▎ 摘　　要

NOVELTY - Composite catalyst comprises carrier and modified metal supported on carrier. The modified metal is nickel, cobalt, copper and manganese. USE - The composite catalyst is used for degrading high molecular organic compound for treating wastewater and solid waste containing polymer compound (claimed). ADVANTAGE - The catalyst has good degradation effect for high concentration organic compounds, difficult to degrade and long-chain polymer organic compounds, low cost and fast and high efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for degrading high molecular organic compound comprising degrading macromolecular organic compounds by electron beam irradiation in the presence of composite catalyst.
