摘　　要：对制革含硫废水中的硫离子进行检测,并对其处理技术进行了研究。用对氨基二甲基苯胺光度法对S2-含量进行测定,采用酸化—吹取—吸收的预处理方法,同时用二次处理法,即絮凝和氧化相结合的方法,处理含硫废水,使处理后废水中S2-的去除率为99.998%,S2-浓度低于国家一级标准(1.0mg/L)排放。Technology of determination and disposing of sulfur in sulfur- contained tannery wastewater was studied. The pamino- N, N- dimethyl aniline spectrophotometric method was used to determine S^2- content, and the pretreatment of acidifi- cation - blowing extraction- absorption was applied, The combination method of flocculation and oxidation was used to retreat the wastewater. It shows that after treatment the sulfur removal rate of the wastewater is 99. 998 %, and the sulfur content is below the related national standard （ 1.0 mg/L）.
