Lub hauv paus ntsiab lus ntawm electrochemicaldej kho titanium anodethev naus laus zis yog ua kom muaj kuab paug rau cov tshuaj tiv thaiv hluav taws xob ncaj qha lossis tsis ncaj qha hluav taws xob hloov pauv ntawm cov electrode, uas yog ncaj qha electrolysis thiab indirect electrolysis.
Direct electrolysis yog hais txog kev tshem tawm cov pa phem ntawm cov dej khib nyiab los ntawm kev oxidation ncaj qha los yog txo ntawm cov electrode. Direct electrolysis tuaj yeem muab faib ua cov txheej txheem anode thiab txheej txheem cathode; Indirect electrolysis yog hais txog kev siv cov tshuaj redox uas tsim los ntawm electrochemistry ua reactants los yog catalysts los hloov cov pa phem rau hauv cov tshuaj lom neeg tsawg. Indirect electrolysis tuaj yeem muab faib ua cov txheej txheem thim rov qab thiab cov txheej txheem tsis thim rov qab.
1, Kev faib tawm ntawm Electrochemical Water Treatment Technologies
1. Electrocoagulation electric flotation method: Nyob rau hauv qhov kev txiav txim ntawm sab nraud voltage, lub anode yog oxidized los tsim ib tug loj tus naj npawb ntawm cations, uas ces tsim colloids condense cov pa phem nyob rau hauv cov dej khib nyiab. Nyob rau tib lub sijhawm, ntau cov pa roj hydrogen yog tsim los ntawm cathode los tsim microbubbles thiab ua raws li flocs rau flotation. Txoj kev no hu ua electrocoagulation electric flotation.
2. Electrodeposition method: Los ntawm kev siv qhov sib txawv ntawm cov hlau sib txawv hauv cov electrolyte, cov hlau soluble nyob rau hauv lub xeev dawb los yog khi yog precipitated ntawm cathode. Lub peev xwm tsim nyog yog tus yuam sij rau qhov tshwm sim ntawm electrodeposition.
3. Electrochemical oxidation txoj kev: Electrochemical oxidation yog muab faib ua oxidation ncaj qha thiab indirect oxidation, uas belongs rau cov txheej txheem anodic tshuaj tiv thaiv. Direct oxidation yog hais txog kev hloov pauv ncaj qha ntawm cov pa phem rau hauv cov khoom tsis zoo los ntawm anodic oxidation; Indirect oxidation yog hais txog kev tsim cov khoom nruab nrab uas muaj zog oxidizing los ntawm cov tshuaj tiv thaiv anodic lossis tshwm sim ntawm cov tshuaj tiv thaiv nruab nrab tshaj li cov tshuaj tiv thaiv anodic, uas ua rau oxidation ntawm cov pa phem kho thiab lawv qhov kawg hloov mus rau hauv cov khoom tsis zoo.
4. Electrodialysis txoj kev: nyob ntawm qhov tshwj xeeb muaj nuj nqi ntawm kev xaiv nkag mus rau hauv daim nyias nyias nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, ions tuaj yeem nkag los ntawm ib qho kev daws mus rau lwm qhov kom ua tiav qhov kev sib cais thiab kev sib cais ntawm cov pa phem ionized. Thaum electrodialysis dej siv los kho titanium anode hlau ions, cov hlau tsis tuaj yeem rov qab tau ncaj qha, tab sis cov tshuaj ntsev ntsev tuaj yeem tau txais, thiab cov dej ntws zoo tuaj yeem txhim kho tau zoo.
5. Electrochemical membrane sib cais txoj kev: Ib txoj kev sib cais uas siv qhov sib txawv ntawm ob sab ntawm daim nyias nyias, feem ntau siv rau kev sib cais ntawm cov pa phem.
3, Qhov zoo ntawm Electrochemical Water Treatment Technology
1. Cov hydroxyl radicals generated thaum lub sij hawm electrolysis txheej txheem ntawm titanium electrodes tuaj yeem ncaj qha cuam tshuam nrog cov pa phem hauv cov dej khib nyiab, degrading rau carbon dioxide, dej, thiab cov organic tebchaw yooj yim, tsis muaj los yog nrog cov pa phem me me. Nws yog ib puag ncig high-tech.
2. DSA can save energy (>23 feem pua) hauv kev lag luam chlor alkali nrog lub zog ua haujlwm siab. Cov txheej txheem electrochemical tuaj yeem nqa tawm ntawm qhov kub thiab txias.
3. Electrochemical txoj kev tuaj yeem siv ib leeg lossis ua ke nrog lwm txoj kev kho mob, xws li kev kho ua ntej, txhawm rau txhim kho biodegradability ntawm cov dej khib nyiab.
4. Cov khoom siv hluav taws xob thiab nws txoj haujlwm feem ntau yog qhov yooj yim thiab siv tau zoo.
