초록

The recent rush to nationwide urban developments enlarges the ratio in areas with impermeable layers, thus making shorter the time to arrive to streams, and the quick water drainage system facilitated to effectively cope with flood has another problem to raise the flushing effect during storms due to more increased water flux speed within pipes. The present study in this regard satisfies treated water quality to the required level of effluent water by designing the system integrating rapid sedimentation filtration together with biofilm filtration capable of effectively soothing down the initial pollution caused by high velocity of rainfall runoff and flushing effect. In addition, the system designed eventually offers cutoff of construction and operation costs by settling down the difficulty in securing the plant lots and reduction of sludge generation. In other words, the methodological designed system bridging rapid sedimentation with biofilm-using filtration enables to overcome the problem of appropriate lots for plant in metropolitan cities and pave the way for reducing volume of sludges, accordingly leading to reduced maintenance costs. Thus, the study is focused on development of filtration system differentiated for abundant water flow during initial heavy rainfalls. As such, even in case of applying 100m/day as the highest biofilm filtration velocity, the findings addressed that the system fully met the requirement of effluent water by showing its averaged concentration values in terms of SS, CODMn, BOD, TN and TP were 9.1mg/L, 11.10mg/L, 9.6mg/L, 11.53mg/L and 0.23mg/L, respectively.
