Uma sibheka kusukela kudatha yokuthengisa yakamuva, inani lama-oda atholwe yi-Liding Environmental Protection yemishini yenqubo ye-AAO lihlala liphezulu. Yiziphi izici ezenza amakhasimende athembe le nqubo ngokwengeziwe? Okulandelayo, I-Liding Environmental Protection izokwethula ingqikithi yenqubo ye-AAO.
Umongo wenqubo ye-AAO ukusebenzisa i-nitrification kanye ne-denitrification yezinto eziphilayo ngaphansi kwezimo ezahlukene ukuze kuzuzwe ukukhishwa kwe-nitrogen, nokusebenzisa amabhaktheriya aqoqa i-phosphorus ukuze asuse i-phosphorus. Ngakho-ke, le nqubo ifaneleka kakhulu kumaphrojekthi alawulwa ngokuqinile ukungcola kwe-nitrogen ne-phosphorus. Imisebenzi esemqoka yemishini yokuhlanza indle yasekhaya yenqubo ye-AAO igxile kumamojula amathathu okusabela, okuyi-anaerobic pool, i-anoxic pool kanye ne-aerobic pool.
Endaweni yokusabela kwe-anaerobic, ngenxa yokuntuleka kwe-nitrate nomoya-mpilo ekukhunjweni kwendle yemishini yokuhlanza indle yasemaphandleni, amagciwane aqongelela i-phosphorus agcina amandla ezinhlanganisela eziqongelela i-phosphorus futhi akhulule ama-phosphate radicals ngesikhathi esifanayo, kuyilapho amanye amagciwane engasebenzi. . Kule mojuli yokusabela Amanye amagciwane awasebenzi futhi anzima ukukhula. Imojula ye-anaerobic reaction isetshenziselwa ukunciphisa i-COD nokulungiselela ukususwa kwe-phosphorus.
Kumojula ye-anoxic reaction, indle yemishini yokuhlanza indle yasemaphandleni inenani elithile le-nitrate ngaphandle kwe-oxygen, futhi amabhaktheriya e-denitrifying asebenzisa i-COD ukunciphisa i-nitrate ku-nitrogen, ukukhulula i-alkali, nokuthola amandla okukhula. Yehlisa i-COD ne-nitrate nitrogen.
Imojula ye-aerobic reaction iyindawo eyinhloko yokusabela yemishini yokuhlanza indle yasemaphandleni. Lapha, amabhaktheriya afaka i-nitrifying oxidize ammonia nitrogen ku-nitrate nitrogen, adle i-alkalinity nomoya-mpilo, ama-PAO amunca inani elikhulu le-phosphorus, asebenzise amandla aku-PHAs ukuze ahlanganise i-polyphosphorus, futhi ama-OHO ayaqhubeka nokususa ama-COD, ama-PAO, ama-OHO, kanye namabhaktheriya e-nitrifying akhulile. kule nqubo. Yehlisa i-COD, i-ammonia nitrogen ne-phosphorus.
Kusukela ekuhlaziyweni kwesidingo samaphrojekthi wokuhlanza indle ezindlini zasemakhaya, ukukhethwa kwenqubo yokuhlanza indle kufanele kuhlangabezane nezidingo zesikali sokuhlanza, izici zokukhucululwa kwendle, ikhwalithi yamanzi angcolile kanye nomzimba wamanzi wokulahla. Ngesikhathi esifanayo, inqubo yokwelashwa efanele kufanele ikhethwe ngokuvumelana nezici zendle yendawo. Amacala amaningi abonisa ukuthi imishini ye-AAO yokuhlanza indle yasemaphandleni inokuvumelana okuhle nezinhlobo ezahlukene zamaphrojekthi.
