Maonekedwe akuthupi ndi ang'onoang'ono a miyala ya volcanic rock biofilter imadziwika ndi mawonekedwe owoneka bwino komanso ma micropore, omwe ndi oyenera makamaka kukula ndi kubereka kwa tizilombo tating'onoting'ono kuti tipange biofilm.Zosefera za volcanic thanthwe sizingathetse madzi onyansa a tapala, komanso madzi am'madzi am'mafakitale achilengedwe, ngalande zam'nyumba, madzi owonongeka ang'onoang'ono, ndi zina zambiri. zimathanso kulowa m'malo mwa mchenga wa quartz, activated carbon, anthracite ngati media media popereka madzi.Panthawi imodzimodziyo, imatha kuchitanso chithandizo chapamwamba chamadzi amchira pambuyo pa njira yachiwiri yochizira zonyansa, ndipo madzi oyeretsedwa amatha kufika pamadzi ogwiritsira ntchito madzi Angagwiritsidwe ntchito pobwezeretsanso madzi.

The chemical microstructure of volcanic rock biofilter material ndi motere

1. Kukhazikika kwamankhwala ang'onoang'ono: volcanic rock biofilter material ndi yosawononga dzimbiri, inert, ndipo satenga nawo mbali pazochitika za biochemical za biofilm m'chilengedwe.

2. Magetsi apamtunda ndi hydrophilicity: pamwamba pa miyala ya volcanic biofilter imakhala ndi mtengo wabwino, womwe umathandizira kukula kwa tizilombo toyambitsa matenda.Ili ndi hydrophilicity yamphamvu, kuchuluka kwa biofilm yolumikizidwa komanso kuthamanga kwachangu.

3. Monga chonyamulira cha biofilm, chiphala thanthwe biofilter alibe zoipa ndi inhibitive zotsatira pa immobilized tizilombo tating'onoting'ono, ndipo zatsimikiziridwa kuti sizimakhudza ntchito ya tizilombo.

Ma hydraulic performance ya volcanic rock biofilter ndi motere

1. Porosity: pafupifupi porosity mkati ndi kunja ndi pafupifupi 40%, ndipo kukana madzi ndi kochepa.Nthawi yomweyo, poyerekeza ndi mtundu womwewo wa zosefera, kuchuluka kwa zosefera zomwe zimafunikira ndizochepa, zomwe zimathanso kukwaniritsa cholinga chosefa chomwe chikuyembekezeka.

2. Malo enieni: malo akuluakulu apamwamba, porosity yapamwamba ndi inert, yomwe imathandizira kukhudzana ndi kukula kwa tizilombo toyambitsa matenda, kusunga tizilombo toyambitsa matenda, ndikuthandizira kupititsa patsogolo kwa oxygen, zakudya ndi zinyalala zomwe zimapangidwira panthawi ya tizilombo toyambitsa matenda. metabolism.

3. Mawonekedwe a zinthu zosefera ndi kayendedwe ka madzi: chifukwa volcanic rock biological filter material ndi yopanda nsonga, ndipo ma pore awiri ake ndi aakulu kuposa ceramsite, imakhala ndi mphamvu zochepa zotsutsana ndi madzi ndikupulumutsa mphamvu.
