1. Kala soocidda tignoolajiyada daaweynta bulaacada nafleyda iyo faa'iidooyinka iyo faa'iido darrada: Habka daaweynta noolaha ee bulaacada waxaa badanaa loo qaybiyaa habka sludge ee firfircoon ee koritaanka hakinta iyo habka biofilm ee koritaanka lifaaqa. Faa'iidooyinka habka sludge ee firfircoon ayaa ah in geeddi-socodku uu qaan-gaaray, cabbirrada hab-socodka waa sahlan tahay in la hagaajiyo, tayada wasakhduna waa wanaagsan tahay, iyo inta badan dhirta lagu daweeyo bulaacada waxay isticmaalaan habka sludge ee firfircoon, iyo khasaaraha ayaa ah in mugga falcelinta qaabdhismeedku aad buu u weyn yahay, dhoobada soo hadhayna waa ka badan tahay, dhoobadana way fududahay in la bararo.
Faa'iidooyinka habka biofilm waa iska caabin xooggan oo saameynaya culeyska, mugga reactor waa yar yahay, balaadhinta dhoobada ma dhici doonto, iyo dhoobada soo hartay waa yar tahay, khasaaraha ayaa ah in tayada biyaha wasakhdu ay yara liidato, gaar ahaan marka biyaha. tayada iyo tirada ayaa si weyn isbeddelaya, biofilm-ka ayaa si weyn u go'ay, tayada biyuhuna si weyn ayay isu beddeshaa.
2. Dhaqan ahaan A/O ama A2/O aragtida denitrification bayooloji: nitrogen ammonia ee bullaacadaha gudaha waxaa loo beddelaa nitrate iyo nitrite by autotrophic nitrifying bakteeriyada leh ogsijiin sida aqbalaha elektarooniga ah inta lagu jiro habka nitrification, ka dibna nitrate iyo nitrite waxaa lagu dhimay gaasta. by heterotrophic denitrifying bakteeriyada si loo yareeyo bulaacada. Sababtoo ah bakteeriyada nitrifying waxay leedahay sifooyin aerobic xoog leh, habka nitrification waa inuu noqdaa aerobic, halka bakteeriyada diidmada dhaqameedku ay isticmaalaan oksijiinta sida aqbalaha elektarooniga si ay u fuliyaan neefsiga hawada ee xaaladaha hawada, iyo kaliya xaalada anaerobic waxay u isticmaalaan nitrate ama nitrite sida aqbalaha elektaroonigga ah. si aad u hesho tamar si ay u abuurto jirka unugga, sidaas darteed bakteeriyada diidmada dhaqameed waxay kaliya ku fulin kartaa denitrification ee deegaanka anoxic. Habka denitrification bayooloji dhaqameed ee la sameeyay sida waafaqsan aragtida sare waxay ka soocaa taangiga anaerobic (faultative) iyo taangiga aerobic, taas oo horseedaysa habsocodka cilladaha sida socodka dheer ee geedi socodka, maalgelinta kaabayaasha sare, hawlgalka nidaamka adag iyo hawlgalka, iyo baahida loo qabo in lagu kabo kaarboonka. ilaha taangiga denitrification.
3. Farsamada MBBR: MBBR waa nooc cusub oo ah reactor tayo sare leh oo isku darsada faa'iidooyinka habka sludge ee firfircoon iyo habka biofilm, kana gudubta cilladaha labada, farsamadeeduna udub dhexaad u ah waa: dooro side bayooloji oo la hakiyey oo leh waxqabad aad u fiican iyo ku dar bakteeriyada denitrification aerobic ee aagga hawada, si loo ogaado nitrification aerobic iyo denitrification waqti iyo meel, oo ay ka gudbaan dhaqanka. A/O ama A2/O aragtida denitrification bayooloji iyo farsamada
