1.4工藝簡介
採用A/A/O處理工藝
重慶市某污水處理廠二期處理程度為一級處理、二級生物處理、消毒及污泥處理,執行中華人民共和國國家標准GB8978—1996《污水綜合排放標准》中的一級標准,即:BOD5≤20mg/1,SS≤20mg/1,CODcr≤60mg/1,NH3-N≤15mg/1,TP≤0.5mg/1。
該污水處理廠採用A/A/O生化處理工藝。它是在A/O工藝基礎上增加了一個缺氧區,具有同步脫氮除磷的功能。
A/A/O工藝處理污水首先進入厭氧區,兼性厭氧發酵細菌將污水中可生物降解的有機物轉化為VFA(揮發性脂肪酸類)這類低分子發酵中間產物。而聚磷菌可將其體內存儲的聚磷酸鹽分解,所釋放的能量可供好氧的聚磷菌在厭氧環境下維持生存,另一部分能量還可供聚磷菌主動吸收環境中的VFA類低分子有機物,並以PHB(聚羥β丁酸)的形式在其體內儲存起來。隨後污水進入缺氧區,反硝化菌就利用好氧區迴流混合液帶來的硝酸鹽,以及污水中可生物降解有機物作碳源進行反硝化,達到同時降低BOD5與脫氮的目的。接著污水進入曝氣的好氧區,聚磷菌在吸收、利用污水中殘剩的可生物降解有機物的同時,主要是通過分解體內儲存的PHB釋放能量來維持其生長繁殖。同時過量的攝取周圍環境中的溶解磷,並以聚磷的形式在體內儲積起來,使出水中溶解磷濃度達到最低。而有機物經厭氧區、缺氧區分別被聚磷和反硝化細菌利用後,到達好氧區時濃度已相當低,這有利於自養型硝化菌的生長繁殖,並通過硝化作用將氨氮轉化為硝酸鹽。非除磷的好氧性異養菌雖然也能存在,但他在厭氧區中受到嚴重的壓抑,在好氧區又得不到充足的營養,因此在與其他生理類群的微生物競爭中處於相對劣勢。排放的剩餘污泥中,由於含有大量能超量儲積聚磷的聚磷菌,污泥含磷量可以達到6%(乾重)以上。從以上分析可以看出A/A/O工藝具有同步脫氮除磷的功能。
A/A/O工藝的優點是厭氧、缺氧、好氧交替運行,可以達到同時去除有機物、脫氮、除磷的目的,而且這種運行狀況絲狀菌不宜生長繁殖,基本不存在污泥膨脹問題。A/A/O工藝流程簡單,總水力停留時間少於其他同類工藝,並且不需外加碳源,缺氧、缺氧段只進行緩速攪拌,運行費用低。
雨、污水經過上述處理合格,符合國家排放標準的污水直接排入長江。

1.4工藝簡介採用A/A/O處理工藝重慶市某污水處理廠二期處理程度為一級處理、二級生物處理、消毒及污泥處理,執行中華人民共和國國家標准GB8978—1996《污水綜合排放標准》中的一級標准,即:BOD5≤20mg/1,SS≤20mg/1,CODcr≤60mg/1,NH3-N≤15mg/1,TP≤0.5mg/1。該污水處理廠採用A/A/O生化處理工藝。它是在A/O工藝基礎上增加了一個缺氧區,具有同步脫氮除磷的功能。A/A/O工藝處理污水首先進入厭氧區,兼性厭氧發酵細菌將污水中可生物降解的有機物轉化為VFA(揮發性脂肪酸類)這類低分子發酵中間產物。而聚磷菌可將其體內存儲的聚磷酸鹽分解,所釋放的能量可供好氧的聚磷菌在厭氧環境下維持生存,另一部分能量還可供聚磷菌主動吸收環境中的VFA類低分子有機物,並以PHB(聚羥β丁酸)的形式在其體內儲存起來。隨後污水進入缺氧區,反硝化菌就利用好氧區迴流混合液帶來的硝酸鹽,以及污水中可生物降解有機物作碳源進行反硝化,達到同時降低BOD5與脫氮的目的。接著污水進入曝氣的好氧區,聚磷菌在吸收、利用污水中殘剩的可生物降解有機物的同時,主要是通過分解體內儲存的PHB釋放能量來維持其生長繁殖。同時過量的攝取周圍環境中的溶解磷,並以聚磷的形式在體內儲積起來,使出水中溶解磷濃度達到最低。而有機物經厭氧區、缺氧區分別被聚磷和反硝化細菌利用後,到達好氧區時濃度已相當低,這有利於自養型硝化菌的生長繁殖,並通過硝化作用將氨氮轉化為硝酸鹽。非除磷的好氧性異養菌雖然也能存在,但他在厭氧區中受到嚴重的壓抑,在好氧區又得不到充足的營養,因此在與其他生理類群的微生物競爭中處於相對劣勢。排放的剩餘污泥中,由於含有大量能超量儲積聚磷的聚磷菌,污泥含磷量可以達到6%(乾重)以上。從以上分析可以看出A/A/O工藝具有同步脫氮除磷的功能。A/A/O工藝的優點是厭氧、缺氧、好氧交替運行,可以達到同時去除有機物、脫氮、除磷的目的,而且這種運行狀況絲狀菌不宜生長繁殖,基本不存在污泥膨脹問題。A/A/O工藝流程簡單,總水力停留時間少於其他同類工藝,並且不需外加碳源,缺氧、缺氧段只進行緩速攪拌,運行費用低。雨、污水經過上述處理合格,符合國家排放標準的污水直接排入長江。
1.4 Brief information on processes usedA/AO biological treatment processThe secondary-phase of Chongqing Jiguanshi Treatment Plant utilizes the processes of secondary-level treatment, secondary-level biological treatment, sterilization and sludge disposal. The level I criteria of the Chinese National Standard GB8978-1996: Comprehensive Sewage Discharge Standard, i.e. BOD5≤20mg/1, SS≤20mg/1, CODcr≤60mg/1, NH3-N≤15mg/1, TP≤0.5mg/1.The treatment plant uses the A/AO biological treatment process, which is based on the A/O process with an anaerobic area added to it. It has the simultaneous dehydrogening and desulphoring function.In the A/A/O process, the sewage water is first let into the anaerobic area where the faculiative anaerobic fermenting bacteria convert the biologically recible organic substances in the sewage water into low-molecule intermediate procts such as VPA (volatile fatty acid). The phosphor-gathering bacteria on the other hand is able to discompose the polyphosphates stored in their bodies. The energy thus released may keep the aerobic polyphosphor bacteria alive in the anaerobic environment. The other part of the energy is then used by the polyphosphor bacteria for actively absorbing the VPA type low-molecule organic substances in the environment and store then in their body in the form of PRB. Then the sewage water is let into the anaerobic area and the denitrificating bacteria make use of the nitrate brought by the back-flowing mixture liquid in the aerobic area and the biologically recible organic substances in the sewage water as the source of carbon for denitrification so as to serve the purpose of recing BOD1 ad denitrogening. Then the sewage water enters the aerating aerobic area and the polyphosphor bacteria, while making use of the remaining biologically recible organic substances in the sewage water, keep growing and reprocing by mainly decomposing the PRB stored in their bodies to release energy and at the same time get dissolved phosphor from the surrounding environment and store them in their bodies in the form of polyphosphor so that the concentration of dissolved phosphor in the outlet water is reced to the minimum. The organic substances, after being used by the polyphosphoring and denitriding bacteria in the aerobic and anaerobic areas, are fairly low in content, which is good for the reproction of the self-supporting nitrifying bacteria and the ammonia and nitrogen are converted into nitrate through the nitrifying effect. Though the non-dephosphoring aerobic heterotrophic bacteria may exist, they are in a disadvantaged position in their competition with other microbes because they are severely suppressed in the amoebic area and unable to get sufficient nutrients in the aerobic area. In the remaining sludge drained, the content of phosphor may be more than 6% (dry weight) e to the presence of a great number of polyphosphor bacteria. The above analysis shows that the A/A/O process has the synchronous denitrgening and dephosphoring function.The A/A/O process has the advantage of alternating actions of anaerobic, oxygen deficiency and aerobic. This may serve the purpose of simultaneously removing organic substances, denitrogening and dephosphoring. Furthermore, this operating condition makes it difficult for the filamentous bacteria to grow and reproce, eliminating the problem of sludge expansion. The A/A/O process is simple and the total dwelling time of hydro-force is shorter than that of other processes of similar type. No additional carbon source will be needed and only slow agitation is required ring the hydrogen deficiency period, thus resulting in a low operating cost.Rainwater and sewage water through the above treatment conforms to the relevant national standard in quality and may be directly let into the Yangtze River.
