[0039] Such as Figures 1-7As shown in the figure, an environmentally friendly off-site utilization system and method for spring water includes a spring source protection device 1, an underground water conveyance pipeline 2, an ecological water storage area 3, a siphon pipeline 4, a sedimentation area 7, and a water intake area 8 installed in sequence. The sedimentation area 7 is respectively connected to agricultural irrigation 10 and ecological water replenishment 11. The water intake area 8 is connected to domestic water 9. The domestic water 9 includes a drinking water area, a vegetable washing and rice washing water area, and a cleaning water area. The vegetable washing and rice washing 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 through a pipeline, and the vacuum pump 5 is connected to a photovoltaic power generation device 6.

[0040] Specifically, the siphon pipeline 4 uses siphon water intake to avoid the damage to the original ecological water pressure by mechanical pump pumping, and has zero carbon emissions, avoiding the noise pollution and oil pollution risks of equipment such as diesel generators to the water source area. The vacuum pump 5 is used to extract vacuum to ensure the smooth progress of siphon water intake. Moreover, the electricity consumed by the vacuum pump 5 is provided by the photovoltaic power generation device 6. The photovoltaic power generation device 6 is composed of main components such as solar panels, inverters, controllers, and the vacuum pump 5. These components have relatively simple structures and no complex mechanical transmission devices, with high reliability and low failure probability during operation. Under normal usage conditions, it can operate stably for many years, reducing the downtime and maintenance costs caused by equipment failures; during operation, the photovoltaic power generation device 6 does not generate any pollutants such as carbon dioxide and nitrogen oxides, is pollution-free to the environment, and is conducive to protecting the ecological environment.

[0041] In addition, a pressure sensor (model Honeywell 26PC, range 0 - 10 kPa, accuracy ±0.5%) is installed at the water inlet of the siphon pipeline 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 rotation speed of the vacuum pump 5 (power 400W, using a variable frequency motor, response frequency 0 - 50 Hz) through the PID algorithm (proportional coefficient Kp = 0.8, integral time Ti = 30 s). When the natural siphon pressure difference < 3 kPa (such as the water level drops in the dry season), the battery switch of the photovoltaic power generation device 6 is automatically started, and the driven vacuum pump 5 starts to maintain the siphon flow rate ≥ 0.5 m 3 / h; when the natural pressure difference ≥ 5 kPa, the vacuum pump 5 automatically shuts down, and relying on natural gravity and pressure difference, the siphon pipeline realizes zero - energy consumption operation. Through the dynamic coupling of siphon - photovoltaic, it breaks through the limitation of traditional siphon relying on a single natural condition, realizes the stable operation of the siphon system throughout the year, and the comprehensive energy - saving rate > 65%.

[0043]

[0044] As Figure 2As shown in the figure, the spring source protection device 1 includes a spring eye 101. An ecological buffer zone 102 is planted around the spring eye 101 with a width ≥ 20m to avoid hardened ground. The outer periphery of the ecological buffer zone 102 is enclosed by a protective fence 103 to prevent human activities and animal pollution. Native wetland plants 104 are planted around the protective fence 103 to retain the original vegetation and maintain the original ecological balance. A passage 105 for people to enter and exit is opened on the protective fence 103, and a switch door is installed on the passage 105 for people to use for maintenance, cleaning, and exploration. The spring eye 101 is located on a mountain with a high terrain. The ecological water storage area 3 is located in a relatively high area at the foot of the mountain. The sedimentation area 7 and the water intake area 8 are located lower than the ecological water storage area 3. Domestic water 9, agricultural irrigation 10, and ecological water replenishment 11 are located in low-lying areas.

[0045] As Figure 3 shown in the figure, the ecological water storage area 3 includes a gravel layer 301 at the bottom. The particle sizes of the gravel layer 301 are different, forming numerous pores of various sizes. When water flows through, larger suspended particles, such as sediment, leaf fragments, algae, etc., will be intercepted by these pores and cannot pass through the gravel layer, thus achieving preliminary solid-liquid separation and making the water body relatively clear. In addition, some larger microorganisms, such as some protozoa, etc., will also be intercepted by the gravel layer 301, reducing the number of microorganisms in the water and the degree of biological pollution. An activated carbon layer 302 is laid on the upper layer of the gravel layer 301. The activated carbon layer 302 has a filtering effect to a certain extent, can intercept some larger particulate matter or flocs formed during the adsorption process, and further improve the water quality of the effluent, making the water clearer. The activated carbon layer 302 can make the water flow through more evenly, avoid situations such as water flow short-circuit or excessive local flow velocity, and ensure the stable operation of the entire purification system and the uniformity of the purification effect. In addition, some functional groups on the surface of the activated carbon can chemically react with heavy metal ions in the water to form chemical bonds or complexes, thereby adsorbing the heavy metal ions on 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 and reduce 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 ≥ 1000m 2 / g, iodine value ≥ 900mg / g), with a filling thickness of 50cm and an empty tower flow velocity ≤ 10m / h, which can reduce the adverse effects of coal-based columnar activated carbon on water flow to a certain extent and at the same time give full play to its role in adsorbing and purifying water quality. The upper layer of the activated carbon layer 302 is a water storage layer.

[0046] The outlet of the underground water conveyance pipeline 2 is located in the gravel layer 301. Filter protection nets 304 are sleeved on both the inlet and outlet of the underground water conveyance pipeline 2 to block some larger particulate impurities and avoid pipeline blockage.

[0047] As shown Figure 4 in the figure, the sedimentation area 7 includes a sedimentation tank 703. There are two ecological water replenishment outlet pipes 712 and two agricultural irrigation outlet pipes 713 arranged on the side wall of the sedimentation tank 703. Among them, the two ecological water replenishment outlet pipes 712 are respectively connected to the ecological water replenishment 11. One ecological water replenishment outlet pipe 712 is connected in an overflow manner, and the other ecological water replenishment outlet pipe 712 is connected in a manner controlled by a solenoid valve. The two agricultural irrigation outlet pipes 713 are respectively connected to the agricultural irrigation 10. One agricultural irrigation outlet pipe 713 is connected in an overflow manner, and the other agricultural irrigation outlet pipe 713 is connected in a manner controlled by a solenoid valve. According to different irrigation requirements, a suitable irrigation method is selected. For example, if there needs to be water in the paddy field all the time, irrigation can be continuously replenished through the overflow method. When there is more water in the paddy field, the ecological water replenishment 11 can be replenished through the overflow port in the paddy field. When precise irrigation at regular intervals and in a fixed quantity is required, precise irrigation operations can be achieved by controlling the opening state of the solenoid valve.

[0048] A sludge area 702 is installed at the bottom of the sedimentation tank 703 for discharging the precipitated sludge. An electric sludge discharge valve (model: AVK 7450) is installed at the bottom of the sludge area 702, and the sludge is discharged once a day through a time relay (Omron H3CR). The sludge discharge valve motor (power 0.5kW) is driven by a photovoltaic system, and the sludge is transported to the drying yard. A number of water inlets 704 are opened on the side wall of the sedimentation tank 703, and the other end of the water inlet 704 is connected to a sterilization tank 705. The clarified water after sedimentation enters the sterilization tank 705 through the water inlet 704 for purification operations. An ultraviolet sterilization device 706 is installed above the sterilization tank 705. Since the ultraviolet sterilization device 706 usually needs to ensure a certain water depth range to ensure that ultraviolet rays can fully penetrate the water body and effectively kill microorganisms in the water, in this embodiment, the depth of the sterilization tank 705 is lower than that of the sedimentation tank 703, and in order to further ensure the sterilization effect, the width of the sterilization tank 705 is smaller. A filter tank 707 connected by a pipeline is installed on one side of the sterilization tank 705 away from the sedimentation tank 703. The height of the position of the water inlet 704 of the sterilization tank 705 is higher than the position of the water outlet connecting the sterilization tank 705 and the filter tank 707. A number of filter net devices are installed in the filter tank 707, and the side of the filter tank 707 away from the sterilization tank 705 is connected to a clear water tank 701 through a water outlet pipeline. A water outlet hole 711 for cleaning is installed on the bottom side wall of the sedimentation tank 703.

[0049] The filter screen device includes a chute 708 installed on the inner side wall of the filter tank 707. A filter screen plate 709 is slidably installed in the chute 708, and a handle 710 is installed on the upper end surface of the filter screen plate 709. The filter screen plate 709 is extracted and installed through the handle 710, which facilitates the replacement of the filter screen. A sealed maintenance opening (size 600×600mm, EPDM rubber seal ring) is added to the top of the filter tank 707, and a quick-release bolt (304 stainless steel) is provided to complete the replacement of the filter screen plate 709 within 5 minutes.

[0050] As Figure 5 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. A number of overflow ports 802 are installed on the outer side wall of the clear water storage tank 801, and the overflow ports 802 are connected to the water intake trough 805 through an overflow pipe 803. A number of liquid level adjustment pipes 804 are installed on the side wall of the clear water storage tank 801 from top to bottom in sequence, and the other end of the liquid level adjustment pipe 804 is connected to the water intake trough 805. By opening the valves on the liquid level adjustment pipes 804 at different heights, the liquid level of the clear water storage tank 801 is adjusted. By adjusting the height of the liquid level in the clear water storage tank 801, the water storage volume in the clear water storage tank 801 is dynamically controlled to meet people's requirements for peak-shaving water demand. That is, during the period with less water demand, the water storage volume can be adjusted by closing the valves on the adjustment pipes 804 at different heights; during the period with more water demand, the valves on the adjustment pipes 804 can be opened simultaneously to allow the water to flow quickly into the water intake trough 805; or the adjustment pipes 804 at different heights can be selectively opened according to the usage situation to control the water consumption.

[0051] Domestic water 9 includes a number of serially connected water tanks, which are roughly divided into three categories: drinking water area, vegetable washing and rice washing water area, and cleaning water area. The heights between adjacent water tanks are arranged from high to low, and the slope is about between 1° and 2°, so that the water flows from the drinking water area to the vegetable washing and rice washing water area, and finally to the cleaning water area, realizing water conservation and avoiding waste of water resources. In addition, in this embodiment, the water in the vegetable washing and rice washing water area can be respectively connected to agricultural irrigation 10 and ecological water replenishment 11. During agricultural irrigation 10, a water pump is used for water supply as needed, and the ecological water replenishment 11 can directly enter through a water channel according to the terrain.

[0052] As Figure 6 、 7As shown, in addition to the canal self-irrigation method, the agricultural irrigation 10 also includes an artificial control irrigation system. The artificial control irrigation system mainly includes a main water pipe 1001, on which a water pump 1002 is installed. The water pump 1002 uses a direct current brushless motor (power 1.1kW) and can be directly driven by a photovoltaic system (5kW module + 10kWh energy storage). Photovoltaic power generation is preferentially used, and the energy storage battery (48V / 100Ah) is used as a buffer; when the energy storage SOC < 20%, the intelligent controller (Morningstar TriStar) switches to the commercial power, and the switching time < 100ms; when there is a commercial power failure, the energy storage battery can support the system operation for 2 hours. The main water pipe 1001 is connected to a branch water pipe 1004 through a number of tees 1003. A number of intermediate pipeline supports 1008 and water outlet pipes 1005 are equidistantly installed on the branch water pipe 1004. The intermediate pipeline supports 1008 and the water outlet pipes 1005 are distributed at intervals, and the effective support can reduce the contact between the pipeline and the ground, thereby avoiding ground corrosion and pipeline pollution, ensuring irrigation efficiency and facilitating maintenance. A pipe support 1006 is installed below the water outlet pipe 1005, a water spraying assembly 1007 is installed at the end of the water outlet pipe 1005, and a switch valve 1009 is installed on the water outlet pipe 1005.

[0053] The pipe support 1006 includes a support rod 10061, and a groove 10062 is formed at the top of the support rod 10061. The width of the groove 10062 is greater than the outer diameter of the water outlet pipe 1005, so as to clamp the water outlet pipe 1005 and prevent the water outlet pipe 1005 from shifting during irrigation, affecting the spraying effect.

[0054] In addition, DN50 food-grade PE pipes are used for all the above pipelines, and a flowmeter for testing water flow is also installed on the pipelines. A water level sensor and a controller are installed in each water tank, which is convenient for the staff to intuitively understand the operating conditions of different links in the environmental protection type spring water off-site utilization system, such as the flow velocity and flow rate of water flow in the ecological storage area 3, the siphon pipeline 4, the sedimentation area 7, the water intake area 8, etc., to judge whether the purification process is carried out according to the design requirements, and to timely discover possible problems such as blockage and leakage; it helps the staff to adjust the operating parameters of each area according to the actual flow conditions, such as controlling the water inlet speed and adjusting the hydraulic retention time, etc., to ensure that microorganisms, plants, etc. in the system can play the best purification role in a suitable environment and improve the overall purification effect; in addition, by monitoring the water outlet flow rates for different uses (such as irrigation, domestic water, ecological water, etc.), the water resources can be reasonably allocated according to the actual needs, avoiding waste and improving the utilization efficiency of water resources.

[0055] An environmental protection type spring water off-site utilization method includes:

[0056] Step 1: Preliminary assessment and planning; Hydrogeological survey: determine the spring water recharge area and runoff path; Ecological carrying capacity analysis: assess the impact of water extraction on surrounding vegetation and groundwater;

[0057] Step 2, construction phase; construction in stages:

[0058] Phase I: Construction of spring water source protection device 1. Pipeline laying according to the planned pipeline. The pipeline laying is as follows:

[0059] The first step is to accurately mark the area that needs to be excavated according to the planned extension path; the second step is to excavate along the marked line; the third step is to check the trench after the excavation is completed to ensure that the bottom of the trench is flat and there are no 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 to ensure that the slope of the pipeline meets the design requirements and the slope is controlled at more than 2° to ensure smooth water flow; the fifth step is to backfill fine soil or sand on both sides and above the pipeline by layered backfilling and layered compaction;

[0060] Phase II: excavation of ecological water storage area 3, using in-situ earthwork balance, laying gravel layer 301 and activated carbon layer 302 as required;

[0061] Phase III: Select an area far from pollution sources and with relatively high terrain downstream to build sedimentation area 7 and water intake area 8. The material used is C30 fine stone concrete with aggregate size ≤15mm and 8%-12% expansion agent such as UEA. The inner surface of the pool is coated with 2mm thick JS polymer cement-based waterproof coating;

[0062] Phase IV: Distributed terminals; distribute domestic water in 9 areas; mark the path of spring water flowing into the wetland and wetland plants, and lay 11 ecological water replenishment pipelines; mark the path of spring water flowing into the farmland irrigation system, and lay 10 agricultural irrigation pipelines;
