Isakhiwo esibonakalayo nesincane sezinto ze-biofilter zedwala lentaba-mlilo sibonakala ngobuso obumahhadlahhadla kanye ne-micropore, efaneleka kakhulu ekukhuleni nasekuzaleni kwama-microorganisms ebusweni bawo ukuze kwakheke i-biofilm. Izinto zokuhlunga idwala lentaba-mlilo azikwazi nje kuphela ukwelapha amanzi angcolile kamasipala, kodwa futhi namanzi angcolile ezimbonini aphilayo, amanzi ageleza ekhaya, amanzi omthombo angcolile amancane, njll. zingaphinde zithathe indawo yesihlabathi se-quartz, i-activated carbon, i-anthracite njengezinto zokuhlunga ekwelapheni ukuhlinzekwa kwamanzi. Ngesikhathi esifanayo, zingenza futhi ukwelashwa okuthuthukisiwe kwamanzi angemuva ngemva kwenqubo yokwelapha yesibili yesitshalo sokwelapha indle, futhi amanzi aphathwe angafinyelela izinga lamanzi okusetshenziswa kabusha. Angasetshenziswa ekusetshenzisweni kabusha kwamanzi.

Isakhiwo samakhemikhali sezinto zokuhlunga i-biofilter zamadwala entaba-mlilo sinjena

1. Ukuqina kwamakhemikhali amagciwane: izinto zokuhlunga i-biofiltration zamadwala entaba-mlilo azikwazi ukugqwala, azisebenzi, futhi azihlanganyeli ekusabeleni kwamakhemikhali e-biofilm emvelweni.

2. Ugesi ongaphezulu kanye nokuthambekela kwamanzi: ubuso be-biofilter yedwala lentaba-mlilo buneshaja enhle, ekhuthaza ukukhula kwama-microorganisms. Buthambekele emanzini kakhulu, inani elikhulu le-biofilm enamathiselwe kanye nesivinini esisheshayo.

3. Njengomthwali we-biofilm, i-biofilter yamadwala entaba-mlilo ayinawo umphumela olimazayo novimbelayo ku-microorganism engakwazi ukuhamba, futhi kuye kwafakazelwa ukuthi ayithinti umsebenzi we-microorganism.

Ukusebenza kwe-hydraulic kwe-biofilter yamadwala entaba-mlilo kungokulandelayo

1. Ukugoba: isilinganiso sokugoba ngaphakathi nangaphandle singama-40%, kanti ukumelana namanzi kuncane. Ngesikhathi esifanayo, uma kuqhathaniswa nohlobo olufanayo lwemidiya yokuhlunga, inani lemidiya yokuhlunga elidingekayo lincane, okungaphinde kufeze umgomo wokuhlunga olindelekile.

2. Indawo ethile yobuso: indawo enkulu ethile yobuso, ukubhoboka okuphezulu kanye nokungangeni kahle, okusiza ukuthintana nokukhula kwama-microorganism, kugcina i-biomass eningi yama-microorganism, futhi kusiza inqubo yokudlulisa i-oxygen, izakhamzimba kanye nokungcola okukhiqizwa enkambisweni yokusetshenziswa kwama-microorganism.

3. Ukuma kwezinto zokuhlunga kanye nephethini yokugeleza kwamanzi: ngoba izinto zokuhlunga zezinto eziphilayo zedwala lentaba-mlilo azinawo amachashazi acijile, futhi ubukhulu bembobo bukhulu kune-ceramsite, inokumelana okuncane nokugeleza kwamanzi futhi igcina ukusetshenziswa kwamandla.
