摘要
在国家已将污水纳入水资源管理体系的背景下,节水减排已成为企业生产优化的重要方向。炼化废水由于其产生量大、水质成分复杂等特点,是炼化行业实现节水减排的难点。因此,从炼化废水中回收可利用水资源的零排放技术得到了广泛关注。目前已开发出以反渗透膜(RO)、电渗析(ED)、膜蒸馏(MD)等方法为核心的零排放技术(ZD)。文章分析了炼化废水的处理现状和实施零排放所面临的诸多问题,综述了针对废水零排放的处理技术,对零排放技术在炼化企业中的应用进行了展望。
With wastewater incorporated into the national water resource management system,water conservation and emission reduction have become key directions for production optimization in enterprises.Refining and petrochemical wastewater,due to its large volume and complex composition,represents a major challenge for achieving water conservation and emission reduction in the industry.Zero discharge(ZD)technologies aimed at recovering reusable water resources from refining wastewater have gained wide attention.Current ZD technologies are primarily based on reverse osmosis(RO),electrodialysis(ED),and membrane distillation(MD).This paper analyzes the current status of wastewater treatment and the challenges of achieving zero discharge,reviews related treatment technologies,and provides prospects for the application of ZD technologies in refining and petrochemical enterprises.
