保定市一亩泉河河流中COD的变化及污染源分析

Analysis of COD Changes and Pollution Sources in Yimuquan River in Baoding

针对保定市城区水系管理委员会2017年3月公布的黑臭水体河流中的一亩泉河7.23km的黑臭水体段为参考进行了勘查、取样与COD实验工作,从2019年4月12日到2019年5月29日进行了为期一个半月的时间。研究结果表明:保定市一亩泉河河流不同位置COD大小不同、污染原因不同。通过周围景观的变化、对采样点附近居民进行的走访和COD浓度的测定,对一亩泉河的水质状况和污染源进行了全面系统地分析。并为此提出了切实可行、经济有效、便于管理的控制方案。

The exploration,sampling and COD experiment were carried out from April 12,2019 to May 29,2019 for a period of one and a half months,with the 7.23 km section of theblack and smelly water body of Yimuquan river in the black and smelly water body published by Baoding urban water system management committee in March2017 as the reference.The results show that COD size and pollution cause are different in different places of the Yimuquanhe river in Baoding.Through the change of the surrounding landscape,the visit of the residents near the sampling point and the determination of COD concentration,the water quality and pollution sources of the Yimu spring river were analyzed comprehensively and systematically.A feasible,economical and effective control scheme is put forward.
