摘要
广州市在城市黑臭水体治理方面取得积极进展,积累了一些先进经验和典型案例。以广州市双岗涌黑臭水体整治为案例,从水环境问题识别、整治思路与措施、治理成效3个方面进行总结与分析。针对双岗涌流域污水未有效截排、小微水体污染严重、河道被侵占、管理缺失等问题,提出控源、截污、清淤、补水、管理的技术路线,实施黑臭水体治理;其中,采用食藻虫引导水下生态修复技术对双岗涌周边3个鱼塘进行修复,构建了食藻虫+沉水植物+微生物共生系统,达到水质净化和恢复水体自然生态系统双重目的。双岗涌整治后,不仅消除了水体黑臭,还恢复了岭南水乡的河涌风貌。
Guangzhou City has made positive progress in the treatment of urban black and odorous water bodies and obtained some advanced experiences and typical cases.Taking the Shuanggangchong River in Guangzhou City as an example of the remediation of black and odorous water bodies,three aspects of water environmental problems identification,remediation ideas and measures,as well as the remediation effectiveness were summarized and analyzed.To address the problems such as ineffective interception of sewage in Shuanggangchong River Watershed,serious pollution of small and micro water bodies,the encroachment of river channels,and the lack of management,a technical route of source control,pollution interception,dredging,water replenishment,and management was proposed for the implementation of black and odorous water body treatment.Among them,a technology of Daphnia magna inducing aquatic ecosystems construction was used for the restoration of 3 fish ponds around the Shuanggangchong River,constructing an Daphnia magna+submerged plants+microorganisms symbiotic system for water quality purification and restoration of a natural aquatic ecosystem.After the remediation of the Shuanggangchong River,the black and odorous water body was eliminated and the river features of Lingnan-water-town were also restored.
