摘　　要：对K_(2)FeO_(4)氧化页岩气压裂返排液降解有机物动力学、机理及特征污染物邻苯二甲酸二丁酯(DBP)降解机理进行实验分析。通过单因素实验探究确定动力学,采用GC-MS分析有机物变化及降解机理。实验结果表明:K_(2)FeO_(4)氧化页岩气压裂返排液有机物降解符合两阶段反应动力学,最佳反应条件为K_(2)FeO_(4)浓度1500 mg/L,初始pH=9.0,温度为25℃。通过GC-MS分析K_(2)FeO_(4)氧化DBP降解过程中间产物,并提出了降解DBP的可能途径。The kinetics and mechanism of organic matter degradation in K_(2)FeO_(4) oxidized shale gas flowback water,as well as the degradation process of the pollutant dibutyl phthalate(DBP),were experimentally analyzed.The kinetics were determined by single factor experiment,and the change and degradation mechanism of organic matter were analyzed by GC-MS.The results showed that the degradation of organic matter in K_(2)FeO_(4) oxidized shale gas flowback water could be described by two-stage reaction kinetics.The optimal reaction conditions were K_(2)FeO_(4) concentration of 1500 mg/L,initial pH=9.0,and temperature of 25℃.The intermediates of DBP degradation by K_(2)FeO_(4) oxidation were analyzed by GC-MS,and possible ways of DBP degradation were proposed.
