Abstract
This paper describes the method of treating wheat straw pulp black liquor with microwave radiation. The granular activated carbon and CuO are used as a catalyst.Effects of effective factors such as the total amount, ratio, microwave power, time on treating process are studied. The reaction mechanism is also researched. The results indicate that the oxidative decomposition process of lignin or organic pollutants is combined action of activated carbon and CuO absorption-degradation with microwave induced oxidization. This approach is easy to operate, quickly to treat, completely to react and no new pollutants. So it is used to treat black liquor of containing organic pollutes which is hardly degraded.
