高密度城中村黑臭河涌治理措施研究

Study on Control Measures of Black and Smelly River Swell in High-density Urban Villages

高密度城中村给城市带来诸多便利和活力,但也带来了交通拥堵、资源短缺、环境污染等一系列问题,且普遍具有排水基础设施不完善、水体岸线土地空间受限、区域城市管理力度薄弱等特点。为研究高密度城中村黑臭河涌的治理措施,本文以广州市白云区某河涌作为案例河涌,详细分析了导致其黑臭的原因及问题,进而针对性地提出4项工程措施和4项管理措施。通过各项措施的有力实施,使案例河涌的水质从重度黑臭(氨氮>15mg/L)变为地表水V类(氨氮<2mg/L)水质标准,达到了良好的效果,为今后类似的黑臭河涌治理工程提供参考。

High-density urban villages bring a lot of convenience and vitality to the city,but also bring a series of problems such as traffic congestion,resource shortage and environmental pollution.It is generally characterized by imperfect drainage infrastructure,limited land space along the water body and weak regional urban management.In order to study the control measures of black and smelly river swell in high-density urban villages,this paper takes a river swell in Baiyun District,Guangzhou as a case study,analyzes the causes and problems leading to the black and smelly river swell in detail,and then puts forward 4 engineering measures and 4 management measures.The water quality of the river surge in the case changed from severe black odor(ammonia nitrogen>15mg/L)to surface water class V(ammonia nitrogen<2mg/L)water quality standard,which achieved good results,and provided reference for similar black odor river surge control projects in the future.
