Exploration Of Landscape Ecological Construction In Park-type Sewage Treatment Plant

Continuous progress of productivity and relations of production has aroused global change and urbanization of economy.The dramatic increase of urban population has exceeded the limit of environmental bearing and the urban environment becomes bad,and what threatens us most is the security of water ecological environment related to our life.To maintain the health of water ecological environment,the government has taken various measures for the management of pollution control;the construction of sewage treatment plant is one of them,which presents good effect for urban sewage treatment.Through investigation and collection on the development history of relevant information of sewage treatment plants both at home and abroad,focuses on the research on landscape construction of sewage treatment plant.In order to ensure the sustainable development of the urban environment,as well as the harmonious coexistence between people and environment,this paper puts forward the idea of ecological design incorporating into the landscape construction of sewage treatment station,with planning and design scheme based on the original site conditions.The selection of plants also take into account the particularity of sewage treatment plant and the regional landscape features,and in the design,the plant community of multi-layer composite structure composed of native plants such as small and medium-sized arbor,shrub and herb,to absorb-sound,reduce noise,deodorant,conserve water and soil,and it also has strong artistic appreciation effect.Meanwhile,this design study the construction of the water landscape and the aquatic plant,to improve the quality of the sewage water and the effect of landscape.This paper introduces two examples of landscape ecological sewage treatment plants that I participate in design and construction,Xiamen Houxi Industrial Sewage Treatment Plant and Sewage Treatment Plant of Wuyuanwan Wetland Park,constructs the park-type sewage treatment plant created by integration of landscape and ecology.The design express my personal understanding of the ecological concept in the sewage treatment plants,mainly focus on water purification,and it takes handled sewage as water sources of ecological water system,and then tests and compares data of water quality of the ecological water system before and after,by means of regular sampling,and it has shown that nitrogen,phosphorus and other nutrients has been effectively removed in the ecological water system.The ecological construction of sewage treatment plant may provide reference and development direction for the sewage treatment industry in our country's future.
