摘　　要：对钼酸铵生产过程中产生的含钼酸性废水进行纳滤试验研究,目的是浓缩废水,提高废水中钼含量,便于回收金属钼。同时也简要介绍了纳滤技术分离原理。通过纳滤系统可将废水浓缩6倍以上,对钼和其他高价金属离子有较高的截留率,初步验证了纳滤系统对该废水处理的可行性。The effect of the nanofiltration on acid water containing molybdenum during the process of ammonium molybdate production was studied. The purpose is to concentrate waste water and increase the content of molybdenum in it for molybdenum extracting with ease. The separation mechanisms of nanofihration were also introduced. Through experiments, water can be concentrated over six times and the rejection rate of other muhivalent metal ions were high.
