Cov txheej txheem tseem ceeb ntawm kev rho tawm kub siv cov txheej txheem slurry yog:
(1) Adsorption: Thaum cov tshuaj cyanide uas muaj kub dhau los ntawm kev sib pauv resin kem, ib qho kev sib pauv ion tshwm sim, thiab kub yog adsorbed ntawm cov resin.
(2) Desorption: Siv tus neeg sawv cev desorption los desorb kub ntawm cov resin rau hauv cov tshuaj. Rau cov tsis muaj zog alkaline kub loaded resins, desorption tuaj yeem nqa tawm ntawm chav tsev kub thiab siab siv cov tshuaj sodium hydroxide nrog pH =13; Rau muaj zog alkaline kub loaded resins, txoj kev sodium hypochlorite, acidic thiourea txoj kev, zinc cyanide complex txoj kev, thiab thiocyanide complex txoj kev yuav siv tau rau desorption.
(3) Kev rov qab kub: Kub tau rov qab los ntawm cov kev daws teeb meem desorption nplua nuj nyob rau hauv kub siv zinc hmoov hloov, alkaline nag lossis daus, los yog electrolysis txoj kev.
Qhov zoo ntawm ion txauv resin
1. Kev taw qhia kev xaiv thiab ua kom huv: tshwj xeeb kub absorbing resins muaj zog xaiv. Rau cov hlau hnyav hnyav, kev taw qhia adsorption thiab incineration tuaj yeem ua rau kub purity ntau dua 90%.
2. Cov txheej txheem yooj yim thiab kev ua tiav yog siab: Tom qab cov tailings khib nyiab tau kho nrog Kehai Si tshwj xeeb kub absorbing resin, cov ntsiab lus kub ntawm cov dej khib nyiab tuaj yeem ncav cuag hauv qab 0.02ppm, nrog rau kev ua haujlwm raug. Cov tailings tsis muaj kub, thiab tsis tas yuav purify lawv dua tom qab incineration. Cov txheej txheem yog yooj yim.
3. Loj adsorption muaj peev xwm txo cov nqi kho mob
