Summary of the invention

[0006] Through this solution, by obtaining tap water monitoring information, collecting real-time material data, real-time free chlorine data and real-time water body data, it provides the necessary basis for subsequent regulation. Based on these data, the chlorine reaction information is analyzed, the disinfection effect and reaction rate of chlorine in water are evaluated, and the interaction between chlorine and pollutants in water is judged. According to the chlorine reaction information, real-time material data and real-time free chlorine data, the chlorine addition strategy is accurately determined, and the chlorine addition amount and timing are adjusted to ensure that the water quality achieves the best disinfection effect. The optimized addition strategy is sent to the tap water purification management system to ensure the accurate execution of the addition operation, reduce the waste of chlorine, and ensure the safety of water quality. Through this process, the chlorine addition amount can be dynamically adjusted to improve the water treatment efficiency, while reducing the risk of excessive addition and insufficient disinfection.

[0008] Through this solution, the water quality can be fully understood by obtaining real-time water data, real-time free chlorine data, real-time material data and environmental monitoring data. Determine whether the material type reacts with free chlorine. If a reaction occurs, further determine the ultraviolet intensity based on environmental monitoring data, taking into account the effect of ultraviolet light on chlorine reaction. Based on multiple parameters, a formula is used to calculate the degree of conversion between free chlorine and combined chlorine. Each variable involved in the formula has a direct impact on the degree of conversion. This degree of conversion reflects the dynamic balance between free chlorine and combined chlorine, which will help to formulate a more reasonable and scientific chlorine addition strategy and improve the accuracy and efficiency of water purification.

[0009] Optionally, determining chlorine reaction information according to the real-time substance data, the real-time free chlorine data and the real-time water body data includes: Determine the chlorine demand of the substance in the water body for free chlorine based on the type of the substance and the concentration of the substance; Determining the reaction concentration of combined chlorine in the water body according to the degree of conversion and the free chlorine concentration; Determining the influence of combined chlorine on the reaction of free chlorine according to the reaction concentration, the chlorine demand and the water flow rate; The impact levels are incorporated into the chlorine response information.

[0010] Through this solution, the chlorine demand of various substances in the water body for free chlorine can be calculated based on real-time material data and material concentration, helping to predict the consumption demand of free chlorine in the water body. By combining the degree of conversion and the free chlorine concentration, the reaction concentration of combined chlorine in the water body can be accurately calculated, reflecting the chemical reaction state of chlorine and other substances. Combined with the comprehensive analysis of reaction concentration, chlorine demand and water flow rate, the degree of influence of combined chlorine in the water body on the free chlorine reaction is evaluated to ensure that the dynamic changes of the chlorine reaction process are accurately captured. Combining all data, the degree of influence is incorporated into the chlorine reaction information to provide a scientific basis for real-time adjustment of water treatment strategies and improve the accuracy and efficiency of water quality control. Through the refined analysis of the chlorine reaction process in the water body, the use of chlorine can be optimized to ensure stable and safe water quality.

[0011] Optionally, the real-time substance data includes the number and type of microorganisms, and the determining of chlorine reaction information according to the real-time substance data, the real-time free chlorine data and the real-time water body data includes: Determining the intensity of free chlorine consumption by microorganisms in the water body according to the type of microorganisms; The consumption volume of free chlorine by microorganisms per unit time is determined according to the consumption intensity, the degree of conversion, the number of microorganisms, the water temperature, the pH value of the water and the water flow rate, and is calculated according to the following formula: ; in, represents the consumed volume, represents the consumption intensity, represents the degree of conversion, represents the free chlorine concentration, represents the number of microorganisms, represents the water body temperature, represents the pH value of the water body, Indicates the preset temperature influence coefficient, Indicates the preset acid-base adjustment coefficient; The consumed volume is included in the chlorine reaction information.

[0012] Through this solution, the consumption intensity of free chlorine by different types of microorganisms in the water body is determined according to the type of microorganism, providing a basis for the subsequent reaction model. By combining the consumption intensity, degree of conversion, number of microorganisms, temperature, pH value and water flow rate, the volume of free chlorine consumed by microorganisms is calculated using a formula. The formula ensures the accuracy of the formula under different conditions by adjusting multiple environmental factors, especially by adjusting the water temperature and pH value to reflect the dynamic changes of the water body in actual operation. Incorporating the consumption volume into the chlorine reaction information helps to monitor the chlorine consumption in real time and optimize the amount of chlorine added during the water treatment process to ensure that the water quality is stable and meets the standards. At the same time, it effectively improves the accuracy and control efficiency of the chlorine reaction to ensure the safety and treatment effect of the water body.

[0013] Optionally, the real-time material data includes suspended particle concentration, and determining a chlorine dosing strategy in tap water according to the chlorine reaction information, the real-time material data and the real-time free chlorine data includes: Determining the reaction time of the substance and the free chlorine according to the concentration of the substance, the concentration of free chlorine and the flow rate of the water body; Determining the dosage of chlorine according to the reaction time, the free chlorine concentration, the consumed volume and the degree of conversion; Determining the duration of chlorine addition according to the suspended particle concentration, the substance concentration, the reaction time and the water temperature; The dosage and the dosage duration are incorporated into the dosage strategy.

[0014] Through this solution, the reaction time between the substance and free chlorine is accurately calculated by combining the substance concentration, free chlorine concentration and water flow rate, thereby ensuring the full reaction of chlorine. The amount of chlorine added is calculated based on the reaction time, free chlorine concentration, consumption volume and degree of conversion to avoid excessive or insufficient chlorine addition, ensuring the consumption of chlorine in the water body and the stability of water quality. By comprehensively considering factors such as suspended particle concentration, substance concentration, reaction time and water body temperature, the duration of chlorine addition is determined to further optimize the efficiency of chlorine use. Incorporating the dosage and duration of addition into the addition strategy provides a scientific basis for real-time adjustment of chlorine addition, ensuring that the use of chlorine in the water treatment process is both efficient and economical. Through fine parameter adjustment, the flexibility and accuracy of the water treatment process are enhanced, the amount of chlorine added is effectively controlled, and the quality of tap water treatment is ensured to be up to standard and safe.

[0015] Optionally, the tap water monitoring information includes water volume, the real-time substance data includes a first substance concentration, and determining the amount of chlorine to be added according to the reaction time, the free chlorine concentration, the consumed volume and the conversion degree includes: Obtaining a qualified range of substance concentration, matching the qualified range of substance concentration with the first substance concentration, and if the first substance concentration is not within the qualified range of substance concentration, determining that the harmful substances in the tap water are not completely eliminated; Determining a substance concentration difference according to the qualified substance concentration range and the first substance concentration; The amount of chlorine added is determined based on the substance concentration difference, the reaction time, the water volume, the free chlorine concentration, the consumed volume and the degree of conversion, and is calculated according to the following formula: ; in, represents the dosage, represents the concentration difference of the substance, represents the volume of the water body, represents the reaction time, represents the free chlorine concentration, represents the degree of conversion, Indicates the consumed volume.

[0016] Through this solution, the qualified range of substance concentration is obtained and matched with the first substance concentration. If the first substance concentration is not within the qualified range, it can be determined that the harmful substances in the water have not been completely eliminated. According to the difference between the qualified range of substance concentration and the first substance concentration, the difference in substance concentration is determined to provide a basis for the subsequent calculation of the amount of chlorine added. Combining the reaction time, water volume, free chlorine concentration, consumption volume and degree of conversion, the precise amount of chlorine added is calculated using a formula. In the formula, factors such as the difference in substance concentration, reaction time, and water volume work together to ensure that the amount of chlorine added can effectively eliminate harmful substances in the water without causing excessive chlorine pollution. Through this series of steps, a quantitative and controllable solution is provided for the addition of chlorine in tap water, ensuring the accuracy of the water treatment process and the safety of water quality.

[0017] Optionally, before determining the dosage of chlorine according to the reaction time, the free chlorine concentration, the consumed volume and the degree of conversion, the method further comprises: If the concentration of the first substance is within the qualified range of the substance concentration, then obtaining the qualified range of free chlorine concentration, matching the free chlorine concentration with the qualified range of concentration, and if the free chlorine concentration is not within the qualified range of concentration, determining that the free chlorine concentration in the water body exceeds the standard; According to the free chlorine concentration and the qualified concentration range, determining the excess free chlorine concentration value; Determining the excess free chlorine volume according to the water volume and the concentration exceeding the standard value; Determining the residence time of the free chlorine volume in the water volume according to the free chlorine volume, the degree of conversion and the first substance concentration; The dosing frequency of chlorine is determined according to the residence time.

[0018] Through this solution, if the concentration of the first substance is within the qualified concentration range, the qualified concentration range of free chlorine is obtained and matched. If the free chlorine concentration exceeds this range, it is determined that the free chlorine concentration in the water exceeds the standard. According to the difference between the free chlorine concentration and the qualified concentration range, the value of the free chlorine concentration exceeding the standard is calculated. Combining the volume of the water body and the value of the concentration exceeding the standard, the excess free chlorine volume is determined to provide data support for the subsequent adjustment of chlorine. According to the excess free chlorine volume, the degree of conversion and the concentration of the first substance, the residence time of free chlorine in the water body is calculated. Combining the residence time with the reaction time, the frequency of chlorine addition is determined to ensure the stability of the chlorine concentration in the water and avoid excessive addition. Through these fine steps, while effectively adjusting the amount and frequency of chlorine use, it is ensured that the chlorine concentration in the water quality treatment process meets the standard and does not produce side effects, thereby achieving the best water quality control effect.

[0019] Optionally, determining the duration of adding chlorine according to the suspended particle concentration, the substance concentration, the reaction time and the water temperature includes: The duration of chlorine addition is determined based on the suspended particle concentration, the free chlorine concentration, the substance concentration, the water volume, the reaction time and the water temperature, and is calculated according to the following formula: ; in, Indicates the duration of the addition, represents the concentration of the substance, represents the volume of the water body, Indicates the preset particle influence coefficient, represents the suspended particle concentration, represents the reaction time, represents the free chlorine concentration, Indicates the preset temperature influence coefficient, Represents the temperature of the water body.

[0020] Through this solution, these factors are introduced into the formula for calculation based on the suspended particle concentration, free chlorine concentration, substance concentration, water volume, reaction time and water temperature. The substance concentration, suspended particle concentration and free chlorine concentration in the formula work together to ensure that the amount and duration of chlorine addition can effectively cope with the situation of different substances in the water. Specifically, the preset particle influence coefficient combined with the suspended particle concentration can take into account the influence of suspended particles on the chlorine reaction, and then adjust the addition time. At the same time, the introduction of the temperature influence coefficient and the water temperature effectively considers the interaction between the reaction time and the water temperature. Through this calculation, the chlorine addition time is accurately determined, so that the reaction between chlorine and harmful substances in the water is completed at the best time, avoiding excessive or insufficient chlorine addition, and ensuring the stability and safety of the water quality treatment effect.

[0021] Optionally, after determining the chlorine addition strategy for tap water according to the chlorine reaction information, the real-time substance data and the real-time free chlorine data, the method further includes: Determining the purified free chlorine concentration in the purified tap water according to the real-time free chlorine data; Determining the concentration of the purified substance in the purified tap water according to the real-time substance data; Determining the concentration of purified suspended particles in the purified tap water according to the real-time water body data; The degree of purification of the tap water is determined according to the concentration of the purified substance, the concentration of purified free chlorine, the reaction time and the concentration of purified suspended particles.

[0022] Through this solution, the concentration of purified free chlorine in the purified tap water is calculated through real-time free chlorine data, so as to evaluate the consumption of free chlorine and its effectiveness. According to the real-time material data, the concentration of purified substances in the purified tap water is calculated to ensure that the residual substances in the water meet the standards. The degree of purification of tap water is comprehensively evaluated by combining factors such as the concentration of purified substances, the concentration of purified free chlorine, the reaction time and the concentration of suspended particles. This step comprehensively reflects the purification effect of the water body, taking into account the process of the reaction between free chlorine and substances, and the influence of suspended particles on the reaction, thereby providing a scientific basis for further optimizing the dosage of chlorine and purification time. Through this series of operations, not only can the use of chlorine be accurately controlled, but also the quality of tap water can be ensured to meet the standards, excessive or insufficient purification can be avoided, and ultimately the optimal water quality management can be achieved.

Combined with the chlorine reaction information and real-time data, a chlorine addition strategy is formulated, and the strategy is transmitted to the tap water purification management system to achieve accurate and efficient water quality control and optimization.

[0033] For specific implementation methods, please refer to the following embodiments.

[0034] Figure 2 This is a flow chart of a tap water purification method provided in an embodiment of the present application. The method of this embodiment can be applied to the server in the above scenario. Figure 2 As shown, the method includes: S201. Obtain tap water monitoring information, and determine real-time substance data, real-time free chlorine data, and real-time water body data based on the tap water monitoring information.

[0035] The tap water monitoring information may be information obtained by monitoring the tap water being purified. The tap water monitoring information may include real-time material data, real-time free data, and real-time water body data.

[0036] The real-time substance data may be data corresponding to characteristics of substances contained in the tap water being purified. The real-time substance data may include substance concentrations.

[0037] The real-time free chlorine data may be data corresponding to characteristics of free chlorine contained in the tap water being purified. The real-time free chlorine data may include free chlorine concentration.

[0038] The real-time water body data may be basic information corresponding to the tap water being purified. The real-time water body data may include water body temperature.

[0039] Specifically, material monitoring data is obtained from the material monitoring device, and water body monitoring data is obtained from the water body monitoring device. The material monitoring data and water body monitoring data obtained in the above steps are integrated to obtain tap water monitoring information. Material concentration, water body temperature and free chlorine concentration are obtained from the tap water monitoring information, and the material concentration is included in the real-time material data, and the free chlorine concentration is included in the real-time free chlorine data. The water body temperature is included in the real-time water body data.

[0040] S202. Determine chlorine reaction information based on real-time substance data, real-time free chlorine data, and real-time water body data.

[0041] The chlorine reaction information may be information about chlorine-containing substances in tap water after free chlorine reacts with substances in tap water. The chlorine reaction information may include combined chlorine concentration.

[0042] Specifically, a mathematical analysis method is used to analyze the substance concentration, free chlorine concentration and water temperature obtained in the above steps, to determine the combined chlorine concentration generated by the reaction between free chlorine in tap water and substances in the water body, and to include the combined chlorine concentration in the chlorine reaction information.

[0043] S203. Determine the chlorine dosing strategy in tap water according to the chlorine reaction information, real-time substance data and real-time free chlorine data, and send the dosing strategy to the tap water purification management system.

[0044] The dosing strategy may be a strategy determined when chlorine is added to the tap water in order to effectively remove substances in the tap water without affecting the water purification quality.

[0045] Specifically, a mathematical analysis method is used to analyze the combined chlorine concentration, substance concentration and free chlorine concentration obtained in the above steps to determine the dosage of chlorine in the tap water, and the dosage of chlorine is included in the dosage strategy. The dosage strategy is sent to the tap water purification management system, and the tap water purification management system adds chlorine according to the dosage strategy to ensure the treatment effect of tap water purification.

[0046] Through this solution, by obtaining tap water monitoring information, collecting real-time material data, real-time free chlorine data and real-time water body data, it provides the necessary basis for subsequent regulation. Based on these data, the chlorine reaction information is analyzed, the disinfection effect and reaction rate of chlorine in water are evaluated, and the interaction between chlorine and pollutants in water is judged. According to the chlorine reaction information, real-time material data and real-time free chlorine data, the chlorine addition strategy is accurately determined, and the chlorine addition amount and timing are adjusted to ensure that the water quality achieves the best disinfection effect. The optimized addition strategy is sent to the tap water purification management system to ensure the accurate execution of the addition operation, reduce the waste of chlorine, and ensure the safety of water quality. Through this process, the chlorine addition amount can be dynamically adjusted to improve the water treatment efficiency, while reducing the risk of excessive addition and insufficient disinfection.

[0047] In some embodiments, it is determined whether the substance type reacts with free chlorine. If a reaction occurs, the ultraviolet intensity is determined based on environmental monitoring data. The degree of conversion between free chlorine and combined chlorine is determined by calculation according to formula (1) based on water temperature, free chlorine concentration, substance concentration, water pH value, water flow rate and ultraviolet intensity. The degree of conversion is incorporated into the chlorine reaction information: (1) in, Indicates the degree of conversion. Indicates the free chlorine concentration, represents the concentration of a substance, Indicates the water temperature, Indicates the pH value of water. Indicates the water flow velocity, Indicates the intensity of ultraviolet light.

[0048] Real-time water data includes water temperature, water pH value and water flow rate. Real-time free chlorine data includes free chlorine concentration. Real-time substance data includes substance concentration and substance type. Tap water monitoring information includes environmental monitoring data.

[0049] The free chlorine concentration may be a concentration corresponding to the free chlorine contained in the tap water before chlorine is added to the tap water.

[0050] The environmental monitoring data may be data obtained by monitoring the meteorological environment at the location of the water plant, and may be obtained by water body monitoring equipment, so the environmental monitoring data may be included in the tap water monitoring information.

[0051] The degree of conversion may be a numerical value corresponding to the conversion ratio of free chlorine and combined chlorine in tap water when they are converted into each other.

[0052] Specifically, the pH value of water will directly affect the chemical form of free chlorine. Under acidic conditions, free chlorine mainly exists in the form of HOCl, while under alkaline conditions, it mainly exists in the form of OCl. When the pH value of water changes, HOCl and OCl There is a conversion between free chlorine and combined chlorine. When there is ammonia or other nitrogen sources in the water, free chlorine (especially HOCl) reacts with ammonia to form chloramines. This process is the process of converting free chlorine into combined chlorine. Under certain conditions, especially under high temperature or ultraviolet radiation, combined chlorine can decompose and release free chlorine. This process can reverse the formation of combined chlorine. Therefore, the conversion between free chlorine and combined chlorine is a dynamic equilibrium process, which is affected by factors such as the pH value of the water body, the temperature of the water body, and the concentration of substances in the water body (such as ammonia nitrogen concentration).

[0053] Therefore, the pH value of the water body and the flow rate of the water body are extracted from the real-time water body data, and the type of substance is extracted from the real-time material data. All possible types of substances and the judgment results of whether they react with free chlorine are obtained from the material research website, and all possible types of substances and the judgment results of whether they react with free chlorine are integrated to obtain a preset material reaction set. The substance type obtained in the above steps is matched with the preset material reaction set. If the judgment result corresponding to the substance type shows that the substance type obtained in the above steps will react with free chlorine, the environmental monitoring data is extracted from the tap water monitoring information, and the ultraviolet intensity is extracted from the environmental monitoring data. Because the water body monitoring equipment is set in and around the water body, the data corresponding to the meteorological environment of the location of the water plant can be obtained from the monitoring equipment set around the water body, and this data can be included in the tap water monitoring information. Therefore, the environmental monitoring data can be extracted from the tap water monitoring information. The water temperature, free chlorine concentration, substance concentration, water pH, water flow rate and ultraviolet intensity obtained in the above steps are analyzed using mathematical analysis methods. The degree of conversion between free chlorine and combined chlorine is determined according to formula (1), and the degree of conversion is incorporated into the chlorine reaction information.

[0054] In formula (1), Reflects the free chlorine concentration Concentration of substances in water that may react with free chlorine The mutual relationship between them. The effect of water pH on the conversion process is described. When the water pH is 7, the ratio of free chlorine and hypochlorous acid (one of the forms of free chlorine) is balanced, but this balance point is not fixed. In the actual environment, the water pH of 7 is not necessarily an ideal dividing point, especially in some special water bodies, the reaction rate and the conversion of free chlorine will be affected by slight changes in acidity and alkalinity. In addition, in most natural water bodies and treated water, the pH value of the water body is not always strictly 7, but is usually slightly acidic or alkaline. For example, the pH value of tap water is usually between 7.2 and 8.2. Selecting a water pH of 7.5 as a benchmark is closer to the equilibrium point under common environmental conditions. From the perspective of chemical kinetics, the conversion process of free chlorine and combined chlorine is more stable or more reactive when the water pH is 7.5. Therefore, the water pH of 7.5 as a benchmark value can more accurately reflect the actual conversion of chlorine reaction. In summary, when the water pH is close to 7.5, the conversion effect is the strongest, and when it deviates from 7.5, the degree of conversion will slow down. Overall, This makes the reaction more likely to occur when the pH value of the water is close to neutral, thereby enhancing the driving effect of the conversion. It represents the product of a series of factors that promote the conversion of free chlorine, which together promote the process of conversion of free chlorine to combined chlorine.

[0055] Denominator: It expresses the "constraint" or "limiting factor" that affects the conversion of free chlorine. Under the condition of high concentration of free chlorine, the degree of conversion will be inhibited to a certain extent. Therefore, the free chlorine concentration Appears in the denominator. Represents the effect of water temperature on conversion. Used to represent the acceleration effect when the temperature is high (assuming 10°C as the base temperature). However, high water temperature can also make some reaction processes unstable, so this limiting effect is added to the denominator. When the water flows faster, the contact time of substances in the water is shorter and the possibility of reaction is reduced; higher ultraviolet intensity may help the decomposition of free chlorine. Therefore, The number 1 mathematically ensures that the minimum value of the denominator is greater than zero, avoiding the situation where the divisor is zero. It also means that when all other factors are invalid, there will still be a certain baseline inhibition effect.

[0056] Through this solution, the water quality can be fully understood by obtaining real-time water data, real-time free chlorine data, real-time material data and environmental monitoring data. Determine whether the material type reacts with free chlorine. If a reaction occurs, further determine the ultraviolet intensity based on environmental monitoring data, taking into account the effect of ultraviolet light on chlorine reaction. Based on multiple parameters, the degree of conversion between free chlorine and combined chlorine is calculated using a formula, and each variable involved in the formula has a direct impact on the degree of conversion. The degree of conversion reflects the dynamic balance between free chlorine and combined chlorine, which will help to formulate a more reasonable and scientific chlorine addition strategy and improve the accuracy and efficiency of water purification.

[0057] In some embodiments, the chlorine demand of substances in water for free chlorine is determined based on the substance type and substance concentration; the reaction concentration of combined chlorine in water is determined based on the degree of conversion and the free chlorine concentration; the degree of influence of combined chlorine on the reaction of free chlorine is determined based on the reaction concentration, chlorine demand and water flow rate; and the degree of influence is incorporated into the chlorine reaction information.

[0058] The chlorine demand can be the volume of free chlorine required to eliminate substances in tap water. The reaction concentration can be the concentration of combined chlorine generated by the reaction of free chlorine in tap water with substances in tap water.

[0059] The degree of influence may be a numerical value corresponding to the effect of combined chlorine in tap water on the process of reaction between free chlorine and substances other than combined chlorine.

[0060] Specifically, when the above steps determine that the substance type will react with the free chlorine in the tap water, the amount of free chlorine required to completely remove the current substance type in the tap water is obtained from the substance research website, and the amount of free chlorine required to completely remove the current substance type in the tap water is determined as the chlorine demand. The degree of conversion is multiplied by the free chlorine concentration to obtain the reaction concentration of combined chlorine in the water body. Mathematical analysis methods are used to analyze the reaction concentration, chlorine demand and water flow rate to determine the degree of influence of combined chlorine on the reaction of free chlorine. The degree of influence is included in the chlorine reaction information.

[0061] Through this solution, the chlorine demand of various substances in the water body for free chlorine can be calculated based on real-time material data and material concentration, helping to predict the consumption demand of free chlorine in the water body. By combining the degree of conversion and the free chlorine concentration, the reaction concentration of combined chlorine in the water body can be accurately calculated, reflecting the chemical reaction state of chlorine and other substances. Combined with the comprehensive analysis of reaction concentration, chlorine demand and water flow rate, the degree of influence of combined chlorine in the water body on the free chlorine reaction is evaluated to ensure that the dynamic changes of the chlorine reaction process are accurately captured. Combining all data, the degree of influence is incorporated into the chlorine reaction information to provide a scientific basis for real-time adjustment of water treatment strategies and improve the accuracy and efficiency of water quality control. Through the refined analysis of the chlorine reaction process in the water body, the use of chlorine can be optimized to ensure stable and safe water quality.

[0062] In some embodiments, the intensity of free chlorine consumption by microorganisms in the water is determined based on the type of microorganisms; the volume of free chlorine consumed by the microorganisms per unit time is determined based on the consumption intensity, the degree of conversion, the number of microorganisms, the temperature of the water body, the pH value of the water body and the flow rate of the water body according to formula (2); and the consumption volume is included in the chlorine reaction information: (2) in, Indicates the consumed volume, Indicates the consumption intensity, Indicates the degree of conversion. Indicates the free chlorine concentration, Represents the number of microorganisms, Indicates the water temperature, Indicates the pH value of water. Indicates the preset temperature influence coefficient, Indicates the preset acid-base adjustment factor.

[0063] Real-time material data includes microbial counts and microbial types.

[0064] The microorganism type may be a type corresponding to microorganisms in tap water that are capable of consuming free chlorine.

[0065] The microbial count may be the number of microorganisms in tap water that are capable of consuming free chlorine.

[0066] Consumption intensity can be a numerical value corresponding to the degree to which microorganisms in tap water consume free chlorine per unit time.

[0067] The consumption volume can be the volume of free chlorine consumed by microorganisms in tap water per unit time.

[0068] The preset temperature influence coefficient may be a value of the effect of the water body temperature on the consumption volume calculation result.

[0069] The preset acid-base adjustment coefficient may be a value of the effect of the pH value of the water body on the consumption volume calculation result.

[0070] Specifically, during the purification process of tap water, the microorganisms present in the tap water will consume the free chlorine in the tap water to a certain extent, and the microorganisms in the tap water are also a kind of substance. Therefore, the number and type of microorganisms in the tap water are extracted from the real-time material data. The consumption intensity of free chlorine of the microorganism type in the tap water under the conditions of the water temperature, water pH value and water flow rate obtained in the above steps is obtained from the biological research website. The historical consumption intensity, historical conversion degree, historical number of microorganisms, historical water temperature, historical consumption volume, historical water pH value and historical water flow rate are obtained from the tap water purification management system, and the historical consumption intensity, historical conversion degree, historical number of microorganisms, historical water temperature, historical consumption volume, historical water pH value and historical water flow rate obtained in the above steps are calculated to obtain the preset temperature influence coefficient and the preset acid-base adjustment coefficient. When calculating the preset temperature influence coefficient and the preset acid-base adjustment coefficient, a linear regression analysis method, a regression tree analysis method, a random forest analysis method and a neural network regression analysis method can be used to calculate. The preset temperature influence coefficient, preset acid-base adjustment coefficient, consumption intensity, conversion degree, number of microorganisms, water temperature, water pH value and water flow rate are analyzed using mathematical analysis methods. The consumption volume is determined according to formula (2) and the consumption volume is included in the chlorine reaction information.

[0071] In formula (2), It reflects the total consumption potential of microorganisms in water. The more there is, the more "consumers" there are in the water body, and the more free chlorine will be consumed by microorganisms. Combined with free chlorine concentration and the degree of conversion between free chlorine and combined chlorine , which is used to measure the amount of free chlorine in water that is actually available for consumption by microorganisms. It reflects the remaining amount of free chlorine, that is, the part converted into combined chlorine is no longer available for consumption. The size directly affects the consumption volume. It combines the actual free chlorine concentration with the ratio of free chlorine to combined chlorine. In the process of microbial consumption, 20 degrees Celsius is usually used as the standard temperature, because at room temperature, the activity rate of most microorganisms is relatively stable. Therefore, It represents the deviation of water temperature from the base temperature of 20 degrees Celsius, reflecting the effect of water temperature change on the rate of free chlorine consumption by microorganisms. At the same time, many microorganisms are best active around the pH value of 7 (neutral), while water environments far from the neutral pH value (pH 7) will reduce their ability to consume free chlorine. It represents the degree of deviation from the neutral pH value (7). This deviation reflects the effect of water pH on microbial metabolism. The absolute value ( ) is because water pH values ​​lower than 7 (acidic environment) or higher than 7 (alkaline environment) will have a negative impact on the activity of microorganisms, and the reflected effects are symmetrical.

[0072] therefore, Combined water temperature and water pH Effects on the rate of free chlorine consumption by microorganisms. Water temperature and pH directly affect the metabolic activity of microorganisms, thereby affecting their efficiency in consuming free chlorine. Adjustments to environmental factors (water temperature and water pH) reflect the actual ability of microorganisms to consume free chlorine under different environmental conditions. The role of the formula (1) is to correct for environmental conditions so that the final consumption volume can accurately reflect the actual microbial activity.

[0073] Through this solution, the consumption intensity of free chlorine by different types of microorganisms in the water body is determined according to the type of microorganism, providing a basis for the subsequent reaction model. By combining the consumption intensity, degree of conversion, number of microorganisms, temperature, pH value and water flow rate, the volume of free chlorine consumed by microorganisms is calculated using a formula. The formula ensures the accuracy of the formula under different conditions by adjusting multiple environmental factors, especially by adjusting the water temperature and pH value to reflect the dynamic changes of the water body in actual operation. Incorporating the consumption volume into the chlorine reaction information helps to monitor the chlorine consumption in real time and optimize the amount of chlorine added during the water treatment process to ensure that the water quality is stable and meets the standards. At the same time, it effectively improves the accuracy and control efficiency of the chlorine reaction to ensure the safety and treatment effect of the water body.

[0074] In some embodiments, the reaction time between the substance and the free chlorine is determined based on the substance concentration, free chlorine concentration and water flow rate; the amount of chlorine added is determined based on the reaction time, free chlorine concentration, consumption volume and degree of conversion; the duration of chlorine addition is determined based on the suspended particle concentration, substance concentration, reaction time and water temperature; the dosage and duration of addition are incorporated into the addition strategy.

[0076] Reaction time can be the length of time it takes for substances in tap water to react with free chlorine.

[0077] The dosage may be the volume of free chlorine determined when adding free chlorine to tap water.

[0078] The suspended particle concentration can be the weight of suspended particles in a unit volume of tap water.

[0079] The dosing time may be the length of time determined when free chlorine is added to tap water.

[0080] Specifically, mathematical analysis methods are used to analyze substance concentration, free chlorine concentration and water flow rate to determine the reaction time between substance and free chlorine. Mathematical analysis methods are used to analyze reaction time, free chlorine concentration, consumption volume and conversion degree to determine the dosage of chlorine. Suspended particle concentration is extracted from real-time substance data, and mathematical analysis methods are used to analyze suspended particle concentration, substance concentration, reaction time and water temperature to determine the duration of addition; dosage and duration of addition are included in the addition strategy.

[0081] Through this solution, the reaction time between the substance and free chlorine is accurately calculated by combining the substance concentration, free chlorine concentration and water flow rate, thereby ensuring the full reaction of chlorine. The amount of chlorine added is calculated based on the reaction time, free chlorine concentration, consumption volume and degree of conversion to avoid excessive or insufficient chlorine addition, ensuring the consumption of chlorine in the water body and the stability of water quality. By comprehensively considering factors such as suspended particle concentration, substance concentration, reaction time and water body temperature, the duration of chlorine addition is determined to further optimize the efficiency of chlorine use. Incorporating the dosage and duration of addition into the addition strategy provides a scientific basis for real-time adjustment of chlorine addition, ensuring that the use of chlorine in the water treatment process is both efficient and economical. Through fine parameter adjustment, the flexibility and accuracy of the water treatment process are enhanced, the amount of chlorine added is effectively controlled, and the quality of tap water treatment is ensured to be up to standard and safe.

[0082] In some embodiments, a qualified range of substance concentration is obtained, and the qualified range of substance concentration is matched with the first substance concentration. If the first substance concentration is not within the qualified range of substance concentration, it is determined that the harmful substances in the tap water are not completely eliminated; the substance concentration difference is determined according to the qualified range of substance concentration and the first substance concentration; and the chlorine dosage is determined according to the substance concentration difference, reaction time, water volume, free chlorine concentration, consumption volume and conversion degree, calculated according to formula (3): (3) in, Indicates the dosage, represents the difference in substance concentration, represents the volume of water, Represents the reaction time, Indicates the free chlorine concentration, Indicates the degree of conversion. Indicates the consumed volume.

[0083] The tap water monitoring information includes the water volume. The real-time substance data includes the first substance concentration.

[0084] The qualified range of substance concentration may be a numerical range formed between a minimum substance concentration and a maximum substance concentration in tap water that has been purified, under the condition that the substance concentration in the tap water meets the purification treatment requirements.

[0085] The first substance concentration may be the amount of the substance in the tap water per unit volume of the tap water after the tap water is purified.

[0086] The substance concentration difference may be a subtraction value between the first substance concentration and a maximum value in the substance concentration qualified range.

[0087] The water volume may be the volume of tap water that needs to be purified.

[0088] Specifically, obtain the qualified range of substance concentration from the tap water purification management system. Extract the substance concentration of the tap water after purification from the real-time substance data, and determine the substance concentration of the tap water after purification as the first substance concentration. Match the first substance concentration with the qualified range of substance concentration. If the first substance concentration is not within the qualified range of substance concentration, it means that the substance concentration in the purified tap water does not meet the substance concentration standard for tap water purification, that is, the tap water purification is not completed. At this time, it is necessary to subtract the first substance concentration from the maximum value in the qualified range of substance concentration to obtain the substance concentration difference. Extract the water volume from the tap water monitoring information. Use mathematical analysis methods to analyze the substance concentration difference, reaction time, water volume, free chlorine concentration, consumption volume and conversion degree obtained in the above steps, and calculate according to formula (3) to determine the chlorine dosage.

[0089] Among them, in formula (3), the numerator is: It mainly reflects the total amount of harmful substances that need to be eliminated. Specifically, it reflects the concentration difference of harmful substances in water and the direct impact of the total water volume on the amount of chlorine added. Denominator: Taking into account several important factors that affect the amount of chlorine added, it adjusts the disinfection requirements of the molecular part to ensure that the amount of chlorine added actually and effectively achieves the disinfection effect. The logarithmic relationship reflects that within a certain period of time, the reaction between chlorine and harmful substances will gradually tend to saturation, so increasing the reaction time will not linearly increase the disinfection effect. The concentration of free chlorine and the degree of its conversion to combined chlorine determine the amount of chlorine that can actually participate in the disinfection reaction. The presence of combined chlorine will reduce the amount of chlorine that actually participates in the reaction, so Adjusted the effective concentration of free chlorine.

[0090] Through this solution, the qualified range of substance concentration is obtained and matched with the first substance concentration. If the first substance concentration is not within the qualified range, it can be determined that the harmful substances in the water have not been completely eliminated. According to the difference between the qualified range of substance concentration and the first substance concentration, the difference in substance concentration is determined to provide a basis for the subsequent calculation of the amount of chlorine added. Combining the reaction time, water volume, free chlorine concentration, consumption volume and degree of conversion, the precise amount of chlorine added is calculated using a formula. In the formula, factors such as the difference in substance concentration, reaction time, and water volume work together to ensure that the amount of chlorine added can effectively eliminate harmful substances in the water without causing excessive chlorine pollution. Through this series of steps, a quantitative and controllable solution is provided for the addition of tap water chlorine, ensuring the accuracy of the water treatment process and the safety of water quality.

[0091] In some embodiments, if the concentration of the first substance is within the qualified range of substance concentration, the qualified range of free chlorine concentration is obtained, and the free chlorine concentration is matched with the qualified range of concentration; if the free chlorine concentration is not within the qualified range of concentration, it is determined that the concentration of free chlorine in the water body exceeds the standard; based on the free chlorine concentration and the qualified range of concentration, the value of the free chlorine concentration exceeding the standard is determined; based on the water body volume and the value of the concentration exceeding the standard, the excess free chlorine volume is determined; based on the free chlorine volume, the degree of conversion and the concentration of the first substance, the residence time of the free chlorine volume in the water body volume is determined; based on the residence time, the frequency of chlorine addition is determined.

[0092] The qualified concentration range can be the numerical range formed between the minimum free chlorine concentration and the maximum free chlorine concentration when the free chlorine concentration in tap water meets the purification treatment standards.

[0093] The concentration exceeding the standard value may be the value corresponding to the portion of the free chlorine concentration in the tap water that exceeds the acceptable concentration range.

[0094] The free chlorine volume can be the volume corresponding to the excess free chlorine when the free chlorine concentration exceeds the qualified concentration range.

[0095] The residence time can be the length of time that free chlorine in tap water that exceeds the acceptable concentration range does not react with any substance in the tap water and remains in the tap water in the form of free chlorine.

[0096] The dosing frequency may be the frequency corresponding to when free chlorine is added to tap water.

[0097] Specifically, if the first substance concentration is within the qualified range of substance concentration, it means that the substance concentration in the tap water meets the purification standard of tap water at this time. In order to determine whether the free chlorine in the tap water meets the standard of purification treatment, the qualified range of concentration can be obtained from the tap water purification management system, and the free chlorine concentration is matched with the qualified range of concentration. If the free chlorine concentration is not within the qualified range of concentration, it is determined that the concentration of free chlorine in the water body exceeds the standard. At this time, it is necessary to subtract the maximum value in the qualified range of concentration from the free chlorine concentration to obtain the value of the concentration exceeding the standard of free chlorine. Subtract the value of the concentration exceeding the standard from the volume of the water body to obtain the volume of free chlorine exceeding the qualified range of concentration. The free chlorine volume, degree of conversion and first substance concentration obtained in the above steps are analyzed using a mathematical analysis method to determine the residence time of the free chlorine volume in the water body volume. The dosing frequency of chlorine corresponding to the residence time of free chlorine is obtained from the tap water purification management system, and the residence time is matched with the dosing frequency of chlorine corresponding to the residence time of free chlorine to obtain the dosing frequency corresponding to the residence time, and the dosing frequency corresponding to the residence time is determined as the dosing frequency of chlorine.

[0098] Through this solution, if the concentration of the first substance is within the qualified concentration range, the qualified concentration range of free chlorine is obtained and matched. If the free chlorine concentration exceeds this range, it is determined that the free chlorine concentration in the water exceeds the standard. According to the difference between the free chlorine concentration and the qualified concentration range, the value of the free chlorine concentration exceeding the standard is calculated. Combining the volume of the water body and the value of the concentration exceeding the standard, the excess free chlorine volume is determined to provide data support for the subsequent adjustment of chlorine. According to the excess free chlorine volume, the degree of conversion and the concentration of the first substance, the residence time of free chlorine in the water body is calculated. Combining the residence time with the reaction time, the frequency of chlorine addition is determined to ensure the stability of the chlorine concentration in the water and avoid excessive addition. Through these fine steps, while effectively adjusting the amount and frequency of chlorine use, it is ensured that the chlorine concentration in the water quality treatment process meets the standard and does not produce side effects, thereby achieving the best water quality control effect.

[0099] In some embodiments, the chlorine addition time is determined according to the suspended particle concentration, free chlorine concentration, substance concentration, water volume, reaction time and water temperature according to formula (4): (4) in, Indicates the dosing time. represents the concentration of a substance, represents the volume of water, Indicates the preset particle influence coefficient, Indicates the concentration of suspended particles. Represents the reaction time, Indicates the free chlorine concentration, Indicates the preset temperature influence coefficient, Indicates the water temperature.

[0100] The preset particle influence coefficient may be a value of the effect of the suspended particle concentration on the calculation result of the dosing time.

[0101] Specifically, historical substance concentration, historical water volume, historical suspended particle concentration, historical reaction time, historical water temperature, historical free chlorine concentration and historical addition time are obtained from the tap water purification management system, and the historical substance concentration, historical water volume, historical suspended particle concentration, historical reaction time, historical water temperature, historical free chlorine concentration and historical addition time obtained in the above steps are calculated to obtain the preset temperature influence coefficient and the preset particle influence coefficient. When calculating the preset temperature influence times and the preset particle influence coefficient, regression analysis method, regression tree analysis method, random forest analysis method and neural network regression analysis method can be used to calculate. Use mathematical analysis methods to analyze suspended particle concentration, free chlorine concentration, preset particle influence coefficient, substance concentration, water volume, preset temperature influence coefficient, reaction time and water temperature, and calculate according to formula (4) to determine the chlorine addition time.

[0102] Among them, in formula (4), the numerator is: It can be considered as the overall load of chlorine demand for tap water, that is, the total amount of substances in the water that need to be disinfected and its interaction with environmental factors. Specifically: It represents the total amount of substances in the water that need to be treated. The greater the product of substance concentration and water volume, the more time and chlorine are needed for disinfection. The effect of substance concentration has been adjusted so that a longer reaction time is required when the suspended particle concentration is higher. The relationship between reaction time and disinfection effect does not increase linearly. As the reaction time increases, the reaction efficiency increases, but gradually tends to saturation. Therefore, the reaction time is corrected in logarithmic form to avoid linear overestimation. The numerator mainly reflects the substance load in the water body that needs to be disinfected and how this load is affected by factors such as suspended particle concentration and reaction time. It is a basic calculation factor for the length of chlorine addition and represents the intensity of disinfection demand. The denominator is It reflects the factors that affect the disinfection efficiency of chlorine, especially the influence of free chlorine concentration and water temperature. To express: the higher the water temperature, the faster the chemical reaction rate is generally, thus reducing the required dosing time. Preset temperature influence coefficient Quantifying this effect means that the dosing time required is reduced at higher temperatures. The duration of chlorine addition is adjusted so that high concentrations of free chlorine and high temperatures can speed up the disinfection process and reduce the time required for chlorine addition.

[0103] Through this solution, these factors are introduced into the formula for calculation based on the suspended particle concentration, free chlorine concentration, substance concentration, water volume, reaction time and water temperature. The substance concentration, suspended particle concentration and free chlorine concentration in the formula work together to ensure that the amount and duration of chlorine addition can effectively cope with the situation of different substances in the water. Specifically, the preset particle influence coefficient combined with the suspended particle concentration can take into account the influence of suspended particles on the chlorine reaction, and then adjust the addition time. At the same time, the introduction of the temperature influence coefficient and the water temperature effectively considers the interaction between the reaction time and the water temperature. Through this calculation, the chlorine addition time is accurately determined, so that the reaction between chlorine and harmful substances in the water is completed at the best time, avoiding excessive or insufficient chlorine addition, and ensuring the stability and safety of the water quality treatment effect.

[0107] The degree of purification may be a numerical value corresponding to the degree of purification of the tap water after the tap water is purified.

[0108] The purified suspended particle concentration may be the concentration corresponding to the suspended particles in the tap water after purification treatment.

Indicates the concentration of the purified substance, Indicates the concentration of purified suspended particles. Represents the reaction time, Indicates the concentration of purified free chlorine.

[0110] Through this solution, the concentration of purified free chlorine in the purified tap water is calculated through real-time free chlorine data, so as to evaluate the consumption of free chlorine and its effectiveness. According to the real-time material data, the concentration of purified substances in the purified tap water is calculated to ensure that the residual substances in the water meet the standards. The degree of purification of tap water is comprehensively evaluated by combining factors such as the concentration of purified substances, the concentration of purified free chlorine, the reaction time and the concentration of suspended particles. This step comprehensively reflects the purification effect of the water body, taking into account the process of the reaction between free chlorine and substances, and the influence of suspended particles on the reaction, thereby providing a scientific basis for further optimizing the dosage of chlorine and purification time. Through this series of operations, not only can the use of chlorine be accurately controlled, but also the quality of tap water can be ensured to meet the standards, excessive or insufficient purification can be avoided, and ultimately the optimal water quality management can be achieved.
