摘　　要：采用浸渍法对活性炭进行载铁改性,应用三维电化学技术处理氯霉素废水,考察电压大小、初始溶液p H、活性炭耐受性对去除率的影响。结果显示,体系的最佳实验条件为U=7 V,p H=3,去除率可以达到74. 17%。载铁活性炭经4次重复使用,去除率仅降低2. 66%,具有良好的耐受性。因此,基于载铁活性炭颗粒电极的三维电化学体系处理氯霉素废水是一种可行的方法。The activated carbon was modified with iron by impregnation method,and the chloramphenicol wastewater was treated by three-dimensional electrochemical technology.The effects of voltage,initial solution pH and activated carbon tolerance on the removal rate were investigated.The results showed that the optimum experimental conditions of the system were U=7 V,pH=3,and the removal rate could reach 74.17%.After four times of reuse,the removal rate of iron loaded activated carbon was only reduced by 2.66%,which had good tolerance.The three-dimensional electrochemical system based on iron loaded activated carbon particle electrode was a feasible method for the treatment of chloramphenicol wastewater.
