Cov qauv ntawm cov pob zeb volcanic biofilter yog lub cev thiab cov qauv me me uas muaj cov qhov ntxhib thiab cov qhov me me, uas yog qhov tshwj xeeb tshaj yog rau kev loj hlob thiab kev tsim cov kab mob me me ntawm nws qhov chaw los tsim cov biofilm. Cov khoom siv lim pob zeb volcanic tsis yog tsuas yog kho cov dej khib nyiab hauv nroog xwb, tab sis kuj tseem kho cov dej khib nyiab organic industrial, cov dej ntws hauv tsev, cov dej qias neeg me me, thiab lwm yam. Nws kuj tseem tuaj yeem hloov cov xuab zeb quartz, cov pa roj carbon activated, anthracite ua cov lim dej hauv kev kho dej. Tib lub sijhawm, nws kuj tuaj yeem ua kev kho dej siab rau cov dej tom qab cov txheej txheem kho thib ob ntawm cov chaw kho dej phwj tuaj yeem ua tiav cov dej rov siv dua. Nws tuaj yeem siv rau kev siv dej rov qab.

Cov qauv tshuaj lom neeg ntawm cov pob zeb volcanic biofilter khoom siv yog raws li nram no

1. Kev ruaj khov ntawm cov kab mob me me: cov khoom siv biofilter pob zeb volcanic yog cov khoom siv tiv taus xeb, tsis muaj zog, thiab tsis koom nrog cov tshuaj tiv thaiv biofilm hauv ib puag ncig.

2. Hluav taws xob ntawm qhov chaw thiab hydrophilicity: qhov chaw ntawm cov pob zeb volcanic biofilter muaj qhov them zoo, uas yog qhov zoo rau kev loj hlob ntawm cov kab mob me me. Nws muaj hydrophilicity muaj zog, ntau cov biofilm txuas nrog thiab ceev ceev.

3. Ua tus nqa khoom ntawm biofilm, volcanic pob zeb biofilter tsis muaj kev phom sij thiab kev cuam tshuam rau cov kab mob immobilized, thiab nws tau ua pov thawj tias nws tsis cuam tshuam rau kev ua haujlwm ntawm cov kab mob.

Cov kev ua haujlwm hydraulic ntawm volcanic pob zeb biofilter yog raws li nram no

1. Qhov porosity: qhov nruab nrab porosity sab hauv thiab sab nraud yog li 40%, thiab qhov tsis kam rau dej yog me me. Tib lub sijhawm, piv nrog tib hom lim dej, qhov ntau ntawm cov lim dej xav tau tsawg dua, uas kuj tuaj yeem ua tiav lub hom phiaj lim dej xav tau.

2. Thaj chaw tshwj xeeb: thaj chaw loj tshwj xeeb, porosity siab thiab inert, uas yog qhov zoo rau kev sib cuag thiab kev loj hlob ntawm cov kab mob me me, tswj cov kab mob biomass ntau dua, thiab pab txhawb cov txheej txheem hloov pauv ntawm cov pa oxygen, cov as-ham thiab cov khib nyiab tsim nyob rau hauv cov txheej txheem ntawm cov kab mob metabolism.

3. Cov duab ntawm cov khoom siv lim dej thiab cov qauv dej ntws: vim tias cov khoom siv lim dej ntawm cov pob zeb volcanic tsis yog cov pob zeb me me, thiab feem ntau ntawm cov qhov loj dua li ceramsite, nws muaj kev tiv thaiv me me rau cov dej ntws thiab txuag kev siv hluav taws xob.
