In this study, Anaerobic beads with 0.85~1.45 ㎜ diameters were produced by direct injection and mixing(100 rpm for 3 minutes) of anaerobic sludge 200 ㎖(average MLSS concentration 38,000 ㎎/L) and 1.5% sodium alginate solution. The paper wastewater treatment of the sequencing batch reactor with anaerobic biobeads could achieve about 85% COD removal after 6 days. With this remarkable results of this study, it can apply to the way of the removal efficiency stabilization and starting up of the UASB reactor because it didn’t happen the sludge rising and washing out although the maximum upflow velocity increased to 0.26 m/hr.
