Membrane Module Hom
MBR daim nyias nyias feem ntau muab faib ua peb hom: hollow fiber ntau daim nyias nyias, daim nyias nyias nyias, thiab cov ntaub qhwv lub qhov txhab. Hollow fiber ntau yog cov siv dav tshaj plaws, uas muaj cov ntim ntim siab thiab cov hneev taw me me, tab sis lawv muaj feem ntau ua rau cov membrane fouling. Pav ca daim nyias nyias muaj lub zog muaj zog thiab muaj zog tiv thaiv - fouling muaj peev xwm, ua rau lawv haum rau siab - load lossis complex dej zoo ib puag ncig. Cov kab mob kis kab mob feem ntau siv rau hauv cov xwm txheej tshwj xeeb sib cais thiab tsis tshua siv hauv MBR systems.
Txheej Txheem
MBRs tuaj yeem muab faib ua submerged MBRs thiab sab nraud MBRs. Submerged MBRs tso cov membrane module ncaj qha rau hauv cov roj ntsha reactor, ua dej los ntawm txoj kev nqus. Lawv yog cov compact, muaj tsawg zog noj, thiab tam sim no yog hom mainstream. Sab nraud MBRs, ntawm qhov tod tes, tso lub membrane module sab nraum lub reactor, siv lub twj tso kua mis circulating mus thawb cov cawv sib xyaw rau hauv daim nyias nyias. Lawv tswj tau yooj yim dua tab sis muaj kev siv hluav taws xob ntau dua thiab tsim nyog rau kev kho cov dej siab siab -concentration lossis tshwj xeeb cov dej khib nyiab.
Kev siv thiab kev ua haujlwm
MBRs kuj tuaj yeem muab faib ua aerobic MBRs, anaerobic MBRs, thiab hybrid MBRs. Aerobic MBRs yog siv rau kev kho dej khib nyiab nrog kev ua haujlwm siab; anaerobic MBRs yog tsim rau cov dej khib nyiab nrog cov organic loads siab thiab tuaj yeem ua tiav lub zog rov qab (xws li biogas); thiab MBRs sib xyaw ua ke ua ke ntau yam txheej txheem los txhim kho nitrogen thiab phosphorus tshem tawm lossis kho cov dej tsis zoo.
