Reconstruction And Expansion Design Of The Urban Water Supply In Hulunbuir City

With the development of urban construction, water shortage and network lag problemincreasingly, seriously restricted the city construction and development. Countries pay moreattention on the water quality, water treatment technology is also becoming more and moreimportant.The hulunbuir city water plant enlarged (reform) in the city water supply shortage, andthe pipeline construction condition, the treatment, environmental protection is typicaly.Therefore, so, a study is made to this project. The thesis from the existing water supply capac-ity, water supply present situation and the existing problems and the pipeline network andshort-term&long-term water to predict that the city water supply,explain the necessity ofproject, then introduse the whole project specificly.The enlarge project mainly is to solve theinflux of old waterplant and pipeline construction lag.On the basis of water sources investigation, bayan sea town’s southern bridge4kmsouthwest of the south area, as the city planning water source, water usage groundwater aqui-fer as a city of water source water, the radiation well as water intake structures.Build a waterplant with the scale of50,000. The delivery pipe line used ductile iron pipe. The processchoosed： water pipe→plunge aeration→potassium permanganate→tube type mixeroxidation→fold board flocculating-reserved for carbon powder with air flotation→Ordinary rapid filter→Water chlorination. Water distribution network with the shallow bu-ried laid thermal insulation design, suitable to the long-term development of city construction.And the existing water transformation, the newly built pressure station project. Finally, theconstruction of the environment protection and the soil and water conservation are discussedin this paper.
