Abstract
This study examined the influence of according as aeration/mixing time, fill time, aeration interval with Sequencing Batch Reactor(SBR) process of laboratory scale for removal of nitrogen and phosphorus in sewage of the cheju. The experiment according to aeration/mixing time controlled in 6 hr reaction time, each 90min/270min, 180min/180min, 270min/90min, 360min/0min. At this time, fill time controlled 6 hr same the reaction time. The experiment according to fill time controlled in 6 hr reaction time, each 2, 4 and 6 hr. At this time, aeration/mixjng time controlled 90min/270min from 1st experiment. The experiment according to aeration interval processes for compare with optimum condition from 2nd experiment and just changed aeration interval in reaction time. The result of experiment when aeration/mixing time controlled 90min/270min(1/3) and fill time controlled 6hr, also a repeated operation 6 times aeration/mixing in the reaction time, was showed the best removal efficiency of organics, nitrogen and phosphorus.
