摘要
探讨了火电厂利用反渗透循环处理EDTA过洗水的系统。EDTA过洗水通过反渗透处理,淡水出口的水质指标达到废水排放标准,COD<130mg·L-1,EDTA浓度未检出,出口铁离子质量浓度为600mg·L-1。浓水出口废水用碱法回收EDTA,回收率约为80%。
EDTA wastewater in coal fired power plant was treated by reverse osmosis system to reuse. The effluent can reach standard of Wastewater emission. COD was less 130 mg·L^-1, EDTA was close to zero and concentration of iron was 600 mg·L^-1. The eighty percent EDTA in concentrated wastewater could be reclaimed with alkali method
