摘要
本文介绍了杭州清晖河西湖区河道生态治理和景观提升工程,主要生态修复技术以沉水植物恢复为主,同时辅以外源污染接触处理、曝气复氧、生物操纵、水下种植槽等综合治理措施。经11个月的跟踪监测,水质得到了明显改善,COD Mn、TP、NH 3-N指标均有所下降。经过治理后,最终构建了健康、稳定的水生生态系统。此生态修复工程的成功实施可为类似城市河道的生态修复提供有益参考。
This paper introduces the river ecological treatment and landscape improvement project carried out after the polluted waters of the West Lake District of Qinghui River in Hangzhou.The project mainly focuses on the restoration of submerged plants,supplemented by comprehensive ecological restoration technical measures such as contact treatment of exogenous pollution,aeration reoxygenation,biological manipulation,underwater planting tank,etc.After 11 months of follow-up monitoring,the water quality has been significantly improved,and the indexes of COD Mn,TP and NH 3-N have all decreased.After treatment,a healthy and stable aquatic ecosystem was finally constructed.The successful implementation of this ecological restoration project can provide useful reference for ecological restoration of similar urban rivers.
