Description

Technical Field

[0001] The present invention belongs to the technical field of water environment improvement and management, and in particular relates to a system and method for improving water transparency by filtering a natural gravel layer. Background Art

[0002] Water transparency is one of the important indicators for measuring water quality. It directly reflects the content of suspended matter, dissolved matter, colloids and other substances in the water. Highly transparent water means low impurities in the water and clear water quality, which is conducive to the survival and reproduction of aquatic organisms, and also provides a better leisure and entertainment environment for humans. However, natural water bodies, such as lakes, rivers and reservoirs, are often affected by various pollution sources, resulting in a decrease in water transparency, affecting water quality and ecological environment.

[0003] In order to improve the transparency of water bodies, although there are many methods to improve the transparency of water bodies in the prior art, each method has its limitations.

[0015] Figure 1 It is a schematic diagram of the system structure in the present invention; Figure 2 It is a schematic diagram of the system structure of another embodiment of the present invention.

[0016] Figure 1 and Figure 2 The labels are: filtering unit 1, water lifting unit 2, pump body 21, delivery pipeline 22, flow rate sensor 3, riverside treatment unit 4, pumping unit 5, water storage part 51, water pump 52, delivery pipeline 53, liquid level sensor 6, riverbed 7, and shore soil 8. DETAILED DESCRIPTION

[0017] Example 1 like Figure 1 As shown, this embodiment provides a water transparency enhancement system utilizing natural gravel layer filtration, comprising: a filtration unit 1, a water extraction unit 2, and a monitoring unit.

[0018] The filter unit 1 is installed in the riverbed 7; the filter unit 1 is used to filter the water passing through. The number of the filter units 1 is set based on actual needs, such as two groups, three groups, etc.; this embodiment is described as a group of filter units 1. The filter unit 1 has an input end and an output end.

[0019] The arrangement position of the filter unit 1 can be horizontal, inclined, or vertical; preferably, it is arranged vertically, with the input end at the top and the output end at the bottom.

[0020] Along the water flow direction ( Figure 1The direction indicated by the arrow in the middle is the direction of water flow). Multiple layers of natural gravel filter layers with gradually decreasing particle sizes are sequentially arranged in the filter unit 1; in other words, in this embodiment, multiple layers of natural gravel filter layers are arranged from top to bottom in the filter unit 1, and the particle size of the natural gravel filter layer becomes smaller as the layers are arranged downward. The natural gravel layer is a natural filter medium. When water flows through the gravel layer, larger particles will directly collide with the gravel surface and be intercepted; smaller particles will be dispersed to the gravel surface and adhered to under the action of Brownian motion.

[0021] The water pumping unit 2 includes a pump body 21 connected to the output end, and a delivery pipeline 22 connected to the pump body 21 at one end. The other end of the delivery pipeline 22 extends vertically upward to the desired water delivery position; for example, the filtered water is scattered into the original water body in the form of a fountain through the delivery pipeline 22. The pump body 21 is configured as a variable frequency water pump. The pump body 21 is configured to include at least the following working modes: a steady-state operation mode and a rapid response mode. The working power of the pump body 21 in the rapid response mode is greater than the working power in the stable operation mode.

[0022] The monitoring unit includes a flow rate sensor 3 installed between the filter unit 1 and the pump body 21, and multiple groups of turbidity sensors arranged in the water body. The flow rate sensor 3 is used to obtain the flow rate of the filtered water body. The turbidity sensor is used to obtain the turbidity data of the water body. The turbidity data of the water body is obtained by the turbidity sensor, and the water transparency improvement scene is divided into: conventional scene and emergency scene based on the turbidity data. In this embodiment, the scene where the turbidity of the water body is relatively stable and does not change much is set as a conventional scene, such as sunny days, cloudy days and other weather, the water body does not flow much, and there are few external factors that affect the turbidity (soil or other particles) input. The scene where the turbidity of the water body changes greatly is set as an emergency scene, such as heavy rain weather, the turbidity of the water body will change significantly; heavy rain will cause the surface water flow to accelerate, and the soil and other particles will be washed into the water body, thereby increasing the turbidity of the water.

[0023] Based on the water transparency improvement scenario, the corresponding working mode of the pump body 21 is set: in the normal scenario, the steady-state operation mode is selected; in the emergency scenario, the rapid response mode is selected. Under the action of the pump body 21, the water to be treated flows from the input end to the inside of the filter unit 1, and is filtered and processed by the multiple layers of natural gravel filter layers, and finally transported from the delivery pipeline 22 to the corresponding water delivery location (such as the original water body).

[0024] In the above technical solution, the natural gravel filter layer can effectively remove suspended matter, organic matter and some microorganisms in the water body, thereby significantly improving the transparency of the water body and making the water body look clearer; this method belongs to physical filtration, and will not introduce new chemicals into the water body, thus avoiding the risk of secondary pollution that may be caused by chemical treatment. In addition, the above technical solution adjusts the working mode according to the turbidity of the water body to ensure that energy is saved to the maximum extent while maintaining the filtering effect. In conventional scenarios, the pump body 21 can meet the filtering requirements by adopting a steady-state operation mode, avoiding unnecessary energy waste. The rapid response mode is usually used to treat water bodies with high turbidity, while the steady-state operation mode is adopted when the turbidity is low, which can reduce the wear and load of the equipment and thus extend its service life. By flexibly adjusting the working mode, it is ensured that the best filtering effect can be achieved under different turbidities. This helps to maintain the cleanliness and transparency of the water body and reduce environmental problems caused by pollution.

[0025] In a further embodiment, Figure 2 As shown, the above system also includes: a riverside treatment unit 4, a pumping unit 5, and a liquid level sensor 6. The riverside treatment unit 4 is installed in the shore soil 8 on the side of the water body. The riverside treatment unit 4 can be arranged in several groups along the length direction of the shore soil 8. In this embodiment, a group of riverside treatment units 4 is used as an example for explanation. The riverside treatment unit 4 includes N groups of purification modules stacked in sequence along the vertical direction. The interior of the purification module is provided with multiple layers of natural gravel filtration layers with gradually decreasing particle sizes along the flow direction of the water body; as shown in FIG. Figure 1 As shown, the water flow direction inside the purification module is set as indicated by the arrow.

[0026] The water pumping unit 5 includes a water storage member 51 communicating with each purification module, a water pump 52 connected to the water storage member 51 , and a delivery pipeline 53 connected to the water pump 52 .

[0027] The liquid level sensor 6 is installed in the water storage member 51 ; the liquid level sensor 6 is configured to obtain the height of the treated water in the water storage member 51 .

[0028] During use, when the height of the treated water in the water storage member 51 reaches a predetermined height, the water pump 52 is set to work to transport the water in the water storage member 51 to a predetermined location (such as the original water body).

[0029] The riverside treatment unit 4 is set up to supplement the above-mentioned filtering unit 1. The water filtered in the riverside treatment unit 4 comes from the horizontal flow of the water body. When the shore soil 8 of the water body is a soil with strong water permeability, such as sandy soil and loam, especially during heavy rain, the water level of the water body rises and the turbidity becomes larger; because there will be a horizontal flow process in the shore soil 8, the water body must not only be directly filtered by the filtering unit 1, but also supplemented by the riverside treatment unit 4.

[0030] In the above technical scheme, when the degree of horizontal flow in the shore soil 8 is large, the purification module in the riverside treatment unit 4 is used to effectively remove suspended matter in the horizontally flowing water body, adsorb pollutants such as organic matter and heavy metals in the horizontally flowing water body, and further purify the water quality; through the filtering effect of the purification module, the pollutants or harmful substances entering the soil are reduced, the stability of the soil is protected, and the negative impact of soil pollution on plant growth and groundwater is avoided.

[0031] Example 2 This embodiment provides a method for improving water transparency based on the above-mentioned natural gravel layer filtration system (hereinafter referred to as the method), comprising the following steps: Step S1, obtaining historical turbidity data about the water body to be treated, and dividing the water body transparency improvement scenarios into: conventional scenarios and emergency scenarios based on the historical turbidity data; based on the conventional scenarios and emergency scenarios, determining the standard flow rate range of the filtered water body, and calculating the working power range of the pump body based on the standard flow rate range.

[0032] In various weather conditions such as sunny days, cloudy days, and rainstorms, the turbidity data of the water body to be treated (i.e., the water body that needs to improve transparency) is collected in different time periods, and these turbidity data are used as historical turbidity data. The historical turbidity data is analyzed to obtain the degree of turbidity change, which is divided into regular scenes or emergency scenes. For example, under normal circumstances, the turbidity changes on sunny and cloudy days are relatively small, and the turbidity fluctuation rate is low, such as -10%~10%. The turbidity of rainstorms may rise sharply by hundreds of times or even higher, and the turbidity fluctuation rate is relatively high, such as 2000%~4900%. The floating threshold is confirmed based on the above floating rate. The scene exceeding the floating threshold is set as an emergency scene, and the scene within the floating threshold is set as a regular scene.

[0033] Predefine the standard range of flow rate of filtered water, such as Based on the standard flow rate range, calculate the working power range of the pump body as the power source. The working power of the pump body is calculated using the following formula: ; In the formula, is the working power of the pump body, is the cross-sectional area of ​​the pipe, is the flow rate of the filtered water, It is the height to which the pump lifts the filtered water. , is the adjustment factor, is the pump efficiency.

[0034] The endpoint values , Substitute the above formula to calculate the end point value of the pump's working power. , Compared with conventional scenarios, emergency scenarios require faster water filtration, so The flow rate ranges of the filtered water bodies are different for emergency scenarios and regular scenarios, and the flow rate range of the emergency scenario is greater than the flow rate range of the regular scenario. Based on the flow rate range requirements of the filtered water bodies in different emergency scenarios and regular scenarios, the working power of the pump body is adjusted.

[0035] Step S2, obtaining the current turbidity change value of the water body to be treated, and selecting a conventional scenario or an emergency scenario based on the current turbidity change value; adjusting the working mode of the pump body to a steady-state operation mode or a rapid response mode based on the conventional scenario or the emergency scenario.

[0036] In the above technical solution, in actual use, by obtaining the current turbidity change value of the water body to be treated, the corresponding normal scene or emergency scene is selected, and the working mode of the pump body is adaptively adjusted. After the pump body is turned on, the water body flows into the filter unit, is filtered by the filter unit, and is transported to the water body delivery position by the delivery pipeline.

[0037] As the filter unit is used for a longer time, impurities and particles will gradually accumulate inside it, resulting in reduced filtration efficiency and even blockage. If the blocked filter box is not predicted and replaced in time, the pumping efficiency of the pump body will be seriously affected, which may cause poor water flow or slow pumping speed. In order to solve this problem, step S3 is proposed.

[0038] Step S3, continuously record the current flow rate of the filtered water body and the working status data of the pump body; predict the blockage condition of the filter unit according to the change of the current flow rate and the working status data; adjust the filter unit based on the blockage condition of the filter unit.

[0039] Further, predicting the clogging condition of the filter unit in step S3 includes the following steps: Based on the working status data, it is determined whether the pump is in a normal working state. If it is determined to be yes, the following steps are performed: Determine whether the change of the current flow rate meets the flow rate change condition, and obtain a determination result: if so, it is determined that the filter unit has a risk of clogging; otherwise, it is determined that the filter unit has no risk of clogging; The flow rate change condition is that the current flow rate decreases within a unit time until it drops to a flow rate threshold range, and the current flow rate maintains a stable change within the flow rate threshold range.

[0040] In the above technical solution, the current flow rate data of the filtered water body and the working status data of the pump body are continuously and real-timely acquired and recorded. First, the working status data of the pump body is used to determine whether the pump body is in a normal working state. If it is not in a normal working state, the pump body is replaced in time. If the pump body is in a normal working state, the current flow rate data of the filtered water body is further used to determine whether the filter unit is blocked. The working status data of the pump body can be acquired and determined through a flow sensor, a pressure sensor, a vibration sensor, or a temperature sensor. The determination of the working status of the pump body adopts the existing technology, and the specific steps are not repeated here.

[0041] The following uses specific data to illustrate the process of determining whether the filter unit is blocked: The filter unit is connected to the pump body. When the filter unit is not blocked, the flow rate of the pump body water inlet is m / s. When the filter box is clogged, the flow rate will change. Flow rate change after clogging: Mild blockage: flow rate decreases by about 10%, i.e. = × (1 - 0.1).

[0042] Moderate blockage: flow rate decreases by about 30%, i.e. = × (1 - 0.3).

[0043] Severe blockage: flow rate is reduced by about 50%, that is = × (1 - 0.5).

[0044] If the current flow rate of the test unit is decreasing and decreasing to a certain extent, the flow rate is within the flow rate threshold range (such as 0~0.5 ) within a stable range, the filter unit is considered blocked. Based on actual needs, different blockage levels and flow rate threshold ranges corresponding to the blockage levels are set; based on different blockage levels, different filter unit adjustment plans are formulated.

[0045] By monitoring the flow rate changes of the filtered water, the blockage of the filter unit can be grasped in real time; when the flow rate drops to a certain level, an early warning signal can be issued to prompt the operator to take timely measures. When the blockage is not serious, by cleaning or replacing the filter unit, the blockage can be effectively prevented and damage to the pump body and water treatment system can be avoided. According to the data of flow rate changes, a reasonable maintenance plan can be formulated to ensure the regular cleaning and replacement of the filter unit. By predicting the blockage, maintenance can be carried out before complete blockage occurs, thereby reducing downtime caused by blockage. By timely cleaning or replacing the blocked filter unit, the flow rate at the water inlet of the pump body can be kept stable to ensure the normal operation of the water treatment system.

[0046] Furthermore, the method further comprises the following steps: In an emergency scenario, the current turbidity of the water body is obtained; based on the current turbidity, the current power of the pump body is adjusted to make the pump body enter a rapid response mode; After the current turbidity of the water body decreases to a predetermined range, the working state of the pump body is controlled to change from the fast response mode to the steady-state working mode.

[0047] In the above technical solution, in emergency scenarios, the pump efficiency is increased to quickly increase the discharge volume, effectively coping with the increase in water turbidity in a short period of time; after the turbidity drops to a predetermined range (based on actual conditions), the pump efficiency is reduced in a timely manner to avoid unnecessary energy consumption and optimize the treatment and utilization of water resources.

[0048] Furthermore, the method further comprises the following steps: In a conventional scenario or an emergency scenario, the water to be treated flows into each purification module and is treated; the treated water flows into the water storage unit; The current height of the treated water in the water storage part is obtained, and it is determined whether the current height meets the height threshold range. If it is determined to be yes, the treated water in the water storage part is transported to a predetermined position by using a water pump.

[0049] In the above technical solution, the phenomenon of water flowing horizontally toward the shore soil will occur in both conventional and emergency scenarios. Therefore, the water to be treated flows into each purification module for filtration and treatment, and the filtered water flows into the water storage part. A liquid level sensor is set in the water storage part to obtain the current height of the treated water in the water storage part in real time. When the current height meets the height threshold range (based on actual needs, such as 40cm~2m), the water is pumped out of the water storage part by using a pump. When the water height does not reach the height threshold range, not activating the pump can avoid unnecessary energy consumption and reduce the operating cost of the equipment. The pump is activated only when needed to ensure the rational use of energy and avoid waste.

[0050] Furthermore, the method further comprises the following steps: Obtaining the current height change of the water body being treated in the water storage component, determining whether the current height change meets the height change condition, and obtaining a determination result. If so, determining that the purification module has a blockage risk; otherwise, determining that the purification module has no blockage risk; The altitude change condition is that the change difference of the current altitude within a unit time period is less than the altitude difference threshold range.

[0051] In the above technical solution, after a long period of filtration, the natural gravel layer in the purification module will also face the risk of clogging, so it is also necessary to timely predict the clogging of the purification module. Therefore, the height change in the water storage part is used to predict whether the purification module is at risk of clogging. If the height difference of the treated water body in the water storage part changes within a unit time period is less than the height difference threshold range, that is, the change is small, it means that the purification module is at risk of clogging, and the natural gravel layer in the purification module needs to be replaced in time.
