3201 某水廠給水工程設計,水廠,給水,工程設計 摘要：本設計的主要任務是內蒙古包頭市磴口水廠給水工程設計。設計的主要內容包括：設計規(guī)模的確定、給水系統(tǒng)選擇、給水方案比較、取水工程設計、 凈水廠設計和二級泵房設計。設計書由設計資料、設計說明 書和設計計算書三部分組成。本設計的設計規(guī)模是 6.5 萬 m3/d，以黃河干流為水源。采用的給水系統(tǒng)為：源水→斗槽（一泵房）→管式靜態(tài)混合器→機械絮凝池 + 往復式隔板絮凝池 →平流式沉淀池→V 型濾池→清水池→二泵→城市管網(wǎng)。 選用硫酸鋁為混凝劑，液 氯為 消毒劑。水廠出水水質要求達到生活飲用水衛(wèi)生規(guī)范（2001）。水廠位于包頭市郊，城市的東 南方，地面 標高為 1058m，總占地面積 4.70 公頃，綠化面積約占 25％，附屬面積約占總 面積的 15％，內 設標準化籃 球場和排球場，力爭創(chuàng)建一個清新怡人的現(xiàn)代化水廠。關鍵詞：斗槽，機械絮凝池，隔板絮凝池，平流沉淀池，V 型濾池， 泵房Abstract:The main task of my design is for the water supply engineering of dengkou water plant in the city of Baotou,Nengmenggu province. The design mainly includes: the calculation for the volume of the required daily water supply;the choice of the water supply system;the comparison for the process of water supply;the design of water source engineering;the design of the water plant and the secondary pumping station.The design file consists of three parts which are design data,explanation file and calculation file.The volume of the required daily water supply of my design is 65000 m3/d .Huanghe River is the source of the water supply. The system of the water supply which is adopted in my design is following:water source → bucket basin(first pumping station) →mixer →machinery flocculating tank+ baffleplate flocculating tank→advection sediment basin→v filter→clear-water reservoir→secondary pumping station→water network. Al2 (SO4) 2 is used as coagulant while Cl2 is used as disinfectant. The quality of processing water must satisfy the norm of domestic drinking water(2001).The water plant is located in the southeastern suburb of the city of Baotou whose elevation is 1058m.The plant covers 47000m2,which includes 25% green area and 15% accessory area.Besides,standardized basketball and volleyball grounds are set up in order to build a beautiful and harmonious water plant.Keywords:bucket basin, machinery flocculating tank, baffleplate flocculating tank, advection sediment basin, v filter, pumping station.
