RO dej kho qhov system rau luam ntawv thiab dyeing dej khib nyiab
Tso lus
Kev luam ntawv thiab dyeing textile khib nyiab tsis tsuas yog muaj cov chroma siab thiab cov dej loj, tab sis kuj muaj cov khoom siv ntau heev. Cov dej khib nyiab muaj cov dyes, sizing agents, oil agents, auxiliaries, acid thiab alkali, fiber impurities thiab inorganic salts, thiab lwm yam. Cov qauv dye kuj muaj ntau yam lom lom lom lom. Xws li cov tshuaj, xws li nitro thiab amine tebchaw thiab cov hlau hnyav xws li tooj liab, chromium, zinc, arsenic, thiab lwm yam, yuav ua rau muaj kuab paug rau ib puag ncig yog tias lawv raug tso tawm ncaj qha yam tsis muaj kev kho mob.
Zenghangcheng siv ultrafiltration ntxiv rau RO ob chav membrane tshuab los kho luam ntawv thiab dyeing dej khib nyiab. Ultrafiltration tuaj yeem tshem tawm macromolecular organic teeb meem hauv cov dej khib nyiab, txo cov turbidity, thiab ua kom cov dej muaj txiaj ntsig zoo raws li cov cai ntawm RO membrane. Tom qab RO kho, tus nqi tshem tawm ntawm cov organic teeb meem thiab ntsev Nws tuaj yeem ncav cuag ntau dua 99 feem pua thiab 93 feem pua. Cov tshuaj oxygen xav tau ntawm cov dej tsim tawm tsawg dua 10mg·L-1, thiab hluav taws xob conductivity tsawg dua 80μS·cm-1. Cov dej ua tau raws li cov qauv dej rau feem ntau cov txheej txheem luam ntawv thiab dyeing. Zhong Jing siv hollow fiber ultrafiltration membrane thiab RO thev naus laus zis los kho cov ntaub plaub thiab dyeing cov dej khib nyiab. Nyob rau hauv cov xwm txheej ntawm kev khiav hauj lwm siab ntawm 0.1MPa thiab ntws tus nqi ntawm 1500Lh-1, cov ntsuas xws li chromaticity thiab ntsev cov ntsiab lus tau txo qis. COD tus nqi, Lub chromaticity ua tau raws li cov qauv emission.
