Poganizira za malonda aposachedwa, chiwerengero cha maoda omwe Liding Environmental Protection ya zida zogwirira ntchito za AAO chalandirabe chikukwera. Ndi zinthu ziti zomwe zimapangitsa makasitomala kudalira njirayi kwambiri? Kenako, Liding Environmental Protection idzayambitsa mfundo yaikulu ya njira ya AAO.
Cholinga chachikulu cha njira ya AAO ndikugwiritsa ntchito nitrification ndi denitrification ya zamoyo pansi pa mikhalidwe yosiyanasiyana kuti athetse nayitrogeni, ndikugwiritsa ntchito mabakiteriya osonkhanitsa phosphorous kuti achotse phosphorous. Chifukwa chake, njira iyi ndi yoyenera kwambiri pamapulojekiti omwe ali ndi ulamuliro wokhwima wa nayitrogeni ndi phosphorous. Ntchito zazikulu za zida zotsukira zinyalala zakumidzi za njira ya AAO zimayikidwa m'magawo atatu a reaction, omwe ndi dziwe lopanda mpweya, dziwe lopanda mpweya ndi dziwe lopanda mpweya.
Mu gawo la anaerobic reaction, chifukwa cha kusowa kwa nitrate ndi oxygen m'zimbudzi za zida zotsukira zinyalala zakumidzi, mabakiteriya osonkhanitsa phosphorous amasunga mphamvu muzinthu zomwe zimasonkhanitsa phosphorous ndikutulutsa ma phosphate radicals nthawi yomweyo, pomwe mabakiteriya ena sagwira ntchito kwenikweni. Mu gawo ili la reaction, mabakiteriya ena sagwira ntchito kwambiri ndipo ndi ovuta kukula. Gawo la anaerobic reaction limagwiritsidwa ntchito kuchepetsa COD ndikukonzekera kuchotsa phosphorous.
Mu gawo la anoxic reaction, zimbudzi za zida zotsukira zinyalala zakumidzi zimakhala ndi nitrate yochuluka popanda mpweya, ndipo mabakiteriya oletsa nitrizing amagwiritsa ntchito COD kuchepetsa nitrate kukhala nayitrogeni, kutulutsa alkali, ndikupeza mphamvu kuti zikule. Kuchepetsa COD ndi nayitrogeni wa nitrate.
Gawo la aerobic reaction ndilo gawo lalikulu la reaction la zida zotsukira zinyalala zakumidzi. Apa, mabakiteriya opatsa nitrifying amawonjezera ammonia nayitrogeni kukhala nitrate nayitrogeni, amadya alkalinity ndi oxygen, ma PAO amayamwa phosphorous yambiri, amagwiritsa ntchito mphamvu zomwe zili mu ma PHA kuti apange polyphosphorus, ndipo ma OHO amapitiliza kuchotsa COD, ma PAO, ma OHO, ndipo mabakiteriya opatsa nitrifying onse amakula munjira imeneyi. Kuchepetsa COD, ammonia nayitrogeni ndi phosphorous.
Kuchokera ku kusanthula kwa kufunika kwa mapulojekiti oyeretsera zinyalala m'nyumba zakumidzi, kusankha njira yoyeretsera zinyalala kuyenera kukwaniritsa zofunikira za kukula kwa kuyeretsa, mawonekedwe a zinyalala, ubwino wa madzi otuluka m'madzi ndi madzi otuluka. Nthawi yomweyo, njira yoyenera yoyeretsera iyenera kusankhidwa malinga ndi mawonekedwe a zinyalala zakomweko. Milandu yambiri ikuwonetsa kuti zida zoyeretsera zinyalala zakumidzi za AAO zimatha kusintha bwino mitundu yosiyanasiyana ya mapulojekiti.
