1.4工艺简介
采用A/A/O处理工艺
重庆市某污水处理厂二期处理程度为一级处理、二级生物处理、消毒及污泥处理,执行中华人民共和国国家标准GB8978—1996《污水综合排放标准》中的一级标准,即:BOD5≤20mg/1,SS≤20mg/1,CODcr≤60mg/1,NH3-N≤15mg/1,TP≤0.5mg/1。
该污水处理厂采用A/A/O生化处理工艺。它是在A/O工艺基础上增加了一个缺氧区,具有同步脱氮除磷的功能。
A/A/O工艺处理污水首先进入厌氧区,兼性厌氧发酵细菌将污水中可生物降解的有机物转化为VFA(挥发性脂肪酸类)这类低分子发酵中间产物。而聚磷菌可将其体内存储的聚磷酸盐分解,所释放的能量可供好氧的聚磷菌在厌氧环境下维持生存,另一部分能量还可供聚磷菌主动吸收环境中的VFA类低分子有机物,并以PHB(聚羟β丁酸)的形式在其体内储存起来。随后污水进入缺氧区,反硝化菌就利用好氧区回流混合液带来的硝酸盐,以及污水中可生物降解有机物作碳源进行反硝化,达到同时降低BOD5与脱氮的目的。接着污水进入曝气的好氧区,聚磷菌在吸收、利用污水中残剩的可生物降解有机物的同时,主要是通过分解体内储存的PHB释放能量来维持其生长繁殖。同时过量的摄取周围环境中的溶解磷,并以聚磷的形式在体内储积起来,使出水中溶解磷浓度达到最低。而有机物经厌氧区、缺氧区分别被聚磷和反硝化细菌利用后,到达好氧区时浓度已相当低,这有利于自养型硝化菌的生长繁殖,并通过硝化作用将氨氮转化为硝酸盐。非除磷的好氧性异养菌虽然也能存在,但他在厌氧区中受到严重的压抑,在好氧区又得不到充足的营养,因此在与其他生理类群的微生物竞争中处于相对劣势。排放的剩余污泥中,由于含有大量能超量储积聚磷的聚磷菌,污泥含磷量可以达到6%(干重)以上。从以上分析可以看出A/A/O工艺具有同步脱氮除磷的功能。
A/A/O工艺的优点是厌氧、缺氧、好氧交替运行,可以达到同时去除有机物、脱氮、除磷的目的,而且这种运行状况丝状菌不宜生长繁殖,基本不存在污泥膨胀问题。A/A/O工艺流程简单,总水力停留时间少于其他同类工艺,并且不需外加碳源,缺氧、缺氧段只进行缓速搅拌,运行费用低。
雨、污水经过上述处理合格,符合国家排放标准的污水直接排入长江。

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.
