濾過法에 있어서 濾材(송이) 크기에 따른 褐藻類 抽出 廢水의 處理效果
姜永周,李民圭,吳泰文 제주대학교 1990 논문집 Vol.30 No.-
Efficient utilization of the scoria which are naturally abundant in parasitic volcano area of Cheju-do was tried to be linked with purification of the waste water contaminiating environment. A packed column for waste treatment was manufactured using scoria as medium, and the used waste water was the extract of a brown alga (Ecklonia cava) which is a raw material of sodium alginate. In this study the removal efficiency of suspended solid(SS), biological oxygen demand(BOD), and chemical oxygen demand(COD) was investigated under different conditions of medium size and operation time, The following results were obtained. 1. The smaller size of the medium gave the higher efficiency of water treatment. 2. The removal efficiency of SS was higher than that of BOD or COD at specific medium size. 3. The scoria was more effective on the removal of undissolved solid than dissolved one. 4. Filtration ability of the packed column was not decreased even after 5 day' continuous operation
