摘要
填料的组成及配比是生物滞留系统功能发挥的关键因素,但当前相关的配比理论和方法还不完善。建立一种以细砂为主体基质的填料配比方法,完善砂基填料配比过程,具有一定的理论和实践价值,依据生物滞留池填料承载的主要功能,阐述了排空时间和有机质含量两个关键参数的指标内涵,论述了指标的作用与功能、指标之间的相互关系及其取值范围,并基于两个指标的约束条件,提出了一种砂基填料的配比方法。基于方法构建的砂基填料生物滞留池,总体效能较好,进一步证明了配比方法的适用性。基于理论计算和试验验证探讨了有机质和渗透系数这两个关键指标的平衡问题。
The composition and proportion of fillers are the key factors for the function of bioretention system,and the current relevant matching theories and methods are not perfection.It is a great practical significance to establish a proportion method with fine sand as the main matrix.According to the basic functions of bioretention fillers,the connotation of two key indexes,emptying time and organic matter content,are introduced in detail.The function,the relationship and their value range of the two indexes are discussed.A proportioning method of bioretention fillers is proposed based on the two constraints of organic matter content and emptying time.The overall performance of the bioretention system based on the proportioning scheme is excellent,which further proves the applicability of the proportioning method.
