By aeration zone in the downstream of the aerator, water turbulence state into a state of advection, maintained at a minimum velocity of flow, ensure that activated sludge in a suspended state ( m/s) average velocity. Microbial oxidation process consumes dissolved oxygen in water, until the value to zero in the DO, mixture in hypoxia state. 3. The CD method and application widely in the largespan tunnel, the CRD construction method in this System, BOD degradation is a continuous process, nitrification and denitrification occurred in the same pool. Because of the limitation of structure of the oxidation ditch can be effective for BOD, but phosphorus removal denitrification ability is limited. Carrousel Moseley oxidation ditch the influence factors of biological nitrogen removal Influence factors of phosphorus removal from Carrousel Moseley oxidation ditch is primarily a sludge age, nitrate concentration and substrate concentration. Research shows that when the total sludge age of 8 ~ 10 d, the lion39。 The sludge age slightly long, sludge aging, also easy to produce foam. With surface spray water or remove foam deforming agent, deforming agent monly used engine oil, kerosene, silicone oil, turnover of ~ mg/L. By increasing the sludge concentration in aeration or reduced air, also can effectively control the bubble. When the wastewater contains surface active material is large, easily removed by foam separation process or other method in advance. Also can consider adding a set of oil removal device. But the most important is the better water management, reduce the high oilbearing wastewater and other toxic wastewater into. Sludge upfloating problem When the oil content in waste water is too large, qualitative light, the whole System in the process of operation can39。 Denitrification is found, should reduce air, increasing the backflow or mud。 Chlorine bleaching powder and liquid (% ~ % in dry sludge dosing), inhibit filamentous fungi reproduction, bined with water sludge bulking control. Bubble problem Due to water with a large number of oil, processing System can39。[14]，化學工業(yè)出版社，2003[7]2002感謝所有幫助過我的人！尤其對各門專業(yè)基礎課及專業(yè)課有了更深的認識，為我以后的學習和幫助有了堅強的基礎，也為我更好的從事本專業(yè)工作樹立了信心。根據設計資料，水量，以及泰安市的經濟狀況，選用A2/O工藝較為適合。設計的主要內容包括該處理廠的污水及污泥處理工藝的比選確定，主要處理構筑物的設計計算兩大部分。3)污水流經量水設備的水頭損失。(3)在作高程布置時，還應注意污水流程與污泥流程積極配合。 (5)需要排放的處理水，在常年大多數時間里能夠自流排放水體。(1) 處理構筑物的布置應緊湊，節(jié)約土地并便于管理；(2) 處理構筑物的布置應盡可能按流程順序布置，以避免管線迂回，同時應充分利用地形以減少土方量；(3) 經常有人工作的地方如辦公、化驗等用房應布置在夏季主導風的上風向，在北方地區(qū)也應考慮朝陽，設綠化帶與工作區(qū)隔開；(4) 構筑物之間的距離應考慮敷設管渠的位置，運轉管理的需要和施工的要求，一般采用5—10m；(5) 污泥處理構筑物應盡可能布置成單獨的組合，以備安全，并方便管理；(6)變電所的位置應設在耗電量大的構筑物附近，高壓線應避免在廠內架空敷設；(7) 污水廠應設置超越管以便在發(fā)生事故時，使污水能超越一部分或全部構筑物，進入下一級構筑物或事故溢流管；(8) 污水和污泥管道應盡可能考慮重力自流；(9) 在布置總圖時，應考慮安排充分的綠化地帶，為污水處理廠的工作人員提供一個優(yōu)美舒適的環(huán)境； (10) 總圖布置應考慮遠近期結合，有條件時可按遠景規(guī)劃水量布置，將處理構筑物分為若干系列分期建設。在每根干管上設5對配氣豎管，共10條配氣豎管，全曝氣池共設40條配氣豎管。 池總寬度：B=A/h2=,有效水深h2=；設計n=2格，,() 沉砂斗容積：=其中T＝2d，X＝3m3/106m3 每個沉砂斗的容積(V0)設每一分格有2格沉砂斗，則 沉砂斗各部分尺寸：設貯砂斗底寬b1＝；斗壁與水平面的傾角60176。1．設計參數：柵前流速v1=，過柵流速v2=柵條寬度s=，格柵間隙e=10mm，格柵傾角α=60176。表2—1 兩種污泥濃縮方法比較項目方案一方案二主要構筑物污泥貯泥池 濃縮、脫水機房污泥濃縮池 脫水機房主要設備濃縮池刮泥機濃縮池刮泥機、脫水機占地面積小大絮凝劑總用量?≤對環(huán)境的影響小大總土建費用小大總設備費用一般稍大由上表可見方案一優(yōu)于方案二，因此本工程污泥處理工藝選用污泥機械濃縮，機械脫水。本設計設置隔板式接觸池和配套的加氯、貯氯設施。流入裝置由配水槽、擋流板組成，流出裝置由流出槽與擋板組成，緩沖層的作用時避免已沉污泥被水流攪起以及緩解沖擊負荷，污泥區(qū)起貯存、濃縮和排泥作用，排泥方式有靜水壓力法、機械排泥法。 本設計的具體工藝流程如下圖：圖 2—4 A2/O 工藝流程圖 污水處理工藝1. 格柵本污水處理廠設置粗、細兩道格柵。優(yōu)點：(1) 水力停留時間較短，總占地面積較?。?2) 不易出現污泥膨脹，出水水質較好；(3) 用于大型污水廠時運行費用較低；缺點：(1) 污泥需進行內回流，能耗較高；(2) 污泥滲出液需化學除磷；(3) 沼氣回收經濟效益差。污水和活性污泥的混合液在廊道中不停地循環(huán)流動，其水力停留時間一般較長，為15—16h, 泥齡長達15—30天，氧化溝工藝屬于改進的延時曝氣活性法。SBR工藝實現了在同一反應器內完成一系列工序，其主要工序包括：流入工序：注入原污水反應器，注滿后進行反應，注水方式有單純注水，曝氣，緩速攪拌三種。 設計要求要求學生進行污水處理廠的初步設計。A2/O法又稱AAO法，是英文AnaerobicAnoxicOxic第一個字母的簡稱（厭氧缺氧好氧法），是一種常用的二級污水處理工藝，可用于二級污水處理或三級污水處理，以及中水回用，具有良好的脫氮除磷效果。s quality of life and health level。因此，必須建立一座生活污水處理廠。某城鎮(zhèn)污水處理廠初步設計 洛陽理工學院畢業(yè)設計（論文）靈寶市污水處理廠初步設計摘 要水是人類的生命之源，它孕育和滋養(yǎng)了地球上的一切生物，并從各個方面為人類服務。如不及時對產生的污水進行治理，那么靈寶市的水環(huán)境污染將嚴重下去，整個市區(qū)的生活環(huán)境和生態(tài)平衡都將受到更為嚴重的破壞，而這一切的恢復將是十分緩慢的，要為之付出的代價也十分昂貴。s life and industrial and agricultural production is increasing, so protect and cherish water resources, is a mon responsibility of society as a whole. So water is the foundational natural resource and strategic economic resources, water resources security belongs to resources and economic security. Since the 80 s, a new process for biological treatment of wastewater in the research, development and application, it has been great progress in worldwide, and led to many new types of wastewater biological treatment technology. Some of these new techniques has got good application in practical engineering at home and abroad, some of which have been showing its good application prospect, receive the attention of researchers and engineers and is being constantly indepth study, their mon characteristic is high efficiency, stability, energy saving, and has the versatility of pollutant removal, most has the depth of processing such as nitrogen and phosphorus in good efficiency, and is developing in the direction of the automation control. In recent years, With the economic development of LingBao, population and industrial output also increased, the living water and industrial water demand is increasing dramatically, so will cause the increased amount of sewage, a series of water
