摘要: 在实验室条件下模拟了人工土层快滤系统,运用均匀设计原理来寻求最佳COD去除率的主要设计参数的方法,即人工土组成(石英砂/土)、运行周期(淹水时间、湿干比)等。用倒数方程法来求得系统的COD稳定去除率,利用逐步回归法,建立了人工快速渗滤系统的主要设计参数与COD去除率之间的多元线性回归模型。研究结果得到的主要参数优化方案是石英砂/土=1.073,淹水时间=4h,湿干比=1/8,理论最大COD去除率为84.73%。理论结果与验证结果基本一致,表明此方法是可行的。同时,从优化模型中可以看出人工土组成与湿干比存在交互作用。

Abstract: In this paper,the Artificial Rapid Infiltration System (ARI) was simulated under laboratory conditions,and the main designed parameters including the component of artificial soil (quartzite/soil) and running circle (flooding time and flooding time/drying time) for the highest removal rate of COD were optimized. The stable removal rate of COD was obtained by the reciprocal equation method,and the model of multi-linear regression equation was established by stepwise regressive method.The optimizing parameters of ARI were x1 (quartzite/soil)=1.073,x2 (flooding time)=4 h,and x3 (flooding time/drying time) =1/8,and the highest theoretical removal rate of COD was 84.73%,which was accordant with the practical value,indicating that the method was feasible.The model also suggested that there was an interaction between the component of artificial soil and the flooding time /drying time.
