摘要
水力空化技术是一种新的废水处理技术。为探讨操作条件和几何参数等因素对降解的影响,利用多洞孔板水力空化装置对含有若丹明B染色剂的模拟印染废水进行降解试验研究。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。
Hydrodynamic cavitation is a new technique in wastewater treatment.The degradation of rhodamine B has been studied on a hydrodynamic cavitation set-up using multiple hole orifice plates.The experimental results showed that rhodamine B is really decomposed by hydrodynamic cavitation.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.
