Establishing and application for mathematical model of high performance organic adsorption film

采用自行合成的有机吸附膜富集净化水中微量有机污染物,依据有机吸附膜对水中有机污染物物理吸附的过程,在大量测试数据基础上建立高效有机吸附膜吸附饮用水中氯仿的数学模型,并用统计方法求取了模型中的参数.应用此模型研究了萃取时间、水样中氯仿的本底质量浓度和高效有机吸附膜厚度等对萃取效率的影响.通过有机吸附膜对模拟饮用水中氯仿的吸附实验,证明该模型能较准确地模拟高效有机吸附膜吸附氯仿的过程,模型计算数据与实验数据吻合较好.

The organic adsorption film synthesized by investigator were used to purify the trace organic pollutant in water. According to the physical adsorption process of organic adsorption film adsorbing trace organic pollutant in water, the mathematical model for high performance organic adsorption film was established based on great number of test data, and the parameters of this model was calculated. By this model, the effects of adsorption time, concentration of chloroform in drinking water anti film thickness on the adsorption efficiency were discussed. The model application test of organic adsorption film adsorbing trace organic pollutant in water proved that it can accurately simulate the process of high performance organic adsorption film adsorbing chloroform in drinking water, and the model data accorded with the experimental data.
