摘　　要：在中低温厌氧条件下,采用IC厌氧反应器降解BDE-209废水。结果表明:在温度为18～30℃,反应器运行62 d,第14天反应器出现颗粒污泥,随着运行时间和容积负荷的增加,颗粒污泥的粒径不断增大。当进水ρ(COD)为11 000 mg/L,控制HRT为24 h,COD容积负荷为11.7 kg/(m3.d)时,COD去除率稳定在70%以上,BDE-209降解效率达26.8%。The effluent containing decabromodiphenyl ether（BDE-209） was treated by internal circulation（IC） anaerobic reactor under anaerobic conditions at low temperature.The results indicated that at 18 ℃ to 30 ℃,the reactor operated for 62 d,and granular sludge occurred in the reactor on the 14th day.The size of granular sludge continuously increased with the running time and loaded volume.When the COD of the influent was about 11000 mg/L,the hydraulic retention time（HRT） was kept in 24 h and the loaded volume of COD was 11.7 kg/（m3·d）,the removed rate of COD was over 70%,the degradation efficiency of BDE-209 was 26.8%.
