采用化学预处理联合UV-Fenton光催化氧化法处理EDTA清洗废液,通过单因素实验和正交实验研究了各主要因素对EDTA回收效果及回收后废液COD去除效果的影响。结果表明,在最佳工艺条件下,EDTA的回收率在85%以上,COD去除率高达97.1%,处理后COD降至101.9 mg/L,达到排放标准。

The process,chemical pretreatment combined with UV-Fenton photocatalytic oxidation,has been used for treating EDTA cleaning wastewater. Based on single-factor and orthogonal experiments ,the effects of every main factor on EDTA recovery effectiveness and COD removing rate are investigated. The results show that under the opti-mal conditions,the EDTA recovery rate is over 85%,the COD removing rate is as high as 97.1%. After the treat-ment,the...
