Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a composite artificial wetland structure for rural sewage treatment. Background Technique

[0002] The rural population in China is scattered, and the cost of building sewage pipes connecting each household is relatively high. Therefore, it is difficult to centrally treat rural sewage. However, if the decentralized rural sewage is directly discharged into rivers without treatment, it will pollute the surface water quality. Therefore, it is necessary to treat the sewage through an artificial wetland.

[0003] An artificial wetland is a wetland built and controlled by humans. It uses the triple synergistic effects of physics, chemistry, and biology in the natural ecological system to purify sewage, effectively reducing the content of pollutants such as nitrogen and phosphorus in the sewage. However, the structures of some existing artificial wetlands for rural sewage treatment are significantly affected by seasons. Factors such as low winter temperatures, withered and dead plants, and reduced activity of nitrogen-releasing microorganisms will weaken the ability of the artificial wetland to remove nitrogen and phosphorus pollutants, thereby reducing the purification ability of wetland plants and affecting the normal treatment of sewage. Therefore, in view of the above problems, a composite artificial wetland structure for rural sewage treatment is proposed. Content of the Utility Model

[0027] The sedimentation tank 1, the first treatment tank 2, and the second treatment tank 3 are all rectangular tanks. There is a water inlet hole on the front side of the sedimentation tank 1, and there are two overflow outlets on the rear side of the sedimentation tank 1. There are two water inlets on the front side of the first treatment tank 2, and there is a drain hole on the rear side of the second treatment tank 3. There are two overflow pipes 9, which can input the overflowing sewage from the sedimentation tank 1 into the first treatment tank 2. There is a rectangular fixing groove on the rear side of the first treatment tank 2, and there is a rectangular fixing groove on the front side of the second treatment tank 3. The first filter plate 10 is a rectangular metal sieve plate, and the second filter plate 11 is a rectangular activated carbon plate, which can transport the sewage from the first treatment tank 2 to the second treatment tank 3. The glass plate 4 is horizontally distributed, and the glass plate 4 has good light transmittance. There are multiple infrared heating tubes 5, which are evenly distributed in the front-rear direction. The bottom of the infrared heating tube 5 is in contact with the glass plate 4. Through the glass plate 4, it can prevent sewage from seeping into the infrared heating tube 5. There are circular ventilation holes on the left rear side and the right front side of the heat preservation shell 6, and there are circular ventilation holes on the left rear side and the right front side of the heat preservation greenhouse 13. The first air exchange pipe 15 and the second air exchange pipe 16 are both circular bent pipes, which can circulate the air in the sedimentation tank 1, the first treatment tank 2, and the second treatment tank 3. The controller 7 is electrically connected to the infrared heating tube 5, the solar panel assembly 8, and the air pump 14 respectively. The solar panel assembly 8 is composed of a solar panel, a support shaft, and a storage battery. The bottom of the solar panel of the solar panel assembly 8 is fixedly connected to the support shaft, and the side of the support shaft of the solar panel assembly 8 is fixedly connected to the storage battery.

Through the positioning frame 12, the heat preservation greenhouse 13 can be hermetically connected to the first treatment tank 2 and the second treatment tank 3.

[0028] Workflow: The controller 7 of this device is electrically connected to the infrared heating tube 5, the solar panel assembly 8, and the air pump 14 respectively, and the infrared heating tube 5, the solar panel assembly 8, and the air pump 14 can be controlled respectively through the controller 7. This is the prior art. Before use, install the device at a suitable location. The device is installed in an open area outdoors in the countryside. The sedimentation tank 1, the first treatment tank 2, and the second treatment tank 3 are all set underground, so that the top of the second treatment tank 3 and the positioning frame 12 are at the same height as the ground, and part of the sedimentation tank 1 and the first treatment tank 2 are located above the ground. And fix the end of the rural sewage drain pipe at a position slightly below the front side of the sedimentation tank 1, then the installation can be completed. When the device is in normal use, it collects sewage through the water inlet hole on the front side of the sedimentation tank 1. The sewage accumulates and precipitates in the sedimentation tank 1. The particulate matter in the sewage can be physically precipitated. When the sewage level is higher than the overflow pipe 9, part of the precipitated sewage will flow backward into the first treatment tank 2 through the overflow pipe 9. There are materials beneficial to the growth of microorganisms such as mud and plant decay products in the first treatment tank 2, which can enable the rapid reproduction of microorganisms. The microorganisms can biologically purify the sewage and effectively reduce the content of pollutants such as nitrogen and phosphorus in the sewage. After the sewage is filtered by the first filter plate 10 and the second filter plate 11, it enters the second treatment tank 3. There are soil and aquatic plants in the second treatment tank 3, which can further purify the sewage. The purified sewage can be discharged from the drain hole on the rear side of the second treatment tank 3. Since the sedimentation tank 1, the first treatment tank 2, and the second treatment tank 3 of this device are relatively large in volume, they can store more sewage. The sewage generated by the user is less compared to the volume of the sedimentation tank 1, the first treatment tank 2, and the second treatment tank 3. Therefore, there is no need to set a switching valve. The device discharges the treated sewage, and the treated sewage can enter the natural world. When the temperature drops, the solar panel assembly 8 can supply power to the infrared heating tube 5, the controller 7, and the air pump 14. The infrared heating tube 5 and the air pump 14 are started through the controller 7. The top of the sedimentation tank 1 is sealed by the glass plate 4 to prevent sewage from seeping into the infrared heating tube 5. The sewage in the sedimentation tank 1 is heated by the infrared heating tube 5. The heat dissipated by the infrared heating tube 5 makes the air on the upper side of the glass plate 4 heat up and become hot air. At the same time, the air inside the sedimentation tank 1 sealed by the heat preservation shell 6 is pumped out by the air pump 14 and transported to the inside of the first treatment tank 2 and the second treatment tank 3 sealed by the heat preservation greenhouse 13 through the first air exchange pipe 15. Together with the second air exchange pipe 16, an air circulation can be formed between the sedimentation tank 1 and the first treatment tank 2 and the second treatment tank 3, so that the hot air inside the sedimentation tank 1 is evenly distributed into the first treatment tank 2 and the second treatment tank 3, heating the whole device, and heat preservation is carried out through the heat preservation shell 6 and the heat preservation greenhouse 13;The device can heat and keep warm the sewage and air inside the device when the ambient temperature is relatively low, prevent the sewage from freezing, prevent the plants from withering, and ensure the activity of microorganisms, so as to ensure the wetland's ability to remove nitrogen and phosphorus pollutants. Furthermore, it ensures that the purification ability of wetland plants is not affected by the environmental stability and reduced, enabling the sewage to be treated normally.
