基于Matlab拟合的生态混凝土对总氮去除效果研究

Based on Matlab Simulation of Ecological Concrete Research on Total Nitrogen Removal Efficiency

为了深入研究生态混凝土对总氮的去除效果,采用物理模型构建不同配合比的生态混凝土试块,利用Matlab拟合四个试验点总氮随时间的变化规律。结果表明,生态混凝土对总氮有很好的去除作用,各试验点总氮随时间变化规律符合4次多项式。四个试验点对总氮去除率分别为31.9%、42.2%、48.4%、45.1%,可见生态混凝土试块对总氮去除率与孔隙率大小相关,孔隙率越大去除效果越明显。

In order to further study of the ecological concrete removal efficiency of total nitrogen, the physical model was used to construct the different proportions of ecological concrete block, using Matlab simulation of four sites over time and the change law of total nitrogen. The results showed that the ecological concrete has good removal effect to total nitrogen, the test of total nitrogen variation law with time in line with the four polynomial. Four sites for total nitrogen removal rate were 31.9%, 42.2%, 48.4%, 42.2%, visible ecological concrete block related to the total nitrogen removal rate and porosity size, the greater the porosity, the more obvious the removal effect.
