上海城区中小河道黑臭水体修复关键技术初探

Primary Study on the Key Technologies for Remediation of Small Malodorous Black River in Urban Area of Shanghai

目前在上海城区中小河道黑臭水体修复过程中,应用生物修复特别是生态工程的方法是修复技术的主体。根据对其黑臭的背景分析,发现水体有机污染较严重,河道富营养化趋势较为明显。有鉴于此,在中小河道经先期治理的基础上探讨了高效生物膜、生态浮床和水生植被重建三项关键技术。指出上海中小河道黑臭的现状决定了采用这些关键技术是比较合适的。

Bio-remediation especially the technology of ecological engineering is now the subject in the process ofthe small rivers＇ remediation in Shanghai. Based on the analysis of the malodorous black water bodies＇ background, theserious organic pollution of rivers and obvious tendency to eutrophication were demonstrated. According to the analysisand the foundation of pre-treatment, the author discussed the application of three main key technologies.-ecologicalfloating-floor, efficient biofilm carrier and macrophyte reestablishment, At last, it＇s suitable to indicate that these keytechnologies are appropriate for treating the malodorous black rivers in the urban area of Shanghai.
