This work investigates the feasibility of ozonation for destroying phenol and removing organic matter in saline media. The reaction lumped kinetics was followed using the GLKM (General Lumped Kinetic Model). The main intermediate compounds were: catechol, hydroquinone, 4,4'-dihydroxybiphenyl, and 4-bromophenol. It could be noted no significant differences in phenol degradation, mineralization rates, and toxicity removal up to 2 g L(-1) of salt. So, ozonation appears to be a technology that can be used in low salinity media, which is characteristic of waters destined to reuse and recycling programs inside industries.
本研究探讨了臭氧化法在含盐介质中破坏苯酚及去除有机物的可行性。采用通用集总动力学模型（GLKM）跟踪反应集总动力学。主要中间化合物为：邻苯二酚、对苯二酚、4,4'-二羟基联苯和4-溴苯酚。值得注意的是，在盐浓度高达2 g L(-1)时，苯酚降解、矿化率和毒性去除方面没有显著差异。因此，臭氧化似乎是一种可用于低盐度介质的技术，这是工业内部水再利用和循环利用计划所涉及水体的特征。
