Abstract

전기화학적 처리법에 의해 폐수내의 유기물과 질소의 처리에 대한 연구를 수행하였다. 이 방법을 이용하여 빠른 시간내에 유기물을 90%이상 제거가 가능하였다. 전류밀도가 증가할수록 반응속도 상수의 증가로 처리효율이 증가하였다. 본 실험을 통하여 DSA전극을 이용한 각종 산업현장의 폐수내에 유기화합물과 질소의 처리가 가능함을 확인하였다.

This research has been performed to study electrochemical treatment of organic compounds and nitrogen in wastewater. Organic compounds were removed through electrochemical treatment. The removal rate of organic compounds as increased with the increasing current density(A/cm(2)). Because reaction rate is increased. The results in this study suggested that DSA electrode was capable of removing organic compounds and nitrogen from industrial wastewater.
