Isakhiwo esibonakalayo nesincane se-volcanic rock biofilter material sibonakala ngokumaholoholo kanye ne-micropore, efaneleka kakhulu ukukhula nokukhiqizwa kabusha kwama-microorganisms endaweni yawo ukuze akhe i-biofilm.Izinto zokuhlunga zamatshe entabamlilo azikwazi nje ukwelapha amanzi angcolile kamasipala, kodwa futhi namanzi angcolile e-biochemical organic ezimbonini, i-drainage yasekhaya, amanzi omthombo ongcolile, njll. kungase futhi kuthathele indawo isihlabathi se-quartz, ikhabhoni ecushiwe, i-anthracite njengesisefo sokuhlunga ekuhlanzeni amanzi.Ngesikhathi esifanayo, ingakwazi futhi ukwenza ukwelashwa okuthuthukisiwe kwamanzi omsila ngemva kwenqubo yesibili yokwelashwa kwesitshalo sokuhlanza indle, futhi amanzi ahlanzekile angafinyelela izinga lokuphinda lisetshenziswe Angasetshenziselwa ukuphinda kusetshenziswe amanzi.

I-microstructure yamakhemikhali ye-volcanic rock biofilter material imi kanje

1. Ukuzinza kwamakhemikhali e-Microbial: impahla ye-volcanic ye-biofilter ye-volcanic ayikwazi ukugqwala, ayizinzi, futhi ayihlanganyeli ekuphenduleni kwamakhemikhali e-biofilm endaweni ezungezile.

2. Ugesi ongaphezulu kanye ne-hydrophilicity: indawo engaphezulu ye-volcanic rock biofilter ineshaja enhle, ehambisana nokukhula kwama-microorganisms.Ine-hydrophilicity eqinile, inani elikhulu le-biofilm enamathiselwe kanye nesivinini esisheshayo.

3. Njengomthwali we-biofilm, i-volcanic rock biofilter ayinawo umphumela olimazayo futhi ovimbelayo ku-microorganism engakwazi ukuhamba, futhi kufakazelwe ukuthi ayithinti umsebenzi we-microorganism.

Ukusebenza kwe-hydraulic ye-volcanic rock biofilter imi kanje

1. I-porosity: isilinganiso se-porosity ngaphakathi nangaphandle singama-40%, futhi ukumelana namanzi kuncane.Ngesikhathi esifanayo, uma kuqhathaniswa nohlobo olufanayo lwemidiya yokuhlunga, inani lemidiya yokuhlunga elidingekayo lincane, elingase futhi lifinyelele umgomo wokuhlunga olindelekile.

2. Indawo ethile eqondile: indawo enkulu ethize enkulu, i-porosity ephezulu kanye ne-inert, evumela ukuthintana nokukhula kwama-microorganisms, igcine i-microbial biomass eyengeziwe, futhi yenza kube lula inqubo yokudlulisa umoya-mpilo, imisoco kanye nemfucuza ekhiqizwa inqubo ye-microbial. umzimba.

3. Umumo wempahla yokuhlunga kanye nephethini yokugeleza kwamanzi: ngenxa yokuthi i-volcanic rock biological filter material ayinayo i-granular, futhi iningi lobubanzi bembotshana likhulu kune-ceramsite, linokumelana okuncane nokugeleza kwamanzi futhi yonga ukusetshenziswa kwamandla.
