Dombo rinoputika (rinowanzozivikanwa sepumice kana porous basalt) chinhu chinoshanda uye chinoenderana nemamiriro ekunze, inova ibwe rinokosha kwazvo rinoumbwa negirazi rinoputika, zvicherwa, uye mabhubhu mushure mekuputika kwegomo.Dombo rinoputika rine akawanda emaminerari uye kutsvaga zvinhu zvakaita sesodium, magnesium, aluminium, silicon, calcium, titanium, manganese, iron, nickel, cobalt, uye molybdenum.Haisi kupenya uye ine kure-infrared magnetic waves.Mushure mekuputika kwegomo kusina tsitsi, mushure memakumi ezviuru zvemakore, Vanhu vari kuwedzera kuwana kukosha kwaro.Ikozvino yawedzera minda yayo yekushandisa kuminda yakaita sekuvaka, kuchengetedza mvura, kukuya, mafirita, marasha ebarbecue, kugadzirwa kwevhu, kurima kusina ivhu, uye zvigadzirwa zvekushongedza, zvichiita basa risingadzokerike mumaindasitiri akasiyana.

Hunhu hwe volcanic pumice (basalt) uye chimiro che volcanic rock biological filter materials.
Chitarisiko uye chimiro: Hapana zvidimbu zvakapinza, kushomeka kwekudzivirira kuyerera kwemvura, hazvisi nyore kuvhara, mvura yakagovaniswa nemhepo, nzvimbo yakaoma, inokurumidza kurembera firimu, uye isinganyanyi kutarisana ne microbial film detachment panguva yekudzokororwa.

Porosity: Matombo anoputika ane masero uye ane porous, zvichiita kuti ive nzvimbo yakanakisisa yekukura kune nharaunda dzehutachiona.
Mechanical simba: Zvinoenderana nedhipatimendi renyika rekuongorora mhando, iri 5.08Mpa, iyo yakaratidza kutsungirira hydraulic shear mhedzisiro yesimba rakasiyana uye ine hupenyu hwesevhisi hwakareba kupfuura mamwe mafirita.
Density: Yakadzikama density, iri nyore kumisa panguva yekugezesa kumashure pasina kubuda kwezvinhu, izvo zvinogona kuchengetedza simba uye kuderedza kushandiswa.

Kugadzikana kwebiochemical: Volcanic rock biofilter zvinhu zvinodzivirira corrosion, inert, uye hazvitore chikamu mukuita kwebiochemical yemabiofilms munzvimbo.
Magetsi epamusoro uye hydrophilicity: Iyo yekumusoro kwedombo regomo biofilter ine chaji yakanaka, iyo inobatsira mukukura kwakamira kwehutachiona.Iyo ine yakasimba hydrophilicity, yakakura yakawanda yakasungirirwa biofilm, uye nekukurumidza kumhanya.

Panyaya yekukanganisa pane biofilm chiitiko: Semutakuri webiofilm, volcanic rock biofilter media haina kukuvadza uye haina inhibitory mhedzisiro pane yakagadziriswa tupukanana, uye maitiro aratidza kuti haikanganise basa rehutachiona.
Hydraulics maitiro e volcanic rock biological sefa zvinhu.

Void rate: Avhareji yeporosity mukati nekunze yakatenderedza 40%, iyo ine kushomeka kwekudzivirira kumvura.Panguva imwecheteyo, kana ichienzaniswa neyakafanana sefa zvinhu, iyo inodiwa huwandu hwesefa zvinhu ishoma, uye inotarisirwa kusefa chinangwa chinogonawo kuwanikwa.
Yakananga nzvimbo yepasi: Iine hombe yakananga nzvimbo, yakakwirira porosity, uye inertness, inobatsira pakubata uye kukura kwehutachiona, kuchengetedza yakakwira microbial biomass, uye kufambisa nzira yekufambisa yakawanda yeokisijeni, zvinovaka muviri, uye tsvina inogadzirwa panguva yehutachiona. metabolism.
Sefa zvinhu chimiro uye nzira yekuyerera kwemvura: Nekuda kwekuti volcanic rock biological sefa zvinhu hazvina kunongedza zvimedu uye zvine hombe pore saizi kupfuura zvimedu zveceramic, ivo vane kushomeka kwekuramba kuyerera kwemvura uye kuchengetedza kushandiswa kwesimba kana kuchishandiswa.

Hunhu hwayo ndehwekuti ine ma pores akawanda, huremu huremu, simba rakakwirira, kuvharisa, kupfekwa kwenzwi, kudzivirira moto, acid uye alkali resistance, corrosion resistance, uye haina kusvibiswa uye isina radioactive.Iyo yakanaka yakasikwa yegirini, ine hushamwari kwezvakatipoteredza uye inochengetedza simba rew material.
