1. Khethollo ea theknoloji ea phekolo ea likhoerekhoere tsa likokoana-hloko le melemo le mathata a eona: Mokhoa oa phekolo ea likokoana-hloko oa likhoerekhoere o atisa ho aroloa ka mokhoa oa sludge o kentsoeng bakeng sa kholo ea ho emisa le mokhoa oa biofilm bakeng sa kholo ea ho khomarela. Melemo ea mokhoa oa sludge o kentsoeng ke hore ts'ebetso e butsoitse, mekhoa ea ts'ebetso e bonolo ho e lokisa, 'me boleng ba mokelikeli bo botle,' me boholo ba lisebelisoa tsa likhoerekhoere li sebelisa mokhoa oa seretse o kentsoeng, mme mathata ke hore boholo ba karabelo. sebopeho se batla se le seholo, seretse se setseng se feta, 'me seretse se bonolo ho ruruha.
Melemo ea mokhoa oa biofilm ke ho hanyetsa ka matla ho ts'oarelo ea mojaro, molumo oa sekontiri o nyane, ho atolosoa ha seretse ho ke ke ha etsahala, 'me seretse se setseng se fokotsehile,' me bobe ke hore boleng ba metsi a litšila bo fokola hanyane, haholoholo ha metsi a le teng. boleng le bongata li fetoha haholo, biofilm e khaoloa haholo, 'me boleng ba metsi bo fetoha haholo.
2. Traditional A/O kapa A2/O biological denitrification theory: the ammonia naetrojene ka likhoerekhoere tsa malapeng e fetoloa nitrate le nitrite ka libaktheria autotrophic nitrifying le oksijene e le elektrone amohelang nakong ea tshebetso nitrification, ebe nitrate le nitrite fokotswa khase. ka libaktheria tsa heterotrophic denitrifying ho hlakisa likhoerekhoere. Hobane libaktheria tsa nitrifying li na le matla a matla a aerobic, ts'ebetso ea nitrification e tlameha ho ba ea aerobic, ha libaktheria tsa setso tse hlalosang oksijene li sebelisa oksijene joalo ka moamoheli oa elektrone ho etsa phefumoloho ea aerobic tlas'a maemo a aerobic, 'me ke feela sebakeng sa anaerobic moo ba sebelisang nitrate kapa nitrite joalo ka moamoheli oa elektrone. ho fumana matla a ho kopanya 'mele oa sele, kahoo libaktheria tsa setso tse hlalosang li ka etsa feela denitrification sebakeng sa anoxic. Ts'ebetso ea setso ea biological denitrification e ntlafalitsoeng ho ea ka khopolo e kaholimo e arola tanka ea anaerobic (facultative) ho tanka ea aerobic, e lebisang mefokolong ea ts'ebetso joalo ka phallo e telele ea ts'ebetso, matsete a phahameng a meaho, ts'ebetso e rarahaneng ea sistimi le ts'ebetso, le tlhoko ea ho tlatselletsa khabone. mehloli ea tanka ea denitrification.
