摘　　要：以某化工企业排放的高盐废水为目标,通过电渗析与反渗透耦合技术处理高盐废水,考察电渗析电压、补水流量及反渗透回收率对高盐废水处理结果的影响。结果表明,处理后的高盐废水可得到TDS为185.32 g/L的浓缩盐水和TDS为10 mg/L且不含TOC的淡水,分别回用于氯碱工业和中水系统。The high salinity wastewater discharged from a chemical enterprise was treated by electrodialysis and reverse osmosis coupling technology.The effects of electrodialysis voltage,makeup water flow and reverse osmosis recovery rate on the treatment results of high salt wastewater were investigated.The results showed that concentrated brine with TDS of 185.32 g/L and fresh water with TDS of 10 mg/L without TOC could be obtained from the treated high salinity wastewater,which could be reused in chlor alkali industry and reclaimed water system respectively.
