Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example 1

Referring to fig. 1 to 3, an artificial wetland structure includes a first water-separating tank 1, a first soil layer 3, a first water outlet pipe 5, a second water-separating tank 6 and a second soil layer 7, wherein a water inlet pipe 2 is disposed on the left side of the first water-separating tank 1, the water inlet pipe 2 penetrates through the left wall of the first water-separating tank 1 and extends into the first water-separating tank 1, a first gravel layer 4 is filled in the first water-separating tank 1, the first soil layer 3 is disposed above the first gravel layer 4, the first water outlet pipe 5 penetrates through the right wall of the first water-separating tank 1 and the left wall of the second water-separating tank 6 and extends into the second water-separating tank 6, the second water-separating tank 6 is connected to the first water-separating tank 1, a second gravel layer 8 is filled in the second water-separating tank 6, and the second soil layer 7 is disposed above the second gravel layer 8.

The inner surface of first outlet pipe 5 has cup jointed out water inner tube 10, goes out through detachable mode fixed connection between water inner tube 10 and the first outlet pipe 5, play water inner tube 10 is including filtering barrier 11, stirring vane 13 and connecting piece 14, filter barrier 11 and the internal surface fixed connection of play water inner tube 10, stirring vane 13 passes through bearing swing joint with connecting piece 14, connecting piece 14 passes through connecting rod 12 and the internal surface fixed connection of play water inner tube 10.

Further, the inside of first soil horizon 3 and second soil horizon 7 all is equipped with aquatic plant and its root runs through the soil horizon and extends to its below, the lower floor stone of first metalling 4 is great for the upper rock, and sewage treatment's leading mode is exactly through aquatic plant, and the metalling can support soil on the one hand, and on the other hand is convenient for the circulation of water.

Because the volume of second water proof groove 6 is less, and the sewage that can handle is less, so in order to raise the efficiency, the bottom of second water proof groove 6 is equipped with second outlet pipe 9, second outlet pipe 9 is total two and is located the front and the back of second water proof groove 6 respectively, sets up two second outlet pipes 9, and two sides play water on the one hand improves work efficiency, and on the other hand if one of them outlet pipe that second water proof groove 6 appears blocks up, can follow another outlet pipe and go out water, is convenient for maintain the change to the outlet pipe that blocks up.

In order to prevent the bearing from rusting when contacting water and causing the bearing to be incapable of rotating, thereby influencing the movement of the stirring blade 13, not only the function of dredging the bearing is not realized, but also the smooth water flow is influenced, the bearing between the connecting piece 14 and the stirring blade 13 has a water-resisting design.

Furthermore, the loophole of the filtering barrier net 11 is smaller than the broken stone of the first gravel layer 4, and the filtering barrier net 11 is used for intercepting the broken stone, so that the broken stone is prevented from entering the water outlet inner pipe 10 along with water flow, and the stirring blade 13 is damaged or clamped, so that the normal use is influenced.

Furthermore, the height of the left wall of the first water separation tank 1 is higher than that of the right wall of the first water separation tank, the first water separation tank 1 has two water outlet modes, one mode is water outlet through the first water outlet pipe 5, the other mode is water outlet through the top end of the right wall, and the water in the tank can overflow from the top end of the right wall after being full.

Example 2

The working mode of the water outlet inner pipe 10 in the embodiment 1 is described in the present embodiment, which specifically includes the following steps: under the normal condition, after sewage treatment, discharge from first outlet pipe 5, filter barrier 11 and intercept the rubble, probably partial soil or mud gets into first outlet pipe 5 along with the rivers, when the rivers were through stirring vane 13, strike its surface and drive stirring vane 13 and rotate, pivoted stirring vane 13 can stir soil silt, make it disperse, form less volume, just so be difficult for blockking up, less debris are discharged to second water proof groove 6 from first outlet pipe 5, become the new soil of second water proof groove 6, also can regularly clear up, and is comparatively convenient, if take place under the condition of jam, can take out water outlet end of outlet pipe 10 from first outlet pipe 5, maintain and change, and it is comparatively convenient.

The utility model discloses a theory of operation is: when the device is used, sewage enters the first water separation tank 1 from the water inlet pipe 2, is purified by the aquatic plants, is discharged from the first water outlet pipe 5, is secondarily purified by the aquatic plants in the second water separation tank 6, and is finally discharged from the second water outlet pipe 9, if the first water separation tank 1 is blocked, the sewage can be discharged into the second water separation tank 6 in an overflowing mode, or can be directly introduced into the second water separation tank 6 for treatment, and after maintenance and replacement are well carried out, recovery is carried out.

Although the preferred embodiments of the present patent have been described in detail, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the knowledge of those skilled in the art.
