[0022] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0023] The technical solution provided by the embodiment of the present application can be applied to various sewage treatment scenarios, in which sewage is first treated and then pollutant detection is performed on the treated sewage. Also, in different sewage treatment scenarios, the results of pollutant detection may have different applications. For example, in some scenarios, the treated sewage can be reused according to the pollutant detection results; in other scenarios, the treated sewage can be discharged according to the pollutant detection results.

[0024] In the embodiment of the present application, the sewage treatment scene may be a sewage treatment scene in a real environment, such as a factory sewage treatment scene, or a sewage treatment scene in a simulated environment, such as an experimental sewage treatment scene.

[0025] In the related art, a fixed detection strategy is usually adopted for the detection of pollutants, which results in the inability to achieve effective and accurate detection of pollutants.

[0026] Based on this, the embodiment of the present application provides a technical solution, which takes into account the impact of sewage treatment strategies on sewage detection, and the sewage detection strategy adapted to the characteristics of sewage, and combines the sewage treatment strategy and the characteristics of sewage to determine the corresponding pollutant detection strategy. Thus, the pollutant detection strategy can achieve effective and accurate pollutant detection of the treated sewage.

[0027] Please refer to Figure 1 An embodiment of the present application provides a pollutant detection system after sewage treatment, and the pollutant detection system includes: a sewage treatment device, a control device and a pollutant detection device.

[0028] In some embodiments, the sewage treatment device may be a hardware device for implementing sewage treatment, such as the following sewage treatment device:

[0029] Buried sewage treatment device: It includes a base and a cylinder assembly. The left side of the cylinder assembly is fixedly connected with a pusher mechanism, the lower end face of the pusher mechanism is fixedly connected to the base, the left side of the upper end face of the cylinder assembly is fixedly connected with a feed pipe, and the upper end face of the feed pipe is fixedly connected with a pretreatment device.

[0031] Industrial wastewater treatment device: a device for treating wastewater generated in the industrial production process. Depending on the characteristics of different industrial wastewater, it may include different treatment units and processes.

[0032] Integrated domestic sewage treatment device: suitable for single family use, the working principle is that the flushing water first passes through the separation tank, and the solid-liquid separation is carried out by the screen. After separation, the feces remain upstream, and are solidified through further treatment, and then manually scooped out for use as organic fertilizer. The liquid with a small amount of feces continues to flow downward and is further intercepted at the outlet of the separation tank to fully remove impurities, and then enters the anaerobic tank for biochemical reaction.

[0033] In addition, there are hospital sewage treatment devices, integrated wastewater treatment devices, etc.

[0034] In an embodiment of the present application, multiple sewage treatment devices can be configured, each sewage treatment device is used to implement a different sewage treatment strategy; or an integrated device integrating multiple sewage treatment devices can be configured so that the integrated device can implement multiple sewage treatment strategies.

[0035] The control device can be communicated with the sewage treatment device and the pollutant detection device respectively; it can transmit data between the two devices, for example: issuing instructions, obtaining processing data and detection data, etc.

[0036] The pollutant detection device may be a hardware device capable of realizing pollutant detection, such as:

[0037] Portable water pollutant detection equipment: can quickly detect COD, ammonia nitrogen, total phosphorus, total nitrogen and other indicators in water, suitable for environmental protection, scientific research institutes, third-party testing, petrochemical, optoelectronic energy, aquaculture, sheet metal electroplating, ink coating, aquaculture, food processing, biopharmaceuticals and engineering and many other industries.

[0038] Water quality analyzer: used to detect various parameters in water quality, such as pH value, dissolved oxygen, turbidity, etc., widely used in water treatment, environmental monitoring and other fields.

[0039] In an embodiment of the present application, multiple pollutant detection devices can be configured, each pollutant detection device is used to execute a different pollutant detection strategy; or an integrated device integrating multiple pollutant detection devices can be configured so that the integrated device can execute multiple pollutant detection strategies.

[0040] In the embodiment of the present application, a variety of pollutant detection devices may be configured. These multiple pollutant detection devices are set at different positions. The treated sewage can be introduced into the corresponding pollutant detection device so that the pollutant detection device can perform pollutant detection.

[0041] Please refer to Figure 2 , the embodiment of the present application provides a flow chart of pollutant detection after sewage treatment, the pollutant detection process includes:

[0042] The sewage treatment device first treats the sewage to obtain treated sewage.

[0043] The control device determines the pollutant detection strategy for the treated sewage and sends the pollutant detection strategy to the pollutant detection device.

[0044] The pollutant detection device performs pollutant detection on the treated sewage according to the pollutant detection strategy issued by the control device, obtains the pollutant detection result, and transmits the pollutant detection result back to the control device.

[0045] Please refer to Figure 3 , the present application embodiment provides a flow chart of a method for detecting pollutants after sewage treatment, the pollutant detection method comprising:

[0046] Step 301 : determining a target pollutant detection strategy type according to a sewage treatment strategy type corresponding to the treated sewage and an influence relationship between a preset sewage treatment strategy type and a pollutant detection strategy type.

[0047] Step 302, determining the target sewage detection strategy evaluation value according to the water quality of the treated sewage, the water volume of the treated sewage, and the discharge standard of the treated sewage.

[0048] Step 303 , determining the target pollutant detection strategy according to the target sewage detection strategy evaluation value, the target pollutant detection strategy type and a preset pollutant detection strategy library.

[0049] Step 304: perform pollutant detection on the treated sewage according to the target pollutant detection strategy to obtain pollutant detection results.

[0050] In this detection process, the sewage treatment process is not included; steps 301 to 303 are steps executed by the control device, and step 304 is a step executed by the pollutant detection device.

[0051] In the embodiments of the present application, regarding the sewage treatment device, how to achieve sewage treatment is not a main scheme of the embodiments of the present application, so reference can be made to the mature technology in the field and no detailed introduction is given here.

[0052] In step 301, the sewage treatment strategy types include: physical type, biological type and chemical type, and the pollutant detection strategy types include: physical type, biological type and chemical type.

[0053] In some embodiments, for the type of wastewater treatment strategy, for example:

[0054] Physical type: Use physical action to separate insoluble substances in sewage without changing the chemical properties during the treatment process. Commonly used methods include gravity separation, centrifugal separation, reverse osmosis, flotation, etc.

[0055] Biological type: Utilize the metabolic function of microorganisms to decompose and oxidize organic matter in the sewage in dissolved or colloidal state into stable inorganic substances, so that the sewage can be purified. Commonly used methods include activated sludge method and biofilm method.

[0056] Chemical type: using chemical reactions to treat or recover dissolved substances or colloidal substances in sewage, mostly used for industrial wastewater. Commonly used methods include coagulation, neutralization, oxidation-reduction, ion exchange, etc.

[0057] In some embodiments, for the type of contaminant detection strategy, for example:

[0058] Chemical type: involves the use of chemical reagents to determine the type and amount of pollutants in wastewater.

[0059] Physical type: using physical means, such as measuring the conductivity, dissolved oxygen, turbidity and other indicators of sewage.

[0060] Biological type: Use biological indicators, such as measuring the content of bacteria, algae, viruses and other biological substances in sewage. In addition, there are infrared spectroscopy analysis, ultrasonic detection, gas chromatography, mass spectrometry and other technologies.

[0061] In the specific detection process, various technical means such as gravimetric analysis, titration analysis, spectrophotometry, atomic absorption spectroscopy, etc. are usually used. Gravimetric analysis is to separate the component to be tested from other components in the sample through physical or chemical reactions, and then determine the content of the component by weighing. Titration analysis is widely used in sewage treatment water quality testing, including acid-base titration, complexometric titration, precipitation titration and redox titration. Spectrophotometry is often used to determine ammonia nitrogen, total nitrogen, cyanide and some metal ions. Atomic absorption spectrometry has fast measurement speed, high sensitivity and accuracy, and is often used to detect various metal ions.

[0062] In addition to the technical means mentioned above, there are also biological types such as microscopy, culture counting, and ELISA, as well as toxicity testing methods such as biological toxicity test and microbial toxicity test. These methods can be used to assess the toxic effects of pollutants in sewage on organisms and comprehensively evaluate the overall environmental quality of sewage.

[0063] It is understandable that some types of sewage treatment strategies may have an impact on other types of pollutant detection strategies. For example, biological sewage treatment strategies may have a certain impact on biological pollutant detection strategies due to the introduction of microorganisms. Generally speaking, if sewage treatment and pollutant detection are separate and independent operating processes, they will not affect each other; however, if sewage treatment and pollutant detection are continuous operating processes, they will affect each other.

[0064] As an optional implementation method, the influence relationship between the preset sewage treatment strategy type and the pollutant detection strategy type includes: if the time interval between the sewage treatment time and the pollutant detection time is greater than or equal to the preset time interval, the physical type of sewage treatment strategy has an influence on the physical type of pollutant detection strategy; if the time interval between the sewage treatment time and the pollutant detection time is less than the preset time interval, the physical type of sewage treatment strategy has an influence on the physical type of pollutant detection strategy, the biological type of pollutant detection strategy and the chemical type of pollutant detection strategy; the biological type of sewage treatment strategy has an influence on the biological type of pollutant detection strategy and the chemical type of pollutant detection strategy; the chemical type of sewage treatment strategy has an influence on the biological type of pollutant detection strategy and the chemical type of pollutant detection strategy.

[0065] In this implementation, if the time interval between the sewage treatment time and the pollutant detection time is greater than or equal to the preset time interval, it means that the impact of the physical type of sewage treatment strategy on the other two types of pollutant detection strategies can be ignored, and only the impact on the physical type of pollutant detection strategy can be considered. Otherwise, it is necessary to consider the impact of the physical type of sewage treatment strategy on the three types of pollutant detection strategies.

[0066] In addition, biological and chemical sewage treatment strategies have an impact on biological and chemical pollutant detection strategies.

[0067] Based on this, step 301 may include: if the sewage treatment strategy type corresponding to the treated sewage is a physical type, determine the time interval between the sewage treatment time and the pollutant detection time; if the time interval is greater than or equal to the preset time interval, determine that the target pollutant detection strategy type is a biological type or a chemical type; if the time interval is less than the preset time interval, determine that the target pollutant detection strategy type is a physical type; if the sewage treatment strategy type corresponding to the treated sewage is a biological type, determine that the target pollutant detection strategy type is a biological type or a physical type; if the sewage treatment strategy type corresponding to the treated sewage is a chemical type, determine that the target pollutant detection strategy type is a chemical type or a physical type.

[0068] In this embodiment, if the sewage treatment strategy type corresponding to the treated sewage is a physical type, the use priority of the physical type pollutant detection strategy is higher than the other two types of pollutant detection strategies.

[0069] If the sewage treatment strategy type corresponding to the treated sewage is biological type or chemical type, the corresponding pollutant detection strategy can use any type of pollutant detection strategy that has no impact.

[0070] In step 302, the water quality and water quantity of the treated sewage may be the results measured by corresponding measuring instruments. The discharge standard of the treated sewage may include: a pollutant content discharge standard and a pollutant type discharge standard. The pollutant content discharge standard may define the maximum pollutant content included in the discharged sewage; the pollutant type discharge standard may define the maximum number of pollutant types included in the discharged sewage.

[0071] The target sewage detection strategy evaluation value is used to characterize the pollutant detection capability of the sewage detection strategy adapted to the treated sewage. The larger the evaluation value is, the stronger the pollutant detection capability of the adapted sewage detection strategy needs to be.

[0072] As an optional implementation, step 302 includes: determining a first sewage detection strategy evaluation value based on the water quality of the treated sewage; determining a second sewage detection strategy evaluation value based on the water volume of the treated sewage; determining a third sewage detection strategy evaluation value based on the discharge standard of the treated sewage; determining a target sewage detection strategy evaluation value based on the first sewage detection strategy evaluation value, the second sewage detection strategy evaluation value and the third sewage detection strategy evaluation value.

[0073] In some embodiments, different evaluation values ​​corresponding to different water qualities (values) are preset, and the first sewage detection strategy evaluation value can be determined according to the current water quality. Also, evaluation values ​​corresponding to different water quantities are preset, and the second sewage detection evaluation value can be determined according to the current water quantity. Also, evaluation values ​​corresponding to different emission standards are preset, and the third sewage detection strategy evaluation value can be determined according to the current emission standard.

[0074] Furthermore, determining the target sewage detection strategy evaluation value according to the first sewage detection strategy evaluation value, the second sewage detection strategy evaluation value and the third sewage detection strategy evaluation value may include: determining the maximum sewage detection strategy evaluation value among the first sewage detection strategy evaluation value, the second sewage detection strategy evaluation value and the third sewage detection strategy evaluation value; if the first sewage detection strategy evaluation value is the maximum sewage detection strategy evaluation value, determining the target sewage detection strategy evaluation value according to the second sewage detection strategy evaluation value and the third sewage detection strategy evaluation value; if the second sewage detection strategy evaluation value is the maximum sewage detection strategy evaluation value, determining the target sewage detection strategy evaluation value according to the first sewage detection strategy evaluation value and the second sewage detection strategy evaluation value; if the third sewage detection strategy evaluation value is the maximum sewage detection strategy evaluation value, determining the third sewage detection strategy evaluation value as the target sewage detection strategy evaluation value.

[0075] In this implementation, the three evaluation values ​​are first compared to determine the maximum sewage detection strategy evaluation value. If the first sewage detection strategy evaluation value is the maximum sewage detection strategy evaluation value, the second sewage detection strategy evaluation value and the third sewage detection strategy evaluation value can be integrated to determine the target sewage detection strategy evaluation value. For example, the smaller value of the second sewage detection strategy evaluation value and the third sewage detection strategy evaluation value can be determined as the target sewage detection strategy evaluation value.

[0076] If the second sewage detection strategy evaluation value is the maximum sewage detection strategy evaluation value, the first sewage detection strategy evaluation value and the second sewage detection strategy evaluation value may be integrated to determine the target sewage detection strategy evaluation value. For example, the larger value of the first sewage detection strategy evaluation value and the second sewage detection strategy evaluation value may be determined as the target sewage detection strategy evaluation value.

[0077] If the third sewage detection strategy evaluation value is the maximum sewage detection strategy evaluation value, the third sewage detection strategy evaluation value may be directly determined as the target sewage detection strategy evaluation value.

[0078] In step 303, the preset pollutant detection strategy library includes: a plurality of pollutant detection strategies corresponding to a plurality of pollutant detection strategy types, each of which is preset with an evaluation value.

[0079] It can be understood that the evaluation value preset by the pollutant detection strategy is used to characterize the pollutant detection capability of the pollutant detection strategy.

[0080] Furthermore, the pollutant detection strategies included in the pollutant detection strategy library are all pollutant detection strategies that can be implemented in relevant scenarios; that is, each pollutant detection strategy is configured with a corresponding pollutant detection device.

[0081] As an optional implementation, step 303 includes: determining multiple pollutant detection strategies corresponding to a target pollutant detection strategy type from multiple pollutant detection strategies corresponding to multiple pollutant detection strategy types; determining multiple pollutant detection strategies that meet the target sewage detection strategy evaluation value from multiple pollutant detection strategies corresponding to the target pollutant detection strategy type; determining the target pollutant detection strategy based on the multiple pollutant detection strategies that meet the target sewage detection strategy evaluation value.

[0082] In this embodiment, multiple pollutant detection strategies corresponding to the target pollutant detection type are first searched, and then multiple pollutant detection strategies that meet the evaluation value are searched from the multiple pollutant detection strategies. Finally, the target pollutant detection strategy is determined based on the pollutant detection strategies that meet the evaluation value.

[0083] In some embodiments, the compliance assessment value may be equal to or close to a target sewage detection strategy assessment value.

[0084] In some embodiments, each pollutant detection strategy is preset with a strategy keyword and a strategy usage count. The strategy keyword can be understood as a keyword used to characterize some characteristics of the strategy, such as separation, penetration, reduction, and decomposition. The strategy usage count can be the strategy usage count determined by statistics of historical pollutant detection data.

[0085] Therefore, determining the target pollutant detection strategy based on multiple pollutant detection strategies that meet the target sewage detection strategy evaluation value can include: determining a first pollutant detection strategy from multiple pollutant detection strategies that meet the target sewage detection strategy evaluation value based on strategy keywords and target strategy keywords, the strategy keywords of the first pollutant detection strategy include the target strategy keywords; determining a second pollutant detection strategy and a third pollutant detection strategy from the first pollutant detection strategy based on the number of times the strategy is used, the number of times the second pollutant detection strategy is used is higher than the number of times other first pollutant detection strategies are used, and the number of times the third pollutant detection strategy is used is lower than the number of times other first pollutant detection strategies are used; determining the second pollutant detection strategy or the third pollutant detection strategy as the target pollutant detection strategy.

[0086] In this embodiment, the target strategy keyword may be a pre-set keyword corresponding to a high-efficiency pollutant detection strategy, that is, the target strategy keyword is a keyword in the high-efficiency pollutant detection strategy.

[0087] In some embodiments, determining the second pollutant detection strategy or the third pollutant detection strategy as the target pollutant detection strategy includes: obtaining the usage status of the pollutant detection device corresponding to the second pollutant detection strategy, and obtaining the usage status of the pollutant detection device corresponding to the third pollutant detection strategy. Further, the pollutant detection strategy corresponding to the unused pollutant detection device is preferentially determined as the target pollutant detection strategy. If both are in use, the pollutant detection strategy corresponding to the pollutant detection device that ended use earlier is preferentially determined as the target pollutant detection strategy. If neither is in use, the pollutant detection strategy corresponding to the pollutant detection device that was last used earlier is preferentially determined as the target pollutant detection strategy.

[0088] Further, in step 304, according to the target pollutant detection strategy, a target pollutant detection device that executes the target pollutant detection strategy is determined; then a control instruction for the target pollutant detection device is generated and sent to the target pollutant detection device, so that the target pollutant detection device performs pollutant detection on the treated sewage and obtains the pollutant detection result.

[0089] In some embodiments, if the treated sewage is located at the target pollutant detection device, the pollutant detection can be performed directly. If the treated sewage is not located at the target pollutant detection device, a control instruction corresponding to the sewage transfer device can also be generated to enable the sewage transfer device to transfer the treated sewage to the corresponding location.

[0090] In the embodiment of the present application, the sewage treatment can be automated in a treatment line, in which the first layer is a sewage treatment device, and the second layer is a pollutant detection device. The pollutant detection devices can be distributed in different locations, and the treated sewage can reach the corresponding pollutant detection device through the corresponding device.

[0091] Furthermore, after obtaining the pollutant detection results, they can be applied.

[0092] As an optional implementation, the pollutant detection method also includes: obtaining the expected sewage treatment results corresponding to the sewage treatment strategy corresponding to the treated sewage, the expected sewage treatment results including: expected residual pollutants, expected residual pollutant content and expected derivative pollutants of the expected residual pollutants, and the expected derivative pollutants correspond to the derivative time compared to the sewage treatment time; determining the expected pollutant detection results based on the expected sewage treatment results; judging whether the expected pollutant detection results are consistent with the expected pollutant detection results; if the expected pollutant detection results are inconsistent with the expected pollutant detection results, re-treating the treated sewage and / or re-detecting pollutants on the treated sewage; if the expected pollutant detection results are consistent with the expected pollutant detection results, marking the treated sewage as treated sewage.

[0093] In some embodiments, the treated sewage can be further discharged for treatment or used for other purposes.

[0094] In some embodiments, the expected sewage treatment result may be the sewage treatment result estimated by the sewage treatment device according to the actual sewage treatment situation. For example, the expected legacy pollutants are estimated and determined based on the pollutants that cannot be covered by the sewage treatment strategy. The expected legacy pollutant content may be one percent of the sewage volume. The expected derivative pollutants of the expected legacy pollutants may be determined based on the preset pollutant derivative relationship and the current expected legacy pollutants. The derivative time corresponding to the expected derivative pollutants compared to the sewage treatment time may be the information included in the preset pollutant derivative relationship.

[0095] The pollutant derived relationship can be a relationship determined based on data in a related pollutant knowledge base; it can also be existing information.

[0096] In some embodiments, the expected pollutant detection results are determined based on the expected sewage treatment results, including: obtaining the detection error corresponding to the target pollutant detection strategy, the detection error including the content detection error and the component detection error; determining the first expected detection pollutant and the first expected detection pollutant content based on the derivation time, sewage treatment time and sewage detection time corresponding to the expected derivative pollutants; determining the second expected detection pollutant based on the expected residual pollutants and the component detection error; determining the second expected detection pollutant content based on the expected residual pollutant content and the content detection error; determining the expected pollutant detection results based on the first expected detection pollutant, the first expected detection pollutant content, the second expected detection pollutant and the second expected detection pollutant content.

[0097] In this embodiment, the detection error corresponding to the target pollutant detection strategy may be an error set when the strategy is formulated.

[0098] In some embodiments, according to the sewage treatment time and the sewage detection time, it can be determined whether the expected derived pollutants have been derived at the sewage detection time. If they have been derived, the first expected detected pollutants include the expected derived pollutants; further, according to the time difference with the sewage detection time, the expected content is determined. For example, the content increases by 0.1 percent per second. If they have not been derived, the first expected detected pollutant may be none and the content may be 0.

[0099] In some embodiments, the expected residual contaminant is reduced or increased according to the component detection error to determine the first expected detected contaminant. The expected residual contaminant content is reduced or increased according to the content detection error to determine the second expected contaminant content.

[0100] Further, the expected pollutant detection result is compared with the expected pollutant detection result. If there is a discrepancy, the treated sewage may be re-treated and / or the treated sewage may be re-tested for pollutants.

[0101] According to the introduction of the embodiment of the present application, it can be seen that the target pollutant detection strategy type that meets the treated sewage is determined by the sewage treatment strategy type corresponding to the treated sewage and the influence relationship between the preset sewage treatment strategy type and the pollutant detection strategy type; then, based on the type, combined with the evaluation value of the pollutant detection capability of the sewage detection strategy adapted to characterize the treated sewage, the target pollutant detection strategy is determined from the multiple pollutant detection strategies corresponding to the preset multiple pollutant detection strategy types, so as to perform pollutant detection based on the target pollutant detection strategy. Since the influence of the sewage treatment strategy on sewage detection is taken into account, and the sewage detection strategy adapted to the characteristics of the sewage is taken into account, the target pollutant detection strategy finally determined can achieve effective and accurate pollutant detection of the treated sewage.
