摘　　要：河道水体污染对环境和人类健康造成了极大危害,为此进行低强度曝气技术在河道水体污染综合治理中的应用研究。以北京市潮白河顺义段为例,针对该区域的水体污染采用低强度曝气技术进行综合治理,阐明技术原理和基本操作流程,采集低强度曝气技术应用前后的河道水样,检测化学需氧量、色度、气味阈值、过氧化物酶四个指标。结果表明:随着低强度曝气技术应用时间的延长,化学需氧量、色度、气味阈值三个指标均在逐渐降低,而过氧化物酶在逐渐升高,说明较治理前河道水质明显改善。River water pollution poses great harm to the environment and human health.Therefore,this study analyzed the application of low-intensity aeration technology in the comprehensive treatment of river water pollution.Taking the Shunyi section of the Chaobai River in Beijing as an example,low intensity aeration technology is adopted for comprehensive treatment of water pollution in this area.The technical principles and basic operating procedures are explained,and river water samples before and after the application of low intensity aeration technology are collected to detect four indicators:chemical oxygen demand,chromaticity,odor threshold,and peroxidase.The results show that as the application time of low intensity aeration technology prolongs,the three indicators of chemical oxygen demand,chromaticity,and odor threshold are gradually decreasing,while peroxidase is gradually increasing,indicating a significant improvement in river water quality compared to before treatment.
