Cov yam ntxwv ntawm volcanic pumice (basalt) thiab lub cev lub cev ntawm volcanic pob zeb biofiltration cov ntaub ntawv.

Cov tsos mob thiab cov duab: Tsis muaj cov khoom ntse, tsis tshua muaj dej ntws, tsis yooj yim los thaiv, sib npaug ntawm cov dej thiab huab cua, ntxhib nto, ceev cov yeeb yaj kiab dai ceev, thiab tsis tshua muaj microbial zaj duab xis detachment thaum rov yaug dua.
Porosity: Pob zeb Volcanic yog cov cellular thiab ntxeem tau, ua rau lawv qhov chaw loj hlob zoo tshaj plaws rau cov zej zog microbial.
Mechanical zog: Raws li lub teb chaws kev soj ntsuam zoo department, nws yog 5.08Mpa, uas tau raug pov thawj los tiv thaiv hydraulic shear los ntawm txawv zog thiab muaj lub neej ntev kev pab cuam ntau tshaj li lwm yam lim ntaub ntawv.
Qhov ceev faj: nrawm nrawm, yooj yim rau ncua thaum tom qab ntxuav tas, uas tuaj yeem txuag lub zog thiab kev noj haus.
Kev ruaj ntseg tshuaj lom neeg: volcanic pob zeb lom neeg lim khoom yog corrosion resistant, inert, thiab tsis koom nrog biochemical cov tshuaj tiv thaiv ntawm biofilm nyob rau hauv ib puag ncig.

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

Hais txog kev cuam tshuam ntawm biofilm kev ua haujlwm: Raws li cov khoom siv biofilm, volcanic pob zeb biofilter media tsis muaj teeb meem thiab tsis muaj qhov cuam tshuam rau cov kab mob ruaj khov, thiab kev xyaum ua pov thawj tias nws tsis cuam tshuam rau kev ua ntawm cov kab mob.
Hydraulic yam ntxwv ntawm volcanic pob zeb biological lim khoom.

Tsis muaj nqi: Qhov nruab nrab porosity sab hauv thiab sab nraud yog nyob ib ncig ntawm 40%, uas muaj qhov tsis kam tiv thaiv dej.Nyob rau tib lub sijhawm, piv rau cov ntaub ntawv lim zoo sib xws, qhov xav tau ntawm cov khoom lim dej tsawg dua, thiab lub hom phiaj kev lim dej yuav tsum tau ua tiav.
Cov cheeb tsam tshwj xeeb: Nrog rau thaj chaw loj tshwj xeeb, qhov porosity siab, thiab inertness, nws yog qhov tsim nyog rau kev sib cuag thiab kev loj hlob ntawm cov kab mob, tswj cov kab mob microbial siab, thiab ua kom yooj yim rau kev hloov pauv huab cua ntawm cov pa oxygen, cov as-ham, thiab pov tseg tsim tawm thaum lub sij hawm microbial. metabolism.

Cov khoom lim dej thiab cov qauv dej ntws: Vim qhov tseeb tias volcanic pob zeb lom cov khoom siv lim dej tsis yog cov ntsiab lus taw qhia thiab muaj qhov pore loj dua li cov khoom siv ceramic, lawv muaj qhov tsis zoo rau cov dej ntws thiab txuag hluav taws xob thaum siv.
Nws cov yam ntxwv yog tias nws muaj ntau qhov pores, lub teeb yuag, siab zog, rwb thaiv tsev, suab nqus, tiv thaiv hluav taws, acid thiab alkali tsis kam, corrosion kuj, thiab tsis muaj kuab paug thiab tsis muaj hluav taws xob.Nws yog ib qho zoo tagnrho ntuj ntsuab, ib puag ncig tus phooj ywg thiab txuag hluav taws xob raw khoom.
