Study On The Design Of Drainage System In Jiangxi Province Town Center Town Center

For the construction of ecological civilization, and actively implement the town center of ecological sustainable development is the practical needs of ecological civilization construction, is to promote the transformation of the mode of economic development and environmental protection to combine a major strategic initiatives, is one of the effective ways for the sustainable development of urban and rural area, has become an important part of our national development. However, due to the economic development of the town center, the center of the town of sewage surge. Due to the lag of the economic development of center town, the lack of the necessary drainage and treatment facilities, a large number of domestic sewage and rainwater are without any emissions, serious pollution of the local environment, the construction of China's social caused very big impact. The lack of central town drainage system not only seriously restricts the sustainable development strategy of central town, but also seriously affects the life and health of the residents. Therefore, do a good job in the center of the town water pollution control work.The main research contents and results of this paper are as follows:(1)the basic data collection and analysis of the typical town of Jiangxi province. Conduct site investigation and consult the relevant data, in-depth analysis of its natural geography, hydrological environment, economic development, analysis of the history of the development of the sewage collection system. On the part of Jiangxi Province typical Central Town Center Township of on-the-spot investigation, on the town center present situation of sewage and water environment status were analyzed. It is found that the common problems in each center town and the analysis of these problems are analyzed and studied. It is found that most of the drainage system in the central town of Jiangxi province is the direct drainage system; the small part of the central town has no drainage system, and the rain water flows directly from the ground to the natural water body.(2)Study on the planning and reconstruction of the rain and sewage collection system and treatment system. Compared with the drainage system of the combined system, the diversion system and the mixed flow system, the adaptability of different drainage systems were analyzed. For the integrated oxidation ditch treatment system, constructed wetland treatment system, sewage treatment system of three kinds of sewage treatment system in the town of sewage treatment system were compared,and their respective applicable conditions were obtained. And puts forward the reference plan one one corresponding to the typical center proposed in the paper.(3)Stone town in front of pipe network system to reform design. Determine the stone town straight platoon type combined system transformation for intercepting drainage system, intercepting ratio through the comparison take 3, new and old city with incomplete separation of the connection. And to determine the local sewage quantity, integrated oxidation ditch sewage treatment plant construction 1500t/d. And on the local network of graphic design, the network graph drawing, sewage interception dry tube cross section diagram, rainwater jump well structural map, integrated oxidation ditch wastewater treatment plant layout diagram(see the figure).
