Ho latela lintlha tsa morao-rao tsa thekiso, palo ea litaelo tse amoheloang ke Liding Environmental Protection bakeng sa lisebelisoa tsa ts'ebetso ea AAO e ntse e le holimo. Ke lintlha life tse etsang hore bareki ba tšepe ts'ebetso ee haholoanyane? Ka mor'a moo, Tšireletso ea Tikoloho ea Liding e tla hlahisa moelelo oa ts'ebetso ea AAO.
Moko 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 bokellang phosphorus ho tlosa phosphorus. Ka hona, ts'ebetso ena e loketse haholoanyane merero e nang le taolo e tiileng ea litšila tsa naetrojene le phosphorus. Mesebetsi e ka sehloohong ea lisebelisoa tsa tsamaiso ea likhoerekhoere tsa mahaeng tsa AAO li tsepamisitsoe mefuteng e meraro ea karabelo, e leng letamo la anaerobic, letamo la anoxic le letamo la aerobic.
Sebakeng sa anaerobic karabelo, ka lebaka la khaello ea nitrate le oksijene ka likhoerekhoere tsa mahaeng thepa ea likhoerekhoere malapeng, phosphorus bokella libaktheria boloka matla ka metsoako phosphorus-pokella le ho lokolla radicals phosphate ka nako e tšoanang, ha libaktheria tse ling ha e le hantle ha e sebetse. Mojuleng ona oa karabelo Libaktheria tse ling ha li sebetse haholo ebile ho thata ho hola. The anaerobic reaction module e sebelisoa ho fokotsa COD le ho lokisetsa ho tlosoa ha phosphorus.
Mojuleng oa anoxic reaction, likhoerekhoere tsa lisebelisoa tsa kalafo tsa likhoerekhoere tsa mahaeng li na le palo e itseng ea nitrate ntle le oksijene, 'me libaktheria tse denitrifying li sebelisa COD ho fokotsa nitrate ho naetrojene, ho lokolla alkali, le ho fumana matla bakeng sa kholo. Fokotsa COD le naetrojene ea nitrate.
Mojule oa aerobic reaction ke sebaka sa mantlha sa karabelo ea lisebelisoa tsa likhoerekhoere malapeng a mahaeng. Mona, libaktheria tsa nitrifying oxidize ammonia nitrogen ho naetrojene ea nitrate, li ja alkalinity le oksijene, li-PAO li monya phosphorus e ngata, li sebelisa matla a PHAs ho kopanya polyphosphorus, 'me li-OHO li tsoela pele ho tlosa COD, PAOs, OHOs le libaktheria tsa nitrifying kaofela li hōlileng ka mokhoa ona. Fokotsa COD, ammonia nitrogen le phosphorus.
Ho tsoa tlhahlobong ea tlhokahalo ea merero ea ho hloekisa likhoerekhoere malapeng, khetho ea ts'ebetso ea likhoerekhoere e lokela ho fihlela litlhoko tsa sekala sa kalafo, litšoaneleho tsa likhoerekhoere, boleng ba metsi a litšila le 'mele oa metsi a litšila. Ka nako e ts'oanang, mokhoa o nepahetseng oa phekolo o lokela ho khethoa ho ea ka litšobotsi tsa likhoerekhoere tsa sebaka seo. Maemo a mangata a bonts'a hore lisebelisoa tsa ho hloekisa likhoerekhoere tsa mahaeng tsa AAO li na le maemo a matle a ho ikamahanya le mefuta e fapaneng ea merero.
