  The present invention relates to a dynamic screening method for an operating factory process.

Industrial pollution means that exhaust, wastewater, and solid emissions formed during industrial production cause environmental pollution, and industrial pollution is one of the main sources of environmental pollution. There are risks in many processes in the factory that are in operation, and the continuous or gradual operation of the process causes environmental pollution and affects people's health.
Also, since resources are finite, the most effective method is to screen operating factories with high risk in the process and control those active factories with high risk in the process. Is the method.

  The screening method for an operating factory that has a high risk in the process is conventionally evaluated based on the factory registration data, and then the evaluation result of each factory process is created, and the process potential of each factory is Create a priority survey list based on risk assessment results. The priority survey list includes a list of active factories with high risk of contamination and is used for subsequent surveys and controls.

However, there are many deficiencies and typographical errors in the early factory process data, and the factory process data changes depending on factors such as economic trends, industry dynamics, environmental protection laws, etc. Determining the risk level of an operating factory process based solely on the actual risk of a continuous or gradual process of an operating factory is difficult to reveal and difficult to judge.
For this reason, in the conventional method, it takes too much manpower and cost to control an operating factory that is large in quantity and lacks records and data, and the physical and cost has increased.

It is a flowchart which shows preferable embodiment of this invention.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments described below.

(First embodiment)
FIG. 1 illustrates a dynamic screening method for an operating factory process according to an embodiment of the present invention. Mainly the preparation step 10, the first level evaluation step 20, the second level evaluation step 30, the third level evaluation step 40, the fourth level evaluation step 50, the correction evaluation step 60, and the sorted list Evaluation step 70, and further includes the following steps.
(1) In the preparation step 10, risk data of the process of each operating factory for each industry is provided. In the present embodiment, the preparation step 10 further includes basic data for which registration is applied for each operating factory for each industry, and the process risk data further includes at least process parameter data.

By the way, the use, production, storage, and disposal of raw materials are affected by the business conditions of the industry, the management of the manufacturer's own production process, and the difference in the yearly change due to the company strategy such as factory expansion. Collect contamination items of industrial site data (including age, aging, application considerations, eg differences in the use and dose of each compound used in the process in each industry sector); In addition, data including missing age is acquired.
For example, in the database search scope, it is not possible to search retrospectively for places where organic solvents containing chlorine were used early, especially in industries with high potential pollution levels where organic solvents containing chlorine were used early. It may not be currently used.

In terms of organic compounds containing chlorine, the distribution and degradation conditions in different surrounding media differ due to multiple physical, chemical and biological properties such as adsorption, volatilization, dissolution, transformation and transfer. Occurs. Inspection data of environmental pollutants is used for analysis of distribution to the environment, and its significance is read.
For example, if only the declaration record items in the region are calculated by considering the feedback of the verification rate of the compound, and the result of the survey accurately results in the analysis of the feedback, the error due to the deterioration mechanism is eliminated.

In the first level evaluation step 20, high-risk target compounds to be noticed are selected based on the process risk data provided from each operating factory. In this embodiment, an embodiment will be described in which a target compound to be noted is a compound containing chlorine.
The filtering of the target compound to be noted in the first level evaluation step 20 is selected based on a plurality of evaluation factors, which are vertical movement characteristics, the risk of contamination of groundwater, the high risk of carcinogenesis, and the contamination. It includes the appearance rate of the ground, the acquisition rate of the previous plan, and the reaction generation route of the target compound to be noted. For example, it is shown in Table 1 below.

Note the following:
1. Refer to the National Cancer Institute (IRIS) for carcinogens, and common reaction generation pathways are McCarty and Emprini (1994) and Vogel et al. (1987), carcinogen settings are modified based on regional differences.
The numerical value of specific gravity / viscosity of 2,1,1,2-trichloroethane is clearly higher than other contaminants.
3. Solubility of dichloromethane and 1,2-dichloroethane / groundwater control standard values are clearly higher than other pollutants.
4. Chloroethylene has been determined to be a carcinogen by IARC and IRIS.
5. Of the 1444 areas surveyed by ATSDR, trichlorethylene and perchlorethylene were found in 391 and 309 areas, respectively, which were significantly higher than other pollutants, and 1.1-dichloroethane was groundwater in this embodiment. Because the control standards are so lenient, it is difficult to acquire, and standards are set according to demand for this part.
6. Evaluate the possibility of accumulation of notable compounds by taking into account the generation and degradation environment pathways of compound reactions. Taking the path of dechlorination degradation of organic substances containing chlorine as an example, for example, chloroethylenes VC are 0 points, cis-1,2-DCE is 1 point, and TCE and PCE are 2 minutes.
7. The detection rate is calculated for those detected in the plan of the previous four seasons and declared in the poison management database. If the detection rate is 0, 0 points, if it is 50% or less, 1 point, if 51% or more The score is also calculated when the number of areas in the reporting area exceeds 10 or the number of areas exceeding the standard is 5 or more.
8. Code “ ^V ”: Include, Code “O”: Control of non-toxic chemical substances, and adjustment of auxiliary filtering by industry.

  By the way, based on the survey results, the data of the front-end of the initial filtering is accurately fed back and examined to examine the sort and importance of the target compound evaluation factors for each period. That is, when the dynamic screening method of the factory process that is operating every time is performed, the quantity of the target compound to be noticed does not completely coincide with each other. I do.

(2) In the second level evaluation step 30, based on the risk data of the process provided from each operating factory, an industry with a high potential pollution level is selected.
In the present embodiment, the industry-specific filtering in the second level evaluation step 30 refers to the business statistics source data of the domestic correlated industry compared to the foreign industry and the domestic pollution notification place. In addition, data by industry in the controlled areas of the country is also collected, and the distribution status by industry with high potential pollution operating in the country is revealed.

By the way, related statistical data of organic solvent regulated areas containing foreign chlorine are shown in Kueper et al. (2003) organizes industrial and industrial processes in underground environments that are easily contaminated by organic solvents containing chlorine. More than half of machinery and metal manufacturing processing related, so it is a reference for filtering by industry.
Tables 3 and 4 below show the main uses of these organic solvents containing chlorine and the ratios of the compounds used in these uses. For example, perchlorethylene (PCE) accounts for 56% of dry cleaning applications, and trichlorethylene (TCE) accounts for 44% of degreasing applications, which means that the discovery rate in the underground environment survey process is generally high. To do.
Table 4 below shows a comparison of pollution patterns at domestic and overseas factories. There are many similarities in the industries to which control factories in which soil and groundwater are contaminated by using organic solvents containing chlorine, and they are included in industries that should be noted with priority.

In addition, the industry-specific registration data includes the status of the diversity of factories in the factory, so whether to correct the industry-specific feedback to be added to the evaluation results of the initial results (early operating status, current actual operating status). Situations, on-site review and inspection of the process mode of operation of compounds containing chlorine), and discuss after determining the main process industries to be adapted.
In the present invention, the business type indicated by the factory process is acquired by performing on-site verification and acquiring correlated data of the factory (for example, analysis and evaluation of the conceptual form of the feature of contamination). The quality of data fed back is ensured by this method.

(3) In the third level evaluation process 40, a level cross-filter is performed based on the reported amount of the target compound to be noted and the scale data for each industry, a preliminary survey list is created, and priorities are assigned. The basis for environmental site assessment of the factory inside.
In the present embodiment, in the third level evaluation step 40, the scale data includes the total classification for each type of industry with a high degree of potential pollution, the sorting of the total amount of reports for each type of industry with a high degree of potential pollution, and the target compound to be noted. Cross-sorting is performed based on the evaluation factors such as the total classification of declarations, the comprehensive classification of target compounds to be noticed, the presence or absence of release, wet process, installation age, and inspection disposal data.

  (4) In the fourth level evaluation process 50, the initial evaluation results and the local experience data are provided based on the preliminary survey list, the survey list is created, and the working factory is investigated and verified with priorities. As a basis. In the present embodiment, in the fourth level evaluation step 50, the initial evaluation result takes into account the factory operation history, the characteristics of the manufacturing process, and the hydrological conditions of the region based on the strict initial evaluation result for the region. The initial assessment further considers the application of subsequent multiple survey techniques in the region, the distribution of locations suitable for sampling of highly contaminated soil and groundwater is determined, and the results of the survey and verification are comprehensively considered At the same time, considering the specific gravity of the survey of factories by industry with high potential pollution level, a survey list is created.

  Regional experience data is combined with long-term research experience of local environmental protection agencies, and the transition of the jurisdiction and hearing of pollution information become the source of information for providing filtering data. A list of high-potential factories in the jurisdiction (for example, if the potential pollution around a monitoring well in an industrial area is high, the factory is the source of pollution. Suspicious) is provided as a designated survey list. This mechanism allows local residents to file a petition with the local Environmental Protection Agency, where they are added to the survey list, filtered, and inspected underground factories. Thereby, it is referred as regional experience data, and the order of the survey list is adjusted.

  Regional experience data further includes process operational data and location sensitivity data.Process operational data has a higher priority as the factory is established earlier, and is more important than industrial process operational characteristics and wet process facilities. At the same time, comparisons of areas prone to soil and water contamination problems during the operation of organic solvent processes containing chlorine at home and abroad, related surveys and fine data collected and filtered factories are similar It is evaluated whether or not it includes a potential pollution area, and the order of the list is adjusted according to the priority of the investigation. The location sensitivity data is preferentially filtered in the vicinity of the water source protected area, the vicinity of the irrigated farmland, the normal groundwater, and the area with high population density, and the order of the list is adjusted according to the priority of the survey.

(5) In the correction evaluation step 60, on-site verification is performed based on the survey list, the importance of the target compound to be noted in the first level evaluation step 20 based on the actual survey results, and in the second level evaluation step 30 The importance of each type of industry having a high degree of potential pollution, the importance of environmental site assessment in the third level evaluation process 40, and the order of the survey list in the fourth level evaluation process 50 are adjusted.
In the present embodiment, in the correction evaluation step 60, the actual survey results include the reported total amount of pollutant items, consideration of the product life cycle, consideration of the size and ratio of the reported total amount of factory processes in operation by industry, Includes process operating characteristics and installation age.

  (6) In the evaluation sort list 70, based on the importance of the first level evaluation step 20 to the fourth level evaluation step 50 corrected in the correction evaluation step 60, a newly sorted field verification investigation list is acquired. The

  Therefore, the screening mechanism of the dynamic screening method of the factory process in operation according to the present invention is adjusted for the level and importance of filtering elements with reference to the previous research results, and lessons learned from experience (Lesson Leamed) Is obtained. By adjusting the constant results of each period, the acquisition rate of each period is maintained at 60% or more, which indicates that adjustment and correction are important for the filtering mechanism of each period. With constant adjustment, potential features are also re-arranged constantly, a phenomenon that overturns the perception of field verification of traditional list sorting (following the previous factory list rank).

Re-sorting of potential pollution finds different challenges in the filtering strategy for each period. For example, in the first period, two filtering main axes (factories around monitoring wells exceeding control standards, those with a large total amount of declarations) Investigate first. In the second period, the one with a large total amount of declarations is the main axis of filtering, and it is included in the consideration of the potential of each industry. Reach).
In the third period, sorting of high-potential industries, target compounds, etc. will be adjusted, and filtering of factories with high potential pollution will be strengthened. In the third period, the list of factories will be larger than in the second period (22 Reach 2%). In the 4th period, the mechanism of the 3rd period will be continued, and in the 4th period, the fluctuation range of the factory list will be larger than that in the 3rd period (47.9% will be reached).
In the 5th period, the characteristics of “excessive operation history” were added. For example, (1) Declared early, but now it is not used. It is verified again whether it is contaminated, and the 5th period shows that the fluctuation of the factory list is not larger than that in the 4th period (reach 10.2%), indicating that the filtering mechanism is gradually becoming loose.

  In conclusion, the dynamic screening method of the working factory process according to the present invention creates a systematic evaluation result in accordance with the actual situation of the working factory in the industrial system, so that the working factory process To ensure the effectiveness of the risk level assessment of the plant and to make the subsequent inspection and control of the operating plant more efficient.
