Description
Technical field
The utility model relates to environmental engineering Sewage treatment systems, is specifically related to a kind of artificial swamp for the treatment of city rainfall runoff.
Background technology
Urban ground mostly is watertightness, therefore after larger rainfall, just runoff can be produced, its flow is also corresponding larger, simultaneously to be mingled with the various pollutents from air, ground in runoff, and concentration is higher, initial stage process is carried out to it, the impact of runoff on water quality such as river, lake and underground water can be reduced.
Through the rainwater of artificial wetland treatment, can be used on afforestation, urban road sprays and multiple landscape water aspect, can saving water resource greatly.At present, Artificial Wetland Techniques is mainly used in dirty (giving up) water treatment aspect, utilizes the investigation and application of its process urban rainfall runoff relatively less.
The filler part of constructed wetland device is in the past all single, and such as flyash filler, easily blocks, and this can make current in the constricted flow of constructed wetland device inside, thus affects the decontamination effect improving of artificial swamp, reduces its clearance.
Utility model content
The technical problems to be solved in the utility model is that common Performance of Constructed Wetlands Substrates is single, and decontamination effect improving is poor, for solving the problem, provides a kind of artificial swamp for the treatment of city rainfall runoff.
The purpose of this utility model realizes in the following manner:
For the treatment of the artificial swamp of city rainfall runoff, described artificial swamp comprises water-in, water outlet and constructed wetland bed body, water-in and water outlet are positioned at the both sides of constructed wetland bed body, constructed wetland bed body is followed successively by waterplant, pedosphere, mixed filler layer, gravel bed, pebbles layer from top to bottom, constructed wetland bed body is also provided with ventpipe and crosses water baffle plate.
Described waterplant is at least one in reed, cattail, Canna generalis Bailey three, and the Planting pattern of waterplant is 12 ~ 15 Zhu/㎡.
Described mixed filler layer is made up of blast furnace slag, flyash and zeolite, and three by volume 1:1:1 is equipped with.
The thickness of described mixed filler layer, gravel bed, pebbles layer is all 300mm, and edaphic thickness is 300 ~ 400mm.
Described constructed wetland bed body is positioned at below earth's surface, and the both sides, front and back of constructed wetland bed body and below are brick or steel and concrete structure.
Described crosses water height of baffle plate higher than pedosphere upper surface 5cm ~ 15cm, crosses water baffle plate and is divided into top to have aperture and bottom
Have aperture two kinds, cross water baffle plate for two kinds and alternately arrange successively from water-in to water outlet, two distances crossed between water baffle plate are 1.5m ~ 3m.
When from artificial wetland effluent mouth nearest cross water baffle plate be top open foraminate cross water baffle plate time, constructed wetland bed body lower end is provided with rising pipe, and rising pipe is provided with valve.
Described ventpipe outside surface is covered with aperture or the outside surface that contacts with constructed wetland bed body is covered with aperture.
Relative to prior art, the utility model adopts multiple packing layer, and the particle diameter of packing layer is different, adopted water baffle plate, add duration of contact and the contact area of sewage and filler, more effective performance detergent power of the present utility model, enhances the detergent power of artificial swamp.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that foraminate water baffle plate is excessively opened on top.
Fig. 3 is that foraminate water baffle plate is excessively opened in bottom.
Wherein, 1 is ventpipe; 2 was water baffle plates; 3 is waterplant; 4 is pedospheres; 5 is mixed filler layers; 6 is gravel beds; 7 is pebbles layers; 8 valves.
Embodiment
As shown in Figure 1, the utility model is for the treatment of the artificial swamp of city rainfall runoff, described artificial swamp comprises water-in, water outlet and constructed wetland bed body, water-in and water outlet are positioned at the both sides of constructed wetland bed body, constructed wetland bed body is followed successively by waterplant 3, pedosphere 4, mixed filler layer 5, gravel bed 6, pebbles layer 7 from top to bottom, constructed wetland bed body is also provided with ventpipe 1 and crosses water baffle plate 2.Described waterplant 3 is at least one in reed, cattail, Canna generalis Bailey three, and the Planting pattern of waterplant 3 is 12 ~ 15 Zhu/㎡.Described mixed filler layer 5 is made up of blast furnace slag, flyash and zeolite, and three by volume 1:1:1 is equipped with.The thickness of described mixed filler layer 5, gravel bed, 6 pebbles layers 7 is all 300mm, and the thickness of pedosphere 4 is 300 ~ 400mm.Described constructed wetland bed body is positioned at below earth's surface, and the both sides, front and back of constructed wetland bed body and below are brick or steel and concrete structure.Described crosses water baffle plate 2 higher than pedosphere 4 upper surface 5cm ~ 15cm, cross water baffle plate 2 to be divided into top to open foraminately crossing water baffle plate 2(as shown in Figure 2) and bottom open foraminate mistake water baffle plate 2(as shown in Figure 3), both alternately arrange successively from water-in to water outlet, such sewage can form serpentine flowing in the bed body of artificial swamp, increase duration of contact and the contact area of artificial swamp and sewage, increase the detergent power of artificial swamp.Two distances crossed between water baffle plate are 1.5m ~ 3m, can 1.5m, 1.6m, 1.7m, 1.8m, 1.9m, 2.0m, 2.1m, 2.2m, 2.3m, 2.4m, 2.5m, 2.6m, 2.7m, 2.8m, 2.9m, 3.0m be selected in actual applications, also can determine according to concrete practical situation.When the excessively water baffle plate 2 nearest from artificial wetland effluent mouth opens foraminate water baffle plate 2 excessively for top, constructed wetland bed body lower end is provided with rising pipe, rising pipe is provided with valve 8.Described ventpipe 1 outside surface is covered with aperture or the outside surface that contacts with constructed wetland bed body is covered with aperture.
The beneficial effects of the utility model: the probability reducing artificial swamp blocking, the same position of artificial swamp is all that multiple filler and plant jointly play and act on, and makes the clearance of artificial swamp to pollutent reach higher level.Through the rainwater of artificial wetland treatment, can be used in road and spray, the multiple aspect such as afforestation, has saved water resources greatly.By the utility model, city water resource katatonosis can be alleviated greatly, more fully, reasonably utilize resource, the strategic requirement of response Sustainable development.
