Tignoolajiyada lagu daweeyo bulaacada gudaha miyiga oo baahsan
bulaacada guryaha ee miyiga ee loo qaybiyo waxay inta badan ka timaadaa biyaha guriga, sida biyaha musqusha, biyaha dhaqida guriga iyo biyaha jikada. Hab-dhaqanka nololeed iyo habka wax-soo-saarka ee dadka deggan miyiga awgeed, tayada biyaha iyo tirada bulaacadaha guryaha ee miyiga la qaybiyey waxay leeyihiin astaamo gobol oo muuqda marka la barbar dhigo bulaacada magaalooyinka, tirada biyaha iyo isku dhafka walxaha biyuhu waa kuwo aan degganayn. Tirada biyuhu aad bay u kala duwan yihiin habeen iyo maalinba, marmarka qaarkood waxay ku jiraan xaalad joojin, iyo isugeynta kala duwanaanshiyaha ayaa aad uga sarreeya qiimaha kala duwanaanshaha magaalada. Isku dhafka dabiiciga ah ee bulaacada miyiga ayaa ah mid aad u sareysa, bulaacada gudahana waxay ka kooban tahay COD, nitrogen, fosfooraska iyo wasakh kale, taas oo ah mid aad u biodegradable, celceliska ugu badnaan ee COD wuxuu gaari karaa 500mg/L.
bulaacada gudaha ee miyiga ee baahsan ayaa leh sifooyinka isbedbeddelka dheecaanka weyn, dareeraha kala firdhisan iyo ururinta adag. Tiknoolajiyada daaweynta bullaacadaha dhexe ee caadiga ah waxay leedahay dhibaatooyinka saamaynta dheecaanka liidata, hawlgal aan xasilloonayn iyo isticmaalka tamarta sare. Iyadoo la tixgelinayo xaaladaha dhaqaale, goobta juqraafiyeed iyo dhibka maaraynta ee miyiga iyo meelaha fog fog, waa isbeddelka horumarinta ee daaweynta wasakhda guryaha ee miyiga ee baahsan si loo qaato tignoolajiyada daaweynta bulaacadaha gudaha ee miyiga ee baahsan iyo horumarinta qalab yar oo isku-dhafan oo lagu daweeyo bulaacada si waafaqsan xaaladaha deegaanka.
Tiknoolajiyada daaweynta ee bulaacada gudaha ee miyiga ah ee loo qaybiyay waxaa loo qaybin karaa saddex qaybood oo ka mid ah mabda'a habka: Marka hore, tiknoolajiyada daaweynta jirka iyo kiimikada, inta badan iyada oo loo marayo hababka daaweynta jirka iyo kiimikada si loo nadiifiyo bulaacada, oo ay ku jiraan xinjirowga, sabbeynta hawada, adsorption, beddelka ion. electrodialysis, osmosis rogaal celis ah iyo ultrafiltration. Midda labaad waa nidaamka daaweynta deegaanka, oo sidoo kale loo yaqaan nidaamka daaweynta dabiiciga ah, kaas oo isticmaala sifaynta ciidda, nuugista dhirta iyo burburka microbial si loo nadiifiyo wasakhda, sida caadiga ah loo isticmaalo: balliga xasilinta, nidaamka daaweynta qoyan ee la dhisay, nidaamka daaweynta percolation dhulka hoostiisa; Midda saddexaad waa habka daaweynta noolaha, inta badan iyada oo loo marayo kala-goynta microorganisms, maadada organic ee biyaha ku jirta walxaha aan noolaha ahayn, taas oo loo qaybiyo habka aerobic iyo habka anaerobic. Oo ay ku jiraan geedi socodka sludge ee firfircoon, habka qulqulka oksaydhka, A / O (habka aerobic anaerobic), SBR (habka isku dhafka dufcada firfircoonida geeddi-socodka), A2/O (anaerobic - anoxic - habka aerobic) iyo MBR (habka bioreactor membrane), DMBR (biofilim firfircoon ) iyo wixi la mida.

Qalabka isku dhafka ah ee daaweynta bulaacada waxay ku saleysan tahay falcelinta biochemical, daawaynta ka hor, biochemical, roobka, jeermiska, dib u soo celinta wasakhda iyo hawlaha kale ee kala duwan ee cutubka oo si dabiici ah loogu daro hal qalab, oo leh maalgashi raasumaal hooseeya, boos yar oo shaqo, hufnaan daaweyn sare, habboon maamulka iyo faa'iidooyin kale oo badan, miyiga waxay leeyihiin rajo ballaaran oo horumarineed iyo faa'iidooyin aan la bedeli karin. Marka lagu daro tignoolajiyada daaweynta bulaacadaha caadiga ah ee hadda jira, shirkadeena waxay soo saartay tiro qalab isku dhafan oo lagu daweeyo wasakhda wasakhda si ay u bixiso xalal kala duwan si loo xalliyo dhibaatada daawaynta wasakhda miyiga ee baahsan. Sida Mashiinka Sifaynta Biyaha ee Koonteeneraysan ee DW, Warshad Daawaynta Bullaacada Baakad Caqli ah (PWT-R, PWT-A), Reactor-ka Daawaynta Biyaha Baakad ee MBF, Dareemiyaha Daawaynta Biyaha Waste Baakad ee MBF, "Dhakhso ah" Biyoreactor-Daawaynta Bullaacadaha Ku shaqeeya Cadceedda. Miisaanka daawaynta waa 3-300 t/d, marka loo eego tayada biyaha daaweynta iyo shuruudaha rakibaadda, Qalabka aan caadiga ahayn waxaa loo qaabayn karaa si loo daboolo baahiyo badan.
