Ukuqwalasela idatha yokuthengisa yakutshanje, inani lee-odolo ezifunyenwe yi-Liding Environmental Protection kwi-AAO yenkqubo yezixhobo zihlala ziphezulu. Zeziphi izinto ezenza abathengi bathembe le nkqubo ngakumbi? Okulandelayo, uKhuseleko lweNdalo eLiding luya kwazisa isiseko senkqubo ye-AAO.
Ingundoqo yenkqubo ye-AAO kukusebenzisa i-nitrification kunye ne-denitrification yezinto eziphilayo phantsi kweemeko ezahlukeneyo ukuphumeza ukususwa kwe-nitrogen, kunye nokusebenzisa i-phosphorus-accumulating bacteria ukususa i-phosphorus. Ngoko ke, le nkqubo ifaneleke ngakumbi kwiiprojekthi ezinolawulo olungqongqo lwe-nitrogen kunye nokungcola kwe-phosphorus. Imisebenzi ephambili yezixhobo zokucocwa kogutyulo lwasekhaya lwasemaphandleni kwinkqubo ye-AAO igxininiswe kwiimodyuli ezintathu zokusabela, ezizii-anaerobic pool, i-anoxic pool kunye ne-aerobic pool.
Kwindawo yokusabela kwe-anaerobic, ngenxa yokunqongophala kwe-nitrate kunye neoksijini kugutyulo lwezixhobo zokucoca ugutyulo lwamanzi amdaka asemaphandleni, i-phosphorus eqokelela iibhaktheriya igcina amandla kwiikhompawundi eziqokelela i-phosphorus kwaye ikhuphe i-phosphate radicals ngaxeshanye, ngelixa ezinye iibhaktheriya zingasebenzi. . Kule modyuli yokusabela Ezinye iibhaktheriya azisebenzi kwaye kunzima ukukhula. Imodyuli ye-anaerobic reaction isetyenziselwa ukunciphisa i-COD kunye nokulungiselela ukususwa kwe-phosphorus.
Kwimodyuli ye-anoxic reaction, i-sewage yezixhobo zokucocwa kwamanzi asemaphandleni asemaphandleni anenani elithile le-nitrate ngaphandle kwe-oksijini, kwaye iibhaktheriya ze-denitrifying zisebenzisa i-COD ukunciphisa i-nitrate kwi-nitrogen, ukukhulula i-alkali, kunye nokufumana amandla okukhula. Nciphisa iCOD kunye nenitrogen yenitrate.
Imodyuli yokusabela kwe-aerobic yeyona ndawo ingundoqo yokusabela kwisixhobo sokucocwa kogutyulo lwasekhaya olusemaphandleni. Apha, iibhaktheriya ze-nitrifying oxidize ammonia nitrogen to nitrate nitrogen, sebenzisa ialkalinity kunye neoksijini, i-PAOs ifunxa inani elikhulu le-phosphorus, isebenzisa amandla kwi-PHAs ukudibanisa i-polyphosphorus, kunye ne-OHOs ziyaqhubeka nokususa i-COD, i-PAOs, i-OHOs, kunye ne-nitrifying bacteria zonke zikhulile. kule nkqubo. Ukunciphisa i-COD, i-ammonia nitrogen kunye ne-phosphorus.
Ukususela kuhlalutyo lweemfuno zeeprojekthi zokucocwa kwamanzi amdaka asemaphandleni, ukhetho lwenkqubo yokucocwa kwamanzi amdaka kufuneka luhlangabezane neemfuno zesikali sokucocwa, iimpawu zogutyulo, umgangatho wamanzi amdaka kunye nokukhutshwa kwamanzi amdaka. Ngelo xesha, inkqubo efanelekileyo yokonyango kufuneka ikhethwe ngokweempawu zamanzi amdaka asekuhlaleni. Amatyala amaninzi abonisa ukuba izixhobo zokucoca ugutyulo lwasemaphandleni lwe-AAO zinokuziqhelanisa kakuhle neentlobo ezahlukeneyo zeeprojekthi.
