Starch is the main characteristic of wastewater effluent contains a lot of anic matter, a high concentration anic wastewater, wastewater BOD so well. A starch factory of wastewater is 10000 m3 / d, CODCr of 8000 ~ 10000mg / L, BOD5 of 5000 ~ 7000mg / L, SS at 3000mg / L or so, pH value of 5, pH value of 5, the treated wastewater discharge standards Integrated Wastewater Discharge standard provides a secondary water quality standards. Starch produced from starch factory wastewater treatment process requirements for the use of UASB + SBR method.This design process is simple, small structures, better handling, and low cost, small footprint, suitable for medium and large starch factory wastewater.Keyword：Starch wastewater。 UASB。 SBR.III目 錄 .............................................................................................................................1 課題研究的意義，國內(nèi)外研究現(xiàn)狀和發(fā)展趨勢 ..............................................1 意義 ................................................................................................................1 國內(nèi)外研究現(xiàn)狀和發(fā)展趨勢 .......................................................................1 研究的主要內(nèi)容 ..................................................................................................1 課題的研究目標(biāo)、內(nèi)容和擬解決的關(guān)鍵問題 ..................................................2 .............................................................................................2 廢水處理工藝選擇原則 ......................................................................................2 廢水水質(zhì)分析 ......................................................................................................3 淀粉廢水進(jìn)出水水質(zhì)水量 ............................................................................3 淀粉廢水的特點(diǎn)及來源 ................................................................................3 設(shè)計涉及范圍及原則 ..........................................................................................3 工藝流程的比較 ..................................................................................................4 工藝方案的確定 ..................................................................................................6 處理工藝 UASB 反應(yīng)器 +SBR ...........................................................................7 方案特點(diǎn) ..............................................................................................................8 .................................................................................................................8 粗格柵 ..................................................................................................................8 集水井 ................................................................................................................10 提升泵房 ............................................................................................................11 細(xì)格柵 ................................................................................................................11 曝氣沉砂池 ........................................................................................................13 氣浮池 ................................................................................................................15 水解酸化池設(shè)計 ................................................................................................18 UASB 反應(yīng)器 .....................................................................................................21 SBR 反應(yīng)器 ........................................................................................................26 集泥井的 計算 ..................................................................................................29 污泥重力濃縮池 ..............................................................................................30 污泥脫水間 ......................................................................................................32 整個設(shè)計的超越管 ..........................................................................................32 ...................................................................................................................32 平面布置的一般原則和要求 ............................................................................32 具體平面布置 ....................................................................................................33 污水處理廠高程布置 ......................................................................................34 高程確定 ............................................................................................................35 ...................................................................................................................35 .......................................................................................36 勞動定額 ............................................................................................................36IV 運(yùn)行費(fèi)用的計算 ................................................................................................36 運(yùn)行費(fèi)用分析 ..............................................................................................36 運(yùn)行費(fèi)用計算 ......................................................
