摘要
吸附剂是水处理技术的一种重要手段。本研究在现有吸附剂的基础上用一种常见经济价值甚微的树皮做为原料进行了吸附剂的研制，对几种类型的吸附剂进行了不同填柱实验；不同类型吸附剂混合比的填柱实验；吸附剂的再生及再生后吸附剂吸附能力的实验研究。实验研究结果表明：此种吸附剂吸附吝量较大，再生容易，再生后的吸附剂吸附效果不受影响，并且吸附性能较为广泛。尤其对一些重金属元素有独持的吸附效果。此种类型的吸附剂原料来源广泛，价格低廉，制作简单。
Adsorbent is an important method in water treatment techology. Without an adsorbent,we have prepared a new adsorbens using a sort of newmaterialand also have done packed column experiments of different adsorbents,absorption experiments of different absorbent mixing ratios and experimentalstudy on revive method of adsorbent and its adsorption capacity. The resultindicates that this sort of new adsorbent has relatively large capacity,and iseasily to revile without influencing its effect and has relatively widerangeadsorption properties special for some heavy metals uniqtie adsorption effect. This new adsorbent has wide- range raw material sources, low prices andsimply production processes。
