摘　　要：利用臭氧氧化法处理含硫皮革废水,研究了n(O3)∶n(S2-)、p H、反应时间对废水中S2-去除效果的影响。实验研究表明,臭氧氧化法可以有效去除废水中的S2-,且对COD也有一定的去除作用。在反应过程中n(O3)∶n(S2-)、p H、反应时间对S2-的去除率影响很大。在p H=7.5,n(O3)∶n(S2-)=0.5时,60 min时臭氧氧化法对S2-去除率可达96.24%。The ozonation process has been used for treating the leather wastewater containing sulfide. The influences of n （O3）：n （S2-）, pH and reaction time on S^2- removing effect are investigated. The results show that S2- could be removed effectively from wastewater by ozonation, and the COD can be removed to a certain degree, as well. In the process of reaction, n （O3）：n （S^2-）, pH, and reaction time have great influences on S^2- removing rate. The S^2- removing rate by ozonation method reaches 96.24% under the condit.
