【正文】 法、污水處理 Λァあ＊大學(xué)本科生畢業(yè)設(shè)計（論文） ii ABSTRACT This is a design about the sewage treatment plant of wuhan city. The flow of sanitary sewage that should be designed is: 150000 m3 / d, Inflow water quality: BOD5=250mg/l, COD=550mg/l, SS=260mg/l. The standard quality of water treated is: BOD5=20mg/l, COD=80mg/l, SS=20mg/l. Design content mainly includes two parts: the sewage disposal part, Sludge treatment. The centre technology of the design method is Adsorption Biodegradation. By paring the choice AB method for the optimum process is determined. After selected process flow, in accordance with the order of the process flow for structure design and calculation, in finishing the design and calculation of sewage and sludge treatment structures, based on the principle of plane layout, prehensive consider all aspects of factors in the sewage plant layout. According to the sewage flow tube drainage of connecting the structures of the diameter, velocity and hydraulic gradient, for sure, and then the hydraulic loss calculation. According to the hydraulic loss calculation of sewage and sludge elevation calculation and layout. Finally pleted the plan, elevation drawing and all kinds of the main structures of drawing. In the sludge treatment, residual sludge sedimentation tank by gravity artesian to gravity concentration pool. To reduce the moisture content of sludge, reduce sludge volume. Mud after enrichment, the moisture content is also big, the volume is still very big. For prehensive utilization and final disposal, drying and dehydration of sludge treatment. Keywords: AB, sewage disposal Λァあ＊大學(xué)本科生畢業(yè)設(shè)計（論文） iii 目 錄 摘 要 ..................................................................................................................................... i ABSTRACT .............................................................................................................................. ii 第一章 前 言 ................................................................................................................... 1 第二章 設(shè)計基本資料 ..................................................................................................... 2 、原始資料 .................................................................................................................... 2 設(shè)計內(nèi)容 ....................................................................................................................... 3 第三章 污水處理常見方法簡介及方案比選 ........................................................... 6 污水處理常見方法簡介 ............................................................................................ 6 深井曝氣活性污泥法 ........................................................................................ 6 AB 法 ............................................................................................................... 6 氧化溝法 .......................................................................................................... 7 SBR 法 ................................................................................................................ 8 方 案比選 .................................................................................................................... 8 SBR 法在工藝方面的主要特征 ..................................................................... 8 AB 法在工藝方面的主要特征 ....................................................................... 9 AB 法的生產(chǎn)原理 ............................................................................................... 9 構(gòu)筑物的選擇 ............................................................................................................ 9 格柵的選擇 ........................................................................................................ 9 沉砂池的選擇 .................................................................................................. 10 沉淀池的選擇 .................................................................................................. 10 、污水處理程度的確定 .............................................................................................. 12 污水的 SS 處理程度計算 ................................................................................ 12 污水的 BOD5處理程度計算 ........................................................................... 13 污水的 COD 處理程度的計算 ........................................................................ 13 第四章 主要處理構(gòu)筑物的設(shè)計計算 ....................................................................... 15 粗格柵的設(shè)計 ............................................................................................................ 15 設(shè)計參數(shù) .......................................................................................................... 15 格柵的間隙數(shù) .................................................................................................. 15 格柵槽 寬度 ...................................................................................................... 15 通過格柵的水頭損失 ...................................................................................... 16 Λァあ＊大學(xué)本科生畢業(yè)設(shè)計（論文） iv 柵后明渠的總高度 .......................................................................................... 16 格柵槽總長度 .................................................................................................. 17 每日柵渣量的計算及格柵除污機的選用 ...................................................... 17 細格柵的設(shè)計 ............................................................................................................ 18 設(shè)計參數(shù) .......................................................................................................... 18 格柵的間隙數(shù) .................................................................................................. 18 格柵槽寬度 ...................................................................................................... 18 通過格柵的水頭損失 ....
