1. Heavy hlau khib nyiab
Cov yam ntxwv tseem ceeb:
Hom dej khib nyiab no feem ntau yog los ntawm cov txheej txheem kev lag luam xws li mining, hlau smelting, electroplating, tshuaj tua kab thiab chaw tsim tshuaj, xim, thiab xim ntau lawm. Nws lub ntsiab feature yog lub siab concentration ntawm ntau yam hlau ions, xws li tooj liab, zinc, chromium, cadmium, thiab txhuas. Cov hlau ions no muaj cov tshuaj lom neeg lom neeg tseem ceeb, nrog rau qib toxicity sib txawv ntawm cov hlau sib txawv; qee qhov ua rau muaj kev phom sij heev rau ecological ib puag ncig thiab tib neeg kev noj qab haus huv. Tsis tas li ntawd, ntau cov hlau hnyav ions zoo li tsim cov dej tsis huv hauv cov xwm txheej tshwj xeeb xws li qee qib pH.
Txoj kev kho mob:
Kev kho cov thev naus laus zis rau cov dej khib nyiab hnyav feem ntau yog nyob ntawm ob lub hauv paus ntsiab lus:
Chemical Transformation thiab Separation:Qhov no suav nrog kev hloov cov hlau hnyav hnyav rau hauv cov sib xyaw ua ke lossis cov qauv tsim los ntawm cov tshuaj lom neeg, ua raws li kev sib cais los ntawm nag lossis daus. Cov txheej txheem muaj xws li neutralization nag lossis daus, sulfide nag lossis daus, flotation sib cais, electrolytic nag lossis daus / flotation, thiab membrane electrolysis.
Physical Concentration thiab Recovery:Qhov no yog lub hom phiaj kom mloog zoo thiab cais cov dej khib nyiab yam tsis hloov cov tshuaj lom neeg ntawm cov hlau hnyav, uas tuaj yeem ua rau muaj peev xwm rov qab los. Cov txheej txheem muaj xws li rov qab osmosis, electrodialysis, evaporation concentration, thiab ion pauv.
Hauv kev xyaum, kev xaiv ntawm ib txoj hauv kev lossis kev sib xyaw ua ke yog nyob ntawm cov dej khib nyiab zoo, qhov ntau, thiab cov hom phiaj kev kho mob.
2. Metallurgical khib nyiab
Cov yam ntxwv tseem ceeb:
Cov dej khib nyiab los ntawm kev lag luam metallurgical yog tus cwj pwm los ntawm cov ntim loj, cov khoom sib xyaw ua ke, thiab kev hloov pauv loj hauv cov dej zoo. Raws li keeb kwm thiab qhov xwm txheej, nws tuaj yeem muab faib ua dej txias, dej khib nyiab, dej khib nyiab, slag flushing wastewater, coking wastewater, thiab dej khib nyiab los ntawm cov txheej txheem tsim khoom xws li condensates, kua cais tawm, thiab dej ntws tawm.
Txoj kev kho mob:
Kev kho cov dej khib nyiab metallurgical hais txog qhov txo qis thiab kev tswj hwm kev sib koom ua ke:
Txhawb Kev Tsim Nyog Cleaner:Kev tshawb nrhiav thiab siv cov dej tshiab-txuag, tsis yog- ua paug, lossis cov txheej txheem ua paug tsawg thiab cov thev naus laus zis, xws li coke qhuav quenching, thee preheating, thiab ncaj qha desulfurization thiab decyanation los ntawm coke cub gas.
Txhim kho cov ntaub ntawv rov qab:Tsim kom muaj kev siv thev naus laus zis kom rov qab tau cov ntaub ntawv tseem ceeb thiab thermal zog los ntawm cov dej khib nyiab thiab cov pa roj, txo cov peev txheej poob.
Txhim kho cov nqi rov ua dua dej:Kev siv cov kev npaj dej sib xyaw ua ke thiab kev siv cov cascading (ib ntus rov siv dua) raws li cov kev xav tau ntawm cov dej zoo ntawm cov txheej txheem sib txawv, nrog rau kev ntxiv dag zog rau cov dej stabilization cov txheej txheem kom nce cov dej rov ua dua tshiab.
Txhim kho cov cuab yeej siv tau zoo:Kev tsim kho tshiab cov txheej txheem kho kom haum rau cov yam ntxwv ntawm cov dej khib nyiab metallurgical. Piv txwv li, sib nqus sib nqus rau kev kho cov dej khib nyiab steel muaj qhov zoo xws li kev ua haujlwm siab, hneev taw me me, thiab kev ua haujlwm yooj yim.
