摘　　要：应用厌氧附着生长反应器对富含硫酸盐和有机物的废水进行预处理,以利于后续脱硫反硝化工艺的运行。当进水pH值为7.5时,硫酸盐和有机物的去除分别可达91.5%和90.5%,硫化物生成率可达47.8%。当HRT在7.7 h时,硫酸盐去除率高达95.79%,有机碳去除率为80%左右,硫化物生成率可达58.82%。结果表明,利于后续脱硫反硝化工艺的硫酸盐还原预处理条件为:HRT为7.7~10.2 h,进水pH为7.5~8。An anaerobic attached-growth bioreactor was set up to treat wastewater rich in sulfate and organic carbon.It was the pretreatment of desulfurization-denitrification process.When pH value was maintained at 7.5,the removal rates of sulfate and organic carbon reached 91.5% and 90.5% respectively.In the meantime,the generating rate of sulfide reached 47.8%.When the HRT was 7.7h, the removal rates of sulfate and organic carbon were 95.79% and 80%,and the generating rate of sulfide was 58.82%.The results showed that the conditions used in sulfate reduction meeting pretreatment of desulfurization-denitrification were HRT(7.710.2h) and pH(7.5-8).
