摘要
以制革的废革屑为载体,通过固载Fe(III),制备了一种新型UV-Fenton反应的非均相催化剂(Fe-CF),并研究其对造纸废水光解氧化的催化特性。研究发现,当Fe-CF用量为0.5g·L-1,H2O2用量17mg·L-1,在光照(254nm、10W)条件下,废水光解氧化110min后其总有机碳TOC去除率达50.3%。结果表明,Fe-CF能有效促进造纸废水中木素的光解氧化及矿化,降低污染负荷,并通过改变废水成分特性,改善其生化处理性。
A novel heterogeneous catalyst（Fe-CF）for Fenton reaction was prepared by immobilizing Fe （III） onto leather waste,and its catalytic activity for the UV-Fenton oxidation of wastewater from paper-making was investigated. The results indicated that the catalyst accelerated the decomposition and mineralization of lignin in the wastewater, and consequently improved the biodegradability of the wastewater. Catalyzed by Fe-CF（0.5g·L^-1）, TOC of wastewater was removed by 50.3% within 110 min under UV irradiation （254nm,10W） in the presence of H202 （17mg·L^-1）. Therefore, the use of Fe-CF in disposing wastewater discharged from paper-making may can be expected.
