摘　　要：采用石灰预处理法对皮革废水进行处理,研究了石灰添加量对灰皮水及蓝皮水COD值和氨氮含量的影响,结果表明:石灰预处理灰皮水可大幅度降低水体的COD值和氨氮含量,其原理应为可溶性蛋白质在等电点下沉淀,氨氮以氨气的形式挥发.This paper reports the performances of lime pretreatment methods for the treatment of tannery wastewater. The influence of lime addition on COD and ammonia-nitrogen content were researched. The results demonstrated significant removal of COD and ammonia-nitrogen of gray leather water.It was probably because that soluble protein would precipitate in isoelectric point,and ammonia nitrogen would volatilize in the form of ammonia.
