ABR反应器改进及常温启动的性能研究

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0．5-0．55kg／（m^3·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1．8kg／（m^3·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．

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

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/（m^3·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/（m^3·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.
