摘要
选用合金滤料(KDF55)对自来水进行深度处理,以研究对水中铅、铬和镉的去除效果。试验结果表明,KDF55对水中重金属离子有较好的去除效果,在保证一定接触时间的条件下,对自来水中铅、铬和镉的去除率分别为77.9%、86.5%和70.1%。研究表明:KDF55对自来水中铅、铬和镉有稳定的去除效果。
Experiments were carried out to study the removal rate of lead,chromium and cadmium by KDF55 medium in drinking water advanced treatment.The results show that KDF55 has a good removal effect on heavy metals.In a certain detention time,the average removal rates of lead,chromium and cadmium were 77.9%,86.5%,and 70.1%,respectively.The removal effect of KDF55 on lead,chromium and cadmium in drinking water was stable.
