It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.

The cement kiln is an internationally accepted best means for disposing hazardous wastes, has the advantages of energy conservation, environmental protection, economy and the like, and has more than thirty years of safe operation experience in the cement industry of developed countries. Compared with other methods, the cement kiln for disposing hazardous wastes in a synergistic way has the following advantages:

(1) The investment is small, the process is mature, the cement kiln can cooperatively dispose the hazardous waste based on the existing cement plant equipment, and the equipment investment is small. The cement kiln is used for treating hazardous waste in a synergic manner, the treatment process is the same as that of a conventional incinerator, namely, high-temperature thermochemical reaction is carried out, and only the cement kiln is used for treating the hazardous waste in a synergic manner, so that the temperature in the cement kiln is higher, the heat capacity is larger, the waste retention time is longer, the hazardous waste is more completely combusted, the hazardous organic substance is incinerated under the high-temperature environment, and the generation of dioxin is avoided. Metal elements and the like after the dangerous waste is burnt can enter the cement clinkerIn addition, the alkaline environment of the cement kiln can also absorb acid gases generated in incineration, such as HCl and SO ₂ And the like, so as to realize the harmless treatment of the hazardous waste.

(2) And the secondary pollution is reduced. The rotary cement kiln system adopted during the treatment of the hazardous waste by the cement kiln is in a negative pressure state, so that the problem of overflow of pollutants such as smoke, dust and the like can be avoided in the combustion process, and the recontamination during the treatment of the hazardous waste is avoided. The cement factory is wide in area distribution, so that solid waste can be consumed on site, the transportation cost is saved, and the risk in the transportation process is avoided; meanwhile, the production scale of cement is large, and the amount of solid waste subjected to synergistic treatment is large.

(3) Promote the innovative development of cement enterprises. With the attention on environmental protection and energy conservation and consumption reduction in the whole society, cement enterprises also need to practice green development, save energy and reduce consumption. The cement kiln can replace partial fuel by various hazardous wastes in the cooperative disposal of the hazardous wastes, so that the energy consumption is reduced, the transformation of partial enterprises is facilitated, and the diversified development of cement enterprises and products is promoted.

The research and industrial test work of the cement kiln for cooperatively treating municipal domestic garbage, sludge and solid waste begins from the later 90 s in the last century in the cement industry in China. In 11 months in 2005, the Beijing cement factory processes 10 ten thousand tons/year industrial waste demonstration line and puts into production, and good beginning of utilizing cement kilns to cooperatively process waste in large scale is realized for the first time in the domestic cement industry. In recent years, the project of cooperative treatment of hazardous waste by using cement kilns in China has been in explosive growth. Data show that only 16 cement enterprises in China obtain hazardous waste operating licenses before 2015, and the qualification capacity of the cement kiln for cooperative disposal reaches 600 million tons as long as 2020 and 7 months, which relates to 111 cement production lines, accounts for 6.5% of the production lines, covers 27 provinces in China, and accounts for nearly 40% of the market. However, due to factors such as improvement of processing capacity and the like, the disposal price of hazardous waste in two years recently also shows a falling situation, and cement enterprises can obtain wrong-peak exemption rights in various ways after issuing emergency emission reduction technical guidelines (revised 2020) of important heavy pollution weather industry in the ecological environment part, so that a reasonable plan needs to be formulated according to market demands for predicting the project of cooperatively disposing hazardous waste in the cement kiln in the future cement industry.

Although cement kiln co-processing technology has obvious advantages and develops rapidly, certain environmental risks still exist, and treatment processes including transportation, storage, disposal and the like of hazardous wastes can cause pollution to the external environment to different degrees. Therefore, the research on the capability of the cement kiln to cooperatively dispose hazardous waste to generate secondary pollution is imperative. At present, a plurality of articles and periodicals in China enumerate and analyze the pollutant production capacity of partial flow of the cement kiln cooperative treatment of hazardous wastes, but because of the characteristics of long flow, complex process, multiple pollutant production links and the like, a method for comprehensively measuring the secondary pollution production of enterprises in a whole period flow of the cement kiln cooperative treatment of hazardous wastes is always lacked.

Therefore, the present application proposes an evaluation method for a cement kiln treatment waste complete cycle based on the characteristics of the cement kiln treatment process, as shown in fig. 1, the evaluation method comprises:

s101, obtaining disposal information of each disposal process in the whole cycle of the cement kiln for cooperatively disposing the hazardous waste; the cement kiln comprises a plurality of disposal processes in a complete cycle of the cooperative disposal of the hazardous waste, and the disposal information of each disposal process represents the disposal form, and/or the disposal result, and/or the disposal facility attribute of the cement kiln in at least one evaluation dimension of the disposal process;

s102, determining an evaluation value of an evaluation parameter on each evaluation dimension in each disposal process according to disposal information of each disposal process in the whole period of the cement kiln for cooperatively disposing the hazardous waste; each evaluation value represents an evaluation result on the evaluation dimension in the treatment process;

s103, determining an evaluation result of each treatment process according to the evaluation values of the evaluation parameters on all the evaluation dimensions in each treatment process.

And S104, determining the evaluation result of the cement kiln co-processing hazardous waste complete cycle according to the evaluation result of all processing processes in the cement kiln co-processing hazardous waste complete cycle.

In step S101, the disposal information of each disposal process characterizes a disposal form, and/or a disposal result, and/or a disposal facility attribute of the cement kiln in at least one evaluation dimension of the disposal process, including the following cases: characterizing a disposal pattern of the cement kiln in at least one evaluation dimension during the disposal; characterizing the disposal result of the cement kiln in at least one evaluation dimension during the disposal process; characterizing disposal facility attributes of the cement kiln in at least one evaluation dimension during the disposal process; characterizing a disposal form and a disposal result of the cement kiln in at least one evaluation dimension during the disposal process; characterizing disposal results and disposal facility attributes of the cement kiln in at least one evaluation dimension during the disposal process; the method includes characterizing a disposal form and disposal facility attributes of the cement kiln in at least one evaluation dimension during the disposal process.

As shown in fig. 2, in step S101, the multiple disposal processes included in the whole cycle of the cement kiln co-disposal of the hazardous waste are obtained by dividing the whole cycle process according to different treatment modes for the hazardous waste in the whole cycle process of the cement kiln co-disposal of the hazardous waste; the plurality of disposal processes included in the cement kiln co-disposing the full cycle of hazardous waste include at least one of: the method comprises the following steps of a storage process, an in-plant transportation process, a pretreatment process, a cooperative treatment tail end treatment process, a product detection process and a monitoring management process.

The evaluation dimension in each disposal process is determined according to the reason of secondary pollution caused in the disposal process when the hazardous waste is cooperatively disposed by the cement kiln in the disposal process;

The evaluation dimension in each disposal process is determined according to the reason of secondary pollution caused in the disposal process when the cement kiln in the disposal process is used for cooperatively disposing the hazardous waste, wherein the hazardous waste causes the secondary pollution, and the evaluation dimension does not cause the secondary pollution or definitely causes the secondary pollution, but means that the possibility of causing the secondary pollution exists.

In step S102, the evaluation value of the evaluation parameter in each evaluation dimension in each treatment process may be a corresponding parameter value that can be acquired or measured in the evaluation dimension, that is, may be quantized data; for treatment modes, treatment facility attributes and the like which cannot be quantified in the evaluation dimension, scoring can be performed according to effect differences among treatment facilities of different treatment forms or different attributes to obtain evaluation values of evaluation parameters.

Each evaluation value represents an evaluation result on the evaluation dimension in the treatment process, the evaluation result may be directly the evaluation value of the evaluation parameter, or a rating may be attached, and the rating may be: good, general, and unqualified, each level corresponding to a value range of the evaluation value of the evaluation parameter.

In step S103, the evaluation result of each treatment process may be an evaluation value of the evaluation parameter in all evaluation dimensions of the treatment process, a rating in all evaluation dimensions, an excellent rate, a qualified rate, and the like obtained according to the rating in all evaluation dimensions.

In step S104, the evaluation result of the cement kiln in cooperation with the disposal of the hazardous waste in the whole cycle may be an evaluation result in each disposal process, an evaluation value of an evaluation parameter in each evaluation dimension in each disposal process, a rating in each evaluation dimension in each disposal process, an excellence rate and a qualification rate in each disposal process, or an excellence rate and a qualification rate in the whole cycle obtained according to the rating in each evaluation dimension in each disposal process.

Furthermore, each disposal process corresponds to a different treatment mode and/or treatment flow of the hazardous waste, and one evaluation dimension in the disposal process corresponds to one cause or pollution production link causing secondary pollution, so that the hierarchical evaluation method is more scientific and reasonable.

In some embodiments, the disposal information of each disposal process characterizes the disposal form, and/or the disposal result, and/or the disposal facility attribute of the cement kiln in at least one evaluation dimension of the disposal process; the treatment facility attribute specifically includes a parameter value of the treatment facility attribute of the cement kiln in at least one evaluation dimension, and the treatment result of the treatment process specifically includes a parameter value of a secondary pollutant or a monitoring result corresponding to the treatment result of the cement kiln in at least one evaluation dimension, so as to quantify the treatment result or the treatment facility attribute of the treatment process through the parameter value.

In some embodiments, the cement kiln has parameter values for treatment facility attributes in at least one evaluation dimension, the evaluation dimension specifically comprising: in the storage process, the seepage-proofing coefficient of the storage facility under the seepage-proofing evaluation dimension of the storage facility;

in the product detection process, under the evaluation dimension of the heavy metal hazard level, the content of leachable heavy metals in cement clinker output by the cement kiln is reduced; and under the waste gas treatment evaluation dimension of the clinker silo, the emission concentration of particulate matters in the atmospheric pollutants of the exhaust funnel of the clinker silo.

In some embodiments, the secondary pollutant parameter value corresponding to the disposal result of the cement kiln in the disposal process further includes: in the monitoring and management process, the number of the operation systems established by enterprises under the comprehensive monitoring and evaluation dimensionality of the operation systems.

In the evaluation dimension of the disposal process, the disposal information is a disposal result or a parameter value corresponding to a disposal facility, and the evaluation of the effect of preventing secondary pollution of the cement kiln co-disposed hazardous waste in the corresponding evaluation dimension of the corresponding disposal process is quantitative evaluation, so that the evaluation method is more objective.

In order to further improve the accuracy of the disposal result or the parameter value corresponding to the disposal facility and evaluate the pollutant generation link in the disposal process of the cement kiln for cooperatively disposing the hazardous waste more objectively and accurately, the parameter value of the secondary pollutant corresponding to the disposal result of the cement kiln in the disposal process is the online monitoring average value of the secondary pollutant in a preset time period; the method specifically comprises at least one of the following steps:

under the evaluation dimension of kiln tail flue gas treatment, the concentration of various pollutants in the kiln tail chimney atmospheric pollutants is an on-line monitoring average value of the kiln tail chimney atmospheric pollutants in a preset time period:

under the evaluation dimension of the bypass air-bleeding flue gas treatment, the concentration of various pollutants in the air pollutants of the bypass air-bleeding exhaust funnel is the average value of the on-line monitoring of the air pollutants of the bypass air-bleeding exhaust funnel in a preset time period.

In the process of disposing hazardous waste in cooperation with the cement kiln, the disposal form of the hazardous waste also has great influence on the pollution prevention and control effect, the more advanced and scientific the disposal form is, the better the pollution prevention and control effect is, otherwise, the worse the pollution prevention and control effect is. However, the disposal forms are difficult to be completely quantified, so that the pollution prevention and control effects corresponding to different disposal forms are graded according to analysis and investigation of a typical cement kiln, and grading is performed by referring to grading results to realize quantification to a certain extent, so that the prevention and control effects of the cement kiln in cooperation with the whole period of disposal of hazardous wastes are scientifically evaluated.

Specifically, in the evaluation method for the cement kiln waste disposal complete cycle, the disposal information of the disposal process represents a disposal form of the cement kiln in at least one evaluation dimension of the disposal process, and the disposal form specifically includes:

during storage, the storage form is evaluated for storage form in dimension;

and in the pretreatment process, the pretreatment waste gas treatment evaluation dimension is used for pretreating the waste gas treatment form.

In the following, classification on each evaluation dimension in each disposal process, parameter values corresponding to the quantifiable evaluation dimensions, and evaluation parameters corresponding to each evaluation dimension are specifically described in combination with relevant information of a whole-cycle flow, each disposal process in a whole cycle, and the evaluation dimension of each disposal process for cooperatively disposing hazardous wastes by a cement kiln.

The storage process mainly refers to a treatment stage of storing hazardous wastes such as tailing slag, smelting slag and the like in a storage facility, and in the treatment stage, the hazardous wastes are stored.

The secondary pollution caused by hazardous waste during storage is mainly caused by: the seepage-proofing effect of the storage facility is poor, so that secondary pollutants are leaked out, the storage form is improper, so that different kinds of hazardous wastes are mixed and react, and the treatment effect of the percolate is poor, so that secondary pollution is caused. Thus, the evaluation dimension of the storage process comprises at least one of: seepage prevention of storage facilities, storage form and leachate treatment.

Specifically, under the evaluation dimension of the seepage prevention of the storage facility, the seepage prevention of the bottom and the side wall of the storage facility is required to meet the relevant requirements of the hazardous waste storage pollution control standard (GB 18597). And according to the anti-seepage effect, the method is divided into 4 grades, namely good (the anti-seepage coefficient is superior to 10-12cm/s, an anti-seepage leakage detecting system is provided, or the anti-seepage coefficient is superior to 10-12cm/s, no anti-seepage leakage detecting system is provided), good (the anti-seepage coefficient is superior to 10-10cm/s, no anti-seepage leakage detecting system is provided), normal (the anti-seepage coefficient is superior to 10-10cm/s, no anti-seepage leakage detecting system is provided), and unqualified (the anti-seepage coefficient is not more than 10-10 cm/s). I.e. the disposal information of the storage process characterizes the disposal facility properties in the evaluation dimension of storage facility impermeability. The seepage-proofing evaluation parameter of the storage facility can be a seepage-proofing coefficient, and can also be a value corresponding to a seepage-proofing effect obtained by combining the seepage-proofing coefficient with a non-seepage-proofing leak detection system, and the effect can be determined by referring to the grading.

Under the evaluation dimension of the storage form, the facility for storing the hazardous waste is required to be specially constructed and meets the relevant requirements of the pollution control standard for storing the hazardous waste (GB 18597), and the hazardous waste is ensured not to be stored in a mixed way with cement production raw materials, fuels and products. And according to the storage form, the method is divided into 5 grades, namely good (each dangerous waste is stored in a subarea mode, the field is standardized), good (each dangerous waste is stored in a subarea mode, the field is under-standardized), general (different dangerous wastes which have similar properties and can not react, mixed storage and the field is standardized), poor (different dangerous wastes which have similar properties and can not react, mixed storage and field disorder), unqualified (different dangerous wastes which can react, mixed storage and field disorder). I.e. the disposition information of the storage process, also characterizes the disposition form in the evaluation dimension of the storage form. The storage form evaluation parameter may be a score obtained according to the effects corresponding to the different storage forms, which can be determined with reference to the above-described ranking.

Under the evaluation dimension of the treatment of the percolate, the percolate can be required to be treated by spraying into a cement kiln for incineration, conveyed to an urban sewage treatment plant for treatment by closed transportation, discharged into an urban drainage pipeline for treatment, treated by self, and the like, and the wastewater discharge is required to meet the requirements of the national relevant water pollutant discharge standard. And according to the treatment form of the percolate, the percolate is divided into 4 grades, namely good grade (all is sprayed into a cement kiln for incineration treatment or the percolate enters a raw material mill along with the raw material for controlling the water content), good grade (part is sprayed into the cement kiln for incineration treatment or the percolate enters the raw material mill along with the raw material for controlling the water content, and part is treated and then discharged after reaching the standard), general grade (all is treated and discharged after reaching the standard), and unqualified grade (discharge exceeding the standard). The raw materials are completely sprayed into a cement kiln for incineration disposal or are fed into a raw material mill along with the raw materials for controlling the water content, namely no leachate is generated in the storage process. The treatment information of the storage process also represents the treatment form under the evaluation dimension of the leachate treatment, and leachate treatment evaluation parameters can be scores obtained for the effects corresponding to different leachate treatment modes, and the effects can be determined by referring to the grading.

The on-site transportation process is a process of transporting hazardous wastes in an enterprise site, and the reasons for secondary pollution in the on-site transportation process are as follows: dust emission, spillage and leakage during transportation of hazardous waste; cleaning pollutants in vehicle cleaning wastewater obtained by cleaning a transport vehicle; the wastewater produced during the vehicle cleaning process treats contaminants in the sludge.

Thus, the evaluation dimension of the in-plant transportation process includes at least one of: transportation form, vehicle cleaning wastewater, wastewater treatment sludge.

The transportation form evaluates the dimension and requires that necessary measures should be taken to prevent flying dust, spillage and leakage of hazardous waste when the hazardous waste is transported in a factory. And is divided into according to the transportation form: good (hazardous waste is homogenized and then is transported and fed through a closed pipeline), general (vehicle closed transportation and closed feeding) and unqualified (vehicle unsealed transportation and unsealed feeding) are graded by 3 grades. The transportation form evaluation parameter may be a score value according to the effect of preventing secondary pollution of different transportation forms, which can be determined with reference to the above-described grades.

The dimension evaluation of the vehicle cleaning wastewater requires that the vehicle cleaning wastewater can be treated by spraying into a cement kiln for incineration, is conveyed to a municipal sewage treatment plant for treatment by closed transportation, is discharged into a municipal drainage pipeline to enter the municipal sewage treatment plant for treatment, is treated by self, and the like, and the wastewater discharge meets the requirements of the national relevant water pollutant discharge standard. And according to the treatment form of the vehicle cleaning wastewater, the treatment method comprises the steps of completely spraying cement kiln for incineration treatment or controlling the water content to enter the raw material mill along with the raw material, better (partially spraying cement kiln for incineration treatment or controlling the water content to enter the raw material mill along with the raw material, and discharging part of the water content after treatment to reach the standard), generally (discharging the water content after reaching the standard after being completely treated), and unqualified (discharging the water content outside exceeding the standard) by 4 grades. The vehicle washing wastewater evaluation parameter may be a score corresponding to an effect of preventing secondary pollution corresponding to different vehicle washing wastewater treatment forms, and the effect may be determined with reference to the above-described classification.
