Core Breakthrough: Daim ntawv no qhia txog lub tswv yim tswv yim rau Catalytic Resource Recovery (CRRT) thawj zaug, tsim ib qho "direct-indirect-non-catalytic" qauv kev faib ua kuab paug thiab ib qho "tsib-kev txiav txim siab engineering- ua qhov system," tawg los ntawm qhov kawg ntawm kev kho mob {{6}pib,- tsim kom muaj ntau- nplai raug kaw- voj voog cov peev txheej rov qab los ntawm "rhiav-โรงงาน- kev lag luam chaw ua si," thiab txhawb nqa qhov kev hloov pauv tseem ceeb hauv kev kho dej khib nyiab los ntawm "kev sib ntsib cov qauv tso tawm" mus rau "siab- muaj txiaj ntsig kev hloov pauv."
01 Cov ntsiab lus tshawb fawb
Qhov kev tshuaj xyuas no, raws li "dual-carbon" thiab lub tswv yim kev lag luam ncig, hais txog qhov mob tseem ceeb ntawm cov tshuaj lom neeg, corrosive, thiab complex industrial wastewater muaj pes tsawg leeg los ntawm kev tawm tswv yim tshiab rau Catalytic Resource Recovery (CRRT)-kho cov pa phem li "chemical raw khoom" thiab ua kom tiav ib txhij {2} purification siab thiab rov ua kom zoo dua qub. hloov dua siab tshiab.
Qhov kev tshawb fawb no tsim cov txheej txheem CRRT (Nruam Catalytic Reduction) txoj kev xav thiab cov txheej txheem thev naus laus zis: nws tawm tswv yim tshiab "direct-indirect-non-}catalytic" kev faib tawm cov pa phem, qhia meej txog kev hloov pauv catalytic ntawm ntau hom pa phem; nws piav qhia txog CRRT daim ntawv thov rooj plaub hauv kev lag luam xws li metallurgy, chemical engineering, electronics manufacturing, thiab pharmaceuticals, txheeb xyuas cov txiaj ntsig zoo ntawm kev xaiv rov qab zoo ntawm cov hlau / cov khoom siv hluav taws xob thiab txo lub zog thiab reagent noj; thiab nws tsim ib "tsib-txoj kev txiav txim siab engineering- ua qauv" thiab "ntau- txoj kev siv qhov ntsuas," muab cov kev daws teeb meem zoo los ntawm cov khoom siv catalytic tsim thiab kev txhim kho reactor mus rau kev tsim kho vaj tse.
Qhov kev tshawb fawb no rhuav tshem cov kev txwv ntawm kev kho dej khib nyiab ib txwm siv uas tsom mus rau "kev tshem tawm cov pa phem," muab kev txhawb nqa rau kev tsim kho cov dej hauv kev lag luam uas yog "kev tsis zoo carbon emissions-zero waste operation-siab- tus nqi hloov dua siab tshiab," thiab pab txhawb rau kev ua lag luam ntsuab thiab kev lag luam ncig.
02 Kev Tshawb Fawb Keeb Kwm: Lub raj mis thiab kev hloov pauv xav tau ntawm kev kho dej khib nyiab ib txwm
Raws li lub ntiaj teb "dual carbon" cov hom phiaj, kev lag luam kev kho dej khib nyiab, ua qhov tseem ceeb ntawm cov pa roj carbon monoxide emissions, urgently yuav tsum tau kov yeej qhov tsis xws luag ntawm ib txwm kawg - ntawm - cov qauv kho yeeb nkab:
Cov kev txwv ntawm End- ntawm- Kev Kho Yeeb Nkab: Cov txheej txheem ib txwm ua tsuas yog tsom mus rau kev ua tiav cov qauv kev ua qias tuaj, yooj yim ua rau muaj kuab paug thib ob (xws li kev ua kom cov hlau hnyav rau hauv cov khib nyiab pov tseg thiab tso tawm cov pa hauv tsev cog khoom los ntawm degradation ntawm cov organic teeb meem);
Tsis zoo Adaptability rau Industrial Wastewater: Cov dej khib nyiab muaj cov tshuaj lom heev, corrosive, thiab muaj qhov sib txawv, ua rau nws nyuaj rau cov txheej txheem lom neeg ua haujlwm kom ruaj khov, thaum cov thev naus laus zis physicochemical ntsib cov tsis muaj zog noj thiab cov nqi siab;
