Cilmi-baaris cilmiyeed ayaa muujinaysa in nitrogen badan oo soo gasha biyaha ay sababi doonto in jirka biyaha uu ka baxo oo uu saameeyo tayada biyaha ee jirka biyaha ilaa xad gaar ah. Shuruudaha maamulka deegaanka miyiga ee Shiinaha ayaa sii kordhaya sannad kasta, sababtoo ah dheecaanka heerka A ee daaweynta wasakhda ee dalkayga wuxuu leeyahay xaddidaadyo adag oo ku saabsan heerka N, muunadaha wasakhda miyigana waxay sidoo kale leeyihiin shuruudo gaar ah oo ku saabsan nitrogen. Maanta, Ilaalinta Deegaanka ee Liding ayaa si kooban kuu soo bandhigi doonta tignoolajiyada denitrification ee la xoojiyay.
Tiknoolajiyadda denitrification ee la xoojiyay waxay tilmaamaysaa hagaajinta awoodda burburka ee isku-dhafka nitrogen-ka ku jira, kordhinta heerka burburka iyo hagaajinta tayada wasakhda iyadoo la daaweynayo qaab-dhismeedka microbial-ka, ku darista hababka jireed iyo kiimikada iyo hagaajinta habka inta lagu jiro habka daaweynta wasakhda. Denitrification-ka bayoolojiga ee daaweynta wasakhda ayaa soo jiidatay dareenka dadka, laakiin sida si wax ku ool ah loogu sameeyo daaweynta denitrification-ka weli waa dhibaato adag oo ku jirta daaweynta wasakhda.
Tiknoolajiyadda denitrification-ka ee bio-enhanced ayaa si weyn loogu isticmaalaa daaweynta wasakhda miyiga. Iyadoo lagu darayo bakteeriyada gaarka ah, nafaqooyinka ama walxaha kale ee substrate-ka ah daaweynta bayoolojiga, bayoolajiga ku jira daaweynta waa la kordhin karaa, awoodda burburka jirka ee wasakhda gaarka ah ayaa la horumarin karaa, heerka burburkana waa la hagaajin karaa, sidaas darteedna waxaa lagu gaari karaa yoolka daaweynta wasakhda. Tiknoolajiyadda waxay leedahay astaamo kharash yar, waxqabad sare iyo wasakheyn hoose. Marka laga soo tago dhirta dhaqameed, noolaha yaryar ee si cad uga qayb qaatay wareegga nitrogen ee dabiiciga ah waxaa sidoo kale ka mid ah bakteeriyada anammox, denitrifiers-ka aerobic, iyo bakteeriyada denitrifying fosfooraska-ka-saarta iyo noolaha kale ee muhiimka ah ee dheef-shiid kiimikaadka nitrogen.
Si loo hubiyo in sii deynta isku-dhafka nitrogenous ee nidaamka wasakhda ay gaarto heerka, waxaa la cabbiraa sida kordhinta heerka hawo-qaadista ee qaab-dhismeedka, kordhinta waqtiga haynta haydarooliga, kordhinta saamiga dib-u-celinta wasakhda, yaraynta culeyska wasakhda, hagaajinta heerkulka falcelinta, ama kordhinta dhumucda buuxinta ayaa loo isticmaali karaa mashruuca. Si kastaba ha ahaatee, habkani wuxuu kordhin doonaa kharashka dhismaha iyo hawlgalka ee xarumaha daaweynta wasakhda, taasoo keenta saameyn dhaqaale oo weyn. In kasta oo habka fiisikochemical-ga ee la xoojiyay ee tignoolajiyada denitrification hore loo sameeyay, waxaa jira dhibaatooyin sida kharash sare, si fudud loo soo saari karo waxyaabaha ka soo baxa jeermiska, iyo wasakhowga labaad. Hababka cusub ee la xoojiyay ee denitrification waxaa ka mid ah habka nitrification-denitrification ee muddada gaaban, habka heterooxygenation-aerobic denitrification, dhoobada granular aerobic, habka nitrification-anammox ee muddada gaaban, iwm.
Intaas oo dhan waa arrintaan, si aad u hesho macluumaad dheeraad ah, fadlan fiiro gaar ah u yeelo wadaagga Liding ee cadadka xiga. Liding Environmental Protection waxay ka go'an tahay naqshadeynta, cilmi-baarista iyo horumarinta, soo saarista iyo hawlgalka qalabka nidaamka daaweynta wasakhda baahsan ee aagga warshadaha deegaanka muddo toban sano ah. Iyada oo ku tiirsan khadadka wax soo saarka otomaatiga ah ee heer sare ah iyo kuwa moodeel ah, alaabada Liding waxay leeyihiin faa'iidooyin muuqda oo ku saabsan tayada iyo waxqabadka. Qalabka daaweynta wasakhda guryaha ee iskood u horumarsan ayaa si fiican loogu dabaqi karaa meelaha miyiga ah ee kala firirsan.
