Xa sijonga idatha yentengiso yakutshanje, inani lee-odolo ezifunyenwe yiLiding Environmental Protection yezixhobo zenkqubo ye-AAO lihlala liphezulu. Ziziphi izinto ezenza abathengi bayithembe ngakumbi le nkqubo? Okulandelayo, iLiding Environmental Protection iza kwazisa intsingiselo yenkqubo ye-AAO.
Eyona nto iphambili kwinkqubo ye-AAO kukusebenzisa i-nitrification kunye ne-denitrification yezinto eziphilayo phantsi kweemeko ezahlukeneyo ukuze kufezwe ukususwa kwe-nitrogen, kunye nokusebenzisa iibhaktheriya eziqokelela i-phosphorus ukususa i-phosphorus. Ke ngoko, le nkqubo ifanelekile ngakumbi kwiiprojekthi ezinolawulo olungqongqo longcoliseko lwe-nitrogen kunye ne-phosphorus. Imisebenzi ephambili yezixhobo zonyango lwamanzi amdaka zasemaphandleni zenkqubo ye-AAO igxile kwiimodyuli ezintathu zokusabela, ezizi-anaerobic pool, i-anoxic pool kunye ne-aerobic pool.
Kwindawo yokusabela kwe-anaerobic, ngenxa yokunqongophala kwe-nitrate kunye ne-oksijini kwi-lindle ye-izixhobo zokucoca amanzi amdaka asekhaya zasemaphandleni, iibhaktheriya eziqokelela i-phosphorus zigcina amandla kwiikhompawundi eziqokelela i-phosphorus kwaye zikhuphe ii-phosphate radicals ngaxeshanye, ngelixa ezinye iibhaktheriya zingasebenzi. Kule module yokusabela Ezinye iibhaktheriya azisebenzi kangako kwaye kunzima ukuzikhulisa. Imodule yokusabela kwe-anaerobic isetyenziselwa ukunciphisa i-COD kunye nokulungiselela ukususwa kwe-phosphorus.
Kwimodyuli ye-anoxic reaction, amanzi amdaka ezixhobo zonyango lwamanzi amdaka asemaphandleni anomlinganiselo othile we-nitrate ngaphandle kweoksijini, kwaye iibhaktheriya ezisusa i-nitrite zisebenzisa i-COD ukunciphisa i-nitrate ibe yi-nitrogen, ukukhulula i-alkali, kunye nokufumana amandla okukhula. Ukunciphisa i-COD kunye ne-nitrate nitrogen.
Imodyuli yempendulo ye-aerobic yindawo ephambili yempendulo yezixhobo zonyango lwamanzi amdaka asemaphandleni. Apha, iibhaktheriya ezinika i-nitrogen zidibanisa i-ammonia nitrogen ne-nitrate nitrogen, zisebenzise i-alkalinity kunye ne-oxygen, ii-PAO zifunxa inani elikhulu le-phosphorus, zisebenzise amandla kwi-PHA ukwenza i-polyphosphorus, kwaye ii-OHO ziyaqhubeka nokususa i-COD, ii-PAO, ii-OHO, kwaye iibhaktheriya ezinika i-nitrogen zonke zikhuliswa kule nkqubo. Nciphisa i-COD, i-ammonia nitrogen kunye ne-phosphorus.
Ukususela kuhlalutyo lwemfuno yasemaphandleniunyango lwelindle lwasekhayaIiprojekthi, ukukhethwa kwenkqubo yokucocwa kwamanzi amdaka kufuneka kuhambelane neemfuno zobungakanani bonyango, iimpawu zamanzi amdaka, umgangatho wamanzi amdaka kunye nomzimba wamanzi amdaka. Kwangaxeshanye, inkqubo yokucocwa efanelekileyo kufuneka ikhethwe ngokweempawu zamanzi amdaka asekuhlaleni. Amatyala amaninzi abonisa ukuba izixhobo zokucocwa kwamanzi amdaka zasemaphandleni ze-AAO ziyakwazi ukuziqhelanisa neentlobo ezahlukeneyo zeeprojekthi.
