摘　　要：皮革含铬废水主要来自于铬鞣、复鞣等工序。在这些工艺中,铬的利用率较低,而且铬本身具有毒性,因此加强废水处理并回收铬资源十分必要。皮革含铬废水回收和利用的方法很多,本文主要介绍了皮革含铬废水处理的常用方法以及近年来兴起的新工艺技术,分析了各类技术中的优缺点和存在的问题,并探讨了铬资源的回收再利用问题。In leather industry, chromium - containing wastewater mainly came from the chrome tanning process and re - tanning process. In those processes, it was necessary for wastewater treatment and chromium recovery because of the toxicity and the low utilization of chromium. There were many treating and recycling techniques used for the chromium - containing wastewater, the treatment and recovery technologies of tannery wastewater containing chromium as well as their advantages and disadvantages were reviewed.
