Description

Technical Field

[0001] This utility model relates to the field of vegetation reconstruction technology, specifically to a water treatment and recycling system for vegetation reconstruction. Background Technology

[0002] During the vegetation restoration process, sufficient water is needed to irrigate the vegetation. However, the irrigation process generates wastewater containing a large amount of sediment. In order to save water resources, the wastewater is usually treated and recycled.

[0003] For example, CN 214936660 U discloses a water treatment recycling system for vegetation restoration, which includes a filter box, a guide hopper fixedly connected to the top edge of the filter box, and filter inclined plates symmetrically fixedly connected to the middle of the inner side of the filter box. Discharge slots are opened on both sides of the filter box corresponding to the bottom edges of the filter inclined plates. This system adds wastewater to the filter box through the guide hopper. By rotating a brush roller, it can intercept the wastewater flowing down the top of the filter inclined plates, and also transport the silt accumulated at the top and bottom of the filter inclined plates, allowing the silt inside the filter box to pass through the discharge slots into the discharge hopper and be discharged from the bottom of the discharge hopper. This system aims to effectively reduce the content of large particulate impurities in wastewater by intercepting silt inside the wastewater, thereby reducing the difficulty of wastewater treatment and improving the treatment effect. However, the following problems still exist: if the filter box is raised, the wastewater also needs to be sent to a higher position for filtration, resulting in high energy consumption. Utility Model Content

[0004] The purpose of this invention is to provide a water treatment and recycling system for vegetation restoration that is structurally sound, reliable in use, and facilitates water reuse with low energy consumption, thereby solving the above-mentioned problems.

[0005] The technical solution of this utility model is:

[0006] A water treatment and circulation system for vegetation restoration includes an infiltration chamber constructed below the vegetation restoration soil layer. The key technical features are: a water collection trough with its top higher than the vegetation restoration soil layer is located at the end of the infiltration chamber; a horizontal spiral conveyor is located at the bottom of the water collection trough; a primary filter layer and a secondary filter layer are sequentially arranged from bottom to top on the upper part of the water collection trough, with the pore size of the secondary filter layer being smaller than that of the primary filter layer; a reprocessing tank adjacent to the water collection trough is located in the vegetation restoration soil layer; an overflow pipe communicating with the reprocessing tank is located on the side wall of the water collection trough; a stirring mechanism is located in the reprocessing tank; a drainage pipe is also located in the reprocessing tank; a lift pump communicating with the drainage pipe is fixed to the upper part of the side wall of the reprocessing tank near the vegetation restoration soil layer; a Y-direction pipe communicating with the outlet of the lift pump and multiple X-direction pipes communicating with the Y-direction pipe are arranged above the vegetation restoration soil layer; multiple water passage holes are spaced apart on the X-direction pipes.

[0007] In the aforementioned water treatment circulation system for vegetation restoration, the overflow pipe is equipped with a discharge pipe at the top, a chemical hopper is fixed at the top of the discharge pipe, and a flow control valve is provided at the lower end of the chemical hopper.

[0008] The aforementioned water treatment circulation system for vegetation restoration has multiple first support blocks corresponding to the Y-direction pipeline and multiple second support blocks corresponding to the X-direction pipeline on the upper surface of the vegetation restoration soil layer.

[0009] In the aforementioned water treatment and recycling system for vegetation restoration, the stirring mechanism is a longitudinal stirring paddle, and a drive motor connected to the longitudinal stirring paddle is fixed at the top of the reprocessing tank.

[0010] In the aforementioned water treatment and circulation system for vegetation restoration, the drainage pipe is fixed to the side wall of the reprocessing tank, with its lower end extending to the middle of the side wall of the reprocessing tank.

[0011] The beneficial effects of this utility model are:

[0012] After seeping into the infiltration chamber beneath the vegetation-reconstructed soil layer, the water enters the collection tank. After undergoing double filtration, the overflow flows into the reprocessing tank. With the assistance of a stirring mechanism, it is treated with chemicals and finally reaches the various X-directional pipes via drainage pipes, a lift pump, and Y-directional pipes. From there, it seeps into the vegetation-reconstructed soil layer through water passages on the X-directional pipes, achieving water recycling. During this process, silt and sediment in the wastewater settle at the bottom of the collection tank and can be periodically discharged to the outside of the tank by a horizontal rotary conveyor. The entire process eliminates the need to raise water containing large amounts of silt, facilitating water reuse and reducing energy consumption. Attached Figure Description

[0015] The present invention will be described in detail with reference to the accompanying drawings.

[0016] like Figure 1As shown, the water treatment and circulation system for vegetation restoration includes an infiltration cavity 20 constructed below the vegetation restoration soil layer 1, and a water collection trough 14 with its top higher than the vegetation restoration soil layer 1 is provided at the end of the infiltration cavity 20.

[0017] The bottom of the water collection tank 14 is equipped with a horizontal spiral conveyor 17. The upper part of the water collection tank 14 is provided with a primary filter layer 16 and a secondary filter layer 15 from bottom to top, and the pore size of the secondary filter layer 15 is smaller than that of the primary filter layer 16.

[0018] The vegetation reconstruction soil layer 1 is provided with a reprocessing tank 18 adjacent to the water collection tank 14. The side wall of the water collection tank 14 is provided with an overflow pipe 13 that communicates with the reprocessing tank 18. In this embodiment, the top of the overflow pipe 13 is provided with a discharge pipe 12, and the top of the discharge pipe 12 is fixed with a chemical hopper 10. The lower end of the chemical hopper 10 is provided with a flow control valve 11.

[0019] The reprocessing tank 18 is equipped with a stirring mechanism 19. In this embodiment, the stirring mechanism 19 is a longitudinal stirring paddle, and a drive motor 9 connected to the longitudinal stirring paddle is fixed to the top of the reprocessing tank 18.

[0020] The reprocessing tank 18 is further provided with a drainage pipe 8, which is fixed to the side wall of the reprocessing tank 18, with its lower end extending to the middle of the side wall of the reprocessing tank 18. A lift pump 7, connected to the drainage pipe 8, is fixed to the upper part of the side wall of the reprocessing tank 18 near the vegetation reconstruction soil layer 1. Above the vegetation reconstruction soil layer 1, a Y-direction pipe 6 connected to the outlet of the lift pump 7 and multiple X-direction pipes 3 connected to the Y-direction pipe 6 are arranged, with multiple water passage holes 4 spaced apart on the X-direction pipes 3. In this embodiment, the upper surface of the vegetation reconstruction soil layer 1 is provided with multiple first support blocks 5 corresponding to the Y-direction pipes 6 and multiple second support blocks 2 corresponding to the X-direction pipes 3.

[0021] Working principle:

[0022] During operation, a portion of the irrigation water seeps into the infiltration cavity 20 below the vegetation reconstruction soil layer 1, and then enters the collection trough 14. As the water rises, it undergoes double filtration through the primary filter layer 16 and the secondary filter layer 15, with large particles of silt deposited at the bottom of the collection trough 14.

[0023] The rising water eventually enters the reprocessing tank 18 through the overflow pipe 13. During this process, the chemical hopper 10 uses the flow control valve 11 to evenly release the chemical and disperse it in the overflow water. Then, the water is evenly stirred in the reprocessing tank 18 by the stirring mechanism 19 to ensure the chemical treatment effect.

[0024] Finally, the booster pump 7 is started, so that the water can reach each X-direction pipe 3 through the diversion pipe 8, the booster pump 7, and the Y-direction pipe 6, and then seep back into the vegetation reconstruction soil layer 1 through the water passage hole 4 on the X-direction pipe 3, so as to realize the water treatment and recycling.

[0025] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
