Description

  The present invention relates to an operation management system and an operation management method for a groundwater purification treatment apparatus.

  In recent years, the demand for groundwater has increased as a source of water that is not affected by disasters and weather. In general, groundwater pumped from the ground contains impurities such as iron, manganese, and ammonia. When using the groundwater, the groundwater is subjected to purification treatment to remove or remove these impurities. There is a need to reduce. For this reason, various methods and devices for purifying groundwater have been proposed (for example, see Patent Document 1). As an example, the groundwater purification treatment apparatus 14 shown in FIG. 15 excavates a deep well of about 100 m, pumps up groundwater in a confined aquifer (compressed groundwater), and provides microbiological hygiene with a membrane filtration device. After securing and sterilizing chlorine, water is supplied.

  Specifically, in the groundwater purification treatment apparatus 14, groundwater is pumped from the well 16 by the well pump 50 and is temporarily stored in the raw water tank 52 as treated water 54. Sodium hypochlorite is added to the treated water 54 in the raw water tank 52 from a sodium hypochlorite storage tank 56 via a sodium hypochlorite supply pump 58. And the to-be-treated water 54 in the raw water tank 52 is aerated by the blower 60, and iron and manganese contained in the to-be-treated water 54 are insoluble due to the aeration effect and the oxidation effect of sodium hypochlorite. It becomes a solid compound and ammonia nitrogen is removed after generating nitrogen gas by discontinuous point chlorination. Thereafter, the water to be treated 54 in the raw water tank 52 is pumped by the raw water pump 62 and filtered by the sand filtration tower 64 to further remove impurities in the water to be treated 54. Subsequently, the treated water 54 is passed through the activated carbon tower 66, and after removing residual chlorine in the treated water 54, sodium hypochlorite so that the treated water 54 has a predetermined residual chlorine concentration. Sodium hypochlorite is again added from the storage tank 56 via the sodium hypochlorite supply pump 68. And the to-be-processed water 54 is filtered with the filter membrane 70 comprised by a microfiltration membrane, an ultrafiltration membrane, etc., and after removing microorganisms, bacteria, etc. which are contained in the to-be-processed water 54, in the treated water tank 72 Store.

By the way, in the groundwater purification treatment apparatus 14 of FIG. 15, groundwater pumping from the well 16 is performed based on the water level of the treated water 54 stored in the raw water tank 52, and When the treated water 54 reaches a low water level, operations such as operating the well pump 50 have been performed. On the other hand, considering the amount of groundwater recharged in the area where the groundwater purification treatment device 14 is installed, from the viewpoint of groundwater level change of the well 16 and groundwater level management over a wider area, excessive groundwater from the well 16 It is necessary to prevent the occurrence of problems such as land subsidence due to pumping of water. For this reason, the operation | movement which carried out the severe restriction | limiting of the pumping amount of groundwater was made | formed.

And a data monitoring apparatus calculates the operation management data required for operation management for every some groundwater purification processing apparatus using the acquired groundwater level data. Specifically, when calculating operation management data of a specific groundwater purification treatment device among a plurality of groundwater purification treatment devices, the groundwater level of a well to be managed, which is a well related to the specific groundwater purification treatment device, and this Operation management data is calculated based on the groundwater level of the comparative observation well set in advance in the management target well. And the well set as a comparative observation well is set from the well which concerns on the groundwater purification processing apparatus different from the specific groundwater purification processing apparatus mentioned above at least one place. That is, based on the groundwater level of a well to be managed related to a specific groundwater purification treatment device and the groundwater level of a comparative observation well that is a well related to another groundwater purification treatment device, operation management of the specific groundwater purification treatment device is performed. The operation management data for performing is calculated.

  Furthermore, the well set as a comparative observation well with respect to the management object well which concerns on the specific groundwater purification processing apparatus among several groundwater purification processing apparatuses is the above-mentioned specific groundwater purification processing apparatus of at least one place. In addition to the wells related to the groundwater purification treatment apparatus, the wells are included in the wells related to the plurality of groundwater purification treatment apparatuses that have acquired the groundwater level by the data monitoring device. That is, the groundwater level data of each well acquired by the data monitoring device can be used not only as groundwater level data as a well to be managed but also as groundwater level data as a comparative observation well. . Thus, if each of the acquired groundwater level data is to be mutually used when calculating operation management data of a plurality of groundwater purification treatment devices, operation management data of a plurality of groundwater purification treatment devices over a wide area, It will be calculated efficiently.

(2) The operation management system of the groundwater purification treatment apparatus according to the above (1), wherein the comparative observation well is selected and set from a well that satisfies a predetermined comparison target condition according to the another groundwater purification treatment apparatus (Claim 2).
The operation management system of the groundwater purification treatment device described in this section is a well that is set as a comparative observation well for a management target well related to a specific groundwater purification treatment device among a plurality of groundwater purification treatment devices, It is selected and set from wells that satisfy a predetermined comparison target related to a groundwater purification treatment apparatus different from the specific groundwater purification treatment apparatus. The predetermined comparison target condition is set as an index for measuring the relevance with the management target well. Here, there are wells that are highly relevant to the managed wells, such as wells that share a common water vein, as the groundwater level changes in tandem with changes in the groundwater level of the managed wells. It is desirable that the conditions are set as comparative observation wells. By setting such wells that satisfy the comparison target as comparative observation wells for the management target wells, groundwater can be obtained in an appropriate amount considering the groundwater level in the area where the groundwater purification treatment equipment is installed. The operation management of the purification processing apparatus is performed.

(3) In the above item (2), the predetermined comparison target condition is that the distance from the management target well, the commonness of the water vein with the management target well, and the commonality of the groundwater basin with the management target well And an operation management system for a groundwater purification treatment apparatus including at least one condition (claim 3).
The operation management system of the groundwater purification treatment device described in this section is based on the distance from the well to be managed, where the predetermined comparison target condition when setting the comparative observation well is an index for measuring the relevance with the management well. It includes at least one of the commonality of the water vein with the management target well and the commonality of the groundwater basin with the management target well. Specifically, depending on the topography of the surrounding area where the groundwater purification treatment equipment related to the management target well is installed, the installation density of other surrounding groundwater purification treatment equipment, etc., the distance from the management target well, the management target well Appropriate conditions are set, including the commonality of water veins and groundwater basins.

  Specifically, for example, in the vicinity of the groundwater purification treatment device related to the management target well, when the number of other groundwater purification treatment devices installed is relatively large, the management target well and the water vein are common, In addition, a condition that is within a predetermined distance range (relatively narrow) from the management target well is set as a predetermined comparison target condition, and a well that is more relevant to the management target well may be selected. . In addition, in the vicinity of the groundwater purification treatment device related to the management target well, when the number of other groundwater purification treatment devices installed is small, it is within a predetermined distance range (relatively wide) from the management target well, and The wells that are related to the management target well may be selected by setting the conditions such as the fact that the management target well and the groundwater basin are common as a predetermined comparison target condition. Due to the comparison target conditions as described above, wells that are highly related to the management target well are set as comparative observation wells. Therefore, the operation management system for the groundwater purification treatment device described in this section is a management target well. More accurate operation management is performed in consideration of the groundwater level in the area where the groundwater purification treatment apparatus is installed.

(4) In the above items (1) to (3), the data monitoring device calculates a daily maximum water level that is a daily maximum water level from each of the groundwater level of the management target well and the groundwater level of the comparative observation well. An operation management system for a groundwater purification treatment apparatus that calculates and calculates the operation management data based on the highest water level of the day (Claim 4).
In the operation management system for the groundwater purification treatment device described in this section, the data monitoring device calculates the daily maximum water level, which is the maximum daily groundwater level, from the groundwater level data of the acquired wells to be managed, and further performs comparative observation. The daily maximum water level is also calculated from the groundwater level data of the well. This day's maximum water level usually decreases while being pumped by the groundwater purification treatment device, and recovers (rises) while pumping by the groundwater purification treatment device is stopped. Of these, it shows the groundwater level when it recovers to the maximum in one day. The highest water level on this day approximates the original static water level of groundwater. Here, when a plurality of comparative observation wells are set, the daily maximum water level may be calculated for each comparative observation well, and the average value of these daily maximum water levels may be used. Alternatively, the daily maximum water level may be calculated for each comparative observation well, and based on the relevance of each comparative observation well to the management target well, a combined value may be used while weighting these daily maximum water levels. Good.

  Then, based on the calculated daily maximum water level of the management target well and the daily maximum water level of the comparative observation well, operation management data of the groundwater purification treatment apparatus related to the management target well is calculated. Based on the operation management data calculated in this way, by controlling the operation of the groundwater purification treatment equipment related to the wells to be managed, the amount of groundwater purification treatment equipment with a more appropriate pumping amount considering the groundwater level in the surrounding area. Driving will be performed.

  (5) In the above item (4), the data monitoring device is configured such that, for each well of the management target well and the comparative observation well, the groundwater level of each well before the groundwater purification treatment device is operated. Alternatively, a reference maximum water level is set based on the daily maximum water level of each well in a predetermined period after the groundwater purification treatment apparatus is operated, and the amount of displacement between the daily maximum water level and the reference maximum water level is set. An operation management system for a groundwater purification treatment apparatus that calculates the operation management data based on the operation management data (claim 5).

  The operation management system for the groundwater purification treatment device described in this section is based on the groundwater level of the managed well before the operation of the groundwater purification treatment device related to the managed well. Based on the daily maximum water level of the management target well for a predetermined period after the processing apparatus is operated, the reference maximum water level of the management target well is set, and the reference maximum water level is also set for the comparative observation well. Specifically, the groundwater level of each well that has not yet been pumped before the operation of the groundwater purification treatment apparatus may be set as the reference maximum water level, or after the groundwater purification treatment apparatus is in operation It is also possible to calculate the daily maximum water level for a predetermined period of time and calculate the average value of these daily maximum water levels and set it as the reference maximum water level.

Then, the displacement amount between the daily maximum water level and the reference maximum water level is calculated for each well of the management target well and the comparative observation well. Here, when a plurality of comparative observation wells are set, the above-described displacement amount may be calculated for each comparative observation well, and an average value of these displacement amounts may be used. Or it is good also as calculating the displacement amount in each comparative observation well, and using the compounded value, weighting these displacement amounts based on the relation with the management object well of each comparative observation well.
Furthermore, based on the calculated displacement amount of the management target well and the displacement amount of the comparative observation well, operation management data of the groundwater purification treatment apparatus related to the management target well is calculated. Therefore, the recovery status of the groundwater level based on the reference maximum water level for each well to be managed and the comparative observation well will be grasped and the operation management of the groundwater purification treatment equipment will be performed. The groundwater purification treatment device is operated with the pumped amount of water.

  (6) In the above item (5), the data monitoring device further calculates a daily minimum water level, which is a daily minimum water level, from each of the groundwater level of the well to be managed and the groundwater level of the comparative observation well, For each well of the management target well and the comparative observation well, the water level of each well before the groundwater purification treatment apparatus is operated, or the predetermined period after the groundwater purification treatment apparatus is activated Based on the daily minimum water level of each well, set a reference minimum water level, and calculate the operation management data based on the amount of displacement between the daily minimum water level and the reference minimum water level. System (claim 6).

In the operation management system for the groundwater purification treatment device described in this section, the data monitoring device calculates the daily minimum water level, which is the minimum groundwater level for each day, from the groundwater level data of the wells to be managed. The daily minimum water level is also calculated from the groundwater level data of the well. The minimum water level on this day is a dynamic water level that usually falls while being pumped by the groundwater purification treatment device and recovers (rises) while the pumping by the groundwater purification treatment device is stopped. This shows the groundwater level at the time when the groundwater level drops most in a day. Here, when multiple comparative observation wells are set, the average daily minimum water level of each comparative observation well and the daily minimum water level of each comparative observation well are weighted in the same way as the daily maximum water level. We will use complex values.
In addition, the data monitoring device is a management target well for a predetermined period after the groundwater level of the management target well before the operation of the groundwater purification processing device related to the management target well or the operation of the groundwater purification processing device related to the management target well is started. Based on the daily minimum water level, set the reference minimum water level for the wells to be managed, and also set the reference minimum water level for the comparative observation wells. Specifically, subtract the water level calculated from the amount of pumped water when the groundwater purification treatment device is in operation from the groundwater level of each well that has not yet been pumped before the operation of the groundwater purification treatment device, You may set as a standard minimum water level. Alternatively, the daily minimum water level for a predetermined period after the operation of the groundwater purification apparatus may be calculated, and the average value of these daily minimum water levels may be calculated and set as the reference minimum water level.

Further, the data monitoring device calculates the amount of displacement between the daily minimum water level and the reference minimum water level for each well of the management target well and the comparative observation well. Here, when a plurality of comparative observation wells are set, as with the daily minimum water level, an average value, a value combined with weighting, or the like is used for this displacement amount.
Then, based on the calculated displacement amount of the management target well and the displacement amount of the comparative observation well, operation management data of the groundwater purification treatment apparatus related to the management target well is calculated. Based on the operation management data calculated in this way, for example, by performing operation management of the groundwater purification treatment apparatus related to the management target well, for example, the daily minimum water level in the negative direction based on the reference minimum water level of the management target well If the amount of displacement is clearly larger than the daily minimum water level in the negative direction relative to the reference minimum water level of the comparative observation well, recovery of the groundwater level of the managed well (rise) It is determined that the speed is slow. For this reason, the occurrence of an abnormality in the management target well will be detected at an early stage.

(12) In the above item (11), from each of the groundwater level of the management target well and the groundwater level of the comparative observation well, a daily minimum water level that is a daily minimum water level is calculated, and the management target well and the For each well with a comparative observation well, the water level of each well before the groundwater purification treatment apparatus is operated, or the day of each well during a predetermined period after the groundwater purification treatment apparatus is activated An operation management method for a groundwater purification treatment apparatus that sets a reference minimum water level based on a minimum water level and performs operation management based on a displacement amount between the daily minimum water level and the reference minimum water level (claim 12).

Only the location is set. In addition, the code | symbol SL of FIG.2 (b) has shown the static water level of the management object well 16T and the comparative observation well 16Xa.

Subsequently, referring to the flow charts shown in FIGS. 3 to 5, the present invention in the case where one comparative observation well 16 </ b> Xa is set for the management target well 16 </ b> T as shown in FIG. 2. The procedure of the operation management method by the operation management system 10 of the groundwater purification treatment apparatus according to the embodiment will be described. In addition, please refer FIG. 1 about the structure of the operation management system 10 of a groundwater purification processing apparatus, and FIG. 2 about the relationship between the management object well 16T and the comparative observation well 16Xa suitably.
First, the main procedure performed every day of the operation management method by the operation management system 10 of the groundwater purification treatment apparatus will be described with reference to the main flow shown in FIG.
S10: The groundwater levels of the management target well 16T and the comparative observation well 16Xa are measured. The measurement of the groundwater level is continuously performed by water level measuring instruments 18T and 18Xa installed in each of the management target well 16T and the comparative observation well 16Xa. The measured groundwater level data is acquired and stored by the data calculation device 24 constituting the data monitoring device 30 via the communication means 20. As an example, FIG. 6 shows a graph of groundwater level data relating to a specific well acquired during the period from July 1st to 4th. Note that a graph as shown in FIG. 6 may be displayed to the monitor by the monitor device 28 constituting the data monitoring device 30.

  S20: The data arithmetic unit 24 calculates the daily maximum water level and the daily minimum water level of each of the management target well 16T and the comparative observation well 16Xa based on the acquired groundwater level data. The daily maximum water level is the highest water level in a day of the groundwater level measured continuously. In the example of FIG. 6, the water level at the time indicated by the black arrow described for each day is the daily maximum water level. It corresponds to. On the other hand, the lowest daily water level is the lowest water level of the groundwater level continuously measured in one day. In the example of FIG. 6, the water level at the time indicated by the white arrow described for each day is Corresponds to the lowest water level. Since the daily maximum water level and daily minimum water level require calculation of groundwater level data for one day, the daily maximum water level and daily minimum water level are calculated based on the groundwater level data measured on the previous day, for example. Done. The calculated daily maximum water level and daily minimum water level of each of the management target wells 16T and the comparative observation wells 16Xa are stored by the data calculation device 24.

Details of the determination of the change in the still water level will be described later.
S40: The daily minimum water level calculated in S20 above is treated as the dynamic water level of each of the management target well 16T and the comparative observation well 16Xa, and the change of the dynamic water level using the daily minimum water level is determined (transition to S300 in FIG. 5). . Details of the determination of changes in the dynamic water level will be described later.
The procedure shown in S30 and S40 is performed in S20 using, for example, the daily maximum water level and the daily minimum water level calculated based on the groundwater level data measured on the previous day. The effect of pumping water appears to be a gradual effect on the groundwater in the surrounding area, so it is particularly problematic to manage the operation of the groundwater purification treatment equipment using the groundwater level data measured the day before. There is no.

Next, according to the static water level change determination flow shown in FIG. 4, when the single comparative observation well 16 </ b> Xa is set for the management target well 16 </ b> T in the operation management method by the operation management system 10 of the groundwater purification treatment apparatus. The operation management procedure using the daily maximum water level will be described.
S100: The process proceeds from S30 of the main flow (see FIG. 3) described above, and this procedure is started.
S110: The monitoring device 28 constituting the data monitoring device 30 acquires the daily maximum water levels of the management target well 16T and the comparative observation well 16Xa calculated by the data calculation device 24 via the communication unit 32. At this time, the daily maximum water level for the predetermined date is acquired.

Thereby, the supervisor grasps | ascertains the change of the daily maximum water level of the predetermined period day about each of the management object well 16T and the comparative observation well 16Xa.

  S130: For each of the management target well 16T and the comparative observation well 16Xa, the data computing device 24 calculates and stores the amount of displacement of the daily maximum water level from the reference maximum water level. The reference maximum water level is set in advance for each of the wells 16T and 16Xa to 16Xf related to the plurality of groundwater purification treatment devices 14T and 14Xa to 14Xf managed by the operation management system 10 of the groundwater purification treatment device. The reference maximum water level includes, for example, the groundwater level of each well before the operation of the groundwater purification treatment apparatus for each well and the daily maximum water level for a predetermined period after the operation of the groundwater purification treatment apparatus for each well. Is set for each well.

  S140: The amount of displacement of the daily maximum water level from the reference maximum water level for each of the management target well 16T and the comparative observation well 16Xa calculated by the data calculation device 24 via the communication unit 32 is acquired by the monitoring device 28.

And the graph which shows the displacement amount over the predetermined date of the management object well 16T and the comparative observation well 16Xa which is illustrated to FIG. 7 (b) with respect to a supervisor is displayed. In the graph of FIG. 7B, the line with the displacement amount of 0 indicates the reference maximum water level of the management target well 16T and the comparative observation well 16Xa, and the displacement amount is in the plus direction (upward in the figure) than 0. Indicates that the daily maximum water level is higher than the reference maximum water level, and if the displacement is in the negative direction (downward in the figure), it indicates that the daily maximum water level is lower than the reference maximum water level.

It is determined whether or not. Referring to the graph of FIG. 7B as an example, the most recent displacement amount, that is, the displacement amount shown at the right end of the graph is lower than the first displacement reference value from the displacement amount 0 line in the downward direction in the figure. Whether it is in the (minus direction) is determined for both the management target well 16T and the comparative observation well 16Xa. When it is determined that the displacement amounts of both the management target well 16T and the comparative observation well 16Xa are in the negative direction beyond the first displacement reference value (YES), the process proceeds to S160, and the management target well 16T and If it is determined that the amount of displacement with respect to the comparative observation well 16Xa or any one of the displacement amounts is not in the negative direction beyond the first displacement reference value (NO), the process proceeds to S170. The first displacement reference value is set in advance, and is set to a relatively large value (for example, about 20 m) with respect to the second displacement reference value described later, and changes in the groundwater level of each well. In consideration of characteristics, a different value may be set for each well, or a value common to each well may be set.

When it is determined that the displacement amounts of both the management target well 16T and the comparative observation well 16Xa are in the negative direction beyond the second displacement reference value (YES), the process proceeds to S180, and the management target well 16T and If it is determined that the amount of displacement with respect to both of the comparative observation wells 16Xa or one of the displacement amounts is not in the minus direction beyond the second displacement reference value (NO), the process proceeds to S190. The second displacement reference value is set in advance, is set to a relatively small value (for example, about 10 m), and is a value that differs for each well in consideration of the change characteristics of the groundwater level of each well. Or a common value for each well may be set.

  S180: When it is determined in S170 that the displacement amounts of both the management target well 16T and the comparative observation well 16Xa are in the negative direction beyond the second displacement reference value (YES), the management target well 16T and the comparison well It is determined that the amount of groundwater pumped in the surrounding area including the observation well 16Xa is becoming excessive, and the amount of groundwater pumped by the groundwater purification treatment device 14T from the management target well 16T is limited to 50%.

It may be set as a comparative observation well of the well 16T.

  Next, with reference to FIG. 14, an example of a setting pattern different from that in FIG. 13 when a comparative observation well is set for the management target well 16T will be described. In the example of FIG. 14A, wells 16Xa to 16Xd related to a plurality of groundwater purification treatment apparatuses that are managed by the operation management system 10 of the groundwater purification treatment apparatus within a distance range SC centered on the management target well 16T. Is installed. However, the mountain range 42 is included in the distance range SC centered on the management target well 16T, and the management target well 16T and the wells 16Xc and Xd are separated by the mountain range 42.

  In such a case, it is assumed that the predetermined comparison target condition when setting the comparative observation well is a well having a groundwater basin within the distance range SC from the management target well 16T and in common with the management target well 16T. Then, the wells 16Xa and 16Xb, which are located on the lower right side of the mountain range 42 as in the management target well 16T, have a groundwater basin common to the management target well 16T, and thus are set as comparative observation wells. . On the other hand, unlike the management target well 16T, the wells 16Xc and 16Xd located on the upper left side in the figure with respect to the mountain range 42 do not have a common groundwater basin with the management target well 16T. Even if it is installed in the SC, it is not set as a comparative observation well. In addition, when there is a groundwater basin common to the management target well 16T like the wells 16Xa and 16Xb, as shown in FIG. 14 (b), water is taken from the water vein common to the management target well 16T. It is expected that there is a high possibility.

  Now, according to the embodiment of the present invention configured as described above, the following operational effects can be obtained. That is, the operation management system 10 of the groundwater purification treatment apparatus according to the embodiment of the present invention is installed for each well 16 (16T and 16Xa to 16Xf), as shown in FIG. A plurality of groundwater purification treatment devices 14 (14T and 14Xa to 14Xf) for performing purification treatment, and water level measuring instruments 18 (18T and 18Xa to 18Xf) associated with each of the plurality of groundwater purification treatment devices 14, The water level measuring device 18 measures the ground water level of each well 16 that changes depending on the operation status of the ground water purification treatment device 14. The water level measuring instrument 18 is a measuring instrument capable of continuous measurement, such as a pressure sensor used by being set in the well 16 as shown in FIG. 1 or an ultrasonic sensor that measures the distance to the ground water surface. Is used. Further, the operation management system 10 of the groundwater purification treatment apparatus includes a data monitoring device 30 including a data calculation device 24 and a monitor device 28, and communication means 20 (20T and 20Xa to 20Xf, 20Z). Data communication is performed between each of the plurality of groundwater purification treatment apparatuses 14 and the data monitoring apparatus 30 via the means 20. As the communication means 20, a wireless system as shown in FIG. 1 or a wired system is appropriately used according to the distance between each groundwater purification treatment device 14 and the data monitoring device 30. The data monitoring device 30 uses various computers including a storage device and an arithmetic device.

  The data monitoring device 30 acquires the groundwater level data of each well 16 measured by the water level measuring device 18 from each of the plurality of groundwater purification treatment devices 14, and the groundwater for each well 16 related to the plurality of groundwater purification treatment devices 14. The position data is managed (see FIG. 6). And the data monitoring apparatus 30 calculates the operation management data required for operation management for every some groundwater purification processing apparatus 14 using the acquired groundwater level data. Specifically, when calculating operation management data of a specific groundwater purification treatment device 14T among a plurality of groundwater purification treatment devices 14, the groundwater of the management target well 16T that is a well associated with the specific groundwater purification treatment device 14T. The operation management data is calculated on the basis of the position and the groundwater level of the comparative observation well preset in the management target well 16T. And the well set as a comparative observation well is set from the wells 16Xa-16Xf concerning the groundwater purification treatment apparatus 14Xa-14Xf different from the specific groundwater purification treatment apparatus 14T mentioned above at least one place.

  That is, the groundwater of the comparative observation well that is set at least one of the groundwater level of the management target well 16T related to the specific groundwater purification treatment device 14T and the wells 16Xa to 16Xf related to the other groundwater purification treatment devices 14Xa to 14Xf Based on the position, operation management data for performing operation management of the specific groundwater purification treatment device 14T is calculated. Each of the plurality of groundwater purification treatment devices 14 is managed by performing operation management of each of the plurality of groundwater purification treatment devices 14 based on such operation management data calculated for each of the plurality of groundwater purification treatment devices 14. The appropriate amount of pumped water that can take into account the groundwater level between the well 16 according to the above and another well 16 that is set in advance, and suppress the occurrence of problems such as ground subsidence caused by excessive pumping of groundwater Thus, it becomes possible to operate the groundwater purification treatment apparatus 14.

  Furthermore, the well set as a comparative observation well with respect to the management target well 16T related to the specific groundwater purification treatment apparatus 14T among the plurality of groundwater purification treatment apparatuses 14 is at least one specific groundwater described above. Separately from the purification treatment device 14T, the well 16 is related to the groundwater purification treatment device 14, and at the same time, the wells 16Xa to 16Ga to the plurality of groundwater purification treatment devices 14Xa to 14Xf that acquire the groundwater level by the data monitoring device 30. It is included in 16Xf. That is, the groundwater level data of each well 16 acquired by the data monitoring device 30 can be used not only as groundwater level data as the management target well 16T but also as groundwater level data as a comparative observation well. Is. As described above, when each of the acquired groundwater level data is to be mutually used when calculating the operation management data of the plurality of groundwater purification treatment apparatuses 14, the operation management data of the plurality of groundwater purification treatment apparatuses 14 over a wide area. Can be calculated efficiently.

  Moreover, the operation management system 10 of the groundwater purification treatment apparatus according to the embodiment of the present invention performs comparative observation on the management target well 16T related to the specific groundwater purification treatment apparatus 14T among the plurality of groundwater purification treatment apparatuses 14. The well 16 set as a well is selected and set from wells satisfying a predetermined comparison target related to a groundwater purification treatment device different from the specific groundwater purification treatment device 14T. The predetermined comparison target condition is set as an index for measuring the relevance with the management target well 16T, and the management is such that the groundwater level changes slowly in conjunction with the change in the groundwater level of the management target well 16T. A well that is highly related to the target well 16T, for example, a well 16Xa having a common water vein as shown in FIG. 2 is set as a comparative observation well. By setting such a well 16Xa that satisfies the comparison target as a comparative observation well of the management target well 16T, an appropriate pumping amount in consideration of the groundwater level of the area where the groundwater purification treatment device 14 is installed is obtained. In addition, it becomes possible to perform operation management of the groundwater purification treatment apparatus 14.

  Furthermore, in the operation management system 10 of the groundwater purification treatment apparatus according to the embodiment of the present invention, the predetermined comparison target condition when setting the comparative observation well is an index for measuring the relevance with the management target well 16T. It includes at least one condition among the distance from the management target well 16T, the commonality of the water vein with the management target well 16T, and the commonality of the groundwater basin with the management target well 16T. Specifically, according to the topography of the surrounding area where the groundwater purification treatment apparatus 14T related to the management target well 16T is installed, the installation density of other surrounding groundwater purification treatment apparatuses 14, the distance from the management target well 16T, Appropriate conditions are set so as to include the commonity of the water vein and groundwater basin with the well 16T to be managed.

  More specifically, for example, in the case where the number of other groundwater purification treatment apparatuses installed in the vicinity of the groundwater purification treatment apparatus 14T related to the management target well 16T is relatively large, as shown in FIG. 16T and water veins are common, and within a predetermined distance range SC (relatively narrow) from the management target well 16T, and other conditions are set as predetermined comparison target conditions, and more related to the management target well 16T. A well having high properties (16Xa and 16Xe, 16Xb and 16Xd, 16Xc and 16Xf, or 16Xa to 16Xf) may be selected. Further, when the number of other groundwater purification treatment apparatuses 14T installed around the groundwater purification treatment apparatus 14T related to the management target well 16 is small, as shown in FIG. The wells 16Xa and 16Xb that are related to the management target well 16T are defined as conditions for comparison, such as being within the distance range SC, and having the management target well 16T and the groundwater basin in common. What is necessary is just to make it select. Due to the comparison target conditions as described above, a well highly related to the management target well 16T is set as a comparative observation well. Therefore, the operation management system 10 of the groundwater purification treatment apparatus relates to the management target well 16T. More accurate operation management in consideration of the groundwater level in the area where the groundwater purification treatment apparatus 14T is installed can be performed.

  Moreover, as shown in FIG. 2, the operation management system 10 of the groundwater purification processing apparatus according to the embodiment of the present invention is based on the groundwater level data of the management target well 16T acquired by the data monitoring apparatus 30 (see FIG. 1). The daily maximum water level, which is the maximum daily groundwater level, is calculated, and the daily maximum water level is also calculated from the groundwater level data of the comparative observation well 16Xa (see S20 in FIG. 3, FIG. 7A). The highest water level of this day usually decreases while being pumped by the groundwater purification treatment device 14 and recovers (rises) while the pumping by the groundwater purification treatment device 14 is stopped. This shows the groundwater level at the time of maximum recovery in the day. The highest water level on this day approximates the original static water level of groundwater. Here, as shown in FIG. 9, when a plurality of comparative observation wells 16Xa to 16Xf are set, the daily maximum water level is calculated in each comparative observation well and the average value of these daily maximum water levels is used. (S60 in FIG. 10). Alternatively, the daily maximum water level is calculated for each comparative observation well, and based on the relevance of each comparative observation well to the management target well 16T, the combined value while weighting the daily maximum water level is used. Also good.

  Then, based on the calculated daily maximum water level of the management target well 16T and the daily maximum water level of the comparative observation well 16Xa, the operation management data of the groundwater purification treatment apparatus 14T related to the management target well 16T is calculated (see FIG. 4). . Based on the operation management data calculated in this way, by performing operation management of the groundwater purification treatment device 14T related to the management target well 16T, the groundwater purification treatment with a more appropriate pumping amount in consideration of the groundwater level in the surrounding area. The apparatus 14T can be operated.

  Furthermore, in the operation management system 10 for the groundwater purification treatment apparatus according to the embodiment of the present invention, the groundwater level of the management target well 16T before the data monitoring device 30 operates the groundwater purification treatment apparatus 14T related to the management target well 16T. Alternatively, based on the daily maximum water level of the management target well 16T for a predetermined period after the operation of the groundwater purification treatment device 14T related to the management target well 16T, the reference maximum water level of the management target well 16T is set, and further comparative observation is performed. Similarly, the reference maximum water level is set for the well 16Xa. Specifically, the groundwater level of each well 16 that has not yet been pumped before the operation of the groundwater purification treatment device 14 may be set as the reference maximum water level, or the groundwater purification treatment device 14 may be The daily maximum water level for a predetermined period after operation may be calculated, and the average value of these daily maximum water levels may be calculated and set as the reference maximum water level.

Then, for each well of the management target well 16T and the comparative observation well 16Xa, the amount of displacement between the daily maximum water level and the reference maximum water level is calculated (see S130 in FIG. 4 and FIG. 7B). Here, when a plurality of comparative observation wells 16Xa to 16Xf are set as shown in FIG. 9, the above-described displacement amount is calculated in each comparative observation well, and the average value of these displacement amounts is used. (S530 in FIG. 11). Or it is good also as calculating the displacement amount in each comparative observation well, and using the compounded value, weighting these displacement amounts based on the relationship with the management target well 16T of each comparative observation well. .
Further, based on the calculated displacement amount of the management target well 16T and the displacement amount of the comparative observation well 16Xa, the operation management data of the groundwater purification treatment apparatus 14T related to the management target well 16T is calculated. Therefore, since the recovery state of the groundwater level with respect to each well of the management target well 16T and the comparative observation well 16Xa is grasped and the operation management of the groundwater purification treatment device 14T is performed, Furthermore, it becomes possible to operate the groundwater purification treatment apparatus 14T with an appropriate pumping amount.

  Moreover, the operation management system 10 of the groundwater purification processing apparatus according to the embodiment of the present invention is configured such that the data monitoring apparatus 30 obtains the lowest daily water level that is the minimum groundwater level for each day from the acquired groundwater level data of the management target well 16T. Further, the daily minimum water level is calculated from the groundwater level data of the comparative observation well 16Xa (see S20 in FIG. 3, FIG. 8A). The minimum water level on this day is a dynamic water level that usually decreases while being pumped by the groundwater purification treatment device 14 and recovers (rises) while pumping by the groundwater purification treatment device 14 is stopped. Of the sixteen hourly groundwater levels, this shows the groundwater level when it drops most in a day. Here, when a plurality of comparative observation wells 16Xa to 16Xf are set as shown in FIG. 9, the average daily minimum water level of each comparative observation well (S60 in FIG. ), Or the combined value while weighting the daily minimum water level of each comparative observation well.

  In addition, the data monitoring device 30 has the groundwater level of the management target well 16T before the operation of the groundwater purification treatment device 14T related to the management target well 16T, or after the operation of the groundwater purification treatment device 14T related to the management target well 16T. Based on the daily minimum water level of the management target well 16T for a predetermined period, the reference minimum water level of the management target well 16T is set, and the reference minimum water level is also set for the comparative observation well 16Xa. Specifically, from the groundwater level of each well 16 that has not yet been pumped before the groundwater purification treatment device 14 is operated, the water level calculated from the pumped amount assumed when the groundwater purification treatment device 14 is operated is You may subtract and set it as a standard minimum water level. Alternatively, the daily minimum water level for a predetermined period after the operation of the groundwater purification apparatus 14 may be calculated, and the average value of these daily minimum water levels may be calculated and set as the reference minimum water level.

Further, the data monitoring device 30 calculates the displacement between the daily minimum water level and the reference minimum water level for each of the management target well 16T and the comparative observation well 16Xa (see S330 in FIG. 5 and FIG. 8B). ). Here, as shown in FIG. 9, in the case where a plurality of comparative observation wells 16Xa to 16Xf are set, as with the daily minimum water level, this displacement is also compounded while averaging and weighting. Values etc. will be used.
Then, based on the calculated displacement amount of the management target well 16T and the displacement amount of the comparative observation well 16Xa, the operation management data of the groundwater purification treatment apparatus 14T related to the management target well 16T is calculated. Based on the operation management data calculated in this way, by performing operation management of the groundwater purification treatment device 14T related to the management target well 16T, for example, the daily minimum water level minus the reference minimum water level of the management target well 16T. When the amount of displacement in the direction is clearly larger than the amount of displacement in the minus direction of the daily minimum water level relative to the reference minimum water level of the comparative observation well 16Xa (S350 in FIG. 5), the management It can be determined that the groundwater level recovery (rise) speed of the target well 16T is slow. Thus, it becomes possible to detect the occurrence of abnormality in the management target well 16T at an early stage.
