Abstract
To better understand the promoting effect of the activation process, the performance of micro-bubbles for sodium persulfate activation was evaluated in this study. The degradation rate reached to 91.3% at 90th min in the micro-bubbles activated reactor (MAR), whereas reached to 85.7% at 250th min in the high temperature activated reactor (HTAR). Based on the fitted models, it can be indicated that the reaction rate constant was 2.45 times in the micro-bubbles activated reactor than that in the high temperature activated reactor. It can be concluded that micro-bubbles can effectively strengthen the activation process of sodium persulfate.
