摘　　要：采用微电解/曝气生物流化床(ABFT)组合工艺处理高盐化工废水,考察高盐条件下ABFT系统内污泥浓度和生物群落的变化以及对COD和NH4^+-N的去除效果。试验结果表明,高盐(盐度为2%)化工废水经预处理后,40d可完成ABFT系统的生物驯化培养,污泥中耐盐生物菌群数量增多,出水COD和NH4^+-N分别稳定在300和15mg/L以下,对COD和NH4^+-N的去除率分别为81.5%和92%。High salt chemical wastewater was treated by combined process of micro-electrolysis and aerobic biological fluidized tank ( ABFT), and sludge concentration changes and biological community of ABFT system and the removal effects of COD and NH4^+- N under high salinity conditions were investigated. The results showed that the domestication of the ABFT system could be completed within 40 days after pretreatment of the chemical wastewater with high salinity ( salinity of 2%), where the number of halotolerant bacteria in the sludge increased. Effluent COD and NH4^+- N were always less than 300 mg/L and 15 mg/L, and the removal rates of COD and NH4^+- N were 81.5% and 92%, respectively.
