多方位生态修复技术在河道水环境治理工程中的应用
|
摘要
随着城市化进程的加快,河道水环境受到了不同程度的破坏,严重制约了城市水生态的可持续发展。基于近年来河道水体修复技术的工程实践经验,提出了"外源截留、内源控制、人工净化和自净强化"的多方位生态修复技术体系,并将其应用于深圳铁排渠示范河道水环境综合治理中。结果表明,该河道水质明显好转,由劣V类水质变为IV类水质,水体的COD、NH_3-N、TP等水质指标均大幅度降低,取得了理想的水体景观及水质效果。
With the rapid development of urbanization,the river water environment is suffering different degrees of damage,which seriously restricts the sustainable development of urban water ecology.Based on the engineering experience of the river water restoration technology in recent years,multi-dimensional ecological restoration technology system,including‘exogenous interception,endogenous control,artificial purification,self-purification strengthen'is put forward.It has been applied in the river water environmental treatment of Tiepai River in Shenzhen City.The results show that the water quality has been improved obviously from bad class V to class IV.The water quality indexes,such as COD,NH3-N and TP,have been significantly decreased and it has achieved the ideal effect of landscape and water quality.
