Description

Technical Field

[0001] The utility model relates to the technical field of water purification systems, in particular to a high-altitude tail water deep purification treatment system adopting a surface flow wetland process. Background Art

[0002] High-altitude areas often experience cold weather, large temperature swings between day and night, and relatively low oxygen levels. These unique climatic conditions pose significant challenges to the performance of traditional water purification systems. First, low temperatures slow biochemical reactions and reduce microbial activity, thereby impacting the decomposition and removal of organic matter during the purification process. Second, low oxygen levels restrict the respiration of aquatic organisms and microorganisms, further weakening the biological treatment capacity of the purification system.

[0003] Furthermore, the ecological environment in high-altitude areas is often more fragile and highly sensitive to external disturbances. Traditional water purification systems, such as those using chemicals or high-intensity mechanical treatment, may introduce new pollutants or cause irreversible damage to local ecosystems. For example, chemical residues can contaminate water sources, affecting the survival of aquatic life, and even be transferred to higher trophic levels through the food chain, threatening the entire ecosystem. Utility Model Content

[0004] The purpose of the present utility model is to provide a deep purification treatment system for tail water in high altitude areas using a surface flow wetland process, so as to solve the problem that the traditional water purification treatment system proposed in the above background technology, such as the use of chemical agents or high-intensity mechanical treatment methods, may introduce new pollutants or cause irreversible damage to the local ecosystem.

[0005] To achieve the above-mentioned purpose, the utility model provides a deep purification treatment system for tail water in high-altitude areas using a surface flow wetland process, comprising a purification ditch, a soil layer is arranged inside the purification ditch, a matrix layer is arranged at the bottom of the soil layer, a plurality of partitions are installed inside the purification ditch, and the partitions are arranged at equal intervals. An inlet pipe is installed on one side of the purification ditch, and an outlet pipe is installed on the other side of the purification ditch.

[0006] Preferably, a mesh plate is provided between the soil layer and the substrate layer.

[0007] Preferably, a water pipe is installed transversely on the partition at the top of the soil layer.

[0008] Preferably, a slot is provided on the top of the partition, a lifting plate is inserted into the slot, and the lifting plate is locked and fixed by a locking bolt.

[0009] Preferably, a water inlet valve is installed on the water inlet pipe, and a water outlet valve is installed on the water outlet pipe.

[0010] Preferably, filter screens are installed at both ends of the water pipe.

[0011] Preferably, the partition divides the interior of the purification ditch into several planting areas.

[0012] Preferably, both sides of the purification groove are sloped surfaces.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This high-altitude tailwater deep purification system, utilizing a surface-flow wetland process, effectively adapts to the unique climatic conditions of high altitudes through optimized design. The system's internal soil layer, substrate layer, and mesh panels not only provide ample space for microorganisms to attach and grow, but also enhance the system's purification capacity, ensuring efficient removal of organic matter and other pollutants from the tailwater.

[0015] At the same time, evenly spaced partitions divide the interior of the purification trench into multiple planting areas, facilitating plant cultivation and management while enhancing the system's ecological diversity and purification efficiency. Furthermore, valves installed on the inlet and outlet pipes, as well as filters at both ends of the pipes, further ensure the system's stable operation and the quality of tailwater purification.

[0016] In summary, the treatment system of the present invention not only significantly improves the purification efficiency of tail water in high-altitude areas, but also effectively protects the local ecological environment. It has broad application prospects and important practical significance. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a high altitude area tail water deep purification treatment system using surface flow wetland technology, such as Figure 1-Figure 3 As shown, it includes a purification trench 1, a soil layer 11 is provided inside the purification trench 1, a matrix layer 12 is provided at the bottom of the soil layer 11, a plurality of partitions 3 are installed inside the purification trench 1, and the partitions 3 are arranged at equal intervals. An inlet pipe 13 is installed on one side of the purification trench 1, and an outlet pipe 14 is installed on the other side of the purification trench 1. The matrix layer 12 is made of porous environmentally friendly ceramic filter balls or natural mineral materials. The porous environmentally friendly ceramic filter balls have excellent adsorption properties and certain mechanical strength and are suitable for artificial wetland systems. It can remove pollutants through adsorption and photocatalytic degradation, and prolong the pollutant adsorption saturation time of the matrix. Natural mineral materials such as zeolite, vermiculite, anthracite, steel slag, etc. have good adsorption properties and ion exchange capacity, and can effectively remove nutrients such as nitrogen and phosphorus and heavy metal ions in water.

[0024] In this embodiment, a mesh plate 2 is provided between the soil layer 11 and the matrix layer 12 to separate the soil layer 11 from the matrix layer 12 and facilitate water flow.

[0025] Specifically, a water pipe 31 is horizontally installed on the partition 3 at the top of the soil layer 11 to facilitate water flow when the water flow is large and to facilitate water guidance to each planting area.

[0026] Furthermore, a slot 33 is provided at the top of the partition 3, and a lifting plate 32 is inserted into the slot 33. The lifting plate 32 is locked and fixed by a locking bolt 34, which facilitates the lifting operation of the partition 3. When the water flow is large, the lifting plate 32 is raised to ensure that the water flow is blocked.

[0027] Furthermore, a water inlet valve 131 is installed on the water inlet pipe 13, and a water outlet valve 141 is installed on the water outlet pipe 14, so as to facilitate the control of water inlet and water outlet.

[0028] Furthermore, filter screens 311 are installed at both ends of the water pipe 31 to block impurities and prevent the water pipe 31 from being blocked.

[0029] Furthermore, the partition 3 divides the interior of the purification ditch 1 into several planting areas, which is convenient for planting vegetation.

[0030] Furthermore, both sides of the purification ditch 1 are sloped surfaces, which facilitates water flow into the soil layer 11.

[0031] During use, the present high-altitude tailwater deep purification system, which utilizes a surface-flow wetland process, first enters the purification trough 1 through the inlet pipe 13. The inlet valve 131 controls the inflow volume and flow rate. During inflow, if the water flow is high, it is diverted through the water pipe 31 at the top of the partition 3 to prevent damage to the soil layer 11 and vegetation caused by the impact of the water flow. Filters 311 at both ends of the water pipe 31 effectively block impurities and prevent clogging.

[0032] The tail water flows in the purification ditch 1 and first passes through the soil layer 11. The microorganisms and plant roots in the soil layer 11 will adsorb, absorb and degrade the suspended matter, nutrients and some organic matter in the tail water. Subsequently, the tail water enters the matrix layer 12 through the mesh plate 2. The matrix layer 12 provides abundant attachment and growth space for microorganisms, further promoting the decomposition of organic matter and the removal of nutrients such as nitrogen and phosphorus. The partition 3 divides the interior of the purification ditch 1 into several planting areas, each of which can be planted with different aquatic plants. These plants further purify the tail water through absorption, interception and degradation of root biofilms. During the purification process, the lifting plate 32 on the partition 3 can be adjusted according to the size of the water flow. When the water flow is large, the lifting plate 32 can be raised to block the water flow, ensuring that the water flow in each planting area is uniform and improving the purification efficiency.

[0033] After being purified by soil layer 11 and matrix layer 12, tailwater is discharged through outlet pipe 14. Outlet valve 141 is used to control the water output and flow rate. Once the effluent meets discharge standards, it can be used for agricultural irrigation, landscape water replenishment, and other purposes, achieving water resource recycling.

[0034] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
