Cov Ntawv Luam Ntawv thiab Dyeing Cov Khoom Siv Khib Dejyog tsuas yog tsim thiab tsim tawm rau luam ntawv thiab dyeing wastewater nrog kev daws teeb meem zoo hauv kev luam tawm thiab cov zas dej khov kho. Kev luam tawm thiab dye dej khib nyiab tuaj yeem tso tawm rau cov qauv tom qab kev kho mob.
Cov dej ua tau zoo ntawm cov tshuab luam ntawv thiab cov dej ntws ntxeem tau nyob ntawm seb cov fiber ntau siv thiab ua thev naus laus zis, thiab cov kuab huv, thiab cov kuab paug, thiab cov kuab huv si sib txawv. Luam Ntawv thiab Dyeing Wastewater feem ntau muaj cov yam ntxwv ntawm cov kuab paug siab, ntau hom, tshuaj lom thiab muaj zog chromaticity. Feem ntau, tus nqi ntawm luam ntawv thiab tawg ntho dej khib nyiab yog 6-10-400mg / l, ss yog 100-400mg / l, thiab lub chromaticity yog 100-400 zaug.
Tab sis thaum lub tshuab luam ntawv thiab dyeing txheej txheem, cov hom fibers siv, thiab kev hloov thev naus laus zis, cov dej phwj tuaj zoo yuav muaj kev hloov pauv tseem ceeb. Nyob rau hauv xyoo tsis ntev los no, vim muaj kev txhim kho cov tshuaj lom neeg fiber ntau, thiab kev nce qib ntawm cov duab nplaum (Alkali Hork) Lub codcr kev zoo kuj tau nce los ntawm ntau pua mg / u rau ntau tshaj 2000-3000mg / L, thiab tus lej pH tau nce mus txog 1100m / L, thiab ib puag ncig 50%, lossis txawm qis dua.
Tus nqi ntawm kev desizing rau luam tawm hauv kev luam ntawv thiab tawg ntaub nteg me me, uas muaj ntau qhov chaw ua qias tuaj, fiber ntau daim hmoov nplej, thiab ntau yam ntxiv. Cov dej phwj yog alkaline nrog pH nqi ntawm ib ncig 12. Lub ntsiab lus tseem ceeb li cov ntaub qhwv uas tseem ceeb thiab lub cev siab thiab cov txiaj ntsig biodegradability. Cov dej cawv uas tsim nyog nrog polyvinyl cawv (PVA) raws li lub ntsiab sizes sizing warn
Luam Ntawv thiab Dyeing Wastewater muaj ntau ntau ntawm boiling dej khib nyiab thiab cov roj citractans, thiab lwm yam dej khov kho, muaj dej ntas yeej kub thiab cov xim av.
Luam Ntawv thiab Dyeing Wastewater muaj ntau npaum li cas ntawm cov tshuaj lom neeg kom loj, tab sis cov pa ua pa tsw qab, uas muaj cov tshuaj tsw qab, uas muaj cov tshuaj txhuam hniav ntxiv, oxalic acid, sodium thiosulfate, thiab lwm yam.
Luam Ntawv thiab Dyeing Wastewater Mercerizing Wastewater muaj cov ntsiab lus alkali muaj siab, nrog Naoh cov ntsiab lus txij li 3% mus rau 5%. Feem ntau cov luam ntawv thiab zas ntoo rov qab naoh los ntawm evaporation thiab concertration, yog li mererizing pov tseg feem ntau tsis tshua tau tso tawm. Tom qab siv dua, qhov kawg tso tawm kom tshem tawm cov dej khib nyiab tseem yog alkaline tseem muaj txiaj ntsig, nrog lub cev siab, COD, thiab SS.
Tus nqi ntawm dyeing wastewaterater hauv kev luam ntawv thiab tawg yog tus loj, thiab cov dej tsis zoo sib txawv raws li cov dyes siv. Nws muaj slurries, dyes, ntxiv, steritives, surfactants, thiab lwm yam, thiab feem ntau muaj zog alkaline nrog cov chromaticity. Tus lej yog ntau dua li lub cev, thiab nws cov biodegradarability yog neeg pluag.
Tus nqi ntawm luam ntawv thiab tawg ntaub ntauv loj yog tus loj. Ntxiv nrog rau cov dej khib nyiab los ntawm cov txheej txheem luam ntawv, nws tseem suav nrog xab npum thiab dej ntxuav kom huv tom qab luam ntawv. Kev hais txog cov pa phem siab, suav nrog slurry, dyes, ntxiv, thiab lwm yam thiab cod yog txhua qhov siab.
Tus nqi ntawm cov dej khib nyiab los ntawm kev luam tawm thiab rab phom dej kom huv yog qhov me me, cov khoom siv fiber ntau, cov roj muag, thiab slurries.
Luam Ntawv thiab Dyeing Wastewater alkali txo cov txheej txheem txheej txheej alkali txo cov txheej txheem polyester thiab ua kom muaj zog polyesteric acid thiab cov ntsiab lus sib txawv Alkaline txo cov dej khib nyiab tsis yog muaj tus nqi pay siab (feem ntau> (feem ntau>, tab sis kuj tseem muaj qhov siab ntawm cov organic. Tus codcr hauv cov dej khib nyiab pov tseg los ntawm cov txheej txheem alkali txo tau mus txog 90000 mg / l. High molecular organic tebchaw thiab qee qhov dyes yog qhov nyuaj rau biodegrade, thiab hom wastewater belongs rau siab siab thiab nyuaj rau kev ua haujlwm organic wastewater.
Kev Luam Ntawv thiab Dyeing Wastewater Kho Khoom Siv Lub Neej Kev Ua Haujlwm ntawm Anaerobic thiab Aerobic Bulutants hauv cov pa dej huv. Nyob rau tib lub sijhawm, cov roj ntsha flocculents tsim los ntawm cov microorganisms ua kom muaj kuab paug, tsis muaj teeb meem ntawm cov txiaj ntsig orge, thiab thaum kawg ua tiav cov nyhuv ntawm purifywater.
Cov cuab yeej siv tau nruab nrog underwater aberation, uas yog thawb los ntawm dej ntws los ua me ntsis kev ua haujlwm. Thaum kho cov dej phwj tuaj rau hauv thaj chaw aeration los ntawm sab saum toj ntawm lub ntaus ntawv, thiab tus aerator undergoes undergoes undergoes underge dej igner thiab thawb cov ntws mus rhaub cov dej phwj. Cov dej phwj tuaj ua ke sai sai nrog cov sib xyaw ua ke tas mus li, hloov mus rau cov kev hloov pauv hauv cov kua dej zoo rau qhov ntau tshaj plaws. Tus aerator muaj cov dej ntws me me ntawm cov dej ntws tawm thiab unreewing cov dej phwj tuaj rau hauv cheeb tsam mus ncig ua si thiab nce cov ntsiab lus pa oxygen hauv cov dej phwj. Vim yog cov dej phwj mus txuas ntxiv thiab ntws ntawm thaj tsam ntawm thaj chaw, cov dej ua tau zoo ntawm txhua qhov chaw nyob hauv thaj tsam yog tus lej thiab cov khoom ntawm cov microorganisms zoo ib yam. Yog li ntawd, kev ua haujlwm ntawm txhua qhov ntawm lub aeration cheeb tsam yog yuav luag txhua yam. Qhov no yog tag nrho cov tshuaj tiv thaiv tag nrho biochemical nyob rau hauv kev ua zoo thiab zoo ib yam. Organic teeb meem yog maj degraded los ntawm cov kab mob me, thiab cov dej khib nyiab yog huv. Kev ua kom huv siab yog siab, thiab txhua qhov ntsuas ntawm effluent ntsib cov neeg muaj kuab paug hauv lub tebchaws Textile thiab kev lag luam tiav "(GB 4267-92). Raws li cov neeg siv khoom, txhawb cov qauv ntxiv rau cov qauv dej "(GB / T 18921-2002) rau kev rov ua dua tshiab thiab siv tau ntawm kev ua khoom siv:
Qhov kev sib xyaw ua ke no thiab dyeing cov khoom siv wastewater, wasing fastewater, ntaub ntawv fastewater, silk dyeing thiab xaus cov ntaub ntawv dyog thiab ua kom zoo nkauj thiab cov paj rwb fastewater, wove wastewater, wove rwb luam ntawv thiab cov paj rwb fastewater, woven rwb luam ntawv thiab cov paj rwb tshuab ntaub ntaub thiab ua kom zoo.
