为了提高臭氧电解过程的臭氧消耗效率（OCE），本研究介绍了一种由臭氧接触器（间接臭氧注入系统）独立的电解池和三维电极组成的臭氧电解系统。与之前的反应器相比，该反应器成功地提高了OCE和1,4-二氧六环降解率与臭氧注入率（RDO）的比值。由于降低了阴极上的电流密度，三维电极也有助于改善OCE和RDO。臭氧间接注入系统为反应器设计提供了较高的自由度，有利于臭氧电解技术在实际水处理中的应用。
For improving the ozone consumption efficiency (OCE) of the ozone-electrolysis process, an ozone-electrolysis system with an independent electrolytic cell from an ozone contactor (indirect ozone injection system) and a three-dimensional electrode were introduced in this study. The reactor successfully enhanced the OCE and the ratio of 1,4-dioxane degradation rate to ozone injection rate (RDO) in comparison with the previous reactor. The three-dimensional electrode also contributed the improvement of the OCE and the RDO due to lowering the current density on the cathode. As the indirect ozone injection system allows higher degree of freedom for the reactor design, it is useful for application of ozone-electrolysis to practical water treatments.
