【摘要】 采用循环式浆态光催化反应器对模拟废水(苯甲酰胺为模拟污染物)和生物制药废水(青霉素生产废水)光催化氧化特性进行了研究,系统地考察光催化剂的用量、污染物的初始浓度、反应时间、初始pH值等对光催化降解的影响。结果表明,此种光催化氧化技术去除有机污染物效果明显。采用采用悬环式浆态光催化反应器处理废水时,能够有效地提高光催化剂的利用率和催化效率。更多还原

【Abstract】 The technique of photocatalytic oxidation was employed in the treatment of the simulated wastewater with benzamide as a model pollutant, and the wastewater in biologic pharmacy of penicillin The effect of pretreatment of operation conditions such as dosage of photocatalyst, illumination time, initial content and pH value of the wastewater in a circulating slurry photocatalytic reactor was systematically discussed The results show that the application of photocatalytic oxidation technique in the treatment of wastewater in biologic pharmacy of penicillin is feasible and efficient, but it is affected by the operation conditions Compared with the stirred slurry reactor, the circulating slurry photocatalytic reactor exploited in our lab provides not only an excellent blend of catalysts and reactants, but also a high efficiency of UV light It can improve the output of treatment and reduce the dosage of catalyst更多还原
