Research On The Planning Of Urban Drainage

In recent years, with the development of social economy, urbanization process isaccelerating, the severe shortage of water resources, serious pollution of the waterenvironment, the township sewage collection rate is low, seriously restrict the development ofthe social economy of Caijiapo town. In order to change this situation, to develop acomprehensive, professional drainage planning has been imminent.The thesis takes Shaanxi province Shanxi County Caijiapo town drainage plan as anexample, the new scientific idea, to summarize some general points of drainage problems,work and encountered the urban drainage planning process, to study and explore.Prediction and planning period sewage quantity the proportion correlation method, areasonable division of the township sewage drainage area, determine the sewage flow ratio,put forward reasonable scheme of the sewage pipe layout and material selection. Hydrauliccalculation of large amount of sewage pipe. Combined with the actual situation of theplanning area, determine the sewage treatment plant by using the improved Carrouseloxidation ditch process and puts forward the scale expansion. Feasibility study of Caijiapotown of reclaimed water reuse, through the comparison the reclaimed water reuse scheme iseconomical and reasonable. Through the study of sludge treatment methods at home andabroad, combined with the actual situation of the planning area, staging determine sludgedisposal scheme.In the aspect of rainwater pipe network system planning, this paper analyzes thefeasibility of township waterlogged area reformation, and follow the "since the row, row asstrong, high water discharge, low water discharge, water, dispersing discharged nearby"principle, division of rainwater system partition and layout of the rainwater pipe network.Analysis of the rainwater resources comprehensive utilization of Caijiapo town and thefeasibility of rainwater system planning management.Finally, the thesis of the Caijiapo town sewage and rainwater pipe network phasedconstruction puts forward corresponding, project investment estimate, were reviewed andanalyzed and the urban drainage planning results.
