Description

Technical Field

[0001] The present invention relates to the technical field of wastewater defluorination control, and in particular to a wastewater defluorination control system suitable for a self-crystallizing fluidized bed. Background Art

[0002] Self-crystallizing fluidized bed technology is primarily used to treat fluoride-containing wastewater, especially when the fluoride concentration in the wastewater is much higher than 5000 ppm. This technology can efficiently remove fluoride from the wastewater through a series of process steps. First, the high-concentration fluoride-containing wastewater enters the pre-stage chemical coagulation reaction tank, where a calcium-containing precipitant is added to precipitate calcium fluoride sludge. Subsequently, the supernatant is diluted and flows into the fluidized bed. The pH value is adjusted and appropriate reagents are added. The resulting calcium fluoride crystals are formed in the fluidized bed and discharged. During this process, the upstream velocity is controlled to form a fluidized state, and the tank is filled with a carrier, making the calcium fluoride crystals easy to separate and recover. Finally, the treated effluent can be recycled or discharged, achieving efficient fluoride removal and recycling.

[0003] However, existing technologies are unable to monitor the safety of wastewater defluoridation equipment and dosing, which is not conducive to reducing the impact of the equipment itself and dosing control on defluoridation efficiency. Furthermore, defluoridation plans cannot be reasonably matched based on processing data, resulting in increased operating costs. Furthermore, the defluoridation status of the wastewater defluoridation process cannot be analyzed, which is not conducive to sufficient contact between the reagent and fluoride ions, and is not conducive to timely replenishment of the reagent.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the Invention

The present invention ensures the defluorination efficiency of the target equipment by analyzing the target equipment itself and the dosing. The defluorination demand matching supervision analysis of the processing data is carried out through information feedback, so as to reasonably match the defluorination plan according to the processing data, avoid resource waste, and reduce operating costs. At the same time, in-depth dosing control supervision feedback analysis is carried out. On the one hand, the stirring interference of the dosing is adjusted to ensure sufficient contact reaction of fluoride ions in the wastewater. On the other hand, the dosage is adjusted to ensure the wastewater defluorination efficiency and the rationality of the automatic addition control of the agent.

BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described below with reference to the accompanying drawings;

[0034] Figure 1 It is a flow chart of the system of the present invention;

[0035] Figure 2 This is a local analysis diagram of Example 1 of the present invention. DETAILED DESCRIPTION

[0036] 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 creative efforts are within the scope of protection of the present invention.

[0037] Example 1:

[0038] See also Figures 1 to 2 As shown, the present invention is a wastewater defluorination control system suitable for a self-crystallizing fluidized bed, comprising a wastewater defluorination platform, an information collection unit, a defluorination status unit, a dosing supervision unit, a treatment matching unit, a tracking supervision unit, and a management response unit. The wastewater defluorination platform is connected to the information collection unit in a one-way communication manner, the information collection unit is connected to the defluorination status unit in a one-way communication manner, the information collection unit is connected to the dosing supervision unit in a two-way communication manner, the defluorination status unit is connected to the treatment matching unit and the tracking supervision unit in a one-way communication manner, the dosing supervision unit is connected to the treatment matching unit in a one-way communication manner, the tracking supervision unit is connected to the management response unit in a one-way communication manner, and the treatment matching unit is connected to the management response unit in a one-way communication manner.

[0039] When the wastewater defluoridation platform generates a supervision instruction, it sends the supervision instruction to the information collection unit. After receiving the supervision instruction, the information collection unit immediately collects and stores the operating condition data and dosing status data of the target equipment. The defluoridation status unit is used to retrieve the operating condition data from the information collection unit and perform defluoridation risk supervision feedback analysis on the operating condition data to determine the impact of the target equipment itself on the wastewater defluoridation efficiency, so as to adjust the target equipment in a timely manner. The specific defluoridation risk supervision feedback analysis process is as follows:

[0040] The wastewater defluoridation period is collected and set as the time threshold. The operating condition data of the target equipment within the time threshold is obtained. The operating condition data includes the operating risk value and the response assessment value. The operating risk value and the response assessment value are compared and analyzed with the preset operating risk value threshold and the preset response assessment value threshold that are stored internally:

[0041] If the operational risk value is less than the preset operational risk value threshold, and the response evaluation value is less than the preset response evaluation value threshold, a stable signal is generated;

[0042] If the operation risk value is greater than or equal to the preset operation risk value threshold, or the response evaluation value is greater than or equal to the preset response evaluation value threshold, a risk signal is generated, and the risk signal is sent to the management response unit through the processing and matching unit. After receiving the risk signal, the management response unit immediately performs the preset early warning operation corresponding to the risk signal, so as to adjust the target equipment in time to reduce the impact of the target equipment itself on the fluoride removal efficiency of wastewater;

[0043] In the implementation of the present invention, the operation risk value represents the portion of the numerical value corresponding to the operating parameter of the target device that deviates from the preset threshold. The operating parameters include the average operating voltage, the average operating power, etc. It should be noted that the operation risk value is an influencing parameter reflecting the operating stability of the target device;

[0044] In the implementation of the present invention, the response evaluation value represents the percentage of the number of times the instruction response time exceeds the preset instruction response time threshold in the total number of times in the history of the target device. The instruction response time represents the time between the instruction reception time and the instruction execution time within the wastewater defluoridation period of the target device. It should be noted that the larger the value of the response evaluation value, the greater the impact on the wastewater defluoridation efficiency.

[0045] The dosing supervision unit is used to retrieve the dosing status data from the information collection unit and perform dosing interference risk assessment on the dosing status data so as to adjust the dosing pump of the target equipment in a timely manner to reduce the impact of the addition of defluorination agents on the defluorination efficiency. The specific dosing interference risk assessment operation process is as follows:

[0046] Obtain the status evaluation value of the dosing pump in the target device within the time threshold. The status evaluation value represents the overlap between the duration corresponding to the operating temperature of the dosing pump exceeding the preset operating temperature threshold and the duration corresponding to the operating amplitude exceeding the preset operating amplitude. Compare and analyze the status evaluation value with the preset status evaluation value threshold stored internally:

[0047] If the ratio between the state evaluation value and the preset state evaluation value threshold is greater than or equal to 1, an alarm signal is generated;

[0048] If the ratio between the status evaluation value and the preset status evaluation value threshold is less than 1, a feedback instruction is generated. When the feedback instruction is generated, the addition deviation value of the defluorination equipment within the time threshold is obtained. The addition deviation value represents the difference between the actual amount of reagent entering and the preset amount of reagent entering. It should be noted that the larger the value of the addition deviation value, the greater the risk of defluorination abnormality. The addition deviation value is compared with the preset addition deviation value threshold stored internally for analysis:

[0049] If the ratio between the added deviation value and the preset added deviation value threshold is less than 1, a normal signal is generated;

[0050] If the ratio between the added deviation value and the preset added deviation value threshold is greater than or equal to 1, an operation and maintenance signal is generated, and the alarm signal or operation and maintenance signal is sent to the management response unit via the information collection unit. After receiving the alarm signal or operation and maintenance signal, the management response unit immediately performs the preset early warning operation corresponding to the alarm signal or operation and maintenance signal, so as to timely adjust the dosing pump of the target equipment to reduce the impact of the addition of defluorination agent on the defluorination efficiency.

[0051] Example 2:

[0052] When stable signals and normal signals are generated, the processing matching unit is used to collect wastewater treatment data and perform defluorination demand matching supervision analysis on the treatment data, so as to reasonably match the defluorination plan according to the treatment data, avoid resource waste, and reduce operating costs. The specific defluorination demand matching supervision analysis process is as follows:

[0053] Collect the wastewater treatment data within the time threshold, including the influent fluoride ion concentration, influent water volume and wastewater pH value, according to the formula R = (JF × a1 + JL × a2 + S × a3) 2 ×a4 to obtain the wastewater status assessment coefficient, wherein JF represents the influent fluoride ion concentration, JL represents the influent water volume, and S represents the wastewater pH value, a1, a2, and a3 are preset proportional factor coefficients for the influent fluoride ion concentration, the influent water volume, and the wastewater pH value, respectively. The proportional factor coefficient is used to correct the deviation of various parameters in the formula calculation process, so as to make the calculation result more accurate, a4 is the preset fault tolerance factor coefficient, a1, a2, a3, and a4 are all greater than zero, R is the wastewater status assessment coefficient, and the wastewater status assessment coefficient R is compared and analyzed with the preset wastewater status assessment coefficient range stored internally, thereby obtaining the defluorination scheme corresponding to the preset treatment matching value range for which the wastewater status assessment coefficient R belongs, and setting the defluorination scheme corresponding to the preset treatment matching value range for which the wastewater status assessment coefficient R belongs as the matching scheme, and sending the matching scheme to the management response unit. After receiving the matching scheme, the management response unit immediately displays the preset warning text corresponding to the matching scheme, so as to perform defluorination operation on the wastewater according to the matching scheme;

[0054] In this way, the defluorination equipment can add different dosages of chemicals to the fluoride-containing wastewater according to different influent fluoride ion concentrations, influent water volume and wastewater pH values, so that the defluorination equipment can add chemicals on demand according to the set defluorination plan, avoiding resource waste and reducing operating costs;

[0055] When stable signals and normal signals are generated, the tracking supervision unit is used to perform dosing control supervision feedback analysis. On the one hand, it adjusts the stirring interference of dosing, and on the other hand, it adjusts the dosing amount. The specific dosing control supervision feedback analysis process is as follows:

[0056] The inlet and outlet fluoride concentrations of the target device within the time threshold are obtained, and the value obtained by subtracting the outlet fluoride concentration from the inlet fluoride concentration is set as the actual treatment concentration value. The actual treatment concentration value is then compared and analyzed with the preset actual treatment concentration value threshold value recorded and stored internally:

[0057] If the actual processing concentration value is greater than or equal to the preset actual processing concentration value threshold, a self-test instruction is generated;

[0058] If the actual treatment concentration value is less than the preset actual treatment concentration value threshold, a feedback signal is generated. When the feedback signal is generated, the dosing period of the target equipment within the time threshold is obtained. The dosing period represents the time length between the start of dosing and the wastewater discharge time. The operating parameters of the stirring component within the dosing period are obtained. The operating parameters include the operation efficiency deviation value and the reaction interference value. The operation efficiency deviation value and the reaction interference value are labeled YP and FG respectively. The contact interference evaluation coefficient is obtained according to the formula C=(YP×f1+FG×f2)×f3, where f1 and f2 are the preset weight factor coefficients of the operation efficiency deviation value and the reaction interference value respectively, and f3 is the preset correction factor coefficient. f1, f2 and f3 are all greater than zero. C is the contact interference evaluation coefficient, and the contact interference evaluation coefficient C is compared and analyzed with the preset contact interference evaluation coefficient threshold stored internally:

[0059] If the ratio between the contact interference evaluation coefficient C and the preset contact interference evaluation coefficient threshold is less than 1, no signal is generated;

[0060] If the ratio between the contact interference evaluation coefficient C and the preset contact interference evaluation coefficient threshold is greater than or equal to 1, an interference signal is generated and sent to the management response unit. After receiving the interference signal, the management response unit immediately performs a preset warning operation corresponding to the interference signal, so as to timely manage the stirring component to ensure sufficient contact reaction of fluoride ions in the wastewater, thereby improving the fluoride removal efficiency of the wastewater;

[0061] In the embodiment of the present invention, the operational efficiency deviation value indicates the time duration during the dosing period when the stirring speed of the stirring component is lower than the preset stirring speed threshold value. It should be noted that the larger the operational efficiency deviation value, the greater the risk of sufficient contact between the reagent and the fluoride ions.

[0062] In the embodiment of the present invention, the reaction interference value represents the portion of the total energy consumption of the stirring component during the dosing period that exceeds the preset total energy consumption value. It should be noted that the larger the value of the reaction interference value, the greater the risk of sufficient contact between the reagent and the fluoride ions.

[0063] When a self-test instruction is generated, the fluoride ion concentration of the outlet water of the target device within the time threshold is obtained, and the target fluoride ion concentration of the outlet water of the target device within the time threshold is obtained. Then, the value obtained by subtracting the fluoride ion concentration of the outlet water from the target fluoride ion concentration is set as the treatment evaluation value, and a discriminant analysis is performed on the treatment evaluation value:

[0064] If the processing evaluation value is greater than or equal to zero, no signal is generated;

[0065] If the treatment evaluation value is less than zero, a drug replenishment signal is generated and sent to the management response unit. After receiving the drug replenishment signal, the management response unit immediately performs the preset warning operation corresponding to the drug replenishment signal to ensure the wastewater defluoridation efficiency and automatic drug addition control;

[0066] In summary, the present invention ensures the fluorine removal efficiency of the target equipment by analyzing from two points: the target equipment itself and the dosing. That is, the defluorination risk supervision feedback analysis is performed on the operating condition data to determine the impact of the target equipment itself on the wastewater defluorination efficiency, so as to adjust the target equipment in time, and perform the dosing interference risk assessment operation on the dosing status data to adjust the dosing pump of the target equipment in time to reduce the impact of the addition of defluorination agents on the defluorination efficiency. The defluorination demand matching supervision analysis is performed on the processing data by means of information feedback, so as to reasonably match the defluorination plan according to the processing data, avoid waste of resources, and reduce operating costs. At the same time, an in-depth dosing control supervision feedback analysis is performed. On the one hand, the stirring interference of the dosing is adjusted to ensure sufficient contact reaction of fluoride ions in the wastewater. On the other hand, the dosage is adjusted to ensure the wastewater defluorination efficiency and the rationality of the automatic addition control of the agent.

[0067] The threshold is set to facilitate comparison. The size of the threshold depends on the amount of sample data and the number of bases set by technicians in this field for each set of sample data; as long as it does not affect the proportional relationship between the parameter and the quantized value.

[0068] The above formulas are obtained by collecting a large amount of data and performing software simulation, and a formula close to the actual value is selected. The coefficients in the formula are set by those skilled in the art according to actual conditions. The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
