Description
Technical field
The present invention relates to sponge city technical fields, and in particular to a kind of sponge urban rainwater processing system.
Background technique
Sponge city is new generation of city storm water man- agement concept, refers to that city is adapting to environmental change and reply rainwater band
Natural calamity come etc. has good " elasticity ", also referred to as " water elasticity city ".International term is " low shadow
Ring the building of exploitation storm-water system ".Water suction, water storage, infiltration, water purification when raining by the water of storage " release " and are subject to benefit when needing
With.The retention of sponge city initial rainwater using with later period rain infiltration is widely studied in sponge urban construction about rainwater
Processing project.
Sponge city is built, first has to torsion idea, traditional cities construction mode is hard surface everywhere.Whenever heavy rain,
Pipe duct is relied primarily on, for " grey " facility such as pumping plant to drain, controlling with " quickly excluding " and " end concentration " is that main planning is set
Meter theory often results in and meets rain flooded, drought and waterlogging racing.Sponge urban construction is then emphasized preferentially to utilize grass planting ditch, seepage brick, rainwater
Garden, sunk type greenery patches etc. " green " measure carrys out tissue draining, is main planning with " slow row's sustained release " and " source dispersion " control
Design concept not only avoids flood, but also effectively has collected rainwater.But the rate of current rain processing system processing rainwater
It cannot ensure that waterlogging will not occur when encountering heavy rain, and cannot effective secondary use to the rainwater of collection.Therefore, it is necessary to
It is proposed a kind of new technical solution.
Summary of the invention
The present invention proposes a kind of sponge urban rainwater processing system, solves the rate of processing rainwater of the existing technology
It is low, to the rainwater of collection cannot effective secondary use the problem of.
To achieve the goals above, the technical scheme of the present invention is realized as follows: a kind of sponge urban rainwater processing system
System, including vegetable layer, soil horizon, sand stone layer, water collection chamber and processing chamber, the vegetable layer, soil horizon, sand stone layer and water collection chamber by
It is set gradually under, the first overflow ducts and the second overflow ducts is respectively equipped on the upside side wall of the water collection chamber, it is described
The height of first overflow ducts be higher than second overflow ducts height, the water collection chamber by first overflow ducts with
Municipal drainage pipeline is connected, and the water collection chamber is connected by second overflow ducts with the processing chamber, described to catchment
Chamber is also communicated with the first water supply component to elevate above the soil, and the processing chamber passes through the second water supply component and production and living waterpipe
It is connected.
Preferably, the soil horizon is made of spaced blocky soil.
Preferably, the spacing between adjacent blocky soil is 0.5-0.1cm.
Preferably, the spacing between adjacent blocky soil is 0.3cm.
Preferably, the sand stone layer from top to bottom includes fine sand layer, gravel layer, metalling.
Preferably, first water supply component includes the first aqueduct, the first elevator pump, the second aqueduct and spray head,
One end of first aqueduct is protruded into the water collection chamber, the other end of first aqueduct and first elevator pump
Input terminal is connected, and the output end of first elevator pump is connected with one end of second aqueduct, second aqueduct
The other end protrudes into ground, and the spray head is mounted on the other end of the second aqueduct.
Preferably, second water supply component includes third aqueduct, the second elevator pump and the 4th aqueduct, and described
One end of three aqueducts is protruded into the processing chamber, the input terminal of the other end of the third aqueduct and second elevator pump
It is connected, the output end of second elevator pump is connected with one end of the 4th aqueduct, the other end of the 4th aqueduct
It is connected with production and living with waterpipe.
Compared with prior art, the present invention has an advantage that a kind of sponge urban rainwater processing system proposed by the present invention
System when encountering heavy rain, rainwater along vegetable layer, soil horizon, sand stone layer rapid osmotic into water collection chamber, in water collection chamber rapidly
Aggregation, it is excessive when the water aggregation in water collection chamber, it the second overflow ducts can be first passed through flows into and carry out purified treatment in processing chamber,
The water for penetrating into water collection chamber further increases, and rainwater can flow into municipal drainage pipeline by the first overflow ducts, prevents water collection chamber
After being inside full of, rainwater can not permeate again, and the rate of processing rainwater is caused to reduce, and rainwater can directly supply water by first
Component is delivered on ground for watering flowers, pouring green plant, and treated, and rainwater can be used as production and living water, carry out effective
Utilization again.Therefore, compared with prior art, the present invention has the rate of processing rainwater high, effective to the rainwater energy of collection
The advantages of secondary use.
