Description

Technical Field

[0001] This invention relates to the field of natural spring water resource extraction technology, specifically to a stratified selection and collection process for natural spring water resources, used for in-situ stratified water extraction from spring water sources and homogenization of water quality to ensure the consistency of water quality across batches of mass-produced spring water. Background Technology

[0002] Natural spring water is formed by seepage from fissures in multiple underground rock strata, with significant differences in mineral and ion content at different depths. Current spring water extraction methods often involve concentrated water intake from a single shallow spring. Influenced by rainfall, groundwater levels, and seasonal temperatures, the supply of shallow groundwater fluctuates considerably, leading to significant variations in raw water TDS, calcium and magnesium ion levels, and bicarbonate concentrations. This results in noticeable differences in the quality of finished water from batch to batch, making it difficult to maintain consistent quality. Some manufacturers attempt to balance water quality by artificially adding inorganic salts, contradicting the product's positioning as natural spring water without external additives. A few stratified extraction methods simply store the water separately, lacking a real-time water quality monitoring and blending mechanism. This prevents automatic adjustment of water intake from each stratum based on dynamic changes in the water source, resulting in inconsistent batch quality. Therefore, a spring water extraction process that enables in-situ stratified selection, dynamic blending, and stable homogeneous water extraction is urgently needed. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing methods for collecting water from single mountain springs, such as large fluctuations in water quality, poor batch consistency, and reliance on artificial conditioning. This invention provides a stratified selection and collection process for natural mountain spring water resources. Through vertical stratified collection, real-time online water quality monitoring, and stratified flow rate linkage, the process achieves homogenization of natural water bodies at the source, eliminating the need for subsequent artificial conditioning and ensuring stable and consistent water quality indicators for each batch of mountain spring water produced continuously.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A stratified selection and collection process for natural mountain spring water resources is characterized by the in-situ vertical stratification of water intake units at the mountain spring source, collecting spring water from different rock strata, and dynamically adjusting the water intake flow rate of each layer after online water quality testing to achieve constant raw water quality. Specifically, it includes the following steps: Step 1, stratified exploration and well placement in the source area: Vertical strata are surveyed in sections in the mountain spring outcrop area, dividing the area into three water intake layers: shallow weathered rock layer, medium-layer fractured rock layer, and deep bedrock aquifer; within the same spring... The system involves three steps: Step 1: Vertically descending multi-layered water intake wells are constructed within the area, with each layer having its own independently installed sealed water intake pipeline and a separate flow control valve. Step 2: Independent layered water collection and storage: Each layer's water intake pipeline is connected to a corresponding independent sealed raw water storage chamber. These chambers are not interconnected, ensuring that the mountain spring water from each layer is stored separately, preventing pre-mixing of water from different strata. Step 3: Real-time online monitoring of layered water quality: Online monitoring modules are installed at the outlet of each storage chamber to monitor the water's TDS, calcium, magnesium, bicarbonate, and pH levels in real time. Four core indicators, with data uploaded to the central control system in real time; Step 4, Layered flow linkage and homogenization collection: The central control system compares the detection data of each layer of water with the preset standard water quality range, automatically adjusts the opening of the flow regulating valve of each layer of pipeline, matches the output ratio of shallow, middle and deep raw water, and the multi-layer water bodies converge and mix synchronously to form homogenized and stable mountain spring raw water; Step 5, Homogenized raw water pressure stabilization and transportation: The homogenized mountain spring raw water after proportioning and mixing enters the pressure stabilization and equalization tank, is allowed to stand at low speed for 30-60 minutes to homogenize and blend, eliminate instantaneous proportion fluctuations, and then is transported to the downstream filtration and bottling process.

[0006] Furthermore, in step 1, the depth of the three water intake layers is divided as follows: the shallow water intake layer has a depth of 3-8m, the middle water intake layer has a depth of 10-20m, and the deep bedrock water intake layer has a depth of 22-40m. The pipe wall of each water intake well is opened with permeable filter holes of corresponding depth, and the outside is wrapped with a multi-level filter material layer to block mud, sand and rock debris.

[0007] Furthermore, in step 3, the online monitoring module completes a set of water quality data acquisition every 30 seconds and synchronizes it to the PLC central control system in real time.

[0008] Furthermore, step 4 presets the standard water quality range: TDS 60~120mg / L, pH 7.2~7.8, calcium ions 12~28mg / L, magnesium ions 3~10mg / L; when the water quality index of a certain layer is too high / too low, the central control automatically reduces / increases the water intake flow rate of that layer.

[0009] Furthermore, in step 5, a spiral turbulence buffer structure is installed inside the pressure stabilizing and equalizing tank to promote the full and uniform mixing of multiple layers of water.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Source selection is layered to preserve natural properties: original mountain spring water is collected in layers according to the depth of underground rock strata, without damaging the seepage structure of the strata. No artificial minerals or regulators are added throughout the process, and the finished product is natural mountain spring water.

[0012] Dynamic blending ensures high consistency in water quality across batches: By relying on real-time online water quality monitoring and automatic flow adjustment, fluctuations in water quality at a single layer caused by rainfall, water level, and seasons are offset. Under continuous production, the fluctuation range of TDS and mineral indicators of each batch of raw water is controlled within ±5%, which is far superior to traditional single-point water intake.

[0013] Layered independent water storage, flexible regulation: The three water bodies are temporarily stored separately, and the ratio can be adjusted according to market demand to flexibly produce two specifications of mountain spring water, namely low-mineralized and medium-mineralized, with strong production adaptability.

[0014] Reduce the load on downstream water treatment: Water quality homogenization is completed at the source, eliminating the need for complex post-treatment processes, simplifying the downstream filtration production line, and reducing investment in water quality conditioning equipment.

[0015] Balanced and stable water resource utilization: Deep and shallow water sources complement each other, deep water sources replenish shallow water during the dry season, and shallow water sources dilute highly mineralized deep water bodies during the rainy season, resulting in a significant improvement in the annual water intake and water quality stability.

[0017] Example 1:

[0018] Step 1: Mountain spring strata exploration and division into three water intake layers: shallow layer 5m, middle layer 15m, and deep layer 30m. Each layer is independently laid with stainless steel water intake pipes, and the outside of the pipes is filled with quartz sand filter material to block mud and sand.

[0019] Step 2: The three water intake pipes are respectively connected to the No. 1, No. 2 and No. 3 sealed 316L stainless steel temporary storage tanks for separate water storage;

[0020] Step 3: Install online water quality monitoring instruments at the outlet of each compartment, collect TDS, calcium and magnesium ion, and pH data every 30 seconds and transmit them to the PLC central control.

[0021] Step 4: The preset standard TDS range is 80-100 mg / L. The TDS of the shallow raw water is 62 mg / L, the middle layer is 95 mg / L, and the deep layer is 145 mg / L. The central control automatically adjusts the flow ratio of shallow layer: middle layer: deep layer = 3:5:2 and mixes them synchronously.

[0022] Step 5: The mixed water is sent to a pressure stabilizing and equalizing tank and allowed to stand for 45 minutes with spiral turbulence. After homogenization, it is transported to the downstream processing. The TDS of the finished product is stable at 88-96 mg / L for 72 consecutive hours, with no significant difference between batches.
