摘　　要：以吡啶为模拟污染物,研究了铁碳微电解法降解含吡啶废水的影响因素。考察了铁碳投加量m(Fe/C)∶m(L)、pH值、曝气量以及反应时间4个因素对铁碳微电解法降解吡啶效果的影响,基于单因素实验结果,设计三水平四因素正交试验,确定最佳工艺参数。结果表明,各因素对含吡啶废水降解率的影响大小依次为:m(Fe/C)∶m(L)>反应时间>曝气量>pH值。最佳工艺参数为:m(Fe/C)∶m(L)为1∶1,反应时间为150 min,曝气量为1.2 L/min,p H值为4.0。在最佳工艺条件下,吡啶平均降解率为86.56%。To study the factors of degradation efficiency of pyridine wastewater by using iron-carbon micro-electrolysis process used pyridine as a model contaminant,the single factor of Fe/C dose(a mass ratio of m(Fe/C):m(L)),pH value,aeration rate and reaction time were discussed.Based on the results of the single factor test,the L9(3^4)orthogonal test was designed to determine the optimal parameters of this process.The results show that the influencing order of each factor follows:Fe/C dose(a mass ratio of m(Fe/C):m(L))>reaction time>aeration rate>pH value.The combination of optimum parameters was Fe/C dose(a mass ratio of m(Fe/C)∶m(L)=1∶1),reaction time of 150 min,the aeration rate of 1.2 L/min and the pH of 4.0.The average degradation efficiency of pyridine was 86.56%.
