Ulwakhiwo olubonakalayo noluncinci lwezinto ze-biofilter zelitye lentaba-mlilo luphawulwa ngumphezulu orhabaxa kunye ne-micropore, efanelekileyo ngokukodwa ekukhuleni nasekuzaleni kweentsholongwane kumphezulu wazo ukuze zenze i-biofilm. Izinto ze-volcanic rock filter azikwazi nje kuphela ukunyanga amanzi amdaka kamasipala, kodwa zikwanazo namanzi amdaka e-biochemical organic industrial, i-drainage yasekhaya, amanzi omthombo angcolileyo amancinci, njl. zinokuthatha indawo yesanti ye-quartz, i-activated carbon, i-anthracite njenge-filter media kunyango lonikezelo lwamanzi. Kwangaxeshanye, zinokwenza unyango oluphambili lwamanzi asemva emva kwenkqubo yesibini yonyango lwesityalo sonyango lwelindle, kwaye amanzi acociweyo anokufikelela kumgangatho wamanzi okusetyenziswa kwakhona. Angasetyenziselwa ukuphinda asetyenziswe amanzi.

Isakhiwo seekhemikhali sezinto ezihluza iintsholongwane zelitye lentaba-mlilo silandelayo

1. Uzinzo lweekhemikhali ze-microbial: izinto ze-biofilter zelitye lentaba-mlilo azikwazi ukugqwala, azinamsebenzi, kwaye azithathi nxaxheba kwi-biofilm reaction ye-biofilm kwindalo esingqongileyo.

2. Umbane ongaphezulu kunye nokuthambeka kwamanzi: umphezulu we-biofilter yelitye lentaba-mlilo unetshaja entle, enceda ekukhuleni kweentsholongwane. Ine-hydrophilicity enamandla, inani elikhulu le-biofilm eqhotyoshelweyo kunye nesantya esikhawulezayo.

3. Njengomthwali we-biofilm, i-biofilter yamatye entaba-mlilo ayinayo impembelelo enobungozi neyithintelayo kwi-microorganism engakwaziyo ukuhamba, kwaye kuye kwabonakala ukuba ayichaphazeli umsebenzi we-microorganism.

Ukusebenza kwe-hydraulic ye-biofilter yamatye entaba-mlilo kulandelayo

1. Ukuxinana: ukuxinana okuphakathi ngaphakathi nangaphandle kumalunga ne-40%, kwaye ukumelana namanzi kuncinci. Kwangaxeshanye, xa kuthelekiswa nohlobo olufanayo lwe-filter media, ubungakanani be-filter media efunekayo buncinci, nto leyo enokufezekisa injongo yokucoca elindelweyo.

2. Indawo ethile yomphezulu: indawo enkulu yomphezulu othile, ukuvuleka okuphezulu kunye nokungangeni kakuhle, okunceda ukudibana nokukhula kweentsholongwane, ukugcina i-biomass eninzi yeentsholongwane, kunye nokwenza lula inkqubo yokudluliselwa kobuninzi beoksijini, izondlo kunye nenkunkuma eveliswa kwinkqubo yemetabolism yeentsholongwane.

3. Imilo yezinto zokucoca kunye nepatheni yokuhamba kwamanzi: kuba izinto zokucoca zebhayoloji zelitye lentaba-mlilo azinazo iingceba, kwaye uninzi lobubanzi bemingxuma bukhulu kune-ceramsite, ayinakumelana nokuhamba kwamanzi kwaye igcina ukusetyenziswa kwamandla.
