Study On Landscape Construction Of Sewage Treatment Wetland

The early constructed wetlands in China are generally used as sewage treatment systems,and rarely reflected the landscape effect of wetlands.It was only in the last 20 years that landscape elements were gradually added to sewage treatment wetlands.However,landscape construction could not be well combined with the basic functions of water purification.For landscape design,it is different from the wetland environmental engineering project which only emphasizes the sewage treatment function,but also needs to pay close attention to its ecological function and landscape aesthetic value.Therefore,how to coordinate the conflicts among environmental engineering,landscape ecology and landscape architecture to build a wastewater treatment wetland landscape is the focus of the author’s research..The research mainly describes the research background,purpose,significance and content of sewage treatment wetland.Through the definition and classification of the related concepts of sewage treatment wetland,and then the wastewater treatment technology and wetland landscape construction respectively at home and abroad theoretical and practical progress research.This paper introduces the components,removal mechanism and technological process of constructed wetland wastewater treatment system,and analyzes its advantages and disadvantages.Based on the relatively isolated status of the wetland landscape,five parts of sewage treatment are put forward,which are the functional area of sewage treatment system determines the landscape functional area,the integration of water system and landscape design,the combination of planting design and pollution control function,the combination of pollution control education and popular science landscape,Integration of regional culture and wetland landscape.Based on this,it analyzes how the sewage treatment type wetland creates landscape features from five aspects: purification functional structures,water,revetments,plants and park essays.Finally,taking Hengxi Wetland Park in Hangzhou as an example,the present situation and existing problems are analyzed,the ecological landscape is constructed,the method of solving the practical problems is explored,and the constructed wetland environment which is coordinated with the sewage treatment is constructed.It can be used for reference to construct wetland landscape of sewage treatment in the future.
