摘　　要：应用厌氧附着生长反应器,采用兼养同步脱硫反硝化工艺,以硝酸盐和亚硝酸盐作为电子受体,处理含有硫化物和有机物的模拟废水.结果表明,进水硫化物与有机物浓度分别为200,20mg/L时,其去除率分别可达99.9%和80.5%.同时,引入的电子受体硝酸盐和亚硝酸盐的去除率分别为83.0%和94.5%.利于兼养脱硫反硝化的葡萄糖负荷与醋酸钠负荷分别为50,25mg/(L?d),葡萄糖对兼养状态下自养脱硫反硝化的抑制作用小于醋酸钠.An anaerobic attached-growth reactor with mixotrophic desulfurization-denitrification technique, was applied to treat simulating wastewater containing sulfide and organic matter, using nitrate and nitrite as electron acceptors. When the concentrations of inflow sttlfide and organic carbon were 200mg/L and 20mg/L respectively, the removal efficiencies could reach 99.9% and 80.5% respectively. Meanwhile, the removal efficiencies of introduced nitrate and nitrite were 83.0% and 94.5% respectively. The loadings of glucose and acetate sodium, beneficial to mixotrophic desulfufizafiondenitrificafion, were 50mg/（L-d） and 25mg/（L.d） respectively. The inhibition action of glucose on autotrophic denitrificafion was smaller than that of acetate sodium on autotrophic denitrification under mixotrophic state.
