Dyeing Waster Dej Kho Mob Daj Daj

Dyeing thiab luam tawm kev lag luam Waster Dej Kho, yog hais tias dej ntxuav tom qab biochemical kev kho, kev siv ferrous sulfate thiab kua caustic soda, yog vim li cas kev kho cov dej tom qab xim daj ntseg daj ntseg? Zoo li qhov tshwm sim no feem ntau yog vim li cas, hom kev dab tsi yuav tsum raug siv los nrog nws? Cov nram qab no nrog koj nyob rau ntawm luam tawm thiab dyeing Waster Dej Kho tom qab daj.

Kev Kho Dyeing Wastewater los ntawm Ferrous Sulfate

Kev luam tawm thiab dyeing wastewater yog ib qho hauv cov organic teeb meem cov ntsiab lus, xim tob, alkaline thiab li ntawm. Yog hais tias nws kho nrog ferrous sulfate thiab kua alkali tom qab yuav muaj daj muaj ob txoj hau kev, ib qho ntawm cov luam ntawv thiab dyeing wastewater tsis precipitated nyob rau hauv tej lub inorganic hlau ions, qhov thib ob yog xim ntawm cov organic teeb meem; Ntawm kev tshem tawm ntawm cov hlau hlau inorganic hlau yuav siv los kho lub alkali, Waster Dej Kho ntxiv sodium sulfide thiab thiaj li ua kom tsaug zog inorganic hlau ions. Yog tias cov organic teeb meem tam sim no nyob rau hauv lub luam ntawv thiab dyeing wastewater ua rau cov xim tshwm daj daj, nws yog qhov yuav tsum tau xav txog cov tshuaj oxidation los yog adsorption.

Rau cov xim thawj xim ntawm cov dej khib nyiab yog daj, nrog hlau ferrous tom qab xim xim ploj, thiab ces vim li cas rau qhov tshwm sim daj tuaj yeem kuj yog ib hom paj yeeb tshuaj, thiab kev siv thiab qee qhov reactive dyes ntsig txog rau pem hauv ntej kom pom cov xim tshem tawm, ua raws li los ntawm Thiab cov pov thawj qub dej zoo ib yam li cov xim, yog li feem ntau ntawm cov dyeing thiab luam ntawm Waster Dej Kho tus txheej txheem yuav yog kev kho biochemical.

Kev tiv thaiv tsis ntev dhau los nrog dyeing tsob nroj wastewater decolorization, kev siv ferrous, sodium hydroxide thiab poly txhuas tshuaj chloride, tom qab kev kho mob ib feem ntawm liab lossis tsis tuaj yeem raug muab tshem tawm, Lub Ntsuas Dej Tshuaj Paum 8, vim li cas cov liab tsis tuaj yeem tshem tawm, puas yuav xav txog qhov hloov ntawm lwm yam tshuaj? Ntawm no peb tau ua ib qho kev soj ntsuam raws li qhov teeb meem.

Tshuaj Ntsuab Phosphate Sulfate Dos thiab PH Phaus

Kev siv ferrous sulfate rau xim liab, ntsuab dej tshuaj kho nyhuv yuav mob heev, tab sis, ntev li qhov teeb meem uas tsim nyog muaj peev xwm feem ntau kuj yuav txo tau cov qauv ntawm cov xim. Hauv qhov no, cov tswv yim nram qab no yog ua:

1, sodium hydroxide ntxiv rau pem hauv ntej, rov qab ntxiv ferrous, ntxiv rau ntxiv tom qab tus PH nyob ntawm 9 los yog li ntawd. Tom qab ntxiv cov tshuaj sodium hydroxide, cov pH tuaj yeem ncav tau tshaj 12, nyob rau hauv cov kab mob uas muaj alkali muaj peev xwm rhuav tshem qee cov qauv ntawm cov xim dawb, nyuaj nyuaj nrog cov xim ntawm cov xim kom yooj yim nrog cov xim dawb. Thiab thaum pib ntawm cov tshuaj tiv thaiv nrog lub ferrous hlau PH yuav tsum yog 11 los yog li ntawd, qhov ferrous hlau nyob rau hauv tus nqi paug ntawm 11 los yog ntau dua decolorization effect yuav zoo dua lub pH ntawm 8 los yog li, Waster Dej Kho tshwj xeeb tshaj yog ib feem ntawm qhov nyuaj los mus nrog cov pab pawg xim dawb.

2, sodium hydroxide rau hauv cov kua qaub, thaum txo tus nqi ntawm pharmaceuticals kuj muaj cov nyom ntawm kev txhim kho cov kev kho mob.
