A storage wetland system for treating parking lot rainwater and adjusting microclimate

Abstract

The invention provides a flow storage wetland system for treating parking lot rainwater and adjusting microclimate. Parking spaces of a parking lot are separated by intersection of driveways and interval zones, grass ditch wetlands and underground channels are separated by slow flow partition plates on the interval zones, the terrain from the grass ditch wetlands to the underground channels is elevated, the underground channels are close to the driveways and communicated with channels at the lower ends of the driveways, the terrain of the channels at the lower ends of the driveways is elevated, and low ends of the channels at the lower ends of the driveways are communicated with a front ecological pond. Polluted water is preliminarily treated by the aid of the grass ditch wetlands, the preliminarily treated water is delivered to the front ecological pond for storage by the elevated terrain of the system and then filtered by an ecological filter bed and finally enters a clean water tank for storage by an automatic clean water collection device, and the problems of pollution, rainwater resource waste, dry climate and the like caused by rainwater runoff of the parking lot.

Description

technical field [0001] The invention relates to a storage wetland system, in particular to a storage wetland system for treating rainwater in a parking lot and adjusting microclimate, and belongs to the technical field of environmental protection engineering and water treatment. Background technique [0002] In recent years, the area of ​​the parking lot has greatly increased along with the increase of the number of motor vehicles. The traditional concrete parking lot forms thermal pollution and low greening rate. In summer, vehicles are exposed to the sun, resulting in high temperature inside the vehicle. In addition to the negative impact of temperature, parking lots on hard roads also have pollution such as engine oil, exhaust gas, dust, etc., which are mainly caused by vehicle tire wear, brakes, fuel or lubricating oil leakage, etc. The pollution components include solid substances, heavy metals, Oils and fats and toxic organics. The impermeable ground causes these pol...

AI Technical Summary

Problems solved by technology

The impermeable ground makes these pollutants gradually washed up or dissolved during the rainfall, and flow directly to the sewer, and a large amount of rainwater resources cannot be recycled and reused
