Cilmi-baadhis cilmiyeed ayaa muujisay in natrojiin badan oo soo gasha biyaha ay keenayso eutrophiation jidhka biyaha oo ay saamaynayso tayada biyaha ee jidhka ilaa xad.Shuruudaha maamulka deegaanka ee miyiga ee Shiinaha ayaa sii kordhaya sannad kasta, sababtoo ah dheecaanka daaweynta bulaacada ee waddankayga A heerka dheecaanku wuxuu leeyahay xaddidaad adag oo ku saabsan nuxurka N, iyo shaybaarada bulaacada miyiga ayaa sidoo kale leh shuruudo gaar ah oo loogu talagalay nitrogen.Maanta, Ilaalinta Deegaanka Liding waxay si kooban kuugu soo bandhigi doontaa tignoolajiyada la xoojiyey ee ilkaha.
Tignoolajiyada la wanaajiyey ee denitrification waxaa loola jeedaa hagaajinta awoodda xaalufinta ee xeryahooda nitrogen-ka kooban, kordhinta heerka xaalufka iyo hagaajinta tayada dheecaanka by daaweynta qaab-dhismeedka microbial, ku daray jirka iyo kiimikooyinka hab iyo hagaajinta habka inta lagu guda jiro habka daaweynta wasakhowga.Nadiifinta bayoolojiga ee daaweynta bulaacada ayaa soo jiidatay dareenka dadka, laakiin sida si wax ku ool ah loo fuliyo daaweynta denitrification ayaa weli ah dhibaato adag ee daaweynta bulaacada.
Tignoolajiyada ilko-celinta ee kor loo qaaday ayaa si weyn loogu isticmaalaa daawaynta bullaacadaha miyiga.Marka lagu daro bakteeriyada gaarka ah, nafaqooyinka ama analogs substrate ee daaweynta bayooloji, bayoolajiga biomass ee daaweynta waa la kordhin karaa, awoodda nabaad-guurka ee jidhka ee wasakhowga gaarka ah ayaa la horumarin karaa, heerka hoos u dhacana waa la hagaajin karaa, si loo gaaro yoolka bulaacada daaweynta.Tiknoolajiyadu waxay leedahay sifooyinka qiimaha jaban, waxqabadka sare iyo wasakhowga hooseeya.Marka lagu daro flora-dhaqameedka, microorganisms-ka si cad uga qaybqaatay wareegga nitrogen ee dabeecadda sidoo kale waxaa ka mid ah bakteeriyada anammox, aerobic denitrifiers, iyo diidista bakteeriyada fosfooraska-saarta iyo noolaha kale ee muhiimka ah ee nitrogen-metabolizing.
Si loo hubiyo in sii deynta xeryahooda nitrogenous ee nidaamka bullaacaduhu ay gaaraan heerka caadiga ah, tallaabooyin ay ka mid yihiin kordhinta heerka hawada ee qaab-dhismeedka, kordhinta waqtiga haynta hawo-mareenka, kordhinta saamiga qulqulka qulqulka, yaraynta culeyska qulqulka, hagaajinta heerkulka falcelinta , ama kordhinta dhumucda buuxinta ayaa loo isticmaali karaa mashruuca.Si kastaba ha ahaatee, habkani wuxuu kordhin doonaa dhismaha iyo kharashka hawlgalka ee xarumaha lagu daweeyo bulaacadaha, taasoo keeneysa saameyn dhaqaale oo weyn.In kasta oo habka physicochemical la xoojiyey tignoolajiyada denitrification mar hore, waxaa jira dhibaatooyin ay ka mid yihiin qiimo sare, fududahay in la soo saaro jeermiska jeermiska by-badeecooyinka, iyo wasakhda sare.Hababka cusub ee la xoojiyey ee caadiga ah waxaa ka mid ah habka nitrification-denitrification-gaaban, habka denitrification heterooxygenation-aerobic, dhoobada granular aerobic, habka nitrification-anammox, iwm.
Taasi waa intaas oo dhan arrintaan, si aad macluumaad badan u hesho, fadlan u fiirso wadaagista Liding ee cadadka soo socda.Ilaalinta deegaanka ee daboolaya waxaa ka go'an naqshadeynta, cilmi-baarista iyo horumarinta, soo saarista iyo ka shaqeynta qalabka daaweynta bulaacada ee baahsanaanta ee aagga warshadaha deegaanka muddo toban sano ah.Ku-tiirsanaanta khadadka wax-soo-saarka otomaatiga ah ee heer-sare iyo modular-ka ah, Alaabta daboolka waxay leeyihiin faa'iidooyin muuqda oo tayo iyo waxqabad leh.Qalabka nadiifinta bulaacadaha ee iskood u horumaray ayaa si fiican loogu dabaqi karaa dhulka miyiga ah ee kala firirsan.Haddii aad u baahan tahay xalal badeecado iyo talo farsamo, ku soo dhawoow inaad weydiiso.Websaydhkeena waa: www.lidingep.com whatsapp: +86 19951179575
