Izixhobo zokucoca amdaka ze-MBR lelinye igama le-membrane bioreactor.izixhobo zokucoca amanzi amdaka ezidityanisiweyongetekhnoloji ephucukileyo. Kwezinye iiprojekthi ezineemfuno eziphezulu zokungcola kwamanzi kunye nolawulo oluqinileyo lokungcola kwamanzi, i-membrane bioreactor isebenza kakuhle kakhulu. Namhlanje, iLiding Environmental Protection, umenzi wezixhobo zonyango lwelindle oqeqeshiweyo, uza kukuchazela le mveliso ngokusebenza kakuhle okugqwesileyo.
Inxalenye ephambili yeIzixhobo zokucoca amanzi amdaka ze-MBRyi-membrane. I-MBR yahlulwe yangamaqela amathathu: uhlobo lwangaphandle, uhlobo olungaphantsi kwamanzi kunye nohlobo oludibeneyo. Ngokwendlela i-oksijini efunekayo ngayo kwi-reactor, i-MBR yahlulwe yangamaqela angama-aerobic kunye nohlobo lwe-anaerobic. I-Aerobic MBR inexesha elifutshane lokuqalisa kunye nesiphumo esihle sokukhupha amanzi, esinokuhlangabezana nomgangatho wokusetyenziswa kwakhona kwamanzi, kodwa imveliso ye-sludge iphezulu kwaye ukusetyenziswa kwamandla kukhulu. I-Anaerobic MBR inokusetyenziswa kwamandla aphantsi, imveliso ye-sludge ephantsi, kunye nokuveliswa kwe-biogas, kodwa kuthatha ixesha elide ukuqala, kwaye isiphumo sokususa ukungcola asilunganga njenge-aerobic MBR. Ngokwezixhobo ezahlukeneyo ze-membrane, i-MBR inokwahlulwa ibe yi-microfiltration membrane MBR, i-ultrafiltration membrane MBR njalo njalo. Izinto ze-membrane ezisetyenziswa rhoqo kwi-MBR zii-microfiltration membranes kunye ne-ultrafiltration membranes.
Ngokwendlela ezisebenzisana ngayo iimodyuli ze-membrane kunye nee-bioreactors, i-MBR yahlulwe yaba ziintlobo ezintathu: "i-aeration MBR", "i-separation MBR" kunye ne-"extraction MBR".
I-Aerated MBR ikwabizwa ngokuba yiMembrane Aerated Bioreactor (MABR). Indlela yokungenisa umoya yale teknoloji ingcono kunendlela eqhelekileyo yokungenisa umoya webhamuza elikhulu elinemingxuma okanye elinemingxuma emincinci. I-membrane engena ngegesi isetyenziselwa ukuhambisa umoya ngaphandle kwebhamuza ukuze inike ioksijini, kwaye izinga lokusetyenziswa kweoksijini liphezulu. I-biofilm kwi-membrane ephefumlayo idibana ngokupheleleyo nelindle, kwaye i-membrane ephefumlayo inika ioksijini kwiintsholongwane ezinamathele kuyo, kwaye iyonakalisa ngokufanelekileyo ungcoliseko olusemanzini.
Uhlobo lokwahlulwa kwe-MBR lukwabizwa ngokuba yi-MBR yokwahlulwa kwe-solid-liquid. Ludibanisa iteknoloji yokwahlulwa kwe-membrane kunye neteknoloji yendabuko yonyango lwebhayoloji yamanzi amdaka. Ukusebenza kakuhle kokwahlulwa kwe-solid-liquid. Kwaye ngenxa yokuba umxholo we-activated sludge kwi-aeration tank uyanda, ukusebenza kakuhle kwee-biochemical reactions kuyaphucuka, kwaye ungcoliseko lwezinto eziphilayo luyawohloka ngakumbi. Uhlobo lokwahlulwa kwe-MBR lusetyenziswa kakhulu kwiiprojekthi zokucoca amdaka e-MBR.
I-Extractive MBR (EMBR) idibanisa inkqubo yokwahlulwa kwe-membrane kunye nokugaya okungeyo-aerobic. Ii-membranes ezikhethiweyo zikhupha iikhompawundi ezinetyhefu emanzini amdaka. Ii-microorganisms ezingeyo-aerobic ziguqula izinto eziphilayo emanzini amdaka zibe yi-methane, igesi yamandla, kwaye ziguqula izondlo (ezifana ne-nitrogen kunye ne-phosphorus) zibe ziifom ezininzi zeekhemikhali, ngaloo ndlela ziphucula ukubuyiswa kwezixhobo emanzini amdaka.
