生物滞留槽快速设计方法及实例研究
Rapid design and example research on bioretention groove
摘要
Abstract
In order to facilitate the application of bioretention technology in the construction of sponge city,the confluence ratio rapid algorithm is proposed as a kind of bioretention groove design method.This method is based on the principle of water balance,considering the influence of such factors as rainfall,rainfall duration,underlying surface types,bioretention surface storage layer depth,fillers permeability and water storage properties,vegetation density on the regulation effects of bioretention groove,to avoid the complex calculation and design.A set of bioretention grooves is designed and built by this method.The actual operation results show that the road runoff regulation effect of the bioretention groove is of significance.The runoff reduction rates of medium and small rainfall events are maintained at more than 80％,with the main pollutant load reduction rates greater than 85 ％.It also indicates that the confluence ratio rapid algorithm for bioretention design is more simple and effective.关键词
