摘　　要：考察了KDF55、石英砂、沸石、椰壳活性炭联用对饮用水的净化效果。结果表明,系统对浊度的去除主要发生在椰壳活性炭滤层;对铜、铬、铅等重金属离子的去除主要由KDF55滤层完成,去除率均可达80%以上;系统还可明显降低饮用水的硬度和CODMn。该系统在有效去除污染物的同时,又可向水中释放微量对人体有益的锌离子,对家用净水机的开发具有重要的参考价值。The purification of drinking water by KDF55/coconut shell activated carbon/quartz sand/zeolite was investigated. The results show that the removal of turbidity is achieved mainly in the filter layer of coconut shell activated carbon. The removal of heavy metal ions such as copper, chromium and lead is achieved mainly in the filter layer of KDF55, and their removal rates are more than 80%. The system can also decrease the hardness and CODMn of drinking water. In addition to removing contaminants, the system can release beneficial trace zinc ions into the drinking water. It serves as a reference to the development of household water purification machines.
