Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses greenbelt rain sewage treatment system.
Referring to fig. 1, a green belt rain sewage treatment system comprises a green belt body 1, wherein the green belt body 1 is arranged on a roadbed 14, the green belt body 1 comprises a vegetation layer 11, the vegetation layer 11 is filled in the green belt body 1, and in the present embodiment, the vegetation layer 11 is planting soil. Meanwhile, the inner bottom wall of the green belt body 1, namely the bottom of the planting soil, is provided with the permeable cloth 13, the inner bottom wall of the green belt body 1 is provided with the first drainage hole 12, and the first water storage tank 2 is installed at the outlet of the first drainage hole 12. In addition, in order to store rainwater in the first water storage tank 2 and absorb the rainwater by the green belt body 1 again for use, a cotton rope 21 is pre-buried in the planting soil, the cotton rope 21 penetrates through the bottom of the green belt body 1 and extends into the first water storage tank 2,
when rainwater gets into greenbelt body 1, the rainwater can permeate the interior of greenbelt body 1 through the planting soil in the greenbelt body 1, some rainwater is absorbed by the vegetation of planting on the planting soil afterwards, another part rainwater is discharged first water storage box 2 from the wash port through the cloth 13 that permeates water, and simultaneously, rainwater in first water storage box 2 can get into the planting soil from first water storage box 2 again through cotton rope 21's absorption effect, thereby for the vegetation on the planting soil provides the required moisture of growth, and then reduce the city artificial water resource of greenbelt body 1 consumption.
In addition, in order to increase the water resource reserve of the first water storage tank 2, in this embodiment, the treatment tank 36 is dug at the bottom of the green belt body 1, and the first water storage tank 2 is located in the treatment tank 36, in this embodiment, the outer edge of the treatment tank 36 is formed by a waterproof wall, which can effectively reduce the water body leaking from the treatment tank 36. Meanwhile, drainage ditches 31 are dug at two sides of the green belt body 1, rainwater grates 311 are installed at the tops of the drainage ditches 31, rainwater falling on the roadbeds 14 at two sides of the green belt body 1 can enter the drainage ditches 31 through the rainwater grates 311, a connecting pipe 32 is installed at one side of the drainage ditches 31 close to the green belt body 1, and the connecting pipe 32 is horizontally inserted into the waterproof wall and communicated with the inside of the treatment tank 36.
In order to drain the rainwater collected in the drainage ditch 31 into the disposal basin 36 as quickly as possible, the bottom of the drainage ditch 31 is inclined, and specifically, the side of the drainage ditch 31 close to the connection pipe 32 is lower than the side of the drainage ditch 31 far from the connection pipe 32, so that the rainwater collected in the drainage ditch 31 can automatically flow toward the connection pipe 32 under the action of gravity.
In addition, since the rainwater on the roadbed 14 may carry a large amount of impurities, such as leaves and sand, and the rainwater on the roadbed 14 is also polluted by the exhaust gas discharged from the vehicle, in order to purify the rainwater collected from the roadbed 14 by the drainage hook, in the present embodiment, the second water storage tank 4 is installed at the bottom of the treatment tank 36, the second drainage hole 37 is opened at the top of the second water storage tank 4, and the filter layer is filled at the top of the second drainage hole 37.
Specifically, the filter layer includes coarse sand layer 33, fine sand layer 34 and activated carbon layer 35, and coarse sand layer 33, fine sand layer 34 and activated carbon layer 35 fill in proper order in the top of second water storage box 4 from last to bottom, and coarse sand layer 33 leaves one section space with the bottom reservation of first water storage box 2 to increase coarse sand layer 33 and the area of contact of draining into the rainwater from connecting pipe 32, thereby improve the infiltration efficiency of rainwater.
The rainwater that enters into in the treatment tank 36 from connecting pipe 32 firstly permeates coarse sand layer 33 below connecting pipe 32, can effectively filter the large granule impurity in the rainwater through coarse sand layer 33, for example, the incomplete leaf of broken, the fine sand layer 34 is further permeated to the rainwater afterwards, can filter most little granule impurity through fine sand layer 34, for example gravel, and the rainwater permeates activated carbon layer 35 at last, and activated carbon can adsorb most heavy metal compound of sneaking into in the rainwater.
After the filtration of filter layer, the rainwater after the purification is more fit for the irrigation to greenbelt body 1, has reduced the growth influence of the pollutant in the rainwater to the vegetation simultaneously. The filtered rainwater flows into the second water storage tank 4 through the second drain hole 37 and is stored therein. Install water pump 41 and liquid level detector 43 in second water storage tank 4, and liquid level detector 43 electric connection is on water pump 41, when liquid level detector 43 detects the water level in second water storage tank 4 and surpasses predetermined height, can automatic start water pump 41, because the structure and the principle of liquid level detector 43 are prior art, do not describe here any more.
Meanwhile, a return pipe 42 is connected to the output end of the water pump 41, the return pipe 42 sequentially penetrates through the top wall and the filter layer of the second water storage tank 4 from bottom to top, and then the return pipe 42 penetrates through the side wall of the first water storage tank 2 to be connected with the inside of the first water storage tank 2, so that rainwater stored in the second water storage tank 4 can be supplemented into the first water storage tank 2 through the return pipe 42 when the water pump 41 is started, and irrigation is facilitated for the green belt body 1.
In addition, thereby flow backward and enter into the greenbelt body 1 for preventing the too much rainwater in the first water storage box 2 to cause the rotten moldy problem of vegetation root system, in this embodiment, overflow hole 22 has been seted up to the lateral wall upper end of first water storage box 2, and overflow hole 22 is linked together with treatment tank 36.
The implementation principle of a green belt rain sewage treatment system in the embodiment of the application is as follows:
when the urban rainfall, the rainwater falls into the roadbed 14 and the green belt body 1 on the roadbed 14, wherein the rainwater falling into the green belt body 1 seeps into the vegetation layer 11, and part of the rainwater which is not absorbed by the vegetation layer 11 enters the first drainage hole 12 through the water permeable cloth 13 and is then collected by the first water storage tank 2.
In addition, the rainwater falling on the roadbed 14 flows into the drainage ditch 31 through the rainwater grate 311, enters the treatment tank 36 through the connecting pipe 32 under the action of gravity, is filtered by the coarse sand layer 33, the fine sand layer 34 and the activated carbon layer 35 in sequence, and finally enters the second water storage tank 4 through the second drainage hole 37.
When the water level in the second water storage tank 4 reaches a predetermined height, the liquid level detector 43 sends a start signal to the water pump 41, after the water pump 41 is started, the water in the second water storage tank 4 flows into the first water storage tank 2 through the return pipe 42, and the excess water in the first water storage tank 2 is discharged out of the first water storage tank 2 through the overflow hole 22.
When the city lacks rainfall, the rainwater in the first water storage tank 2 enters into the vegetation layer 11 of the green belt body 1 through the cotton rope 21, thereby being absorbed and utilized by the vegetation root system planted in the vegetation layer 11.
The above are all preferred embodiments of the present application, and the present embodiment is only explained for the present application, and the protection scope of the present application is not limited by this, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
