Main data and sub-data necessary for selecting a method for purifying soil contamination in the target area and calculating a purification cost are input to the input unit 1. In addition, the soil contamination here includes the contamination of water such as groundwater. The input unit 1 is, for example, a keyboard. The input means 1 is connected to the arithmetic means 2, and the main data and the sub data input to the input means 1 are sent to the arithmetic means 2, where the arithmetic processing is performed, and the soil contamination at the target site is reduced. The method of purification is selected and the cost of purification is calculated. The arithmetic means 2 is, for example, a CPU (central processing unit) built in a computer
It is.

The calculating means 2 has a database 3 in which information necessary for selecting a purification method and calculating a purification cost is stored.
Is connected. The database 3 contains, for all purification method candidates, a list of substances that can be processed by each purification method, a list of targets (geological conditions), a list of location conditions of purification sites, and a concentration method of a pollutant. A data group relating to main data necessary for selection and a data group of purification cost coefficients corresponding to values of respective items of main data and sub data are stored. Here, the purification cost coefficient is a cost ratio to a standard unit price per unit area. Instead of the purification cost coefficient, the unit price of the purification cost per unit area under the condition of each item may be stored. The database 3 is, for example, a storage device such as a hard disk built in a computer.
The calculating means 2 selects a purification method and calculates a purification cost while referring to the information stored in the database 3.

The calculating means 2 is also connected to the output means 4. The output means 4 is, for example, a CRT (Cathode-Ray Tube; cathode ray tube, cathode ray tube) connected to a computer
And the like. The purification method selected by the calculating means 2 and the calculated purification cost are as follows:
It is sent to the output means 4, and the output means 4 outputs the selected purification method and the calculated purification cost sent from the arithmetic means 2. If the output means 4 is, for example, a display device,
This display device displays the selected purification method and the calculated purification cost.

Next, with reference to FIG. 2, a procedure for selecting a purification method for purifying soil contamination of a target area and calculating a purification cost using the soil contamination purification cost calculation system according to the present embodiment will be described.

First, a person who intends to select a purification method and calculate a purification cost (a user of this system) collects main data and sub-data to be input to the soil pollution purification cost calculation system.

The main data includes the geological data of the target area obtained from the survey results, the types and concentrations of pollutants contained in soil and groundwater, the area of the contaminated area, the depth of the contaminated area, and the amount of water used for purification. Of the work space that can be used for purification work, the distance between the purification work space and the contaminated area, the presence or absence of buildings in the contaminated area, the expected amount of groundwater and groundwater It contains data on each item such as the direction in which the flows. Main data can be collected by conducting surveys in a manner consistent with the guidelines of the Environment Agency.

The sub-data includes information on whether or not there are ordinances / outline by the local government in charge of the target area, whether or not the local residents have wells, the dependency on groundwater (water supply diffusion rate), and the establishment of councils or liaison meetings by local residents. Includes data on each item such as presence / absence, pumping restrictions, and the concentration of pollutants in groundwater in the target area. Here, "target area" in the item "concentration of pollutants contained in groundwater in the target area" refers to an area larger than the land (target land) for which purification methods are selected and purification costs are calculated. That is, it refers to the entire area including the target area. The groundwater concentration in the target area has been published. In addition, the existence of regulations ordinances, the ratio of groundwater dependence, and the presence or absence of pumping regulations are published for each local government where the target area is located. However, since there is no published data on the presence or absence of a well and the council of residents, it is necessary to collect information by hearing.

The user inputs the collected main data and sub data to the input means 1 of the soil pollution remediation cost calculation system. For the input, there is a method of directly inputting the information collection result via a keyboard or the like. However, it is preferable to be able to selectively input the result in a menu format or the like because operability is improved. The main data and sub data input to the input means 1 are sent to the arithmetic means 2,
Here, arithmetic processing is performed. In this arithmetic processing, data on each item of the main data is digitized. The sub data is used for weighting each item of the main data.

The calculation means 2 performs calculation processing, that is, selection of a purification method and calculation of a purification cost, with reference to the information stored in the database 3. The database 3 contains past purification results, data on the applicable range of each purification method,
It stores government-owned materials including the groundwater dependency ratio, various data obtained through interviews, unit price tables showing the costs required to implement each purification method, and the like.

The arithmetic means 2 extracts a purification method candidate that can be implemented in the target area using the main data and the sub-data while referring to the information stored in the database 3, and Among them, select a purification method suitable for the target area. The purification method selected may be multiple. Next, the calculating means 2 calculates the purification cost for each selected purification method using the main data and the sub data while referring to the information stored in the database 3. The purification cost is calculated by multiplying the unit price per unit size determined for each purification method by the data on the pollution scale given from the main data. Note that, when a plurality of purification methods are selected, the calculation means 2 calculates the purification cost based on the purification cost calculated for each purification method.
Prioritize purification methods.

The purification method selected by the arithmetic means 2 and the calculated purification cost are sent to the output means 4, and are output to the output means 4.
Outputs the selected purification method and the calculated purification cost sent from the arithmetic means 2. If the output means 4 is a display device, the display means displays the selected purification method and the calculated purification cost. As described above, since there are a plurality of selected purification methods, the purification methods output by the output unit 4 are also the plan A, the plan B, and the plan shown in FIG.
As in the C plan, there may be more than one. These alternatives are prioritized.

Further, in one plan, for example, plan A, a plurality of purification methods may be mentioned. In the illustrated example, the target area is divided into area 1, area 2, and area 3,
Different purification methods are selected for each area.

Next, an example of a procedure for selecting a purification method based on main data and sub data will be described with reference to FIG. FIG. 3 is a table created by the arithmetic means 2 with reference to the database 3 based on the input information (that is, main data and sub-data), and is a table showing the correspondence between each purification method and each item of the input information. FIG. 3 shows that the input information of the main data is “substance name = trichloroethylene”, “subject =
The example is a case where “soil”, “location condition = under a building”, and “concentration = 5000 times or more of environmental standard value”. The vertical direction of the table lists each purification method, and the horizontal direction lists main data and sub data items.

The operation means 2 refers to the database 3 to mark the "substance name" item in the purification method candidates that can process "trichloroethylene", and to perform purification for "soil". "Target" in method candidates
Is marked, and a mark is given to the item of "location conditions" in the purification method candidates that can purify "under the building", and the purification that can be processed "5000 times or more of the environmental standard value" The table is created by adding a mark to the item of “density” in the method candidate. By searching for purification methods in which all items in the table are marked (black circles),
It can be seen that purification methods applicable to the input information can be narrowed down.

In the sub-data, if there is a pumping regulation, the pumping volatilization processing (× in the table)
Mark) cannot be selected.

The groundwater contamination concentration of the “target area (entire area)” in the sub-data (“the concentration value of the target area” in the table) is the same as the groundwater contamination concentration of the “target area” in the main data (“the concentration value of the table”). Density value)),
No purification method is selected. That is, in such a case, it is determined that it is not necessary to take a countermeasure against groundwater contamination in the target site.

Next, an example of a procedure for assigning priorities (priorities) to purification methods based on the information and sub-data stored in the database 3 will be described with reference to FIG. FIG. 4 shows that the calculating means 2 uses the database 3 based on the input information (ie, main data and sub data).
Is a table created with reference to the table, showing the relationship between each purification method and the purification cost coefficient corresponding to the value of each item of the input information. FIG. 3 shows an example in which the input information of the main data is “substance name = trichloroethylene”, “target = soil”, “location condition = under a building”, and “concentration = 5000 times or more of the environmental standard value”. . For example, the cost coefficients of the sub-data “geological data” in the “high vacuum extraction” purification method of the database 3 include “sand quality = 1.0” and “silt =
A data group of “1.2” and “clay = 1.5” is stored, and a numerical value of 1.0 is assigned to a corresponding column based on “sand” which is input information in this example. The table is created by performing the same processing as in the numerical value assignment for each item. The vertical direction of the table lists each purification method, and the horizontal direction lists main data and sub data items.

For example, as a purification method, "high vacuum extraction"
And "in-situ oxidative decomposition treatment", the purification cost coefficient a according to the purification cost per unit volume and the purification cost coefficient b according to the maximum concentration of the pollutant in each purification method. And a purification cost coefficient c corresponding to the geological data, a purification cost coefficient d corresponding to whether the flow rate of the groundwater is high, and a purification cost coefficient e corresponding to whether the administrative guidance in the target area is severe. (Ie, a × b × c × d × e is calculated), and the result is used as an evaluation result, and a priority (priority) is assigned based on the evaluation result. More specifically, a higher priority is assigned to a lower value of the calculated evaluation results a × b × c × d × e.
