硅碳素再生除锰效果试验研究

对硅碳素（ANJ．SIC）的再生及再生后去除水中Mn^2＋的效果进行试验研究。试验表明，用NaOH再生后的硅碳素（ANJ．SIC）与再生前相比，出水Mn^2＋浓度达到0．1mg／L以下的时间有所延长。当原水Mn^2＋浓度范围为2．162～2．24mg／L、流速为10．4m／h时，再生后硅碳素（ANJ．SIC）出水Mn^2＋浓度在0．1mg／L以下的时间比再生前延长了近1倍。对再生率进行了试验研究，得出再生次数与再生率的关系。试验表明，用NaOH再生后再生率在第二次时能达到182．3％，平均再生率为170％。对再生机理进行了深入的分析研究；

Study on the regeneration and regeneration rate of ANJ. SIC

The study of regeneration of ANJ.SIC and the effect of ANJ.SIC after regeneration to remove Mn2+ in the water.Tests show that comparison of ANJ.SIC which regeneration and before,the time of Mn2+ concentration in the water under 0.1mg/L.When the raw water concentration range 2.162～2.24mg/L,velocity range 10.4m/h,the time that Mn2+ concentration in the water under 0.1mg/L regeneration ANJ.SIC nearly double.The study of regeneration rate,the number of derived regeneration rate and regeneration.Tests show that after regeneration with NaOH,regeneration rate reached 182.3% in the second when the average renewable rate of 170%.The in-depth study and analysis of Regeneration mechanism.
