Lub teeb pom kev photocatalysis yog dab tsi?
Pom kev pom kev photocatalysis yog hais txog photocatalytic oxidation thiab degradation ntawm photocatalyst nyob rau hauv cov xwm txheej pom kev.
Lub hauv paus ntsiab lus ntawm kev siv photocatalytic ntawm lub teeb pom kev zoo yog dab tsi?
Lub hauv paus ntsiab lus catalytic ntawm lub teeb pom kev yog raws li lub teeb pom kev irradiation lub teeb catalyst, catalyst valence band ntawm lub teeb av xeev electron hloov mus rau lub conduction band, tsim lub teeb yug los qhov thiab lub teeb hluav taws xob, lub teeb qhov nrog cov dej molecules los tsim hydroxyl dawb radicals, electrons thiab oxygen molecule reaction tsim super oxygen anion, thiab qhov, hydroxyl radicals thiab superoxide anion ntau lawm. Cov reactive oxygen hom tuaj yeem rhuav tshem cov ntxhiab tsw, cov organic matter, cov kab mob thiab lwm yam pa phem mus rau hauv dej thiab carbon dioxide thiab lwm yam me me molecules. Ib qho me me ntawm N, S thiab P hauv cov organic matter yuav tsim nitrate, sulfate, phosphate thiab lwm yam tom qab degradation, yog li ua si lub detoxification, deodorization thiab sterilization effect. Lub teeb pom kev photocatalytic txheej txheem muab cov kev daws teeb meem ntsuab tshiab rau kev kho cua sov sab hauv tsev thiab sab nraum zoov.
Vim li cas ho siv lub teeb pom kev zoo photocatalysis?
Raws li cov lus piav qhia hauv lub teb chaws tus qauv GB / T 17683.1-1999, lub teeb ultraviolet hauv lub hnub tsuas yog suav rau 7%, lub teeb pom kev zoo suav rau 71%, thiab infrared suav rau 22%. Txawm hais tias lub zog ntawm ultraviolet photon loj dua li ntawm lub teeb pom kev zoo lossis lub teeb infrared, lub teeb pom kev zoo thiab lub teeb infrared "yeej" los ntawm tus lej. Cov thev naus laus zis photocatalytic oxidation ib txwm muaj tsuas yog nyob rau hauv qhov kev ua ntawm lub teeb ultraviolet oxidation degradation ntawm cov organic pollutants. Thiab jiangyin hnub lub xeev quantum txheej technology co., LTD. Khoom ntawm lub teeb pom kev zoo catalytic oxidation technology khoom thiab quantum theem TiO2, nws txoj haujlwm tuaj yeem tshwm sim tsis yog tsuas yog nyob rau hauv lub teeb pom kev zoo photocatalytic oxidation degradation, tab sis kuj tuaj yeem catalytic oxidation degradation nyob rau hauv ultraviolet thiab infrared teeb reaction, nws yog ib qho tshiab spectrum teb ntawm photocatalytic technology, zoo heev txhim kho qhov ua tau zoo.
