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.

處理污水,造福人類
Sewage, the benefit of mankind
隨著科學技術的進步,幾乎每個城市都有許多的工廠,工廠里每天排出的污水都污染了許多江河、湖泊,導致大部分的魚蝦中毒死亡;同時也威脅這自然界里的生物和人類的安危,對人類的生活造成了極大的影響。
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.
我時常幻想著,假如這些污水經過處理,變成干凈的、能飲用的水,那該多好啊!於是我就想到了需要一種能隨意變大變小的「污水處理儀器」,我把它簡稱為「處污器」。它可以放在家裡、學校里、也可以安裝在工廠里。這個「處污器」是個正方形,外殼是一種踩不爛壓不扁的塑料;它的心臟是由一塊伸縮自如且永久使用的過濾網,一個具有除臭功能且永不變形的旋轉筒和一片微型的智能電動晶元組成。這個「處污器」的電是用之不竭的,只要有一絲光亮,它就立刻把光能轉化為電能,非常環保。這個「處污器」可以自動計算需要排出的污水量,然後根據排污量來改變自己的大小。比如:一間造紙廠每天生產一噸紙,只要你輕輕按紅色按鈕,它就自動計算出這間工廠的排污量,根據排污量把自己變大。再輕輕一按綠色按鈕,「處污器」馬上開始工作。污水流經入口的過濾網,所有的大大小小的垃圾就會被過濾掉。沒有垃圾的污水直接流入旋轉筒,旋轉筒不停地轉動去除臭味,再凈化。同時,它會加入人體所需要的礦物質和微量元素,然後再通過出口排出來。這些經過處理的水非常神奇,人們喝了既可以美容又可以強身健體,少生病。動物喝了會更肥壯,再兇猛的動物喝了也會變得善良可愛。這些水用來澆灌禾苗,稻穀的產量會更高。這個「處污器」放在家裡的時候,它會自動變小。家裡的生活用水經過「處污器」可以循環利用。這樣,我們不但達到了節約用水的目的,還保護了地球的生態環境。想到這里,我彷彿就生活在一個綠樹成蔭、鳥語花香、物產豐富、山清水秀……沒有一絲污染的國家裡。
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.
想到這里,我驚醒了,我想:這絕不是幻想的,這是我的夢想、理想。同學們,讓我們行動起來,一起努力,保護環境,節約用水,珍惜水資源,處理污水,造福人類,為現實吧!
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!

3.醫療污水的治理方法
3medical sewage treatment method
醫院污水處理,通常包括一級處理和二級處理。一般地說,若處理後出水排入市政下水道,通常只進行一級處理;若處理後出水直接排入河道,則需進行一級處理和二級處理;對排放標准嚴的地區,為防止水體的富營養化,需進行除磷脫氮三級處理。對酸性廢水、洗相廢水、放射性污水等特殊的醫院污水,應進行嚴格的收集和處理。有些地區為緩解供水緊張的矛盾,已進行醫院污水的深度處理和循環利用。實際採用何種方式處理醫院污水,應綜合考慮污水的來源、污水的流向及當地的供水情況等多方面因素。另外,醫院污水處理一個非常重要的方面,就是必須進行消毒處理,以殺滅各種病原微生物。
Hospital sewage treatment, usually including a stage and two stage treatment. Generally speaking, if the treated water is discharged to a municipal sewer, usually only primary treatment; if the treated water is discharged directly into the river, need to carry on a treatment and two stages of treatment; the emission standard is strict region, in order to prevent the eutrophication of water bodies, need for nitrogen and phosphorus removal of three stages of treatment.

2.城市生活污水治理方法
2city sewage treatment method
針對城市生活污水,可以進行以下處理:
According to the city sewage, can be the following processing:
將城市生活污水輸送到城市周圍的農村,利用農村廣闊的土地來凈化城市生活污水。將是一勞永逸與一舉多得的好方法。以日供應生活用自來水100W立方的大中型城市為例:普通的污水處理設施造價1000元/立方。建設成本10億,年運營成本100W立方/天×365×0.5元/立方=1.8億.採用土壤凈化法建設成本1000元/立方,年運營成本100W立方/天×365×0.1元/立方=0.4億. 同時年節約農用水資源3.6億立方,節約化肥約1萬噸/年,減少農葯用量5噸/年,綜合效益可觀。
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。
