二氧化钛光催化技术处理制药废水的实验研究

通过改变二氧化钛浓度、调节pH值、添加H2 O2及铁离子浓度等实验方法，验证了二氧化钛光催化反应处理制药废水的效果。根据测定制药废水中氨氮、COD浓度，计算氨氮、COD的去除率，得出二氧化钛光催化反应的最佳反应条件，为实际应用提供依据。

Research of Pharmaceutical Wastewater Treatment by Technique of TiO2 Photocatalysis

The study focus on using some methods such as changing the concentration of titanium dioxide , adjusting the pH , adding H2 O2 and iron ion concentration to verify the treatment efficiency of using the titanium dioxide photocatalysis to deal with pharmaceutical wastewater .According to the determination of ammonia nitrogen and COD concentration in the pharmaceu -tical wastewater , we calculate the removal rate of ammonia nitrogen and COD .The optimum reaction conditions for titanium dioxide photocatalysis reaction are proposed which provide a basis for practical application .
