Abstract
본 발명은 지지체상의 값비싼 금속촉매의 재생공정과, 폐수를, 특히 할로겐 유기오염물을 함유하는 폐수를 촉매처리하는 공정에 관한 것이다. 촉매를 재생하는 공정은 전체공정 중의 한 부분이다.The present invention relates to a process for regenerating an expensive metal catalyst on a support and to catalyzing wastewater, in particular wastewater containing halogen organic contaminants. The process of regenerating the catalyst is part of the overall process.
