Abstract
Recently the method using fixing biological contactor in treatment of sewage and wastewater has been propelling on the ground that it has advantages of reducing both motive and man power and applied treatment plants of this method are increasing gradually in Korea. After analysing the results from which real structure pilot plant had operated in the field with RBC sewage wastewater system-one of the fixing biological contact methods-for five months, this study was performed to investigate how to apply the standard of establishment that provided in article of sewage disposal facilities notified (act 8 of art 84) by the office of environment on May 16, 1984, to real treatment plant. The rotating velocity and the staying time of rotating disc have interrelation on removal efficiency of BOD. When circumferential velocity of rotating disc was ranged from 18 to 20 m per minute, economical price was the best. When the staying time was even about 120 minutes for that of home RBC facilities showed 90% or above of BOD removal efficiency of high concentration sewage also showed excellent efficiency ranged from about 85% to 90%.
