Wannan labarin ya sake nazarin nau'ikan, tarihin bincike, aikace-aikace, fa'ida da raunin da ke tattare da membrane bioreactors, kuma yana gabatar da manyan matsalolin membrane bioreactors, wato membrane fouling and membrane fouling planning Bayar da tunani don aikace-aikacen bincike.

 


A takaice dai gabatarwar membrane bioreactor

 

Membrane bioreactor (MBR) wani sabon nau'in tsarin kula da ruwa ne wanda yake haɗe da fasahar rabuwa da membrane da fasahar sharar ƙwayoyin cuta. Abubuwan haɗinsa sun haɗa da bioreactor, module membrane da tsarin sarrafawa. Daga cikinsu, lalacewar gurɓatattun abubuwa a cikin ƙirar bioreactor galibi yana samar da wuri don tsarin lalata. Kwayar membrane ta ƙunshi membrane da sashi mai goyan baya, wanda shine babban ɓangaren duk abubuwan motsa jiki.

 


Saboda daban-daban membrane da daban-daban haduwar membrane kayayyaki da bioreactors, MBR na iya samun hanyoyi daban-daban na rarrabuwa:

 

1. Dangane da pore na membrane module membrane a cikin bioreactor, za a iya raba reactor na MBR zuwa microfiltration, ultrafiltration, nanofiltration, pervaporation da sauran masu sakewa.

 

2. Dangane da ko ana bukatar aeration a cikin tsarin aiwatar da kwayoyin halitta, ana iya rarrabe shi cikin bioreactor na aerobic membrane da anaerobic membrane bioreactor. Daga cikin su, nau'in aerobic ana amfani dashi ne musamman don kula da ruwan sharar birni da kuma najabin gida, kuma ana amfani da nau'in anaerobic ne don kula da tsaftataccen ruwan gargajiya.

 

3. Dangane da tsari da hanyar tsari na membrane a cikin membrane module, za a iya raba MBR zuwa farantin da nau'in firam, nau'in rauni mai rauni, nau'in bututu mai zagaye, nau'in kyandir da kuma nau'in ƙwayar murfin membrane. Daga cikin su, abubuwan da aka saba dasu sune nau'in farantin karfe da nau'in firam da nau'in fiber m.

 

4. Dangane da sakamakon membrane module, ana iya raba shi zuwa rabuwa MBR, MBA aeration da kuma karin MBR. Mafi yawan nau'in rabuwa ana amfani dashi don cire barbashi da aka dakatar a cikin najasa da kuma cikakke cikakkiyar rabuwa-ruwa mai-kyau. Ana amfani da ita lokacin tashin gwauro don amfani da iskar oxygen mai yawa. Ana amfani da nau'in hakar ne musamman a aikin kula da ruwan sha na masana'antu don kammala hakar da tarin gurɓatattun abubuwa a cikin ruwan sha.

 

5. Dangane da daban-daban jeri na membrane kayayyaki da bioreactors, MBR za a iya raba shi daban da kuma hade membrane bioreactors. Rashin nau'in membrane bioreactor shima ana kiranta yana aiki da membrane bioreactor. Cakuda ruwan mai yana shiga ciki na kwayar ta hanyar matsi. Karkashin aikin matsin lamba, ruwa ya shiga cikin membrane kuma an daskarar da barbashi mai kauri. A cikin nau'in haɗin kai, ana sanya madaidaicin membrane kai tsaye a cikin reactor.
