Description

A kind of community rainwater-collecting, purification and reusing integral system
Technical field
The utility model belongs to rainwater treatment and reuse technical field, is specifically related to a kind of community rainwater-collecting, purification and reusing integral system.
Background technology
In the last few years, due to the development of urbanization, the hard surface in city and roofing more came all many, caused the minimizing of urban green space.When heavy showers occurred, rainwater entered rapidly storm sewer through collecting, and to urban sewerage and drainage system, had brought huge pressure on the one hand, and on the other hand, rainwater is a kind of resource of preciousness, and directly entering storm sewer is the significant wastage to fresh water.
The utility model content
For above-mentioned problem, technical problem to be solved in the utility model just is to provide a kind of community rainwater-collecting, purification and reusing integral system, and it can alleviate the pressure of storm runoff to urban sewerage and drainage system, again can be by the Rainwater Resources reuse.
Technical problem to be solved in the utility model is to realize by such technical scheme, it includes Green Roof, gutter filtration system and intensive treatment pond, Green Roof connects the intensive treatment pond by rainwater down pipe, and the gutter filtration system is through braiding channel or pipeline communication intensive treatment pond.
Owing to having adopted technique scheme, when heavy rain, rainwater on road is by the preliminary treatment of gutter filtration system, rainwater on roof is through the purification of plants and soil on Green Roof, rainwater is pooled to the intensive treatment pond from gutter filtration system and Green Roof, through intensive treatment, the part rain-water accumulating is stored away again.Like this, reduced the runoff coefficient of community on the one hand, thereby reduced the pressure of Storm Sewer Network, the rainwater of collecting on the other hand stores after treatment, realizes the Rainwater Resources reuse.
The utlity model has following advantage: the runoff coefficient that can reduce community, thereby reduce the pressure to Storm Sewer Network, can realize the Rainwater Resources reuse again, storing can be for pouring greenbelt in little residential region flowers and plants or for rinsing the community pavement usage at the rainwater in intensive treatment pond.
The accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of road ditch filtration system in Fig. 1;
Fig. 3 is the structural representation on Fig. 1 Green roof;
Fig. 4 is the structural representation in intensive treatment pond in Fig. 1.
In figure: 1. Green Roof; 2. road; 3. gutter filtration system; 4. intensive treatment pond; 5. rain grid made; 6. cobble; 7. gravel; 8. braiding channel; 9. vegetable layer; 10. synthetic native; 11. layer of gravel; 12. deck; 13. roof drain; 14. grid; 15. filter material layer; 16. reservoir; 17. rainwater down pipe.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the utility model includes Green Roof 1, gutter filtration system 3 and intensive treatment pond 4, and Green Roof 1 connects intensive treatment pond 4 by rainwater down pipe 17, and gutter filtration system 3 is through braiding channel or pipeline communication intensive treatment pond 4.
When heavy rain, rainwater on road 2 is by 3 preliminary treatments of gutter filtration system, and the rainwater on roof is through the purification of plants and soil on Green Roof 1, and rainwater is pooled to intensive treatment pond 4 from gutter filtration system 3 and Green Roof 1, through intensive treatment, the part rain-water accumulating is stored away again.
As shown in Figure 2, gutter filtration system 3 is provided with rain grid made 5, cobble layer 6, layer of gravel 7 and braiding channel 8 from top to bottom, leaves certain space between rain grid made 5 and cobble layer 6.Hour, runoff imports braiding channel 8 by holding back with the filtration of layer of gravel 7 of cobble layer 6 to the run-off converged when road 2, imports in intensive treatment pond 4 by braiding channel 8; When more, unnecessary runoff overflows in storm sewer by the space between rain grid made 5 and cobble layer 6, is discharged by urban sewerage and drainage system when road 2 runoffs.Filtration system 3 connects with also adopting pipeline being connected of intensive treatment pond 4.
As shown in Figure 3, Green Roof 1 is provided with vegetable layer 9, synthetic soil layer 10, layer of gravel 11 and deck 12 from top to bottom.When rainfall, rainwater is purified rainwater through filtration and the absorption of vegetable layer 9, synthetic soil layer 10 and layer of gravel 11, the pollutant be retained down is degraded under the effect of microorganism, by the root absorption of plant, rainwater after purification infiltrates roof drain 13 from layer of gravel 11, then imports intensive treatment pond 4 through rainwater down pipe 17.
As shown in Figure 1 and Figure 4, intensive treatment pond 4 comprises filtering area and reservoir 16, wherein filtering area has sedimentation basin and filter material layer 15, the outside of filtering area is sedimentation basin, the oral area of sedimentation basin is provided with grid 14, filtering area is filter material layer 15 towards a side of reservoir, and the weep hole of filter material layer 15 bottoms is communicated with reservoir 16.
Rainwater from the rainwater after 3 preliminary treatments of gutter filtration system and Green Roof 1 precipitates at sedimentation basin again through grid 14, rainwater after precipitation can be removed most suspended substances matter, the rainwater overflowed by sedimentation basin top flows to filter material layer 15, rainwater infiltrates from top to bottom in filter material layer 15, implement to filter, the weep hole through filter material layer 15 bottoms enters reservoir 16.
When heavy showers, as the water level in intensive treatment pond 4, arrive the water level of setting, unnecessary runoff overflows in urban sewerage and drainage system or greenery patches by bleed off pipe.
Grid 14 in intensive treatment pond 4 adopts 4-6 purpose fine fack or filter screen, sedimentation basin has sand deposition hopper, sedimentation basin and filter material layer 15 use plastic septums separate, the perforate of plastic septum top, the filtrate module in the sand deposition hopper in sedimentation basin and filter material layer 15 is all detachable, when the more need cleaning of sand setting, or filtrate is need change the time, the filtrate that all can manually module be proposed to cleaning or more renew, be provided with catch basin in reservoir 16, during for the reuse rainwater, places water pump.
In the utility model, road 2 ponding import gutter filtration systems 3, make rainwater obtain preliminary treatment under the effects such as the filtration of gutter filtration system 3, absorption, ion-exchange; Roof rain water is purified under the physical-chemical of Green Roof 1-biological-ecological comprehensive function; Both direction imports intensive treatment pond 4, in intensive treatment pond 4 precipitation, filter, and finally store in the reservoir 16 of strengthening and processing device for water spill greenery patches and rinse road used.The integral system of community rainwater-collecting, purification and reuse that the utility model is combined into by Green Roof 1, gutter filtration system 3 and intensive treatment pond 4, can make segment path ponding in community and from the rainwater purification on roof and store, play the effect of regulating rain mighty torrent amount, reducing the community runoff coefficient, rainwater after process in the intensive treatment pond can reuse, plays the effect of Rainwater Resources.
