration water quality compliance plan analysis were carried out, and the targeted countermeasures were put forward to provide technical support for the local environmental protection management department, which is of great significance for improving the water environment of the Qinhuai River Basin.
