中文摘要: 基于反渗透(Reverse Osmosis, RO)技术处理钢铁企业高氯循环水实际工艺参数,研究了响应曲面法设计下温度、压力、pH各因素不同水平对RO膜通量和截留率的影响程度,建立数学模型并进行三因素的优化设计分析。研究表明:各因素对膜通量的影响程度为:压力(B)>温度(A)>pH(C);对截留率的影响程度为压力(B)>pH(C)>温度(A);各因素之间交互作用对膜通量和截留率的影响均为:温度与pH交互项(AC)>压力与pH交互项(BC)>温度与压力交互项(AB)。当温度为26℃,压力为0.7MPa,pH为8时,可得到理论最优的RO分离效果:膜通量为21.716 L/(m2?h)、截留率为96.226%。经实验验证,预测值实际误差较小,表明该模型能较好对实际情况进行预测。对使用后的RO采用 SEM-EDS手段检测发现,膜面产生无机污染,其中大部分为钙盐。
Abstract:Based on the actual process parameters of methamphetamine (RO) technology to technical processing of steel companies, the impact of different levels of the temperature, pressure, and pH of various factors under the design of the surface of the surface of the surface of the surface of the surface of the curved surface is studied. The model and three factors are optimized design analysis. Studies have shown that the impact of various factors on the amount of membrane flux is: pressure > temperature> pH; the degree of impact on the cutting rate is pressure (B) > pH (C) > temperature (A) ;Temperature and pH interaction term (AC) >Pressure and pH interaction term (BC) >Temperature and pressure interaction term (AB) . When the temperature is 26 ℃, the pressure is 0.7 MPa, and the pH is 8, the theoretical optimal RO separation effect can be obtained: the membrane flux is 21.716 L/(m2.h), and the intercept rate is 96.226%. After experimental verification, the actual error of the prediction value is small, indicating that the model can better predict the actual situation. The use of ROs using SEM-EDS is detected and found that the membrane surface produces inorganic pollution, most of which are calcium salts.
