몇 가지 여재를 이용한 부영양수 내의 조류 및 인 제거효과 = The Removal of Algae and Phosphorus in Eutrophic Waters Using Various Filter Media

다국어 초록 (Multilingual Abstract)

In this study, the four different filter media (sponge, volcanic stone, activated carbon and magnesium hydroxide) were tested for the removal of algae and phosphorus in the two eutrophic water samples (natural water and artificial algal culture with BG- 11 medium). These filter media were used in the column device as single or combined applications. The effect of the Mg(OH)2 on phosphorus removal was examined using different particle sizes (/2 mm and ¤2 mm) and concentrations (0, 10, 50 and 100 g L-1) of magnesium hydroxide. The removal efficiency of phosphate by magnesium hydroxide was increased with longer experimental time and higher concentration. However, there was no significant difference in the degree of phosphorus removal between any two particle sizes (1 mg P L-1: F=0.109, P=0.685; 10 mg P L-1: F=1.542, P=0.355). Among the four media, activated carbon showed the most potent effect on the removal of both algae and phosphorus. The highest removal efficiency of algae and phosphorus was obtained by combining four columns of each filter medium. Interestingly, integration of four filter columns showed higher removal efficiency than activated carbon alone. The highest removal efficiency by integrated filter columns seemed to be caused by a synergistic effect of combined activated carbon and magnesium hydroxide.
