摘　　要：针对废水低p H、高COD、可生化性差等特点,采用铁碳微电解工艺处理有机硅废水。基于BBD响应曲面法,考察铁碳填料投加量、pH和反应时间对COD去除率的单独及交互作用,并建立二阶数学模型。结果表明:各因素显著性由大到小顺序为:pH、反应时间、投加量,数学模型回归性较好。在p H=3.47、反应时间为2.74h,铁碳填料投加量为794.01g·L^(-1)的运行条件下,COD去除率的最大预测值为44.62%,与实际值的偏差仅为2.6%。The iron-carbon micro-electrolysis process was used to treat organic silicon wastewater with low pH,high COD,and poor biodegradability.Based on the BBD response surface method,the independent and interactive effects of iron-carbon filler dosage,pH and reaction time on COD removal rate were investigated,and a second-order mathematical model was established.The results showed that descending order of significance of every factors was as follows:pH,reaction time,dosing amount,and the regression of the mathematical model was good.The response surface method predicted that the maximum COD removal rate was 44.62%whose relative deviation from the actual value was only 2.6%,when the pH was 3.47,the reaction time was 2.74 h,and the dosage of iron-carbon filler was 794.01 g·L^(-1).
