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.

处理污水,造福人类
Sewage, the benefit of mankind
随着科学技术的进步,几乎每个城市都有许多的工厂,工厂里每天排出的污水都污染了许多江河、湖泊,导致大部分的鱼虾中毒死亡;同时也威胁这自然界里的生物和人类的安危,对人类的生活造成了极大的影响。
With the progress of science and technology, almost every city has many factories, factory every day discharge sewage pollution of many rivers, lakes, cause most of the deaths of fish and shrimp; Also threaten the creatures of the nature and the human safety, caused great impact on human life.
我时常幻想着,假如这些污水经过处理,变成干净的、能饮用的水,那该多好啊!于是我就想到了需要一种能随意变大变小的“污水处理仪器”,我把它简称为“处污器”。它可以放在家里、学校里、也可以安装在工厂里。这个“处污器”是个正方形,外壳是一种踩不烂压不扁的塑料;它的心脏是由一块伸缩自如且永久使用的过滤网,一个具有除臭功能且永不变形的旋转筒和一片微型的智能电动芯片组成。这个“处污器”的电是用之不竭的,只要有一丝光亮,它就立刻把光能转化为电能,非常环保。这个“处污器”可以自动计算需要排出的污水量,然后根据排污量来改变自己的大小。比如:一间造纸厂每天生产一吨纸,只要你轻轻按红色按钮,它就自动计算出这间工厂的排污量,根据排污量把自己变大。再轻轻一按绿色按钮,“处污器”马上开始工作。污水流经入口的过滤网,所有的大大小小的垃圾就会被过滤掉。没有垃圾的污水直接流入旋转筒,旋转筒不停地转动去除臭味,再净化。同时,它会加入人体所需要的矿物质和微量元素,然后再通过出口排出来。这些经过处理的水非常神奇,人们喝了既可以美容又可以强身健体,少生病。动物喝了会更肥壮,再凶猛的动物喝了也会变得善良可爱。这些水用来浇灌禾苗,稻谷的产量会更高。这个“处污器”放在家里的时候,它会自动变小。家里的生活用水经过“处污器”可以循环利用。这样,我们不但达到了节约用水的目的,还保护了地球的生态环境。想到这里,我仿佛就生活在一个绿树成荫、鸟语花香、物产丰富、山清水秀……没有一丝污染的国家里。
I often fantasize about, if the wastewater has been treated, can become clean, drinking water, that it would be good! So I was thinking about can need a casual becomes big small "sewage treatment instrument", I put it referred to as the "basin". It can be put in the home, school, also can be installed in the factory. The "basin" is a square, the shell is a kind of trample bad pressure not flat plastic; Its heart is a piece of retractile and permanent use of filter, a deodorization function and never deformation and the rotating drum and a chip of the intelligent electric chip. The "basin" electricity is unlimited, as long as there is light, it immediately to convert light energy into electrical energy, environmental protection very much. The "basin" can automatically calculate need amount of sewage discharge, and then according to the size of the emissions to change itself. For example: a paper mill procing one ton of paper a day, as long as you gently press the red button, it will automatically calculate the emissions from the factory, according to position themselves. Gently press the green button again, "basin" start work immediately. The filter on the sewage through the entrance, all the big and small garbage will be filtered out. No garbage sewage directly into the rotating drum, rotating cylinder kept turning to remove odor, purify again. At the same time, it will join the minerals and trace elements of human need, and then discharged through exports. The treated water is very magical, people drink can not only beauty but it can strengthen physical health, sick less often. Animals drink will be more fat, and then drank the ferocious animals will become kind and lovely. The water used to irrigate the movie, the output of rice is higher. The "basin" at home, it will automatically become smaller. Home after "basin" of domestic water can be recycled. In this way, we not only achieved the purpose of saving water, protect the ecological environment of the earth. Thought of here, I like to live in a tree-lined, charactizing a fine spring day, rich natural resources, beautiful scenery... No any pollution in a country.
想到这里,我惊醒了,我想:这绝不是幻想的,这是我的梦想、理想。同学们,让我们行动起来,一起努力,保护环境,节约用水,珍惜水资源,处理污水,造福人类,为现实吧!
Thought of here, I woke with a start, I thought: this is not fantasy, this is my dream and ideal. Boys and girls, let's action, and work together to protect the environment, save water, cherish water, sewage, and for the benefit of humanity, for real!

针对城市生活污水,可以进行以下处理:

According to the city sewage, can be the following processing:

将城市生活污水输送到城市周围的农村,利用农村广阔的土地来净化城市生活污水。将是一劳永逸与一举多得的好方法。以日供应生活用自来水100W立方的大中型城市为例:普通的污水处理设施造价1000元/立方。建设成本10亿,年运营成本100W立方/天×365×0.5元/立方=1.8亿.采用土壤净化法建设成本1000元/立方,年运营成本100W立方/天×365×0.1元/立方=0.4亿. 同时年节约农用水资源3.6亿立方,节约化肥约1万吨/年,减少农药用量5吨/年,综合效益可观。

The city sewage transported to the city around the country, the use of rural broad land to purification of city sewage. Will be to put things right once and for all and too good method. In order to supply living water cubic 100W is large and medium-sized city for example: common sewage treatment facility cost 1000 yuan / cubic. 1000000000years of construction cost, operation cost of 100W cubic meters / day x 365x 0.5yuan / cubic = 180000000. Using soil decontamination method construction cost of1000 yuan / cubic meters, annual operation cost of 100W cubic meters / day x 365x 0.1yuan / cubic = 40000000. While saving agricultural water resource of 360000000 cubic meters, saving about 10000tons of chemical fertilizer, rece pesticide consumption5 tons / year, integrated benefit is considerable.

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。
