摘　　要：三氧化钨是一种半导体光催化剂,可用于降解水中污染物。在用三氧化钨作为光催化剂处理亚甲基蓝模拟废水的反应中,通过单因素和正交实验,确定最佳处理条件为三氧化钨用量50mg、反应时间40min、H2O2用量4mL。并通过动力学研究,确定在不同三氧化钨光催化反应体系中的降解反应级数。Tungsten trioxide was a semiconductor photocatalyst which could be used for degradation of pollutants in water. In the treatment of methylene blue simulation wastewater, tungsten oxide was applied as a photocatalyst, and through the single factor and orthogonal experiments, the optimal processing conditions were obtained：tungsten trioxide content 50mg, reaction time 40min, the dosage of H2O2 4mL. By the kinetics study, the degradation reaction order was determined in different tungsten oxide photocatalysis reaction system.
