Study On Landscape Design Of Urban Wetland Park Based On Reclaimed Water Reuse Method

Water resources are closely related to human life.Today,with the rapid development of economy,the utilization and protection of water resources has become a global problem that can not be underestimated.A large number of industrial and domestic sewage are discharged unreasonably,flowing into natural lakes and rivers,resulting in water pollution.The available water resources are decreasing day by day,the ecological imbalance and the vicious circle are increasing,which is very unfavorable to human sustainable development.Shuangyang District is the jurisdiction of Changchun City,located in the middle of Jilin Province,Southeast of Changchun City.In recent years,relying on its abundant resources,Shuangyang has become a pilot unit of the national rural governance system construction.In Shuangyang District,the tail water from shuangyingzi and Shiling sewage treatment plants is reused for power generation.Due to the protection of water environment,the outlet of surplus tail water is urgent to be solved.Reclaimed water reuse is a good way to solve the problem of sewage outlet,which can form the recycling of water resources,strengthen the protection and sustainable development of ecological resources,and constructed wetland is one of the most favorable ways for sewage treatment developed in recent years.The construction of Constructed Wetland Park can not only deeply treat sewage,but also produce huge economic and social benefits,It is an urban wetland ecological park that provides residents with leisure,entertainment,sightseeing,education and science popularization.This paper puts forward the research on landscape design of Urban Wetland Park Based on reclaimed water reuse,which has important practical significance.The main achievements of this paper are as follows(1)According to the research status and future development trend of sewage treatment,reclaimed water reuse,urban wetland park and sponge city at home and abroad,this paper summarizes the relevant theories,and explores the close relationship between the advanced treatment of tail water and Urban Wetland Park,so as to lay a theoretical foundation for the landscape design of Urban Wetland Park Based on reclaimed water reuse.(2)Through in-depth analysis of relevant successful cases at home and abroad,this paper summarizes the beneficial reference for this design,and finds the direction that needs attention and improvement,so as to ensure the practical significance of this design.The landscape design scheme of Urban Wetland Park Based on reclaimed water reuse is proposed.Through the design of sedimentation pond artificial aeration subsurface flow wetland surface flow wetland,with suitable wetland plants,through the calculation of water storage,the complete reuse of reclaimed water and further advanced treatment are ensured,and the rockery,ecological island,submerged corridor,education and science popularization area are constructed,To provide constructive guidance for the construction of constructed wetland urban wetland park landscape.(3)Taking Wolong Lake Wetland Park in Shuangyang District as an example,the landscape design theory and technology of Urban Wetland Park Based on reclaimed water reuse are applied to practice,so as to build an urban wetland park integrating advanced sewage treatment,reclaimed water reuse,sightseeing,leisure and entertainment,education and science popularization.
