Abstract

The present invention belongs to the technical field of sewage treatment, and specifically discloses an artificial intelligence-based sewage treatment management system for production of impregnated paper. By setting sewage discharge channels and treatment pools in each production process area of ​​an impregnated paper production line, sewage water quality detection and sewage water quality similarity identification are performed when sewage is generated in each production process. When homogeneous production processes are identified, sewage discharged from the upstream process flows into the treatment pool of the downstream process for combined treatment, thereby realizing single treatment of sewage in the production process of impregnated paper.

On the other hand, since sewage with similar water quality can be treated with the same agent, the types and amounts of agents are reduced, thereby reducing the treatment cost. On the other hand, the combined treatment of sewage with similar water quality can maintain the consistency of treatment conditions and improve the stability of the treatment effect.

Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and specifically discloses an artificial intelligence-based impregnated paper production sewage treatment management system. Background Art

[0002] Impregnated paper is a specially treated paper widely used in furniture manufacturing, decorative materials and other occasions that require wear resistance, waterproof and chemical resistance. Similar to the production of ordinary paper, the production process of impregnated paper also requires a large amount of water resources, resulting in a certain amount of wastewater generated in almost every production process, resulting in a high demand for wastewater treatment.

[0003] For example, the Chinese invention patent with publication number CN104628176A records a water treatment system, including a sewage storage tank, a sewage treatment tank, a clean water tank, a sediment storage tank and a blower; the sewage storage tank is provided with a sewage pipe connected to the production workshop and connected to the sewage treatment tank; the clean water tank and the sediment storage tank are respectively arranged on both sides of the sewage treatment tank; the blower is arranged on one side of the clean water tank. This scheme uses the sewage pipe to uniformly store the sewage generated by the papermaking production workshop in the sewage storage tank for sewage treatment. Although this treatment method can centrally treat wastewater, it also has some obvious defects, especially ignoring the similarity of sewage quality between different production processes, and some processes in the production of impregnated paper may use similar chemicals or processes. The conditions result in the sewage produced by these processes having similar water quality characteristics. If the sewage produced by each production process is mixed for treatment, it is easy to lead to dilution or masking of the concentration of certain pollutants, making it difficult to treat pollutants that could have been efficiently treated individually, thus reducing the treatment efficiency. In addition, due to the wide variety of pollutants involved in the sewage treatment pool, different types of pollutants need to be treated with different chemical agents, which requires the use of multiple agents, which invisibly increases the cost of the agents. At the same time, there may be compatibility issues between different agents. Some agents may affect each other when mixed, reducing the treatment effect or even producing new by-products, increasing the difficulty of treatment. Furthermore, the water quality parameters of sewage from different processes fluctuate greatly after being mixed, which may lead to unstable treatment effects. Summary of the invention

[0004] In view of the shortcomings of the prior art mentioned above, the purpose of the present invention is to provide an artificial intelligence-based impregnated paper production wastewater treatment management system, which utilizes the similarity of wastewater quality generated in different production processes in the production of impregnated paper to perform wastewater quality detection and wastewater quality similarity identification in different production processes during the production process, thereby merging wastewater from homogeneous production processes for treatment, effectively making up for the problems mentioned in the background technology.

[0005] The purpose of the present invention can be achieved through the following technical solutions: an artificial intelligence-based impregnated paper production wastewater treatment management system, comprising: a wastewater treatment equipment setting module, which is used to set a sewage discharge channel and a treatment pool in each production process area of ​​the impregnated paper production line, the treatment pool is provided with a connecting pipe, and the sewage discharge channel is divided into an initial section, a middle section and a terminal section, wherein the initial section and the terminal section are both equipped with a control valve, the middle section is provided with a water body sensing terminal, a water quality detection terminal and a flow meter, and the terminal section is equipped with two control valves, one is marked as a direct control valve connected to the treatment pool, and the other is marked as an associated control valve connected to the treatment pool of the subsequent production process.

[0006] The sewage discharge monitoring module is used to synchronously open the initial control valve and the middle water body sensing terminal of the sewage discharge channel corresponding to each production process when starting the production line. When sewage is generated, the sewage flows into the middle section through the initial section of the sewage discharge channel and is sensed by the water body sensing terminal. When the water body is sensed, the water quality detection terminal is started to detect the sewage water quality parameters.

[0007] The sewage water quality similarity identification module is used to compare the sewage water quality parameters detected in each production process with the sewage water quality parameters detected in the subsequent production process, and identify whether there is a homogeneous production process group. If so, the previous production process in the homogeneous production process group is recorded as the upstream process, and the subsequent production process is recorded as the downstream process.

[0008] The sewage discharge control module is used to open the associated control valve at the end of the sewage discharge channel corresponding to the upstream process and the control valve of the connecting pipe of the downstream process treatment tank so that the sewage discharged from the upstream process flows into the treatment tank of the downstream process, and at the same time open the direct control valve at the end of the sewage discharge channel of the downstream process and adjust the opening of the control valve.

[0009] The sewage treatment module is used to treat sewage in the treatment tank of the downstream process based on the sewage water quality parameters of the homogeneous production process group.

[0010] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention sets sewage discharge channels and treatment tanks in each production process area of ​​the impregnated paper production line, thereby performing sewage quality detection and sewage quality similarity identification when sewage is generated in each production process. When homogeneous production processes are identified, the sewage discharged from the upstream process flows into the treatment tank of the downstream process for combined treatment, thereby realizing the single treatment of sewage in the impregnated paper production process. On the one hand, the complexity of the sewage treatment process is greatly reduced, which is conducive to improving the treatment efficiency. On the other hand, since sewage with similar water quality can be treated with the same chemical, the types and amounts of chemicals are reduced, thereby reducing the treatment cost. On the other hand, the combined treatment of sewage with similar water quality can maintain the consistency of treatment conditions and improve the stability of the treatment effect.

[0011] (2) When treating wastewater generated by homogeneous production processes, the present invention sequentially treats wastewater by utilizing treatment processes corresponding to various wastewater water quality parameters, thereby achieving reasonable and efficient wastewater treatment, reducing unnecessary treatment steps, and thus reducing treatment costs. In addition, sequential treatment can protect equipment and avoid equipment damage caused by improper early treatment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0018] The present invention proposes an artificial intelligence-based impregnated paper production wastewater treatment management system, which includes the following modules: a wastewater treatment equipment setting module, a wastewater discharge monitoring module, a wastewater water quality similarity identification module, a wastewater discharge control module and a wastewater treatment module.

[0019] See also Figure 1As shown, the sewage treatment equipment setting module is connected to the sewage discharge monitoring module, the sewage discharge monitoring module is connected to the sewage water quality similarity identification module, the sewage water quality similarity identification module is connected to the sewage discharge control module, and the sewage discharge control module is connected to the sewage treatment module.

[0020] The sewage treatment equipment setting module is used to set up sewage channels and treatment pools in each production process area of ​​the impregnated paper production line. The treatment pool is provided with a connecting pipe equipped with a control valve. The sewage channel is divided into an initial section, a middle section and a terminal section. The initial section and the terminal section are both equipped with control valves. The middle section is provided with a water body sensing terminal, a water quality detection terminal and a flow meter. The terminal section is equipped with two control valves, one of which is marked as a direct control valve connected to the treatment pool, and the other is marked as an associated control valve connected to the treatment pool of the subsequent production process.

[0021] Applied to the above scheme, in order to enable the sewage generated during each production process to flow directly through the sewage pipe, a local collection tank or a sump can be set near each production process area to temporarily collect the sewage generated by the process, thereby connecting the sewage pipe to the local collection tank or sump.

[0022] Further applied to the above scheme, the sewage channel set up in each production process also includes a length setting. Specifically, the length of the sewage channel of each production process should be set according to the inverse pyramid gradient according to the sequence of the production processes. That is, the sewage channel length of the initial process is the longest, providing sufficient space to accommodate the sewage generated in the initial stage, and as the process progresses, the length of the discharge pipe of the subsequent process gradually decreases, reflecting the delayed effect of sewage generation as the production process progresses.

[0023] The first point of the length layout of the above-mentioned sewage channel is that the sewage generated by the initial process is earlier, while the sewage generated by the subsequent process is later, so a certain time window needs to be given to sewage quality detection and similarity identification. If the sewage channel lengths of all processes are the same, it is easy to cause the sewage generated by the initial process to accumulate during the detection and identification period, which will lead to the discharge spraying phenomenon caused by sewage accumulation when the homogeneous production process is identified for combined discharge. By setting the length of the sewage channel in a gradient, such problems can be effectively avoided to ensure that the sewage is discharged and treated smoothly and orderly; the second point is that in order to ensure that the combined discharge can be achieved when the homogeneous production process is identified, the sewage channel of each production process must be connected to the treatment pool of the subsequent production process. If the sewage channel lengths of all processes are the same, the treatment pools of each production process will be at the same level. Under this layout, when the sewage channel is connected to the treatment pool of the subsequent production process, the connecting pipe is usually inclined rather than vertical. In the inclined state, the power of the water flow may be restricted. Compared with the vertical connection, the inclined connecting pipe may affect the discharge of sewage from the upstream process to the downstream process, resulting in poor discharge or uneven flow rate, which in turn affects the efficiency and effectiveness of sewage treatment.

[0024] Further applied to the above scheme, the specific operation of dividing the sewage channel into the initial section, the middle section and the final section is to equally divide the length of the sewage channel of each production process into three sections, namely the initial section, the middle section and the final section. The initial section is connected to a local collection tank or a water collection well to collect sewage generated by each production process. The middle section is equipped with a water body sensing terminal, a water quality detection terminal and a flow meter. The final section is connected to the treatment tank. The reason for setting the corresponding detection terminal in the middle section is that the sewage in the initial section has just been discharged from the production process, and the water quality may be unstable and have large fluctuations. Testing at this time may not accurately reflect the actual situation of the sewage. After the sewage flows through the initial section and enters the middle section, the water quality is initially stable, making the water quality data more representative.

[0025] In the example of the above scheme, the water body sensing terminal can be a water level sensor or a liquid level sensor. This type of sensor is mainly used to detect the existence of water bodies and their horizontal position. The water quality detection terminal is used to detect the water quality of sewage. Since the water quality detection terminal needs to be placed in the sewage channel, its size needs to be small and can adapt to the narrow sewage channel space. It has good waterproof performance and can work for a long time in the sewage environment; at the same time, it can simultaneously detect multiple water quality parameters, such as pH value, conductivity, dissolved oxygen, turbidity, COD, BOD, etc.; and it has the ability of continuous monitoring to ensure the timeliness and reliability of the data. The water body sensing terminal is wirelessly connected to the water quality detection terminal in a one-way manner, and the flow meter is used to detect the flow rate of sewage in the sewage channel.

[0026] Further applied to the above scheme, the control valve configured at the beginning of the sewage channel can be in a closed state when the production line is not started, which can prevent unplanned sewage discharge due to misoperation or other reasons, and reduce sewage corrosion on the pipeline, extending the service life of the pipeline. More importantly, the system can be isolated when the production line is not started to ensure that it will not be disturbed during maintenance. The terminal section of the sewage channel is equipped with two control valves, one is marked as a direct control valve connected to the treatment tank, and the other is marked as an associated control valve connected to the treatment tank of the subsequent production process. Since there is more than one subsequent production process, multiple associated control valves need to be equipped, and each associated control valve is connected to the treatment tank of a single subsequent production process.

[0027] Further applied to the above scheme, since there is a certain space interval between the associated control valve configured at the terminal of the sewage pipe and the subsequent treatment pool, in order to realize the connection between the sewage channel of the previous production process and the treatment pool of the later production process, a connecting pipe is provided in the treatment pool of each production process to connect with the associated control valve equipped at the terminal of the sewage channel of the previous production process. In view of the fact that each production process may correspond to multiple previous production processes, there are more than one connecting pipes set inside the treatment pool, and each connecting pipe corresponds to the corresponding previous production process one by one. Through this design, it can be ensured that the sewage generated by the previous production process can be effectively transmitted to the treatment pool of the later production process, and the controllability and stability of the transmission process can be guaranteed through the setting of the control valve and the connecting pipe.

[0028] In the improved implementation of the above scheme, no connecting pipe is provided in the treatment tank of the initial production process. This is because the initial production process, as the first process of impregnated paper production, does not have any previous production process, and there is no need to connect the associated control valve equipped at the terminal of the sewage discharge channel of the previous production process. However, due to the existence of a prerequisite production process in the treatment tank of the subsequent production process, a connecting pipe is required in the treatment tank of the subsequent production process.

[0029] It should be understood that when conducting combined sewage discharge treatment, the sewage discharge channel of each production process is directly connected to the treatment pool of the subsequent production process, rather than connecting the sewage discharge channel to the sewage discharge channel of the subsequent production process, mainly because the amount of sewage that the sewage discharge channel can accommodate is limited. Specifically, when combined discharge, not only the sewage generated by this process must enter the treatment pool through the sewage discharge channel, but if the sewage generated by the previous production process with similar water quality as this process also enters the treatment pool through the same sewage discharge channel, it is very likely to cause blockage or overflow of the sewage discharge channel. By adopting the design of directly connecting the sewage discharge channel of each production process with the treatment pool of the subsequent production process, the sewage generated by the previous production process can be directly discharged into the treatment pool to avoid the above problems and ensure that the sewage can enter the treatment pool smoothly.

[0030] Further applied to the above scheme, the treatment pool connected to the sewage discharge channel of each production process is not only used to store the sewage generated by this process, but also used to store the sewage generated by the previous production process with similar water quality characteristics to this process. It is also a place for sewage treatment.

[0031] The above sewage treatment equipment is set up in Figure 2 shown.

[0032] The sewage discharge monitoring module is used to synchronously open the starting control valve and the middle water body sensing terminal of the sewage discharge channel corresponding to each production process when starting the production line. When sewage is generated, the sewage flows into the middle section through the starting section of the sewage discharge channel and water body sensing is performed using the water body sensing terminal. When the water body is sensed, the water quality detection terminal is triggered to perform sewage water quality parameter detection. When the water body is not sensed, the water quality detection terminal is not triggered.

[0033] From the above, we can see that there is a trigger relationship between the water body sensing terminal and the water quality detection terminal. For the specific trigger relationship process, see Figure 3 shown.

[0034] It needs to be explained that when sewage appears in the sewage channel, it is first sensed by the water body sensing terminal, and when the water body is sensed, the water quality detection terminal is triggered to perform water quality detection. This can reduce the ineffective operation time of the water quality detection terminal when there is no water body, avoid meaningless energy consumption, and help extend its service life. In addition, detection is only performed when there is sewage, ensuring that each test is carried out under real conditions, thereby improving the accuracy of the test results.

[0035] In the preferred implementation of the above scheme, the sewage water quality parameters are detected as follows: when the water body is sensed, the water quality detection terminal is triggered to collect the sewage water quality parameters according to the set collection time to obtain the sewage water quality parameter time series.

[0036] As an example, sewage water quality parameters include but are not limited to pH value, conductivity, dissolved oxygen, turbidity, COD, BOD, etc.

[0037] It should be noted that in the production process of impregnated paper, the time series of sewage water quality parameters is formed when the sewage water quality parameters are tested in order to obtain the dynamic state of sewage water quality changing over time and analyze relatively stable water quality parameters. Through the continuous monitoring of time series data, we can fully understand the changing trend of water quality and identify stable water quality parameters, providing reliable data support for subsequent sewage water quality similarity identification. If only the sewage water quality parameters at a single moment are tested, due to the instability of the water quality itself, it is easy for the test results to be affected by instantaneous fluctuations, resulting in detection errors.

[0038] The sewage water quality similarity identification module is used to compare the sewage water quality parameters detected in each production process with the sewage water quality parameters detected in the subsequent production process, and identify whether there is a homogeneous production process group. If so, the previous production process in the homogeneous production process group is recorded as the upstream process, and the subsequent production process is recorded as the downstream process.

[0039] In the manner in which the above scheme can be implemented, the identification of whether there is a homogeneous production process group refers to the following process: extract the effective value of each sewage water quality parameter corresponding to the corresponding production process from the sewage water quality parameter time series corresponding to each production process, and the specific extraction operation is as follows: extract the maximum and minimum values ​​of each sewage water quality parameter in each production process from the sewage water quality parameter time series corresponding to each production process, and calculate the stability of each sewage water quality parameter in each production process, where the stability calculation formula is , where , They respectively represent the maximum and minimum values ​​of the sewage water quality parameters, and are compared with the set effective threshold value. For example, the effective threshold value is 0.8. If the stability of a sewage water quality parameter in a production process reaches the effective threshold value, it indicates that the parameter has changed little during this period and has high predictability and representativeness. In this case, taking the mean in the time series as the effective value can reflect the true average level of the parameter and reduce the impact of random fluctuations. At this time, the mean of the sewage water quality parameter in the time series of the sewage water quality parameters corresponding to the production process is taken as the effective value of the sewage water quality parameter corresponding to the production process. Otherwise, it indicates that the parameter has changed greatly during this period and there is a significant fluctuation. At this time, selecting the sewage water quality parameter value corresponding to the closest time in the time series can reflect the latest status of the current water quality. At this time, the sewage water quality parameter in the time series of the sewage water quality parameters corresponding to the production process at the closest time to the current time is taken as the effective value of the sewage water quality parameter corresponding to the production process.

[0040] Each production process is compared with the subsequent production processes in the order of the production processes to form several comparison groups.

[0041] In the example of the above scheme, assuming that the production processes of the impregnated paper are A, B, C, and D in order, each production process is compared with the subsequent production process to form comparison groups of A and B, A and C, A and D, B and C, B and D, and C and D.

[0042] The effective values ​​of each sewage water quality parameter in the two production processes in each comparison group are subtracted to obtain the comparison difference of each sewage water quality parameter, and the absolute value is taken and divided by the sewage water quality parameter of the previous production process in the comparison group to obtain the difference degree of each sewage water quality parameter in each comparison group.

[0043] The comprehensive difference of sewage water quality parameters corresponding to each comparison group was obtained by weighted averaging the difference of each sewage water quality parameter in each comparison group.

[0044] The comprehensive difference of sewage water quality parameters corresponding to each comparison group is compared with the preset critical difference. The purpose of setting the critical difference is to assist in the screening of alternative similar groups. If the comprehensive difference of sewage water quality parameters corresponding to a comparison group is less than the critical difference, it means that the sewage water quality parameters of the comparison group are relatively similar. In this case, the comparison group will be used as an alternative similar group, and the front production process in the group will be used as the target process of the alternative similar group.

[0045] The target processes of each alternative similarity group are compared, and the alternative similarity groups corresponding to the same target process are extracted and classified to form a set of alternative similarity groups corresponding to the same target production process, and the formed set of alternative similarity groups is numbered.

[0046] In the example of the above scheme, assume that the screened alternative similarity groups are A and B, A and C, B and D, and C and D. At this time, the target processes of each alternative similarity group are A, A, B, and C, respectively, and the alternative similarity groups corresponding to the same target process are A and B, and A and C.

[0047] The alternative similar group sets are extracted in sequence according to the set number sequence, and the production processes except the target process in each alternative similar group in the set are arranged in the order of production processes, and then the production process ranked first and the target process are extracted to form a homogeneous production process group. At the same time, the sets of processes that have been included in the homogeneous production process group are eliminated from other alternative similar group sets.

[0048] In the example provided above, the production processes other than the target process in the candidate similarity group set are B and C, among which B is ranked first, so the homogeneous production process group formed is A and B, and the other candidate similarity groups are A and C, but A has formed a homogeneous production process group, so the candidate similarity group of A and C is eliminated. This ensures that the production processes already included in the homogeneous production process group will not be double-counted.

[0049] The alternative similar groups other than those eliminated are logically grouped together to identify homogeneous production process groups.

[0050] It should be understood that when conducting the combined discharge of wastewater from homogeneous production processes, the wastewater from the upstream production process is usually discharged into the homogeneous downstream production process, rather than the downstream to the upstream. The reason is that the downstream process usually has a stronger treatment capacity and a higher treatment load, and can withstand the wastewater generated by the upstream process. On the contrary, if the wastewater from the downstream process is returned to the upstream process, it may exceed the treatment capacity of the upstream process. In addition, the production process is generally designed according to the forward flow, that is, from raw material processing to finished product production. Wastewater discharge also follows this order, flowing from the upstream process to the downstream process, which conforms to the natural order of the process flow. If the reverse flow increases the complexity of the process flow, it may cause additional operational difficulties and technical challenges.

[0051] It is further explained that when there are alternative similar groups such as A and B, A and C, it means that the sewage water quality of processes A, B and C is similar. At this time, A and B are selected as homogeneous production process groups in consideration of the distance of the discharge pipeline, where the discharge pipeline between A and B is definitely shorter than the discharge pipeline between A and C. A shorter pipeline means less energy is required to pump sewage when a pump is needed as a discharge power source. Pumping sewage consumes electricity. The longer the pipeline, the longer the pumping distance, and the higher the energy consumption. Choosing a shorter pipeline can reduce energy consumption and reduce operating costs. At the same time, a longer pipeline increases the chance of failure, such as blockage, leakage and other problems. Shorter pipelines reduce these failure points and improve the reliability of discharge.

[0052] What needs to be further explained is that when there are alternative similar groups such as A and B, A and C, it means that the sewage water quality parameters of A, B and C are relatively similar. The reason for not discharging A and B into C at the same time is that the treatment capacity of process C may be limited. If the sewage of A and B is discharged into process C at the same time, it may exceed the treatment capacity of process C, resulting in incomplete treatment or overload of treatment facilities. In addition, although the sewage of A and B is similar, the water quality after the merger may change, making process C difficult to treat. For example, when two similar sewages are mixed, new chemical reactions may occur to form by-products that are difficult to treat.

[0053] The sewage discharge control module is used to open the associated control valve at the end of the sewage discharge channel corresponding to the upstream process and the control valve of the connecting pipe of the downstream process treatment tank to allow the sewage discharged from the upstream process to flow into the treatment tank of the downstream process, and at the same time open the direct control valve at the end of the sewage discharge channel of the downstream process, and adjust the opening of the control valve. The specific adjustment process is: use a flow meter to collect the sewage flow rate of the sewage discharge channels corresponding to the upstream process and the downstream process in real time.

[0054] Compare the collected sewage flow rates of the sewage channels corresponding to the upstream and downstream processes with the limited sewage flow rates. If the sewage flow rates of the sewage channels corresponding to the upstream and downstream processes do not reach the limited sewage flow rates, where the limited sewage flow rate is the maximum sewage flow rate that the sewage channel can reach, which can be obtained from the instructions for use according to the size specifications of the sewage channel, then adjust the control valves of the upstream and downstream processes to their maximum openings. This adjustment is intended to prevent sedimentation or other problems caused by too low flow rates. Otherwise, substitute them into the regulation model. , and obtain the adjustment results of the control valves corresponding to the upstream and downstream processes It should be added that the control valve of the upstream process is the associated control valve connecting the terminal section of the upstream process sewage channel with the downstream process treatment pool, and the control valve of the downstream process is the direct control valve of the downstream process sewage channel. , They represent the sewage flow rates of the upstream and downstream processes in the corresponding sewage channels, Indicates the limited sewage flow rate, Indicates and.

[0055] It should be explained that when one of the sewage flow rates of the upstream and downstream processes is greater than the specified sewage flow rate and the other is less than the specified sewage flow rate, the control valve needs to be adjusted accordingly, that is, the control valve in the process with a flow rate greater than the specified flow rate is kept at the maximum opening, and the control valve in the process with a flow rate less than the specified sewage flow rate is reduced. This can maintain the maximum opening of the control valve in the process with a flow rate greater than the specified sewage flow rate, allowing excessive sewage to pass smoothly and prevent sewage from being accumulated in the upstream process; reducing the opening of the control valve in the process with a flow rate less than the specified sewage flow rate can avoid excessive sewage from flowing into the treatment pool at the same time when both are kept at the maximum opening, causing a greater impact on the treatment pool. Among them, reducing the opening is a reduction relative to the maximum opening.

[0056] What needs to be further explained is that when the sewage flow rates upstream and downstream reach the limited sewage flow rates, in order to avoid maintaining the maximum opening at the same time and causing impact on the treatment pool, the opening of the upstream and downstream control valves can be gradually reduced synchronously. For example, first reduce it by 5%, and observe the flow rate change. If the flow rate is still large, it can be reduced by another 5%. Such a gradual reduction in flow rate can avoid sewage backlog caused by a sudden and drastic reduction in opening. At the same time, because the reduction is small each time, the flow rate gradually decreases, and will not cause a sudden high load on the treatment pool.

[0057] The sewage treatment module is used to treat sewage in the treatment tank of the downstream process based on the sewage water quality parameters of the homogeneous production process group. The specific processing is as follows: the treatment processes corresponding to each sewage water quality parameter in the homogeneous production process group are obtained respectively.

[0058] In the example of the above scheme, the treatment processes corresponding to pH value, conductivity, dissolved oxygen, turbidity, COD, and BOD are pH value adjustment, conductivity control, dissolved oxygen adjustment, turbidity control, and organic matter removal, respectively.

[0059] Based on the treatment processes corresponding to various sewage water quality parameters, the treatment sequence of various sewage water quality parameters is obtained from the preset treatment process sequence following principle, and then the sewage is treated according to the treatment sequence.

[0060] Preferably, the treatment process sequence follows the principle of 1. pH adjustment, 2. turbidity control, 3. conductivity control, 4. dissolved oxygen adjustment, 5. organic matter removal, where pH is a prerequisite for many treatment processes. For example, biological treatment also requires a specific pH range. Chemical reaction: Many chemical reactions (such as oxidation, reduction, etc.) need to be carried out within a specific pH range, otherwise the reaction efficiency will be greatly reduced. Therefore, it is necessary to adjust the pH value first to ensure the smooth progress of subsequent processes. Turbidity control is usually carried out through pretreatment methods such as coagulation and flocculation. These methods need to be carried out after pH adjustment, because pH value affects the effect of coagulants. High turbidity indicates that there are more suspended particles in the water, which will interfere with subsequent treatment processes, so turbidity control ranks second. High conductivity means that there are more soluble solids in the water. Removal of soluble solids is usually carried out through technologies such as reverse osmosis. These technologies need to be carried out after turbidity control because suspended matter can damage reverse osmosis membranes. Dissolved oxygen adjustment is usually placed before organic matter removal because dissolved oxygen is required for biological treatment of organic matter. COD and BOD are important indicators for measuring organic matter content. Organic matter removal is usually placed after the previous steps because the previous steps have created favorable conditions for the removal of organic matter.

[0061] The above principles for the order of treatment processes are based on the interdependence between different water quality parameters.

[0062] The present invention treats the sewage generated by homogeneous production processes by utilizing the treatment processes corresponding to various sewage water quality parameters to sequentially treat the sewage, thereby achieving reasonable and efficient sewage treatment, reducing unnecessary treatment steps, and thus reducing treatment costs. In addition, treating in sequence can protect equipment and avoid equipment damage caused by improper preliminary treatment.

[0063] The above contents are merely examples and explanations of the concept of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they should all fall within the protection scope of the present invention.

When the water body is sensed, the water quality detection terminal is triggered to perform sewage water quality parameter detection; The sewage water quality similarity identification module is used to compare the sewage water quality parameters detected in each production process with the sewage water quality parameters detected in the subsequent production process, and identify whether there is a homogeneous production process group.

If there is a comparison group whose comprehensive difference of sewage water quality parameters is less than the critical difference, then the comparison group is used as an alternative similarity group, and the front production process in the group is used as the target process of the alternative similarity group; Compare the target processes of each candidate similarity group, extract the candidate similarity groups corresponding to the same target process, classify them to form a set of candidate similarity groups corresponding to the same target production process, and number the formed set of candidate similarity groups; Extract candidate similarity group sets in sequence according to the set number sequence, and arrange the production processes except the target process in each candidate similarity group in the set in the order of production processes, and then extract the production process ranked first and the target process to form a homogeneous production process group, and at the same time, remove the process sets that have been used as homogeneous production process groups from other candidate similarity group sets; The alternative similar groups other than those eliminated are logically grouped together to identify homogeneous production process groups.
