光催化协同臭氧深度处理高浓度制药废水

摘要

The process of photocatalysis combined with ozone was established for treatment of pharmaceutical wastewater.The results showed that a synergistic effect was observed between photocatalysis and ozone.The COD removal increased with the increasing catalyst amount and ozone flow rate.The effect of initial pH value on COD removal was relatively small.%采用光催化协同臭氧技术处理高浓度制药废水,研究了光催化/臭氧法处理的主要影响参数。结果表明光催化法和臭氧法之间存在明显的协同作用。随着催化剂添加量的提高,废水COD的去除率逐渐提高,增加臭氧的流量有利于提高COD去除率;溶液初始pH值则对降解的影响较小。
