摘要:
针对超声空化处理量小、水力空化处理效果不够理想及臭氧虽然有较好的水处理效果，但臭氧容易从液体中冒出，造成臭氧的浪费的问题，探讨了增强水力空化的方法并采用水力空化与臭氧联合以提高臭氧利用率.首先研究不同通气量的臭氧单独作用时，对罗丹明B的降解率；其次研究臭氧与水力空化先后参与对罗丹明B降解时的降解率；最后将臭氧与水力空化进行联合，详细分析了1 mm孔径与2 mm孔径的两个穿孔板在固定条件下产生的水力空化与臭氧联合的降解效果，并改变孔径、孔数、进口压强等参数进行实验，研究不同条件下的降解效果.结果显示，臭氧对罗丹明B具有很强的降解作用，水力空化与臭氧先后降解对降解率提高不大，不同的穿孔板在不同的条件下产生的水力空化都可以大大提高臭氧的降解效果，水力空化使臭氧能够基本全部利用，避免了臭氧的浪费，同时臭氧分解成的微小气泡也增强了水力空化效应.
Abstract:
To solve the problems of insufficient effect of the hydrodynamic cavitation processing and the waste of ozone, the methods of enhancing hydrodynamic cavitation and improving the use of ozone by the combined use of the hydrodynamic cavitation and the ozone were discussed. First, the degeneration function of Rhodamine B by ozone was studied. Next, the degeneration rate of Rhodamine B by the ozone and the hydrodynamic cavitation successively was studied. At last, the degeneration effects produced by the combined use of the ozone and hydrodynamic cavitation under the fixed conditions by the two perforation plates of 1mm aperture and the 2 mm aperture were analyzed. The degeneration effects were studied under the dissimilar conditions of different parameters of diameter of aperture and the number of aperture and import intensity of pressure. The results show that the ozone has the very strong degeneration function to Rhodamine B, the degeneration rate cannot be raised greatly by the hydrodynamic cavitation and the ozone successively, the degeneration effects by ozone all may enhance greatly under the different conditions of the different perforation plate, the hydrodynamic cavitation enables the ozone to use completely and avoids the waste of ozone, simultaneously the small air bubble of ozone also strengthens the hydrodynamic cavitation effects.
