摘　　要：以铬鞣废水为研究对象,通过沉淀、絮凝、纯化等处理方法,将铬鞣废水中高含量的铬回收为硫酸铬,使铬鞣废水达标排放。回收的硫酸铬纯度高,可作为铬鞣的化工原料,这是沉淀铬鞣废水行之有效的途径。Chromic sulfate was recovered from chrome tanning wastewater by precipitation, flocculation and purification. And tanning wastewater was exhausted below the primary standard （ 1.0 mg/L）. Purification of recoererd chromic sulfate was high and could be used as chemical materials. So it is a highly effective method for tanning wasterwatev treatment.
