초록
합성 고분자 화합물의 생산과 ethanolamine(ETA, 원자력발전소에서 사용하는 pH 조절제)는 수질을 오염시키는 폐수를 발생한다. 본 연구는 유기물에 의해 유발된 COD를 감소시키기 위한 물리 화학적 처리법과 처리 약품을 개발하였다. $FeCl_2$와 $MgCl_2$를 1/1로 혼합하여 혼합응집제를 사용함이 COD 제거효율이 가장 좋은 결과를 얻었다. 유기물을 함유한 폐수처리에 복합응집제를 주입함으로써 COD제거율이 80%이상으로 나타났다.
The production of synthetic polymer compounds and ethanolamine (ETA, a pH control agent used in nuclear power plants) generates effluent that pollutes water. This study focused on the development of chemicals for the treatment of effluent and processes to reduce the COD level due to the presence of organic materials via physicochemical treatment. It was found that a mixed coagulant of $FeCl_2$ and $MgCl_2$ (1:1) was the most effective in treating effluent and reducing the COD level. When the mixed coagulant was injected into effluent including organic materials, the COD level was reduced by more than 80%.
