Marka laga eego xogta iibka ee dhawaan la sameeyay, tirada dalabaadka ay heshay Liding Environmental Protection ee qalabka habka AAO ayaa weli sareysa. Maxay yihiin arrimaha macaamiisha ka dhigaya inay si dheeraad ah u aaminaan habkan? Marka xigta, Liding Environmental Protection waxay soo bandhigi doontaa nuxurka habka AAO.
Xudunta habka AAO waa in la isticmaalo nitrification iyo denitrification ee noolaha xaalado kala duwan si loo gaaro ka saarista nitrogen, iyo in la isticmaalo bakteeriyada fosfooraska ururisa si looga saaro fosfooraska. Sidaa darteed, habkani wuxuu aad ugu habboon yahay mashaariicda leh xakamaynta adag ee wasakhowga nitrogen iyo fosfooraska. Hawlaha ugu muhiimsan ee qalabka daaweynta wasakhda gudaha miyiga ee habka AAO waxay ku urursan yihiin saddex qaybood oo falgal ah, kuwaas oo ah barkad anaerobic ah, barkad anoxic ah iyo barkad aerobic ah.
Aagga falgalka anaerobic-ga, sababtoo ah la'aanta nitrate-ka iyo oksijiinta wasakhda ee qalabka daaweynta wasakhda guryaha miyiga, bakteeriyada ururisa fosfooraska waxay tamar ku kaydisaa isku-dhafka fosfooraska waxayna sii deysaa xagjirrada fosfooraska isku mar, halka bakteeriyada kale aysan asal ahaan shaqeyn. Qaybtan falgalka bakteeriyada kale way yar tahay firfircoonideeduna way adag tahay in la koro. Qaybta falgalka anaerobic-ga waxaa loo isticmaalaa in lagu yareeyo COD-ga loona diyaariyo ka saarista fosfooraska.
Qaybta falcelinta anoxic-ga, wasakhda qalabka daaweynta wasakhda guryaha ee miyiga waxay leedahay xaddi gaar ah oo nitrate ah oo aan lahayn oksijiin, bakteeriyada denitrifying-kuna waxay isticmaashaa COD si ay u yareyso nitrate-ka una beddesho nitrogen, u sii dayso alkali, una hesho tamar korriin. Yaree COD-ga iyo nitrate-ka.
Module-ka falgalka aerobic-ga waa aagga falcelinta ugu muhiimsan ee qalabka daaweynta wasakhda guryaha miyiga. Halkan, bakteeriyada nitrifying-ka waxay oksaydhisaa nitrogen ammonia una beddeshaa nitrogen, waxay isticmaashaa alkalinity iyo oksijiin, PAOs waxay nuugtaa xaddi badan oo fosfooraska ah, waxay isticmaashaa tamarta PHA-yada si ay u sameyso polyphosphorus, OHOs-yaduna waxay sii wadaan inay ka saaraan COD-yada, PAO-yada, OHO-yada, iyo bakteeriyada nitrifying-ka dhammaantood ayaa lagu beeraa habkan. Yaree COD-yada, ammonia nitrogen iyo fosfooraska.
Laga soo bilaabo falanqaynta baahida mashaariicda daaweynta wasakhda guryaha ee miyiga, xulashada habka daaweynta wasakhda waa inay buuxisaa shuruudaha cabbirka daaweynta, astaamaha wasakhda, tayada biyaha wasakhda ah iyo jirka biyaha ka soo baxaya. Isla mar ahaantaana, habka daaweynta ee ku habboon waa in la doortaa iyadoo loo eegayo astaamaha wasakhda deegaanka. Kiisas badan ayaa muujinaya in qalabka daaweynta wasakhda miyiga ee AAO uu leeyahay la qabsi wanaagsan oo loogu talagalay noocyada kala duwan ee mashaariicda.
