Qaab dhismeedka jireed iyo kuwa yar yar ee walxaha biofilter dhagaxa volcano waxaa lagu gartaa dusha qallafsan iyo micropore, kaas oo si gaar ah ugu habboon korriinka iyo taranka unugyada yaryar ee dusha sare si ay u sameeyaan biofilm.Walxaha filtarrada dhagaxa Volcanic ma daweyn karaan oo keliya biyaha wasakhda ah ee degmada, laakiin sidoo kale biochemical biyaha wasakhda organic organic, dheecaanka guriga, biyaha wasakhaysan micro, iwm waxa kale oo ay bedeli kartaa ciidda quartz, kaarboon firfircoon, anthracite sida warbaahinta filter ee daaweynta sahayda biyaha.Isla mar ahaantaana, waxay sidoo kale samayn kartaa daaweyn heer sare ah oo loogu talagalay biyaha dabada ka dib habka daaweynta labaad ee daaweynta bulaacada, iyo biyaha la daaweeyay waxay gaari karaan heerka dib u isticmaalka biyaha Waxaa loo isticmaali karaa dib u isticmaalka biyaha dib loo soo celiyay.

Qaab-dhismeedka yar-yar ee kiimikaad ee walxaha biofilter-ka volcano waa sida soo socota

1. Dejinta kiimikada microbial: Volcanic rock biofilter sheyga waa mid u adkaysta daxalka, aan firfircoonayn, kamana qaybqaadato falcelinta biochemical ee biofilm ee deegaanka.

2. Korontada dusha sare iyo biyo-baxa: dusha sare ee dhagaxa dhagaxa ah ee noolaha ayaa leh kharash togan, kaas oo ku haboon korriinka noolaha.Waxay leedahay hydrophilicity xooggan, xaddi badan oo biofilm ah oo ku xiran iyo xawaare degdeg ah.

3. Sida gudbiyaha biofilm-ka, biofilter volcanic rock biofilter ma laha waxyeello iyo wax u dhimi kara noolaha noolaha, waxaana la caddeeyey in aanu saameyn ku yeelanayn dhaqdhaqaaqa noolaha.

Waxqabadka hydraulic ee dhagaxa noolaha ee volcano waa sida soo socota

1. Porosity: celceliska porosity gudaha iyo dibadda waa 40%, caabbinta biyuhuna waa yar tahay.Isla mar ahaantaana, marka la barbar dhigo isla nooca warbaahinta shaandhaynta, xaddiga warbaahinta shaandhada loo baahan yahay waa ka yar tahay, taas oo sidoo kale gaari karta yoolka shaandhaynta ee la filayo.

2. Aagga dusha gaarka ah: aagga dusha sare ee gaarka ah, qulqulka sare iyo qallafsanaanta, kaas oo ku habboon xidhiidhka iyo koritaanka noolaha, ilaalinta noolaha microbial badan, oo fududeeya habka wareejinta ballaaran ee ogsijiinta, nafaqooyinka iyo qashinka laga soo saaro geeddi-socodka microbial dheef-shiid kiimikaad.

3. Shaandhayso qaabka walxaha iyo qaabka socodka biyaha: sababtoo ah dhagaxa dhagaxa volcanada walxaha filtarrada noolaha waa mid aan granular lahayn, iyo inta badan dhexroorka daloolka ayaa ka weyn ceramsite, waxay leedahay iska caabin yar oo socodka biyaha waxayna badbaadisaa isticmaalka tamarta.
