Zero-Liquid Discharge (ZLD) has received a lot of attention due to water scarcity and pollution. This article reviews the treatment of desulfurization wastewater in pretreatment, concentration and solidification with the trend of zero-liquid discharge in China. We summarize the advantages, disadvantages, performance, benefits and other characteristics of different ZLD technologies. Membrane-based technology is an effective means of recycling wastewater in ZLD systems. Therefore, we focus on the application of bipolar membrane electrodialysis (BMED) in desulfurization wastewater and high-salt wastewater treatment, discussing its limitations and solutions. In addition, several Chinese ZLD cases and economic analysis are introduced. It is believed that ZLD will become a new trend in desulfurization wastewater treatment in the future. Therefore, exploring new materials and technologies with low cost and high efficiency is the focus of future work.
零液体排放（ZLD）由于水资源短缺和污染问题受到了广泛关注。本文综述了中国零液体排放趋势下预处理、浓缩和固化脱硫废水的处理。我们总结了不同 ZLD 技术的优点、缺点、性能、效益等特点。膜基技术是 ZLD 系统中回收废水的有效手段。因此，我们专注于双极膜电渗析（BMED）在脱硫废水和高盐废水处理中的应用，讨论其局限性和解决方案。此外，还介绍了几个中国 ZLD 案例和经济分析。可以相信，ZLD 将成为未来脱硫废水处理的新趋势。因此，探索低成本、高效率的新材料和技术是未来工作的重点。
