Marka la eego xogta iibka ee dhowaan, tirada amarada ay heshay Ilaalinta Deegaanka Liding ee qalabka habka AAO ayaa weli ah mid sarreeya. Maxay yihiin arrimaha ka dhigaya macaamiishu inay ku kalsoonaadaan habkan? Marka xigta, Ilaalinta Deegaanka Liding ayaa soo bandhigi doonta nuxurka habka AAO.
Xuddunta habka AAO waa in la isticmaalo nitrification iyo denitrification ee noolaha ee xaaladaha kala duwan si loo gaaro ka saarista nitrogen, iyo in la isticmaalo bakteeriyada fosfooraska ururisa si looga saaro fosfooraska. Sidaa darteed, habkani wuxuu ku habboon yahay mashaariicda leh xakamaynta adag ee nitrogen iyo fosfooraska wasakhaysan. Hawlaha ugu muhiimsan ee qalabka daaweynta bullaacadaha guriga ee miyiga ee habka AAO waxay ku urursan yihiin saddex qaybood oo falcelin ah, kuwaas oo ah barkadda anaerobic, barkadda anoxic iyo barkada aerobic.
Goobta falcelinta anaerobic-ka, sababtoo ah la'aanta nitrate iyo oksijiin ee wasakhda qalabka daaweynta wasakhda guriga ee miyiga, fosfooraska ururinta bakteeriyada waxay ku kaydisaa tamarta xeryahooda fosfooraska-urursan waxayna sii daayaan radicals fosfooraska isku mar, halka bakteeriyada kale asal ahaan aysan shaqayn. . Qaybtan falcelinta Bakteeriyada kale aad ayay u yar tahay wayna adagtahay inay koraan. Habka falcelinta anaerobic waxaa loo isticmaalaa in lagu dhimo COD loona diyaariyo ka saarista fosfooraska.
Qeybta falcelinta anoxic-ka, bulaacada qalabka daaweynta bulaacada guriga ee miyiga waxay leedahay qadar gaar ah oo nitrate ah oo aan lahayn oksijiin, iyo bakteeriyada diida waxay isticmaashaa COD si loo yareeyo nitrate ilaa nitrogen, sii daayo alkali, iyo helitaanka tamarta koritaanka. Iska yaree COD iyo Nitrate nitrogen.
Qaybta falcelinta aerobic-ka waa aagga falcelinta udub-dhexaadka u ah qalabka daaweynta bulaacadaha guriga ee miyiga. Halkan, bakteeriyada nitrifying oxidize ammonia nitrogen si ay nitrate nitrogen, baabbi'in alkalinity iyo ogsijiin, PAOs nuugo xaddi badan oo fosfooraska, isticmaalaan tamarta ee PHAs si ay u abuuraan polyphosphorus, iyo OHOs sii wadaan in ay ka saaraan COD, PAOs, OHOs, iyo bakteeriyada nitrifying dhamaantood waa koray. habkan. Iska yaree COD, nitrogen ammonia iyo fosfooraska.
Laga soo bilaabo falanqaynta baahida mashruucyada daaweynta bulaacadaha gudaha ee miyiga, xulashada habka daaweynta bulaacada waa inay buuxisaa shuruudaha miisaanka daaweynta, sifooyinka wasakhda, tayada biyaha wasakhaysan iyo dheecaanka jirka biyaha. Isla mar ahaantaana, habka daaweynta ku habboon waa in lagu doortaa si waafaqsan sifooyinka bullaacadaha maxalliga ah. Xaalado badan ayaa muujinaya in AAO qalabka daaweynta bulaacada ee miyiga ay si fiican ula qabsanayaan noocyada kala duwan ee mashaariicda.
