Problems solved by technology

The publicity and protection of wetlands has a long way to go. The publicity of wetlands in the current science popularization activities is mainly limited to text introduction, pictures, video display and other means.
At present, the models used for relevant wetland science popularization are all simulation models, which can only imitate and display the environmental structure of wetlands and other apparent content, and cannot actually display the operation mode and effect of wetlands.

Embodiment 1

[0036] Such as figure 1As shown, a constructed wetland model in a preferred embodiment of the present invention includes a water reservoir, a water inlet pipe 1, a color developer and at least one simulated wetland unit, the water reservoir is used to hold sewage, and the color developer is used to add sewage to Perform color reaction with pollutants in sewage. The simulated wetland unit includes a container 2, a substrate 3 and wetland plants 4. The container 2 is in the shape of a box with an open top. The side of the container 2 is provided with a water outlet, and the water inlet pipe 1 is connected to a water pump 5. , the first end of the water inlet pipe 1 leads into the water reservoir, the second end of the water inlet pipe 1 leads into the container 2, the substrate 3 is laid in the container 2, the wetland plants 4 are planted on the substrate 3, the water reservoir and the outlet The water port is connected to collect the sewage flowing through the container 2 . I...

Embodiment 2

[0044] Such as figure 2 and image 3 As shown, the difference between this embodiment and Embodiment 1 is that the model of this embodiment includes two or more simulated wetland units, and the model of this embodiment uses three simulated wetland units. Furthermore, each simulated wetland unit is arranged in steps in the vertical direction, and a raising device is provided under the simulated wetland unit with a higher level. The raising device in this embodiment is a pad 10, and the pad 10 adopts Ladder, the ladder is formed by stacking backing boards with a thickness of 2cm. Multiple backing boards can be combined to form different height differences and adjust the flow rate of sewage. The water inlet pipe 1 leads to the simulated wetland unit with the highest level, and the water outlet of the simulated wetland unit with a higher level communicates with the container 2 of the adjacent simulated wetland unit with a lower level, and the lowest level The water outlet of th...

Embodiment 3

[0052] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that the water outlet in this embodiment includes a second water outlet 202 and a third water outlet 203, the second water outlet 202 is located above the third water outlet 203, and the third water outlet 203 is located below the top surface of the matrix 3; the second water outlet 202 communicates with the water inlet pipe 1, and the third water outlet 203 communicates with the water storage, so that the sewage enters the container 2 through the second water outlet 202 and penetrates into the matrix 3 Then flow out from the third water outlet 203; or the third water outlet 203 is communicated with the water inlet pipe 1, and the second water outlet 202 is communicated with the water storage device, so that the sewage enters the matrix 3 in the container 2 through the third water outlet 203, and seeps After exiting the substrate 3, it flows out from the second water outlet 202. The ...

Abstract

The invention relates to the technical field of science and education tools, and discloses an artificial wetland model. The artificial wetland model comprises a water storage device, a water inlet pipe, a color developing agent and at least one simulated wetland unit, wherein the water storage device used for containing sewage; the color developing agent is used for being added into the sewage fora color developing reaction with pollutants in the sewage; the simulated wetland unit comprises a container, a matrix and wetland plants; the container is in the shape of a box with an opening in thetop, and a water outlet is formed in the side of the container; the water inlet pipe is connected with a water pump, two ends of the water inlet pipe are respectively introduced into the water storage device and the container; the matrix is laid in the container; the wetland plants are planted on the matrix; and the water storage device communicates with the water outlet to collect sewage flowingthrough the container. The sewage can circularly flow in the model, so the model disclosed by the invention can simulate the operation of a real constructed wetland, the purification function of thewetland is intuitively expressed through the color difference of the water storage device, the interestingness and participation of science popularization activities are increased, and the operationalability of a taught person is improved. The invention further provides an operation method of the constructed wetland model.

Description

technical field [0001] The invention relates to the technical field of scientific and educational tools, in particular to an artificial wetland model and an operating method. Background technique [0002] Wetlands are precious natural resources and important ecosystems with irreplaceable comprehensive functions. Constructed wetlands constructed to simulate wetland structures are also widely used in sewage treatment and environmental improvement. The publicity and protection of wetlands has a long way to go. The publicity of wetlands in the current science popularization activities is mainly limited to text introduction, pictures, video display and other means. At present, the models used for relevant wetland science popularization are all simulation models, which can only imitate and display the environmental structure of wetlands and other apparent content, and cannot actually display the operation mode and effect of wetlands. Contents of the invention [0003] The purp...
