Titanium anode mesh thoob rau dej phwj kho
Kev kho dej khib nyiab thev naus laus zis suav nrog sedimentation, pom, flocculation, biodegradation, electrolytic oxidation thiab lwm txoj kev. Thaum kho cov dej khib nyiab los ntawm electrolysis, cov electrodes tsis tsuas yog ua lub luag haujlwm ntawm kev xa tawm tam sim no, tab sis kuj ua rau cov oxidation thiab degradation ntawm cov organic teeb meem, thiab yuav tsis ua rau cov pa phem thib ob. Nws yog hu ua ntsuab dej kho tshuab. Rau cov dej khib nyiab uas tsis tuaj yeem kho los ntawm biodegradation, electrolytic oxidation feem ntau muaj qhov cuam tshuam loj. Yog li ntawd, electrolytic dej kho tshuab tau dhau los ua kev tshawb fawb hotspot hauv kev kho dej thiab tau siv dav zuj zus. Lub hauv paus ntsiab lus ntawm electrolytic dej kho tshuab yog ua kom muaj kuab paug nyob rau hauv ncaj qha electrochemical tshua los yog indirect electrochemical transformations ntawm electrodes, uas yog, ncaj qha electrolysis los yog indirect electrolysis.
(1) Direct electrolysis Direct electrolysis yog hais txog kev tshem tawm cov pa phem ntawm cov dej khib nyiab los ntawm kev oxidation ncaj qha lossis txo cov electrodes. Direct electrolysis tuaj yeem muab faib ua cov txheej txheem anodic thiab txheej txheem cathodic. Cov txheej txheem anodic yog tias cov pa phem tau oxidized rau ntawm qhov chaw anode thiab hloov mus rau hauv cov tshuaj lom neeg tsawg lossis cov tshuaj biodegradable yooj yim, lossis txawm tias cov organic organic teeb meem, yog li ua tiav lub hom phiaj ntawm kev txo thiab tshem tawm cov pa phem. Cov txheej txheem cathode yog cov txheej txheem ntawm kev txo cov pa phem ntawm qhov chaw cathode thiab tshem tawm lawv. Nws yog tsuas yog siv rau kev txo qis thiab dehalogenation ntawm halogenated hydrocarbons thiab rov qab los ntawm cov hlau hnyav.
(2) Indirect electrolysis Indirect electrolysis yog hais txog kev siv cov tshuaj electrochemically generated redox raws li reactants lossis catalysts los hloov cov pa phem rau hauv cov tshuaj lom neeg tsawg. Indirect electrolysis muab faib ua reversible thiab irreversible txheej txheem. Cov txheej txheem thim rov qab (mediated electrochemical oxidation) xa mus rau electrochemical regeneration thiab recycling ntawm redox tshuaj thaum lub sij hawm electrolysis. Cov txheej txheem irreversible yog hais txog kev siv cov khoom tsim los ntawm cov tshuaj tiv thaiv tsis tau electrochemical, xws li oxidizing acid ntsev, subacids, H2O2 thiab O3, kom oxidize organic teeb meem. Cov tshuaj tiv thaiv hluav taws xob kuj tuaj yeem siv los ua kom muaj zog oxidizing intermediates, nrog rau cov hluav taws xob solvated, HO, HO2, O2- thiab lwm yam dawb radicals.
Cov cuab yeej tshiab ntawm electrolysis rau kev kho dej muaj qhov zoo ntawm qhov tsis tas yuav ntxiv cov tshuaj tua kab mob, cov khoom siv me me, cov hneev taw me me, thiab tsis muaj cov pa phem thib ob. Nws tau siv los kho cov dej khib nyiab uas muaj hydrocarbons, cawv, aldehydes, ethers, thiab lwm yam kuab paug organic. Kev tshem tawm ntawm COD feem ntau yog nyob ntawm cov tshuaj tiv thaiv oxidation ntawm qhov chaw anode, ncaj qha oxidizing thiab degrading organic teeb meem ntawm anode nto, kom cov organic teeb meem nyob rau hauv cov dej phwj tuaj ncaj qha los yog indirectly hloov mus rau hauv CO2 thiab dej los ntawm electrochemical conversion. Lub peev xwm anode yuav tsum siab tshaj qhov muaj peev xwm ntawm cov organic teeb meem, yog li ob qho kev sib tw ntawm cov organic oxidation thiab oxygen evolution yog nqa tawm ntawm lub anode. Cov duab ntawm cov anode muaj xws li phaj, raj, mesh thiab lwm yam ntaub ntawv rau cov neeg siv xaiv, thiab qhov zoo yog txhim khu kev qha. Cov titanium matrix tuaj yeem rov siv dua.
Daim ntawv thov ua tiav: electroplating wastewater, coking wastewater, organic wastewater, khib nyiab, luam ntawv thiab dyeing khib nyiab, khib nyiab pov tseg, fecal dej phwj, oily khib nyiab, dej khib nyiab, oilfield reinjection dej, hlau rov qab khib nyiab, dej phwj tuaj, catering wastewater kho, thiab lwm yam. txais yuav ntsuab ib puag ncig tiv thaiv. tshiab technology-electrocatalytic electrolysis.
