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。

㈦ 污水方面的英語翻譯
生物轉盤小試試驗系統
生物轉盤系統以經預處理的污水為研究對象,有機負荷為0.03 kg COD/m3 /day。污水分析結果如表1和圖9所示。出水COD濃度范圍為80~303mg/L,平均值為144mg/L,BOD出水濃度范圍為30~146mg/L,平均值為73mg/L。油脂類出水濃度范圍為5~66mg/L,平均值為20.9mg/L。平均總懸浮物濃度為23.6mg/L。根據已有數據可知,經處理的污水可以達到埃及法律規定的標准,該標准規定了排入污水處理廠的工業污水的流量。
厭氧處理系統
試驗期間,UASB反應器以經預處理的污水為研究對象,試驗控制兩個有機負荷,分別為6.8 kgCOD/m3 .d和9 kgCOD/m3 .d。水力停留時間分別控制在8h和6h,實驗結果如圖10所示。由數據可知,將有機負荷從6.8提高到9 kgCOD/m3 .d不會對系統COD去除效果產生影響,兩有機負荷條件下的COD平均去除率分別為60%和61%。相應的進水COD分別為1045和1038 mgO2 /l(如表1所示)。負荷變化也沒有對BOD去除效果產生影響,BOD平均去除率分別為71%和73%。剩餘懸浮固體分別為43和57 mg SS/l,根據已有結果,建議厭氧處理的水力停留時間為6小時,該值符合埃及法律規定的排入污水處理廠的工業廢水的規定標准。

DSTE TYPE DOMESTIC SEWAGE TREATMENT EQUIPMENT
OPERATION INSTRUCTIONS
Operation instructions to the DSTE
I Use and scope
This set is mainly used to treat the domestic sewage or some kind of instrial waste water, such as the waste water from the restaurant , sanatorium, or school, etc.
II. Treatment Technology
This DSTE set is mainly adopt the method of the Biomembrane method to deal with the waste water, it is a quite mature method to remove the NH4-N content in the water nowadays, the parameter of the water quality is designed according to the waste quantity containing in the raw water:
Waste intake average parameter
BOD5≤250mg/l
CODcr≤400mg/l
NH3-N≤40mg/l
SS≤300mg/l
Grease≤40mg/l
Effluent average parameter
BOD5≤20mg/l
CODcr≤100mg/l
NH3-N≤15mg/l
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
