As a new high-rate anaerobic reactor, technological features of ABSBR (Anaerobic Biofilm Sequencing Batch Reactor) and its preliminary study are introduced in this work. Two-phase ABSBR was used to treat wastewater under low concentration. The results showed that Two-phase ABSBR system can improve removal ratio of organism and suspend solid to 90% and 95% respectively with the hydraulic retention time (HRT) 6 hours. In addition, the system is more capable to resist impact on load and low temperature, which could improve the load capacity and discharged water quality of the reactor through the biofilm produced in the filler. The sequencing water level operation has solved ecological environment changes caused by the water level changes of ASBR.
