Description

Technical Field

[0001] The present invention relates to the technical field of artificial wetlands, and in particular to an integrated system for monitoring and controlling greenhouse gases in wetlands. Background Art

[0002] In the past 20 years, with the rapid advancement of global industrialization and urbanization, artificial wetlands, as an effective means of sewage treatment, have been continuously expanded in construction and operation, playing a positive role in improving water environment quality. However, this process is also accompanied by the problem of greenhouse gas emissions, posing new challenges to climate change and ecological environmental protection. According to relevant studies, artificial wetlands will produce a certain amount of greenhouse gases such as CO2, CH4 and N2O while treating sewage. The emission of these gases has a significant impact on the global warming potential, and effective measures are urgently needed to control and reduce emissions.

[0003] Regarding greenhouse gas emissions from artificial wetlands, factors such as influent water quality, wetland structure, and plant types all have important impacts on the generation and emission of gases. For example, different plant types have different abilities to absorb and release greenhouse gases, and the design of wetland structures also affects the diffusion and transmission efficiency of gases. Therefore, optimizing the design and operation of artificial wetlands is of great significance for reducing greenhouse gas emissions.

This scheme uses intermittent water inlet and tidal operation mode, and the upper filling area of ​​the vertical flow artificial wetland is in a pulsed water-filled aerobic state. However, its disadvantage is that it does not consider the carbon sink of plants in the wetland and the impact of carbon on greenhouse gas changes. It is difficult to regulate greenhouse gases in real time and accurately only by water flow control.

[0005] In summary, the problem to be solved by the present invention is how to regulate greenhouse gases in real time and accurately. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reducing carbon emissions caused by greenhouse gas emissions such as CO2 and CH4 has become a focus of attention and an important criterion for measuring water pollution treatment technologies. Artificial wetlands have both water purification and landscape effects, and have the advantages of low construction and operating costs, convenient operation and management, good purification effects, and strong impact load resistance.

[0034] According to existing technologies, artificial wetlands are artificial ecosystems that simulate natural wetlands. They are a type of swamp-like ground that is artificially constructed and controlled. They are composed of one or more media such as stone, sand, soil, and coal slag in a certain proportion, and are a sewage treatment ecosystem in which plants are selectively implanted.

[0035] Regarding greenhouse gas emissions from existing artificial wetlands, factors such as influent water quality, wetland structure, and plant type all have a significant impact on gas generation and emissions. For example, different plant types have different abilities to absorb and release greenhouse gases, and the design of the wetland structure also affects the diffusion and transmission efficiency of gases.

[0036] In order to achieve real-time and accurate control and regulation of greenhouse gases, this embodiment proposes an integrated greenhouse gas monitoring and regulation system for an artificial wetland 1, comprising: a gas monitoring system 3, wherein the gas monitoring system 3 comprises a plurality of monitoring units connected to each other and evenly distributed in the wetland, any of the monitoring units comprising a gas collecting device, a sensing module 3-4-6 connected to the gas collecting device, and the sensing module 3-4-6 is connected to a microprocessor 3-4-2; a regulation system 4, wherein the regulation system 4 comprises a control unit 4-3, a control valve electrically connected to the control unit 4-3, an outlet pipe 4-7 and a return pipe 4-8, wherein the outlet pipe 4-7 is provided with a second control valve 4-6, and the return pipe 4-8 is provided with a first control valve 4-5; a sewage pipe 5, wherein the outlet pipe 4-7 is connected to the sewage pipe 5.

[0037] In this embodiment, after the sewage pipe 5 is connected to the artificial wetland, the sewage enters the artificial wetland after passing through the sewage pipe 5. Since the gas monitoring system 3 is configured on the artificial wetland, each monitoring unit collects gas through the gas collection device, and monitors the greenhouse gas flux through the sensing module 3-4-6, and calculates through the microprocessor 3-4-2. The microprocessor 3-4-2 is connected to the control unit 4-3, and the microprocessor 3-4-2 sends the calculation result to the control unit 4-3. Since the control unit is connected to the control valve through the cable 4-4, the control unit 4-3 is based on The information controls the opening and closing of the control valve. When the control valve located in the outlet pipe is opened and the control valve located in the return pipe is closed, the water flow can be discharged into the sewage pipe 5; when the control valve located in the return pipe is opened and the control valve located in the outlet pipe is closed, the water flow flows from the return pipe to the water flow discharged from the sewage pipe 5, thereby diluting the incoming water concentration and reducing the processing load to achieve the purpose of reducing greenhouse gas emissions. Therefore, this embodiment realizes real-time and precise control of greenhouse gas emissions through the integration of the gas monitoring system 3 with the control system 4 and the sewage pipeline.

[0038] Furthermore, the gas collection device at least includes a base and a gas collecting hood connected to the base, and the sensing module 3-4-6 is installed on the gas collecting hood.

[0039] It can be understood that the base is connected to the air collecting hood, and the base can support the air collecting hood. At the same time, the air collecting hood is placed on the wetland plants, that is, the base can contact the ground of the wetland and support the air collecting hood. The base surrounds several plants and maintains isolation from the outside. The air collecting hood surrounds the plants to form a relatively independent system.

[0040] Here, it should be noted that the gas collecting hood can be made of acrylic material, which has the characteristics of being light, transparent, and easy to process, and has little effect on the photosynthesis of wetland plants.

[0041] Preferably, the air collecting hood comprises a separable first air collecting hood 3-4-1 and a second air collecting hood 3-3, wherein the first air collecting hood is detachably linked to the second air collecting hood, and the second air collecting hood is detachably connected to the base.

[0043] Preferably, the second air collecting hood is formed by connecting two or more collective barrels in sequence.

[0044] In this embodiment, the second gas collecting hood is designed to be composed of more than two collective barrels connected in sequence, so that the number of middle gas collecting barrels can be freely increased or decreased according to the plant height or different growth stages, and the adaptability is strong.

[0045] Furthermore, a gas mixing device is provided inside the gas collecting hood, and the gas mixing device mixes the gas inside the gas collecting hood by disturbing the airflow; the gas mixing device is electrically connected to the microprocessor 3-4-2.

[0046] It is understandable that due to the large volume of the gas collecting hood, under normal circumstances, the gas distribution in the gas collecting hood is not uniform. In order to improve the accuracy of collection and reduce the number of sensing units, the gas mixing device is used to disturb the airflow so that the airflow in the gas collecting hood is relatively evenly distributed, thereby improving the accuracy of data collection by the sensing unit.

[0047] Preferably, the gas mixing device comprises at least a fan 3-4-5.

[0048] In order to reduce costs, the gas mixing device may include a fan, such as Figure 2 As shown, the fan is hung on the housing of the microprocessor 3-4-2, and the housing provides support for the fan.

[0049] Furthermore, the base includes a fixing tooth 3-1-1, a first sealing unit 3-1-2 and a second sealing unit 3-2, the fixing tooth is connected to the first sealing unit, one side of the second sealing unit is connected to the first sealing unit, and the other side of the second sealing unit is detachably connected to the air collecting hood.

[0050] It can be understood that the fixed teeth are used to increase the contact area and reliability between the base and the artificial wetland. The first sealing unit and the second sealing unit preferably use sealing rings. The use of sealing rings can not only ensure the airtightness of the connection with the air collecting hood and the fixed teeth, but also realize a detachable connection with low cost.

[0051] Preferably, the second sealing unit is screwed together with the air collecting hood.

[0052] By selecting the second sealing unit as a sealing ring with threads, a threaded structure is also provided on the gas collecting hood, and the second sealing unit and the gas collecting hood can be tightly matched by screwing.

[0053] Furthermore, the gas collection device also includes a first energy storage unit 3-4-3, the first energy storage unit is connected to a first solar cell panel 3-4-4, the first solar cell panel is connected to the gas collecting hood, and a space is formed between the first solar cell panel and the gas collecting hood, and the energy storage unit is fixed inside the space.

[0054] Taking into account that there is sufficient solar energy in the artificial wetland system, in this embodiment, a first solar panel and a first energy storage unit are provided. The first solar panel can collect solar energy and convert it into electrical energy, wherein the solar panel is also called a photovoltaic module. By storing the electrical energy in the first energy storage unit, electrical energy can be provided to the sensing module 3-4-6, the microprocessor 3-4-2, and the gas mixing device.

[0055] Furthermore, the control system 4 includes a second energy storage unit 4-2, the second energy storage unit is connected to the control unit 4-3, and the control unit 4-3 is connected to the second solar cell panel 4-1.

[0056] Similarly, the control system 4 is re-installed with a second solar panel and a second energy storage unit. The second solar panel can collect solar energy and convert it into electrical energy. By storing the electrical energy in the second energy storage unit, electrical energy can be provided to the control unit 4-3.

[0057] It can be understood that the first solar cell panel and the second solar cell panel can also be shared, and the first energy storage unit and the second energy storage unit can also be shared.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
