摘　　要：电子垃圾废水中由于含有大量的重金属离子,会对生态环境和人类健康产生严重危害。当前,传统处理含重金属离子的废水的方法大都存在一定的缺陷,比如,化学沉淀法产生大量的污泥,增加了处理难度和费用;吸附法中吸附剂价格昂贵,吸附容量有限且再生困难;膜法运行费用较高等。分析了电子垃圾废水的组成和危害,综述了当前处理电子垃圾废水的组合工艺,为电子垃圾废水处理技术的选择提供了依据,并对电子垃圾废水处理技术的发展趋势进行了展望。Electronic waste water, which contains large amounts of heavy metal ions, does serious harm to the ecological environment and human health.The traditional approaches have achieved good treatment effect, but there are some flaws. For example, chemical precipitation produces large amounts of sludge, which increase the difficulty and the cost of treatment; for adsorption, the adsorbent is expensive, and the adsorption capacity of adsorbent is limited and it is difficult for adsorbent to regenerate; as to membrane, which is more higher operating costs; and so on. This paper analyzed the composition and hazards of electronic waste water, introduced the current combined treatment technology of e-waste water, and provided a basis for selecting treatment technology of electronic waste water and the development trends of e-waste water treatment technology were prospected.
