摘　　要：采用南京江心洲污水处理厂的厌氧消化污泥作为厌氧折流板反应器（ABR）的接种污泥,研究室温（25±5）℃条件下ABR对邻苯二甲酸二丁酯（DBP）降解的运行特性。结果表明,ABR在室温、容积负荷为0.9-1.8 kg/（m3·d）条件下启动运行30 d可以达到运行稳定,其COD去除率在90%左右。在负荷提高阶段,当水力停留时间（HRT）为12 h,容积负荷为2.0-6.8 kg/（m3·d）时,反应器对COD平均去除率大于85%;当HRT为12 h,容积负荷6.8 kg/（m3·d）时,COD去除率达90.7%,DBP降解率达87.3%。The start-up of an anaerobic baffled reactor（ABR） in treating Di-n-butyl phthalate（DBP） wastewater was studied when low influent load was used to culture the anaerobic digested sludge collected from Jiangxinzhou Sewage Treatment Plant in Nanjing.The operating characteristics of the ABR on DBP degradation were observed at ambient temperature（25 ± 5）℃.The result showed that the start-up operation was stable within 30 days when volumetric loading was 0.9 - 1.8 kg /（m3·d）,and the COD removal efficiency was about 90% at ambient temperature.In the load increased stage,when hydraulic retention time（HRT） was 12 h,volumetric loading was 2.0 - 6.8 kg /（m3·d）,the COD removal efficiency of the ABR reactor was higher than 85%.When HRT was 12 h,volumetric loading was 6.8 kg /（m3·d）,the COD removal efficiency was 90.7%,and DBP degradation rate was 87.3%.
