Abstract
The utility model discloses a kind of vertical subsurface flow wetland structure, comprise the exterior wall that is distributed in surrounding and by exterior wall encirclement, the coarse sands layer distributed successively, little gravel bed, boulderet rock layers, large gravel bed, bottom described large gravel bed, be equipped with one deck LDPE lining from top to bottom; Described vertical subsurface flow wetland structure also comprises many water service pipes, and described water service pipe crosses coarse sands layer, little gravel bed, boulderet rock layers and large gravel bed, and described large gravel bed is provided with a water shoot, and described many water service pipes are connected with described water shoot; Described coarse sands layer, little gravel bed, boulderet rock layers and large gravel bed are all arranged according to the gradient of 1%; The thickness of described coarse sands layer, little gravel bed, boulderet rock layers and large gravel bed meets 1:3:2:3.Vertical subsurface flow wetland structure of the present utility model had both ensured the good living environment of plant, in turn ensure that the smooth and easy circulation of the undercurrent of vertical direction.
Description
Technical field
The utility model relates to building field, gardens, particularly about vertical subsurface flow wetland structure.
Background technology
Artificial swamp is the ground similar with swampland by artificial construction and controlling run, sewage, mud there is the dosing of control on the artificial wetland built, sewage and mud, in the process flowed in a certain direction, mainly utilize soil, artificial dielectric, plant, the physics of microorganism, chemistry, biological triple synergy.In the construction of artificial swamp, the construction of aquatic vegetation is an important difficult point, the survival rate improving waterplant must be made great efforts, but because different plant is to the requirement difference of weather soil and water resources, cause aquatic vegetation easily to occur the problem of disruption of ecological balance.
At present, China's quality of water environment problem emerges in an endless stream, and wherein insoluble is pollution of area source from rural area, small towns, and Artificial Wetland Techniques advantage that is simple because of its technique, low cost is highly suitable for the sewage processing rural area, vast small towns.Up to now, only Jiangsu Province's Changzhou just builds more or less a hundred artificial swamp for the treatment of dispersant type domestic wastewater, along with the development of Chinese national economy, will drop into more fund for administering water surrounding, Artificial Wetland Techniques also will obtain wider application.Rational in infrastructure, both ensure the good living environment of plant, in turn ensure that the wide market of the vertical subsurface flow wetland structure of the smooth and easy circulation of the undercurrent of vertical direction.
Utility model content
In view of this, the utility model is for solving the problems of the technologies described above, there is provided a kind of vertical subsurface flow wetland structure of more reasonable structure, vertical subsurface flow wetland structure of the present utility model had both ensured the good living environment of plant, in turn ensure that the smooth and easy circulation of the undercurrent of vertical direction.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vertical subsurface flow wetland structure, comprises the exterior wall that is distributed in surrounding and by exterior wall encirclement, the coarse sands layer distributed successively, little gravel bed, boulderet rock layers, large gravel bed, is equipped with one deck LDPE lining bottom described large gravel bed from top to bottom; Described vertical subsurface flow wetland structure also comprises many water service pipes, and described water service pipe crosses coarse sands layer, little gravel bed, boulderet rock layers and large gravel bed, and described large gravel bed is provided with a water shoot, and described many water service pipes are connected with described water shoot; Described coarse sands layer, little gravel bed, boulderet rock layers and large gravel bed are all arranged according to the gradient of 1%; The thickness of described coarse sands layer, little gravel bed, boulderet rock layers and large gravel bed meets 1:3:2:3.
Described water service pipe epimere and coarse sands layer contact part are provided with for the protection of water service pipe and are wrapped in the hard tube outside water service pipe, and described hard tube is higher than transverse plane on coarse sands layer.
Described coarse sands layer planting plants, the root of described plant is distributed in coarse sands layer and little gravel bed.
The described water shoot place of being close to the exit is provided with ratchel.
The utility model compared to the beneficial effect of prior art is:
The artificial swamp structure that vertical subsurface flow wetland structure of the present utility model utilizes four layers to tilt, had both ensured the good living environment of plant, in turn ensure that the smooth and easy circulation of the undercurrent of vertical direction.The depth size of wetland will consider that root system of plant cures by oxygen therapy the degree of depth that can arrive, and to ensure aerobic condition necessary in wetland unit, the degree of depth too conference causes root system to cure by oxygen therapy bottom, also easily causes slough simultaneously.By coarse sands layer, little gravel bed, boulderet rock layers and large gravel bed that the thickness proportion of 1:3:2:3, the gradient of 1% are arranged, both ensure that the smooth and easy circulation of the undercurrent of vertical direction, in turn ensure that the necessary aerobic condition in wetland unit, for plant provides good living environment.Because the root of plant mainly concentrates on coarse sands layer, and there is the coring of partial span in little gravel bed; Consider the shape of coring mostly to be thin and long strip, the normal extension for guarantee coring is not subject to larger obstruction and affects growth, and the thickness of little gravel bed is three times of coarse sands layer, and the extension for coring provides sufficient space.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is the structure iron of vertical subsurface flow wetland structure of the present utility model.
Embodiment
The utility model to be described in further detail below in conjunction with accompanying drawing and embodiment for the ease of it will be appreciated by those skilled in the art that.
Please refer to Fig. 1, the utility model embodiment comprises:
A kind of vertical subsurface flow wetland structure, comprises the exterior wall 1 being distributed in surrounding and the coarse sands layer 2, little gravel bed 3, boulderet rock layers 4, the large gravel bed 5 that are surrounded by exterior wall 1, distribute successively from top to bottom, is equipped with one deck LDPE lining 51 bottom large gravel bed 5; Vertical subsurface flow wetland structure also comprises 10 water service pipes 6, and water service pipe 6 crosses coarse sands layer 2, little gravel bed 3, boulderet rock layers 4 and large gravel bed 5, and large gravel bed 5 is provided with a water shoot 7, and many water service pipes 6 are connected with water shoot 7; Coarse sands layer 2, little gravel bed 3, boulderet rock layers 4 and large gravel bed 5 are all arranged according to the gradient of 1%; The thickness of coarse sands layer 2, little gravel bed 3, boulderet rock layers 4 and large gravel bed 5 meets 1:3:2:3.
Water service pipe 6 epimere and coarse sands layer 2 contact part are provided with for the protection of water service pipe and are wrapped in the hard tube 61 outside water service pipe, and hard tube 61 is higher than transverse plane on coarse sands layer 2.
