城市河道黑臭水体污染治理技术初探

Study on Pollution Treatment Technology on Black and Odorous Water in Urban River

近年来,城市黑臭水体问题益发严峻,严重影响了公众对城市环境的感官认知,威胁了水质安全。本文归纳了黑臭水体形成的原因,分析了有机污染物、重金属、温度、溶氧量、径流量等对黑臭水形成的影响,总结了城市水体的常见污染源,从物理、化学、生物-生态三方面概括了国内现有的治理黑臭河流的技术方法以及研究动态,以期为我国城市黑臭水体科学系统的治理提供借鉴。

Black and odorous water problems in urban city have become increasingly serious in recent years,which impact the public badly on the sensory perception of urban environment and threatened water safety. In order to provide valuable reference on controlling blackening and stink of rivers,the reasons of black smelly water,the influence of organic pollutants,heavy metal ions,temperature,dissolved oxygen content and runoff on black smelly water,the common sources of water pollution in urban waters,the recent research and development on controlling blackening and stink of rivers from several aspects such as physical,chemical and biotechnology-ecological engineering were summarized.
