【正文】 西安工程大學(xué)本科畢業(yè)設(shè)計（論文） 摘 要 本次畢業(yè)設(shè)計的題目是黑龍江大慶市 萬噸 /日 污水處理工藝設(shè)計工藝。主要任務(wù)是完成個該地區(qū)污水的處理設(shè)計。該污水處理廠工程，規(guī)模為 萬噸 /日。 OA/2 工藝的生物處理部分由厭氧池、缺氧池和好氧池組成。厭氧池主要功能是釋放磷 ,同時部分有機物進行氨化。缺氧池的主要功能是脫氮。好氧池是多功能的能夠去除 BOD、硝化和吸收磷。 該污水廠的污水處理流程為：從泵房到沉砂池，進入反應(yīng)池，進入輻流式二次沉淀池，再進入 接觸池 池，最后出水；污泥的流程為：從反應(yīng)池排出的剩余污泥進入集泥配水井，再由污水泵送入濃縮池，再進入 貯泥 池，最后進入脫水機房脫水，最后外運處置。 關(guān)鍵詞 ： OA/2 脫氮除磷 工藝流程西安工程大學(xué)本科畢業(yè)設(shè)計（論文） Abstract The topic of this graduate design is about the design of the sewage disposal plant in the area of HEI LONG JIANG. The technics of the plant is the Anaerobic Anoxic Oxic. The construction of this plant is 155000 tones a ditch and unoxidize pool are two important part and water flows into three ditchs in turn, also Toxidize ditch plays the role of secondary settling. The unoxidize pond release phosphorus. Along with aeration distance, the dissolved oxygen density reduces. . Namely appears the nitration and the counter nitration process in succession , get the result of denitrogenation. At the same time the fine oxygen district absorbs the phosphorus, get the result of getting rid of phosphorus. The process of the sewage in the plant is that: The sewage runs from pump house to sand sinking pond, enters the pond of sedimentation tank, enters disinfection pond, then enters calculation trough ,at last lets out. The process of the sludge is that: Surplus sludge from the sedimentation tank enters concentration pond, enters digestion pond , enters automatically translated text: then enters automatically translated text:, at last it is carried out of the plant. KEY WORDS： The AnaerobicAnoxicOxic。 Taking off the nitrogen and the phosphorus。 西安工程大學(xué)本科畢業(yè)設(shè)計（論文） 目 錄 前言 ................................................................................................................................ 1 第 1 章 設(shè)計任務(wù) ........................................................................................................ 2 設(shè)計原始資料 .......................................................................................................... 2 自然地理環(huán)境 ....................................................................................................... 2 氣候條件 ............................................................................................................... 2 設(shè)計進出水水質(zhì) ................................................................................................... 3 設(shè)計要求 .................................................................................................................. 3 設(shè)計內(nèi)容 .............................................................................................................. 4 任務(wù)要求 .............................................................................................................. 5 第 2 章 污水處理廠設(shè)計 ............................................................................................ 6 污水處理廠址選擇 ................................................................................................. 6 污水污泥處理工藝選擇 ......................................................................................... 6 水質(zhì)指標(biāo) ............................................................................................................... 6 污水、污泥處理工藝選擇 ................................................................................... 7 第 3 章 污水處理系統(tǒng)設(shè)計計算 .............................................................................. 11 格柵的計算 ........................................................................................................... 11 設(shè)計要求 ............................................................................................................ 11 中格柵的設(shè)計計算 ............................................................................................ 11 細格柵的設(shè)計計算 .......................................................................................... 15 沉砂池的設(shè)計計算 ............................................................................................. 17 西安工程大學(xué)本科畢業(yè)設(shè)計（論文） 曝氣沉砂池設(shè)計參數(shù) ...................................................................................... 17 曝氣沉砂池設(shè)計計算 ...................................................................................... 18 初次沉淀池的設(shè)計計算 ....................................................................................... 25 設(shè)計要點 ............................................................................................................ 25 初次沉淀池的設(shè)計（為輻流式） .................................................................... 26 OA/2 反應(yīng)池的設(shè)計計算 .................................................................................. 28 設(shè)計要點 ............................................................................................................. 28 設(shè)計計算 ............................................................................................................. 29 曝氣系統(tǒng) ............................................................................................................ 34 二沉池的設(shè)計計算 ............................................................................................... 40 設(shè)計要求 ............................................................................................................ 40 二次沉淀池的設(shè)計 ............................................................................................. 41 消毒設(shè)施設(shè)計計算 ............................................................................................... 45 消毒設(shè)施 .......................................................................................................... 45 計量設(shè)備 .......................................................................................................... 48 第 4 章 污泥處理系統(tǒng)設(shè)計計算 .............................................................................. 53 濃縮池的設(shè)計計算 ............................................................................................... 53 設(shè)計要點
