摘要
采用 Ti OSO4 水解沉淀反应法 ,制备高活性 Ti O2 /累托石 .利用 SEM和 XPS等方法对其进行表征 .通过对造纸废水的光催化降解性能研究 ,确定了废水通过反应器的流量、废水 p H值和循环处理次数对光催化性能的影响 ;实验表明 :流量为 1 2 m L/min,p H=5 .0时 ,COD的去除率可达 88.76% .
A high active wastewater treatment materialTiO_2/rectorite powder is prepared by using TiOSO_4 hydrolysissediment reaction.Its characterization is showed by SEM and XPS.Studying on the photocatalytic degradation of paper industry wastewater,the influences of the rate of wastewater through the responser,the pH of wastewater and the frequency wastewater circulation are determined.The results show that when rate of flow is 12 mL/min,pH = 5.0,the removing rate of COD is up to 88.76%.
