Kev tshawb fawb qhia tau hais tias muaj nitrogen ntau dhau rau hauv dej yuav ua rau lub cev dej puas tsuaj thiab cuam tshuam rau qhov zoo ntawm lub cev dej rau qee yam. Cov kev cai tswjfwm ib puag ncig hauv Suav teb tau nce ntxiv txhua xyoo, vim tias kuv lub teb chaws cov dej phwj tuaj yeem tso tawm A-level tus qauv muaj kev txwv nruj rau N cov ntsiab lus, thiab cov qauv dej phwj tuaj yeem nyob deb nroog kuj muaj qee yam kev cai rau nitrogen. Niaj hnub no, Liding Environmental Protection yuav qhia luv luv txog cov thev naus laus zis denitrification zoo dua rau koj.
Kev siv tshuab ua kom denitrification zoo dua yog hais txog kev txhim kho lub peev xwm ua kom cov khoom sib xyaw ua ke uas muaj nitrogen, ua kom tus nqi ua kom denitrification nce ntxiv thiab txhim kho qhov zoo ntawm cov dej khib nyiab los ntawm kev kho cov qauv microbial, ntxiv cov txheej txheem lub cev thiab tshuaj lom neeg thiab txhim kho cov txheej txheem thaum lub sijhawm kho cov pa phem. Kev ua kom denitrification hauv kev kho dej phwj tuaj yeem nyiam tib neeg lub siab, tab sis yuav ua li cas thiaj ua tau zoo rau kev kho denitrification tseem yog ib qho teeb meem nyuaj hauv kev kho dej phwj tuaj.
Cov thev naus laus zis bio-enhanced denitrification siv dav hauv kev kho dej phwj hauv nroog. Los ntawm kev ntxiv cov kab mob tshwj xeeb, cov as-ham lossis cov khoom sib piv rau hauv kev kho mob biological, cov biomass hauv kev kho mob tuaj yeem nce ntxiv, lub peev xwm degradation ntawm lub cev rau cov pa phem tshwj xeeb tuaj yeem tsim tau, thiab tus nqi degradation tuaj yeem txhim kho, yog li tuaj yeem ua tiav lub hom phiaj ntawm kev kho dej phwj. Cov thev naus laus zis muaj cov yam ntxwv ntawm tus nqi qis, kev ua haujlwm siab thiab kev ua qias tuaj tsawg. Ntxiv rau cov nroj tsuag ib txwm muaj, cov kab mob me me uas tau koom nrog hauv lub voj voog nitrogen hauv xwm kuj suav nrog cov kab mob anammox, aerobic denitrifiers, thiab denitrifying phosphorus-tshem cov kab mob thiab lwm yam kab mob tseem ceeb uas ua rau nitrogen metabolism.
Yuav kom ntseeg tau tias qhov kev tso tawm ntawm cov tshuaj nitrogenous hauv cov dej phwj tuaj txog tus qauv, kev ntsuas xws li nce qhov nrawm ntawm cov qauv, nce lub sijhawm khaws cia hydraulic, nce qhov piv ntawm sludge reflux, txo cov sludge load, kho qhov kub ntawm cov tshuaj tiv thaiv, lossis nce qhov tuab ntawm cov khoom sau tuaj yeem siv rau hauv qhov project. Txawm li cas los xij, cov txheej txheem no yuav ua rau cov nqi tsim kho thiab kev ua haujlwm ntawm cov chaw kho dej phwj tuaj ntau dua, ua rau muaj kev cuam tshuam rau kev lag luam ntau dua. Txawm hais tias txoj kev physicochemical txhim kho denitrification technology tau tsim ua ntej, muaj teeb meem xws li tus nqi siab, yooj yim los tsim cov khoom siv tua kab mob, thiab kev ua qias tuaj theem ob. Cov txheej txheem tshiab txhim kho denitrification suav nrog cov txheej txheem luv luv nitrification-denitrification, heterooxygenation-aerobic denitrification txheej txheem, aerobic granular sludge, luv luv nitrification-anammox txheej txheem, thiab lwm yam.
Qhov ntawd yog txhua yam rau qhov teeb meem no, yog xav paub ntxiv, thov mloog Liding qhov kev sib koom hauv qhov teeb meem tom ntej. Liding Environmental Protection tau cog lus rau kev tsim, kev tshawb fawb thiab kev txhim kho, kev tsim khoom thiab kev ua haujlwm ntawm cov khoom siv kho dej phwj tsis muaj chaw nyob hauv thaj chaw kev lag luam ib puag ncig rau kaum xyoo. Kev vam khom rau cov kab tsim khoom tsis siv neeg thiab cov qauv tsis siv neeg, Liding cov khoom muaj qhov zoo pom tseeb hauv qhov zoo thiab kev ua tau zoo. Cov khoom siv kho dej phwj hauv tsev uas tsim tus kheej tuaj yeem siv tau zoo rau cov chaw nyob deb nroog. Yog tias koj xav tau cov kev daws teeb meem khoom thiab cov lus qhia txog kev siv tshuab, txais tos nug. Peb lub vev xaib yog: www.lidingep.com whatsapp: +86 19951179575
