[0017] like Figure 1-7 As shown, an environmentally friendly off-site utilization system and method for spring water includes a spring water source protection device 1, an underground water transmission pipeline 2, an ecological water storage area 3, a siphon pipeline 4, a sedimentation area 7, and a water intake area 8, installed sequentially. The sedimentation area 7 is connected to agricultural irrigation 10 and ecological water replenishment 11, respectively. The water intake area 8 is connected to domestic water 9, which includes a drinking water area, a vegetable washing and rice rinsing water area, and a cleaning water area. The vegetable washing and rice rinsing water area is connected to the agricultural irrigation 10 and the ecological water replenishment 11. The siphon pipeline 4 is connected to a vacuum pump 5, and the vacuum pump 5 is connected to a photovoltaic power generation device 6.

[0018] Specifically, the siphon pipe 4 uses a siphon-type water intake, avoiding the damage to the original water pressure caused by mechanical pumps, and has zero carbon emissions, avoiding noise pollution and oil pollution risks to the water source from equipment such as diesel generators. The vacuum pump 5 is used to create a vacuum, ensuring the smooth operation of the siphon water intake. The electricity used by the vacuum pump 5 is provided by the photovoltaic power generation device 6. The photovoltaic power generation device 6 consists of solar panels, an inverter, a controller, and the vacuum pump 5, among other main components. These components have relatively simple structures and no complex mechanical transmission devices, resulting in high reliability and a low probability of failure. Under normal operating conditions, it can operate stably for many years, reducing downtime and maintenance costs caused by equipment failures. During operation, the photovoltaic power generation device 6 does not produce any pollutants such as carbon dioxide or nitrogen oxides, causing no pollution to the environment and contributing to ecological protection.

[0019] In addition, a pressure sensor (Honeywell 26PC, range 0-10kPa, accuracy ±0.5%) is installed at the inlet of siphon pipe 4. The pressure sensor collects signals and transmits them to the controller (Siemens S7-1200). The controller receives the pressure signal and outputs a PWM signal to control the speed of vacuum pump 5 (400W power, using a variable frequency motor, response frequency 0-50Hz) through a PID algorithm (proportional coefficient Kp=0.8, integral time Ti=30s). When the natural siphon pressure difference is <3kPa (such as when the water level drops during the dry season), the battery switch of the photovoltaic power generation device 6 is automatically activated, driving the vacuum pump 5 to start and maintain the siphon flow rate ≥0.5m³ / h. 3 / h; When the natural pressure difference is ≥5kPa, the vacuum pump 5 automatically stops, relying on natural gravity and pressure difference, the siphon pipeline achieves zero-energy operation. Through dynamic coupling of siphon and photovoltaic, the limitation of traditional siphon relying on a single natural condition is broken, and the siphon system can be stably operated throughout the year, with a comprehensive energy saving rate of >65%.

[0020] Table 1. Verification of Energy Saving Rate Data

[0021] like Figure 2As shown, the spring source protection device 1 includes a spring 101. An ecological buffer zone 102, ≥20m wide, is planted around the spring 101 to prevent hardening of the ground. The ecological buffer zone 102 is surrounded by a protective fence 103 to prevent human activity and animal contamination. Native wetland plants 104 are planted around the protective fence 103 to preserve native vegetation and maintain the original ecological balance. A passageway 105 for personnel access is provided on the protective fence 103, equipped with a gate for maintenance, cleaning, and exploration. The spring 101 is located on a high mountain, while the ecological water storage area 3 is located at a higher elevation below the mountain. The sedimentation area 7 and water intake area 8 are located below the ecological water storage area 3, while domestic water supply 9, agricultural irrigation 10, and ecological water replenishment 11 are located in lower areas.

[0022] like Figure 3 As shown, the ecological water storage area 3 includes a sand and gravel layer 301 at the bottom. The sand and gravel layer 301 has particles of varying sizes, forming numerous pores of different sizes. When water flows through, larger suspended particles, such as silt, leaf fragments, and algae, are intercepted by these pores and cannot pass through the sand and gravel layer, thus achieving preliminary solid-liquid separation and making the water clearer. In addition, some larger microorganisms, such as some protozoa, are also intercepted by the sand and gravel layer 301, reducing the number of microorganisms in the water and lowering the degree of biological pollution. An activated carbon layer 302 is laid on top of the sand and gravel layer 301. The activated carbon layer 302 has a filtering effect to a certain extent, capable of trapping some larger particles or flocs formed during adsorption, further improving the quality of the effluent and making the water clearer. The activated carbon layer 302 allows water to flow more evenly, avoiding short-circuiting or excessive local flow velocity, ensuring the stable operation of the entire purification system and the uniformity of the purification effect. Furthermore, some functional groups on the surface of the activated carbon can chemically react with heavy metal ions in the water, forming chemical bonds or complexes, thereby adsorbing heavy metal ions onto the surface to achieve the purpose of removing heavy metals. For example, it can adsorb heavy metal ions such as mercury, lead, and cadmium in the water, reducing the heavy metal content of the water. In this embodiment, the activated carbon layer 302 uses coal-based columnar activated carbon (particle size 3mm, specific surface area ≥1000m²). 2 With an iodine value ≥900mg / g and a packing thickness of 50cm, and an empty tower flow rate ≤10m / h, the columnar activated carbon can reduce the adverse effects of coal-based activated carbon on water flow to a certain extent, while fully utilizing its adsorption and purification function. The upper layer of the activated carbon layer 302 is a water storage layer.

[0023] The outlet of the underground water pipeline 2 is located within the sand and gravel layer 301. Both the inlet and outlet of the underground water pipeline 2 are fitted with filter screens 304 to block larger particles and prevent blockage of the pipeline.

[0024] like Figure 4 As shown, the sedimentation zone 7 includes a sedimentation tank 703. Two ecological water supply outlet pipes 712 and two agricultural irrigation outlet pipes 713 are installed on the side wall of the sedimentation tank 703. The two ecological water supply outlet pipes 712 are connected to ecological water supply 11, one via overflow and the other via solenoid valve control. The two agricultural irrigation outlet pipes 713 are connected to agricultural irrigation 10, one via overflow and the other via solenoid valve control. Depending on irrigation needs, a suitable irrigation method is selected. For example, if the paddy field needs continuous water, it can be continuously replenished via overflow. When there is a large amount of water in the paddy field, ecological water supply 11 can be added through the overflow outlet. When precise, timed, and quantitative irrigation is required, precise irrigation is achieved by controlling the opening state of the solenoid valve.

[0025] The sedimentation tank 703 has a sludge zone 702 at its bottom for discharging settled sludge. An electric sludge discharge valve (model: AVK 7450) is installed at the bottom of the sludge zone 702, controlled by a time relay (Omron H3CR) to discharge sludge once daily. The sludge discharge valve motor (0.5kW) is driven by a photovoltaic system, and the sludge is transported to a drying area. Several inlets 704 are provided on the side wall of the sedimentation tank 703. The other end of each inlet 704 is connected to a sterilization tank 705. The supernatant water after sedimentation enters the sterilization tank 705 through the inlets 704 for purification. An ultraviolet sterilization device 706 is installed above the sterilization tank 705. Since the ultraviolet sterilization device 706 typically requires a certain water depth to ensure that the ultraviolet rays can fully penetrate the water and effectively kill microorganisms, in this embodiment, the depth of the sterilization tank 705 is lower than that of the sedimentation tank 703, and the width of the sterilization tank 705 is smaller to further ensure the sterilization effect. A filter tank 707, connected by a pipe, is installed on the side of the sterilization tank 705 away from the sedimentation tank 703. The inlet 704 of the sterilization tank 705 is positioned higher than the outlet of the sterilization tank 705 connected to the filter tank 707. Several filter screens are installed inside the filter tank 707. The side of the filter tank 707 away from the sterilization tank 705 is connected to a clear water tank 701 via an outlet pipe. A water outlet 711 for cleaning is installed on the bottom side wall of the sedimentation tank 703.

[0026] The filter device includes a groove 708 installed on the inner wall of the filter tank 707. A filter screen plate 709 is slidably installed in the groove 708, and a handle 710 is installed on the upper surface of the filter screen plate 709. The filter screen plate 709 can be easily replaced by pulling out and installing it using the handle 710. A sealed inspection port (600×600mm, EPDM rubber sealing ring) is added to the top of the filter tank 707, with matching quick-release bolts (304 stainless steel), allowing the filter screen plate 709 to be replaced within 5 minutes.

[0027] like Figure 5 As shown, the water intake area 8 includes a clear water storage tank 801. A water intake trough 805 is installed on one side of the clear water storage tank 801. Several overflow ports 802 are installed on the outer wall of the clear water storage tank 801, and the overflow ports 802 are connected to the water intake trough 805 through overflow pipes 803. Several liquid level adjustment pipes 804 are installed sequentially from top to bottom on the side wall of the clear water storage tank 801. The other end of the liquid level adjustment pipe 804 is connected to the water intake trough 805. The liquid level of the clear water storage tank 801 can be adjusted by opening the valves on the liquid level adjustment pipes 804 at different heights. By adjusting the height of the clear water storage tank 801, the water storage volume in the clear water storage tank 801 can be dynamically controlled to meet people's demand for water during off-peak periods. That is, during periods of low water demand, the water storage volume can be adjusted by closing the valves on different height adjustment pipes 804; during periods of high water demand, the valves on the adjustment pipes 804 can be opened simultaneously to allow water to flow quickly into the water intake tank 805; or, depending on the usage, different height adjustment pipes 804 can be opened selectively to control the water consumption.

[0028] The domestic water system 9 comprises several interconnected pools, roughly divided into three categories: drinking water area, vegetable and rice washing water area, and cleaning water area. The pools are arranged from highest to lowest elevation, with a slope of approximately 1°–2°, ensuring water flows from the drinking water area to the vegetable and rice washing water area, and finally to the cleaning water area, thus conserving water and preventing waste. Furthermore, in this embodiment, the vegetable and rice washing water area can be connected to both agricultural irrigation 10 and ecological water replenishment 11. During agricultural irrigation 10, a water pump is used to supply water as needed, while ecological water replenishment 11 can directly enter through a canal depending on the terrain.

[0029] like Figure 6 , 7As shown, the agricultural irrigation system 10 includes a self-service irrigation system via irrigation canals, as well as a manually controlled irrigation system. This system primarily consists of a main water pipe 1001, on which a water pump 1002 is installed. The water pump 1002 uses a DC brushless motor (1.1kW power) and can be directly driven by a photovoltaic system (5kW modules + 10kWh energy storage). Photovoltaic power generation is prioritized, with the energy storage battery (48V / 100Ah) acting as a buffer. When the energy storage SOC < 20%, the intelligent controller (Morningstar TriStar) switches to mains power, with a switching time < 100ms. In the event of a mains power failure, the energy storage battery can support system operation for 2 hours. The main water pipe 1001 is connected to the branch water pipe 1004 via several tees 1003. Several intermediate pipe supports 1008 and outlet pipes 1005 are installed at equal intervals on the branch water pipe 1004. The intermediate pipe supports 1008 and outlet pipes 1005 are spaced apart, effectively supporting each other to reduce contact between the pipes and the ground, thus preventing ground corrosion and pipe contamination, ensuring irrigation efficiency, and facilitating maintenance. A pipe support 1006 is installed below the outlet pipe 1005, a water spray assembly 1007 is installed at the end of the outlet pipe 1005, and a switch valve 1009 is installed on the outlet pipe 1005.

[0030] The pipe support 1006 includes a support rod 10061. The top of the support rod 10061 has a groove 10062. The width of the groove 10062 is greater than the outer diameter of the water outlet pipe 1005, so that it can hold the water outlet pipe 1005 in place and prevent the water outlet pipe 1005 from shifting its position during irrigation, thus affecting the spraying effect.

[0031] Furthermore, all the aforementioned pipelines use DN50 food-grade PE pipes, and flow meters for testing water flow are installed on the pipelines. Water level sensors and controllers are also installed in each water tank, allowing staff to intuitively understand the operational status of different stages in the environmentally friendly off-site spring water utilization system. For example, the flow rate and volume of water in the ecological storage area 3, siphon pipe 4, sedimentation area 7, and water intake area 8 can be monitored to determine whether the purification process is proceeding according to design requirements and to promptly identify potential blockages or leaks. This helps staff adjust operating parameters in each area based on actual flow conditions, such as controlling the inlet water rate and adjusting the hydraulic retention time, to ensure that microorganisms and plants within the system can exert their optimal purification effect in a suitable environment, thus improving the overall purification efficiency. In addition, by monitoring the outflow of water for different purposes (such as irrigation, domestic water, and ecological water), water resources can be rationally allocated according to actual needs, avoiding waste and improving water resource utilization efficiency.

[0032] An environmentally friendly method for off-site utilization of spring water includes: Step 1: Preliminary assessment and planning; Hydrogeological survey: Determine the spring recharge area and runoff path; Ecological carrying capacity analysis: Assess the impact of water intake on surrounding vegetation and groundwater; Step Two, Construction Phase; Phased Construction: Phase 1: Construction of the spring water source protection device 1. Pipelines will be laid according to the planned route, as follows: The first step is to accurately mark the area to be excavated according to the planned extension path. The second step is to excavate along the marked lines. The third step is to inspect the trench after excavation to ensure that the bottom of the trench is flat and free of stones, hard objects, or other debris that may damage the pipeline. The fourth step is to lower the pipeline into the trench and use a level to level and align the pipeline, ensuring that the pipeline slope meets the design requirements and is controlled at more than 2° to ensure smooth water flow. The fifth step is to backfill and compact the pipeline in layers, using fine soil or sand on both sides and above the pipeline. Phase II: Excavation of ecological water storage area 3, using in-situ earthwork balance, and laying sand and gravel layer 301 and activated carbon layer 302 as required; Phase III: Select an area far from pollution sources and with relatively high downstream terrain to construct sedimentation zone 7 and water intake zone 8. The material used is C30 fine stone concrete with aggregate particle size ≤15mm and 8%-12% expansion agent such as UEA added. The inner surface of the pool is coated with 2mm thick JS polymer cement-based waterproof coating. Phase IV: Distributed terminals; distributed domestic water supply in 9 areas; marking the path of spring water flowing into wetlands and wetland plants, laying 11 ecological water replenishment pipelines; marking the path of spring water flowing into farmland irrigation systems, laying 10 agricultural irrigation pipelines; Step 3: Monitor spring flow and reservoir biodiversity quarterly to assess system sustainability.

An environmentally friendly method for off-site utilization of spring water, based on the environmentally friendly off-site utilization system of claim 1, characterized in that: include: Step 1, Preliminary assessment and planning; Hydrogeological survey: Determine the spring recharge area and runoff path; Ecological carrying capacity analysis: assess the impact of water intake on surrounding vegetation and groundwater; Step Two, Construction Phase; Phased Construction: Phase 1: Construction of the spring water source protection device (1). According to the planned pipeline, the pipeline is laid as follows: The first step is to accurately mark the area to be excavated according to the planned extension path; the second step is to excavate along the marked lines; the third step is to inspect the trench after excavation to ensure that the bottom of the trench is flat and free of stones, hard objects, or debris that could damage the pipes; the fourth step is to lower the pipes into the trench and use a level to level and align the pipes, ensuring that the pipe slope meets the design requirements to guarantee smooth water flow; the fifth step is to backfill and compact the pipes in layers, using fine soil or sand on both sides and above the pipes. Phase II: Ecological water storage area (3) Excavation, in-situ earthwork balance, and laying sand and gravel layer (301) and activated carbon layer (302) as required. Phase III: Select areas far from pollution sources and with high downstream elevations to construct sedimentation zones (7) and water intake zones (8). C30 fine stone concrete with 8%-12% expansion agent is used as the material, and a 2mm thick polymer cement-based waterproof coating is applied to the inner surface of the pool. Phase IV: Distributed terminals; distributed domestic water (9) areas; marked the path of spring water flowing into wetlands and wetland plants, and laid ecological water replenishment (11) pipelines; marked the path of spring water flowing into farmland irrigation systems, and laid agricultural irrigation (10) pipelines; Step 3: Monitor spring flow and reservoir biodiversity quarterly to assess system sustainability.
