Sequencing batch reactor(SBR) process changed spatial concept for temporal concept of established wastewater treatment system. It is possible to apply a wastewater process structure without a considerable change. In addition, if it is operated with mixed processes such as anaerobic, aerobic and anoxic, it can remove organic matters, nitrogen and phosphorus. B3(Bio-Best-Bacillus system) is applied to accomplish a removal of nitrogen and phosphorus. When high-concentrated Bacillus sp. intakes nitrogen and phosphorus, it is composed to cells and then, denitrification is occurred and phosphorus is removed. Therefore, if SBR and B3 processes were applied at the same time to wastewater system in the Korea, the removal efficiency of nitrogen and phosphorus will be more efficient than before. The experiment was conducted with lab-scale reactor and the operating condition for reaction time is separated to high-aeration, low-aeration and anoxic. The results showed that more than 90% of COD, nitrogen and phosphorus overall removal efficiencies were indicated in the early of reaction time and the COD concentration of effluent in HRT 6 hours and 8 hours were 16 and 12 mg/L respectively. The nitrogen concentration of effluent were 20.6 and 17.1 mg/L respectively, and each of removal efficiency were 52% and 60%. The phosphorus concentration were checked to 1.45 and 1.33 mg/L in effluent respectively, and the removal efficiency were 73.5% and 75.4%. In the batch experiment with ammoniacal nitrogen and nitrate nitrogen, most of nitrate nitrogen remained in the reactor, so it was supposed that denitrification was not proceeded practically in a regular DO concentration, and ammoniacal nitrogen was removed regularly regardless of nitrate nitrogen.
