Lub biofilter -ceramic membrane ua ke cov txheej txheem zoo siv kev tshem tawm cov organic teeb meem thiab ammonia nitrogen los ntawm biofilter (granular activated carbon (GAC) los yog ceramic granule filter), thaum lub sij hawm tom ntej ceramic membrane lim cais cov khoom thiab cov khoom ua kua, ntxiab aging biofilm, tshem tawm turbidity ntawm microorganisms, ua kom muaj kev nyab xeeb thiab ruaj ntseg. kev meej. Ob txheej txheem yog ua ke kom zoo.
Duab: Cov kab mob hauv zej zog muaj pes tsawg leeg ntawm phylum theem hauv cov txheej txheem ceramic ua ke (qhov twg A1 yog dej nyoos, B2 yog ceramic granule biofilter, F1 yog txheej fouling ntawm daim nyias nyias ntawm ceramic granule biofilter-ceramic membrane ua ke txheej txheem, C2 yog GAC biofilter, thiab G1 yog fouling txheej ntawm daim nyias nyias ntawm cov txheej txheem biofilter {GAC}).
Cov duab saum toj no qhia cov kab mob hauv zej zog muaj pes tsawg leeg ntawm qib phylum hauv cov txheej txheem ceramic ua ke. Cov kab mob hauv zej zog muaj pes tsawg leeg ntawm cov dej nyoos sib txawv ntawm cov biofilter, thaum cov kab mob hauv zej zog muaj pes tsawg leeg ntawm biofilter thiab fouling txheej ntawm daim nyias nyias tsis sib txawv. Qhov no qhia tau hais tias pretreatment los ntawm biofilter hloov cov kab mob hauv zej zog muaj pes tsawg leeg ntawm biofouling txheej thiab ua rau cov qauv hauv zej zog ntau dua. Cov kab mob hauv zej zog muaj pes tsawg leeg ntawm phylum theem hauv biofilter thiab membrane nto fouling txheej tsuas yog muaj Proteobacteria, Actinobacteria, Bacteroidetes, Cyanobacteria, Chloroflexi, Verrucomicrobia, Planctomycetes, thiab Firmicutes.
Piv nrog rau cov dej nyoos hauv zej zog, qhov kev faib ua feem ntawm Proteobacteria, Actinobacteria, Chloroflexi, Firmicutes, thiab Bacteroidetes hauv biofilter microbial zej zog tau nce, thaum qhov kev faib ua feem ntawm Actinobacteria thiab Cyanobacteria txo qis. Firmicutes yog cov kab mob uas muaj nyob hauv cov dej khib nyiab, thiab Actinobacteria yog cov kab mob uas muaj ntau tshaj plaws hauv cov dej tshiab. Yog li ntawd, biofilter khaws cia thiab adsorption ntawm cov organic teeb meem hauv cov dej nyoos muab qhov chaw zoo dua rau Firmicutes, thaum tib lub sijhawm inhibiting kev loj hlob thiab kev loj hlob ntawm Actinobacteria. Proteobacteria koom nrog hauv hydrolysis thiab degradation ntawm cov proteins uas muaj ntxhiab, thiab lawv nce los ntawm qhov thib ob feem ntau phylum mus rau ntau tshaj qhia tau hais tias muaj peev xwm biodegradation nyob rau hauv biofilter. Acidobacteria cuam tshuam nrog kev txo qis ntawm polysaccharides, proteins, thiab lipids, thaum Bacteroidetes thiab Chlorophyta kuj koom nrog kev tshem tawm cov organic teeb meem. Cov kab mob no sib sau ua ke ua rau kev puas tsuaj ntawm cov organic teeb meem hauv dej thiab txo cov kab mob ceramic tom qab fouling. Muab piv rau cov zej zog lom neeg muaj pes tsawg leeg ntawm lub txaj lim, qhov kev faib ua feem ntawm Proteobacteria, Actinobacteria, Cyanobacteria, thiab Firmicutes nyob rau hauv cov fouling txheej ntawm daim nyias nyias yog nce, thaum qhov kev faib ua feem ntawm Acidobacteria thiab Chlorophyta yog txo. Qhov sib txawv no feem ntau yog vim cov txheej txheem ceramic membrane yog ib theem tom ntej hauv biofilter, thiab cov fouling txheej tau ntxuav tas li, ua rau muaj qhov sib txawv ntawm cov kab mob hauv zej zog ntawm ob.
