[0055] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0056] In embodiment 1, Figure 1 and Figure 2 The water treatment agent adding method implementation flow provided by the embodiment of the present application is shown, and the following is described in detail as follows:

[0057] S100: Draw the process flow diagram of the sewage treatment tank, find out the water inlet and the water outlet, use the online monitoring equipment pre-deployed at the water inlet and the water outlet to collect the process indicators of the sewage, and define them as the water inlet indicators and the water outlet indicators.

[0058] According to the building layout, equipment deployment and water flow path of the sewage treatment tank and other data, draw the process flow diagram, and mark the water inlet and the water outlet of the sewage treatment tank in the process flow diagram. According to the actual production needs, deploy two groups of the same online monitoring equipment at the water inlet and the water outlet, wherein the online monitoring equipment can be a pH sensor, a dissolved oxygen sensor, a turbidimeter, a chemical oxygen demand analyzer and an ammonia nitrogen online analyzer, etc. Use the online monitoring equipment to collect the process indicators of the sewage in the sewage treatment tank. Correspondingly, the process indicators are water quality parameters such as pH, dissolved oxygen, turbidity, chemical oxygen demand and ammonia nitrogen concentration. Define the process indicators collected by the online monitoring equipment at the water inlet as the water inlet indicators, and define the process indicators collected by the online monitoring equipment at the water outlet as the water outlet indicators. In this embodiment, by comparing the water inlet indicators and the water outlet indicators, the running effect of the dosing system can be directly evaluated, and data support is provided for the adjustment of the dosing amount and the optimization of the running strategy.

[0059] S200: Mark the reflux pipeline in the process flow diagram, wherein the two ends of the reflux pipeline are located at the water inlet and the water outlet respectively, set the deployment mode of the check equipment and the intermediate storage tank in the reflux pipeline, use the check equipment to read the concentration parameters of the reflux liquid in the intermediate storage tank and define them as the check indicators, set the reflux ratio, create a multi-level verification mechanism, edit an evaluation strategy set, and judge whether the online monitoring equipment and the check equipment are abnormal.

[0060] In the sewage treatment tank, a reflux pipeline is arranged, one end of the reflux pipeline is located at the water outlet, and the other end is located at the water inlet; in actual production, necessary reflux pumps, valves and other equipment should also be arranged in the reflux pipeline; in the reflux pipeline, an intermediate storage tank is further arranged for temporarily storing the reflux liquid, and a calibration device should also be arranged in the intermediate storage tank, the calibration device is another set of online monitoring devices same as the water inlet and the water outlet; further, the reflux liquid can be bidirectionally transported by setting a diaphragm pump, a centrifugal pump or a bypass, which means that the sewage can be transported not only from the water inlet to the water outlet, but also from the water outlet to the water inlet; the advantage of this mode is that the online monitoring devices at the water inlet and the water outlet can be flushed to improve the accuracy of the sensors, and the arrangement mode is the position, arrangement information and installation parameters of the calibration device and the intermediate storage tank.

[0061] The concentration parameters of each component in the reflux liquid in the intermediate storage tank are collected by using the calibration device, and the obtained concentration parameters are defined as calibration indexes, the reflux ratio is controlled by adjusting the opening degree of the reflux pump or the water outlet valve of the intermediate storage tank, and the reflux ratio can be 10% or 20%, etc., a multi-level verification mechanism is set, and the multi-level verification mechanism means that in each reflux ratio, the water inlet index and the water outlet index are verified by using the calibration index.

[0062] For example, the chemical oxygen demand (COD) of the reflux liquid in the intermediate storage tank is measured by using the calibration device, and the total phosphorus is 5 mg / L; the reflux ratio is set to 15%, the online monitoring devices at the water inlet and the water outlet are calibrated by using the reflux liquid, and the COD in the water inlet index is 100 mg / L, and the COD in the water outlet index is 90 mg / L; the reflux ratio is increased, and the reflux ratio is set to 30%, and the COD in the water inlet index and the water outlet index is continuously collected.

[0063] An evaluation strategy set composed of several evaluation strategies is created, and the evaluation strategy is an evaluation mode for the water inlet index and the water outlet index. For the above example, the corresponding evaluation strategy can be: if the water inlet index and the water outlet index match (the difference is less than a threshold value) under each reflux ratio, it means that the online monitoring devices at the water inlet and the water outlet are normal, and if the water inlet index and the water outlet index seriously deviate from the calibration index under a certain reflux ratio, it means that the online monitoring devices or the calibration device may have faults or deviations. Whether the online monitoring devices and the calibration device are abnormal is judged by using the evaluation strategy set in combination with the water inlet index, the water outlet index and the calibration index.

[0064] S300: a balanced tree composed of a left node and a right node is created, the online monitoring device and the corresponding calibration index are written into the left node and the right node respectively, the difference value is calculated, and when the difference value is greater than a threshold value, the balanced tree is tilted.

[0065] The left node and the right node are created, and a balanced tree is generated, wherein the left node and the right node are logical nodes and are not physical processing devices, and are mainly used to show the running status of the online monitoring device; the left node and the right node are integrated to generate a balanced tree, which is a tree data structure similar to a tree in nature, and can intuitively show the hierarchical relationship and dynamic change of data in the left node and the right node; the inflow index and the check index are written into the left node, and the outflow index and the check index are written into the right node; the difference between the inflow index or the outflow index and the check index is calculated, and the greater the difference, the greater the abnormality of the online monitoring device or the check device, and the balanced tree is tilted, wherein the tilt refers to the change in angle (as shown in the accompanying drawings of the specification). Figure 1

[0066] S400: using the vibration sensor pre-installed on the production equipment, collecting real-time sensing data, setting a weight value corresponding to the vibration sensor, calculating the production capacity score of each production equipment through the real-time sensing data and the weight value, establishing the correlation between the production capacity score and the process index, taking time as the horizontal coordinate and the production capacity score and the process index as the vertical coordinate, drawing a dosing reference graph, and sending it to the dosing system.

[0067] The vibration sensor is installed on the production equipment, and the production equipment refers to the equipment that actually participates in the production operation and produces sewage. The vibration sensor is used to collect vibration data of the production equipment, wherein the vibration data includes vibration amplitude, frequency and duration, etc. The vibration data can directly reflect the running state and load condition of the production equipment. According to the importance, processing capacity, historical load, average component concentration of sewage and contribution proportion of sewage production of each production equipment, the weight value of each vibration sensor is determined. The real-time value of the vibration data is multiplied by the weight value and superimposed on the production capacity score of each production equipment, wherein the greater the production capacity score, the greater the sewage quantity or concentration. When a larger production capacity score is monitored, it means that the sewage quantity or concentration entering the sewage treatment tank may increase, and the reagent dosing amount needs to be adjusted in advance to ensure the stability of the effluent quality.

[0068] ​During the monitoring process, the productivity fraction can be used to correct the online monitoring equipment. For example, at a certain time, the productivity fraction gradually increases, but the process indicators do not change significantly, which indicates that the online monitoring equipment may have drift, misalignment, or failure. According to the time sequence, the productivity fraction is recorded, and a dynamic change graph of the productivity fraction is drawn with time as the horizontal coordinate and the productivity fraction as the vertical coordinate. It should be noted that each production equipment corresponds to a productivity fraction, and different production equipment may produce multiple pollutants in the sewage. For example, the productivity fraction of a certain production equipment is 65. According to the historical operation data, production equipment A may produce sulfate, chloride, and nitrogen oxide, and production equipment B may also produce nitrogen oxide. Therefore, the dynamic change graphs corresponding to A and B are superimposed on the same graph to obtain a dosing reference graph. In other words, the dosing reference graph is also a set of productivity fractions of production equipment that produces the same component pollutant. The dosing reference graph is sent to the dosing system and pushed to the management personnel of the sewage treatment tank, providing a data basis for the advance dosing operation of the management personnel.

[0069] In embodiment 2, Figure 3 The water treatment agent adding method implementation process provided by the embodiment of the application is shown. The steps of drawing the process flow of the sewage treatment tank and finding the water inlet and the water outlet are described in detail as follows:

[0070] S101: Collecting the operation parameters of the sewage treatment tank, wherein the operation parameters at least include turbidity, chemical oxygen demand, agitator speed, and tank body temperature.

[0071] The operation parameters of the sewage treatment tank are collected. The operation parameters should include the operation indicators (turbidity, COD, and tank body temperature) of the sewage treatment tank and the equipment operation parameters (agitator speed).

[0072] S102: Cross-verification of the process indicators by using the operation parameters.

[0073] The process indicators are cross-verified by using the operation parameters. For example, the online monitoring instrument shows that the COD in the effluent indicator suddenly decreases, the agitator speed in the tank remains normal, the effluent flow and other equipment operation are relatively stable, and the productivity fraction also does not change dramatically, which indicates that the measured value in the effluent indicator may have drift or sensor failure.

[0074] In embodiment 3, Figure 3 The water treatment agent adding method implementation process provided by the embodiment of the application is shown. The steps of collecting the process indicators of the sewage and defining the process indicators as the water inlet indicators and the water outlet indicators are described in detail as follows:

[0075] S103: Cutting the process indicators into a plurality of single items.

[0076] The process indicators are divided into several single indicators; for example, pH indicators, dissolved oxygen indicators, and turbidity indicators.

[0077] S104: Set a fluctuation range, wherein each single indicator corresponds to a fluctuation range, and when the single indicator exceeds the fluctuation range, an alarm mechanism is activated.

[0078] A fluctuation range is set for each single indicator, and if the single indicator exceeds the fluctuation range, the corresponding alarm mechanism is activated, wherein the alarm mechanism can be to notify the inspection personnel to manually sample and accurately verify the single indicator.

[0079] In embodiment 4, Figure 4 The water treatment agent adding method implementation process provided by the embodiment of the application is shown, and the steps of reading the concentration parameter of the backflow liquid in the intermediate storage tank, defining the concentration parameter as a verification indicator, setting a backflow ratio, and creating a multi-level verification mechanism are described as follows:

[0080] S201: Based on the intermediate storage tank, edit a point inspection rule, and correct the concentration parameter according to the manual inspection result.

[0081] The point inspection rule is constructed, that is, the components of the backflow liquid in the intermediate storage tank are qualitatively and quantitatively evaluated by manual sampling, the manual verification result is obtained, the concentration parameter is verified, and the authenticity and reliability of the verification equipment are ensured.

[0082] S202: Record the adjustment process of the backflow ratio, and generate a log.

[0083] The adjustment process of the backflow ratio is recorded, that is, when the backflow ratio changes, the backflow ratio before and after the change is recorded, and a log is generated.

[0084] In embodiment 5, Figure 5 The water treatment agent adding method implementation process provided by the embodiment of the application is shown, and the steps of creating a balanced tree composed of left nodes and right nodes, and writing the online monitoring equipment and the corresponding verification indicators into the left nodes and the right nodes are described as follows:

[0085] S301: Write the water inlet indicator and the verification indicator into the left node, write the water outlet indicator and the verification indicator into the right node, and calculate the difference in the left node and the right node.

[0086] The water inlet indicator and the verification indicator are written into the left node, the water outlet indicator and the verification indicator are written into the right node, the difference between the water inlet indicator and the verification indicator is calculated, and the difference between the water outlet indicator and the verification indicator is calculated.

[0087] S302: Select the display terminal of the balance tree, and dynamically update the balance tree according to a preset frequency.

[0088] The display terminal of the balance tree is determined, which can be a device terminal of a sewage treatment pool manager or a display screen in a sewage treatment site. The balance tree is updated according to a preset frequency, which can be 5 minutes or 10 minutes.

[0089] In embodiment 6, different from embodiment 1, the method further comprises:

[0090] The fluctuation range of the inflow index and the outflow index is traversed. When the difference is less than or equal to the threshold value, and the inflow index or the outflow index is out of the fluctuation range, the offset is calculated, the balance tree is tilted, the tilt angle is set, the corresponding relationship between the offset and the tilt angle is established, and the adjustment permission of the dosing system of the balance tree is opened.

[0091] If the difference is less than or equal to the threshold value, it means that the reading of the online monitoring device at the inlet and outlet is correct. If the difference is less than or equal to the threshold value, and the inflow index or the outflow index is out of the fluctuation range, it means that the inflow index or the outflow index may have a transient disturbance, that is, it fluctuates sharply in a short time. The part of the inflow index or the outflow index out of the fluctuation range is defined as the offset, the offset is divided into several intervals, and a corresponding tilt angle is set for each interval. According to the interval corresponding to the offset, the corresponding tilt angle is determined, and the balance tree is adjusted to the corresponding tilt angle. At the same time, the adjustment permission of the dosing system of the balance tree is opened, and the reagent is automatically added to the sewage treatment tank, so as to adjust the tilt angle to the initial vertical position. The advantage of this method is that the self-adaptive adjustment of the dosing system can be realized through the angle control of the balance tree.

[0092] In embodiment 7, Figure 6 The water treatment reagent adding method implementation process provided by the embodiment of the application is shown. The step of collecting real-time sensing data by using the vibration sensor pre-installed on the production equipment and setting the weight value corresponding to the vibration sensor is described in detail as follows.

[0094] The production equipment at which each vibration sensor is installed, that is, the source, is determined, and the attribute data of each source is determined. The attribute data includes: the specific installation position of the vibration sensor, the type of the equipment and the sampling frequency.

[0095] S402: draw a variation curve via the process indicators, taking time as the horizontal coordinate, and single indicators and capacity fractions as the vertical coordinates respectively, write attribute data into the corresponding variation curve via the capacity fraction, integrate all variation curves, and generate a dosing reference map.

[0096] Draw a curve taking time as the horizontal coordinate and each single indicator as the vertical coordinate, draw a curve taking time as the horizontal coordinate and capacity fraction as the vertical coordinate, superimpose the two curves on the same graph, obtain the variation curve, integrate the variation curves corresponding to all single indicators, and obtain the dosing reference map, in other words, the dosing reference map is also a set composed of variation curves, and attribute data of the production equipment is written into the variation curve according to the corresponding relationship between the production equipment and the capacity fraction.

[0097] When the management personnel queries the dosing reference map and finds that the capacity fraction fluctuates sharply (rises or falls), the dosing amount can be manually adjusted in advance.
