Abstract

Abstract:

Response surface methodology(RSM) is used to design a process for the removal of bisphenol A by hydrodynamic cavitation with hydrogen peroxide(HC/H₂O₂), and the regression model of fitting quadratic polynomial is established. The results show the degree of influence of three factors on the removal effect of BPA:inlet pressure > hydrogen peroxide concentration > cavitation time. The optimized conditions for removing BPA by HC/H₂O₂ technology are:inlet pressure 0.31 MPa, hydrogen peroxide mass concentration 10.31 mg/L and cavitation time 138.81 min. Under this condition, the predicted value of BPA removal rate is 36.36%. According to the actual situation, the optimized parameters are only 0.12% different from the predicted values, which indicate that the regression equation has good fitting performance and the process parameters obtained by the model are reliable.

Key words: hydrodynamic cavitation, bisphenol A, response surface methodology, water treatment

摘要：

利用响应面法（RSM）对过氧化氢强化水力空化（HC/H₂O₂）去除双酚A（BPA）工艺进行设计，建立拟合二次多项式回归模型。结果表明，多项式模型的3个因素对BPA去除效果的影响顺序：入口压力>过氧化氢浓度>空化时间。HC/H₂O₂技术去除BPA的优化条件：入口压力为0.31 MPa，过氧化氢质量浓度为10.31 mg/L，空化时间为138.81 min。在此条件下BPA去除率的预测值为36.36%，根据实际情况修正优化参数与预测值仅相差0.12%，说明回归方程拟合性较好，模型得到的工艺参数可靠。
