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 neoksijini kwi-lindle yezixhobo zonyango lwelindle zasekhaya 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 lweemfuno zeeprojekthi zonyango lwamanzi amdaka asemaphandleni, ukukhethwa kwenkqubo yonyango lwamanzi amdaka kufuneka kuhlangabezane neemfuno zobungakanani bonyango, iimpawu zamanzi amdaka, umgangatho wamanzi amdaka kunye nomzimba wamanzi amdaka. Kwangaxeshanye, inkqubo yonyango efanelekileyo kufuneka ikhethwe ngokweempawu zamanzi amdaka asekuhlaleni. Amatyala amaninzi abonisa ukuba izixhobo zonyango lwamanzi amdaka asemaphandleni ze-AAO ziyakwazi ukuziqhelanisa kakuhle neentlobo ezahlukeneyo zeeprojekthi.
