摘要
The present invention is a natural circulation type tree planter filtration system that reduces non-point pollution sources that occur on impervious surfaces in urban areas by utilizing urban infrastructure. It can be applied to regional design, and after installation of the facility, it reduces non-point pollutants generated in urban areas and roads, and peak flow and outflow through ground storage and soil storage rather than transferring the treated rainwater to the sewer. It relates to a natural circulation type tree pot filtration system with technology that reduces the volume and helps to solve the problem of groundwater depletion and prevent flood disasters. The composition of the invention consists of a wooden box, a filter medium, a water filling space, a planting space, vegetation soil gravel, and a drain hole. In the upper planting space, trees (street trees) and shrubs can be planted to create a natural urban landscape, and in the lower part, polluted rainwater stored in the supplementary space is supplied to the planted trees through a filtration filter and partly through vegetation soil. , it is a natural circulation type tree pot filtration system with a structure that circulates some underground. With this system, more rainwater can be returned to groundwater by connecting a rainwater retention device in areas where there is a lot of rainwater. It can be used by connecting the rainwater retention device to the wooden box with a rainwater connector. A planting space is placed on the upper part of the rainwater retention device to plant trees, etc., and it can be used as a flower bed. It is supplied, and a portion is sent to the rainwater box through the rainwater connection pipe and returned to street trees and groundwater. When the natural circulation type tree planter filtration system of the present invention is installed, there are effects such as flood prevention by removing non-point pollution sources of rainwater and reducing peak runoff.
