Kev kho dej khib nyiab hauv kev lag luam textile siv hluav taws xob cua sov raj
Kev lag luam textile printing thiab dyeing wastewater kev lag luam yog ib qho kev lag luam nrog kev siv dej siab, cov ntsiab lus organic siab, thiab muaj kuab paug siab. Textile luam ntawv thiab dyeing cov dej khib nyiab feem ntau yog los ntawm cov txheej txheem xws li pulp (weaving) cov dej khib nyiab, refining cov dej khib nyiab, dej khib nyiab, mercerizing cov dej khib nyiab, dyeing khib nyiab, luam ntawv pov tseg, thiab cov dej khib nyiab tiav. Kev kho mob ntawm textile printing thiab dyeing cov dej khib nyiab yuav tsum ua ntej thiab foremost tsom rau kev tiv thaiv, nquag hloov cov txheej txheem ntau lawm thiab cov khoom siv, thiab txo qhov tsim cov khoom pov tseg thiab cov khoom pov tseg; Txo cov pa phem emissions thiab txhim kho cov dej rov qab siv dua los ntawm kev siv dej ntau dua thiab rov siv dua; Reusing dyeing thiab tshuaj raw cov ntaub ntawv tuaj yeem txo cov nqi tsim khoom thaum tseem txo cov pa phem ib puag ncig, ua rau ntau yam txiaj ntsig. Cov dej khib nyiab kawg yog tom qab ntawd kho thiab tawm mus.
Textile luam ntawv thiab dyeing cov dej khib nyiab muaj cov yam ntxwv ntawm cov dej khib nyiab loj, cov dej tsis zoo, thiab cov kev hloov loj ntawm cov dej zoo thiab ntau. Nws txoj kev kho mob yog qhov nyuaj, thiab nws feem ntau muab faib ua peb theem kev kho mob: qib thawj, qib thib ob, thiab qib thib peb. Kev kho thawj zaug feem ntau siv cov kab sib txuas, cov tso tsheb hlau luam ua ntej, lossis cov tso tsheb hlau luam thawj zaug, siv cov cuab yeej siv lub cev yooj yim lossis cov txheej txheem tshuaj los cais cov khib nyiab los yog cov blocks los ntawm cov dej khib nyiab, los yog kom tsis txhob muaj acidity thiab alkalinity ntawm cov dej khib nyiab. Kev kho mob thib ob feem ntau yog kev kho mob biochemical, uas tuaj yeem tshem tawm colloidal yaj cov organic kuab paug thiab txhim kho dej zoo. Thaum cov dej khib nyiab muaj biodegradability zoo, cov txheej txheem biochemical tuaj yeem xaiv tau; Thaum lub biodegradability ntawm cov dej khib nyiab tsis zoo, cov txheej txheem tshuaj xws li coagulation sedimentation lossis pressurized air flotation tuaj yeem xaiv. Kev kho mob qib thib peb feem ntau siv cov txheej txheem ntawm lub cev lossis tshuaj lom neeg los ua cov kev kho mob siab heev thiab ua tiav cov txheej txheem tso tawm lossis rov siv dua.
