초록

국내 석탄 화력발전소에서 폐기되는 석탄회를 이용하여 제올라이트를 합성하였으며, 이를 이용하여 폐수 중 암모니아성 질소 제거용 흡착제로서의 활용가능성을 조사하였다. 실험결과 산에 의한 전처리 과정이 중요하고, 4M-NaOH, 반응시간 4 h, pH 7 ~ 9.5에서 합성한 제올라이트가 가장 우수한 흡착성능을 보였으며, 이는 상업용 5A형 제올라이트와 비슷한 80%의 흡착성능을 보였다.

Synthetic zeolite was prepared from coal fly ash which and been abandoned from a domestic power plant as wastes, and was investigated as an absorbent for removal of ammonia from the waste water. The results suggest that pH control step in the synthesis process was an important factor for the removal capacity due to the presence of alkaline materials such as CaO and MgO in fly ash. Accordingly the zeolite synthesized at 4 M-NaOH and 4 hrs under controlling the pH 7 ~ 9.5 showed the removal efficiency of 80% as much as the commertial one at its highest rate.

Keywords:coal fly ash;waste water treatment;zeolite;absorption;ammonia removal
