摘　　要：根据铬鞣废水的特征及处理要求,提出了一种铬鞣废液的处理与循环利用新方法。该方法中所提取的大分子铬和处理后的废水都可重新利用。并基于这一思路描述了该方法中所采用的铬离子捕集剂的结构特征以及原料选择的基本原理。A new method to treat and recycle the chrome tanning waste water is presented in this paper according to the characteristic of effluent and the restriction of environment. With this method both of the treated waste water and chrome picked-up from the waste water can availably be reused. Based on this thought, characters of chrome binder and principle for selecting materials were briefly described in this paper.
