【正文】 摘要 本設計為啤酒廢水處理工程設計，污水處理規(guī)模為 2500 m179。/d，廢水主要含有高濃度有機物，主要污染物質為 BOD COD、 SS；且 BOD5/CODcr值高，非常有利于生化處理，結合廢水的水質特征，及對各種處理工藝的對比，最終選擇 UASB+SBR作為處理工藝。 本工藝流程設有格柵、調節(jié)池，對污水進行預處理，去除水中較大的懸浮顆粒和調節(jié)水質水量。生化處理采用生物接觸氧化法， 可提高有機物去除效率。沉淀池用來進行泥水分離。 本文對格柵、調節(jié)池、 UASB 反應器、 SBR、污泥池等主要構筑物進行計算，編制設計說明 書，并繪制工藝流程、構筑物平面及高程、主要構筑物共四張圖紙。 關鍵詞： 啤酒廢水； UASB； SBR； Abstract The design for the design of brewery wastewater treatment, sewage treatment scale of 2500 m179。\/d, wastewater mainly containing high concentrations of organic matter, the main pollution material for BOD5, COD, SS。 and the BOD5\/CODcr value high, very conducive to biochemical treatment, bined with the characteristics of water quality of wastewater, and the parison of the various processing process, the final choice of UASB+SBR as the processing technology. This process is arranged in the grid, regulation pool, pretreatment of wastewater, the removal of larger particles suspended in the water and water quality regulation. Biological treatment by biological contact oxidation method, can improve the removal efficiency of organic pounds. Sedimentation tank for slurry separation. Regulation pool, in this paper, UASB reactor, SBR, sludge tank main structures are calculated, prepare the design specification, and rendering process, structures plane and elevation, the main structures of four drawings Keywords: Brewery wastewater。 UASB。 SBR。 目錄 一、 設計資料及要求 ...................................................................................................... 1 概述 .................................................................................................................... 1 設計資料 ............................................................................................................. 1 廠區(qū)地理位置 ............................................................................................. 1 廢水進水 .................................................................................................... 1 處理后水質要求 ................................................................................................ 2 二、 污水處理方案的確定 ............................................................................................... 2 設計思路 ............................................................................................................ 2 厭氧 好氧工藝選擇 ............................................................................................. 3 厭氧生物處理 .......................................................................................... 3 好氧生物處理 ............................................................................................. 3 方案比選 ............................................................................................................ 4 UASB+SBR 法處理啤酒廢水 ...................................................................... 4 UASB— 好氧接觸氧化工藝處理啤酒廢水 .................................................... 5 生物接觸氧化法處理啤酒廢水 .................................................................... 6 方案確定 ........................................................................................................... 7 三、 構筑物設計 ............................................................................................................. 9 格柵 .................................................................................................................... 9 設計說明 .................................................................................................... 9 設計參數(shù) .................................................................................................... 9 設計計算 .................................................................................................... 9 調節(jié)池 ............................................................................................................... 11 調節(jié)池作用 .............................................................................................. 11 設計參數(shù) .................................................................................................. 11 設計計算 .................................................................................................. 12 UASB 反應器 .................................................................................................. 12 UASB 反應器作用 .................................................................................... 12 設計參數(shù) .................................................................................................. 13 設計計算 .................................................................................................. 13 出水系統(tǒng)設計 ........................................................................................... 15 排泥系統(tǒng)設計 ........................................................................................... 15 SBR反應池 ....................................................................................................... 15 設計說明 .................................................................................................. 15 設計參數(shù) .................................................................................................. 17 反應池設計 .............................................................................................. 18 反應池控制 .............................................................................................. 19 排渠管道 .................................................................................................. 19 排泥系統(tǒng) .................................................................................................. 20 曝氣系統(tǒng) .................................................................................................. 20 空氣管計算 .............................................................................................. 22 潷水器
