Utility model content
For deficiency above-mentioned in the prior art, the utility model provides a kind of sponge urban sewage treating device, this dressInfiltration can be carried out purified treatment by putting, then water is carried out into road surface flushing or further after purification as life useWater.
In order to achieve the above object, the solution of the utility model use is：Sponge urban sewage treating device, includingGround body and the water treatment facilities being arranged on below the body of ground, ground body include roadside body and meadow body, roadsideCurb is provided between body and meadow body；Road surface body include be sequentially distributed from top to bottom pervious asphalt concrete layer,Permeable base course, tamping road bed layer, meadow body include be sequentially distributed from top to bottom layer of plants, dirt bed, the permeable base in meadowLayer and meadow compacting basic unit；Permeable base course bottom surface, meadow porous base course bottom surface tilt to curb direction.
It is provided with below curb for the water of permeable base course bottom and meadow pervious bed bottom to be guided to water processCollector pipe in device；Water treatment facilities include waterproof case, the filter being sequentially connected, the first water pump, the first water tank,Second water pump and successively filtering and sterilizing device, the second water tank, the 3rd water pump of pipe connection, the water side connection of the second water pumpThere is the first outlet pipe, the first outlet pipe is drawn from waterproof case and leads to pervious asphalt concrete layer upper surface, the first outlet pipeWater side be fixedly connected with rotation shower nozzle；It is provided with three-way pipe between the connecting line of first water pump and the first water tank, threeSiphunculus is connected with filtering and sterilizing device pipe.
Preferably, road surface waterproof layer, meadow porous base course and meadow are provided between permeable base course and tamping road bed layerMeadow waterproof layer is provided between compacting basic unit.
Preferably, curb both sides are provided with anti-fall boss.
The beneficial effects of the utility model are that rainwater infiltrates into permeable base course from pervious asphalt concrete layer on the groundIt is interior, infiltrated into from dirt bed in the porous base course of meadow, rainwater enters in filter after collector pipe again to be filtered, then passes through theWater after filtering is delivered to the first storage tank by one water pump, and water, it is necessary to when clearing up road surface, then starts and turned in the first storage tank inner storage tankDynamic shower nozzle, rotate shower nozzle and the dust of pervious asphalt concrete layer is rinsed, the muddy water after flushing enters in dirt bed, passes throughWater after the further disinfection filtering of filtering and sterilizing device can introduce waterworks as civil plantation water, thus, sponge cityCity collects the water resource come and is fully used, and so as to reorganize urban water supply system, conventional drainage systems are risenTo Reduction of Students' Study Load and supplementary function, the effect of city in itself has been played to a greater degree.

Embodiment
The utility model is further described below in conjunction with accompanying drawing：
Referring to the drawings 1, the utility model provides a kind of sponge urban sewage treating device, including ground body and is arranged onWater treatment facilities below the body of ground, ground body include roadside body and meadow body, roadside body and meadow body itBetween be provided with curb 10；Road surface body include be sequentially distributed from top to bottom pervious asphalt concrete layer 21, permeable base course 22,Tamping road bed layer 23, meadow body include be sequentially distributed from top to bottom layer of plants 31, dirt bed 41, the and of meadow porous base course 33Tamp basic unit 34 in meadow；The permeable bottom surface of base course 22, the bottom surface of meadow porous base course 33 tilt to the direction of curb 10.
The lower section of curb 10 is provided with for the water of the permeable bottom of base course 22 and meadow pervious bed bottom to be guided to waterCollector pipe 41 in processing unit；Water treatment facilities includes waterproof case 42, the filter 43 being sequentially connected, the first water pump44th, the first water tank 45, the second water pump 46 and successively pipe connection filtering and sterilizing device 51, the second water tank 52, the 3rd waterPump 53, the water side of the second water pump 46 are connected with the first outlet pipe 47, and the first outlet pipe 47 is drawn and led to from waterproof case 42The upper surface of pervious asphalt concrete layer 21, the water side of the first outlet pipe 47, which is fixedly connected with, rotates shower nozzle 49；First water pump 44Three-way pipe 48 is provided between the connecting line of the first water tank 45, three-way pipe 48 is connected with the pipe of filtering and sterilizing device 51, and threeIt is dual-purpose that siphunculus 48, which realizes the moisture for carrying out present apparatus collection, improves service efficiency, increase uses function.
