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.

[0038] It should be noted that pretreatment equipment is used to remove large particle impurities, adjust pH and remove heavy metals in the leachate.

[0039] Among them, the intelligent supervision platform includes equipment inspection module, precise line classification module, leachate delivery decision module and leachate treatment quality evaluation module; the equipment inspection module inspects the processing equipment involved in the full-quantity processing line i one by one, determines the low-resistance equipment and the high-resistance equipment through inspection and obtains the line setting inspection value of the full-quantity processing line i, and sends the line setting inspection value of the full-quantity processing line i to the precise line classification module through the intelligent supervision platform, which can not only realize the effective detection and evaluation of all processing equipment, but also provide data support for the analysis process of the precise line classification module to ensure the accuracy of its analysis results; the specific operation process of the equipment inspection module is as follows:
[0040] The production date of the corresponding processing equipment in the fully quantified processing line i is collected, and the ratio of the interval between the current date and the production date of the corresponding processing equipment to the corresponding preset life span is marked as the production inspection value, wherein the larger the value of the production inspection value is, the closer the service life of the corresponding processing equipment is to the end; and the total actual operation time of the corresponding processing equipment within the interval between the current date and the production date is marked as the operation inspection value;
[0041] The number of failures of the corresponding processing equipment in the fully quantized processing line i during the historical operation is collected and marked as the processing failure value, and the duration of each suspension of operation due to a failure is collected and marked as the processing stop time value, all the processing stop time values are summed up to obtain the suspension time table value of the corresponding processing equipment, and the processing stop time value is numerically compared with the corresponding preset processing stop time threshold, and the number of processing stop time values exceeding the corresponding preset processing stop time threshold is calculated by ratio with the processing failure value to obtain the failure high table value;
[0042] The production inspection value FSi, operation inspection value FYi, processing failure value FKi, pause table value FWi and failure high table value FPi of the corresponding processing equipment in the full-quantization processing line i are numerically calculated by the formula FXi=a1*FSi+(a2*FYi) / a1+a3*FKi+a4*FWi+a5*FPi to obtain the processing inspection value FXi, wherein a1, a2, a3, a4, a5 are preset proportional coefficients, and the values of a1, a2, a3, a4, a5 are all greater than zero; and the larger the value of the processing inspection value FXi, the worse the equipment condition of the corresponding processing equipment;
[0043] The processing inspection value FXi is numerically compared with the preset processing inspection threshold of the corresponding processing device. If the processing inspection value FXi exceeds the preset processing inspection threshold, it indicates that the equipment condition of the corresponding processing device is poor, and the corresponding processing device in the full quantization processing line i is marked as a high-resistance device; if the processing inspection value FXi does not exceed the preset processing inspection threshold, it indicates that the equipment condition of the corresponding processing device is good, and the corresponding processing device in the full quantization processing line i is marked as a low-resistance device.
[0044] Furthermore, after marking the corresponding processing devices in the full quantization processing line i as high-resistance devices or low-resistance devices, the number of high-resistance devices in the full quantization processing line i is collected, and the ratio of the number of high-resistance devices to the total number of devices in the full quantization processing line i is calculated to obtain a high-resistance detection value; and the processing inspection value of the corresponding processing device is ratio-calculated to the corresponding preset processing inspection threshold to obtain an inspection share value, and the inspection share values of all processing devices in the full quantization processing line i are averaged to obtain an inspection table value, and the high-resistance detection value GYi in the full quantization processing line i and the inspection table value GKi are numerically calculated by the formula GXi=ty1*GYi+ty2*GKi to obtain a line setting inspection value GXi; wherein ty1 and ty2 are preset proportional coefficients, ty1>ty2>0; and, the larger the numerical value of the line setting inspection value GXi, the worse the overall operating performance of the full quantization processing line i.
[0045] The precise line classification module is used to set the line classification detection cycle. Preferably, the line classification detection cycle is thirty days. Based on the line setting inspection value and the processing performance of the fully quantitative processing line i within the online classification detection cycle, it is graded, and the fully quantitative processing line i is marked as an excellent processing line, a good processing line or a poor processing line. The grading information of the fully quantitative processing line i is sent to the intelligent supervision platform for storage, which can not only realize the reasonable analysis and precise grading of each group of fully quantitative processing lines, but also help to automatically and reasonably transport the landfill leachate in the future. The specific operation process of the precise line classification module is as follows:
[0046] The total time of the landfill leachate treatment and the volume of the landfill leachate treated during the online detection period of the full-quantity treatment line i are collected and marked as the total liquid treatment time value and the total liquid treatment amount value, respectively. The total liquid treatment amount value is calculated by ratio with the total liquid treatment time value to obtain the liquid treatment efficiency inspection value; wherein, the larger the value of the liquid treatment efficiency inspection value is, the higher the treatment efficiency of the full-quantity treatment line i during the online detection period is; and the number of times that the water quality sample inspection unqualified signal is generated during the online detection period of the full-quantity treatment line i is collected, and the number of times that the water quality sample inspection unqualified signal is generated is calculated by ratio with the total liquid treatment time value to obtain the liquid treatment quality inspection value, wherein, the larger the value of the liquid treatment quality inspection value is, the worse the treatment effect of the full-quantity treatment line i during the online detection period is;
[0047] The line setting inspection value WSi, liquid treatment efficiency inspection value WYi and liquid treatment quality inspection value WKi of the full quantitative treatment line i are numerically calculated by the formula WPi=(fy1*WSi+fy3*WKi) / (fy2*WYi+fy1) to obtain the precise line score WPi, wherein fy1, fy2, fy3 are preset proportional coefficients, and the values of fy1, fy2, fy3 are all positive numbers; and the larger the value of the precise line score WPi is, the worse the operating condition of the full quantitative treatment line i is overall, and the more unfavorable it is to ensure the treatment effect and efficiency of the landfill leachate;
[0048] The precision line score WPi is numerically compared with the preset precision line score range. If the precision line score WPi exceeds the maximum value of the preset precision line score range, it indicates that the overall operation condition of the full quantitative processing line i is poor, and the full quantitative processing line i is marked as an inferior processing line; if the precision line score WPi is within the preset precision line score range, it indicates that the overall operation condition of the full quantitative processing line i is moderate, and the full quantitative processing line i is marked as a good processing line; if the precision line score WPi does not exceed the minimum value of the preset precision line score range, it indicates that the overall operation condition of the full quantitative processing line i is good, and the full quantitative processing line i is marked as an excellent processing line.
[0049] The leachate delivery decision module is used to conduct pollution detection and analysis on the corresponding landfill leachate before treating it. Through analysis, the fully-quantified treatment line that matches it is determined, and the landfill leachate is delivered to the fully-quantified treatment line that matches it, so as to realize the reasonable delivery of landfill leachate, ensure its treatment effect and efficiency, improve the intelligence and automation of landfill leachate treatment, and significantly reduce the management difficulty of managers. The specific analysis process of pollution detection and analysis is as follows:
[0050] The heavy metal data, suspended matter data, total phosphorus data, ammonia nitrogen data, chemical oxygen demand data, pH deviation data and viscosity data of the corresponding landfill leachate are collected, wherein the heavy metal data is a data value indicating the concentration of heavy metal ions in the landfill leachate, the suspended matter data is a data value indicating the concentration of suspended particles in the landfill leachate, the total phosphorus data is a data value indicating the phosphorus content in the landfill leachate, and the ammonia nitrogen data is a data value indicating the ammonia nitrogen concentration in the landfill leachate; the chemical oxygen demand data reflects the ability of organic matter in the water body to be decomposed by microorganisms, that is, the data value indicating the organic matter content; the pH deviation data is a data value indicating the deviation of the pH value of the landfill leachate from the median of the preset pH value range, and the viscosity data is a data value indicating the viscosity of the landfill leachate;
[0051] The heavy metal data, suspended solids data, total phosphorus data, ammonia nitrogen data, chemical oxygen demand data, pH deviation data and viscosity data are numerically compared with the corresponding preset thresholds. If the heavy metal data, suspended solids data, total phosphorus data, ammonia nitrogen data, chemical oxygen demand data, pH deviation data and viscosity data do not exceed the corresponding preset thresholds, it indicates that the pollution of the landfill leachate is relatively light and easier to treat, and the pollution symbol WF-1 is assigned to it;
[0052] If at least one of the heavy metal data, suspended solids data, total phosphorus data, ammonia nitrogen data, chemical oxygen demand data, pH deviation data or viscosity data exceeds the corresponding preset threshold, the data exceeding the corresponding preset threshold is marked as over-amplitude data; and the heavy metal data, suspended solids data, total phosphorus data, ammonia nitrogen data, chemical oxygen demand data, pH deviation data and viscosity data are respectively set to correspond to a set of preset weight values, wherein the values of the preset weight values are all greater than zero; the excess value of the over-amplitude data compared to the corresponding preset threshold is marked as an over-amplitude detection value, the over-amplitude detection value is multiplied by the corresponding preset weight value to obtain the over-amplitude impact value, and the over-amplitude impact values of all over-amplitude data in the landfill leachate are summed and calculated to obtain the leachate analysis value;
[0053] It should be noted that the larger the value of the leachate analysis value, the more serious the pollution condition of the garbage leachate, and the more difficult it is to effectively treat the garbage treatment liquid; the leachate analysis value is compared with the preset leachate analysis threshold value. If the leachate analysis value does not exceed the preset leachate analysis threshold value, it indicates that the pollution condition of the garbage leachate is relatively serious, and the pollution symbol WF-2 is assigned to it; if the leachate analysis value exceeds the preset leachate analysis threshold value, it indicates that the pollution condition of the garbage leachate is extremely serious, and the pollution symbol WF-3 is assigned to it.
[0054] Furthermore, after the corresponding landfill leachate is assigned the pollution symbol WF-1, WF-2 or WF-3, the fully quantitative treatment line that matches it is determined. The inferior treatment line is used to treat the landfill leachate corresponding to the pollution symbol WF-1, the good treatment line is used to treat the landfill leachate corresponding to the pollution symbols WF-1 and WF-2, and the superior treatment line is used to treat the landfill leachate corresponding to the pollution symbols WF-1, WF-2 and WF-3, thereby realizing the reasonable transportation of the landfill leachate, with a high degree of intelligence and automation, reducing the workload of management personnel and improving the treatment effect and efficiency of the landfill leachate.
[0055] The leachate treatment quality evaluation module is used to test the quality of the liquid output by the corresponding full-quantity treatment line, and to determine whether the quality of the output liquid meets the requirements through analysis, and to generate a water quality sample inspection qualified signal or a water quality sample inspection unqualified signal, and send the water quality sample inspection unqualified signal to the background supervision end through the intelligent supervision platform. When the background supervision end receives the water quality sample inspection unqualified signal, it will issue a corresponding warning. When the management personnel receive the corresponding warning, they should promptly investigate the cause and take corresponding improvement measures, such as secondary treatment of the output liquid, so as to effectively reduce the pollution caused by the discharged liquid to the environment; the specific operation process of the leachate treatment quality evaluation module is as follows:
[0056] Obtain all water quality parameters that need to be tested after the leachate is treated (such as transparency, pH value, heavy metal concentration, etc.), and compare the test data of all water quality parameters with the corresponding data requirements one by one, for example, whether the heavy metal concentration is lower than the corresponding data threshold, whether the pH value is within the corresponding data range, etc.; if there are water quality parameters that do not meet the corresponding data requirements, indicating that the corresponding treatment process does not meet the standards and the treated liquid does not meet the discharge requirements, then a water quality sample inspection failure signal is generated; if all water quality parameters meet the corresponding data requirements, indicating that the corresponding treatment process meets the standards and the treated liquid meets the discharge requirements, then a water quality sample inspection pass signal is generated.
[0057] Embodiment 2: Figure 2 As shown, the difference between this embodiment and embodiment 1 is that the intelligent supervision platform further includes a comprehensive planning module, which is used to set a planning period, preferably, the planning period is forty-five days; the volume of the garbage leachate to be processed is collected in real time and marked as the leachate waiting net value, the leachate waiting net value is compared with the preset leachate waiting net threshold, if the leachate waiting net value exceeds the preset leachate waiting net threshold, it indicates that there is a large amount of garbage leachate waiting to be processed at the corresponding time, then it is judged that the corresponding time is in a busy operation state;
[0058] The duration of each busy operation state is collected and marked as the busy operation value. All busy operation values in the planning period are summed up to obtain the busy operation value, and the busy operation value is compared with the preset busy operation threshold. If the busy operation value exceeds the preset busy operation threshold, the corresponding busy operation value is marked as the busy operation analysis value, and the number of busy operation analysis values is marked as the high busy operation frequency detection value.
[0059] The total time that the fully quantified treatment line i has not been used for leachate treatment within the planning period is collected and marked as the air transport time, and the air transport time of all fully quantified treatment lines is averaged to obtain the treatment line idling value, and the operation busyness value RF, the operation high busyness frequency detection value RK and the treatment line idling value RS are numerically calculated by the formula RX=(ew1*RF+ew2*RK) / (ew3*RS+1) to obtain the planning evaluation value RX; wherein ew1, ew2, and ew3 are preset proportional coefficients, ew2>ew1>ew3>0; and the larger the numerical value of the planning evaluation value RX, the more insufficient the treatment capacity of the leachate is;
[0060] The planning evaluation value RX is numerically compared with the preset planning evaluation threshold. If the planning evaluation value RX exceeds the preset planning evaluation threshold, indicating that the treatment capacity of the landfill leachate is insufficient, a planning emergency warning signal is generated, and the planning emergency warning signal is sent to the background supervision end via the intelligent supervision platform. The background supervision end issues a corresponding warning when receiving the planning emergency warning signal. After receiving the warning, the management personnel need to promptly upgrade the corresponding equipment or increase the full-quantity processing line to improve the processing efficiency, so as to ensure the subsequent processing capacity, further improve the degree of intelligence and reduce the management difficulty of the management personnel.
[0061] The working principle of the present invention is as follows: when in use, the landfill leachate is comprehensively treated through the full-quantity treatment line to achieve efficient treatment and full-quantity compliance of the landfill leachate, ensure the safety of the output liquid and reduce the pollution to the environment, and the processing equipment involved in the full-quantity treatment line i is inspected one by one through the equipment inspection module, and the low-resistance equipment and the high-resistance equipment are determined through the inspection and the line setting inspection value of the full-quantity treatment line i is obtained, so as to achieve effective detection and evaluation of all processing equipment, and the precise line classification module classifies the landfill leachate based on the line setting inspection value and the processing performance of the full-quantity treatment line i within the online classification detection cycle, so as to achieve reasonable analysis and precise classification of each group of full-quantity treatment lines, and the leachate transportation decision module performs pollution detection and analysis on the corresponding landfill leachate before treating it, and determines the full-quantity treatment line that matches it through analysis, and transports the landfill leachate to the full-quantity treatment line that matches it, so as to achieve reasonable transportation of the landfill leachate, ensure its treatment effect and treatment efficiency, improve the intelligence and automation of landfill leachate treatment, and significantly reduce the management difficulty and workload of management personnel.
