Young-shin Lee, Gimoon Sung* Dept. of Envronmental engineering Hanseo university, Seil engineering consultant Co. LTD* This study was performed to develop efficient way of treating livestock waste in Hong Sung County with Bacillus spp method. In this study, a pilot plant capable of treating 10 §©/day was installed without substantially remodeling the plant, and a mixture of Bacillus activated additives were revolved with precipitated wastes in a microbially reacting container. The reator was composed of three oxygen controlled tanks, and this method proved efficient way of reducing N and P simultaneously. The Bacillus colony was adsorbed to the reactor with KL-BC and exposed to bubbled air for 24 hours. Then 0.6 §© air/minute was supplied. As for sum up, the first oxygen controlled tank was kept DO 0.5 mg/l, the second one was kept DO 0.2-0.3mg/l, and the third was kept DO 0.1mg/l.
