AnkangHengkou District Drainage Project, Special Planning And Design

AnkangHengKoudistrict (that is demonstration area), is located in the middle of Yue river. the river with road three fulcrum and "two wings" is one of the core industry gathering area,andbe approved by provincial party committee and government, the balance urban and rural integration development of the comprehensive reform experimental area, also is the national development and reform testing. Currently,Heng Kou area with few confluence sewage pipe canal collection system, there is no sewage treatment plants, sewage and rainwater via the drain line and the Heng river, cause serious pollution to local environment, the Heng river into the han river, also caused serious pollution to the han river water environment.In view of the above problems in the AnkangHengKoudi strict, To 2014 as the year of planning,2020 for the planning and construction of the year.Water drainage project planning within the scope of 16 square kilometers inHengKoudistrict,built in to cover over 95% of the sewage pipe network, sewage collection rate of 90%, Water treatment standard to reach the 《town sewage treatment plant pollutant discharge standard》 (GB18918-2002) standard level 1 A.Planning and design adopts rain sewage diversion system. Rainwater collected through storm sewer drainage according to the terrain and road elevation nearby discharged into the Heng river and Yue river; The 2 years in accordance with the design, the design flow for0.12m3/s The total length of the rainwater pipe network is 70.188km, the length of which is 18.534km,Diameter is DN400, DN500, DN600, DN700, DN800.Sewage through the sewage main pipe into the planning and construction of a unified sewage treatment plant sewage treatment plant to deal with, and ultimately into the Han River.The design flow rate is 0.45m3/s, the total length of the pipeline is 70376km, and the length of the main pipe is 25.216km,Diameter is DN500, DN600, DN700.Investment analysis of the drainage pipe network project in thehengkou area, The project total investment 182.9444 million yuan, of which the sewage pipe network construction investment of 73.6511 million yuan, rainwater pipe network construction investment of 109.2933 million yuan.The implementation of the project, will greatly improve the quality of local surface water environment, greatly enhance the life of the local environmental standards to improve the urban residents living environment quality, and Promoting the coordinated development of various construction in t AnkangHengKoudistrict.
