摘　　要：染料废水是工业废水的的主要来源之一,也是国内外公认的难处理的工业废水。本文探索了交联壳聚糖树脂负载的Fe2+催化剂的制备方法和条件,并以6-硝废水为研究对象,在非均相UV-Fenton体系下对其进行光催化降解。研究表明,在p H为3,催化剂用量0.6g,H2O2用量3.3m L,反应时间为80min,紫外功率为250W,降解率高达97.0%。Dye wastewater is one of the major sources of industrial wastewater, it is difficult to degradation. This paper explores the methods and conditions of preparation of Fe2＋catalyst supported crosslinked chitosan resin, degradated of 6- denitrification of wastewater. The results shows that pH 3, hydrogen peroxide 3.3ml, catalyst 0.6g, UV power 250w, the degradation rate of CODcr could reach to 97.0%.
