BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 This is a flow chart of a rural drinking water safety quantity and quality monitoring and early warning method proposed by the present invention. DETAILED DESCRIPTION

[0018] The specific embodiments of the present invention are described below to facilitate understanding of the present invention by those skilled in the art. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the appended claims, these changes are obvious, and all inventions and creations utilizing the concepts of the present invention are protected.

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

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

[0021] Specifically, step S1 includes: obtaining the rural drinking water delivery source and the upstream area of ​​the delivery source, uniformly gridding the delivery source and the upstream area of ​​the delivery source respectively, and collecting water quality monitoring data of the delivery source and the upstream area by arranging a water quality sensor group in the center of each grid.

[0022] In this embodiment, the rural drinking water delivery source is the area that directly provides water to rural users; the upstream area of ​​the delivery source is the upstream portion of the water flow from the delivery source. Because the water quality upstream of the delivery source can affect the water quality of the delivery source, the water quality of the rural drinking water delivery source and the upstream area of ​​the delivery source are monitored separately to facilitate subsequent rural drinking water safety quality and quantity monitoring and early warning. In addition, the purpose of uniformly gridding the delivery source and the upstream area of ​​the delivery source is to ensure that each grid covers a certain spatial range to obtain accurate water quality monitoring data, while facilitating the subsequent acquisition of accurate water quality substandard areas. These substandard areas can be targeted for processing to reduce labor costs and computational complexity. The water quality sensor group includes sensors for monitoring pH, temperature, dissolved oxygen, conductivity, and turbidity.

[0023] S2. Obtain drinking water pipeline data for rural drinking water.

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

[0025] In this embodiment, the purpose of collecting drinking water pipe data for rural drinking water is to determine whether the drinking water pipe is aged in subsequent steps, and thus determine whether the abnormality in the water quality monitoring data of rural drinking water is related to the aging of the water pipe.

[0026] S3. Determine 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 determining whether the water quality monitoring data in the upstream area is abnormal is: since the water quality conditions upstream of the transmission source will affect the water quality of the transmission source, it is first determined whether the upstream water quality is abnormal. If the upstream is abnormal, the early warning mechanism is triggered to repair the water quality in the upstream area.

[0028] Specifically, the specific process of determining 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, the water pollution index of the upstream area is calculated, namely:

[0030]

[0031] Among them, NPI is the water pollution index of each grid in the upstream area, C i represents the 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 of 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 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 for the upstream region is the Nemerow pollution index. Specifically, by calculating the Nemerow pollution index for each grid in the upstream region, it is determined whether the water quality of each grid meets the standard. This allows for identifying grids with substandard water quality and identifying substandard water quality areas, allowing for subsequent water quality remediation in these substandard areas. The water quality standard threshold is 1.

[0034] Specifically, the specific process of repairing the water quality in the upstream area in step S3 is:

[0035] Based on the water pollution index of the upstream area, the grids with substandard water quality in the upstream area are obtained, and the substandard water quality areas in the upstream area are generated; for the substandard water quality areas in the upstream area, a water quality repair mechanism is introduced to repair the water quality in the substandard water quality areas in the upstream area.

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

[0037] If the dissolved oxygen in the area where the water quality does not meet the standard is lower than the standard value of dissolved oxygen in the water quality, aeration equipment will be used to inject oxygen into the area where the water quality does not meet the standard.

[0038] In this embodiment, aeration equipment is used to inject oxygen into the water quality area that does not meet the standard, which is aeration remediation. This aeration remediation is performed on the area with insufficient dissolved oxygen, thereby increasing the dissolved oxygen concentration and promoting the self-purification ability of the water body. The oxygen injection amount is: ΔDO = K(C s -C0), ΔDO is the dissolved oxygen increase or injection amount, K is the aeration efficiency coefficient, and this coefficient is related to the type of aeration equipment and water conditions, C s is the saturated dissolved oxygen concentration, which is related to temperature, and C0 is the current dissolved oxygen solubility; therefore, based on the oxygen injection amount, the final target dissolved oxygen concentration C target For: C target =C0+ΔDO to ensure C target ≥5mg / L.

[0039] If the pH value of the water quality area that does not meet the standard is acidic, alkaline substances will be added to the water quality area to neutralize the acidity. If the pH value of the water quality area that does not meet the standard is alkaline, acidic substances will be added to the water quality area to neutralize the alkalinity.

[0040] In this embodiment, the pH value of the water is acidic, i.e., pH < 6.5; the pH value of the water is alkaline, i.e., pH > 8.5. Therefore, if the pH value is too low, alkaline substances such as limestone or 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 are highly safe) can be added to neutralize the alkalinity. The safety of the drinking water should be considered when selecting the acidic or alkaline substance to be added, as well as the dosage of the substance to be added.

[0041] If the temperature in the area where water quality does not meet the standards is too low, solar energy equipment will be installed at the boundary of the area to increase heat input, or the frequency of water release from the reservoir will be reduced to reduce cold water input; if the temperature in the area where water quality does not meet the standards is too high, trees will be planted at the boundary of the area to reduce the temperature by increasing shade on the water body.

[0042] In this example, if the water temperature is too high, it may be caused by industrial cooling water discharge or global warming; if the water temperature is too low, it may be caused by cold water discharge or cold weather. Therefore, the water temperature is corrected. If the temperature is too high, solar panels can be installed on both sides of the boundary of the area where the water temperature does not meet the standard to increase the water heat input. Alternatively, the reservoir water release strategy can be adjusted to reduce the frequency of reservoir water release to reduce the cold water input. If the temperature is too high, trees can be planted on the boundary of the area where the water quality does not meet the standard to provide shade and thus reduce the temperature.

[0043] If the conductivity of the area where the water quality does not meet the standards is too high, the high-salinity water body will be diluted by introducing clean water.

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

[0045] If the turbidity in the area where the water quality does not meet the standards is too high, flocculants are added to settle the suspended particles.

[0046] In this embodiment, the turbidity of the water body is usually caused by excessive suspended particles such as mud, sand, and algae. Generally, the suspended particles can be precipitated by adding flocculants or removed by using sand filtration or membrane filtration.

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

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

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

[0050]

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

[0052] Determine whether the water pollution index of the transmission 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 transport source is also the Nemerow pollution index. That is, by calculating the Nemerow pollution index for each grid in the transport source, it is determined whether the water quality of each grid meets the standard. This allows the identification of grids with substandard water quality, and the identification of substandard water quality areas in the transport source, allowing subsequent steps to repair the water quality in these substandard areas. The water quality standard threshold is 1.

[0054] Specifically, the specific process of repairing the water quality of the delivery source in step S4 is:

[0055] Based on the water pollution index of the transmission source, the grids with substandard water quality in the transmission source are obtained, and the substandard water quality areas of the transmission source are generated;

[0056] For areas where the water quality of the transmission source does not meet the standards, a water quality restoration mechanism is introduced to repair the water quality in areas where the water quality of the transmission source does not meet the standards.

[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 assessment model for the drinking water pipeline to determine whether the drinking water pipeline is aged. If so, execute step S6; otherwise, the water quality is safe.

[0058] In this embodiment, the purpose of establishing a comprehensive aging assessment model for drinking water pipes is to determine whether the drinking water pipes are aging, so as to analyze whether the abnormal water quality of rural drinking water is caused by aging of the pipes, and thus accurately determine the location of the drinking water quality problem.

[0059] Specifically, in step S5, the service life and design service life of the drinking water pipeline are obtained, and combined with the drinking water pipeline data, a comprehensive aging assessment model for the drinking water pipeline is established. The specific process of determining whether the drinking water pipeline is aged is as follows:

[0060] Step 1: Calculate the mean of the water pressure data and water flow rate of the drinking water pipe respectively, namely:

[0061]

[0062] in, is the mean of the water pressure data of the drinking water pipeline, is the mean of the water flow data of the drinking water pipeline, P a is the water pressure of the drinking water pipe at the ath collection location, Q b is the water flow rate of the drinking water pipe at the bth collection location.

[0063] Step 2: Calculate the difference in water pressure between the starting point and midpoint, midpoint and end point, and starting point and end point of the drinking water pipe and calculate the average value to obtain the average pressure change of the drinking water pipe.

[0064] Step 3: Calculate the difference in water flow between the starting point and midpoint, midpoint and end point, and starting point and end point of the drinking water pipe and calculate the average to obtain the average change in water flow in the drinking water pipe.

[0065] Step 4: Based on the mean of the water pressure data of the drinking water pipe and the mean of the pressure change of the drinking water pipe, calculate the pressure fluctuation index of the drinking water pipe. Based on the mean of the water flow of the drinking water pipe and the mean of the water flow change of the drinking water pipe, calculate the water flow fluctuation index of the drinking water pipe, that is:

[0066]

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

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

[0069] Step 5: Obtain the service life and design service life of the drinking water pipeline and calculate the remaining life index of the drinking water pipeline, namely:

[0070]

[0071] Among them, I T It is the remaining life indicator, T0 is the design 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. It 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] Step 6: Assign weights to the remaining life index, pressure fluctuation index, and water flow fluctuation index respectively, establish a comprehensive aging assessment model for drinking water pipelines, and calculate the comprehensive aging assessment value of drinking water pipelines, namely:

[0074] CAI=ω1I T +ω2I P +ω3I Q

[0075] ω1+ω2+ω3=1

[0076] Among them, CAI is the comprehensive aging assessment value, 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 to 0.5, 0.3, and 0.2, respectively. That is, the remaining life is the most important, the pressure fluctuation is second important, and the water flow fluctuation is more important. In this way, a comprehensive aging assessment model for drinking water pipelines is established to evaluate the comprehensive aging status of drinking water pipelines.

[0078] Step 7: Determine whether the comprehensive aging assessment value of the drinking water pipeline is greater than the drinking water pipeline aging threshold. If so, the drinking water pipeline is aged; otherwise, the drinking water pipeline is normal.

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

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

[0081] In this embodiment, after determining that the drinking water pipe is aging, it is necessary to collect water quality monitoring data from the drinking water pipe outlet again to determine whether these water quality monitoring data are abnormal. If abnormal, it means that the aging of the water pipe will affect the water quality. Therefore, the drinking water pipe can be updated to ensure water quality safety.

[0082] In summary, the method for monitoring and early warning of the quantity and quality of rural drinking water safety proposed in the present invention monitors and repairs the water quality of the delivery source and the upstream area of ​​the delivery source, and combines the drinking water pipeline data to quickly identify drinking water safety problems, so as to timely and effectively repair the water quality, thereby greatly improving the safety of rural drinking water; by collecting multi-dimensional data of the delivery source, the upstream area of ​​the delivery source and the drinking water pipeline, all-round monitoring of the quantity and quality of rural drinking water safety is achieved, avoiding monitoring blind spots; with the help of efficient data analysis based on the multi-dimensional data collected in real time, the location of drinking water safety problems can be discovered in the first time and early warnings and repairs can be issued in time, thereby improving the speed of water quality safety repair and effectively ensuring the drinking water safety of rural residents; compared with the traditional large-scale and direct replacement of drinking water pipelines or frequent manual inspections, the present invention reduces unnecessary cost investment and improves resource utilization by accurately locating the location of water quality safety problems.
