Ukugweba kwidatha yokuthengisa yamva nje, inani lee-odolo ezifunyenwe ngokukhuselekileyo kwendawo yokusingqongileyo kwizixhobo ze-AAO Inkqubo iphakame. Zeziphi izinto ezenza ukuba abathengi bayayithemba le nkqubo ngakumbi? Ukukhuselwa kokusingqongileyo okulandelayo, ukulungisa imeko kuya kwazisa isiseko senkqubo yea-AAO.
Eyona nto iphambili kwinkqubo yea-AAO kukusebenzisa ubuchule kunye nokuguqula izinto eziphilayo phantsi kweemeko ezahlukeneyo ukufezekisa ukususwa kwe-nitrogen, kunye nokusebenzisa intsholongwane ye-phosphorus. Ke ngoko, le nkqubo ifanelekile ngakumbi kwiiprojekthi ezinolawulo olungqongqo lwe-nitrogen kunye nokungcoliseka kwe phosphorus. Ezona misebenzi ziphambili kwizixhobo zonyango lwasekhaya ze-AAO zenkqubo ye-AAO zigxile kwiimodyuli ezintathu zokuphendula, eziyiphuli ye-anaerobic, ichibi elinamachizi kunye nephuli ye-aerobic.
Kwindawo yokuphendula ye-Anaerobic, ngenxa yokunqongophala kwe-nitrate kunye neoksijini kwi-Subage yezixhobo zokunyanga zasekhaya zasekhaya kwi-Phosteria kwi-phosphorus-radicals ngaxeshanye, ngelixa ezinye iintsholongwane azisebenzi. Kule modyuli yokuphendula ezinye iintsholongwane azikho kangako kwaye kunzima ukukhula. Imodyuli yokuphendula ye-Anaerobic isetyenziselwa ukunciphisa i-CoD kwaye ilungiselele ukususwa kwephospirus.
Kwimodyuli yokuphendula enetyhefu, ukuntywila kwezixhobo zonyango lwasekhaya zinexabiso elithile le-niterate ngaphandle kweoksijini, kunye nokuphelisa i-bacteria ukuba isebenzise i-nitragen, ikhuphe iAlkali, kwaye ifumane amandla okukhula. Ukunciphisa i-CoD kunye ne-nitrogen nitrogen.
Imodyuli yokuphendula ye-Aerobic yindawo engundoqo lwendawo engundoqo lwezixhobo zonyango lwasekhaya. Apha, ukothusa i-bacteria axize i-Ammonia nitrogen ukuya kwi-nitrogen, sebenzisa i-Alkalinity, i-oxygen, i-PARS, i-OHOS, kunye ne-Ohos, kunye ne-Bitteria yonke i-bacteria yonke ikhule kule nkqubo. Ukunciphisa i-CoD, i-Amonia nitrogen kunye nePhosphorus.
Ukusuka kuhlalutyo lwebango lweeprojekthi zonyango lwasemaphandleni, ukhetho lwenkqubo yokunyanga amanzi amdaka kufuneka uhlangabezane neemfuno zonyango, iimpawu zotywala, umgangatho wamanzi amdaka, kunye nomzimba wamanzi amdaka. Kwangelo xesha, inkqubo efanelekileyo yonyango kufuneka ikhethwe ngokweempawu zotywala zalapha ekhaya. Amatyala amaninzi abonisa ukuba izixhobo zokunyanga ze-Aao Lage Gebage zinezikhundla ezifanelekileyo kwiindidi ezahlukeneyo zeeprojekthi.
