0209343 Mathews The objective of the research is to investigate the feasibility of a novel concept in ozone generator design that should enhance mass transfer by in-situ ozone production using porous electrodes. In addition, enhanced reaction efficiencies will be achieved through the use of highly reactive ozone isotopomer species. Ozone is a powerful oxidant that is more potent than chlorine in the destruction of microbiological contaminants, and in the oxidation of recalcitrant organic compounds in wastewaters. Also, relative to chlorine, ozone is a benign oxidant since it does not generate a large number of toxic compounds as byproducts. However, ozone has not found widespread use due to its relatively high cost per unit volume of water treated, because of poor ozone mass transfer and reaction efficiencies. This exploratory research could help to improve the cost effectiveness of ozone treatment of wastewaters. ***

本研究的目的是探讨臭氧发生器设计中新概念的可行性，该概念应通过使用多孔电极原位臭氧生产来增强传质。此外，通过使用反应性很强的臭氧同位素体可以提高反应效率。臭氧是一种强大的氧化剂，在破坏微生物污染物和氧化废水中的难降解有机化合物方面比氯更有效。此外，相对于氯，臭氧是一种良性氧化剂，因为它不会产生大量的有毒化合物作为副产品。然而，由于臭氧传质和反应效率差，处理单位体积水的成本相对较高，因此臭氧尚未得到广泛使用。这项探索性研究有助于提高臭氧处理废水的成本效益。＊＊＊
