北京某小型黑臭水体治理实践与技术探索

针对北京某小型河道黑臭现状,采用控源截污、内源治理、活水循环、造流增氧、生态修复等组合措施治理。治理2月余,实现了臭味完全消除,水体透明度由8 cm提高至50 cm;治理1年余,除TN外的指标均达到地表Ⅴ类水标准;治理2年余,各水质指标达到地表Ⅳ类水标准。实践证明,该组合技术可安全、高效地消除水体黑臭。

Practice and Technical Exploration on the Treatment of a Small Black and Odorous Water Body in Beijing

In view of the black and odorous condition of a small river in Beijing,the combined measures of source pollution interception,endogenous treatment,living water circulation,aeration and ecological restoration were adopted.After two months of operation,the odor was completely eliminated,and the water transparency was increased from 8 cm to 50 cm.After 1 year of treatment,all indexes except TN reached levelⅤcriteria of Environmental Quality Standards for Surface Water(GB 3838-2002).After over 2 years of treatment,all water quality indexes had reached the levelⅣcriteria of the standard.Practice had proved that the combined technology could eliminate black and odorous water body safely and efficiently.
