  • 摘要: 以模拟丙烯酸废水为研究对象,选择过氧化氢加入量、催化剂用量、反应时间、pH、温度为自变量,以丙烯酸废水TOC去除率为响应值,采用响应面分析法研究自变量及其交互作用对TOC去除率的影响,并通过回归方程求解和响应曲面分析,得到二次多项式回归方程的预测模型.结果表明,所选取的5个自变量与TOC去除率存在显著的相关性.确定Fenton氧化优化条件为:过氧化氢(30%)加入量15.4 mL·L-1,催化剂用量5.81 g·L-1,反应时间2 h,pH 3.0,温度25.0 ℃,优化条件下,丙烯酸废水TOC去除率可达99.0%.试验验证,实际值与模型预测值拟合性良好,偏差为3.23%.
    Abstract: In order to optimize the treatment of high-concentration acrylic acid wastewater by Fenton oxidation, response surface methodology was employed to investigate the effects of the independent variables and their interactions on the removal rate of TOC of acrylic acid wastewater. H2O2 dosage, catalyst dosage, reaction time, initial pH and reaction temperature were selected as independent variables, and the removal rate of total organic carbon (TOC) of acrylic acid wastewater as the response value. A predictive polynomial quadratic equation model was developed by solving the quadratic equation as well as analyzing the response surface plots and their corresponding contour plots. Response surface analysis results showed that the selected factors had significant correlation with the removal rate of TOC of acrylic acid wastewater. The optimum conditions of Fenton oxidation were determined to be 15.4 mL·L-1 H2O2(30%), 5.81 g·L-1 catalyst, 2.0 h reaction time, initial pH 3.0 and 25℃ reaction temperature. The removal rate of TOC of acrylic acid wastewater was up to 99.0% under the optimal conditions. The adequacy of the model equation for predicting the optimum response values was verified effectively by the experiment, and the experimental values agreed with the predicted values of the model equation with 3.23% deviation.
