| 摘 要： | 糖蜜酒精废水是一种难降解的有机废水,主要成分为焦糖等色素类物质.利用沉淀法制备了PbwoJ光催化剂,将其应用于光催化降解糖蜜酒精废水降解反应中,考察了催化剂用量,空气流量,溶液pH值,助氧化剂及光照强度对糖蜜酒精废水脱色率的影响.研究表明,在紫外光辐照下,PbW04能有效地对糖蜜酒精废水进行光催化作用,过程为一级动力学反应.对于经30倍稀释的糖蜜酒精废水,添加4.0 g·L1的PbW04光催化剂,通入126 L.h1的空气,不改变废水的pH值及不添加助氧化剂H2O2的条件下,在300W高压汞灯照射下反应120 min,PbWO4光催化降解糖蜜酒精废水的脱色率为90.2%,COD去除率为78.6%,得到了较好的降解.
