  • 摘要: 分别以含锰氧化物的陶粒和普通陶粒为填料,以O3体系和催化剂体系作为参照,研究臭氧在填料的异相催化条件下对苯甲酸的去除效果。结果表明:O3/催化剂体系具有更好的催化效果,同时O3/催化剂体系可有效改善废水的可生化性,并减少臭氧投加量和处理成本;初始pH为7~12时,废水的苯甲酸去除效果较好,且O3/催化剂体系的臭氧利用率比O3/普通陶粒体系、空柱的臭氧利用率更高,在初始pH为7时O3/催化剂体系的臭氧利用率提升效果最显著。
    Abstract: The removal rate of benzoic acid by ozone oxidation with heterogeneous catalysts comprising manganese oxide containing pottery grain was compared with that of common pottery grains,O3,and an O3/catalytic system.Results indicate an improved biodegradability and catalytic effect in O3/catalytic systems,which translate to a decrease in operation costs with ozone dosage.In addition,the removal rate of benzoic acid between pH 7 and 12 was enhanced and the ozone consumption rate in O3/catalysts was higher than that observed in O3 and O3/common pottery grain systems.A maximal improvement in the ozone consumption rate of O3/catalytic systems was observed at pH 7.
