Feem ntau cov kab ntau lawm pleev xim muaj qhov zoo sib xws, uas yog ntau yam pov tseg raug tsim tawm thaum lub sijhawm pleev xim. Yog tias tsis muab pov tseg kom zoo, nws tuaj yeem ua rau muaj kuab paug rau ib puag ncig ib puag ncig. Txhawm rau tiv thaiv cov txiaj ntsig zoo li no, cov khoom pov tseg los ntawm cov kab ntau lawm muaj cov txheej txheem kev kho mob, kom daim ntawv thov ntawm cov kab ntau lawm kuj tuaj yeem ua tiav kev tiv thaiv ntsuab thiab ib puag ncig.
1. Hom khib nyiab tsim nyob rau hauv cov kab ntau lawm painting
Thaum lub sij hawm painting txheej txheem, ntxiv rau cov khoom khib nyiab, tseem muaj cov khib nyiab pov tseg, dej khib nyiab, suab nrov, thiab lwm yam, tag nrho cov no yog cais raws li cov khoom pov tseg. Vim tias cov yam ntxwv ntawm txhua hom khib nyiab sib txawv, cov kev kho mob kuj sib txawv.
2. Txoj kev kho cov pa pa hauv cov kab ntau lawm
Nyob rau hauv cov painting ntau lawm kab, pa pa gases yog emissions los ntawm ntau yam txheej txheem xws li pre-kho, pleev xim rau chav tsev, leveling chav, thiab ziab rauv. Txhawm rau kho cov pa phem los ntawm kev tso pa tawm, ntawm ib sab, yog tias cov coatings uas muaj cov kuab tshuaj organic tsis tuaj yeem siv, thiab ntawm qhov tod tes, siab concentration organic solvent pa gases tau sau thiab kho, cov txheej txheem ntxaws suav nrog incineration, catalytic incineration. , adsorption, thiab lwm yam.
3. Keeb kwm thiab kev kho cov dej khib nyiab hauv cov kab ntau lawm
Cov dej khib nyiab kuj yog los ntawm kev kho ua ntej hauv cov kab ntau lawm. Txoj kev dav dav yog sau tag nrho cov dej khib nyiab hauv qab daus thiab tswj nws raws li hom dej khib nyiab. Piv txwv li, dej yuav tsum neutralized, tso, lim, thiab tso tawm rau acidic thiab alkaline khib nyiab; Cov dej khib nyiab uas muaj chromium yuav tsum tau kho nrog cov txheej txheem xws li electrolysis thiab tshuaj txo kom tshem tawm cov teeb meem.
4. Cov txheej txheem kho cov khib nyiab pov tseg hauv cov kab ntau lawm painting
Cov khib nyiab pov tseg ntawm no yog tsim los ntawm cov xim residue thiab sediment generated tom qab kev kho dej khib nyiab. Nws tuaj yeem ua kom lub cev qhuav dej siv lub phaj thiab cov ncej lim xovxwm ua ntej, thiab tom qab ntawd thauj mus rau qhov chaw tshwj xeeb rau khaws cov khib nyiab pov tseg.
