摘要:
以京杭运河镇江段为研究对象,根据2017—2019年6—7月、2020年6月1日—8月3日、2020年6月17日—19日3个时间段的镇江段5个控制断面监测数据、江苏省水环境监控系统平台监控数据和现场专项调查监测数据,分析了梅雨季节降雨期间高锰酸盐指数和总磷浓度时空变化规律,总结出了可能影响水质波动的原因。结果表明:不利气象条件、起始处受污染、雨污分流建设滞后、支流水质较差和农业面源污染是造成京杭运河镇江市段水体污染的原因。提出,应加强全市排涝泵站的管理、加强入河排污口监管、加快建成区雨污分流建设、减少农业面源污染等建议。

Study on Water Pollution in Zhenjiang Section of Beijing-Hangzhou Grand Canal during Rainy Season
YIN Wei-qing
Abstract:
Taking Zhenjiang section of the Beijing Hangzhou Canal as the research object, this paper analyzed the spatio-tempral variation characteristic of permanganate index and total phosphrous in rainy season, and the reasons why water quality fluctuated were summarized. The monitoring data were obtained during the following three periods from June to July in 2017—2019, June 1st to August 3rd and June 17th 19th in 2020, and from 5 controlled sections, Jiangsu Province water environment monitoring platform and on-site surveys. The results show that unfavorable weather conditions, pollution at the beginning, delayed on rain and sewage diversion construction, poor water quality in tributaries, and agricultural non-point source pollution are the reasons for the impact of surface water pollution in Zhenjiang City. It is proposed that the management of the citys drainage pumping stations should be strengthened, the supervision of sewage outlets into the river should be strengthened, the construction of rain and sewage diversion in built-up areas should be accelerated, and agricultural non-point source pollution should be reduced.
