摘要
本文在铁酸盐法(Ferrite)处理重金属离子废水的研究基础上,分别对铁酸盐渣、中和沉淀的氢氧化物渣和氟化钙沉淀渣上进行了铁酸盐包复膜的系统的实验研究。实验结果表明经过包复之后,三种渣在弱酸性介质中的稳定性明显增加,效果相当明显。产物可作为磁性材料使用。
Based on the Ferrite method for treating heavy metal wastewater,asystematic experimental study of ferrite coating membrane of ferrite sludge,neutralized precipitation sludge and calcium flouride sludge was done.Theresults of the experiment showed that the stability of those sludges wereenhanced in weak acidic solution,and the products formed can be used asmagnetic materials.
