【正文】 揚州大學環(huán)境科學與工程學院 畢 業(yè) 設 計 題目： 淮安市第三水廠及管網(wǎng)工程設計 專 業(yè) 給水排水工程 班 級 學 生 姓 名 完 成 日 期 2021 年 6 月 6 日 指 導 教 師 評閱 人 揚州大學本科生畢業(yè)設計 摘 要 本設計題目為： 淮安市第三水廠及管網(wǎng)工程設計 ,設計規(guī)模為：近期 100000 dm/3 ，遠期 202100 dm/3 ，要求根據(jù)所給資料進行 管網(wǎng)設計、 給水工藝設計和單體構筑物設計計算，包括取水輸水構筑物設計、輸配水管網(wǎng)設計、凈水廠設計、工程概算和 管網(wǎng)水力計算。凈水廠采用工藝流程為： 水源 → 一級泵房 → 混凝劑 消毒劑 ↓ ↓ 配水井 → 折板絮凝平流池 → 普通快濾池 → 清水池 → 吸水井 → 二級泵房 → 配水管網(wǎng) → 用戶 關鍵詞： 淮安市 ；給水工程；取水輸水構筑物；凈水廠；輸配水管網(wǎng) 。 Abstract The design entitled : Water Supply project enlarge preliminary design of Huaian City (Ⅲ ), the size of the design : the recent 100,000 dm/3 .Longterm 200,000 dm/3 , according to the given information, technology design and water monomer structure design and water intake structures are required. Transmission and distribution pipe work design, water purification plant design, engineering estimates and water costs are also included. Water purification plants’adopts technological is as follows: Water Resiyrce → Primary water pumping station → Coagulation Disinfection ↓ ↓ Assigned wells → Mechanical agitation clarifiers → Common fast filter → Storage pool → Water well → Secondary water pumping station → Urban pipe work → System users Keywords: : Huaian City。 Water supply engineering。 Water intake structures。 Waterworks。 Water Distribution 揚州大學本科生畢業(yè)設計 揚州大學本科生畢業(yè)設計 目 錄 1 概 況 ................................................................................................................................... 2 城市概況及自然條件 ........................................................................................................ 2 供水現(xiàn)狀及規(guī)劃 ............................................................................................................... 2 2 供水方案設計 ........................................................................................................................ 5 水源選擇 .......................................................................................................................... 5 取水點及取水構筑物型式確定 .......................................................................................... 8 廠址選擇 ........................................................................................................................ 12 水廠工藝流程確定 .......................................................................................................... 12 水處理構筑物型式選擇確定 ............................................................................................ 12 混凝劑種類及制備投加方式 ............................................................................................ 15 消毒劑及投加方式 的選擇 ............................................................................................... 18 3 各構筑物設計流量確定 ........................................................................................................ 20 最高日水量 .................................................................................................................... 20 供水變化曲線 ................................................................................................................. 20 消防水量 ........................................................................................................................ 20 4 取水構筑物及一級泵站設計 ................................................................................................. 22 取水頭部及引水管設計計算 ............................................................................................ 22 集水間設計計算 ............................................................................................................. 22 一級泵站水泵選型 .......................................................................................................... 22 一級泵站平面布置 .......................................................................................................... 23 一級泵站高程布置 .......................................................................................................... 24 一級泵站附屬設施 .......................................................................................................... 25 5 輸配水管網(wǎng)設計 ................................................................................................................... 27 輸水管布置 .................................................................................................................... 27 配水管布置 .................................................................................................................... 27 管網(wǎng)水力計算應注意的問題 ........................................................................................... 29 管材、附件及其埋設等 ................................................................................................... 30 水力計算 ........................................................................................................................ 30 消防時管網(wǎng)平差校核： ........................................................................................................ 34 6 凈水構筑物設計 ................................................................................................................... 35 進水分配渠 .................................................................................................................... 35 混凝劑、助凝劑制備投加及加藥間 ................................................................................. 35 ........................................................................................................... 36 ........................................................................................
