Saline wastewater contaminated with aromatic compounds can be frequently found in various industrial sectors. Those compounds need to be degraded before reuse of wastewater in other process steps or release to the environment. Halophiles have been reported to efficiently degrade aromatics, but their application to treat industrial wastewater is rare. Halophilic processes for industrial wastewater treatment need to satisfy certain requirements: a continuous process mode, low operational expenditures, suitable reactor systems and a monitoring and control strategy. The aim of this review is to provide an overview of halophilic microorganisms, principles of aromatic biodegradation, and sources of saline wastewater containing aromatics and other contaminants. Finally, process examples for halophilic wastewater treatment and potential process monitoring strategies are discussed. To further illustrate the significant potential of halophiles for saline wastewater treatment and to facilitate development of ready-to-implement processes, future research should focus on scale-up and innovative process monitoring and control strategies.

嗜盐微生物在生物处理受芳烃污染的工业过程盐水中的潜在应用

被芳香族化合物污染的含盐废水经常出现在各个工业部门。这些化合物需要先降解，然后再将废水重新用于其他工艺步骤或释放到环境中。据报道，嗜盐菌可以有效降解芳烃，但它们在处理工业废水中的应用很少。工业废水处理的嗜盐工艺需要满足一定的要求：连续工艺模式、低运营支出、合适的反应器系统以及监测和控制策略。本综述的目的是概述嗜盐微生物、芳香族生物降解原理以及含有芳香族化合物和其他污染物的含盐废水的来源。最后，讨论了嗜盐废水处理的工艺示例和潜在的工艺监控策略。为了进一步说明嗜盐微生物在含盐废水处理方面的巨大潜力并促进可立即实施的工艺的开发，未来的研究应侧重于扩大规模和创新的工艺监测和控制策略。
