[0002] With the development of economy and population growth, water resource shortage problem is increasingly serious, and reclaimed water reuse as an important means to alleviate water resource pressure is widely concerned.

[0003] However, there are many challenges in the regulation of reclaimed water reuse quantity. On the one hand, the existing technology is not accurate enough in controlling the quality of reclaimed water. Many methods fail to fully consider the key water quality indicators, resulting in blind reclaimed water reuse in the case of unstable water quality, which may cause negative effects on the use equipment or environment, reduce water resource reuse efficiency, and cannot effectively alleviate the water resource shortage problem. On the other hand, there are deficiencies in the assessment of water supply stability. Some technologies only consider the water supply information, without fully combining the actual water consumption of the upstream and downstream water nodes of the reclaimed water system, so that the water supply stability index cannot accurately reflect the real water demand, and thus the water supply quantity cannot be accurately adjusted based on this. This easily causes unreasonable water supply quantity, leading to inconvenience in water use or waste of water resources. In addition, the overall reclaimed water reuse regulation system lacks completeness and closed-loop nature. The existing technology often fails to comprehensively plan key factors such as water quality, water supply and water use, and lacks effective connection and strict control between the links, making it difficult to fully guarantee the safety and reliability of the operation of the reclaimed water system.

DETAILED DESCRIPTION

[0019] Exemplary embodiments of the present disclosure will be described in detail with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure can be more thoroughly understood, and the scope of the present disclosure can be accurately conveyed to those skilled in the art. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0020] In some embodiments of the present application, referring to Figure 1 The present embodiment provides a method for dynamically adjusting the amount of reclaimed water reuse, which comprises the following steps: S100, collecting water quality information and water supply information of a reclaimed water system, and collecting water consumption of a water consumption node; wherein the water quality information includes turbidity, ammonia nitrogen concentration and chemical oxygen demand; the water supply information includes water supply amount and water pressure; S200, evaluating water quality stability according to the water quality information, and obtaining a water quality stability index; determining whether to reuse reclaimed water according to the water quality stability index; S300, if it is determined to reuse reclaimed water, evaluating water supply stability according to the water supply information, and obtaining a water supply stability index; S400, acquiring water consumption of water nodes upstream and downstream of the reclaimed water system, judging whether to adjust the water supply stability index according to the water consumption, if it is judged to adjust, adjusting the water supply stability index according to the water consumption to obtain a final value of the water supply stability index; S500, judging whether to adjust the water supply according to the final value of the water supply stability index, if it is judged to adjust, obtaining an adjustment value of the water supply according to the final value of the water supply stability index.

[0021] It can be understood that, first, from the perspective of rational utilization of water resources, by collecting water quality information such as turbidity, ammonia nitrogen concentration and chemical oxygen demand of the reclaimed water system, as well as water supply information including water supply amount and water pressure, and water consumption of water nodes, the entire reclaimed water system can be comprehensively and accurately mastered. Based on these detailed data, water quality stability evaluation is carried out and a water quality stability index is obtained, and then it is judged whether to reuse reclaimed water, which makes the reuse of reclaimed water more scientific and reasonable, avoids the negative effects that may be caused by blind reuse, ensures that reuse is carried out only when the water quality is stable and suitable, improves the reuse efficiency of water resources, and effectively alleviates the problem of water resource shortage. Secondly, in terms of ensuring water supply stability, after judging that reclaimed water can be reused, the water supply stability is evaluated to obtain a water supply stability index, and the index is adjusted considering the water consumption of water nodes upstream and downstream of the reclaimed water system, and finally a final value of the water supply stability index is obtained, which can fully combine the actual water consumption to accurately control the water supply stability. Based on the final value of the water supply stability index, it is judged whether to adjust the water supply amount and the adjustment value is determined, which can ensure that the water supply can always meet the water demand and maintain a stable water supply state, avoiding the inconvenience of water use or waste of water resources caused by unreasonable water supply amount. Furthermore, from the safety and reliability of the overall operation, the present application comprehensively covers key elements such as water quality, water supply and water use, and strictly controls the reclaimed water reuse process at each link. From whether the water quality is suitable for reuse to whether the water supply is stable, and then flexibly adjusting the water supply according to the actual water consumption, a complete and closed-loop control system is formed, which greatly improves the safety and reliability of the operation of the reclaimed water system.

[0022] Specifically, the water supply amount is the reclaimed water reuse amount.

[0023] In some embodiments of the present application, when the water quality stability is evaluated according to the water quality information and the water quality stability index is obtained, it includes: The threshold values corresponding to turbidity, ammonia nitrogen concentration and chemical oxygen demand are set in advance respectively; If the turbidity, ammonia nitrogen concentration and chemical oxygen demand are all less than the corresponding threshold values, the water quality stability index is a first index; Otherwise, the water quality stability index is a second index; Wherein, the first index > the second index.

[0024] In some embodiments of the present application, when determining whether to reuse the reclaimed water according to the water quality stability index, the method comprises: If the water quality stability index is the first index, it is determined to reuse the reclaimed water; If the water quality stability index is the second index, it is determined not to reuse the reclaimed water.

[0025] It can be understood that, by pre-setting the threshold values corresponding to turbidity, ammonia nitrogen concentration and chemical oxygen demand respectively, the present application can define the water quality condition with clear and quantitative standards. When the turbidity, ammonia nitrogen concentration and chemical oxygen demand are all less than the corresponding threshold values, a higher first index is given as the water quality stability index, and vice versa, a lower second index is given, so that the measurement of water quality stability is more intuitive and clear. Based on this water quality stability index, it is determined whether to reuse the reclaimed water. If it is the first index, it is determined to reuse the reclaimed water, and if it is the second index, it is not reused, so that the decision of reclaimed water reuse becomes scientific and reasonable. Not only is it helpful to efficiently utilize water resources and avoid a series of problems that may be caused by unstable water quality, such as damage to reuse facilities and adverse effects on subsequent use scenarios, but also it can realize the recycling of water resources, improve the utilization efficiency of water resources and reduce the dependence on fresh water resources under the premise of ensuring water quality safety.

[0026] In some embodiments of the present application, when it is determined to reuse the reclaimed water, the water supply stability is evaluated according to the water supply information to obtain a water supply stability index, and the method comprises: A minimum water supply amount and a minimum water pressure are set. If the water supply amount is greater than or equal to the minimum water supply amount, and the water pressure is greater than or equal to the minimum water pressure, the water supply stability index is a first water supply index; If the water supply amount is greater than or equal to the minimum water supply amount, and the water pressure is less than the minimum water pressure, the water supply stability index is a second water supply index; If the water supply amount is less than the minimum water supply amount, and the water pressure is greater than or equal to the minimum water pressure, the water supply stability index is a second water supply index; If the water supply amount is less than the minimum water supply amount, and the water pressure is less than the minimum water pressure, the water supply stability index is a third water supply index; Wherein, the first water supply index > the second water supply index > the third water supply index.

[0027] It can be understood that the present application can accurately evaluate the water supply stability, and by setting two key indicators of the minimum water supply amount and the minimum water pressure, different water supply situations can be distinguished in detail, and the corresponding water supply stability index is generated to provide accurate basis for subsequent decision-making. When the water supply amount and the water pressure both meet the minimum value requirement, a higher first water supply index is given, indicating that the water supply stability is good in this case, and the relevant personnel can intuitively understand that the water supply is in an optimal state; when one of them does not meet the requirement, a second water supply index is given, reflecting that the water supply stability has decreased; if neither of them meets the requirement, a third water supply index is given, reflecting poor water supply stability. This hierarchical evaluation method helps to comprehensively and accurately grasp the water supply situation, so as to take corresponding measures in time to ensure the water supply stability in the process of reclaimed water reuse, improve the water resource utilization efficiency and the reliability of the water supply system.

[0028] In some embodiments of the present application, when the water consumption of the upstream and downstream water use nodes of the reclaimed water system is obtained, and whether to adjust the water supply stability index is determined according to the water consumption, comprising: The total value of the water consumption of all water use nodes per day is calculated, the maximum value of the water consumption in the total value of the water consumption in the preset number of days is screened, and whether to adjust the water supply stability index is determined according to the maximum value of the water consumption.

[0029] In some embodiments of the present application, when the maximum value of the water consumption is determined, whether to adjust the water supply stability index is determined according to the maximum value of the water consumption, comprising: If the maximum value of the water consumption is greater than the water supply amount, it is determined that the water supply stability index is not adjusted; Otherwise, it is determined that the water supply stability index is adjusted.

[0030] In some embodiments of the present application, when the water supply stability index is adjusted according to the water consumption, the final value of the water supply stability index is obtained, comprising: The difference between the water supply amount and the maximum value of the water consumption is calculated; An adjustment coefficient is obtained according to the difference, wherein the difference and the adjustment coefficient are inversely proportional, and the value range of the adjustment coefficient is 1> adjustment coefficient> 0; The final value of the water supply stability index is the product value of the water supply stability index and the adjustment coefficient.

[0031] It can be understood that the application calculates the total water consumption value in units of days and screens the maximum value in the preset number of days, which can accurately grasp the water consumption peak situation and provide accurate data basis for subsequent decision-making. Secondly, by comparing the maximum water consumption value with the water supply amount to determine whether to adjust the water supply stability index, a balance between water supply capacity and actual water demand can be found. If the maximum water consumption value is greater than the water supply amount, the index is not adjusted, which can avoid the irrationality caused by excessive adjustment in the case of insufficient water supply; and when the maximum water consumption value is less than or equal to the water supply amount, adjustment is made, which can flexibly optimize the water supply stability according to the actual supply and demand situation. Furthermore, the adjustment coefficient is obtained according to the difference between the water supply amount and the maximum water consumption value, and the difference and the adjustment coefficient are inversely proportional, which can finely adjust the water supply stability index according to different supply and demand gaps, so that the final water supply stability index terminal value is more in line with the actual water supply stability, which helps to improve the accuracy and scientificity of the water supply stability evaluation of the entire reclaimed water system, and better guarantees the stable operation of the reclaimed water system.

[0032] In some embodiments of the present application, when determining whether to adjust the water supply amount according to the water supply stability index terminal value, the method comprises: setting an index threshold value, if the water supply stability index terminal value is less than the index threshold value, it is determined to adjust the water supply amount; otherwise, it is determined not to adjust the water supply amount.

[0033] In some embodiments of the present application, when obtaining the water supply amount adjustment value according to the water supply stability index terminal value, the method comprises: determining an adjustment coefficient according to the water supply stability index terminal value, and the adjustment coefficient is inversely proportional to the water supply stability index terminal value, wherein 1 < adjustment coefficient < 2; the water supply amount adjustment value is the product value of the adjustment coefficient and the water supply amount.

[0034] It can be understood that, on the one hand, setting the index threshold value can provide a clear quantitative standard for the adjustment of the water supply amount, making the decision-making process more scientific and objective, avoiding blind adjustment of the water supply amount, and thus ensuring the operation of the water supply system in a stable state, reducing unnecessary resource waste and system loss. On the other hand, by determining the adjustment coefficient according to the water supply stability index terminal value and inversely proportional relationship, and setting a reasonable adjustment coefficient range, the water supply amount can be flexibly and accurately adjusted according to the water supply stability. When the water supply stability is poor, i.e. the index terminal value is low, a larger adjustment coefficient is used to make a larger adjustment to the water supply amount, so as to quickly restore the water supply stability; and when the water supply stability is good, the adjustment coefficient is small, and the adjustment range of the water supply amount is small, so as to maintain the stable state of the water supply and ensure the efficient, stable and reliable operation of the water supply system.

[0035] On the other hand, referring to Figure 2As shown, the application also provides a dynamic control system for reclaimed water reuse amount, which is used for applying the dynamic control method for reclaimed water reuse amount, and comprises: A collection module is configured to collect water quality information and water supply information of the reclaimed water system, and collect water consumption of water consumption nodes; wherein the water quality information comprises turbidity, ammonia nitrogen concentration and chemical oxygen demand; and the water supply information comprises water supply amount and water pressure. A judgment module is configured to perform water quality stability evaluation according to the water quality information, and obtain a water quality stability index; and determine whether to perform reclaimed water reuse according to the water quality stability index. A preliminary evaluation module is configured to, if it is determined to perform reclaimed water reuse, perform water supply stability evaluation according to the water supply information, and obtain a water supply stability index. An evaluation adjustment module is configured to obtain water consumption of upstream and downstream water consumption nodes of the reclaimed water system, determine whether to adjust the water supply stability index according to the water consumption, and if it is determined to adjust, adjust the water supply stability index according to the water consumption, and obtain a final value of the water supply stability index. An adjustment module is configured to determine whether to adjust the water supply amount according to the final value of the water supply stability index, and if it is determined to adjust, obtain an adjustment value of the water supply amount according to the final value of the water supply stability index.

[0036] It can be understood that, first, the collection module comprehensively collects water quality information (such as turbidity, ammonia nitrogen concentration and chemical oxygen demand), water supply information (water supply amount and water pressure) of the reclaimed water system, and water consumption of water consumption nodes. Such comprehensive data collection lays a solid foundation for subsequent precise control. By mastering the water quality information, the quality status of the reclaimed water can be understood in a timely manner, so as to ensure that it meets the reuse standard and guarantees the safety of reuse. The collection of water supply information helps to grasp the basic situation of water supply and provides a basis for reasonable allocation of water resources. The collection of water consumption of water consumption nodes starts from the demand side, so that the control is more targeted. The judgment module performs water quality stability evaluation according to the water quality information and obtains a water quality stability index, so as to determine whether to perform reclaimed water reuse. This link effectively guarantees the safety of reclaimed water reuse. Only when the water quality stability reaches a certain standard, can the reuse be allowed, which greatly reduces various risks that may be caused by water quality problems, such as corrosion of water consumption equipment, influence on production process, and secondary pollution to the environment, etc.

[0037] Secondly, after determining that reclaimed water can be reused, the preliminary assessment module conducts a water supply stability assessment based on water supply information and obtains a water supply stability index, providing an important reference for subsequent regulation. This ensures that water supply stability is fully considered during the reuse process, avoiding problems such as water waste or unmet water demand caused by unstable water supply. The assessment and adjustment module obtains the water consumption of upstream and downstream water-using nodes in the reclaimed water system and determines whether to adjust the water supply stability index accordingly. If adjustment is needed, the final value of the water supply stability index is obtained. This step further optimizes the accuracy of regulation, taking into account the dynamic changes in water consumption at upstream and downstream water-using nodes, making the water supply stability index more closely reflect actual water use, thus providing a more accurate basis for the reasonable adjustment of water supply.

[0038] Finally, the adjustment module determines whether to adjust the water supply based on the final value of the water supply stability index. If adjustment is required, the adjustment value of the water supply is obtained, which realizes precise control of the water supply. This avoids waste caused by excessive water supply and prevents water demand from being affected by insufficient water supply, greatly improving the efficiency of water resource utilization and enabling the reclaimed water system to operate more stably and efficiently, thus achieving the sustainable use of water resources.
