Description
Technical Field
The present invention relates to a water collector (water agglomerator), a water circulation system, a control apparatus, a control method, and a computer-readable recording medium having a control program recorded thereon.
Background
Some regions are frequently damaged by rainstorms due to recent climate change, and on the other hand, some regions are continuously drought for years, so that water resources are expensive year by year. In particular, industrial water is expected to be more expensive and higher in price because of its lower priority than agricultural water. Therefore, in terms of industrial use, it is considered that reuse of water at a certain cost is more often performed than in the case of purchasing purified water.
Patent document 1 discloses a circulating water utilization system including: a purification device that purifies circulating water containing discharge water flowing through the circulation flow path in stages by passing the circulating water through two or more water quality levels; and a supply device for supplying the circulating water of a water quality grade selected from the circulating water of more than two water quality grades by each small amount water demand body to each small amount water demand body.

Disclosure of Invention
Problems to be solved by the invention
In the circulating water utilization system disclosed in patent document 1, a purification device for purifying circulating water in stages by passing the circulating water through two or more water quality levels is required.
However, the water quality required in facilities using water such as factories varies depending on the application. High water quality is sometimes required, such as ultrapure water used for semiconductor production or pharmaceutical production, and high water quality is not sometimes required, such as water for cooling. In the case where water discharged from some facilities or processes can be directly used for other facilities or processes, introduction into the purification apparatus causes a loss.
In addition, water quality cannot be simply graded. In some facilities or processes, the concentration of a volatile organic compound may be an index of water quality, but in other facilities or processes, the concentration of a metal compound may be an index of water quality or the pH may be an index of water quality. Thus, unless the water is purified according to the required water quality index, the introduction of the purification apparatus also causes a loss.
The purpose of the present invention is to promote the effective use of water.
Means for solving the problems
A water collector according to an aspect of the present invention includes:
one or more 1 st water storage tanks for storing water discharged from one or more of the two or more facilities using water;
one or more 2 nd water storage tanks for storing water supplied to at least one of the two or more facilities;
water supply means for supplying water from the one or more 1 st water storage tanks to the one or more 2 nd water storage tanks;
a checking device for checking the water quality of the more than one 1 st water storage tank; and
and a controller that determines whether or not the water stored in the one or more 1 st water storage tanks meets a water quality criterion set in the one or more 2 nd water storage tanks based on a result of the detection by the detection device, and instructs the water supply mechanism to supply water from the 1 st water storage tank in which the water meeting the one water quality criterion is stored to the 2 nd water storage tank in which the one water quality criterion is set.
Effects of the invention
In the present invention, it is determined whether or not water discharged from a certain facility can be supplied to the same facility or another facility based on the result of the water quality inspection. Therefore, introduction of an unnecessary purification apparatus and an unnecessary purification process can be avoided, and effective use of water can be promoted.

Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. In the description of the embodiments, the same or corresponding portions will be omitted or simplified as appropriate.
Embodiment 1.
The present embodiment will be described with reference to fig. 1 to 6.
Description of the constituent
The structure of the water circulation system 100 according to the present embodiment will be described with reference to fig. 1.
The water circulation system 100 may be installed in any place or area, and in the present embodiment, is installed in an industrial area. The water circulation system 100 may be constructed across two or more industrial areas.
The water circulation system 100 has a sump 110 and two or more facilities 120 using water.
Specifically, each facility 120 is a factory in an industrial area. The number of facilities 120 may be any number, and in the present embodiment is 8. It should be noted that the facility 120 does not have to be a factory in the same industrial area.
The water utilized in each facility 120 is supplied or drained to the same facility 120 or other facilities 120 through the sump 110.
The water collector 110 is connected to each facility 120 through a 1 st pipe 131, a 2 nd pipe 132, and a 3 rd pipe 133. The 1 st pipe 131 is a pipe for transporting reusable water from each facility 120 to the water collector 110. The 2 nd pipe 132 is a pipe for water quality coordinated with the sump 110, that is, a pipe for transporting reusable water from the sump 110 to each facility 120. The 3 rd pipe 133 is a pipe for transporting the sewage that cannot be reused from each facility 120 to the water collector 110. The drainage treatment of the water transferred through the 3 rd pipe 133 is performed in the sump 110. The type and number of pipes may be changed as appropriate.
Each facility 120 is connected to a common water supply pipe, not shown, via a 4 th pipe 134. The 4 th pipe 134 is a pipe for transporting the supply water from the outside to each facility 120. Each facility 120 is not limited to being connected to a common water supply line, and may be connected to a water supply source having the same or higher water quality than the water supply line.
The configuration of the water collector 110 and each facility 120 according to the present embodiment will be described with reference to fig. 2.
Since the structures of the facilities 120 are common, only one structure of one facility 120 is shown in fig. 2.
As described above, the water quality required in a plant varies depending on the application. High water quality is sometimes required, such as ultrapure water used for semiconductor production or pharmaceutical production, and high water quality is not sometimes required, such as water for cooling.
Further, the index of water quality varies depending on factories or processes. The concentration of volatile organic compounds may be an index of water quality, the concentration of metal compounds may be an index of water quality, and the pH may be an index of water quality.
Therefore, it is not rare that the industrial water used in a certain process of a certain plant is of a sufficient quality to be used in a certain process of another plant. Industrial water used in a certain process of a certain plant is purified at a low cost, and it is not rare that the water quality is sufficient for use in a certain process of another plant.
The sump 110 defines a water quality reference of the drawn water, and prompts a purchase price and a sale price of the water to the facility 120 as a user. In the present embodiment, one water quality standard is defined, but two or more water quality standards may be defined.
Industrial water satisfying a defined water quality standard is transferred between facility 120 as a plant and water collector 110.
The facility 120 includes a washing apparatus 121, a purification apparatus 122, a facility 123, a 4 th water storage tank 124, a 5 th water storage tank 125, a discharge mechanism 126, and a control apparatus 127.

The facility 123 is a device, equipment, or a combination thereof that performs a step different from the cleaning step with water supplied from the sump 110 via the 2 nd pipe 132.
The 4 th water storage tank 124 is a water storage tank for storing water of a certain water quality. The number of the 4 th water storage tanks 124 is one in the present embodiment, but may be two or more. In particular, when two or more water quality standards are defined in the water collector 110, two or more 4 th water storage tanks 124 corresponding to different water quality standards may be provided in the facility 120.
The 5 th water storage tank 125 is a water storage tank for storing water having a water quality lower than that of the water stored in the 4 th water storage tank 124. The number of the 5 th water storage tanks 125 is one in the present embodiment, but may be two or more.
In the present embodiment, the cleaning device 121 consumes a large amount of water, but the water quality is not so poor. Therefore, as the purification device 122, a low-cost device can be used. In the case where the water quality standard defined in the sump 110 can be satisfied even after the washing process, the purification device 122 may be omitted and the water used in the washing device 121 may be directly supplied to the 4 th water storage tank 124. In the water circulation system 100, a facility 120 provided with the purification apparatus 122 and a facility 120 not provided with the purification apparatus 122 may be mixed. That is, the configuration of each facility 120 may not be common.
The discharge mechanism 126 is a device, machine, or combination thereof that discharges the water. Specifically, the discharge mechanism 126 is a valve, a pump, or a combination thereof.
The control device 127 is a computer that controls the cleaning device 121, the purification device 122, the facility 123, and the discharge mechanism 126.
The water collector 110 includes a 1 st water storage tank 111, a 2 nd water storage tank 112, a 3 rd water storage tank 113, a water feeding mechanism 114, a detection device 115, a discharge mechanism 116, and a control device 117.
The 1 st water storage tank 111 is a water storage tank for storing water discharged from one or more facilities 120. The 1 st water storage tank 111 may correspond to the facilities 120 in a one-to-one manner, or may correspond to the facilities 120 in a one-to-many manner. In any case, the 1 st water storage tank 111 stores water discharged from the corresponding facility 120. The number of the 1 st water storage tanks 111 is one in the present embodiment, but is desirably two or more. It is desirable that at least one of the 1 st water storage tanks 111 is provided for each facility 120.
The 2 nd water storage tank 112 is a water storage tank for storing water supplied to the at least one facility 120. A water quality reference is set for the 2 nd water storage tank 112. The water quality standard corresponds to a water quality standard defined in the water collector 110. The number of the 2 nd water storage tanks 112 is one in the present embodiment, but may be two or more. In particular, when two or more water quality standards are defined, the water collector 110 includes two or more 2 nd water storage tanks 112 having different water quality standards.
The 3 rd water storage tank 113 is a water storage tank for storing water that does not meet the water quality standard set in the 2 nd water storage tank 112. The number of the 3 rd water storage tanks 113 is one in the present embodiment, but may be two or more.
The water supply mechanism 114 is a device, an apparatus, or a combination thereof for supplying water from the 1 st water storage tank 111 to the 2 nd water storage tank 112 or the 3 rd water storage tank 113. Specifically, the water supply mechanism 114 is a valve, a pump, or a combination thereof.
The inspection device 115 inspects the water quality in the 1 st water storage tank 111.
The discharge mechanism 116 is a device, machine, or combination thereof that discharges the water. Specifically, the discharge mechanism 116 is a valve, a pump, or a combination thereof.
The water stored in the 4 th water storage tank 124 of the facility 120 is transferred to the water collector 110 through the 1 st pipe 131 by the discharge mechanism 126 of the facility 120, and stored in the 1 st water storage tank 111.
The water quality of the water stored in the 1 st water storage tank 111 is checked by the checking device 115. When the water quality criterion is satisfied, the water stored in the 1 st water storage tank 111 is transferred to the 2 nd water storage tank 112 by the water transfer mechanism 114. On the other hand, if the defined water quality standard is not satisfied, the water stored in the 1 st water storage tank 111 is transferred to the 3 rd water storage tank 113 as contaminated water by the water transfer mechanism 114. The water stored in the 2 nd water storage tank 112 is delivered to the facility 120 through the 2 nd pipe 132 by the discharge mechanism 116, and is used in the facility 123 of the facility 120. This water is not as high in quality as that used in the washing step, and therefore can be purchased at a low price. On the other hand, the water stored in the 3 rd water storage tank 113 is discarded.
The water stored in the 5 th water storage tank 125 of the facility 120 is transferred to the sump 110 through the 3 rd pipe 133 by the discharge mechanism 126 of the facility 120, and stored in the 3 rd water storage tank 113. As described above, the water stored in the 3 rd water storage tank 113 is discarded.

Description of actions
The operations of the control device 117 of the water collector 110 and the control device 127 of each facility 120 according to the present embodiment will be described with reference to fig. 4 to 6.
Fig. 4 shows the operation of the control device 127 when the cleaning process is performed by the cleaning device 121 in a certain facility 120.
In step S11, the control device 127 receives information indicating that the cleaning process has been performed from the cleaning device 121. The control device 127 instructs the purification device 122 to detoxify the water used in the washing device 121 based on the received information.
In step S12, the control device 127 instructs the purification device 122 to supply water that has reached the water quality standard indicated by the water collector 110 to the 4 th water storage tank 124 and supply the remaining contaminated water to the 5 th water storage tank 125 in advance. In the case where two or more water quality standards are defined and two or more 4 th water storage tanks 124 corresponding to different water quality standards are provided in the facility 120, the controller 127 instructs the purifier 122 to distribute water reaching each water quality standard to the corresponding 4 th water storage tank 124.
In step S13, the control device 127 instructs the discharge mechanism 126 to deliver the water stored in the 4 th water storage tank 124 to the water collector 110.
Fig. 5 shows the action of the control device 117 when water is purchased by a certain facility 120 in the sump 110. The operation of the control device 117 corresponds to the control method of the present embodiment. The operation of the control device 117 corresponds to the processing procedure of the control program of the present embodiment.
In step S21, the control unit 230 of the control device 117 performs a transaction process for purchasing water at a preset price.
In step S22, the control unit 230 of the control device 117 instructs the examination device 115 to examine the water quality in the 1 st water storage tank 111.
In step S23, communication unit 210 of control device 117 receives the result of the detection by detection device 115 using communication device 205.
In step S24, the determination unit 220 of the control device 117 determines whether or not the water stored in the 1 st water storage tank 111 matches the water quality criterion set in the 2 nd water storage tank 112, based on the result of the check received by the communication unit 210. The water quality standard is stored in the memory 202 as a water quality profile in which a threshold range is specified for at least one of various indexes such as the concentration of volatile organic compounds, the concentration of metal compounds, and the pH. Thus, the determination unit 220 accesses the memory 202 and compares the result of the inspection by the inspection device 115 with the water quality profile to determine whether or not the water stored in the 1 st water storage tank 111 matches the water quality criterion. If yes, the process of step S25 is performed, and if no, the process of step S26 is performed. When two or more water quality standards are defined, each water quality profile is stored in the memory 202 for each water quality standard. The determination unit 220 determines which water quality criterion the water stored in the 1 st water storage tank 111 meets by comparing the results of the tests by the testing device 115 with the respective water quality profiles. That is, the determination unit 220 determines whether or not the water stored in the 1 st water storage tank 111 matches the water quality standard set in the target water storage tank, with two or more 2 nd water storage tanks 112 as the target water storage tanks, respectively.
In step S25, the control unit 230 of the control device 117 instructs the water supply mechanism 114 to supply water from the 1 st water storage tank 111, which is determined by the determination unit 220 to store water that meets the water quality standard set in the 2 nd water storage tank 112, to the 2 nd water storage tank 112. That is, the control unit 230 instructs the water supply mechanism 114 to supply water from the 1 st water storage tank 111 in which water meeting one water quality standard is stored to the 2 nd water storage tank 112 in which the one water quality standard is set. When two or more water quality standards are defined, the control unit 230 instructs the water feed mechanism 114 to feed water from the 1 st water storage tank 111, which is determined by the determination unit 220 to store water that meets the water quality standard, to the 2 nd water storage tank 112, which is set with the water quality standard, for each water quality standard. That is, the control unit 230 sets each of the two or more 2 nd water storage tanks 112 as a target water storage tank, and instructs the water supply mechanism 114 to supply water from the 1 st water storage tank 111, in which water is stored in accordance with the water quality standard set in the target water storage tank, to the target water storage tank. The information indicating the correspondence relationship between the water quality standard and the 2 nd water storage tank 112 is stored in the memory 202 together with the water quality profile and is appropriately referred to by the control unit 230.
In step S26, the control unit 230 instructs the water supply mechanism 114 to supply water from the 1 st water storage tank 111, which has been determined by the determination unit 220 to store water that does not meet the water quality standard set in the 2 nd water storage tank 112, to the 3 rd water storage tank 113. The water delivered to the 3 rd water storage tank 113 is discarded by appropriate treatment after necessary. When two or more water quality standards are defined, the control unit 230 instructs the water supply mechanism 114 to supply water from the 1 st water storage tank 111, which is determined by the determination unit 220 to store water that does not meet any of the water quality standards, to the 3 rd water storage tank 113.
In step S27, the control unit 230 instructs the discharge mechanism 116 to deliver the water stored in the 2 nd water storage tank 112 to the facility 120 at the selling site.
Fig. 6 is a diagram showing the operation of the control device 127 when water is purchased from the sump 110 in a certain facility 120.
In step S31, the control device 127 determines whether the water quality criterion indicated by the water collector 110 is sufficient for the process performed by the equipment 123. If sufficient, the process of step S32 is performed.
In step S32, the control device 127 requests the sump 110 to deliver water, and performs a transaction process for purchasing water at a suitably low price. In the case where two or more water quality standards are defined and different water quality standards are required in two or more steps, water can be purchased at different prices according to the water quality standards. The price of water may be determined from auctions with other facilities 120.
In step S33, the control device 127 instructs the facility 123 to perform a desired process using the water delivered from the sump 110.
Description of effects of embodiments
In the present embodiment, it is determined whether or not water discharged from a certain facility 120 can be supplied to the same facility 120 or another facility 120 based on the result of the water quality inspection. Therefore, introduction of an unnecessary purification apparatus and an unnecessary purification process can be avoided, and effective use of water can be promoted.
According to the embodiment, the precious industrial water can be recycled and saved.
According to the present embodiment, in an industrial area where a plurality of plants are adjacent to each other, the plurality of plants can sell water satisfying one or more water quality standards to the water collector 110, and the plurality of plants can purchase water satisfying one or more water quality standards from the water collector 110 at a low price.
Other constitution
The price of water may be determined as desired, or may be determined as an auction between plants requiring water.
In the case where the demand for water satisfying a certain water quality standard is small, the water quality standard may be changed, or the index of water quality may be changed.
The water quality standard may be added, changed or deleted as necessary.
As a modification, the control device 117 of the water collector 110 may receive demand information indicating a water quality standard requested by one or more facilities 120 from the outside, and adjust the water quality standard set in one or more 2 nd water storage tanks 112 based on the demand information. Specifically, the communication unit 210 of the control device 117 may receive the demand information from the control devices 127 of one or more facilities 120, and the determination unit 220 of the control device 117 may update the water quality profile stored in the memory 202 so as to match the water quality standard indicated by the demand information.
The control device 117 may receive, as the demand information, information indicating a water quality standard requested by the one or more facilities 120, and may receive, as the demand information, information indicating a water amount requested by the one or more facilities 120. Specifically, the communication unit 210 of the control device 117 may receive the demand information from the control device 127 of one or more facilities 120. In this case, the determination unit 220 of the control device 117 may adjust the water quality reference set in the one or more 2 nd water storage tanks 112 according to the amount of water indicated by the demand information. Specifically, a certain step of a certain facility 120 is referred to as "step X", and another step or a certain step of another facility 120 is referred to as "step Y". The water quality standard required in step X is looser than the water quality standard required in step Y, and the amount of water required in step X is significantly smaller than the amount of water required in step Y. In this case, the determination unit 220 may integrate the water quality profile corresponding to the water quality standard required in the step X with the water quality profile corresponding to the water quality standard required in the step Y.
