污水處理設(shè)備特點(diǎn)
處理原則
1全過程控制原則。對醫(yī)院污水產(chǎn)生、處理、排放的全過程進(jìn)行控制。
2減量化原則。嚴(yán)格醫(yī)院內(nèi)部衛(wèi)生安全管理體系，在污水和污物發(fā)生源處進(jìn)行嚴(yán)格控制和分離，醫(yī)院內(nèi)生活污水與病區(qū)污水分別收集，即源頭控制、清污分流。嚴(yán)禁將醫(yī)院的污水和污物隨意棄置排入下水道。
3就地處理原。則。為防止醫(yī)院污水輸送過程中的污染與危害，在醫(yī)院必須就地處理。
4分類指導(dǎo)原則。根據(jù)醫(yī)院性質(zhì)、規(guī)模、污水排放去向和地區(qū)差異對院污水處理進(jìn)行分類指導(dǎo)。
5達(dá)標(biāo)與風(fēng)險(xiǎn)控制相結(jié)合原則。**考慮綜合性醫(yī)院和傳染病醫(yī)院污水達(dá)標(biāo)排放的基本要求，同時加強(qiáng)風(fēng)險(xiǎn)控制意識，從工藝技術(shù)、工程建設(shè)和監(jiān)督管理等方面提高應(yīng)對突發(fā)性事件的能力。
6生態(tài)安全原則。**去除污水中有毒有害物質(zhì)，減少處理過程中消毒副產(chǎn)物產(chǎn)生和控制出水中過高余氯，保護(hù)生態(tài)環(huán)境安全。

本公司主要為全國的污水處理廠，大小企業(yè)，小區(qū)，社區(qū)，農(nóng)村，服務(wù)區(qū)，醫(yī)院，鄉(xiāng)鎮(zhèn)衛(wèi)生院，衛(wèi)生服務(wù)中心，食品廠，養(yǎng)殖場、屠宰廠、洗衣廠，煤礦等等部門提供污水處理方案及解決辦法。公司以“專注環(huán)保，用心效勞”為中心價(jià)值，公司以優(yōu)質(zhì)的產(chǎn)品、完善的售后服務(wù)，精益求精、開拓進(jìn)取的務(wù)實(shí)精神服務(wù)于廣大用戶，我們愿意真誠對待每一用戶，希望經(jīng)過我們的程度和不懈努力，重塑青山綠水。 公司不斷秉承以用戶需求為中心，解決客戶問題為原則，深受全國各地需求客戶的*好評，切合實(shí)際的解決了客戶的問題。
膜單元的過濾操作與反沖洗操作可自動或手動控制，當(dāng)膜單元需要化學(xué)清洗操作時，關(guān)閉進(jìn)水閥和污水循環(huán)閥，打開藥洗閥和藥劑循環(huán)閥，啟動藥液循環(huán)泵，進(jìn)行化學(xué)清洗操作，本一體化生物反應(yīng)器采用可編程序控制器(PLC)控制。
色度去除98%，COD去除92%，COD去除97%，總磷去除96%，SS去除98%，加上該設(shè)備不再采用二氧化氯,,次氯酸鈉,漂B粉等做消劑，也不耗自來水，凈化了污染，節(jié)約了資源，保護(hù)了環(huán)境，深受專家，學(xué)者。
一般來說，醫(yī)院污水的平均用水量為每張床位1000L/d左右。若醫(yī)院設(shè)有化糞池，二氧化氯的投加量可控制在25～30ppm。對于中、大型醫(yī)院，建議選用WHQ全自動型二氧化氯發(fā)生器，對于小型醫(yī)院，建議選用WHB半自動型二氧化氯發(fā)生器。醫(yī)院污水的水質(zhì)十分復(fù)雜，一般隨著用水量的增大，相應(yīng)的污染物濃度也越來越高，為緩解這一情況，醫(yī)院污水處理流程應(yīng)盡可能設(shè)計(jì)調(diào)節(jié)池，調(diào)節(jié)池不但可以調(diào)節(jié)水量，消滅高峰負(fù)荷，并可以調(diào)節(jié)水質(zhì)，使其處理效果不會因水質(zhì)變化而受到干擾。
二氧化氯消毒劑的投加點(diǎn)一般選擇在調(diào)節(jié)池之后。為保證取得良好的殺菌效果，污水和消毒劑在接觸消毒池中停留時間一般不應(yīng)小于1小時WH系列二氧化氯發(fā)生器還可根據(jù)流量信號或其他信號自動控制發(fā)生器的運(yùn)行，確保接觸消毒池中二氧化氯的濃度，*殺滅有害微生物。醫(yī)院污水處理主要包括污水的預(yù)處理、物化或生化處理和消毒三部分。為防止病原微生物的二次污染，對污水處理過程中產(chǎn)生的污泥和廢氣也要進(jìn)行處理。
預(yù)處理醫(yī)院污水進(jìn)行預(yù)處理的主要目的是去除污水中的固體污物，調(diào)節(jié)水質(zhì)水量和合理消納糞便，利于后續(xù)處理?；S池用于醫(yī)院污水處理的化糞池主要有普通化糞池和沼氣凈化池。普通化糞池和沼氣凈化池的原理是通過沉淀的作用先將有機(jī)固體污染物截留，然后通過厭氧微生物的作用將有機(jī)物降解。沼氣凈化池處理效率優(yōu)于普通化糞池?；S池的沉淀部分和腐化部分的計(jì)算容積，應(yīng)按《建筑給水排水設(shè)計(jì)規(guī)范》(GBJ15-88)。

Membrane Bioreactor (MBR) is a new water treatment technology which combines membrane separation technology with biological treatment unit. The whole reaction is mainly composed of core membrane module, main reactor, aeration, cleaning and so on. Membrane separation is used instead of secondary clarifier in activated sludge process, which eliminates the return of residual sludge after secondary clarifier concentration in activated sludge process. Compared with MBR process, it also has the following advantages:
Membrane module can realize solid-liquid separation, and the separation effect is better than that of sedimentation tank. It does not need to worry about sludge. The water quality is good and the membrane can be directly reused when municipal sewage is used as water inlet.
Because of the interception of membrane, microorganisms can be completely intercepted in the bioreactor, and the hydraulic retention time and sludge age can be completely separated, which makes the operation control more flexible.
ZZ
Membrane-bioreactor can operate under high sludge concentration, with strong ability to resist water quality fluctuation, high volume load and small area.
Long sludge age is conducive to the interception and growth of proliferating microorganisms and the nitrification efficiency. Some refractory organic matter can also be retained in the reactor for medium hydraulic retention time, which can effectively detain the microorganisms that decompose refractory organic matter in the reactor, which is conducive to the degradation efficiency of refractory organic matter.
Membrane-bioreactor can be operated under high volumetric load and low sludge load, resulting in low excess sludge yield and sludge treatment cost.
The construction period is short, the construction cost is low, the installation is flexible, and according to the different treatment scale, it can be flexible, easy and equipment. At the same time, it is more convenient to transform the conventional biological treatment process into MBR.
Easy to realize automatic control, easy to operate.
Compared with the process, membrane-bioreactor has the above seven advantages, but conceptually MBR has a higher investment and construction cost. However, with the increase of land price, the decrease of membrane module price and the performance of membrane, the investment of membrane-bioreactor has been comparable to that of conventional process. When applied to the upgrading and transformation of existing process, the investment can even be lower than that of conventional process.
At present, membrane-bioreactor has been widely used in small-scale sewage treatment in areas with high water quality requirements and small area, which reflects the advantages that conventional treatment process can not replace.
