Raws li kev tshawb fawb nce qib, cov thev naus laus zis rau kev kho cov dej khib nyiab hauv kev lag luam siv cov hlau-carbon microelectrolysis tau dhau los ua qhov paub tab. Cov thev naus laus zis Microelectrolysis tau txais txiaj ntsig zoo hauv kev kho cov dej khib nyiab hauv kev lag luam thiab tau pom kev siv dav hauv kev xyaum engineering.
Lub hauv paus ntsiab lus ntawm microelectrolysis yog qhov yooj yim heev; nws siv cov hlau xeb los tsim cov hlwb electrochemical rau kev kho dej khib nyiab. Txoj kev no siv cov khib nyiab hlau pov tseg ua cov khoom siv raw, tsis tas yuav siv cov khoom siv hluav taws xob, thiab yog li, nws ua rau lub tswv yim ntawm "kev kho cov khib nyiab nrog cov khib nyiab." Tshwj xeeb, hauv kem electrolytic sab hauv ntawm cov txheej txheem microelectrolysis, cov ntaub ntawv xws li cov khib nyiab hlau pov tseg thiab cov pa roj carbon ua haujlwm feem ntau siv ua cov khoom sau. Los ntawm cov tshuaj lom neeg, cov tshuaj Fe2 + ions txo qis tau tsim, uas tuaj yeem txo qee yam khoom hauv cov dej khib nyiab uas muaj cov khoom oxidative.
Tsis tas li ntawd xwb, Fe(OH)2 siv tau rau kev coagulation hauv kev kho dej, thiab cov pa roj carbon activated muaj peev xwm adsorption, tshem tawm cov organic compounds thiab microorganisms zoo. Yog li ntawd, microelectrolysis cuam tshuam nrog kev tsim cov hluav taws xob tsis muaj zog los ntawm lub cell electrochemical hlau-carbon, uas txhawb kev loj hlob thiab kev ua haujlwm ntawm cov microorganisms. Qhov zoo tseem ceeb ntawm txoj kev kho dej electrolysis sab hauv yog tias nws tsis siv zog thiab tuaj yeem tshem tawm ntau yam kuab paug thiab xim ntawm cov dej khib nyiab tib lub sijhawm thaum txhim kho biodegradability ntawm cov tshuaj recalcitrant. Microelectrolysis dej kho tshuab feem ntau yog siv ua ntej kho lossis ntxiv txoj kev ua ke nrog lwm cov txheej txheem kho dej los txhim kho kev kho thiab biodegradability ntawm cov dej khib nyiab. Txawm li cas los xij, nws kuj muaj qhov tsis zoo, nrog rau qhov tsis zoo tseem ceeb yog qhov qeeb qeeb ntawm cov tshuaj tiv thaiv, reactor blockage, thiab cov teeb meem hauv kev kho cov dej khib nyiab siab.
Thaum xub thawj, cov thev naus laus zis microelectrolysis hlau-carbon tau siv rau kev kho cov dej khib nyiab uas muaj ntau yam organic los ntawm kev ua ntawv, tshuaj, coking, cov dej khib nyiab organic uas muaj ntsev ntau, electroplating, petrochemicals, cov dej khib nyiab uas muaj tshuaj tua kab, nrog rau cov dej khib nyiab uas muaj arsenic thiab cyanide. Hauv kev kho cov dej khib nyiab organic, microelectrolysis tsis yog tsuas yog tshem tawm cov organic compounds xwb tab sis kuj txo COD thiab txhim kho biodegradability. Nws pab txhawb kev tshem tawm cov pab pawg oxidative hauv cov organic compounds los ntawm kev adsorption, coagulation, chelation, thiab electro-deposition, tsim cov xwm txheej zoo rau kev kho ntxiv.
Hauv kev siv tiag tiag, kev siv hlau-carbon microelectrolysis tau ua pov thawj tias muaj txiaj ntsig zoo thiab muaj kev cia siab zoo. Txawm li cas los xij, cov teeb meem xws li kev txhaws thiab kev tswj pH txwv tsis pub txoj kev loj hlob ntxiv ntawm cov txheej txheem no. Cov kws tshaj lij ib puag ncig yuav tsum ua kev tshawb fawb ntxiv kom tsim cov xwm txheej zoo dua rau kev siv cov hlau-carbon microelectrolysis thev naus laus zis hauv kev kho cov dej khib nyiab loj.
