Study on Ecological Landscape Design in Rural Sewage TreatmentTaking Sanmenxia Lushi Sewage Treatment Station as an Example

China Abstract: The problem of water pollution is one of the long-term difficulties in the process of rural environmental construction and economic development in China. In order to meet the requirements of the country’s green and sustainable development, many regions actively promote the construction of rural sewage treatment and fill in the shortcomings of the rural habitat environment to accelerate the construction of beautiful and livable villages.Through a lot of literature and case studies, this paper explores the environmental problems that are common in rural sewage treatment in the northern region of China, explores advanced domestic and foreign cases and technologies on this topic, and summarizes the landscape design strategies on this issue. From the perspective of ecological landscape design, the thesis seeks the theoretical and technical support for rural sewage treatment in river valley areas, and establishes a bridge between rural sewage treatment technology and ecological landscape. Finally, combining theory with practice, taking the project of Lushi sewage treatment in Sanmenxia as an example, team completed the landscape design of ecological sewage purification display area in Zhangjiacun.The design focuses on presenting the application of internal sewage treatment technology and external landscape aesthetics. According to the main points of ecological landscape design and the theory of ecological edge effect, the local ecological system is effectively protected, and a rural domestic sewage purification display area with economic benefits is
