Horumarka dhaqaalaha miyiga iyo korodhka dadka, daadinta bulaacada gudaha ee miyiga ayaa sidoo kale sii kordheysa. Si loo ilaaliyo deegaanka miyiga iyo caafimaadka dadka, waxaa loo baahan yahay in la dhiso goobo badan oo lagu daweeyo bulaacadaha si loogu daweeyo wasakhda guryaha ee miyiga. Warshada bulaacada ee magaalada qalab isku dhafan ayaa soo baxday xilligan taariikhiga ah, in hawsheeda shaqadu sida saxda ah, maanta loo fahmo.
Qalabka isku dhafka ah ee warshadda nadiifinta bulaacadaha magaalada waxay inta badan adeegsataa habka daaweynta noolaha ee AO si ay meesha uga saarto wasakhowga organic iyo nitrogen ammonia. Its mabda'a shaqada waa in fasalka A, sababtoo ah fiirsashada sare ee walxaha organic ee bullaacadaha, microorganisms waxay ku sugan yihiin xaalad hypoxia, waqtigan, microorganisms waa microorganisms facultative, waxay dumin doonaan nitrogen organic ee wasakhda galay NH?-N, halka la isticmaalayo isha carbon organic sida deeq elektaroonik ah, ee NO?-N, No? Iyo isticmaalka qaar ka mid ah ilaha kaarboonka organic iyo NH?-N ee isku dhafka walxaha gacanta ee cusub.
Sidaa darteed, fasalka A barkada qalabka daaweynta bulaacada isku dhafan ma aha oo kaliya in uu leeyahay shaqo ka saarida organic gaar ah, la yareeyo culayska organic taangiga aerobic soo socda, kaas oo ku haboon nitrification, laakiin sidoo kale ku tiirsan fiirsashada sare ee walxaha organic jira biyaha ceeriin si ay u dhamaystiraan denitrification, iyo ugu dambeyntii baabi'iyo nitrogen eutrophic wasakhaysan.
Fasalka O, sababtoo ah xoojinta walxaha organic si weyn ayaa loo dhimay, laakiin qalabka daaweynta bullaacadaha isku dhafan ayaa weli leh qadar gaar ah oo ah walxaha organic iyo NH?-N sare. Si loo sameeyo burburka oksaydhka ee walxaha dabiiciga ah, iyo dhamaystirka carbonization, tamarta nitrification waxay u socotaa si habsami leh, haanta oksaydhka xidhiidhka bayoolojiga ee leh culeyska dabiiciga ah ee hooseeya ayaa lagu dejiyay heerka O.
Bakteeriyada aerobic-ka iyo bakteeriyada is-oxygenic waxay inta badan ku jiraan fasalka O-pool ee qalabka isku dhafan ee daaweynta wasakhda. Microorganisms-ka aerobicku miyay u jajabiyaan maadada organic CO? Iyo H? O, Kaarboonka Inorganic ama CO ee hawada ku jira? Ilaha nafaqeynta ahaan, MAYA ee bullaaacadaha?-N,MAYA?-N waxay isu rogi doontaa N?. Wasakhda barkada O waxay ku socotaa barkadda A, taasoo bixisa soo-dhoweeyaha elektarooniga ah ee barkadda A, oo ugu dambeyntii baabi'inaysa wasakhowga nitrogen iyadoo loo marayo denitrification.
Qalabka isku dhafka ah ee dhirta lagu daweeyo bulaacadaha magaalada ee gobollada kala duwan waxay u baahan yihiin inay doortaan tignoolajiyada daaweynta bullaacadaha ee ku habboon iyadoo loo eegayo xaaladda gaarka ah ee meelaha miyiga ah, iyo sidoo kale waxay u baahan yihiin inay tixgeliyaan suurtagalnimada, dhaqaalaha iyo saameynta deegaanka ee tignoolajiyada. Jiading ilaalinta deegaanka isku dhafan qalabka daaweynta bulaacaduhu wuxuu dabooli karaa baahida 0.3-isku-dhafka 10,000 tan ee daaweynta wasakhda, iyo 9 taxane ah oo alaab ah ayaa loo dooran karaa si xor ah, marka loo eego xaalado kala duwan.
