摘　　要：利用钛酸丁酯和陶瓷鲍尔环为原料,采用溶胶-凝胶法制备了复合TiO2-陶瓷鲍尔环光催化剂。利用该复合光催化剂对某厂的中药废水进行了光催化无害化处理,通过分析处理后COD降解率表明,对100mL中药废水进行光降解,当H2O2添加量为1.5mL,复合光催化剂用量为20粒,催化环境pH为9时,光催化降解效果最好,3hCOD降解率可达91.85%。Abstract:In this paper, the composite TiO2-ceramic Bauer ring photocatalyst was prepared by sol-gel method using butyl-titanate and ceramic Bauer ring as raw materials. The photocatalytic degradation rate of 100 mL Chinese medicine wastewater was analyzed. The results showed that the photocatalytic COD degradation rate of 100 mL Chinese medicine wastewater was 91.85% in 3 hours when the dosage of hydrogen peroxide was 1.5 mL, the dosage of 20 composite photocatalysts and the pH of catalytic environment was 9.
