The Waterscape Design Of Small Scale Wetlands For Wasterwater Treatment

Constructed wetland is a kind of artificial wetland system construction, with sewage purification, improve the ecological environment, enhance the landscape quality and other functions, it is worth promoting to make up for the sewage purification function of natural wetlands which is gradually diminishing. In the landscape architecture, water elements,as the body of wastewater treatment wetlands, is different from the projects which only emphasizes the effect of sewage purification,which both has ecological functions and aesthetic value.This paper is divided into six chapter.The first chapter is a brief summary of the main research background, significance, research progress at home and abroad, and proposes on the basis of this proposed this article research frame.The second chapter is reviewed articles, including two aspects of related theories to constructed Wetlands and waterscape design. The theory of constructed Wetlands is the summary of four aspects:concept, elements, types, purification mechanism and process aspects elaborate. The theory of waterscape design summary three aspects:Chinese traditional water art, western waterscape art, modern waterscape art.The third chapter is the case analysis, summarize the three aspects from the project to create a profile, process, waterscape,investigating by large number of small-scale wastewater treatment wetlands case in Beijing, Shanghai, Hangzhou, Chengdu.The fourth chapter is strategy papers,discusses the four factor influence of waterscape by case, namely, water parameters, terrain, structures, processes, and water symbiotic elements (revetment, plants, road),and summarizes Three strategies for purification constructed wetlands, building security pattern of water bodies, water landscape pattern, human hydrophilic behavior pattern.The fifth chapterr is desing chaper, an example of Xian Hai Lake XiTang Water Street including two aspects:water parameters and watersape design. Water parameters are introduced for the background of constructed wetland sewage treatment technology,but the focus is to study is watersape design. By Xian Hai Lake XiTang Water Street pond theoretical study,to further explore the issue and solutions constructed wetlands waterscape faced in practice.The sixth chapter summarizes the papers, proposed the problems of small-scale wastewater treatment wetlands and its development prospect.
