1. Kev xav
Cov pa roj carbon activated yog ua los ntawm cov ntoo, thee, txiv hmab txiv ntoo plhaub thiab lwm cov pa roj carbon monoxide- muaj cov tshuaj ua kom muaj zog hauv qhov kub thiab txias. Nws muaj ibtus lej lojntawm micropores thiab thaj chaw loj loj, feem ntau yog thaj tsam ntawm 1 gram ntawm cov pa roj carbon activatedtuaj yeem ncav cuag5001500 square metres, yog li nws muaj lub cev muaj zog adsorption muaj peev xwm, tuaj yeem nqus cov pa phem hauv cov dej pov tseg. Tsis tas li ntawd, qee cov pa oxygen- muaj cov pab pawg ua haujlwm, xws li carboxyl pawg (-COOH), hydroxyl pawg (-Oh) thiab carbonyl pawg, yog tsim los ntawm cov amorphous ntawm cov pa roj carbon activated. nto nyob rau hauv cov txheej txheem ua kom. Cov pab pawg no ua kom cov pa roj carbon activated muaj cov khoom siv tshuaj lom neeg adsorption, catalytic oxidation thiab txo qis, thiab tuaj yeem tshem tawm qee cov hlau ions los ntawm cov dej khib nyiab. Cov pa roj carbon activated muaj cov nyhuv adsorption muaj zog, tuaj yeem nqus cov khoom me me hauvindustrial dej khib nyiab,tshem tawm covnag lossis daus, kom ua tiav lub hom phiaj ntawm kev kho dej khib nyiab. Vim yog cov qauv ntxeem tau ntawm cov pa roj carbon activated, ntau qhov me me tau tsim rau ntawm nws qhov chaw. Txoj kab uas hla ntawm cov qhov no feem ntau yog nyob rau hauv ib tug me me nanometer kev txiav txim ntawm magnitude, uasuatuslojtxheeb ze thaj tsam ntawm activated carbon thiabloj adsorption ntawm nplua hais sab nraum.
Ntxiv nrog rau cov pa roj carbon activated rau hauv cov dej khib nyiab rau kev ywj pheej adsorption, kuj tseem tuaj yeem siv cov cua kub hauv cov txheej txheem adsorption rau cov pa roj carbon activated kom muab cov pa txuas ntxiv mus, kom lub peev xwm adsorption ntawm activated carbon hauv qhov cua thiab cua sov yuav maj mam ntxiv dag zog, nyhuv ntawmtusKev kho dej phwj yog pom tseeb dua.
2. Qhov zoo ntawm activated carbon adsorption rau kev kho dej khib nyiab
① Good thiab kuj ruaj khov kev kho mob nyhuv
② The resistance of microorganisms to organic poisons and heavy metals was improved;
③ Cohesive carbon bodies and microorganisms were produced to form solid and dense sludge, which improved the operating conditions of activated sludge process;
③ Activated carbon can adsorb surface active substances and solve the foam problem in the aeration tank
⑤ It can be used to treat wastewater with complex composition, variable concentration and water quantity;
⑥ Tsawgtus nqi ntawm hmoov carbon.
Cov pa roj carbon activated tuaj yeem tsis tsuas yog lub cev adsorb ntau yam tsis txaus ntseeg, tab sis kuj tseem siv tauly adsorb covteeb meem ions nyob rau hauv lub xeev ion. Nws muaj qhov zoo ntawm ob txoj kev kho lub cev thiab tshuaj. Ntxiv rau, nws efficiency thiab zoo nyob rau hauvkev kho cov dej khib nyiab muaj tshwj xeeb. Cov pa roj carbon activated muaj thaj tsam loj ntawm thaj chaw vim nws cov qauv ntxeem tau, uas ua rau nws muaj peev xwm adsorption siab. Nyob rau tib lub sijhawm, nws cov qauv carbon hlau ua rau nws nruj heev, uas ua rau cov pa roj carbon activated tswj nws cov duab thiab cov qauv hauv cov txheej txheem siv, thiab ua si lub luag haujlwm adsorption zoo.
Activated carbon adsorption method muaj qhov zoo ntawm txoj kev siv lub cev ua cov dej khib nyiab, tsis muaj mercury thiab chromium hauv cov dej khib nyiab ncaj qha rau ntawm cov hlau hnyav hlau ions thiab me me impurities xws li adsorption, ntxiv cov tshuaj ntxiv ntxiv, qhov no rau qee qhov, txo cov tus nqi ntawm kev kho dej khib nyiab hauv kev lag luam, thiab zam kev xau tshuaj chiv tuaj yeem ua rau puas tsuaj. Ntxiv nrog rau qhov zoo uas tau hais los saum toj no, tus nqi tsim khoom qis ntawm cov pa roj carbon activated kuj yog lub ntsiab lus tseem ceeb rau tib neeg xaiv nws los kho cov dej khib nyiab. Cov pa roj carbon activated los ntawm cov organic pov tseg hauv lub neej, thiab tom qab kev kho carbonization yooj yim thiab kev kho roj, nws dhau los ua cov pa roj carbon activated rau kev lag luam. Hauv cov txheej txheem ntawm kev kho cov dej khib nyiab nrog cov pa roj carbon activated, cov qauv thiab cov khoom ntawm cov pa roj carbon activated tsis tau hloov, uas ua rau nws muaj peev xwm rov ua dua cov pa roj carbon monoxide. Los ntawm kev ntxuav yooj yim nrog dej thiab ziab nrog xab npum, cov pa roj carbon activated tuaj yeem siv los kho cov dej khib nyiab dua. Txoj kev no ntawm kev kho dej khib nyiab nrog cov nqi qis thiab cov txiaj ntsig zoo tau siv los ntawmntau factories.
