Description

Technical Field

[0001] The present invention relates to the technical field of landfill pollution risk prevention and control, and in particular to a monitoring system and method for landfill pollution risk prevention and control. Background Art

[0002] Landfills are places where garbage is concentrated and stored in a sanitary manner. Landfills generally use a layered landfill method to process garbage. After a layer of garbage is piled up, it is covered with a layer of loess, which can easily reduce the pollution of garbage. The construction of landfills includes procedures such as site selection, design and construction, conditions for the entry of landfill waste, operation, closure, post-maintenance and management, and pollutant control and monitoring.

[0003] Landfills are mainly used to bury toxic and hazardous substances that are not easy to dispose of. They are the final destination for the disposal of toxic and hazardous substances. Their function is to effectively isolate some wastes from human production and life from the biosphere to prevent secondary pollution and play a good role in environmental protection. Since the toxic and hazardous substances buried in landfills exceed the standard and are highly toxic, if effective risk prevention is not done, it is easy to cause leakage to varying degrees, endangering public safety and causing sudden environmental incidents. Therefore, in the daily operation of landfills, various risk factors that are likely to be caused should be effectively analyzed, and work experience should be continuously summarized to reduce the pollution risk to the lowest level. Once environmental pollution factors appear, measures should be taken immediately for effective monitoring to ensure the safe operation of landfills. Summary of the invention

[0004] The present invention provides a monitoring system and method for landfill pollution risk prevention and control, which can prevent and control the landfill pollution risk and reduce the pollution risk in time.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the embodiments of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0040] The disclosure below provides many different embodiments or examples to implement different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention. In addition, the embodiments of the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0041] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] like Figure 1 As shown, the embodiment of this specification discloses a monitoring method for landfill pollution risk prevention and control, including:

[0043] Obtain leachate pollution degree, gas pollution degree, groundwater pollution degree, soil pollution degree and overall pollution degree;

[0044] The gas pollution degree is used as a row vector, the leachate pollution degree is used as a column vector, a first matrix is ​​formed, and then the overall pollution degree is imported, a surface fitting operation is performed, a three-dimensional surface and a gas pollution degree surface fitting equation are obtained, and the three-dimensional surface is recorded as a first pollution reference domain;

[0045] The groundwater pollution degree is used as a row vector, the leachate pollution degree is used as a column vector, a second matrix is ​​formed, and then the overall pollution degree is imported, and a surface fitting operation is performed to obtain a three-dimensional surface and a groundwater pollution degree surface fitting equation, and the three-dimensional surface is recorded as a second pollution reference domain;

[0046] The soil pollution degree is used as a row vector, the leachate pollution degree is used as a column vector, a third matrix is ​​formed, and then the overall pollution degree is imported, a surface fitting operation is performed, a three-dimensional surface and a soil pollution degree surface fitting equation are obtained, and the three-dimensional surface is recorded as a third pollution reference domain;

[0047] Based on the first pollution reference domain, the second pollution reference domain and the third pollution reference domain, the real-time leachate pollution level, the real-time gas pollution level, the real-time groundwater pollution level and the real-time soil pollution level are adjusted so that the real-time overall pollution level is less than the landfill pollution risk prevention and control threshold.

[0048] In some embodiments, real-time leachate pollution, real-time gas pollution, real-time groundwater pollution, real-time soil pollution and real-time overall pollution are obtained;

[0049] When the real-time overall pollution level is greater than the landfill pollution risk prevention and control threshold, the real-time gas pollution level is substituted into the gas pollution level surface fitting equation to obtain the target value. If the target value is greater than 0, the first leachate pollution level corresponding to the real-time gas pollution level is obtained based on the first pollution reference domain.

[0050] Substituting the real-time groundwater pollution degree into the groundwater pollution degree surface fitting equation to obtain a target value, and if the target value is greater than 0, obtaining a second leachate pollution degree corresponding to the real-time groundwater pollution degree based on a second pollution reference domain;

[0051] Substituting the real-time soil contamination degree into the soil contamination degree surface fitting equation to obtain a target value, and if the target value is greater than 0, obtaining a third leachate contamination degree corresponding to the real-time soil contamination degree based on a third pollution reference domain;

[0052] Compare the real-time leachate contamination with the average of the first leachate contamination, the second leachate contamination and the third leachate contamination. If the real-time leachate contamination is greater than or equal to the average of the three, adjust the real-time leachate contamination, the real-time gas contamination, the real-time groundwater contamination and the real-time soil contamination until the real-time overall contamination is less than the landfill pollution risk prevention and control threshold;

[0053] If the real-time leachate pollution level is less than the average of the three, the real-time gas pollution level, the real-time groundwater pollution level and the real-time soil pollution level will be adjusted until the real-time overall pollution level is less than the landfill pollution risk prevention and control threshold.

[0054] The embodiment of this specification also discloses a monitoring system for landfill pollution risk prevention and control, which is used to implement the monitoring method for landfill pollution risk prevention and control as described above;

[0055] The landfill pollution risk prevention and control monitoring system comprises:

[0056] The first acquisition module is used to obtain the pollution degree of leachate, gas, groundwater, soil and overall pollution degree;

[0057] A first fitting module is used to take the gas pollution degree as a row vector and the leachate pollution degree as a column vector to form a first matrix, then import the overall pollution degree, perform a surface fitting operation, obtain a three-dimensional surface and a gas pollution degree surface fitting equation, and record the three-dimensional surface as a first pollution reference domain;

[0058] A second fitting module is used to use the groundwater pollution degree as a row vector and the leachate pollution degree as a column vector to form a second matrix, then import the overall pollution degree, perform a surface fitting operation, obtain a three-dimensional surface and a groundwater pollution degree surface fitting equation, and record the three-dimensional surface as a second pollution reference domain;

[0059] A third fitting module is used to use the soil pollution degree as a row vector and the leachate pollution degree as a column vector to form a third matrix, then import the overall pollution degree, perform a surface fitting operation, obtain a three-dimensional surface and a soil pollution degree surface fitting equation, and record the three-dimensional surface as a third pollution reference domain;

[0060] The pollution risk prevention and control module is used to adjust the real-time leachate pollution degree, the real-time gas pollution degree, the real-time groundwater pollution degree, and the real-time soil pollution degree based on the first pollution reference domain, the second pollution reference domain, and the third pollution reference domain, so that the real-time overall pollution degree is less than the landfill pollution risk prevention and control threshold.

[0061] In some embodiments, the landfill pollution risk prevention and control monitoring system further includes:

[0062] The second acquisition module is used to obtain real-time leachate pollution degree, real-time gas pollution degree, real-time groundwater pollution degree, real-time soil pollution degree and real-time overall pollution degree;

[0063] The third acquisition module is used to substitute the real-time gas pollution into the gas pollution surface fitting equation to obtain the target value when the real-time overall pollution degree is greater than the landfill pollution risk prevention and control threshold value, and if the target value is greater than 0, obtain the first leachate pollution degree corresponding to the real-time gas pollution degree based on the first pollution reference domain;

[0064] A fourth acquisition module is used to substitute the real-time groundwater pollution degree into the groundwater pollution degree surface fitting equation to obtain a target value. If the target value is greater than 0, a second leachate pollution degree corresponding to the real-time groundwater pollution degree is obtained based on a second pollution reference domain;

[0065] A fifth acquisition module is used to substitute the real-time soil contamination degree into the soil contamination degree surface fitting equation to obtain a target value. If the target value is greater than 0, a third leachate contamination degree corresponding to the real-time soil contamination degree is obtained based on a third pollution reference domain;

[0066] The pollution risk prevention and control module is also used to compare the real-time leachate pollution degree with the average of the first leachate pollution degree, the second leachate pollution degree and the third leachate pollution degree. If the real-time leachate pollution degree is greater than or equal to the average of the three, the real-time leachate pollution degree, the real-time gas pollution degree, the real-time groundwater pollution degree and the real-time soil pollution degree are adjusted until the real-time overall pollution degree is less than the landfill pollution risk prevention and control threshold;

[0067] If the real-time leachate pollution level is less than the average of the three, the real-time gas pollution level, the real-time groundwater pollution level and the real-time soil pollution level will be adjusted until the real-time overall pollution level is less than the landfill pollution risk prevention and control threshold.

[0068] In practice, before surface fitting, the matrix can be preprocessed to remove NaN values ​​or 0 values, and then the leachate contamination degree can be imported to perform the surface fitting operation.

[0069] It is clear that the relevant regulation of the pollution degree of the leachate, the pollution degree of the gas, the pollution degree of the groundwater, and the pollution degree of the soil are existing technologies, and the present invention does not improve them. The regulation technology can refer to the existing technology. For example, the pollution degree of the leachate is the total proportion of various pollutants in the leachate (it can be a concentration ratio, a weight ratio, a volume ratio, a component percentage or other ratios). In some embodiments, the pollution degree of the leachate includes but is not limited to the first organic pollution degree, the first heavy metal pollution degree and the pathogen pollution degree. Correspondingly, reducing the proportion of the first organic pollution in the leachate is to reduce the first organic pollution degree, and so on. The measures for treating (purifying) the first organic pollution belong to the existing technology and will not be repeated here. In practice, when reducing the pollution degree, the proportion of the pollutant with the highest proportion can be reduced first. When reducing any of the pollution levels of leachate, gas, groundwater and soil, it will affect the pollution levels of other factors. The surface fitting method can well reflect the degree of influence among the pollution levels of leachate, gas, groundwater and soil, thereby maximizing the efficiency of reducing the overall pollution level.

[0070] It should be understood that the overall pollution level refers to the overall proportion of all pollutants in the landfill in the leachate, gas, groundwater and soil, that is, the sum of the pollution level of the leachate, gas, groundwater and soil. The landfill pollution risk control threshold can be set according to the actual situation of the landfill, for example, the average value (annual average, monthly average, daily average, etc.) of the overall pollution level of the landfill (which can be other landfills) in the historical data is used as the threshold.

[0071] In some embodiments, the gas pollution degree includes but is not limited to carbon dioxide pollution degree, methane pollution degree, ammonia pollution degree, hydrogen sulfide pollution degree, methyl sulfide pollution degree and dimethyl disulfide pollution degree. The description of gas pollution degree can refer to the above description of leachate pollution degree, which will not be repeated here.

[0072] In some embodiments, the groundwater contamination degree includes, but is not limited to, aromatic compound contamination degree, chlorinated aromatic compound contamination degree, phosphate ester contamination degree, phthalate ester contamination degree, phenol compound contamination degree, and aniline compound contamination degree. The description of groundwater contamination degree can refer to the above description of leachate contamination degree, which will not be repeated here.

[0073] In some embodiments, the soil contamination degree includes, but is not limited to, a second organic matter contamination degree, a second heavy metal contamination degree, a radioactive substance contamination degree, a pathogenic bacteria contamination degree, a toxic substance contamination degree, and a corrosive substance contamination degree. The description of the soil contamination degree can refer to the above description of the leachate contamination degree, which will not be repeated here.

[0074] It should be understood that the above surface fitting operation can use existing software tools, such as the CurveFitting tool in Matlab. The above modules can be existing data detection (collection) / measurement devices / sensors or data reading modules of the monitoring system for landfill pollution risk prevention and control, and can directly obtain corresponding data.

[0075] It is clear that by obtaining the corresponding data in the monitoring system for landfill pollution risk prevention and control through existing equipment in advance, a large amount of test data can be obtained. These test data can be simulation experiment data in the laboratory or actual measured or operating data of the monitoring system for landfill pollution risk prevention and control in practice.

[0076] The above-described embodiments are used to illustrate the present invention, not to limit the present invention, so changes in the exemplified values ​​or replacement of equivalent elements should still fall within the scope of the present invention.

For example, "one embodiment", "an embodiment", and / or "some embodiments" refer to a certain feature, structure or characteristic related to at least one embodiment of the present application.

A monitoring system for landfill pollution risk prevention and control, characterized in that: Used to implement the monitoring method for landfill pollution risk prevention and control as described in claim 1; The landfill pollution risk prevention and control monitoring system comprises: The first acquisition module is used to obtain the pollution degree of leachate, gas, groundwater, soil and overall pollution degree; A first fitting module is used to take the gas pollution degree as a row vector and the leachate pollution degree as a column vector to form a first matrix, then import the overall pollution degree, perform a surface fitting operation, obtain a three-dimensional surface and a gas pollution degree surface fitting equation, and record the three-dimensional surface as a first pollution reference domain; A second fitting module is used to use the groundwater pollution degree as a row vector and the leachate pollution degree as a column vector to form a second matrix, then import the overall pollution degree, perform a surface fitting operation, obtain a three-dimensional surface and a groundwater pollution degree surface fitting equation, and record the three-dimensional surface as a second pollution reference domain; A third fitting module is used to take the soil pollution degree as a row vector and the leachate pollution degree as a column vector to form a third matrix, then import the overall pollution degree, perform a surface fitting operation, obtain a three-dimensional surface and a soil pollution degree surface fitting equation, and record the three-dimensional surface as a third pollution reference domain; a pollution risk prevention and control module is used to adjust the real-time leachate pollution degree, the real-time gas pollution degree, the real-time groundwater pollution degree, and the real-time soil pollution degree based on the first pollution reference domain, the second pollution reference domain, and the third pollution reference domain, so that the real-time overall pollution degree is less than the landfill pollution risk prevention and control threshold; The second acquisition module is used to obtain real-time leachate pollution degree, real-time gas pollution degree, real-time groundwater pollution degree, real-time soil pollution degree and real-time overall pollution degree; The third acquisition module is used to substitute the real-time gas pollution into the gas pollution surface fitting equation to obtain the target value when the real-time overall pollution degree is greater than the landfill pollution risk prevention and control threshold value, and if the target value is greater than 0, obtain the first leachate pollution degree corresponding to the real-time gas pollution degree based on the first pollution reference domain; A fourth acquisition module is used to substitute the real-time groundwater pollution degree into the groundwater pollution degree surface fitting equation to obtain a target value. If the target value is greater than 0, a second leachate pollution degree corresponding to the real-time groundwater pollution degree is obtained based on a second pollution reference domain; A fifth acquisition module is used to substitute the real-time soil contamination degree into the soil contamination degree surface fitting equation to obtain a target value. If the target value is greater than 0, a third leachate contamination degree corresponding to the real-time soil contamination degree is obtained based on a third pollution reference domain; The pollution risk prevention and control module is also used to compare the real-time leachate pollution degree with the average of the first leachate pollution degree, the second leachate pollution degree and the third leachate pollution degree. If the real-time leachate pollution degree is greater than or equal to the average of the three, the real-time leachate pollution degree, the real-time gas pollution degree, the real-time groundwater pollution degree and the real-time soil pollution degree are adjusted until the real-time overall pollution degree is less than the landfill pollution risk prevention and control threshold; If the real-time leachate pollution level is less than the average of the three, the real-time gas pollution level, the real-time groundwater pollution level and the real-time soil pollution level will be adjusted until the real-time overall pollution level is less than the landfill pollution risk prevention and control threshold.
