To realize the above-mentioned technical purpose, the following technical solution is employed for the utility model: the rainwater flower of high-efficient denitrification and dephosphorization
Garden, including foundation pit and positioned at the reservoir of bottom of foundation ditch；The foundation pit is enclosed by the permeable wall of surrounding and bottom；It is described
The top side of foundation pit is provided with water inlet pipe, and the bottom side of the reservoir is provided with outlet pipe；
Soil horizon, zeolite layer, active carbon layer and gravel layer are successively arranged in the foundation pit from top to bottom；It is set in the foundation pit
It is equipped with ventilation dosing overflow pipe, the soil horizon, the ventilation dosing overflow pipe are stretched out in the upper end of the ventilation dosing overflow pipe
Lower end sequentially pass through the soil horizon, zeolite layer, active carbon layer and gravel layer and stretch in the reservoir.
The permeable wall is paved by water-permeable brick as a preferred technical solution,.
It is equipped with lid sieve at the upper end tube nozzle of the ventilation dosing overflow pipe as a preferred technical solution, it is withered for intercepting
Branch fallen leaves enter overflow pipe.
The ventilation dosing overflow pipe is hollow steel pipe as a preferred technical solution,.
Several holes are offered on the tube wall of the hollow steel pipe as a preferred technical solution, hole adds for ventilating
Medicine.
Due to the adoption of the above technical scheme, the utility model has at least following the utility model has the advantages that according to the utility model
Rain Garden, rainwater penetrate into reservoir, the rainwater when rainfall is larger by permeable wall after plant and hypothallus filtration, purification
The dosing overflow pipe that can directly be ventilated flow to reservoir purification, cuts down rain peak run-off, reservoir rainwater can flow back through permeable wall
To top, efficient circulating water purification system is formed, efficiently removes the nitrogen phosphorus in rainwater.Drug energy in ventilation dosing overflow pipe
Enough degrading microorganisms enter modified substrate, promote the formation of matrix granule surface recombination biomembrane, enhance the activity of biomembrane, mention
Height constructs the microorganism-matrix system with pollutant strengthened purification effect, further strengthens to the detergent power of pollutant
The removal effect of water pollutant, the purification system combined by physics, a variety of methods of chemistry, biological respinse, have high efficiency,
Low cost, low-maintenance technology, and the advantages that do not limited by seasonal temperature.Rainwater is penetrated into arid season through permeable wall in reservoir
Rain Garden is that plant growth supplies water, it can also be used to be irrigated, carwash etc., effectively recycling rainwater resource.Garden top simultaneously
Plant can build green landscape and beautify the environment, and small investment, and construction is simple, and management service is convenient.
Detailed description of the invention
Following drawings are only intended to schematically illustrate and explain the present invention, does not limit the model of the utility model
It encloses.Wherein:
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is further described.In the following detailed description, only pass through
