摘　　要：通过正交实验,量化了反渗透膜元件产水量标准化模型的偏差,明确了给水盐浓度是影响模型计算结果准确性的最显著因素.通过引入修正系数α,对模型中的给水盐浓度校正系数进行了修正.结果表明,修正后的模型显著提高了计算结果的准确性.Through orthogonal experiments,this paper quantifies the deviations produced by the normalization model of RO membrane elements’ permeate flow,and shows that the most significant factor affecting the accuracy result of the model is feed concentration.The correction factor of feed concentration is further amended by introducing a cor-rection coefficient α.The results indicate that the accuracy of the optimized model is improved significantly.
