摘要
研究了化工废水中有机污染物在颗粒活性炭(GAC)上的吸附行为,以及用微波辐照再生活性炭使污染物被诱导氧化的过程.结果表明,污染物在GAC上的吸附动力学为一级过程,修正后的Freundlich吸附等温线模型能更好地定量描述其吸附过程.再生后活性炭的碘值可以达到900mg·g-1左右,且能耗相对较低.
This paper describes an integrated granular activated carbon ( GAC ) adsorption-microwave (MW) induced oxidation process used for the treatment of high concentration organic wastewater. The research indicated that the adsorption accords with stair kinetic process and the modified Freundlich adsorption isotherm model can be properly used to formulate the adsorption behavior of phenol on GAC. Iodine number of the regenerating GAC reach over 900mg·g^-1, and the energy applied is lower in this treatment.
