摘　　要：以传质理论和双层分阶段厌氧多生物相（TSMPA）理论为基础,设计了厌氧污泥-生物膜异波折板复合式反应器,进行为期12个月的生活污水处理中试研究.动态试验结果表明,在温度为25℃±2℃条件下,系统的最佳水力停留时间（HRT）为6 h.此时所对应的COD、TP、TN去除率分别为78.58%、35.15%、39.17%;最适厌氧污泥区百分比为45%-65%.HRT为6 h,温度降至7℃时所对应的COD、TP、TN去除率分别为64.37%、20.72%、23.65%;最大比甲烷产率为1.85 mL/（g.h）.结果表明,在北方地区低温条件下应用本技术处理低浓度生活污水可行.Based on the theories of mass-transfer and two-double integrated staged multi-phase anaerobe （TSMPA）, a pilot-scale opposite folded plate hybrid anaerobic reactor （OFPHAR） was designed to treat low concentration sewage. All the trial lasted 12 months and the results indicated that the optimal HRT was 6h. At this HRT, the COD, TP and TN removal rate were 78.58%, 35.15%, 39.17%, respectively, at 25℃ ＋ 2℃. The optimal rate of anaerobic section was 45 %-65 %. Controlled HRT = 6 h, the COD, TP and TN removal rate were 64.37 %, 20.72 % , 23.65 % , respectively, and the specific methane production capacity were 1.85 mL/（g· h） when the temperature decreased to 7 ℃ . The results of trial indicated that apply this OFPHAR to treat low concentration sewage at low temperature in north China is feasible.
