  • 摘要: 为了提高工业聚集型村镇复合废水处理效率，对微波-均相Fenton技术进行了研究。基于Box-Behnken响应曲面法，重点考察了初始pH值、H2O2/Fe2+摩尔比、H2O2投加量、微波功率及微波辐射时间的单独及交互作用；建立以COD去除率为响应值的二次响应曲面模型并采用方差分析进行验证。结果表明，影响因子显著性排序为：初始pH值 > H2O2投加量 > 微波辐射功率 > H2O2/Fe2+摩尔比 > 微波辐射时间；其中初始pH和H2O2投加量之间交互作用显著；所建数学模型回归性较好，最优组合条件为：初始pH值3.43，H2O2投加量19.2 mmol·L-1，H2O2/Fe2+摩尔比39.42，微波辐射功率597.55 W，微波辐射时间5.12 min，该条件下COD实际去除率为95.3%，与模型预测结果相比偏差为4.7%。采用微波-均相Fenton法深度处理工业聚集型村镇复合废水，出水COD值完全满足《污水综合排放标准》（GB 8978-1996）一级排放标准COD≤100 mg·L-1。
    Abstract: In order to enhance the treatment efficiency of integrated wastewater, we evaluated the advanced treatment process by adopting the microwave (MW)-homogeneous Fenton method. Based on the Box-Behnken model, we adopted response surface methodology to evaluate the main influencing factors, including initial pH, the molar ratios of H2O2/Fe2+, the input amount of H2O2, MW power, and MW irradiation time, as well as the single-factor experiment and combined effects of MW. Moreover, a quadratic response surface model, adopting the response of COD removal efficiency, was also established and the model accuracy was confirmed with variance analysis. The results indicated that the influencing factors on COD removal efficiency ranked as follows: initial pH > H2O2 dosage > MW power > H2O2/Fe2+ molar ratio > MW irradiation time. Among these, the interaction between the initial pH and H2O2 input dosage was significant. In addition, the above response surface methodology showed a satisfactory mathematical regression model, with the optimized reaction conditions identified as initial pH of 3.43, H2O2 input dosage of 19.2 mmol·L-1, H2O2/Fe2+ molar ratio of 39.42, MW power of 597.55 W, and MW irradiation time of 5.12 min. The variance was about 4.7% compared with the predicted value. Accordingly, the effluent COD value for wastewater adopted with the MW-Fenton process was lower than 100 mg·L-1, which is in complete agreement with the demand of the Integrated Wastewater Discharge Standard (GB 8978-1996).
