Ha re sheba lintlha tsa morao tjena tsa thekiso, palo ea liodara tse amohetsoeng ke Liding Environmental Protection bakeng sa lisebelisoa tsa ts'ebetso tsa AAO e ntse e le holimo. Ke lintlha life tse etsang hore bareki ba tšepe ts'ebetso ena haholoanyane? Ka mor'a moo, Liding Environmental Protection e tla hlahisa bohlokoa ba ts'ebetso ea AAO.
Motheo oa ts'ebetso ea AAO ke ho sebelisa nitrification le denitrification ea lintho tse phelang tlas'a maemo a fapaneng ho finyella ho tlosoa ha naetrojene, le ho sebelisa libaktheria tse bokellanang ka phosphorus ho tlosa phosphorus. Ka hona, ts'ebetso ena e loketse haholoanyane mererong e nang le taolo e tiileng ea litšila tsa naetrojene le phosphorus. Mesebetsi e meholo ea lisebelisoa tsa kalafo ea likhoerekhoere tsa mahaeng tsa ts'ebetso ea AAO e tsepamisitsoe ka har'a li-module tse tharo tsa karabelo, e leng letamo la anaerobic, letamo la anoxic le letamo la aerobic.
Sebakeng sa karabelo ea anaerobic, ka lebaka la khaello ea nitrate le oksijene likhoerekhoereng tsalisebelisoa tsa kalafo ea likhoerekhoere tsa mahaeng, libaktheria tse bokellanang tsa phosphorus li boloka matla metsoakong e bokellanang ea phosphorus 'me li lokolla li-radical tsa phosphate ka nako e le' ngoe, ha libaktheria tse ling ha li sebetse. Mojuleng ona oa karabelo Libaktheria tse ling ha li sebetse haholo 'me li thata ho li holisa. Mojuleng oa karabelo ea anaerobic o sebelisetsoa ho fokotsa COD le ho itokisetsa ho tlosoa ha phosphorus.
Mojuleng oa karabelo ea anoxic, likhoerekhoere tsa lisebelisoa tsa kalafo ea likhoerekhoere tsa mahaeng tsa mahaeng li na le nitrate e itseng ntle le oksijene, 'me libaktheria tse nyenyefatsang li sebelisa COD ho fokotsa nitrate ho ba naetrojene, ho lokolla alkali, le ho fumana matla bakeng sa kholo. Fokotsa COD le naetrojene ea nitrate.
Mojule oa karabelo ea aerobic ke sebaka sa mantlha sa karabelo ea lisebelisoa tsa kalafo ea likhoerekhoere tsa mahaeng. Mona, libaktheria tse nang le nitrifying li kopanya ammonia le naetrojene ho nitrate le nitrogen, li ja alkalinity le oksijene, li-PAO li monya phosphorus e ngata, li sebelisa matla a li-PHA ho etsa polyphosphorus, 'me li-OHO li tsoela pele ho tlosa COD, li-PAO, li-OHO, 'me libaktheria tse nang le nitrifying kaofela li lengoa ts'ebetsong ena. Fokotsa COD, ammonia le phosphorus.
Ho tsoa tlhahlobong ea tlhoko ea libaka tsa mahaengkalafo ea likhoerekhoere tsa malapengmererong, khetho ea mokhoa oa ho phekola likhoerekhoere e lokela ho fihlela litlhoko tsa boholo ba kalafo, litšobotsi tsa likhoerekhoere, boleng ba metsi a litšila le 'mele oa metsi a qhalang. Ka nako e ts'oanang, mokhoa o nepahetseng oa kalafo o lokela ho khethoa ho latela litšobotsi tsa likhoerekhoere tsa lehae. Maemong a mangata a bontša hore lisebelisoa tsa kalafo ea likhoerekhoere tsa mahaeng tsa AAO li na le bokhoni bo botle ba ho ikamahanya le mefuta e fapaneng ea merero.
