【正文】 duced water quality and environmental capacity of sewage and sludge treatment conclusions to determine the criteria to be met, this section of its screening process flow for programs, and by demonstrating a reasonable choice of sewage and sludge treatment design uses A+A2/Oprocess. After treatment of urban sewage, 50% into the nearest body of water % of the municipal plex water, water quality should be the implementation of urban miscellaneous water quality standard (GB/T189202021). Key words: A+A2/O process water quality standards fully streaming process sewage and sludge treatment xx 工程學(xué)院畢業(yè)設(shè)計 3 目 錄 第一章 概論 ......................................................................................................................... 6 設(shè)計依據(jù) ...................................................................................................................... 7 設(shè)計水量及水質(zhì) ..................................................... 7 設(shè)計人口與當(dāng)量人口 ................................................. 7 處理程度 ........................................................... 8 第二章 工藝流程的確定 ................................................................................................ 9 ..................................... 10 我國城市污水今后發(fā)展的趨勢 ....................................... 10 確定污水處理方的原則 .............................................................................................11 第三章 污水處理構(gòu)筑物設(shè)計 ......................................... 16 進(jìn)水閘井 ....................................................... 16 污水泵房的設(shè)計 ................................................. 17 中格柵設(shè)計 ..................................................... 19 細(xì)格柵設(shè)計 ..................................................... 22 旋流沉砂池的計算 ............................................... 23 初沉池設(shè)計計算 ................................................. 25 UCT 生化反應(yīng)池 .................................................. 28 二沉池的設(shè)計 ................................................... 39 第四章 消毒系統(tǒng) ...................................................... 43 污水消毒的目的 ................................................. 43 設(shè)計參數(shù) ....................................................... 43 加氯間及氯庫設(shè)計要求 ......................................... 43 液氯消毒的計算 ................................................. 44 貯泥池設(shè)計計算 ................................................. 44 消化池設(shè)計計算 .............................................. 44 接觸池 ......................................................... 45 計量設(shè)備 ....................................................... 48 第五章 污泥處理系統(tǒng) ................................................. 49 污泥處理工藝的選擇 ............................................. 49 污泥量的計算 ................................................... 49 污泥濃縮池 ..................................................... 50 貯泥池的設(shè)計計算 ............................................... 53 機械脫水 ....................................................... 54 第六章 中水回用系統(tǒng) ................................................. 56 xx 工程學(xué)院畢業(yè)設(shè)計 4 處理流程 ....................................................... 56 中水泵房設(shè)計計算 ............................................... 56 絮凝沉淀池 ..................................................... 57 斜管沉淀池設(shè)計計算 ............................................. 60 普通快濾池 ..................................................... 63 消 毒 ........................................................... 70 清水池設(shè)計 ..................................................... 70 第七章 污水廠總體布置 .............................................. 72 平面布置 ....................................................... 72 污水廠高程布置 ................................................. 72 第八章 工程概預(yù)算及運行管理 ...................................... 76 污水處理成本分析 ............................................... 76 污水成本估算 ..............................
