Gabatarwa kan aiwatar da tsarin MBR na fasahar kulawa da keɓaɓɓiyar ruwa

Lokaci: 2020-04-13 hits: 59

Membrane bioreactor shine sabon tsari na kula da ilimin halittar ruwa wanda yake kunshe da rabuwa da membrane da fasahar kula da ilimin halittu. Akwai membranes da yawa, ana rarrabasu gwargwadon tsarin rabuwa, gami da membranes dauki, membranes ion, da membranes permeable; gwargwadon yanayin membranes, akwai membranes na halitta (membranes na halitta) da membranes na roba (membranes Organic da meorranic membranes); Ana rarrabe nau'ikan fasali zuwa nau'in lebur, nau'in bututu, nau'in karkace da nau'in fiber mai ɗorewa.


 

1. Matsayin bincike na tsarin MBR a China


Tun daga 1980s, membrane bioreactors sun karu sosai kuma sun zama ɗayan wuraren bincike. A halin yanzu, anyi amfani da fasahar a fiye da kasashe goma kamar Amurka, Jamus, Faransa da Masar, tare da sikelin daga 6m3 / d zuwa 13000m3 / d.


Binciken da kasar Sin ta yi kan MBR bai wuce shekaru goma ba, amma ci gaba yana da sauri sosai. Bincike na cikin gida akan MBR na iya rarrabawa zuwa fannoni da yawa:


1. Binciko hadadden hanyoyin nazarin halittu daban-daban da kuma sassan jikin membrane. Tsarin magani na yanayin halittu yana gudana daga hanyar sludge na kunnawa zuwa tuntuɓar hanyar hadawan abu da iskar shaka, hanyar biofilm, tsari mai haɗawa da haɗuwa da ƙwanƙwasa ƙwayar rai da ƙwaƙwalwar ƙwayar cuta, da kuma tsari na biyu na phobia Oxygen tsari.

2. Bincike kan abubuwan, tsarin aiki da kuma tsarin lissafi wanda ya shafi tasirin magani da fombur fomb, gano yanayin aikin da ya dace da sigogin aiwatarwa, rage fombura kamar yadda zai yiwu, da kuma inganta karfin aiki da kwanciyar hankali na kayan aiki na membrane;

3. Fadada aikin aikace-aikacen MBR, kayan bincike na MBR yana fadada daga ƙazantar cikin gida zuwa ruwa mai lalatarwa na ruwa (matattarar abinci, ruwan sha giyar) da kuma gurbatattun masana'antu na gurɓataccen ruwa babban magani shine gurbataccen gida.

 

2. Siffofin tsari na MBR


Idan aka kwatanta da fasahar kulawa da ruwan sha na gargajiya, MBR yana da manyan halaye kamar haka:


1. Ingantaccen isasshen ruwa mai ratsa jiki, rabe rabuwa ya fi na tanki na gargajiya, ingancin ruwa mai kyau, ingancin daskararren ruwa da lalacewa suna kusa da sifiri, ana iya sake amfani da su kai tsaye, kuma za a iya sake amfani da na shara.

2. The high-efficiency interception function of the membrane allows microorganisms to be completely trapped in the bioreactor, achieving complete separation of the reactor's hydraulic retention time (HRT) and sludge age (SRT), and the operation control is flexible and stable. 

3. Saboda MBR ya haɗu da tanki na gargajiya na gargajiya da kuma tanki na sirinji na ɗakunan shan ruwa zuwa ɗayan, kuma ya maye gurbin duk wuraren fasaha na kula da ilimin manyan makarantu, zai iya rage ƙasa mai faɗi da kuma kiyaye jarin injin ƙasa.

4. Ingantarwa zuwa ga kutsawa da haifuwa na ƙwayoyin nitrifying, tsarin yana da ingantaccen ingantaccen nitrification. Hakanan yana iya samun ayyuka na lalata da kuma lalata abubuwa ta hanyar sauya yanayin aiki.

5. Tun da shekarun laka na iya yin tsawo, lalacewar ingantattun kwayoyin halitta ke inganta sosai.

6. Ana amfani da injin din wuta a yayin da ake daukar nauyin girma, mara nauyi a jiki, da kuma shekarun tsufa. Ragowar abubuwan da ke fitarwa suna da ƙarancin gaske. Tunda shekarun tsufa zasu iya zama tsawon lokaci, a mahangar, za a iya samun zubarwar sifili.

7. Tsarin ya fahimci sarrafa PLC, sauƙin aiki da gudanarwa.



3. Abun haɗin tsari na MBR


Mafi yawan abubuwan da aka ambata da sunan membrane-bioreactor haƙiƙa ma'anar kalma ce ta nau'ikan masu sakewa:


1. Average membrane-bioreactor (Aeration Membrane Bioreactor, AMBR);

2. Membrane-bioreactor (Extractive Membrane Bioreactor, EMBR);

3. Maganin rabuwa mai-ruwa-mai-rarrabe-bioreactor (Solid / Liquid Separation MembraneBioreactor, SLSMBR, wanda ake kira MBR).
