Feem ntau hais lus,Toptitechqhia rau koj tias muaj ntau txoj hauv kev los tshem tawm thiab txo qhov scaling
thiab nag lossis daus ntawm electrode scaling los ntawm concentration polarization:
Siv inverted electrodes:
tsis tu ncua pauv electrodes los hloov cov kev tsiv teb tsaws ntawm ions. Raws li qhov tseeb
qhov xwm txheej, cov electrodes feem ntau pauv txhua 2-8 teev. Nyob rau hauv xyoo tas los no, nquag
Cov khoom siv hluav taws xob tsis siv neeg tau siv nyob hauv tsev thiab txawv teb chaws, li ntawm 15-30 feeb. Rau
lub sijhawm ntev, txawm tias muaj nag lossis daus me ntsis, nws yuav raug tshem tawm zoo, tab sis qhov zoo
cov kev xav tau ntawm cov electrode kuj yog siab heev vim yog nquag electrode reversal, thiab cov
electrode poob yog loj, yog li nws yog ib qho tsim nyog los xaiv cov khoom zoo, muaj zog corrosion-resistant electrode
cov ntaub ntawv.
2. Txoj kev Pickling:
Muaj ib txwm ib tug me me ntawm precipitated nplai generated thaum lub sij hawm ua hauj lwm ntawm lub
electrodialysis, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas muaj dej tsis zoo. Tom qab accumulating rau ib qho twg, nws
tsis tuaj yeem raug tshem tawm tag nrho txawm tias hloov cov electrodes. Lub sijhawm no, pickling yog xav tau.
deal nrog. Raws li qhov xwm txheej, kev kho mob tsis tu ncua yog ib txoj hauv kev yooj yim thiab siv tau zoo
tshem tawm nag lossis daus yam tsis muaj dismantling cov cuab yeej. Lub voj voog nyob ntawm qhov xwm txheej tiag tiag,
Feem ntau, 1 feem pua mus rau 2 feem pua ntawm hydrochloric acid yog siv los ntxuav cyclic.
3. Limiting txoj kev tam sim no:
nruj me ntsis tswj qhov ua hauj lwm tam sim no ntawm electrodialysis, thiab ua kom nws ib txwm qis dua qhov txwv
tam sim no thaum polarization tshwm sim, thiaj li zam dhau tiam ntawm polarization.
4. Dismantling thiab ntxuav raws li qhov chaw kawg: tom qab lub sijhawm ntev ntawm kev ua haujlwm, yog tias muaj kev cuam tshuam sab hauv
yog qhov hnyav thiab tsis tuaj yeem raug tshem tawm los ntawm cov txheej txheem saum toj no, disassemble lub cuab yeej thiab ntxuav lub
partitions thiab diaphragms.
5. Yuav kom txo tau sedimentation thiab scaling, nws tseem ceeb heev kom ntxiv dag zog rau lub
kev kho cov dej nyoos. Tshem tawm cov khib nyiab, qee yam tshuaj colloidal, thiab cov organic
impurities nyob rau hauv tej yam ntuj tso dej yuav tiv thaiv los yog txo sedimentation thiab scaling. Pretreatment tuaj yeem ua tau
siv los tshem tawm cov tawv tawv ntawm cov dej nyoos, uas tuaj yeem ua tau zoo Tiv thaiv kev scaling.
