摘要
某公园人工湖水质富营养化严重,采用异位净化、原位修复和水力循环为主的技术体系进行水质改善,工程运行至今,除总氮外,其余人工湖湖水水质指标均满足《地表水环境质量标准》(GB 3838—2002)中Ⅴ类水体要求。实践证明,采用异位净化、原位修复和水力循环为主的技术体系对富营养化景观水体进行水质改善是可行的。
Eutrophication of artificial lake in a park was severe. A project was constructed for the improvement of water quality,in which the technology system of ex-situ purification,in-situ remediation and hydraulic circulation was used as the main treatment process. Since the project was put into operation,except for the total nitrogen level of water,the other indexes have met the class Ⅴ criteria specified in the Environmental Quality Standards for Surface Water（GB 3838- 2002）. The results indicated that the technology system of ex-situ purification,in-situ remediation and hydraulic circulation is suitable for water quality improvement of eutrophic landscape water.
