[0025] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0026] In this embodiment, a leachate treatment effect evaluation method is provided, which is applied to a leachate treatment system. The leachate treatment system includes a plurality of sub-process systems. The sub-process systems include an adjustment tank treatment system, an anaerobic treatment system, a primary biochemical treatment system, and a secondary biochemical treatment system. As Figure 1 shown, the method includes:

[0027] Step 101: Obtain the performance data of each sub-process system in the leachate treatment system when treating the target treated leachate during a preset evaluation period. The performance data includes the water quality index value of the target treated leachate after being treated, the initial pollutant concentration of the target treated leachate before being treated, the final pollutant concentration of the target treated leachate after being treated, and the actual treated water volume during the process of the sub-process system treating the target treated leachate. The water quality index value includes at least one of biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, and total organic carbon.

[0028] Leachate produced by domestic garbage is a high-concentration organic wastewater with complex pollutant components, including a variety of toxic and harmful substances, including dissolved organic matter, inorganic salt components, heavy metals, etc., and the water quality and quantity vary greatly. According to the environmental discharge requirements, the leachate treatment process generally adopts the "biochemical + physical" treatment process, that is, the process route of "pretreatment + anaerobic + aerobic + MBR (Membrane Bio-Reactor) + nanofiltration + reverse osmosis", which can meet the requirements of leachate effluent discharge. The leachate treatment process adopts biochemical and physical treatment methods. It is a multivariate, highly correlated, non-steady-state nonlinear system that integrates uncertain factors such as microbial reactions, water quality, water quantity and environment, and has a large inertial time lag. Although the deep treatment system (membrane system) has a high degree of automation, stable effect and controllable energy consumption. However, it is difficult to mathematically model the biochemical treatment process and it is difficult to use strict mathematical methods for quantitative description. The degree of automation is low, the control difficulty is high, and the stability of the treatment effect is not good. At present, in the domestic leachate treatment system, the operating data between and within the subsystems are strongly correlated and nonlinear. The pollutant concentration in the leachate is high and the composition is complex. The water quality detection instrument is expensive and the maintenance workload is large, and a large amount of manual testing of water quality indicators is required. Most operations are manual, and the treatment effect depends largely on the experience and technical level of the operators. Therefore, regular evaluation of the system treatment status and effect, and then targeted improvement measures can improve the treatment effect of the leachate treatment system.

[0029] In the above embodiments of the present application, an evaluation period can be set in advance, such as half a year, a year or other time, so that the treatment effect of the leachate treatment system within the preset evaluation period can be evaluated. Specifically, the performance data of each sub-process system in the leachate treatment system when processing the target treatment leachate within the preset evaluation period is obtained. The performance data include the water quality index value of the target treatment leachate after treatment, the initial concentration of pollutants in the target treatment leachate before treatment, the final concentration of pollutants in the target treatment leachate after treatment, and the actual treatment water volume in the process of the sub-process system processing the target treatment leachate. The water quality index value includes at least one of biochemical oxygen demand, chemical oxygen demand, dissolved oxygen and total organic carbon, so as to subsequently calculate various performance index values ​​to be evaluated.

[0030] Step 102, based on the performance data of any sub-process system, obtain the performance indicator value to be evaluated of the sub-process system on each performance indicator, wherein the performance indicator includes water quality indicator, pollutant removal rate and water output efficiency.

[0031] Next, based on the performance data, the performance indicator values ​​to be evaluated for each sub-process system are obtained respectively. The performance indicators include water quality, pollutant removal rate and water output efficiency, in preparation for further evaluation.

[0032] Step 103: Based on the performance index value to be evaluated of any sub-process system and the preset performance judgment threshold of the performance index corresponding to the performance index value to be evaluated, obtain the evaluation result of the sub-system treatment effect of the sub-process system within the preset evaluation period. Based on the evaluation results of the sub-system treatment effects of each sub-process system, obtain the comprehensive evaluation result of the treatment effect of the leachate treatment system within the preset evaluation period.

[0033] Next, based on the performance index value to be evaluated of any sub-process system and the preset performance judgment threshold of the performance index corresponding to the performance index value to be evaluated, obtain the evaluation result of the sub-system treatment effect of the sub-process system within the preset evaluation period. Based on the evaluation results of the sub-system treatment effects of each sub-process system, obtain the comprehensive evaluation result of the treatment effect of the leachate treatment system within the preset evaluation period.

[0034] By applying the technical solution of this embodiment, by obtaining the performance data (including water quality index values, initial and final pollutant concentrations, actual treated water volume, etc.) of each sub-process system in the leachate treatment system when treating the target treated leachate within the preset evaluation period, it can provide detailed basis for system optimization. Performance indexes such as water quality indexes, pollutant removal rates, and effluent efficiency calculated based on the performance data help to refine the analysis of the specific performance of each sub-process system and identify the strengths and weaknesses in the treatment process. Combining the performance index values and their corresponding preset performance judgment thresholds, the evaluation results of the treatment effects of each sub-process system within the preset evaluation period can be obtained. The obtained evaluation results of the treatment effects can provide strong support for the subsequent optimization and upgrade of the leachate treatment system, helping to improve the treatment efficiency, reduce the operating cost, and achieve a win-win situation of environmental and economic benefits.

[0035] Optionally, the leachate treatment system corresponds to an influent working condition library, and the influent working condition library is used to set the operating parameters of the treatment equipment in each sub-process treatment system; after step 103, based on the evaluation results of the treatment effects of each sub-process system, obtain the comprehensive evaluation result of the treatment effect of the leachate treatment system within the preset evaluation period, and then refer to Figure 2 As shown, it specifically includes:

[0036] Step 201: According to the performance indexes shown as not meeting the standards in the treatment effect evaluation results, determine the weight assignment adjustment strategy corresponding to the target improved influent working condition data in the influent working condition library, where the influent working condition library includes multiple influent working condition data, the influent working condition library is established based on historical influent performance data, the influent working condition data includes at least one of water quality, water volume, temperature, and air pressure, and each influent working condition data is respectively set with an initial weight assignment.

[0037] Step 202: Based on the weight assignment adjustment strategy, adjust the initial weight assignment corresponding to the target improved influent condition data, so that the leachate treatment system resets the operating parameters of the treatment equipment in each sub-process treatment system based on the influent condition library with the adjusted initial weight assignment.

[0038] In the above embodiments of the present application, specifically, as Figure 3 shown, the leachate treatment system includes, for example, multiple sub-process treatment systems such as pretreatment, biological treatment, and advanced treatment. Each system is equipped with corresponding treatment equipment, such as a grille, an adjustment tank, an anaerobic reactor, an aerobic reactor, a membrane filtration device, etc.

[0039] An influent condition library is established based on historical influent performance data. The influent condition library contains various influent condition data, such as water quality (COD, BOD biochemical oxygen demand, ammonia nitrogen, pH, etc.), water volume, air temperature, and air pressure, etc., and is normalized. At the same time, initial weight assignments can be set, for example, 0.2, 0.2, 0.5, 0.1 respectively. Different condition model libraries can also be divided according to the calculation results and combined with expert experience according to fuzzy rules for setting the operating parameters of subsequent treatment equipment.

[0040] After treating a batch of leachate (corresponding to one treatment cycle), an effect evaluation is carried out, and it is found that the chemical oxygen demand (COD) and ammonia nitrogen concentrations in the effluent both exceed the discharge standards.

[0041] Based on the results of this treatment effect evaluation, it can be inferred that the high COD and high ammonia nitrogen concentrations in the influent are the main reasons for the exceeding of the effluent standards. Therefore, it is necessary to focus on analyzing the data related to water quality in the influent condition library, especially the influent concentrations of COD and ammonia nitrogen and their corresponding weight assignments.

[0042] Next, based on the analysis of the treatment effect evaluation results and the influent condition library, the following weight assignment adjustment strategy can be formulated:

[0043] For example, increase the weight of the COD influent concentration: Since the effluent COD exceeds the standard, it indicates that the weight assignment of COD in the current influent condition library may not be sufficient to reflect its impact on the treatment effect. Therefore, it is necessary to appropriately increase the weight of the COD influent concentration. Or increase the weight of the ammonia nitrogen influent concentration. Similarly, since the effluent ammonia nitrogen exceeds the standard, it is also necessary to increase the weight of the ammonia nitrogen influent concentration. And or maintain or slightly adjust the weights of other influent condition data: For other influent condition data such as water volume, air temperature, and air pressure, if their impacts on the treatment effect are not significant in this evaluation, their initial weight assignments can be maintained or slightly adjusted.

[0044] Next, according to the formulated weight assignment adjustment strategy, the weight assignments corresponding to the influent COD and ammonia nitrogen concentrations in the influent operating condition library are adjusted. After the adjustment is completed, the leachate treatment system will re-set the operating parameters of the treatment equipment in each sub-process treatment system based on the new weight assignment influent operating condition library.

[0045] For example:

[0046] For the pretreatment system: The interception ability of the grille can be enhanced to reduce the suspended solids entering the regulating tank; at the same time, the aeration volume in the regulating tank may need to be increased to improve the biodegradability of COD.

[0047] For the biological treatment system: The residence times of the anaerobic reactor and the aerobic reactor can be increased to improve the removal efficiencies of COD and ammonia nitrogen; at the same time, the dosage of nutrients can be adjusted to maintain the normal growth and metabolism of microorganisms.

[0048] For the advanced treatment system: The cleaning frequency of the membrane filtration device can be increased or the filter element can be replaced to reduce membrane fouling and improve the effluent quality.

[0049] In particular, water quality and water volume will have a significant impact on the operating efficiency of the biological treatment system. Especially when the water quality fluctuates greatly or the water volume exceeds the design range, the performance of the biological treatment system will significantly decline. And the air temperature will have a certain impact on the operating efficiency of the equipment in the pretreatment and advanced treatment systems, but compared with water quality and water volume, its impact degree is smaller. The impact of air pressure on the system performance is relatively small, but under certain extreme weather conditions, the change in air pressure may also have a certain impact on the system.

[0050] Therefore, considering the impacts of water quality, water volume and water temperature on the system, the weight assignment adjustment strategy can also be: Adjust the weights of water quality and water volume from the original 60% (water quality) + 30% (water volume) to 70% (water quality) + 25% (water volume). At the same time, appropriately adjust the weight assignment of air temperature to better reflect its impact on the operating efficiency of the pretreatment and advanced treatment systems. For example, adjust the weight of air temperature from the original 10% to 12%. Keep the weight assignment of air pressure unchanged because its impact on the system performance is relatively small. After the adjustment, system verification can be carried out. By comparing the system performance before and after the adjustment, verify the effectiveness of the weight assignment adjustment strategy.

[0051] By applying the technical solution of this embodiment, the leachate treatment system can more accurately identify and handle the key factors affecting the treatment effect, thereby improving the effluent quality, and can scientifically and reasonably formulate the weight assignment adjustment strategy for different types of influent operating condition data in the influent operating condition library according to the system evaluation results. These strategies help to better reflect the impact of influent operating condition data on the performance of the leachate treatment system, thereby improving the operating efficiency and stability of the system.

[0052] Further, as a refinement and extension of the specific implementation manner of the above embodiment, in order to fully illustrate the specific implementation process of this embodiment, another method for evaluating the leachate treatment effect is provided, which is applied to a leachate treatment system. The leachate treatment system includes multiple sub-process systems, and the sub-process systems include an adjustment tank treatment system, an anaerobic treatment system, a primary biochemical treatment system, and a secondary biochemical treatment system. As Figure 4 shown, this method includes:

[0053] Step 301, within a preset evaluation period, for any sub-process system, obtain various single-cycle performance data of the sub-process system when treating the target treated leachate in each treatment cycle.

[0054] Step 302, for any type of single-cycle performance data, based on the corresponding type of single-cycle performance data of each treatment cycle of the sub-process system within the preset evaluation period, take the average value to obtain a type of performance data of the sub-process system when treating the target treated leachate within the preset evaluation period. Among them, the performance data includes the water quality index value of the target treated leachate after being treated, the initial pollutant concentration of the target treated leachate before being treated, the final pollutant concentration of the target treated leachate after being treated, and the actual treated water volume during the process of the sub-process system treating the target treated leachate. The water quality index value includes at least one of biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, and total organic carbon. In the leachate treatment system, each sub-process system corresponds to a treatment device. The preset evaluation period includes multiple treatment cycles, and a single treatment cycle is the cycle for the leachate treatment system to completely treat the leachate once.

[0055] In the above embodiment of the present application, when obtaining the performance data, the average value of each treatment cycle within the preset evaluation period can be taken. Specifically, within the preset evaluation period, for any sub-process system, respectively obtain various single-cycle performance data of the sub-process system when treating the target treated leachate in each treatment cycle. For any type of single-cycle performance data, based on the average value of the corresponding type of single-cycle performance data of each treatment cycle of the sub-process system within the preset evaluation period, obtain the type of performance data of the sub-process system when treating the target treated leachate within the preset evaluation period.

[0056] Step 303, based on the multiple performance data of any sub-process system, respectively obtain the to-be-evaluated performance index values of the sub-process system on each performance index, where the performance index includes water quality index, pollutant removal rate, and effluent efficiency.

[0057] Next, based on the performance data of any sub-process system, obtain the to-be-evaluated performance index values of the sub-process system on each performance index for subsequent system evaluation.

[0058] Optionally, based on the multiple performance data of any sub-process system, the to-be-evaluated performance index values of the sub-process system on each performance index are respectively obtained with reference to Figure 5 as shown below, and specifically include:

[0059] Step 3031: For any sub-process system, based on the water quality index value of the sub-process system, obtain the to-be-evaluated index value of the sub-process system on the water quality index.

[0060] Step 3032: Calculate the difference between the final concentration and the initial concentration of pollutants in the sub-process system, and based on the ratio of the calculated difference to the initial concentration of pollutants, obtain the to-be-evaluated performance index value of the sub-process system on the pollutant removal rate.

[0061] Step 3033: Based on the ratio of the actual water treatment volume of the sub-process system to the preset standard water treatment volume, obtain the to-be-evaluated performance index value of the sub-process system on the water outlet efficiency.

[0062] When calculating performance data, based on the water quality index value of the sub-process system, obtain the to-be-evaluated performance index value of the sub-process system on the water quality index. For the pollutant removal rate and water outlet efficiency of the leachate treatment system, they can be calculated in the following ways:

[0063] The formula for calculating the pollutant removal rate is: Removal rate (%) = (Initial concentration - Final concentration) / Initial concentration × 100%. Taking the chemical oxygen demand (COD) removal rate as an example, its formula is: COD removal rate (%) = (COD influent - COD effluent) / COD influent × 100%. Among them, COD influent represents the COD concentration in the water before treatment, and COD effluent represents the COD concentration in the water after treatment. This formula calculates the removal ratio of COD by comparing the concentration differences before and after treatment, so as to evaluate the treatment effect.

[0064] The water outlet efficiency can be evaluated according to the designed treatment capacity of the treatment system and the actual water treatment volume. Regarding the preset standard water treatment volume, according to the design and scale of the treatment system, the maximum leachate volume that can be treated daily or hourly can be determined.

[0065] For the actual water treatment volume, for example, within a period of time (such as one day, one week, one month, half a year or one year), record the actual leachate volume treated by each sub-process system in each treatment cycle. Finally, record the average value of the leachate volumes in multiple treatment cycles. By comparing the actual water treatment volume (average value) with the designed treatment capacity, the water outlet efficiency of the system can be calculated. For example, if the designed treatment capacity is 100 m 3 / d, and the actual water treatment volume is 90 m 3 / d, then the water outlet efficiency is 90%.

[0066] Alternatively, the effluent efficiency can also be indirectly reflected by the effluent quality compliance rate. Under the condition of continuously monitoring the effluent quality, record the number of days or times of compliance, and calculate the proportion of the total monitoring days or times, then the effluent quality compliance rate can be obtained, which also reflects the effluent efficiency of the system from the side.

[0067] It should be noted that in order to improve the removal rate and effluent efficiency, the treatment process and parameters can be optimized, such as adjusting the reaction time, temperature, pressure, etc., to improve the treatment efficiency. At the same time, strengthening the quality control of raw materials and products is also crucial.

[0068] Step 304, for any sub-process system, when it is determined that the performance index corresponding to the to-be-evaluated performance index value meets the standard based on the to-be-evaluated performance index value corresponding to the sub-process system and the preset performance judgment threshold of the performance index corresponding to the to-be-evaluated performance index value, the evaluation result of the sub-system treatment effect of the sub-process system within the preset evaluation period is compliant.

[0069] Step 305, when it is determined that the performance index corresponding to the to-be-evaluated performance index value does not meet the standard based on the to-be-evaluated performance index value corresponding to the sub-process system and the preset performance judgment threshold of the performance index corresponding to the to-be-evaluated performance index value, the evaluation result of the sub-system treatment effect of the sub-process system within the preset evaluation period is non-compliant.

[0070] Step 306, when there is a non-compliant evaluation result of the sub-system treatment effect, the evaluation result of the treatment effect of the leachate treatment system within the preset evaluation period is unqualified.

[0071] Step 307, when there is no non-compliant evaluation result of the sub-system treatment effect, the evaluation result of the treatment effect of the leachate treatment system within the preset evaluation period is qualified.

[0072] Step 308, determine the target improved sub-process system with a non-compliant evaluation result of the sub-system treatment effect.

[0073] Step 309, obtain the improvement measures corresponding to the target improved sub-process system, and improve the target improved sub-process system based on the improvement measures so that the improved sub-process system processes the new target treated leachate, where the improvement measures include at least one of optimizing the operating parameters of the treatment equipment, adding treatment processes, and installing monitoring equipment, and the monitoring equipment is used to monitor the operating parameter data of the treatment equipment during the treatment process.

[0074] Next, for example, for a leachate treatment system equipped in a domestic waste incineration plant, the main performance indicators of the system include the concentrations of effluent COD (chemical oxygen demand), BOD5 (biochemical oxygen demand over five days), NH3-N (ammonia nitrogen), and the overall pollutant removal rate of the system. The preset evaluation period is one month, and the preset performance judgment thresholds are set according to industry standards and system design requirements as follows: effluent COD ≤ 60 mg / L, BOD5 ≤ 20 mg / L, NH3-N ≤ 10 mg / L, and the system pollutant removal rate ≥ 99%. The process of obtaining the evaluation result of the subsystem treatment effect within the preset evaluation period based on the performance indicator values to be evaluated and the preset performance judgment thresholds of the corresponding performance indicators is as follows, for example:

[0075] Regarding the effluent COD: Preset performance judgment threshold: ≤ 60 mg / L;

[0076] Actual performance indicator value to be evaluated (average value within one month): 55 mg / L;

[0077] Comparison result: The actual performance indicator value is lower than the preset performance judgment threshold, meeting the standard.

[0078] Regarding the effluent BOD5: Preset performance judgment threshold: ≤ 20 mg / L;

[0079] Actual performance indicator value to be evaluated (average value within one month): 18 mg / L;

[0080] Comparison result: The actual performance indicator value is lower than the preset performance judgment threshold, meeting the standard.

[0081] Regarding the effluent NH3-N:

[0082] Preset performance judgment threshold: ≤ 10 mg / L;

[0083] Actual performance indicator value to be evaluated (average value within one month): 12 mg / L;

[0084] Comparison result: The actual performance indicator value is higher than the preset performance judgment threshold, not meeting the standard.

[0085] Regarding the pollutant removal rate:

[0086] Preset performance judgment threshold: ≥ 99%;

[0087] Actual performance indicator value to be evaluated (average value within one month): 99.5%;

[0088] Comparison result: The actual performance indicator value is higher than the preset performance judgment threshold, meeting the standard.

[0089] Based on the above comparison results, it can be concluded that the effluent COD and BOD5 concentrations and pollutant removal rates of the leachate treatment system meet the requirements within the preset evaluation period, showing good treatment effects.

[0090] However, the effluent NH3-N concentration is slightly higher than the preset performance judgment threshold, indicating that the leachate treatment system has deficiencies in ammonia nitrogen removal.

[0091] Therefore, the subsequent improvement measures can be: optimizing the operating parameters of the biological treatment unit to improve the ammonia nitrogen removal efficiency. Considering adding additional ammonia nitrogen removal processes such as chemical precipitation, stripping, or advanced oxidation. Strengthening the daily maintenance and monitoring of the system to ensure the stable operation of each treatment unit.

[0092] By applying the technical solution of this embodiment, the treatment effect of the leachate treatment system can be further improved to ensure that its effluent quality meets relevant standards and requirements.

[0093] Furthermore, as Figure 1 a specific implementation of the method, an embodiment of the present application provides a leachate treatment effect evaluation device, as Figure 6 shown. The device includes:
