Iyo yemuviri uye diki chimiro che volcanic rock biofilter material inoratidzwa nehutsinye hwepamusoro uye micropore, iyo inonyanya kukodzera kukura uye kuberekana kwema microorganisms pamusoro payo kugadzira biofilm.Volcanic rock filter material haingorapise mvura yakasviba yemanisipala, asiwo biochemical organic industry wastewater, drainage yemumba, micro polluted source water, etc. inogonawo kutsiva jecha requartz, activated carbon, anthracite sefirita midhiya mukurapwa kwemvura.Panguva imwecheteyo, inogonawo kuita kurapa kwepamusoro kwemvura yemuswe mushure mechikamu chechipiri chekurapa kwechigadzirwa chekuchenesa tsvina, uye mvura yakagadziriswa inogona kusvika pamvura inoshandiswa zvakare inogona kushandiswa pakugadzirisa zvakare kushandiswa kwemvura.

Iyo kemikari microstructure ye volcanic rock biofilter zvinhu zvinotevera

1. Kugadzikana kwemakemikari eMicrobial: volcanic rock biofilter material inodzivirira corrosion, inert, uye haipindi mukuita kwebiochemical reaction yebiofilm munharaunda.

2. Surface magetsi uye hydrophilicity: pamusoro pe volcanic rock biofilter ine mutero wakanaka, unobatsira pakukura kwe microorganisms.Iyo ine yakasimba hydrophilicity, yakakura yakawanda yakasungirirwa biofilm uye nekukurumidza kumhanya.

3. Semutakuri webiofilm, volcanic rock biofilter haina kukuvadza uye inhibitive effect pane immobilized microorganism, uye yakaratidza kuti haikanganisi basa re microorganism.

Iyo hydraulic performance ye volcanic rock biofilter ndeiyi inotevera

1. Porosity: avhareji porosity mukati nekunze inenge 40%, uye kushorwa kwemvura kuduku.Panguva imwecheteyo, kana ichienzaniswa nemhando imwechete yefirita midhiya, huwandu hwesefa midhiya inodiwa ishoma, iyo inogona zvakare kuzadzikisa inotarisirwa kusefa.

2. Nzvimbo chaiyo yenzvimbo: nzvimbo huru yakananga, yakakwirira porosity uye inert, iyo inobatsira pakubata nekukura kwehutachiona, kuchengetedza humwe hutachiona hwehutachiona, uye kufambisa nzira yekufambisa yakawanda yeokisijeni, kudya uye tsvina inogadzirwa mukugadzirwa kwe microbial. metabolism.

3. Sefa zvinhu chimiro uye nzira yekuyerera kwemvura: nekuti iyo volcanic rock biological sefa zvinhu haina kunongedza granular, uye yakawanda yepore dhayamita yakakura kupfuura ceramsite, ine kushoma kupikisa kuyerera kwemvura uye inochengetedza kushandiswa kwesimba.
