摘要
本文对应用水玻璃和硝石灰在絮凝过程中形成硅酸及其盐的特性作了分析,对水玻璃—硝石灰沉淀法处理电解锰废水的最佳条件进行了研究,与常规硝石灰沉淀法比较,结果表明,水玻璃—硝石灰沉淀法保持了常规硝石灰沉淀法的优点,克服了其缺点.
This paper presents an analysis of the characteristics of the formation of silicic acid and silicate in flocculation process, an investigation of the treatment on electrolytic manganese waste water, a comparison between the new method and conventional calcium hydroxide precipitation. The results shows that the new method of sodium silicate-calcium hydroxide precipitation has kept the advantages of calcium hydroxide precipitation, and has given up all it's short-comings.
