摘　　要：为了降低饮用水氯消毒过程中产生的消毒副产物(DBPs)2,6-二氯-1,4-苯醌(2,6-DCBQ)对人体带来的健康危害,以2,6-DCBQ为目标物,分析了在不同条件下高铁酸钾对2,6-DCBQ的降解效果和影响因素,探究了其降解机制和动力学规律.结果表明:随着高铁酸钾投加量的增加,2,6-DCBQ去除率明显提高;pH对2,6-DCBQ的降解效率影响较大,pH在4~6范围内,随着pH的升高,2,6-DCBQ降解效率有较为明显的提高;随着温度的升高,2,6-DCBQ的去除率逐渐增大.其降解过程属于一级反应动力学.In order to lighten the damage to human being of 2,6-dicholorbenzoquinone(2,6-DCBQ),which is a kind of disinfection by-products(DBPs)produced during chlorination process in drinking water.By taking 2,6-DCBQ as the research object,the removal efficiency of 2,6-DCBQ in different conditions and its influencing factors were investigated.The mechanism of degradation and kinetics were also explored.The results indicated that potassium ferrate had a greater degradation ability to 2,6-DCBQ,and the removal of 2,6-DCBQ increased obviously with the increase of potassium ferrate dosing quantity.The pH greatly influencedthe degradation of 2,6-DCBQ.When the pH ranged from 4 to 6,the removal of 2,6-DCBQ obviously increased with the increase of pH.The degradation efficiency of 2,6-DCBQ increased with increasing temperature,The rhythmical of 2,6-DCBQ degradation by potassium ferrate matched with the first-order kinetics model.
