摘　　要：EDTA清洗废液中COD和氨氮含量高,有机物降解难度大。文章阐述了通过高温蒸馏、低温结晶和催化氧化法处理EDTA清洗废液实现达标排放的工艺流程。EDTA清洗废液经处理后,检测COD和氨氮含量达到国家规定污水排放标准。The content of COD and ammonia nitrogen in EDTA cleaning wastewater is high, and the degradation of organic matter is difficult. This paper describes the process of EDTA cleaning wastewater treatment by high temperature distillation, low temperature crystallization and catalytic oxidation to achieve standard discharge. After treatment, the COD and ammonia nitrogen content of EDTA cleaning effluent reached the national sewage discharge standard.
