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被芳香族化合物污染的盐水中的潜在应用。

在各个工业部门中经常可以发现被芳香族化合物污染的盐水。这些化合物需要先降解，然后再用于其他工艺步骤中或再排放到环境中。据报道，嗜盐菌能有效降解芳香族化合物，但很少用于处理工业废水。用于工业废水处理的嗜盐工艺需要满足某些要求：连续的工艺模式，较低的运行费用，合适的反应器系统以及监测和控制策略。这篇综述的目的是概述嗜盐微生物，芳香族生物降解的原理以及含芳香族化合物和其他污染物的盐水废水的来源。最后，讨论了用于咸水废水处理的过程示例以及潜在的过程监控策略。为了进一步说明嗜盐菌在盐业废水处理中的巨大潜力并促进现成工艺的发展，未来的研究应集中于扩大规模和创新的工艺监测与控制策略。
