Description

An annular radial artificial wetland

technical field

The utility model relates to the technical field of artificial wetlands, in particular to an annular radial artificial wetland.

Background technique

Artificial wetland sewage purification technology is a new sewage treatment process developed in the late 1970s. It is widely used in domestic sewage, surface water, non-point source pollution and other sewage treatment. It uses wetland plants, microorganisms, soil (fillers), etc. to remove pollutants in sewage through physical, chemical, and biological actions. It has the characteristics of large buffer capacity, good treatment effect, simple process, low investment, and low operation and management costs. It is a sewage treatment process integrating ecological and landscape features.

At present, during the use of constructed wetlands, due to the large amount of difficult-to-degrade substances in the sewage itself, coupled with long-term use, it will cause blockage of the water inlet pipe and the inside of the constructed wetland, which will seriously lead to the paralysis of the entire constructed wetland system, and the constructed wetland The outlet pipes are laid side by side at the bottom of the constructed wetland, which will cause problems such as slow drainage and low efficiency.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art, and provide an annular radial artificial wetland.

The utility model aims to solve the problems of clogging and low drainage efficiency of the water outlet pipe caused by the artificial wetland being used for a long time.

For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:

An annular radial constructed wetland, comprising a grid well, a constructed wetland, a water retaining wall and a water outlet pipe, the constructed wetland is provided with a filter packing layer inside, plants are planted on the top of the filter packing layer, and the permeable wall is provided with There are several water-permeable holes, which are characterized in that: the grid well is the center, followed by a permeable wall, a constructed wetland, and a water-retaining wall, the bottom of the constructed wetland is connected with evenly distributed outlet pipes, and the grid well A water inlet pipe is arranged at the center of the bottom.

A grill frame is also arranged inside the grill well.

The top of the grid well is provided with a well cover.

A walkway is also arranged between the permeable wall and the retaining wall.

The grid well, the permeable wall and the retaining wall are all circular in shape.

The constructed wetland is fan-shaped.

The utility model has the advantages that: the grid well is arranged in the center, which can save the occupied area, and the grid frame is arranged in the grid well to intercept the difficult-to-degrade substances in the sewage, so that the debris does not enter the artificial wetland, and the grid There is a well cover on the top of the grid well, which can prevent foreign matter from falling into it. There are many permeable holes on the permeable wall, and the sewage can quickly enter the artificial wetland for filtration. It is possible for the staff to enter the grid well to check its condition.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in the figure, an annular radial constructed wetland includes a grid well 3, a constructed wetland 4, a water retaining wall 10 and an outlet pipe 9, and the constructed wetland 4 is provided with a filter packing layer 5 inside, and the filter packing layer 5 Plants 1 are planted on the top, and several permeable holes 12 are arranged on the permeable wall 11, the grid well 3 is the center, and the permeable wall 11, the artificial wetland 4, the retaining wall 10, the artificial wetland The bottom of 4 is connected with uniformly distributed outlet pipes 9, the center of the bottom of the grill well 4 is provided with a water inlet pipe 6, the interior of the grill well 3 is also provided with a grill frame 7, and the top of the grill well 3 is provided with The manhole cover 2, the permeable wall 11 and the retaining wall 10 are also provided with a walkway 8, the grid well 3, the permeable wall 11 and the retaining wall 10 are all circular in shape, and the constructed wetland 4 is fan-shaped .

The working method of the utility model is: sewage enters the grid well 3 through the water inlet pipe 6, the grid frame 7 intercepts the difficult-to-degrade substances in the sewage, and the sewage enters the filter packing layer of the artificial wetland 4 through the permeable hole 12 of the permeable wall 11 5. Carry out filtration treatment. After the sewage filtration treatment is completed, since the bottom of the artificial wetland 4 is uniformly equipped with outlet pipes 9, the sewage can be quickly discharged through the nearest outlet pipe 9. Since there are multiple permeable holes on the permeable wall 11, if a Hole blockage does not affect the normal operation of the entire constructed wetland. There is a well cover on the top of the grid well 4, which can effectively prevent the odor of sewage from dispersing to the outside, and can also prevent foreign objects from falling into the inside. The aisle 8 is set to facilitate the staff Enter the grid well to see its condition.
