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 endle yemishini yokwelapha indle yasekhaya yasemakhaya, amabhaktheriya aqoqa i-phosphorus agcina amandla kuma-compound aqoqa i-phosphorus futhi akhiphe ama-phosphate radicals 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, akhiphe i-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 samaphrojekthi okuhlanza indle yasekhaya asemakhaya, ukukhethwa kwenqubo yokuhlanza indle kufanele kuhlangabezane nezidingo zesilinganiso sokuhlanza, izici zendle, ikhwalithi yamanzi angcolile kanye nomzimba wamanzi akhishwayo. Ngesikhathi esifanayo, inqubo yokuhlanza efanele kufanele ikhethwe ngokwezimpawu zendle yasendaweni. Amacala amaningi abonisa ukuthi imishini yokuhlanza indle yasemaphandleni ye-AAO iyakwazi ukuzivumelanisa kahle nezinhlobo ezahlukene zamaphrojekthi.
