摘　　要：介绍了铜锌合金滤料KDF55的作用原理,采用KDF55金属滤料去除水中金属铬,进行了一系列实验,测定了不同原水浓度、滤速、填充料高度下金属镉的去除率。通过KDF55对水中金属铬去除情况实验研究表明:KDF55对铬的去除效果非常明显,去除后的离子浓度远低于《生活饮用水卫生标准》。铬的去除率达到75%以上。This paper introduces the principle of copper-zinc alloy filter material KDF,KDF metal filter material was used to remove metal chrome from water,A series of experiments were carried out to determine the removal rate of metal chrome under different raw water concentration,filtration rate and filling material height.The experimental study on the removal of metal chrome from water by KDF55 shows that:The removal effect of KDF55 on cadmium is very obvious,and the ion concentration after removal is much lower than that of"Sanitary Standards for Drinking Water".The removal rate of chrome reached more than 75%.
