Uma sibheka idatha yokuthengisa yakamuva, inani lama-oda atholwe yi-Liding Environmental Protection yemishini yenqubo ye-AAO lisephezulu. Yiziphi izici ezenza amakhasimende athembele kakhulu kule nqubo? Okulandelayo, i-Liding Environmental Protection izokwethula umongo wenqubo ye-AAO.
Ingqikithi yenqubo ye-AAO ukusebenzisa i-nitrification kanye ne-denitrification yezinto eziphilayo ngaphansi kwezimo ezahlukene ukuze kufezwe ukususwa kwe-nitrogen, kanye nokusebenzisa amabhaktheriya aqoqa i-phosphorus ukususa i-phosphorus. Ngakho-ke, le nqubo ifaneleka kakhulu kumaphrojekthi anokulawula okuqinile ukungcola kwe-nitrogen ne-phosphorus. Imisebenzi eyinhloko yemishini yokwelapha indle yasekhaya yasemakhaya yenqubo ye-AAO igxile kumamojula amathathu okusabela, okuyichibi elingena-aerobic, ichibi elingena-oxic kanye nechibi le-aerobic.
Endaweni yokusabela kwe-anaerobic, ngenxa yokuntuleka kwe-nitrate kanye nomoya-mpilo endleimishini yokuhlanza indle yasekhaya yasemakhaya, amabhaktheriya aqoqa i-phosphorus agcina amandla kuma-compound aqoqa i-phosphorus futhi akhulule ama-radical e-phosphate ngesikhathi esifanayo, kuyilapho amanye amabhaktheriya engasebenzi. Kule module yokusabela Amanye amabhaktheriya awasebenzi kakhulu futhi kunzima ukuwakhulisa. Imoduli yokusabela kwe-anaerobic isetshenziselwa ukunciphisa i-COD nokulungiselela ukususwa kwe-phosphorus.
Kumojuli yokusabela kwe-anoxic, indle yemishini yokwelapha indle yasekhaya yasemakhaya inenani elithile le-nitrate ngaphandle komoya-mpilo, futhi amabhaktheriya asusa i-nitrit asebenzisa i-COD ukunciphisa i-nitrate ibe yi-nitrogen, akhulule ama-alkali, futhi athole amandla okukhula. Yehlisa i-COD kanye ne-nitrate i-nitrogen.
Imodyuli yokusabela kwe-aerobic iyindawo eyinhloko yokusabela kwemishini yokwelapha indle yasekhaya yasemakhaya. Lapha, amabhaktheriya ane-nitrogen axuba i-nitrogen ye-ammonia ibe yi-nitrate, adle i-alkalinity kanye nomoya-mpilo, ama-PAO amunca inani elikhulu le-phosphorus, asebenzise amandla kuma-PHA ukukhiqiza i-polyphosphorus, kanti ama-OHO ayaqhubeka nokususa ama-COD, ama-PAO, ama-OHO, kanye namabhaktheriya ane-nitrogen akhuliswa kule nqubo. Yehlisa i-COD, i-nitrogen ye-ammonia kanye ne-phosphorus.
Kusukela ekuhlaziyweni kwesidingo sezindawo zasemakhayaukwelashwa kwendle yasekhayaAmaphrojekthi, ukukhethwa kwenqubo yokwelapha indle kufanele kuhlangabezane nezidingo zesikali sokwelapha, izici zendle, ikhwalithi yamanzi angcolile kanye nomzimba wamanzi akhishwayo. Ngesikhathi esifanayo, inqubo yokwelapha efanele kufanele ikhethwe ngokwezici zendle yendawo. Amacala amaningi abonisa ukuthi imishini yokwelapha indle yasemakhaya ye-AAO iyakwazi ukuzivumelanisa kahle nezinhlobo ezahlukene zamaphrojekthi.
