试验结果表明：水力空化对若丹明B确实有降解作用，处理系统中存在最佳的孔板几何参数和操作运行条件，并且若丹明B的降解速率随修正空化数的减少而增大。

There are the optimal geometric parameters and operating conditions in the system and the degradation rate of rhodamine B increases with decreasing the value of the modified cavitation number.

通过调节通气提高空化初生的空化 数，工作时孔板旋转使堵塞物破碎和脱离。

Through the adjustment of ventilation, the nascent cavitation number of cavitation is improved and the pore plate can crush and separate clogs during operation.
