Embodiment approach 1

[0029] use Figure 1 to Figure 6 , and this embodiment will be described.

[0030] ***Description of Composition***

[0031] refer to figure 1 , the configuration of the water circulation system 100 of this embodiment will be described.

[0032] The water circulation system 100 can be built in any place or region, and in this embodiment, it is built in an industrial area. It should be noted that the water circulation system 100 can also be constructed across more than two industrial areas.

[0033] The water circulation system 100 has a water collector 110 and two or more facilities 120 that utilize water.

[0034] As a specific example, each facility 120 is a factory in an industrial zone. The number of facilities 120 may be any number, and it is eight in this embodiment. It should be noted that the facility 120 does not need to be a factory in the same industrial zone.

[0035] The water used in each facility 120 is supplied or discharged to the same facility 120 or o...

Abstract

In a water aggregator (110), a first water storage tank (111) is a water storage tank for storing water discharged from at least one facility (120) that uses water. A second water storage tank (112) is a water storage tank for storing water to be supplied to at least one facility (120). A testing device (115) is a device for testing the water quality of the first water storage tank (111). A control device (117) determines, on the basis of the test results of the testing device (115), whether or not the water stored in the first water storage tank (111) meets the water quality standards set forthe second water storage tank (112) and if the standards are met, instructs a water supply mechanism (114) to send water from the first water storage tank (111) to the second water storage tank (112).

Description

technical field [0001] The present invention relates to a water aggregator, a water circulation system, a control device, a control method and a control program. Background technique [0002] Due to recent climate changes, some areas are frequently hit by heavy rains, while some areas have been drought for many years, and water resources are becoming more and more precious every year. In particular, industrial water has a lower priority than agricultural water, so it is expected to become more and more expensive and the price will increase. Therefore, in terms of industrial use, it is considered that rather than purchasing purified water, it is more often preferable to recycle water at a certain cost. [0003] Patent Document 1 discloses a circulating water utilization system, which has: a purifying device that purifies circulating water including drain water flowing in a circulating flow path in stages through two or more water quality grades; and a supply device , which ...
