| Abstract: |
The saturated SiC with the adsorption of Mn2+ was regenerated dynamically by water backwashing and NaOH, and the Mn2+ removing effect was compared by the two ways .The results showed that on the condition of Mn2+ concentration at 1.7～2.2 mg/L,flowing speed at 7.8 m/h, the regeneration rate of saturated SiC was only 49.8% after the first regenerated by backwashing .As for the second time,the rate was less than 15%,which had lost Mn2+ removing ability .But by NaOH, the regeneration rate was more than 100% after the fifth regenerated,which was obviously better than that of backwashing .And further study was conducted on Mn2+ removing mechanism by SiC through SEM figures. |
