Cov kuab tshuaj pov tseg (xws li PR, NMP, PMA, thiab lwm yam) uas tsim los ntawm cov xim, inks, textile dyes, thiab textile oils yog tsim los ntawm cov khoom siv kho dua tshiab hauv qee cov txheej txheem kom tau txais cov khoom hnyav. Cov khoom no yog siv los ua cov kuab tshuaj rau inks, xim, inks, textile dyes, thiab textile oils, nrog rau cov tshuaj ntxuav hauv kev tsim cov kua siv lead ua kua.
Qhia txog kev siv tshuab thiab khoom siv ntawm Ogano Tuam Txhab, ib lub tuam txhab Japanese npe nrog ntau tshaj 70 xyoo kev paub hauv kev kho dej, los ntawm kev siv cov kua qaub-base neutralization, chemical los nag, Fenton oxidation, pressurized air flotation, anaerobic hydrolysis, thiab IC sab hauv. Cov tshuaj tiv thaiv anaerobic Oxygen, tiv tauj oxidation, activated carbon adsorption thiab lwm yam kev kho dej khib nyiab ua ke ua rau lub tuam txhab muaj peev xwm ua tiav cov khoom siv, thev naus laus zis thiab kev txawj ntse los rov ua dua thiab kho cov kua dej muaj kuab paug siab, fluorine-muaj cov kua dej pov tseg, cov kua qaub pov tseg. thiab pov tseg alkali, tooj liab-muaj kua khib nyiab thiab lwm yam dej khib nyiab thiab dej khib nyiab hauv tsev. Lub peev xwm ua txhua hnub ntawm ntau yam kua khib nyiab tuaj yeem ncav cuag ntau dua 100 tons. Cov dej kho tau rov qab tuaj yeem rov siv dua li cov dej yaug hauv qhov chaw tsim khoom thiab kev cog qoob loo ntawm thaj chaw Hoobkas, ua tiav cov peev txheej ua haujlwm. siv.
