MBBR yog Moving Bed Biofilm Reactor
Lub ntsiab lus MBBR MBBR yog txhawm rau nce cov biomass thiab hom nyob rau hauv kev ntxiv qee qhov kev ncua ntawm kev kho kom zoo ntawm cov reactor. Vim tias qhov ntom ntom ntawm cov muab tub lim yog ze rau ntawm cov dej, nws yog tov nrog dej thaum lub sij hawm aeration, thiab ib puag ncig rau kev loj hlob microbial yog roj, kua thiab khoom. Kev sib tsoo thiab shear cuam tshuam ntawm cov cab kuj hauv dej ua rau cov pa npuas ua kom zoo dua thiab ua rau kev siv cov pa oxygen. Tsis tas li ntawd, txhua tus cab kuj muaj cov kab mob sib txawv sab hauv thiab sab nraud, qee cov kab mob anaerobic lossis cov kab mob facultative loj hlob sab hauv, thiab sab nraud yog cov kab mob trophic zoo, yog li txhua tus cab kuj yog ib qho me me reactor, kom nitrification cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv denitrification muaj nyob rau tib yam. lub sijhawm, txhawm rau txhim kho kev kho mob.
Cov txheej txheem MBBR muaj qhov zoo ntawm ob qho tib si lub txaj fluidized thiab lom oxidation txoj kev, thiab yog ib txoj kev kho dej phwj tuaj tshiab, uas tso siab rau cov aeration thiab dej ntws hauv lub aeration tank ua rau cov cab kuj nyob rau hauv lub xeev fluidized, thiab tom qab ntawd cov ntaub ntawv raug tshem tawm cov sludge thiab txuas biofilm, uas ua rau lub txaj txav biofilm siv tag nrho cov reactor qhov chaw, muab tag nrho ua si rau qhov zoo ntawm ob qho tib si theem thiab lub cev raug tshem tawm theem, thiab ua kom nws txhim kho nws lub zog thiab tsis txhob muaj qhov tsis muaj zog, thiab sib ntxiv. Tsis zoo li cov khoom siv niaj hnub, cov khoom siv raug tshem tawm yog hu ua "mobile biofilms" vim tias lawv nyob hauv kev sib cuag nrog cov dej phwj tuaj.
