摘　　要：本文采用氯气作为氧化剂,对乙基氯化物生产废水进行氧化脱硫处理。其间以硫化物的去除率和单质硫的产量为考察指标,探究有效氯气通量、反应时间、反应温度和保温时间对反应的影响。结果表明,最佳条件为:有效氯气通量30 g,反应时间12 h,反应温度35℃,保温时间30 min。在最佳条件下,硫化物的浓度从31.41 g/L降至1.98 g/L,去除率可以达到93.68%,单质硫产量达到108 g/L。In this paper,chlorine gas is used as the oxidant to carry out the oxidative desulfurization treatment of ethyl chloride production wastewater.In the meantime,the sulfide removal rate and the output of elemental sulfur are used as the inspection indicators to explore the influence of the effective chlorine flux,reaction time,reaction temperature and holding time on the reaction.The results show that the best conditions are:effective chlorine flux 30 g,reaction time 12 h,reaction temperature 35℃,and holding time 30 min.Under the optimal conditions,the concentration of sulfide decreased from 31.41 g/Lto 1.98 g/L,the removal rate can reach 93.68%,and the elemental sulfur output reaches 108 g/L.
