【摘要】 以保定市城区水系管理委员会2017年3月16日公布的黑臭水体护城河河流中的6.235 km的黑臭水体段为参考进行了勘查、取样,与COD实验工作小组一起对保定市莲池区附近的护城河河流及水质COD变化进行了抽样研究。于2018年10月29日至11月25日将近1个月的时间,通过现场调研、布点采样并结合实验分析和环境评价,对保定护城河的水质状况和污染物特点进行了全面系统地分析,研究结果表明:护城河不同位景水中COD大小不同。为此,提出了切实可行、经济有效、便于管理的控制方案。更多还原

【Abstract】 Based on the 6.235 km black-smelly water section in the moat river of Baoding city published by the urban water system management committee on March 16, 2017, the exploration, sampling and COD experiment working group conducted a sampling study on COD changes in the moat river and water quality near Lianchi district of Baoding city. From October 29 to November 25, 2018, this paper made a comprehensive and systematic analysis of the water quality and pollutant characteristics of Baoding moat through field investigation, spot sampling, experimental analysis and environmental assessment, and proposed a feasible, economical and effective control approach scheme that is convenient for management. The results show that COD is different in different moats.更多还原
