Qhov nyuaj ntawm cov khoom siv dej khib nyiab hauv nroog yog qhov tshwj xeeb tshaj yog. Cov roj uas nqa los ntawm cov dej khib nyiab yuav tsim cov mis nyuj turbidity, cov ua npuas ncauj tsim los ntawm cov tshuaj ntxuav yuav tshwm sim xiav-ntsuab, thiab cov dej ntws ntawm cov khib nyiab feem ntau yog xim av tsaus. Lub kaw lus sib xyaw ntau xim no ua rau muaj kev xav tau ntau dua rau cov tshuaj tshem xim ntawm cov dej khib nyiab: nws yuav tsum muaj ntau yam haujlwm xws li demulsification, defoaming thiab oxidation-reduction tib lub sijhawm. Daim ntawv qhia kev sim ntawm lub chaw kho dej phwj hauv Nanjing qhia tau hais tias qhov sib txawv ntawm chromaticity fluctuation ntawm nws cov influent tuaj yeem ncav cuag 50-300 degrees, thiab qhov chromaticity ntawm cov effluent kho los ntawm cov tshuaj decolorizers wastewater ib txwm tseem nyuaj rau ruaj khov hauv qab 30 degrees.
Cov tshuaj ntxuav dej niaj hnub no tau ua tiav qhov kev ua tau zoo los ntawm kev tsim qauv molecular. Siv cov polymer hloov kho dicyandiamide-formaldehyde ua piv txwv, cov amine thiab hydroxyl pawg ntawm nws cov saw molecular tsim cov nyhuv synergistic: pawg amine ntes cov xim anionic los ntawm kev ua electrostatic, thiab pawg hydroxyl chelates nrog cov hlau ions kom tshem tawm cov xim hlau. Cov ntaub ntawv siv tiag tiag qhia tau tias tus nqi tshem tawm chromaticity ntawm cov dej khib nyiab hauv nroog tau nce mus txog ntau dua 92%, thiab tus nqi sedimentation ntawm alum flake tau nce txog li 25%. Qhov tseem ceeb tshaj plaws yog tias cov dej khib nyiab decolorizer no tseem tuaj yeem tswj tau qhov kev ua haujlwm siab hauv qab qhov kub qis.
Los ntawm qhov kev xav ntawm tag nrho cov txheej txheem kho dej, lub tshuab tshem xim dej khib nyiab tshiab coj ntau yam kev txhim kho. Hais txog kev kho kom zoo, tom qab lub Hoobkas dej rov qab siv lub tshuab tshem xim dej khib nyiab sib xyaw, lub sijhawm khaws cia ntawm lub tank sib tov ceev tau luv dua los ntawm 3 feeb mus rau 90 vib nas this; hais txog tus nqi ua haujlwm, tus nqi ntawm cov tshuaj lom neeg ib tuj dej tau txo qis li 18%, thiab cov zis sludge tau txo qis 15%; hais txog kev phooj ywg ib puag ncig, nws cov ntsiab lus monomer seem tau tswj qis dua 0.1 mg / L, uas qis dua tus qauv kev lag luam. Tshwj xeeb tshaj yog thaum kho cov dej khib nyiab sib xyaw ua ke, nws muaj peev xwm buffering zoo rau kev poob siab chromatic tam sim ntawd los ntawm nag hnyav scouring.
Kev tshawb fawb tam sim no tsom mus rau peb txoj hauv kev tshiab: cov tshuaj tua xim dej khib nyiab photocatalytic tuaj yeem lwj nws tus kheej tom qab kho kom tsis txhob muaj kuab paug thib ob; cov tshuaj tua xim dej khib nyiab uas teb tau rau qhov kub thiab txias tuaj yeem hloov kho cov qauv molecular raws li qhov kub ntawm dej; thiab bio-enhancedcov tshuaj tshem xim ntawm cov dej khib nyiab kev sib xyaw ua ke cov peev xwm ua rau cov kab mob puas tsuaj. Cov kev tsim kho tshiab no txuas ntxiv tsav tsheb kho cov dej khib nyiab hauv nroog mus rau qhov kev coj ua zoo dua thiab ntsuab dua.
