Inqubo yocwaningo nokusetshenziswa kwe-MBR

1. Inqubo yokucwaninga ye-MBR

 

Ngawo-1960, inhlanganisela ye-activated sludge bioreactor kanye ne-cross-flow membrane filtration yabona ukusetshenziswa kwe-MBR ekwelashweni kwamanzi angcolile okokuqala ngqa. Ku-1989, abacwaningi babeka amamojula we-membrane ngaphakathi kwama-bioreactors, beqa inqubekela phambili yama-reactor we-MBR ahlanganisiwe. Kusukela ngama-1990s, ngenxa yokuthuthuka okuqhubekayo kwe-membrane flux, ubuchwepheshe bokulawula ukungcola kwe-membrane nezinto zokwakha ulwelwesi nazo zithuthukiswe kakhulu, izindleko zama-membrane bioreactors ziya ngokuya zehla, futhi le nqubo iye yanakwa kancane kancane. Kusukela ngo-2006, inani eliphelele lama-membrane bioreactors asetshenziswe emhlabeni wonke lifinyelele ezigidini ezingama-US $ 216. Ngokukhulumayo, intuthuko yaseChina iqale emuva kwesikhathi, kepha ukukhula kwayo kuyashesha, futhi izinga lokukhula kwayo lishesha kakhulu kunezinga elijwayelekile lokukhula emhlabeni. Okwamanje isetshenziswa kahle ekwelashweni kwendle okuningi okusebenzayo.


 

2. Ukusebenza kwe-MBR

 

(1) Ukusetshenziswa kwe-MBR ekwelashweni kokukhucululwa kwendle emadolobheni

 

Ngasekupheleni kweminyaka yama-1990s, ngokuvela kwe-MBR ehlanganisiwe, ukusetshenziswa kwama-membrane reactor ekwelashweni kokukhucululwa kwendle kwasedolobheni kuye kwasungulwa ngokushesha. Ukusuka ngonyaka we-2005, amaphrojekthi we-219 we-MBR wokukhucululwa kwendle aseqediwe eNyakatho Melika. Yize iChina yaqala sekwephuzile, ithuthuke ngokushesha. Njengamanje, kunamaphrojekthi amaningi asebenza noma owakhiwa eChina.

 

(2) Ukusetshenziswa kwe-MBR ekwelashweni kwamanzi amdaka kwezimboni

 

Uma kuqhathaniswa nokwelashwa kokukhucululwa kwendle okwenziwa emadolobheni, i-MBR inezinzuzo eziningi emkhakheni wezokwelapha wamanzi amdaka wezimboni. Ngokwezibalo, i-MBR njengamanje ibangela ama-41% wokuphathwa kwamanzi amdaka kwezimboni, futhi isetshenziswa kabanzi ekuphrinteni nasekudayweni, ekuphekeni, ekuthambiseni i-electroplating, ekuhlanzeni i-oyili, ekudleni, ku-petrochemicals, kubhiya, kwezokwelapha nase-leachate.
