Roj hmab vulcanization accelerator DPG wastewater kho hom. Ua ntej, cov dej khib nyiab yuav raug rau cov kua qaub-base, thiab cov khoom siv dej lim tau nkag mus rau hauv lub tshuab electrolytic uas muaj cov kua roj electrolytic ntawm 60-80 ° C, micro-electrolysis rau 2 mus rau 5 teev, tom qab ntsuas lub tshuab hluav taws xob lim, thiab cov khoom siv dej lim tau ntxiv nrog 10% mus rau 30 ml ntawm hydrogen peroxide / L wastewater rau lub concentration ntawm 30% hydrogen peroxide, muab kho rau pH = 2 mus rau 4, kho 2 mus rau 5 xuab moos, thiab tom qab ntawd ntxiv rau flocculation ntawm ib qho ntawm 200 mus rau 500 mg / L ntawm wastewater. Tus neeg sawv cev PAC yog flocculated, lub pH raug kho rau 8 mus rau 10, thiab lub sij hawm qias neeg yog 1 mus rau 2 xuab moos. Tom qab tso tshuaj pleev xim, nws lim dej ua ntej, thiab cov khoom siv dej lim dej yog adsorbed los ntawm activated carbon thiab reag, thiab tshem tawm ntawm CODcr nce mus txog 98%, ua kom tiav cov txheej txheem tawm. Txoj kev muaj cov txheej txheem yooj yim, cov cuab yeej tsis tshua muaj nqis, kev siv zog tsawg, kev tshem tawm high COD, tuaj yeem siab tshaj 98%, zoo dua cov kev kho mob, raws li cov txheej txheem emission, thiab yog yooj yim industrialize.

Tus neeg dag zog DPG yog tus ceev ceev nruab nrab ntawm kev rubber, qhov nruab nrab ceev accelerator rau roj hmab thiab hluavtaws hluavtaws, thiab tus activator rau thiazoles, thiurams thiab sulfenamide accelerators. Cov khoom tau ua tau zoo rau kev laus. Nws tsuas yog siv los ua cov khoom siv roj hmab xws li lub log tsheb, roj hmab xees thiab cov laug. Thaum lub sij hawm muaj kev khiav ntawm DPG accelerator, muaj ntau npaum cov concentration ntsev-muaj organic wastewater tsim, uas nyuaj nyuaj, thiab nws cov khoom thiab kev loj hlob zoo heev vim muaj kev siab ceev. Cov dej khib nyiab hauv DPG cov khoom tsim los ntawm niam txiv cov dej cawv distillation thiab dej ntxuav. Cov ntsev thiab COD ntau yog siab, nrog rau xim thiab tsw, thiab dej muaj ntau hom heterocyclic organic compounds, uas yog ib qho nyuaj rau kev kho mob los ntawm txoj kev biochemical. Tam sim no, muaj ntau cov ntawv qhia txog kev kho hom dej khib nyiab no, feem ntau evaporative distillation thiab lwm cov txheej txheem, uas muaj lub zog loj thiab kev kho pluag kho.

Cov dej khib nyiab hauv DB dej tshuaj tiv thaiv DPG cov tshuaj tua kab mob: ua ntej, cov dej khib nyiab yog ua rau cov kua qaub tsim kua qaub, thiab cov khoom siv dej lim tau nkag mus rau hauv lub tshuab electrolytic uas muaj lub tshuab hluav taws xob thiab electrolytic filters, thiab cov dej khib nyiab ntxiv nrog hydrogen peroxide rau Fenton oxidation, tom qab oxidation. Lub wastewater yog flocculated, sedimented thiab lim. Cov khoom siv dej lim dej yog cov adsorbed los ntawm activated carbon thiab cov tshuaj ntsuab, thiab kev tshem tawm ntawm CODcr nce mus txog 98%, kom tiav cov txheej txheem tawm.

Kev siv cov dej khib nyiab uas yog DPG wastewater txoj kev kho, cov dej khib nyiab yog ua rau cov kua qaub-base, thiab cov khoom siv dej lim tau nkag mus rau hauv lub tshuab electrolytic uas muaj cov kua roj electrolytic ntawm 60-80 ° C, micro-electrolysis rau 2 mus rau 5 teev, thiab cov dej khib nyiab tom qab cov tshuab hluav taws xob hauv tshuab hluav taws xob tawm. Filtration, ntxiv rau 10 mus rau 30 ml ntawm hydrogen peroxide ib lim ntawm cov dej tshuaj lim, ntxiv hydrogen peroxide nrog cov concentration ntawm 30% hydrogen peroxide, kho pH = 2 mus rau 4, kho rau 2 rau 5 teev, thiab tom qab ntawd ntxiv cov PFC flocculant PAC ntawm 200 mus rau 500 mg / L ntawm wastewater. Flocculation, pH kev hloov 8 ~ 10, lub sij hawm nyob yog 1-2 teev; lim tom qab txo qoob loo, cov khoom siv dej lim dej yog adsorbed los ntawm activated carbon thiab cov ntxaib, thiab tshem tus nqi ntawm CODcr yog tshaj 98%.
