Analysis of the Effect of Different Soil Types on the Storage and Pollution Control of Urban Road Rainwater in Depressed Green Spaces
This paper studied the removal effects of three groups of experimental devices made of red soil,yellow-brown soil,and black soil on COD(Chemical oxygen demand),NH4+-N(Total nitrogen),PO43--P(Total phosphorus),and SS(Total suspended solids).The experimental results showed that the treatment effect of red soil on COD and NH4+-N was slightly better than the other two types of soil.However,there was no significant difference among the three soils in the removal of PO43--P.The removal effect of yellow-brown soil on SS was slightly higher,reaching 88.79％.Therefore,it can be concluded that the influencing factors deter-mining the soil type of the concave green space are not solely dependent on the soil's own pollution inter-ception degree,but also on the convenience of soil acquisition during engineering construction and the suit-ability of the soil for the growth of green space plants.
