摘　　要：通过在电解金属锰渣中加入助剂,采取高温股烧和微波消解的方法活化SiO_2,利用正交试验和单因素试验研究得出了电解金属锰渣中有效硅活化的最佳质量配比为电解金属锰渣∶CaCO_3∶Na_2CO_3∶NaOH=1.00∶0.60∶0.15∶0.10,在此比例下经400℃高温股烧,其有效硅含量达到6.94%,用微波消解其有效硅含量达8.08%,同时水溶性锰含量达1.51%,枸溶性锰含量达5.01%。经活化后的电解金属锰渣可作为硅锰肥,为植物提供必要的生长元素。By adding additives in EMM slag, we know high temperature and burning method will take stock of microwave digestion SiO2 activation test of orthogonal test. Single factor was obtained by using the optimal ratio of the effective activation of silicon manganese slag in EMM slag： CaCO3： Na2CO3： NaOH = 1.00：0 60：0 15： 0.10. After burning to high temperature of 400 shares in this ratio, the effective silicon content will reach 6.94% with the microwave digestion in effective silicon content up to 8.08%. While water soluble manganese content reaches 1.51%, citrate soluble manganese content can reach 5. 01%. When EMM slag was activated as manganese fertilizer, it can bring about the necessary elements for plant growth.
