【摘要】：杭州是一座因水而兴的城市,城市河道密集,在杭州漫长的历史中,众多的城区河道发挥运输、灌溉、排水、泄洪和美化市民生活的作用。随着城市的发展,河道水环境污染越来越严重,黑臭河频现。自80年代开始对河道水环境进行治理,水质改善取得了明显成效,分析其原因,都与河道整治、截污纳管、河道配水和河道清淤等综合治理,减少排入河道的污染物总量有着密切的关系。通过对目前杭州城市典型河道现状的调查研究,主要针对河道的名称、地点、河道规模、功能定位、现状护岸情况、现状水质调查、两岸土地利用、滨河排水设施、河道闸坝设置、水质等情况进行了认真调研,了解了河道水环境现状,综合分析河道治理相关实例,发现杭州河道治理相关措施主要包括截污、配水、清淤以及生态治理等。同时对上述四大类河道水环境治理技术进行研究,详细分析了这个四类治理技术的实施要点、优势局限、适用范围以及经济环境效益。提出了河道水环境治理中,必须加强监管,因地制宜地合理选择组合技术和治理措施,以达到技术经济可行、治理效果和环境效益显著的目的。最后,本文认为要保持河道水环境的治理效果,必须坚持科学规划、标本兼治,末端治理和源头治理相结合,强化长效管理。
[Abstract]:Hangzhou is a popular because of water city, dense rivers in Hangzhou City, long history, many of the urban river transport play, irrigation, drainage, flood discharge and beautify the public life. With the development of the city, river water environment pollution is becoming more and more serious, the black smelly river since 80s and Governance are frequent. On the river water environment, water quality improvement and achieved remarkable results, analysis of its causes, and river regulation, intercepting sewer, river water and river dredging comprehensive management, reduce the amount of pollutants discharged into the river have a close relationship. Through the investigation on Hangzhou City typical river situation at present, mainly for river the name, location, channel size, function, status of revetment, water quality status quo survey, on both sides of land use, river drainage facilities, river gate dam set, the water quality situation seriously investigation, understand the river water The environmental status quo and relevant examples of comprehensive analysis of the river, Hangzhou River found relevant measures mainly include sewage interception, water distribution, dredging and ecological governance. At the same time to study the above four kinds of river water environmental control technology, a detailed analysis of the main points, implementation of the four types of treatment technology advantages, limitations, scope and economic environment the benefit is proposed. The river water environment governance, must strengthen the supervision, to choose reasonable combination of technology and management measures, in order to achieve the feasibility, treatment effect and environmental benefit is obvious purpose. Finally, this article believed that to preserve the river water environment governance effect, we must adhere to the scientific planning, tackling the problem, the end of treatment and the combination of the source of governance, strengthen the long-term management.
