BAP/O3复合氧化体系对SMP的降解性能
Degradation of SMP by BAP/O3 composite oxidation system
摘要
Abstract
In this study,the degradation efficacies of sodium bicarbonate-activated hydrogen peroxide(BAP),Fenton advanced oxidation(Fenton),ozone oxidation(O3),and their composite processes on sulfonated phenol-formaldehyde resins(SMP),which are the main components of trisulfuric drilling fluids,were compared.The BAP/O3 composite system was selected as the best process for degrading sulfonated phenolic resins,and the composite oxidation interaction mechanism was also investigated.The results showed that the order of the composite formulations for SMP removal was(BAP/O3)＞(BAP/Fenton/O3)＞(BAP/Fenton)＞(Fenton/O3).Except for the segmental composites of BAP and Fenton with a better performance,other three composite formulations adding at the same time also achieved better degradation effects.BAP/O3 composite achieved the optimal degradation and mineralization of SMP with the maximum removal rate of 95.92％.The quenching experiments showed that the main active oxidants in the BAP/O3 composite oxidation system were carbonate radicals(·CO3-),superoxide radicals(O2-·)and hydroxyl radicals(OH),of which ·CO3- and its induced secondary reaction played key roles.关键词
