空化效应在污水有机物降解中的应用

Application of cavitation for degradation of organic compound in wastewater

综述了空化效应产生的机理,分析超声降解水中有机污染物的机理、影响超声降解的因素,超声空化效应在实际工程应用中存在的效率低、能耗高。提出水力空化效应在有机物降解中的应用,利用水力空化效应降解有机物比超声降解的效率高、能耗低。

Mechanism of cavitation was introduced. Degradation mechanism of ultrasonic, the factors of influence were reviewed. Given the problems of this method in technical practice. The principle and the application of hydrodynamic cavitation in organic compound treatment were also introduced. Wastwater treatment with hydrodynamic cavitation is of higher efficiency and lower power cost.
