Silicone ink wastewater tsis muaj tshuaj lom thiab tsis muaj mob, tab sis nws muaj cov yam ntxwv ntawm cov tshuaj muaj pes tsawg leeg, tshuaj lom neeg ruaj khov, insoluble hauv dej thiab lwm cov kuab tshuaj, thiab loj chromaticity. Txawv ntawm silica gel sib txawv muaj cov dej khib nyiab sib txawv vim muaj cov txheej txheem tsim khoom sib txawv, yog li cov txheej txheem kho kuj muaj qhov sib txawv.
Kev tso tawm ncaj qha yuav ua rau muaj kuab paug rau lub cev dej, cov dej loj hauv cov dej uas tau muab tshem tawm, yooj yim kom nqos tau ntses, ua rau tib neeg lub cev raug mob los ntawm cov zaub mov noj, ua kom muaj kev cuam tshuam, cuam tshuam cov duab hluav taws xob ntawm cov nroj tsuag hauv dej, rhuav tshem cov kev sib txig ntawm ecological.
Vim tias silicone number case dej khib nyiab muaj ntau ntawm cov kev txwv tsis pub siv, thiab nws tsis yooj yim kom yaj hauv dej, thiab nws cov biodegradability tsis zoo, feem ntau yuav tsum tau siv flocculation thiab lwm txoj kev tiv thaiv ua ntej kom tshem qee cov kev txwv tsis pub tawm, thiaj li txhim kho biodegradability ntawm cov dej khib nyiab thiab txo cov kev thauj tom qab.
Cov hau kev hauv qab no tuaj yeem siv rau yav tom ntej:
01
Lub cev txoj kevsuav nrog adsorption, tig, microfiltration, ultrafiltration, millimeter microwave thiab thim rov qab osmosis. Ntawm lawv, cov huab cua flotation yog siv dav hauv Suav teb.
02
Siv txuj ci tshuajsuav nrog hlau carbon micro electrolysis, oxidation-txo, coagulation nag lossis daus, photocatalytic oxidation thiab acid nag lossis daus. Ntawm lawv, cov pa roj carbon hlau micro electrolysis, coagulation nag lossis daus thiab kua qaub nag lossis daus yog cov txheej txheem tseem ceeb ntawm kev siv tshuaj silicone dej khib nyiab kho nyob hauv Suav teb.
03
Kev siv roj ntshasuav nrog hydrolysis acidification, ua kom cov txheej txheem sludge thiab lwm yam. Feem ntau ntawm cov kua roj silicone ua kua yog cov refractory cov organic sib txuas, uas nyuaj rau ua kom yoog tau los ntawm kev kho mob aerobic ib leeg, thiab cov nyhuv decolorization tsis zoo.
