摘　　要：文章研究了特种光量子技术对水体中微量4-CP的降解情况,考察了溶液浓度、光解时间、溶液pH值以及加入氧化剂等对降解4-CP的影响,确定了适宜的反应条件,对光解产物进行了GC/MS分析及其降解机理探讨;研究结果表明,该种技术能有效降解微量4-CP,处理3 min时加入K2S2O8的4-CP溶液的CODCr去除率和脱氯率均达到100%。The degradation effect of low concentration of 4-chlorophenol in water was studied by using a special type of photon technique. The influence of concentration of 4-chlorophenol, the solution＇s p H value, the treating time, the oxidants and the appropriate technical parameter was preliminary discussed. The degradation products were analyzed by using the GC/MS method and the degradation mechanism was proposed. The results show that 4-chlorophenol was effectively degraded by the special photons technique. After treating for 3 min, the efficiency of dechlorination and removal efficiency of CODCr of 5 mg/L of aqueous 4-chlorophenol solution all reached 100% when K2S2O8 was added.
