摘　　要：简述了铬鞣废液的循环利用方法及其优缺点;提供了一种新的铬鞣废液有效回用于复鞣的工艺,复鞣废液Cr2O3含量低于0.1g/L,可直接排放,能实现铬鞣废液的封闭循环有效利用。In this paper the effective and cyclic utilization methods of chrome tanning waste-liquor and their advantages and disadvantages were described briefly. It was provided that a new cyclic utilization technique, which chrome tanning waste-liquor was used in retanning process, the chromium content （Cr2O3） of retanning waste-liquor would be lower than 0.1 g/L. Therefore, the retanning waste-liquor could be discharged directly and the closed effective and cyclic utilization of chrome tanning waste-liquor was realized.
