【正文】 某鋼鐵廠含油廢水處理工藝 摘 要 本次畢業(yè)設(shè)計的題目為 某鋼鐵廠硅鋼 4分廠含油廢水處理水站的設(shè)計 —— UASB+SBR 處理工藝 。根據(jù)污水進(jìn)水的水質(zhì)水量設(shè) 計 主要的污水處理構(gòu)筑物和水站的總平面布置，要求污水經(jīng)處理后可以達(dá)標(biāo)排放。 其中 廢水處理站 初步設(shè)計要完成設(shè)計說明書一份、 水站設(shè)計平面圖一張 ，流程圖 一張 ，高程圖 一張 ，主體構(gòu)筑物 剖面圖不少于 3 張 ， 設(shè)計圖紙總數(shù) 不少于 6 張。 本次設(shè)計以 鋼鐵產(chǎn)業(yè)含油廢水 主題， 處理污染物比較單一的工業(yè)生產(chǎn)污水 。其主要采用技術(shù)比較成熟的 UASB+SBR 工藝。 傳統(tǒng)的 SBR 適合于間歇排放 的工業(yè)廢水處理，且占地面積小耐有機(jī)負(fù)荷。但由于污水油濃度太大，易產(chǎn)生浮渣。而 UASB 法則可大大降低廢水中油含量和 COD 含量。所以將二者結(jié)合處理會有很好的效果。 關(guān)鍵詞： 含油廢水處理 ； UASB。 SBR Oily wastewater treatment process of a steel plant Abstract The topic of this graduation design is the design of a steel plant steel UASB+SBR 4 branch of oily wastewater treatment station water treatment process. According to the water quality of water sewage inlet design of main structures of sewage treatment and water station layout requirements, treated sewage can be discharged. .The wastewater treatment station preliminary design to plete the design specification of a water station design, plane chart, flow chart, elevation drawing, the main building section of not less than 3, the total number of not less than 6 of design drawings. The design to the theme of the iron and steel industry production of oily wastewater, industrial wastewater treatment pared with single contaminant. It mainly uses the UASB+SBR technology mature. The traditional SBR is suitable for industrial wastewater treatment in the intermittent discharge, and covers an area of small high anic load. But because of the sewage of oil concentration is too large, easy to produce the scum. While the UASB method can greatly reduce the oil content in waste water and COD content. So bine the two treatment can have very good effect. Key words： Oil waste water treatment。 UASB。 SBR 目 錄 某鋼鐵廠含油廢水處理工藝 ......................................................................................................................... 1 摘 要 ........................................................................................................................................................ 1 Abstract ....................................................................................................................................................... 2 第一章 工程概況 ........................................................................................................................................ 4 1 設(shè)計依據(jù)及設(shè)計任務(wù) ................................................................................................................................ 5 2 設(shè)計內(nèi)容 ................................................................................................................................................. 5 3 設(shè)計目的 ................................................................................................................................................. 5 4 設(shè)計原則 ................................................................................................................................................. 6 第二章工程設(shè)計 .......................................................................................................................................... 6 1 污水處理站的設(shè)計 .................................................................................................................................... 6 設(shè)計背景 ....................................................................................................................................... 6 設(shè)計進(jìn)出水的水質(zhì) ......................................................................................................................... 6 污水處理工藝 ................................................................................................................................ 6 處理工藝流程選擇 .............................................................................................................. 6 .......................................................................................................................................... 8 隔油池 ........................................................................................................................................... 8 設(shè)計說明 .................................................................................................................................... 8 設(shè)計參數(shù) ............................................................................................................................. 9 設(shè)計計算 ............................................................................................................................. 9 調(diào)節(jié)池 .......................................................................................................................................... 12 設(shè)計說明 ........................................................................................................................... 12 設(shè)計參數(shù) ........................................................................................................................... 12 設(shè)計計算 ........................................................................................................................... 12 提升泵的選用 .............................................................................................................................. 12 一級中和絮凝池 ........................................................................................................................... 13 一級氣浮池 .................................................................................................................................. 14 二級絮凝池 .................................................................................................................................. 15 二級氣浮池 .................................................................................................................................. 16 ........................................................................................
