Cov yam ntxwv ntawm Kev Luam Ntawv Thiab Dyeing Khib Nyiab

Cov yam ntxwv ntawm luam ntawv thiab dyeing dej khib nyiab

Kev lag luam luam ntawv thiab dyeing kev lag luam yog kev lag luam loj muaj dej phwj tuaj yeem, dej phwj yog feem ntau muaj cov ntawv xov nyob rau ntawm cov av, roj, ntsev thiab ua ntawm ntau yam ntxiv slurry, dyes, surfactants, additives, acid thiab alkali, thiab lwm yam.

Kev siv dej khib nyiab yog qhov muaj qhov zoo ntawm cov teeb meem ntawm cov organic, kev sib xyaw ua ke, xim sib sib zog nqus thiab hloov pauv, loj pH pauv, dej loj thiab dej hloov pauv, nws nyuaj rau kev kho dej khib nyiab.

Nrog rau kev tsim cov tshuaj fiber ntau cov ntaub, qhov sawv ntawm emulation txhob lo lo ntxhuav thiab kev txhim kho ntawm luam ntawv thiab dyeing tiav, lub PVA slurry, rayon alkaline hydrolysis, dyes tshiab, kev pabcuam thiab refractory cov organic sib xyaw ua ntau yam ntawm textile printing thiab dyeing wastewater, ua rau muaj kev cov nyom loj rau cov txheej txheem dej khib nyiab ib txwm muaj, cov COD concentration kuj tau nce los ntawm thawj pua pua milligrams nyob rau ib zaug txog 3000 ~ 5000 mg / l.

Pulp dyeing khib dej dej siab chromaticity, siab COD, tshwj xeeb tshaj yog raws li kev lag luam txawv teb chaws tsim cov lo lo ntxhuav, txhob lo lo ntxhuav dub, tsaus xiav, xiav xiav, tsaus nti xws li luam ntawv thiab dyeing txheej txheem, cov xim sulfur yog siv dav hauv luam ntawv thiab dyeing, luam ntawv thiab dyeing cov koom haum xws li sodium sulfide, cov dej khib nyiab muaj ntau ntawm cov tshuaj sulfide, yog li no, cov dej khib nyiab no yuav tsum tau muab tshuaj ua ntej, thiab tom qab ntawd cov kev ua kom muaj peev xwm, tuaj yeem ruaj khov cov txheej txheem tawm.

Cov dej khib nyiab muaj cov tshuaj pleev xim dawb, sis plawv hniav, tus neeg sawv cev sab nraud thiab lwm cov koom haum, cov dej tsis huv no, qhov ntom ntom thiab chromaticity muaj tsawg, yog tias tsuas yog siv physico-tshuaj kho mob, cov dej cawv yog li ntawm 100 ~ 200 mg / l, xim kuj tuaj yeem ua rau ua tau raws li qhov xav tau emissions, tab sis kom muaj kev ua qias tuaj, tus nqi siab ntawm kev kho sludge, yooj yim ua rau muaj kev ua qias tuaj zaum ob, nyob rau hauv kev tiv thaiv ib puag ncig ntawm kev tiv thaiv ib puag ncig, kev siv tshuaj biochemical yuav tsum txiav txim siab, thiab cov txheej txheem kev txhim kho lom neeg tuaj yeem ua kom tau raws li qhov xav tau.
