Description

[0002] Total phosphorus determination in circulating water is a commonly used water quality monitoring method to assess the concentration of total phosphorus in water bodies. Total phosphorus refers to the sum of dissolved and suspended phosphorus in water. It is an important indicator of water quality because it is closely related to problems such as eutrophication and algal blooms.

[0003] In the existing technology, the total phosphorus content of circulating water is closely related to the processes involved before circulating water. However, there is no technology to measure or adjust the total phosphorus content by combining the conditions of the previous processes of circulating water. This results in poor accuracy of total phosphorus measurement in circulating water, which is not conducive to subsequent process management.

[0004] Therefore, improving the accuracy of total phosphorus determination in circulating water is a technical problem that needs to be solved. Summary of the Invention

[0063] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] This application provides a method for determining total phosphorus in circulating water, such as... Figure 1 As shown, the method includes the following steps:

[0065] Step S101: Obtain real-time flow records of circulating water and determine the front flow record based on the real-time flow records of circulating water.

[0066] In this embodiment, the real-time flow recorder of the circulating water records the flow-related information of the circulating water, and the leading-edge flow recorder is the flow record of the circulating water before this point.

[0067] Step S102: Construct an attribute comparison array for each process based on the frontier flow record, and determine the influence of each process.

[0068] In this embodiment, the attribute operation parameters are parameters that affect total phosphorus, such as time, pH, and temperature, involved in the process.

[0069] In some embodiments of this application, an attribute comparison array corresponding to each process is constructed based on the frontal flow record, and the influence of each process is determined, including:

[0070] The frontier flow records the operating parameters for each process;

[0071] Calculate the causal index between each operating parameter and the total phosphorus content in the process, and take the operating parameter whose causal index exceeds the first causal index as the attribute operating parameter;

[0072] Operating parameters whose causal index exceeds the second causal index but does not exceed the first causal index are considered as operating parameters to be investigated.

[0073] The adjustment ratio coefficient is determined based on the specific type of operating parameter to be investigated, and the average value of the second causal index and the first causal index is used as the average causal index.

[0074] The product of the adjustment ratio coefficient and the average causal index is used as the standard causal index, and the operational parameters whose causal index exceeds the standard causal index are used as attribute operational parameters.

[0075] Obtain the feature values ​​from the attribute execution parameters, construct an attribute comparison array, and determine the influence of each process.

[0076] In this embodiment, the causal index is a nonlinear interdependence index, which is based on state space reconstruction and nearest neighbor distance methods to determine the direction and magnitude of causal relationships. For two independent systems or factors X and Y, the state spaces of the two systems are established according to state space reconstruction theory.

[0077] For a sample point x in the state space X n x rn，1 , ..., x rn，k 。 represents x n Calculate x from the k nearest neighbors in the state space X. n The average Euclidean distance to the k nearest neighbors;

[0078]

[0079] For a sample point y in the state space Y n y sn，1 , ..., y sn，k Indicates y n Find the k nearest neighbors in state space Y, map them to state space X, and compute x. n with k nearest neighbors x sn，1 , ..., x sn，k The average Euclidean distance;

[0080]

[0081] To simplify the calculation, we can use x n The average distance to all N sample points;

[0082]

[0083] The nonlinear interdependence index, based on the state-space method, determines the causal relationship between systems according to the mapping relationship in the state space. It is defined as follows:

[0084]

[0085] By definition, 0 < s X→Y ≤1, when S X→Y As S approaches 0, systems X and Y are independent; when S... X→Y When the value is significantly greater than 0, there is a causal relationship from system X to Y, and the closer it is to 1, the stronger the causal relationship.

[0086] It should be noted that other indicators that can characterize causal relationships are also acceptable; this application only provides one specific method.

[0087] In this embodiment, the characteristic values ​​in the attribute operation parameters are used to construct an attribute comparison array and determine the influence of each process. The characteristic values ​​are the mean, the most frequent value, the peak value, the minimum value, etc.

[0088] [a1, a2, a3...an] represents the feature values ​​among the n attribute parameters;

[0089] [b1, b2, b3...bn] represents the preset feature value range among n attribute running parameters;

[0090] Compare a1 and b1, a2 and b2, ..., an and bn. The difference between the two corresponds to an influence quantity.

[0091] Step S103: Determine the initial total phosphorus content in the circulating water, and determine the accuracy of the initial total phosphorus content based on the influence of each process and the initial total phosphorus content.

[0092] In some embodiments of this application, the accuracy of detecting the initial total phosphorus amount based on the influence of each process and the initial total phosphorus amount includes:

[0096] Where P is the accuracy of the initial total phosphorus amount, α is the conversion coefficient, Q0 is the total phosphorus amount after the front process is completed, exp is the exponential function, W is the total influence amount, W0 is the reasonable range of influence amounts corresponding to the different processes involved, k1 is the first constant, and Q is the initial total phosphorus amount.

[0097] In this embodiment, For the predicted total phosphorus content, This indicates the correction made by the influence of multiple processes.

[0098] Step S104: If the accuracy of the initial total phosphorus amount meets the preset requirements, then retain the initial total phosphorus amount and output it as the target initial total phosphorus amount.

[0099] Step S105: Otherwise, obtain the real-time properties of the circulating water, and correct the initial total phosphorus amount based on the influence of each process and the real-time properties of the circulating water, and output the target initial total phosphorus amount.

[0100] In this embodiment, the real-time properties of the circulating water include pH value, temperature, and impurity content.

[0101] In some embodiments of this application, the initial total phosphorus amount is corrected based on the influence of each process and the real-time properties of the circulating water, and the output is the target initial total phosphorus amount, including:

[0102] The second influencing factor is determined based on the real-time property parameters of each circulating water and their corresponding reasonable ranges, and the influencing factor of each process is taken as the first influencing factor.

[0103] The correction factor is determined based on the first and second influencing factors, and the initial total phosphorus amount is corrected to obtain the target initial total phosphorus amount.

[0104] In this embodiment, a second influencing factor is corresponding to the difference between each real-time property parameter of circulating water and its corresponding reasonable range.

[0105] In this embodiment, the initial total phosphorus amount is corrected, i.e., correction factor * initial total phosphorus amount = target initial total phosphorus amount.

[0106] Step S106: Based on the historical records of total phosphorus in circulating water and the records of multiple measured indicators, construct a matching relationship between the historical records of total phosphorus in circulating water and the records of multiple indicators.

[0107] In this embodiment, multiple measurement indicators are recorded as economic indicators, performance indicators, etc., to describe the different energy consumption situations achieved with different total phosphorus contents.

[0108] In some embodiments of this application, a matching relationship is constructed between the historical records of total phosphorus in circulating water and the records of multiple measured indicators, including:

[0109] Based on the historical records of total phosphorus in circulating water and records of multiple measurement indicators, multiple initial measurement indicators were determined for each total phosphorus range.

[0110] Based on the error in total phosphorus content, multiple initial measurement indicators were corrected to obtain the target measurement indicators;

[0111] Establish a matching relationship between each total phosphorus range and its corresponding target measurement index.

[0112] Step S107: Based on the initial target total phosphorus amount and matching relationship, determine multiple measurement indicators and perform subsequent measurements accordingly.

[0113] By applying the above technical solutions, real-time flow records of circulating water are obtained, and the leading edge flow record is determined based on these records. An attribute comparison array corresponding to each process is constructed based on the leading edge flow record, and the influence quantity of each process is determined. The initial total phosphorus content in the circulating water is measured, and the accuracy of the initial total phosphorus content is detected based on the influence quantity of each process and the initial total phosphorus content. If the accuracy of the initial total phosphorus content meets the preset requirements, the initial total phosphorus content is retained and output as the target initial total phosphorus content. Otherwise, real-time properties of the circulating water are obtained, and the initial total phosphorus content is corrected based on the influence quantity of each process and the real-time properties of the circulating water, and then output as the target initial total phosphorus content. A matching relationship is constructed between the historical total phosphorus content and multiple indicator records in the circulating water based on historical total phosphorus content and multiple indicator records. Multiple indicator records are determined based on the target initial total phosphorus content and the matching relationship, and subsequent measurements are performed accordingly. This application improves the accuracy and reliability of total phosphorus measurement by detecting the accuracy of the initial total phosphorus content based on the influence quantity of each process and the initial total phosphorus content.

The product of the adjustment ratio coefficient and the average causal index is used as the standard causal index, and the operational parameters whose causal index exceeds the standard causal index are used as attribute operational parameters. Obtain the feature values ​​from the attribute execution parameters, construct the attribute comparison array, and determine the influence of each process; The third module is used for: Each process is pre-assigned a different impact weight, and the total impact is determined based on the impact weight and the impact amount. The accuracy of determining the initial total phosphorus amount is based on the total influence amount and the initial total phosphorus amount; Where P is the accuracy of the initial total phosphorus amount, α is the conversion coefficient, Q0 is the total phosphorus amount after the front process is completed, exp is the exponential function, W is the total influence amount, W0 is the reasonable range of influence amounts corresponding to the different processes involved, k1 is the first constant, and Q is the initial total phosphorus amount. The fifth module is used for: The second influencing factor is determined based on the real-time property parameters of each circulating water and their corresponding reasonable ranges, and the influencing factor of each process is taken as the first influencing factor. The correction factor is determined based on the first and second influencing factors, and the initial total phosphorus amount is corrected to obtain the target initial total phosphorus amount. Module 6 is used for: Based on the historical records of total phosphorus in circulating water and records of multiple measurement indicators, multiple initial measurement indicators were determined for each total phosphorus range. Based on the error in total phosphorus content, multiple initial measurement indicators were corrected to obtain the target measurement indicators; Establish a matching relationship between each total phosphorus content range and its corresponding target measurement index; Based on the difference between each real-time property parameter of circulating water and its corresponding reasonable range, there is a second influencing factor; and the initial total phosphorus amount is corrected, that is, the correction factor * the initial total phosphorus amount = the target initial total phosphorus amount.
