ABR反应器改进及常温启动的性能研究

Research on the improvement and start-up of anaerobic baffled reactor at normal temperatures

摘要: 为了加强处理系统的效果及稳定性，试验通过加大第1和第4隔室长度的方式，对传统ABR反应器做出了改进.在常温(18~32 ℃)下采用HRT逐步减小而有机负荷逐步提高的方式启动ABR系统，结果表明，启动第一阶段有机负荷保持在0.5~0.55 kg/(m³·d)，第二、三阶段负荷逐步增加，系统COD去除率高，当容积负荷为1.8 kg/(m³·d)时，COD去除率高达85.2 %以上，改进后的反应器表现出了良好的抗冲击能力，说明常温下采用低负荷方式启动ABR是可行的.

Abstract: To improve the disposal effect and stability of traditional anaerobic baffled reactor, the first and fourth compartments were increased.Started ABR by decreasing HRT and increasing organic load at normal temperature (18~32 ℃), it turned out that load was maintained at 0.5~0.55 kg/(m³·d) in the first stage of start-up period, then it was increased gradually in the second and third stages, when it reached 1.8 kg/(m³·d), the removal rate of COD was above 85.2 %.Advanced reactor showed a good surge withstand capability, this meant that starting ABR with loworganic loading at normal temperature is feasible.
