Tshiab Sulfur autotrophic Dej Tuag Tag Nrho Cov Kev Kho Mob Nitrogen Kho

Nrog rau cov txheej txheem kev tso dej ntau zuj zus ntxiv, tag nrho cov ntsuas nitrogen emissions tau dhau los ua nruj dua. Lub tuam tsev tiv thaiv ib puag ncig hauv tebchaws tau teev tseg tias cov khoom siv kho dej phwj uas twb muaj lawm yuav tsum ua raws li tag nrho cov txheej txheem nitrogen emission tsawg dua lossis sib npaug li 12mg / L.

Feem ntau ntawm cov dej phwj uas twb muaj lawm uas muaj ammonia nitrogen txais A / O biochemical kev kho mob, uas yog, ammonia nitrogen thiab tag nrho cov nitrogen raug tshem tawm los ntawm nitrification thiab denitrification ntawm cov kab mob. Microbial nitrification yog txheej txheem ntawm kev hloov ammonia nitrogen hauv cov dej phwj tuaj rau hauv nitrite thiab nitrate, thiab denitrification yog txheej txheem ntawm kev hloov nitrite thiab nitrate rau hauv cov pa nitrogen. Kev tshem tawm ntawm tag nrho cov nitrogen feem ntau yog nyob ntawm qib ntawm nitrification thiab denitrification.

Hauv kev tsoos Nitricification thiab Denitrification Phwj Kev Kho Mob, cov av nkos sib xyaw hauv lub aerobic tshuaj tank rov qab mus rau anoxic tshuaj tiv thaiv tank. Nyob rau hauv lub tswv yim, qhov loj dua rov qab piv, tau ntau dua cov nitrogen tshem tawm, tab sis ib qho kev rov qab loj dua yuav ua rau muaj kev ua haujlwm siab.

Qee cov dej khib nyiab hauv kev lag luam, xws li roj refinery dej khib nyiab, muaj cov dej tsis zoo, muaj ammonia nitrogen thiab tag nrho cov nitrogen, cov organic carbon tsawg hauv dej, thiab complex nitrogen-muaj cov organic teeb meem hauv cov dej khib nyiab yog qhov nyuaj rau siv los ntawm cov kab mob rau denitrification, yog li cov khoom siv tsis zoo. tag nrho cov nitrogen hauv cov kua dej qee zaum tsis ua raws li tus qauv.

Tsis tas li ntawd, cov dej phwj teb cov ntoo uas tau ua thiab ua haujlwm nyob rau hauv thaum ntxov theem tsuas yog tsim cov tshuab hluav taws xob, tsis muaj cov tshuab tsis muaj npe. Yog tias qhov kev txwv tsis pub tshaj tawm txoj kev txhim kho, nws yuav xav tau qhov chaw loj thiab kev nqis peev, uas tseem yuav siv cov khoom siv dej phwj tuaj thiab kev hloov pauv ntawm cov dej phwj tuaj.

Nyob rau tib lub sijhawm, qee cov dej phwj tuaj muaj ammonia nitrogen siab thiab tag nrho cov ntsiab lus nitrogen, thiab cov pa roj carbon monoxide kuj tsis txaus. Cov pa roj carbon monoxide yuav tsum tau ntxiv los ua kom denitrification ua tau zoo, uas tseem ua rau tus nqi kho dej phwj tuaj.

SAD autotrophic denitrification thev naus laus zis yog ib puag ncig bioremediation thev naus laus zis tshiab uas tuaj yeem ua tiav kev tshem tawm cov nitrate nitrogen hauv dej tsis ntxiv cov organic carbon. Nws muaj cov txiaj ntsig tseem ceeb xws li kev ua haujlwm siab denitrification, tus nqi ua haujlwm qis, thiab kev siv ntau yam. Nws yog tsuas yog siv los ua qhov sib sib zog nqus denitrification unit rau tag nrho cov nitrogen txhim kho hauv cov dej phwj tuaj kho thiab siab nitrate nitrogen muaj kev txhim kho dej khib nyiab.

Cov tub ntxhais ntawm autotrophic thev naus laus zis yog tus tsim kev loj hlob ntawm bio-electron cov tsheb ciav hlau thiab cov khoom lag luam uas tsis muaj zog sib sib zog nqus cov txheej txheem depitrification. Nyob rau hauv lub xeem bio-electron cov cab kuj, cov kev faib tawm ntawm alkalinity pub tuaj yeem sib npaug ntawm cov txheej txheem denitrification thiab ua tiav kev txij nkawm ntawm kev ua haujlwm ntawm roj ntsha; Cov lus qhia ntawm cov neeg pub tshuaj hluav taws xob ntau ntxiv tuaj yeem txhawb cov metabolic txuas ntawm cov kab mob metupling ntawm cov kab mob metupling ntawm cov kab mob me thiab ua tiav kev ua kom yus tus kheej ntawm cov txheej txheem kev tiv thaiv tus kheej. Lub ntsiab lus ntawm autotrophic thev naus laus zis yog tias ntau lub tshuab hluav taws xob ua kom nrawm ntawm cov kev coj ua ntawm cov tshuaj tiv thaiv kab mob

Lub Sulphur autorophic zam tag nrho cov kev kho mob nitrogen kev tsim los ntawm Jieyoo Technology suav nrog Arototrophic reactor, ib qho dej hauv lub cuab yeej siv dej thiab cov khoom siv ncig. Cov cuab yeej siv reactor tau sau nrog cov khoom lim heterogeneous fert. Cov khoom siv dej hauv cov twj tso kua dej suav nrog cov dej tso kua roj, cov dej relet inlet cov yeeb nkab thiab dej inlet nyaim. Cov dej inlet Flow Flwg Inlet cov yeeb nkab inlet cuab tam ntawm cov dej hluav taws xob raws li cov dej preset Inlet Flow Flow. Cov khoom siv ncig ua si suav nrog cov yeeb nkab reflux, ib qho reflux valve thiab reflection 'meviv. Lub valve reflection thiab lub reflux flow 'meter nruab rau tswj tau qhov qhib thiab kaw ntawm Reflux Valve raws li Retrux ntws ntawm lub reflux ntws mus los. Sab saum toj ntawm cov reactor yog muab nrog cov nitrogen qhov hluav taws xob, thiab sab phab ntsa ntawm sab saum toj ntawm cov dej ntws tawm.

Los ntawm kev teeb tsa cov sulfur autotrophic reactor, cov khoom siv dej nkag thiab cov khoom siv ncig, tom qab cov dej phwj tuaj los ntawm lub twj tso kua mis, qhov ceev ntawm qhov sib txawv zaus lub cev muaj zog ntawm cov dej inlet twj tso kua mis yog tswj raws li cov txheej txheem ntws ntawm cov twj tso kua mis. dej inlet flowmeter, yog li tswj lub sijhawm nyob ntawm cov dej phwj tuaj hauv cov sulfur autotrophic reactor, kom tag nrho cov nitrogen hauv cov dej phwj tuaj yeem tswj tau los ntawm kev ntws. tus nqi yog hloov mus rau hauv nitrogen gas los ntawm cov kab mob nyob rau hauv qhov kev txiav txim ntawm cov khoom lim dej sib xyaw thiab tso tawm, ua kom nws cov kev ua haujlwm siab denitrification, ua siab ntev rau qhov kub thiab txias, tsis tshua muaj nqi, kev ua haujlwm yooj yim thiab kev saib xyuas yooj yim.
