Description

Technical Field

[0001] The present invention belongs to the technical field of sewage treatment, and in particular relates to a high-efficiency automated sewage sample collection and analysis system. Background Art

[0002] With the acceleration of industrialization and rising urbanization, the total amount of sewage discharge continues to grow. As a core component of environmental pollution prevention and control, water quality monitoring is becoming increasingly important. Currently, sewage monitoring is widely used in municipal pipe networks, industrial wastewater treatment, and water source protection. Government regulators, sewage treatment companies, and environmental research institutions all have an urgent need for real-time, accurate water quality data.

[0003] In traditional sewage treatment, sampling points are generally set at the sewage outlet to sample sewage parameters to determine whether the sewage treatment is qualified, and then discharge it after it is qualified. This method can only determine the final sewage treatment situation. Since the sewage treatment process has multiple treatment steps, when sewage discharge is unqualified, it is impossible to know which environment in the treatment process has a problem, and thus it is impossible to prescribe the right medicine. In addition, when collecting sewage, manual sampling is mostly used, and then analysis is carried out. Manual sampling is limited by time and manpower, and it is difficult to achieve high-frequency, multi-point synchronous collection. In addition, manual analysis is not accurate enough and takes too much time, which affects the efficiency and accuracy of judgment. Summary of the Invention

[0015] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0016] Figure 1 This is a system structure diagram of the present invention. DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] In one embodiment, a highly efficient and automated sewage sample collection and analysis system is disclosed, such as Figure 1 As shown, the analysis system includes: Deployment module, which sets multiple sewage sampling and monitoring points in sequence according to the sewage treatment process steps; The acquisition module is used to obtain sewage sampling monitoring points and sewage-related parameter information; Self-analysis module: The self-analysis module is used to process and analyze the acquired parameter information to determine whether the sewage discharge meets the standards; The traceability module, when sewage discharge does not meet the standards, analyzes the data information within the process steps of the sewage sampling monitoring point to trace the problem.

[0019] Through the above scheme, this application sets up multiple sewage sampling monitoring points according to the sewage treatment process steps, so that each treatment process link can be monitored. Once an abnormality occurs in sewage treatment, it can be known in time which link has a problem, reducing the problem investigation time. After a problem occurs, it can be analyzed according to data information such as equipment parameters, process parameters and drug dosage parameters in the link to trace the source of the problem, so as to facilitate symptomatic treatment; in addition, when conducting sewage analysis, the sewage can be automatically integrated and analyzed through the installed multiple detection equipment, and the sewage pollution situation can be quickly and accurately determined, thereby judging whether the sewage treatment is qualified. Its sampling is not restricted by time, manpower, etc., and does not require human analysis, and the detection results and efficiency are also significantly improved.

[0020] The working method of the self-analysis module is: based on the collected sewage detection indicators, obtain the parameter values ​​of each detection indicator , compare the parameter values ​​of each test indicator item with the standard parameter value when the standard is met Compare and compare, if the standard parameter value is not reached, it is judged that the sewage discharge does not meet the standard; At the same time, through the formula Obtain comprehensive pollution deviation value ,when When , it is judged that the sewage discharge does not meet the standards; in, is the total number of sewage detection indicators, is the weight coefficient of the i-th detection index item, is the pollution deviation judgment threshold.

[0021] The above scheme provides an analytical method for self-testing sewage. First, the parameter values ​​of various sewage test indicators are collected, such as chemical oxygen demand (COD) obtained by online COD analyzer, biochemical oxygen demand (BOD) obtained by online BOD analyzer, and the ), through the ammonia nitrogen analyzer ammonia nitrogen ( ) etc., and then compare the parameter values ​​of each test indicator item with the standard parameter values ​​when the standard is met. Compare to determine whether the sewage treatment is qualified. For example, according to the Class A standard, the chemical oxygen demand (COD) of the treated water is ≤ 50 mg / L, so the standard parameter value is set. When the chemical oxygen demand is not less than 50, it is judged that the sewage discharge is not up to standard and the sewage treatment is abnormal. Obtain comprehensive pollution deviation value ,when When the sewage discharge does not meet the standards, is the total number of sewage detection indicators, is the weight coefficient of the i-th detection index item, which is determined according to the degree of sewage pollution impact. The threshold for judging pollution deviation is determined based on experience. This method not only tests each parameter of sewage separately, but also conducts comprehensive analysis based on multiple indicators. To judge the comprehensive pollution situation, if The smaller the difference, the closer the parameter values ​​of the various detection indicators are to the judgment threshold or exceed the judgment threshold, and the more unqualified the sewage treatment is. Therefore, a comprehensive analysis combining multiple detection indicators can more accurately detect the pollution situation of sewage.

[0022] The working method of the self-analysis module also includes: when it is determined that the sewage discharge meets the standards, Collect the comprehensive pollution deviation value of the effluent of the sewage treatment process step m times within a certain time period , and formulate the curve function of comprehensive pollution deviation value changing with the number of collection times At the same time, the historical data of the same processing batch in the processing step is searched from the database to determine the standard comprehensive contamination deviation value at each collection time. , get the deviation value of each collection ; Calculate the sewage treatment status value through the formula , ; when If the condition of sewage treatment is good, it is judged that there is abnormality in sewage treatment in the sewage treatment process step; in, for The first collection in time, for The last collection within the time, is the proposed pollution deviation judgment threshold change curve function, is the deviation value of the j-th collection, for The number of acquisitions within a certain time period where the deviation value exceeds the average deviation value, The threshold value for judging the sewage treatment status.

[0023] The above solution provides another method for the self-analysis module to work. First, when it is determined that the sewage discharge meets the standards, Collect the comprehensive pollution deviation value of the effluent of the sewage treatment process step m times within a certain time period , and formulate the curve function of comprehensive pollution deviation value changing with the number of collection times At the same time, the historical data of the same processing batch in the processing step is searched from the database to determine the standard comprehensive contamination deviation value at each collection time. , get the deviation value of each collection The larger the value, the greater the gap with the standard value, and the greater the possibility of hidden dangers. Then the sewage treatment status value is calculated by the formula , ;formula It indicates the difference between the change of the comprehensive pollution deviation value and the change of the pollution deviation judgment threshold. Although the sewage discharge has been detected to meet the standard, if the comprehensive pollution deviation value is always close to the judgment threshold, it means that there may be potential abnormal problems in the sewage treatment. Therefore, when The larger the value, the better the sewage treatment effect, and the smaller the value, the worse the sewage treatment effect. Then the sewage treatment process step has the greater hidden danger of sewage treatment abnormality. Formula represents the mean of the deviation values, and It indicates an out-of-tolerance situation of the deviation value relative to the average deviation. Obviously, when the values ​​of the two are larger, it means that there is a greater hidden danger of sewage treatment abnormality in the sewage treatment process step. Therefore, combined with the formula Conduct comprehensive analysis to obtain sewage treatment status values , when the sewage treatment status value The larger the value of is, the better the sewage treatment effect is. hour, The threshold for judging the sewage treatment condition is determined based on experience. If it is good, the sewage treatment condition is judged to be good. Otherwise, it is judged that there is an abnormality in the sewage treatment process step. In this way, the effect of sewage treatment and the hidden dangers of abnormal treatment in the treatment process step can be judged when the sewage treatment meets the standards. When the sewage treatment effect is good, it is maintained. When the sewage treatment effect is poor, it indicates that there is a hidden danger of abnormal treatment. It should be checked and handled in time to ensure the treatment efficiency and ensure the qualified discharge of sewage.

[0024] The traceability module works as follows: when sewage discharge does not meet the standards, Obtain the equipment performance parameters, process parameters and reagent dosage parameters in the process step, and obtain the corresponding comprehensive pollution deviation value, match each parameter with the obtained comprehensive pollution deviation value at the same time stamp, and calculate the correlation coefficient respectively. 、 、 , when When , it is judged that the reason why the sewage discharge does not meet the standards is related to the equipment performance; when When , it is judged that the reason why the sewage discharge does not meet the standards is related to the process parameter settings; when When , it is judged that the reason why the sewage discharge does not meet the standards is related to the proportion of the chemical dosage; Correlation coefficient The acquisition method is: when it is judged that the sewage treatment does not meet the standards, Each time the performance parameters of the equipment are adjusted, and various performance parameters are obtained, each performance parameter is given a certain weight, and the weighted performance status value of the equipment is obtained. , and obtain the comprehensive pollution deviation value under the corresponding performance status value , through the formula The correlation coefficient is obtained, A is the sample size, and , is the average equipment performance status value of all samples A, is the average comprehensive contamination deviation value of all samples A; Correlation coefficient The acquisition method is: when it is judged that the sewage treatment does not meet the standards, Each time, the process parameters in the process steps are adjusted and various process parameters are obtained. After assigning a certain weight to each process parameter, the weighted process parameter value is obtained. , and obtain the comprehensive pollution deviation value under the corresponding process parameter value , through the formula The correlation coefficient is obtained, is the sample size, and , is the average process parameter value of all samples B, is the average comprehensive contamination deviation value of all samples B; Correlation coefficient The acquisition method is: when it is judged that the sewage treatment does not meet the standards, Adjust the dosage ratio within each process step and obtain the dosage ratio for each dose. , and obtain the comprehensive pollution deviation value under the corresponding dosage ratio , through the formula The correlation coefficient is obtained, is the sample size, and , is the average drug dosage ratio of all samples C, is the average comprehensive contamination deviation value of all samples C.

[0025] The above solution provides a specific working method of the traceability module. When it is judged that the sewage discharge does not meet the standards, it means that there is a problem in the treatment process step. Therefore, during the detection cycle Obtain the equipment performance parameters, process parameters and reagent dosage parameters in the process step, and obtain the corresponding comprehensive pollution deviation value, match each parameter with the obtained comprehensive pollution deviation value at the same time stamp, and calculate the correlation coefficient respectively. 、 、 , correlation coefficient The acquisition method is: when it is judged that the sewage treatment does not meet the standards, Each time the performance parameters of the equipment are adjusted, and various performance parameters are obtained, each performance parameter is given a certain weight, and the weighted performance status value of the equipment is obtained. , and obtain the comprehensive pollution deviation value under the corresponding performance status value , through the formula The correlation coefficient is obtained, A is the sample size, and , is the average equipment performance status value of all samples A, is the average comprehensive contamination deviation value of all samples A; the linkage coefficient The acquisition method is: when it is judged that the sewage treatment does not meet the standards, Each time, the process parameters in the process steps are adjusted and various process parameters are obtained. After assigning a certain weight to each process parameter, the weighted process parameter value is obtained. , and obtain the comprehensive pollution deviation value under the corresponding process parameter value , through the formula The correlation coefficient is obtained, is the sample size, and , is the average process parameter value of all samples B, is the average comprehensive contamination deviation value of all samples B; the correlation coefficient The acquisition method is: when it is judged that the sewage treatment does not meet the standards, Adjust the dosage ratio within each process step and obtain the dosage ratio for each dose. , and obtain the comprehensive pollution deviation value under the corresponding dosage ratio , through the formula The correlation coefficient is obtained, is the sample size, and , is the average drug dosage ratio of all samples C, is the average comprehensive contamination deviation value of all samples C; generally speaking, the larger the correlation coefficient, the stronger the correlation, so when the correlation coefficient is obtained 、 、 Afterwards, when When , it is judged that the reason for the sewage discharge not meeting the standards is related to the equipment performance, indicating that there is a high possibility of equipment performance problems; when When , it is judged that the reason for the sewage discharge not meeting the standards is related to the process parameter settings, indicating that there is a high possibility that there is a problem with the set process parameters; when When the problem occurs, it is determined that the reason for the sewage discharge not meeting the standards is related to the proportion of chemical dosage, indicating that there is a high possibility that there is a problem with the proportion of chemical dosage. In this way, when sewage discharge is abnormal, it is possible to promptly know which treatment link has the problem, reducing the time for problem investigation. After the problem occurs, it can be analyzed based on data information such as equipment parameters, process parameters, and chemical dosage parameters in the link to trace the source of the problem, thereby facilitating symptomatic treatment.
