摘　　要：进行了水力空化强化臭氧降解水中罗丹明的研究,考察得知罗丹明B溶液初始浓度、臭氧浓度、多孔板和入口压力等因素对水力空化强化臭氧降解罗丹明B影响显著,水力空化强化臭氧对罗丹明B的降解效果是单独使用臭氧的1.46倍,单独使用水力空化的14.5倍,因此水力空化联合臭氧降解罗丹明B有一定的研究价值。The degradation of Rhodamine B in water was systematically investigated with the O2 and hydrodynamic cavitation. The concentration of O3, geometrical parameters of multi-orifice plates, inlet pressure,and the initial concentration of Rhodamine B in the solution had great effect on the degradation rate.The efficiency of hydrodynamic cavitation with ozone on Rhodamine B degradation was 46 percent more than that of using ozone alone and 13.5 times more than that of individual used of hydrodynamic cavitation. Therefore it is worth to study hydrodynamic cavitation with ozone in degradation of Rhodamine B.
