다국어 초록 (Multilingual Abstract)

This paper was performed for characteristics of BOD removal, DO uptake and effluent water of SS by the BFB filled with activated carbon.
1) According to the experimental results, hydraulic retention time was 42 minutes, 3.42㎏-BOD/㎥·day of BOD volume loading rate, almost 85percent of organic removal characteristic, almost 40 percent upper of DO uptake rate, below 15㎎/ℓ of SS concentration rate of effluent water.
2) If media concentration was more than 257 ㎏/㎥, 30 percent of reactor, normal treatment rate was not anticipated.
3) As recirculation velocity was 0.57 ㎝/sec, the best optimum organic removal rate was 88.6 percent.
4) In the view of DO uptake, media concentration was 171㎏/㎥ and uptake rate was 56.4 percent in recirculation velocity 0.42 ㎝/sec.
5) The effluent SS concentration was below 15 ㎎/ℓ.
6) As characteristic of organic removal and DO uptake, the optimum treatment rates were recirculation velocity of 0.42 ∼ 0.66 ㎝/sec and media concentration of 222 ∼ 257 ㎏/㎥.
