Description

Processing end selection method and system in solid waste cooperative disposal
Technical Field
The application relates to the technical field of solid waste disposal, in particular to a disposal end selection method and a disposal end selection system in solid waste cooperative disposal.
Background
In the process of social production and living, a large amount of solid wastes of different types are inevitably generated, such as iron-containing dust and mud, dust or a byproduct of wet desulphurization in a steel plant; fly ash of thermal power plants; waste catalysts from chemical plants, etc. At present, the main mode for disposing the solid waste is landfill, but before landfill, the solid waste may need to pass through a solid waste disposal plant with solid waste disposal capability for harmless and quantitative reduction disposal.
In addition, in addition to professional solid waste treatment plants, enterprises such as steel, thermal power, cement and the like have certain treatment capacity on solid waste, wherein different types of enterprises are suitable for treating different types of solid waste, for example, solid waste containing more iron elements is suitable for entering steel plants, and solid waste containing more calcium elements is suitable for entering cement plants. The existing solid wastes have mature disposal processes, wherein one type of solid wastes can be disposed in several manners, and one type of solid wastes can also be disposed in various types of solid wastes.
As shown in fig. 1, which is a schematic diagram of the distribution of disposal terminals and solid waste terminals in the prior art, the solid waste is generally disposed by a near disposal principle, that is, the solid waste is buried or processed in a factory near the location where the solid waste is generated, a solid waste landfill, a solid waste processing factory or an enterprise with a certain disposal capability is set up in an industrial park, and the solid waste in the area, that is, the solid waste generated in a certain area is digested by the solid waste landfill set up in the industrial park, and is processed in the area.
However, this principle of near disposal has several problems: (1) from the perspective of a larger area, small-scale solid waste disposal facilities (solid waste landfill sites, solid waste treatment plants or enterprises with certain disposal capacity) are arranged in various areas of the area, so that the problems of large overall occupied area, small scale of single solid waste disposal facilities and insufficient and optimized utilization of resources exist, when the solid waste amount generated in a certain area is large and exceeds the solid waste treatment capacity of the area, a large amount of solid waste is accumulated, the environment is possibly adversely affected, or part of the solid waste with useful value is lost after being placed for a long time. (2) From a global perspective, it is difficult to match their corresponding optimal solutions for various solid wastes. For example, an optimal disposal scheme for solid waste is used as an auxiliary material for the production of a first factory in an adjacent area, but is limited by information barriers and administrative divisions, and can be disposed only in the solid waste disposal factory in the area, so that the resource utilization rate is low; (3) when a large project is newly built in a certain area, a large amount of new reinforced solid wastes are generated, and the original disposal capacity in the area is difficult to match in time; or, the redundancy of the solid waste disposal capability in a certain area is low, and when the solid waste disposal facilities in the area are overhauled or equipment fails, the quantity of the solid waste disposal facilities in the area is limited, so that the solid waste generated in production and life in the area cannot be disposed in time, and the environment may be adversely affected.

Detailed Description
In order to solve the problems that the existing disposal method cannot fully utilize the resources of disposal equipment, is unreasonable in distribution, has low redundancy of disposal capability of solid waste in a small area and has poor risk resistance in the existing disposal method of the solid waste, the embodiment of the application provides a method and a system for selecting a disposal end in the solid waste cooperative disposal.
As shown in fig. 2, a schematic flow chart of a method for selecting a disposal terminal in solid waste cooperative disposal according to an embodiment of the present application is provided, and a method for selecting a disposal terminal in solid waste cooperative disposal according to a first aspect of the embodiment of the present application includes steps S201 to S205.
Step S201, acquiring solid waste information of a plurality of solid waste ends and disposal information of a plurality of disposal ends; the solid waste information comprises a solid waste position, a solid waste type, a solid waste stock and a limit storage amount, and the disposal information comprises a disposal position, a disposal type, a disposal speed and a disposal stock.
Step S202, determining the storage rate of the solid waste end according to the solid waste inventory and the limit storage amount of the solid waste end, and marking the solid waste end as the solid waste end to be treated if the storage rate is greater than or equal to a preset inventory threshold value.
The preset inventory threshold is set according to the actual condition of the solid waste, for example, according to the size of the site where the solid waste is stored in the solid waste or the storage time of the solid waste type, the preset inventory threshold is set.
It should be noted that, in some embodiments, the solid waste end to be disposed may be screened from a time perspective, for example, in a specific implementation process, the step S202 is replaced by obtaining a solid waste yield of the solid waste end, and a first time when the solid waste stock reaches a limit storage amount is determined according to the solid waste yield and the solid waste stock of the solid waste end, and if the first time is less than or equal to a preset second time, the solid waste end is marked as the solid waste end to be disposed, where the limit storage amount is an upper limit amount of the solid waste storage of the solid waste end.
In the practical application process, the solid waste yield of the solid waste end is generally stable, but the solid waste yield is also in sudden change, for example, the production plan is changed, so that a large amount of solid waste of a certain kind is generated in the next stage, and the dynamic change of the solid waste stock can be monitored in a limited way by considering the first time when the solid waste stock reaches the limit storage capacity, so that the solid waste yield of the solid waste end is fully considered, the problem that the solid waste stock is suddenly increased due to the change of the stage solid waste yield when the solid waste end is neglected, and the solid waste accumulation of the solid waste end is caused is avoided.
Step S203, matching the solid waste type of the solid waste end to be disposed with the disposal types of all disposal ends, and marking the corresponding disposal end as a first pre-selection disposal end if the disposal type of the disposal end includes the solid waste type of the solid waste end to be disposed.
It should be noted that, since the types of solid wastes generated by the solid waste end may be more than one, or the types of solid wastes generated at different times are different, and similarly, the types of solid wastes processed at all the processing ends may be more than one, or the types of solid wastes processed at different times are different, it is necessary to obtain or determine the types of solid wastes at the solid waste end to be processed and the types of processing at the processing end each time, and the processing end whose types include the types of solid wastes at the solid waste end to be processed is marked as the first pre-selected processing end by screening the types of processing at the processing end.
It should be noted that the solid waste is classified according to the organic matter content, the combustion heat value, the carbon content, or the metal element type and content of the solid waste.
Specifically, the solid waste is classified according to the organic matter content of the solid waste, for example, the solid with higher organic matter content can be used in a combustion manner due to the fact that the solid can be combusted and the combustion heat value is higher, such as biomass, plastics, waste activated carbon powder and the like, and can be mixed into sintering, a blast furnace, a power station boiler and the like to use heat energy in a combustion manner; for example, waste water with high organic content often contains some waste water with high organic content in industrial production, the index of COD (Chemical Oxygen Demand) is extremely high, and the conventional purification process is difficult to treat and has high cost. However, the coal water slurry gasification process just needs a large amount of water, and the coal water slurry is a liquid fuel synthesized by blending water and coal with additives, can absorb a large amount of organic wastewater generated in other processes, does not need additional pretreatment, and is an effective channel for consuming the organic wastewater.
The solid waste is classified according to the combustion heat value, the solid waste is firstly required to be capable of being combusted, and more toxic and harmful substances cannot be generated under the condition of direct combustion. Then, the solid waste can be classified according to the combustion heat value of the unit weight or volume of the solid waste, so as to distinguish the solid waste with different combustion heat values.
The solid waste is classified according to the carbon content, for example, waste rubber, waste plastic and waste tar contain more carbon and higher calorific value, are better fuels, can be used for combustion power generation in cooperation with a coal-fired boiler, but if the waste rubber, the waste plastic and the waste tar are only used as alternative fuels, the combustion power generation can only utilize the energy in the waste rubber, the waste plastic and the waste tar; because it contains higher carbon, which is a raw material for coking, waste rubber, waste tires, and waste tar should be preferentially used for coking under the same other conditions. The waste rubber and the waste tires can directly replace part of coking coal for coking, and the waste tar can participate in the preparation of coking coal briquette and serve as a binder. Coking makes the solid wastes carry out material resource utilization, and the added value of the solid wastes is greater than the energy utilization.
The solid waste is classified according to the types and the contents of metal elements, for example, iron oxide scales in iron and steel plants have high iron content and can be directly mixed into sintering for recycling. For another example, the steel process flow often generates more zinc-containing dust, and at present, part of the zinc-containing dust is directly mixed into the sintering raw material for synergistic treatment, in this case, zinc element in the solid waste is a harmful element for sintering, and more zinc element in the sintering ore affects the smooth operation of the blast furnace, so the proportion of the zinc-containing solid waste added in the sintering is usually limited. On the contrary, zinc is a resource in the colored industry, and if zinc-containing dust preferentially enters the colored industry, the influence of the zinc on the process flow can be eliminated, and the zinc in the zinc-containing dust can be recycled. Therefore, the zinc-containing dust generated in the steel process can be preferentially sent to the nonferrous industry for resource utilization.
It should be noted that, in the above process of classifying the solid waste, not limited to one classification method, in the actual use process, a plurality of classification methods may be used to perform cross classification, or under one classification principle, the solid waste may be further subdivided, for example, the waste rubber, waste plastic and waste tar may be used as the solid waste for combustion according to the classification principle of organic matters, and on the basis, the waste rubber, waste plastic and waste tar are classified according to the carbon content, so as to utilize the property that the waste rubber, waste plastic and waste tar can be coked. Step S204, obtaining the maximum receiving capacity of the first pre-selection disposal end, and marking the corresponding first pre-selection disposal end as a second pre-selection disposal end if the maximum receiving capacity is larger than or equal to the solid waste inventory of the solid waste end.
In practical application, generally, the disposal capacity of a single disposal end is far greater than the solid waste generation capacity of a single solid waste end, so only one disposal end is selected to be marked as a final disposal end, and the maximum receiving capacity of the disposal end serving as the second pre-selection end is required to be greater than or equal to the solid waste stock of the solid waste end.
It should be noted that, if the maximum receiving capacity of all the first pre-selection processing ends is smaller than the solid waste inventory of the solid waste ends in the actual screening process, it indicates that the solid waste treatment of the corresponding solid waste types in the area will reach the disposal limit in the current environment, and this situation is rare, and if the maximum receiving capacity reaches a certain value, the corresponding first pre-selection processing ends are marked as second pre-selection processing ends, and in the subsequent screening, a plurality of processing ends can be selected as the final processing ends, and the solid waste generated by the solid waste ends is received and disposed through the plurality of processing ends.
It should be noted that, in the practical application process, the first pre-selection processing end is not limited to be screened from the perspective of the maximum receiving capacity, and may also be considered from the perspective of the acceptable time, for example, in the specific implementation process, the transportation time is determined according to the disposal position of the first pre-selection processing end and the solid waste position of the solid waste end to be disposed; and determining the receivable time of the first pre-selected disposal end according to the disposal speed, the disposal inventory and the limit storage amount of the solid waste end to be disposed of the first pre-selected disposal end, and marking the first pre-selected disposal end corresponding to the receivable time as a second pre-selected disposal end if the receivable time is greater than the sum of the first time and the transportation time.
By ensuring that the receivable time of the second pre-selected disposal site is greater than the sum of the first time and the transport time, the residence time of the solid waste can be effectively avoided, for example, in avoiding long residence of the solid waste in a non-storage area of the solid waste site, the transport vehicle or the disposal site. It should be noted that, since the transportation of the solid waste is not completed instantaneously in the practical application process, and the acceptable capacity of the disposal end is in the dynamic change process, if further optimization of the overall scheme is considered, more specific dynamic update of the solid waste state can be considered, such as real-time solid waste stock of the solid waste end, real-time location of the solid waste transport vehicle, and real-time acceptable capacity of the disposal end.
It should be noted that, in the actual application process, since the solid wastes at the solid waste end are transported to the disposal end in batches, the solid wastes are not necessarily transported and processed until the solid waste inventory at the solid waste end reaches the limit storage amount, so in the actual application process, the step S204 may be replaced by: determining transportation time according to the disposal position of the first pre-selection disposal end and the solid waste position of the solid waste end to be disposed; determining the receivable time of the first pre-selection processing end according to the processing speed, the processing stock and the limit storage amount of the solid waste end to be processed of the first pre-selection processing end; and judging whether the receivable time is greater than the transportation time or not, and marking the first pre-selection handling end corresponding to the receivable time as a second pre-selection handling end if the receivable time is greater than the transportation time.
Step S205, determining the disposal cost of any second pre-selection disposal end according to the solid waste type, solid waste stock and solid waste position of the solid waste end to be disposed and the disposal position of the second pre-selection disposal end, comparing the disposal costs of all the second pre-selection disposal ends, and marking the second pre-selection disposal end with the minimum disposal cost as a final disposal end;
or,
determining the disposal energy consumption of any second pre-selection disposal end according to the solid waste type, solid waste stock and solid waste position of the solid waste end to be disposed and the disposal position of the second pre-selection disposal end, comparing the disposal energy consumption of all the second pre-selection disposal ends, and marking the second pre-selection disposal end with the minimum disposal cost as the final disposal end.
Fig. 3 is a schematic flow chart illustrating a process of determining disposal cost of any second preselected disposal terminal according to an embodiment of the present application; in step S205, the final disposal end is determined by optimizing the disposal cost, specifically, steps S301 to S303.
Step S301, according to the solid waste type of the solid waste end to be disposed, the unit disposal cost and the unit disposal benefit of the disposal end are obtained.
Step S302, determining the transportation distance between the solid waste end to be treated and the second pre-selection treatment end and the path cost coefficient corresponding to the transportation path according to the solid waste position of the solid waste end to be treated and the treatment position of the second pre-selection treatment end.
Step S303, determining disposal cost of any second pre-selection disposal end according to solid waste stock, unit disposal cost, unit disposal benefit, transportation distance of the solid waste end and a path cost coefficient corresponding to the transportation path.
Fig. 4 is a schematic flowchart of the process of determining the disposal energy consumption of any second pre-selected disposal node according to the embodiment of the present application. In step S205, optimizing the treatment energy consumption is performed to determine the final treatment end, specifically, steps S401 to S403.
Step S401, according to the solid waste type of the solid waste end to be disposed, unit disposal energy consumption and unit disposal capacity of the disposal end are obtained.
Step S402, determining the transportation distance between the solid waste end to be treated and the second pre-selection treatment end and the path energy consumption coefficient corresponding to the transportation path according to the solid waste position of the solid waste end to be treated and the treatment position of the second pre-selection treatment end.
Step S403, determining disposal energy consumption of any second pre-selection disposal end according to the solid waste stock, unit disposal energy consumption, unit disposal capacity, transportation distance and path cost coefficient corresponding to the transportation path of the solid waste end.
It should be noted that, in the present application, the final disposal end is determined by the disposal cost or the disposal energy consumption, but in the practical application process, the final disposal end is determined by optimizing the disposal cost or the disposal energy consumption, and other optimization criteria may also be adopted, for example, from the viewpoint of lowest environmental pollution, for example, from the viewpoint of shorter end time of solid waste disposal.
It should be noted that, in the embodiment of the present application, the layout is not limited to that the number of the solid waste ends to be disposed is one, when there are a plurality of solid waste ends to be disposed, different priorities may be set according to the condition of each solid waste end to be disposed, for example, the priority is determined by the type of the solid waste, or the priority is determined by the storage rate of the solid waste end, and the disposing ends corresponding to the solid waste ends to be disposed may be sequentially determined according to the order of the priorities.
It should be noted that, when there are a plurality of to-be-disposed-solid waste ends, the plurality of to-be-disposed-solid waste ends may be subjected to synchronous analysis processing without differentiating priority, and finally, the overall disposal scheme of the plurality of to-be-disposed-solid waste ends is determined, and then, the final disposal scheme is determined according to the disposal cost or the disposal energy consumption of the overall disposal scheme.
For example, the solid waste of the solid waste end a with the optimal cost is transported to a first disposal end for processing, the optimal disposal cost of the solid waste end a is 10 ten thousand yuan, the solid waste of the solid waste end a is transported to a second disposal end for processing, and the suboptimal disposal cost of the solid waste end a is 20 ten thousand yuan; the optimal solid waste disposal scheme of the solid waste end B is to transport the solid waste of the solid waste end B to the first disposal end for processing, but the optimal disposal cost of the solid waste end B is 8 ten thousand yuan, the suboptimal disposal scheme is to transport the solid waste of the solid waste end B to the second disposal end for processing, and the suboptimal disposal cost of the solid waste end B is 20 ten thousand yuan.
But the first disposal end can only receive the solid waste of one solid waste end; one overall treatment scheme is therefore: the first disposal end is used for disposing the solid waste of the solid waste end A, and the second disposal end is used for disposing the solid waste of the solid waste end B, so that the overall disposal cost is 30 ten thousand yuan; another overall treatment protocol is: the first disposal end is provided with solid waste of the solid waste end B, and the second disposal end is provided with solid waste of the solid waste end A, so that the overall disposal cost is 28 ten thousand yuan. By considering the optimal cost of the overall scheme and preferentially taking the second overall treatment scheme as the final treatment scheme, the situation that the scheme enters the scheme with the locally optimal treatment cost in the process of determining the treatment scheme can be effectively avoided, but the scheme is complex to process after the overall optimal scheme is adopted, and the scheme can be designed according to actual conditions in the process of practical application.
It should be noted that, in the practical application process, because the solid waste disposal processes are different, even one solid waste needs to go through multiple different disposal processes, so that the roles of the solid waste end and the disposal end are not always the same, and it is necessary to determine whether a certain factory or enterprise belongs to the solid waste end or the demand end according to the specific situation, for example, when a steel mill needs to receive solid waste with more iron-containing elements, the steel mill is the disposal end, but when slag generated by the steel mill needs to be disposed by other factories or deeply buried, the steel mill is the solid waste end.
