BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic flow chart of a method for monitoring, warning of quantity and quality of rural drinking water safety proposed by the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0018] The following describes the specific embodiments of the present invention to facilitate those skilled in the art of the present technology to understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of the present technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are within the scope of protection.

[0019] As Figure 1 shown, a method for monitoring, warning of quantity and quality of rural drinking water safety includes the following steps S1-S6:

[0020] S1. Obtain the water source of rural drinking water and the upstream area of the water source, and collect the water quality monitoring data of the water source and the water quality monitoring data of the upstream area; wherein, the water quality monitoring data includes pH value, temperature, dissolved oxygen, conductivity and turbidity.

[0021] Specifically, step S1 specifically includes: obtaining the water source of rural drinking water and the upstream area of the water source, respectively dividing the water source and the upstream area of the water source into uniform grids, and collecting the water quality monitoring data of the water source and the water quality monitoring data of the upstream area by arranging a water quality sensor group at the center of each grid.

[0022] In this embodiment, the water supply source for rural drinking water is the area that directly provides water sources for rural users; the upstream area of the water supply source is the upstream part of the water flow direction of the water supply source; since the water quality condition upstream of the water supply source will affect the water quality of the water supply source, the water quality of the water supply source for rural drinking water and the upstream area of the water supply source are respectively monitored, so as to conduct quality and quantity monitoring and early warning of rural drinking water safety subsequently. In addition, the purpose of respectively dividing the water supply source and the upstream area of the water supply source into uniform grids is to ensure that each grid covers a certain spatial range, so as to obtain accurate water quality monitoring data, and at the same time facilitate subsequent obtaining of accurate areas with unqualified water quality, and can specifically process the areas with unqualified water quality to reduce labor costs and calculation amounts. Among them, the water quality sensor group includes sensors for monitoring pH value, temperature, dissolved oxygen, conductivity, and turbidity.

[0023] S2. Obtain the drinking water pipeline data of rural drinking water.

[0024] Specifically, step S2 specifically includes: installing pressure sensors and flow sensors at the starting point, midpoint, and end point positions of the drinking water pipeline of rural drinking water respectively, and collecting the water pressure data and water flow data of the drinking water pipeline.

[0025] In this embodiment, the purpose of collecting the drinking water pipeline data of rural drinking water is to facilitate subsequent steps to judge whether the drinking water pipeline is aging, so as to judge whether the abnormality of the water quality monitoring data of rural drinking water is related to the aging of the water pipe.

[0026] S3. Judge whether the water quality monitoring data of the upstream area is abnormal. If so, repair the water quality of the upstream area; otherwise, execute step S4.

[0027] In this embodiment, the purpose of judging whether the water quality monitoring data of the upstream area is abnormal is that since the water quality condition upstream of the water supply source will affect the water quality of the water supply source, first judge whether the upstream water quality is abnormal. If the upstream is abnormal, trigger the early warning mechanism and repair the water quality of the upstream area.

[0028] Specifically, the specific process of judging whether the water quality monitoring data of the upstream area is abnormal in step S3 is as follows:

[0029] According to the water quality monitoring data of the upstream area, calculate the water quality pollution index of the upstream area, that is:

[0030]

[0031] Among them, NPI is the water quality pollution index of each grid in the upstream area, C i represents the i-th water quality monitoring data of each grid in the upstream area, S i represents the standard value of the i-th water quality monitoring data of each grid in the upstream area, Represents the maximum value of all water quality monitoring data for each grid in the upstream area. Represents the average value of all water quality monitoring data for each grid in the upstream area.

[0032] Determine whether the water quality pollution index in the upstream area is greater than the water quality standard threshold. If so, the water quality meets the standard; otherwise, the water quality is abnormal.

[0033] In this embodiment, the water quality pollution index in the upstream area is the Nemerow pollution index. That is, by calculating the Nemerow pollution index of each grid in the upstream area, it is determined whether the water quality of each grid meets the standard, so as to obtain the grids with unqualified water quality and the areas with unqualified water quality, so as to perform water quality restoration on the areas with unqualified water quality in the subsequent steps. Among them, the water quality standard threshold is 1.

[0034] Specifically, the specific process of water quality restoration for the upstream area in step S3 is as follows:

[0035] Based on the water quality pollution index in the upstream area, obtain the grids with unqualified water quality in the upstream area, and generate the areas with unqualified water quality in the upstream area; for the areas with unqualified water quality in the upstream area, introduce a water quality restoration mechanism to restore the water quality of the areas with unqualified water quality in the upstream area.

[0036] Specifically, the water quality restoration mechanism is as follows:

[0037] If the dissolved oxygen in the area with unqualified water quality is lower than the water quality dissolved oxygen standard value, use aeration equipment to inject oxygen into the area with unqualified water quality.

[0038] In this embodiment, injecting oxygen into the area with unqualified water quality using aeration equipment is aeration restoration, which is carried out for the area with insufficient dissolved oxygen, so as to increase the dissolved oxygen concentration and promote the self-purification ability of the water body. Among them, the oxygen injection amount is: ΔDO = K(C s - C0), ΔDO is the increase or injection amount of dissolved oxygen, K is the aeration efficiency coefficient, and this coefficient is related to the type of aeration equipment and water body conditions, C s is the saturated dissolved oxygen concentration, which is related to temperature, C0 is the current dissolved oxygen concentration; therefore, based on the oxygen injection amount, the target concentration C target of the final dissolved oxygen is: C target = C0 + ΔDO to ensure that C target ≥ 5mg / L.

[0039] If the PH value of the area with unqualified water quality is an acidic water body, put alkaline substances into the area with unqualified water quality to neutralize the acidity. If the PH value of the area with unqualified water quality is an alkaline water body, put acidic substances into the area with unqualified water quality to neutralize the alkalinity.

[0040] In this embodiment, the water body with a pH value of less than 6.5 is an acidic water body, and the water body with a pH value of greater than 8.5 is an alkaline water body. Therefore, if the pH value is too low, alkaline substances such as limestone and sodium bicarbonate (which are highly safe) can be added to neutralize the acidity. If the pH value is too high, acidic substances such as citric acid (which is highly safe) can be added to neutralize the alkalinity. Among them, the safety of drinking water needs to be considered to select the acidic or alkaline substances to be added, and the dosage of the added substances also needs to be considered.

[0041] If the temperature in the area with substandard water quality is too low, solar energy equipment can be installed at the boundary of the area with substandard water quality to increase the heat source input, or the reservoir water discharge frequency can be reduced to reduce the cold water input. If the temperature in the area with substandard water quality is too high, trees can be planted at the boundary of the area with substandard water quality to reduce the temperature by increasing the shade of the water body.

[0042] In this embodiment, the excessively high water temperature of the water body may be caused by industrial cooling water discharge or climate warming, and the excessively low water temperature may be caused by cold water discharge or cold climate. Therefore, for the restoration of the water body temperature, if the temperature is too high, solar energy can be installed on both sides of the area where the water body temperature does not meet the standard to increase the heat source input of the water body, or the reservoir water discharge strategy can be adjusted to reduce the cold water input by reducing the reservoir water discharge frequency. If the temperature is too high, trees can be planted at the boundary of the area where the water quality does not meet the standard to increase the shade of the water body, thereby reducing the temperature.

[0043] If the conductivity of the water quality in the area with substandard water quality is too high, clean water is introduced to dilute the high-salinity water body.

[0044] In this embodiment, the excessively high conductivity of the water body is generally caused by excessive dissolved salts such as sodium ions and chloride ions. Therefore, clean water can be introduced to dilute the high-salinity water body, thereby reducing the conductivity of the water body.

[0045] If the turbidity of the water quality in the area with substandard water quality is too high, flocculants are added to precipitate the suspended particles.

[0046] In this embodiment, the turbidity of the water body is usually caused by excessive suspended particles such as sediment and algae. Generally, flocculants can be added to precipitate the suspended particles, or sand filtration or membrane filtration can be used to remove the suspended particles.

[0047] S4. Determine whether the water quality monitoring data of the water delivery source is abnormal. If so, repair the water quality of the water delivery source; otherwise, execute step S5.

[0048] Specifically, the specific process of determining whether the water quality monitoring data of the water delivery source is abnormal in step S4 is as follows:

[0049] According to the water quality monitoring data of the water delivery source, calculate the water quality pollution index of the water delivery source, that is:

[0050]

[0051] Among them, NPI is the water quality pollution index of each grid in the water supply source, C′ j represents the j-th water quality monitoring data of each grid in the water supply source, S′ j represents the standard value of the j-th water quality monitoring data of each grid in the upstream area, represents the maximum value of all water quality monitoring data of each grid in the water supply source, represents the average value of all water quality monitoring data of each grid in the water supply source.

[0052] Judge whether the water quality pollution index of the water supply source is greater than the water quality standard threshold. If so, the water quality meets the standard; otherwise, the water quality is abnormal.

[0053] In this embodiment, the water quality pollution index of the water supply source is also the Nemerow pollution index, that is, by calculating the Nemerow pollution index of each grid of the water supply source, it is judged whether the water quality of each grid meets the standard, so as to obtain the grids with unqualified water quality and the areas with unqualified water quality of the water supply source, so as to carry out water quality restoration for the areas with unqualified water quality in the subsequent steps. Among them, the water quality standard threshold is 1.

[0054] Specifically, the specific process of water quality restoration for the water supply source in step S4 is as follows:

[0055] Based on the water quality pollution index of the water supply source, obtain the grids with unqualified water quality in the water supply source, and generate the areas with unqualified water quality of the water supply source;

[0056] For the areas with unqualified water quality of the water supply source, introduce a water quality restoration mechanism to restore the water quality of the areas with unqualified water quality of the water supply source.

[0057] S5. Obtain the service life and design service life of the drinking water pipeline, and combine the drinking water pipeline data to establish a comprehensive aging evaluation model of the drinking water pipeline to judge whether the drinking water pipeline is aging. If so, execute step S6; otherwise, the water quality is safe.

[0058] In this embodiment, the purpose of establishing the comprehensive aging evaluation model of the drinking water pipeline is to judge whether the drinking water pipeline is aging, so as to analyze whether the abnormal water quality of rural drinking water is caused by the aging of the water pipe, so as to accurately obtain the location where the drinking water quality problem occurs.

[0059] Specifically, the specific process of obtaining the service life and design service life of the drinking water pipeline in step S5, combining the drinking water pipeline data, and establishing a comprehensive aging evaluation model of the drinking water pipeline to judge whether the drinking water pipeline is aging is as follows:

[0060] Step1: Calculate the mean values of the water pressure data and water flow rate of the drinking water pipeline respectively, that is:

[0061]

[0062] Among them, is the mean value of the water pressure data of the drinking water pipeline, is the mean value of the water flow rate data of the drinking water pipeline, and P a is the water pressure of the drinking water pipeline at the a-th collection position, and Q b is the water flow rate of the drinking water pipeline at the b-th collection position.

[0063] Step2: Calculate the differences in water pressure at the starting point and the midpoint, the midpoint and the end point, and the starting point and the end point of the drinking water pipeline respectively and find the mean value to obtain the mean value of the pressure change of the drinking water pipeline.

[0064] Step3: Calculate the differences in water flow rate at the starting point and the midpoint, the midpoint and the end point, and the starting point and the end point of the drinking water pipeline respectively and find the mean value to obtain the mean value of the water flow rate change of the drinking water pipeline.

[0065] Step4: Based on the mean value of the water pressure data of the drinking water pipeline and the mean value of the pressure change of the drinking water pipeline, calculate the pressure fluctuation index of the drinking water pipeline, and based on the mean value of the water flow rate of the drinking water pipeline and the mean value of the water flow rate change of the drinking water pipeline, calculate the water flow rate fluctuation index of the drinking water pipeline, that is:

[0066]

[0067] Among them, I P is the pressure fluctuation index, and I Q is the water flow rate fluctuation index. is the mean value of the pressure change of the drinking water pipeline, is the mean value of the water flow rate change of the drinking water pipeline.

[0068] In this embodiment, the pressure fluctuation index reflects the fluctuation degree of the pipeline water pressure, can quantitatively evaluate the water pressure volatility of the drinking water pipeline, and provides an important reference for pipe network design, operation and maintenance, and fault diagnosis; the water flow rate fluctuation index reflects the fluctuation degree of the pipeline water flow rate, and can also quantitatively evaluate the water flow rate volatility of the drinking water pipeline, and provides an important reference for pipe network design, operation and maintenance, and fault diagnosis.

[0069] Step5: Obtain the service life and the designed service life of the drinking water pipeline, and calculate the remaining life index of the drinking water pipeline, that is:

[0070]

[0071] Among them, I T is the remaining life index, T0 is the designed service life of the drinking water pipeline, and T is the service life of the drinking water pipeline.

[0072] In this embodiment, the remaining life index of the drinking water pipeline reflects the remaining life of the drinking water pipeline relative to the designed service life, which can quantitatively evaluate the remaining life of the pipeline and provide an important reference for pipeline network management, maintenance and replacement. The higher the remaining life index value, the longer the remaining life of the pipeline; the lower the remaining life index value, the shorter the remaining life of the pipeline, and timely measures need to be taken.

[0073] Step6: Assign weights to the remaining life index, pressure fluctuation index, and water flow fluctuation index respectively, and establish a comprehensive aging evaluation model for the drinking water pipeline to calculate the comprehensive aging evaluation value of the drinking water pipeline, that is:

[0074] CAI = ω1I T +ω2I P +ω3I Q

[0075] ω1 + ω2 + ω3 = 1

[0076] Where, CAI is the comprehensive aging evaluation value, and ω1, ω2, and ω3 are the weights of the remaining life index, pressure fluctuation index, and water flow fluctuation index respectively.

[0077] In this embodiment, by combining historical pipeline collection data and expert experience, the weights of the remaining life index, pressure fluctuation index, and water flow fluctuation index are assigned as 0.5, 0.3, and 0.2 respectively, that is, the remaining life is the most important, the pressure fluctuation is the second most important, and the water flow fluctuation is relatively important, so as to establish a comprehensive aging evaluation model for the drinking water pipeline to evaluate the comprehensive aging status of the drinking water pipeline.

[0078] Step7: Judge whether the comprehensive aging evaluation value of the drinking water pipeline is greater than the aging threshold of the drinking water pipeline. If so, the drinking water pipeline is aging; otherwise, the drinking water pipeline is normal.

[0079] In this embodiment, the aging threshold of the drinking water pipeline is 0.6. When the comprehensive aging evaluation value of the drinking water pipeline is greater than 0.6, it indicates that the drinking water pipeline is severely aging and needs to be replaced in time.

[0080] S6. Obtain the water quality monitoring data at the outlet of the drinking water pipeline, and judge whether the water quality monitoring data at the outlet of the drinking water pipeline is abnormal. If so, replace the drinking water pipeline; otherwise, the water quality is safe.

[0081] In this embodiment, after judging that the drinking water pipeline is aging, it is also necessary to collect the water quality monitoring data at the outlet of the drinking water pipeline again to judge whether these water quality monitoring data are abnormal. If they are abnormal, it means that the aging of the water pipe will affect the water quality. Therefore, the water quality can be ensured by replacing the drinking water pipeline.

[0082] In summary, a method for monitoring, evaluating, warning of the quantity and quality of rural drinking water safety proposed by the present invention monitors and repairs the water quality of the water supply source and the upstream area of the water supply source, and combines the drinking water pipeline data at the same time, so as to quickly identify drinking water safety problems, so as to repair the water quality in a timely and effective manner, greatly improving the safety of rural drinking water; through multi-dimensional data collection of the water supply source, the upstream area of the water supply source and the drinking water pipeline, the all-round monitoring of the quantity and quality of rural drinking water safety is realized, avoiding monitoring blind spots; with the help of efficient data analysis of the real-time collected multi-dimensional data, the location where drinking water safety problems occur can be found in the first time and timely warned and repaired, improving the speed of water quality safety repair, effectively guaranteeing the drinking water safety of rural residents; compared with the traditional method of directly replacing the drinking water pipeline on a large scale or frequent manual detection, the present invention reduces unnecessary cost investment and improves resource utilization rate by accurately positioning the location of water quality safety problems.
