摘　　要：采用Fe/C微电解法对化工废水进行处理,得到单因素条件下的最佳实验条件,并利用Box-Behnken响应面法对实验条件进行了优化和验证,考察各因素的交互作用。结果表明:各因素对COD去除率的影响依次为:Fe/C投加量>初始pH值>微电解时间,对B/C比的影响依次是微电解时间>初始pH值>Fe/C投加量;优化后最佳反应条件是pH为4.13,Fe/C投加量为351.9 g/L,微电解时间为118.5 min,COD的去除率达23.74%,B/C比为0.402,与模型预测值相差0.99%(<2%)和1.08%(<2%)。因此,采用响应面法对Fe/C微电解处理化工废水工艺预测具有良好的有效性和可靠性。The optimum experimental conditions for the treatment of chemical wastewater by Fe/C microelectrolysis under single factor conditions are obtained,and the experimental conditions are optimized and verified by response surface method.The results show that:the influence scale of each factor on COD removal rate is Fe/C dosage>initial p H value>micro-electrolysis time.The influence scale on the B/C ratio is micro-electrolysis time T>initial p H value>Fe/C dosage.The optimized optimal reaction conditions are p H 4.13,Fe/C dosage 351.9 g/L,micro-electrolysis time 118.5 min,the COD removal rate 23.74%and the B/C ratio 0.402,which differ from the actual average value by 0.99%(<2%)and 1.08%(<2%).Therefore,it can be concluded that the response surface method is effective and reliable in predicting the process of Fe/C microelectrolysis treatment of chemical wastewater.
