[目的]为提高电镀园区废水回用率，实现水资源高效循环利用，满足电镀生产线对回用水质的要求。[方法]采用“物化+离子交换+生化+双膜法+阴阳床纳米树脂”多级耦合工艺，分别去除电镀园区废水中的重金属、降解有机物、脱氮除磷及深度脱盐。[结果]经本套工艺处理后，出水镍浓度小于0.1 mg/L,COD(化学需氧量)去除率达80%，电导率小于10μS/cm，整体回用率达60%以上。[结论]该工艺满足复杂成分电镀废水处理的需求，可将产水回用到电镀生产线上。
Abstract：[Objective] This study aimed to enhance the wastewater reuse rate in electroplating parks, achieve efficient water resource recycling, and meet the water quality requirements for reuse in electroplating production lines. [Method] A multi-stage integrated process combining physicochemical treatment, ion exchange, biochemical treatment, dual-membrane technology(ultrafiltration + reverse osmosis), and mixed-bed nano-resin was employed to remove heavy metals, degrade organic matter, eliminate nitrogen and phosphorus, and deeply desalinate electroplating wastewater. [Result] The treatment process achieved effluent with nickel concentration below 0.1 mg/L, COD(chemical oxygen demand) removal efficiency exceeding 80%, conductivity under 10 μS/cm, and total reuse rate of over 60%. [Conclusion] The proposed process meets the needs of electroplating wastewater treatment with complex components and enables the reuse of effluent in electroplating production lines.
