Water storage module, water storage module are connected to reservoir, water storage module and reservoir can a large amount of rainwater of accumulation, cope with larger
Water storage, purification demand；And the water in water storage module and/or reservoir is sprayed by the water surface by fountain apparatus and drops into flower again
Garden main body carries out circulation diafiltration, purification, the pollutant in rainwater is sufficiently removed；When water in water storage module enters reservoir,
By the adsorption treatment of heavy metal adsorption device, the heavy metal contaminants in water can be effectively removed.
Rainwater enters after coating plants soil layer, removes one using the percolation of the absorption cleaning of plant, soil
Dividing pollutant, hand-stuff layer can remove the pollutants such as organic pollutant and the nitrogen phosphorus in rainwater using the microorganism of inoculation,
Rainwater enters sand stone layer and gravel layer after hand-stuff layer, eventually enters into water storage module.At this point, rainwater is by garden main body
It is primary diafiltration, purification process.
Preferably, the garden main body is additionally provided with for the rainwater for having little time lower infiltration on the coating to be introduced the storage
The overflow pipe of pond or other garden main bodys.By setting overflow pipe, excessive rainfall in the main body of garden can be discharged in time,
Plant is prevented to be submerged.
It is further preferred that the overflow pipe is equipped with filter screen.By filter screen, prevent supratectal bulky grain pollutant from spreading
To reservoir or other garden main bodys.
Preferably, the plant for planting soil layer be ciliate desert-grass, it is Sedum alfredii Hance, Alyssum, duckweed, gold leaf Scirpus tabernaemontani, eel grass, black
One or more of the red bog pondweed of algae, watermifoil, water caltrop, castor, p.malaianus.Above-mentioned plant can be used in absorbing in water
Heavy metal, and be resistance to water-wet plant.
Preferably, the hand-stuff layer uses charcoal.
Preferably, the reservoir is equipped with the water level pipe for preventing the water storage pool water level to be higher than water storage module upper end,
The lower end of the water level pipe is connect with city planting ductwork.When the water level in reservoir is higher than the upper end of water level pipe, in reservoir
Water can drain from water level pipe, and water level will not continue to rise.
Preferably, the fountain apparatus includes the water pump and spray head connected by pipeline.Water pump can by water storage module and/
Or the water in reservoir is promoted and is pressurizeed, and is gone out subsequently into nozzle rear-spraying.
Preferably, the Rain Garden further includes for providing the device of solar generating of electric energy to the fountain apparatus.
By solar powered, the energy has effectively been saved.
Preferably, the heavy metal adsorption device is filled with the mixture of sodium titanate nanofiber and active carbon.
Compared with prior art, the utility model has the beneficial effects that
The Rain Garden of the circulating purification of the utility model utilizes the catharsis of garden main body, using the storage of garden main body
Water module and reservoir collect a large amount of rainwater, then the water in water storage module and/or reservoir is sprayed the water surface by fountain apparatus
It is dropped into the main body of garden again, carries out circulating purification, the pollutant in rainwater can sufficiently be removed.Fountain apparatus can also improve
Air quality, improves amenity sense, beautifies the environment aeration running water.
