Lub cev thiab micro qauv ntawm volcanic pob zeb biofilter cov khoom yog tus cwj pwm los ntawm ntxhib nto thiab micropore, uas yog tshwj xeeb tshaj yog haum rau kev loj hlob thiab kev loj hlob ntawm cov kab mob nyob rau hauv nws nto los tsim biofilm.Volcanic pob zeb lim cov khoom siv tsis tau tsuas yog kho cov dej khib nyiab hauv nroog, tab sis kuj biochemical organic muaj cov dej khib nyiab, cov dej hauv tsev, cov dej tsis huv micro, thiab lwm yam. nws tuaj yeem hloov quartz xuab zeb, activated carbon, anthracite li lim media hauv dej kho.Nyob rau tib lub sijhawm, nws tseem tuaj yeem ua qhov kev kho mob siab tshaj plaws rau tus Tsov tus tw dej tom qab cov txheej txheem thib ob ntawm kev kho cov dej phwj tuaj, thiab cov dej kho tau tuaj yeem ncav cuag tus qauv dej rov siv dua Nws tuaj yeem siv rau cov dej rov qab siv dua.

Cov tshuaj microstructure ntawm volcanic pob zeb biofilter khoom yog raws li nram no

1. Microbial tshuaj stability: volcanic pob zeb biofilter cov khoom yog corrosion-resistant, inert, thiab tsis koom nyob rau hauv biochemical cov tshuaj tiv thaiv ntawm biofilm nyob rau hauv ib puag ncig.

2. Nto hluav taws xob thiab hydrophilicity: nto ntawm volcanic pob zeb biofilter muaj cov nqi zoo, uas yog qhov tsim nyog rau kev loj hlob ntawm cov kab mob.Nws muaj zog hydrophilicity, ib tug loj npaum li cas ntawm biofilm txuas thiab ceev ceev.

3. Raws li cov cab kuj ntawm biofilm, volcanic pob zeb biofilter tsis muaj teeb meem thiab inhibitive nyhuv ntawm cov kab mob immobilized, thiab nws tau raug pov thawj tias nws tsis cuam tshuam rau kev ua ntawm cov kab mob.

Kev ua haujlwm hydraulic ntawm volcanic pob zeb biofilter yog raws li hauv qab no

1. Porosity: qhov nruab nrab porosity sab hauv thiab sab nraud yog li 40%, thiab cov dej tsis kam yog me me.Nyob rau tib lub sijhawm, piv nrog tib hom lim xov xwm, tus nqi ntawm cov xov xwm lim dej xav tau tsawg dua, uas tseem tuaj yeem ua tiav lub hom phiaj kev lim dej.

2. Cov cheeb tsam tshwj xeeb: thaj chaw loj tshwj xeeb, siab porosity thiab inert, uas yog qhov tsim nyog rau kev sib cuag thiab kev loj hlob ntawm cov kab mob, tswj cov kab mob microbial ntau dua, thiab pab txhawb kev hloov pauv huab cua ntawm cov pa oxygen, cov as-ham thiab cov khoom pov tseg hauv cov txheej txheem microbial. metabolism.

3. Cov khoom siv lim dej thiab cov qauv dej ntws: vim tias cov khoom siv lim dej volcanic biological lim tsis yog taw qhia granular, thiab feem ntau ntawm cov pore txoj kab uas hla yog loj dua ceramsite, nws muaj me me tsis kam rau cov dej ntws thiab txuag lub zog noj.
