Description

Technical Field

[0001] The utility model relates to the technical field of estuarine wetland simulation test devices, in particular to an estuarine wetland simulation test device. Background Art

[0002] Estuarine wetlands refer to wetland areas formed when rivers flow into the ocean or lakes. Due to the particularity of their geographical location, estuarine wetlands play an important role in the natural environment. Estuarine wetlands can absorb and store a large amount of water, slow down the peak flow of floods, and play a role in regulating floods. At the same time, the roots of wetland plants can fix the soil and reduce the erosion of riverbanks and coasts. Therefore, protecting estuarine wetlands helps reduce the occurrence of floods and coastal erosion. Estuarine wetlands are important carbon sinks and climate regulators. Wetland plants absorb carbon dioxide through photosynthesis and fix it in the soil. The soil of estuarine wetlands is rich in organic matter and can store a large amount of carbon for a long time. At the same time, the transpiration of wetland plants can also reduce the temperature and regulate the climate.

[0003] According to the different elevations, estuarine wetlands are divided into high tide beaches, mid-tidal beaches and light beaches. Under the action of tides, substances are exchanged with the ocean every day. This device simulates the wetland ecosystem, sets up experimental and control groups, simulates the daily tides of seawater through water pumps, and sets pollutants of different concentrations to simulate the impact on the carbon sink capacity of estuarine wetlands in the event of severe marine pollution in the future. Utility Model Content

[0004] The utility model aims to provide an estuarine wetland simulation test device, which can simulate the impact on the carbon sequestration capacity of estuarine wetlands under the condition of severe marine pollution in the future by simulating the estuarine wetland ecosystem and setting up an experimental group and a control group.

The two drainage pumps pump the seawater in the laboratory and the control room into the two liquid storage tanks through the second connecting pipe to simulate the low tide phenomenon.

[0007] According to the estuarine wetland simulation test device, air blowers are respectively installed in the middle of the left and right sides of the simulation box, and the air blowers are respectively connected to the laboratory and the control room, and the flange of the air blower at one end away from the simulation box is connected to a one-way air valve, and the upper end of the top cover is equidistantly fixedly connected to a plurality of exhaust fans, and the upper end of the top cover is symmetrically fixedly connected to two activated carbon filter boxes, and the activated carbon filter boxes are respectively connected to the laboratory and the control room through the exhaust fans. The air blower and the exhaust fan cooperate to circulate the air in the laboratory and the control room with the outside world, adjust the temperature in the device, and ensure that the plants in the device grow normally before the test is opened. The activated carbon filter box filters the air in the device discharged by the exhaust fan to prevent the water vapor formed by the evaporation of seawater in the device from carrying pollutants into the outside air.
