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。

SS≤70mg/l
Grease≤10mg/l
The main treatment technology flow is as follow:

Kitchen sewage Oil interceptor

Intake of the sewage Bar rack Retention pool Anaerobic tank

sludge recycle

Contact oxidation tank Sediment tank disinfection tank

To disposal sludge tank
The sediment tank is erect style tank, the up-flow velocity is 0.4---0.8mm/s, contact oxidation material is stereoscopic and elastic, the specific surface area of it is 300m2/m3, the O2 supply is designed according to the BOD5 and NH3-N content in the water, and the aeration period will be 6~8 hours.
The time for waste water stay in the anaerobic tank is 2-3 hours, after contact oxidation, the waste water and sludge backflow to the anaerobic, backwater ratio is (100--200%) according to the adjustment. The time the waste water be kept in the sediment tank should more than 1.5~2 hours, sludge in the sediment tank will be exalted to the sludge tank by air waiting for the contact oxidation, then the overflow will backflow to the retention basin retreated, the sludge in the tank would be cleaned periodically.
III Installation
1.Three forms of installation: ⑴underground installation; ⑵half underground installation;⑶on the ground installation. The basement must be flat, if the set is installed underground, the height between the basement and the surface of the ground should adopt the drawing, and make the excavation width exceed 500mm out of the foundation plate , which is better for pipe installation.
2. Everything about pipe installation and connection should be taken into consideration when the set is ready. Make sure the net weight is suit with the crane, and the installation sequence should adopt the designed drawing, tight the screws with the rubber washer so as to connect the pipes, make sure there isn’t any leaking in the conit joint.
3. The install direction and position should be correct, so do the interval between them.
4. Fix the set with the surface of the ground after the installation has been finished, make sure it is firmly fixed, and the set wouldn’t move in the future. Pour in water after finish installation to the full. Make sure there isn’t any leaking on the conit joint, and make sure the set wouldn’t in version or inclined because of rise of the water under the ground.
5. After correct installation, pour some soil into the interval and make it flat, make sure:
⑴ The cover of the manhole should higher than the surface for about 100mm;
⑵ The air intake pipe on the manhole wouldn’t be blocked by the soil.
6. Connect the electrical control wire with the set, pay attention to the running direction of the blower and the submersible sewage pump. The electrical control cabinet couldn’t be kept outdoor, because the sun or rain would destroy the control board.
7. Points of attention:
⑴ The place to install the set could not store up the water when it is raining, ⑵ The water outlet pipes should be 0.4m under the surface of the ground.
⑶ Make sure that there wouldn’t any heavy things on top of it, and no tracks would get through it.
⑷ There should always some waste water in the set to prevent the floatage of the set by the underground water.
IV Examine the set and start before use
Make sure the electrical wires, control panel wires and the voltage are all accord with requirement. The local control cabinet could not only be used to control submersible sewage pumps and the blowers at the same time, but also could monitor itself according to the working condition. It also have the ability to self protect and self alarm, beside that, manual switch and automatic exchange switch are also equipped. To examine the pipes of the pump before start to see whether it is seeping or bibulous or stifled.
The pump of this set is antiblock avusion type pump, the control of two pumps is through the liquid switch in the waste water basin, working pump start to work when the height raised to the start level; the spare pump start when the height raised to the highest level; pump stop working when the height fall to the low level. Check out whether the revolving direction of the blower is correct when it is started.
When the liquid level is lower than the pump starting height, both two pumps stop working. At this time, the blower start to work intermittently, working time should between 0~30 minutes, and the period of the intermittent start should between 0~2 hours.
The control of the sludge discharge in the sediment tank is air boost discharge by the electromagnetic valve, discharging cycle: 2hours/time, discharging time: 5~8minutes/time.
The control of the set should be finished according to the computer designed working procere one time, (only under some special conditions the hand –driven control could be used). If it is necessary, the manual control of the submersible sewage pumps and the blowers and the electromagnetic valve can be realized through turning the switch on or off by hand.
V. The cultivation of the biomembrane
1. The quantity of sewage which entering in the set should accord with the rated flux with no stop.
2. The oxygen volume from the blower should reced to half amount when starting the submersible sewage pump, blower, electromagnetic valve and the CLO2 generator。
3. Observe the material filled in the contact oxidation tank, the biomembrane has finished when a piece of yellow or black dope could be found on the surface. The process costs 7~15 days.
4. The best temperature should be: 15~25℃
5. If the density of the original sewage is to low, it would cost more time to cultivate the biomembrane, so when it is necessary, some kind of furtilizer should be added.
6. The pH value should be kept between 6 and 9, so that the original sewage could reach the step of contact oxidation.
7. When start, pour in small quantity of sewage into the sewage treatment system. After the bilmembrane is finished, Sewage could enter in the system in normal flux.

VI. The management of the operation
1. Turn the blower to the normal position.
2. Let the backflow ratio of the contact oxidation tank reach the best position.
3. Working as designed, often observe the cultivative situation of the biomembrane.
VII. Maintenance and fix the breakdown
1. Make sure that there wouldn’t any solid material content in the sewage, to prevent the block of the pipes.
2. Cover the manhole of the set so as to prevent the droping of some solid material.
3. The pH value should be kept between 6 and 9, in order to keep a better condition for cultivation.
4. Change the lubricating oil in the blower one time every six months.
5. Keep the entrance of the blower unblocked.
6. Fix the breakdown
