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.
盐水废水经常在各种工业领域中被发现，其中含有芳香族化合物。在将废水用于其他工艺步骤或排放到环境中之前，需要对这些化合物进行降解。已经有报道称嗜盐微生物可以有效地降解芳香族化合物，但它们在处理工业废水方面的应用却很少。用于工业废水处理的嗜盐过程需要满足一定的要求：连续的工艺模式、低运营成本、合适的反应器系统以及监测和控制策略。本综述的目的是提供对嗜盐微生物、芳香族生物降解原理以及含芳香族化合物和其他污染物的盐水废水来源的概述。最后，讨论了嗜盐废水处理的工艺实例和潜在的工艺监测策略。为了进一步说明嗜盐微生物在处理盐水废水方面的巨大潜力，并促进可实施工艺的开发，未来的研究应侧重于放大和创新的工艺监测和控制策略。
