The recent processing capacity is 100,000 m3/d (in 2021) and the longterm processing capacity is300,000 m3/d (in 2020) .Raw water fill water: COD = 320mg/L, BOD5 = 160 mg/L, SS = 200 mg/L, NH3 N = 30 mg/L, TP = 4mg/L. Effluent quality should achieve standard B of Discharge standard of pollutants for municipal wastewater treatment plant. the total investment of sewage treatment plants is estimated about million yuan. The water treatment fee per ton water is yuan. with the adoption of technology Anaerobic pond ＆ Oxidation ditch The technological process is as follow: Sewage →coarse grille→ upgrade pumping station →fine grille → detritus chamber → Anaerobic pond →oxidation ditch→ secondary settling tank→ contact tank→ outward Keywords : sewage treatment plant 。Oxidation ditch。 Anaerobic pond。 the investment of sewage treatment plants 摘要 Ⅰ 目錄 Ⅲ 目錄 第一部分設(shè)計說明書 ............................................................................ 1 第 1 章 設(shè)計任務(wù)及資料 .................................................................... 1 設(shè)計任務(wù) ............................................................................................................ 1 設(shè)計依據(jù) ............................................................................................................ 1 設(shè)計資料 ............................................................................................................ 2 項目概況 .................................................................................................. 2 地形及地貌 .............................................................................................. 2 氣象 ......................................................................................................... 2 工程地質(zhì)及水文地質(zhì)： ............................................................................. 2 人口規(guī)模 .................................................................................................. 3 排水規(guī)劃 .................................................................................................. 3 設(shè)計原則 ............................................................................................................ 3 污水處理廠設(shè)計原則 ................................................................................ 3 污水處理工程運行過程中應(yīng)遵循的原則 .................................................... 4 第 2 章 工程總體設(shè)計 .......................................................................... 5 服務(wù)范圍 ........................................................................................................... 5 設(shè)計規(guī)模 ........................................................................................................... 5 進水水質(zhì)情況 ..................................................................................................... 5 出水水質(zhì)標準 ..................................................................................................... 5 第 3 章 設(shè)計方案論證 ........................................................................ 6 廠址選擇 ............................................................................................................ 6 污水廠處理流程的選擇 ....................................................................................... 6 確定處理流程的原則 ................................................................................ 6 污水處理 流程的選擇 ................................................................................ 7 污水處理流程方案的介紹與比較 ............................................................... 8 污水處理流程方案的確定 ....................................................................... 10 第 4 章 污水廠的工藝設(shè)計選擇 ......................................................... 11 格柵的選擇 .......................................................................................................11 沉砂池的選擇 ....................................................................................................11 氧化溝類型的選擇 ........................................................................................... 12 二沉池的選擇 .................................................................................................. 15 污泥處理工藝的選擇 ....................................................................................... 16 消毒池 ............................................................................................................ 18 巴氏計量槽 ...................................................................................................... 18 第 5 章 各建構(gòu)筑物設(shè)計規(guī)模 ............................................................ 19 污水提升泵房 ................................................................................................... 19 目錄 Ⅳ 細格柵 ............................................................................................................ 19 沉砂池 ............................................................................................................ 20 厭氧池 ............................................................................................................. 20 氧化溝 ..................................................................................
