摘　　要：为了探讨废水中无机阴离子对电化学氧化降解对氯苯酚(4-CP)产生的影响。文章采用了自制圆形电化学反应器,通过改变模拟废水中电解质及其浓度来分析无机阴离子对4-CP去除率及矿化率的影响。试验研究表明,当废水中以OH-为主且浓度约为0.01 mol/L时,4-CP去除率可达81.99%,矿化率最高可达38.09%,而电化学能耗最低仅为35.57 kWh。P-Chlorphenol was selected as a model pollution substrate.The influences of inorganic anions on its degradation were investigated in the wastewater by changed the supporting electrolyses and its concentration at ambient temperature and pressure.Results showed that 4-CP could be removed efficiently by electrical chemistry oxidation with 81.99% removal rate when the concentration of OH-was about 0.01 mol/L in 2.5hours,the mineralization rate of 4-CP was up to 38.90%,and the electrochemical energy consumption was the lowest that was just only 35.57 kWh/（kg4-CP）.
