Is disclosed.

JP-A-8-19773 Japanese Patent Laid-Open No. 10-286033

By the way, the present applicant is studying a new circulating water utilization system that is completely different from the above-described conventional reuse system.
The above-mentioned conventional reuse system basically purifies the drainage of tap water supplied from the water supply network in one building or one household and uses it as middle water for specific purposes. The middle water is discharged into the sewer network. In other words, it is premised on the existence of an existing public water supply network and sewer network, and cannot be a system that replaces this.

  On the other hand, the new circulating water utilization system that the present applicant is examining, as described in detail later, is, for example, up and down with respect to areas and complex facilities where 10,000 people live. This system provides integrated water treatment services, and is a system in which water supply and water treatment are performed cyclically in the area / building. In other words, this circulating water utilization system is basically constructed independently of the existing water supply network and sewerage network, although it is considered that it will be supplied from the water supply only for drinking water for the time being. It is a small-scale distributed water and sewage integrated treatment system.

  In examining such a new circulating water utilization system, how to calculate the usage charge of the circulating water and drinking water was a problem.

  At least one embodiment of the present invention has been made in view of the conventional problems as described above. The purpose of the present invention is to examine the use of circulating water and drinking water when considering a new circulating water utilization system. Another object of the present invention is to provide a billing apparatus suitable for the system for calculating the usage fee.

At least one embodiment of the present invention provides:
Separately from the public water supply network, it is a billing device for a circulating water usage system that is built for a specific area,
The circulating water utilization system is:
A closed loop circulation channel through which the circulating water flows,
Connected to the circulation flow path, and uses the circulating water flowing through the circulation flow path as domestic water, and is composed of a plurality of small water demand bodies consisting of at least one of a residence, a tenant, and an office. A drainage channel for draining the drained water discharged from the water consumer to the circulation channel;
Purification means for purifying the circulating water including the discharged water that is provided in connection with the circulation flow path and flows through the circulation flow path;
A supply flow path that is connected to the circulation flow path and supplies the water that has been purified by the purification means to the water consumer as the domestic water;

A drinking water usage fee calculation unit that calculates a water usage fee.

In conventional charging systems for public water supply and sewerage systems, the amount of water used is directly measured, the amount of sewage is estimated based on the amount of water used, and the amount of water used is determined based on the amount of water used. The usage fee and the sewage usage fee were calculated and charged to the water consumer.
On the other hand, unlike the public water supply and sewage network, the billing device for the above circulating water utilization system is based on the amount of discharged water discharged from the water consumer, not the amount of domestic water supplied to the water consumer. The circulating water usage fee is calculated linearly with respect to the discharged water amount, that is, the usage fee increases as the amount of discharged water increases.

  According to such a billing device of the circulating water utilization system, the usage fee of the circulating water is calculated based not only on the amount of domestic water supplied to the water consumer but on the amount of discharged water. For this reason, the usage charge calculation method is clear, and it is possible to grasp the discharge water from outside the system that cannot be grasped when only the supply amount is measured, so it is possible to construct a more fair charging system. .

  Moreover, in this circulating water utilization system, the tap water supplied from the public water supply network is not provided as it is, but it is further purified and used as drinking water having the same quality as commercially available mineral water. We are considering offering it. Such a mechanism can eliminate the anxiety of people who are reluctant to drink circulating water, and is expected to become a selling point when spreading this circulating water utilization system. is there. Then, the charge for drinking water is calculated based on the excess of the amount of drinking water supplied to each of the small-lot water consumers with the specified amount determined per unit period as the displacement point. Is done. That is, each small-lot water consumer can receive a supply of drinking water free of charge up to a specified amount within a unit period, and an advertising effect can be expected when the circulating water utilization system is spread.

In some embodiments,
The storage tank comprises a potable water tank for supplying potable water to a plurality of the small-bore water consumer,
The potable water supply means is attached to the potable water tank, and has a potable water tank control unit for controlling the supply of potable water from the potable water tank;
The potable water measuring means is configured to measure the potable water supplied from the potable water tank,
The potable water tank control unit is

A permission means for collating the cardholder identification information read by the reading means with the permission identification information stored in advance, and for controlling the availability of drinking water from the potable water tank based on the result of the matching; ,
Updating means for updating the cumulative supply amount information stored in the IC card based on the amount of drinking water supplied from the potable water tank.

  In the above embodiment, the potable water tank control unit reads the card holder identification information and the cumulative supply amount information stored in the IC card, thereby controlling the supply of potable water from the potable water tank. Moreover, a drinking water usage fee calculation unit is mounted on the IC card, and the drinking water usage fee for the small-bore water consumer is calculated on the IC card. Therefore, in the case where drinking water is supplied from a drinking water tank to a plurality of small-bore water consumers, such an IC card is distributed to each of the small-bore water consumers so that each of the small-bore water consumers has drinking water. Usage charges can be calculated.

  In some embodiments, the drinking water supply means includes drinking water pipes for supplying drinking water to each of the small-bore water demand bodies, and the drinking water amount measuring means is provided from the drinking water pipes to the small-bottle water demand bodies. It is comprised so that the amount of drinking water supplied to each of each may be measured.

  According to such an embodiment, the drinking water usage fee for each of the small-mouth water consumer is calculated by measuring the amount of drinking water supplied to each of the small-bottle water consumer by the drinking water meter. I can do it.

The water control valve control unit is configured to open the water control valve.

  According to such an embodiment, when the water cutoff detecting means detects water cutoff in the water supply network, the water control valve control unit opens the water control valve and the purified water is purified from the purified water supply pipe to the purified water generating means. Water is supplied. For this reason, even when the water supply network is shut off, the drinking water generating means can be continuously supplied with water.

In some embodiments,
Tap water monitoring means for monitoring the quality of the tap water;
A shut-off valve capable of shutting off the water supply of the tap water;
A water control valve control unit for controlling opening and closing of the water control valve;

When the tap water monitoring means detects that the quality of the tap water has deteriorated from a prescribed water quality, the water control valve control unit opens the water control valve, and the shutoff valve control unit opens the shutoff valve. Is operated to shut off the water supply of the tap water.

  According to such an embodiment, when the tap water monitoring means detects that the quality of the tap water is worse than the prescribed water quality, the shutoff valve control unit operates the shutoff valve to shut off the tap water supply. At the same time, the water control valve control unit opens the water control valve, and the purified circulating water is supplied from the purified water supply pipe to the purified water generating means. For this reason, even when the quality of the tap water is deteriorated, the drinking water generating means can be continuously supplied with water.

In some embodiments, the circulation channel is not connected to a public sewer network.
According to such an embodiment, water supply and water treatment are performed cyclically in the system, and a completely circulating type of circulating water utilization system that does not discharge sewage outside the system can be constructed.

  In some embodiments, the discharged water amount measuring means is configured to measure the discharged water amount discharged from each of the small-bore water demand bodies, and the circulating water usage charge calculating unit is configured to measure the discharged water amount measuring means. On the basis of the amount of discharged water of each of the small-mouth water demanding bodies measured in step 1, the circulating water usage fee for each of the small-sized water demanding bodies is calculated.

  According to such an embodiment, since the circulating water usage fee is calculated individually based on the amount of discharged water discharged from each of the small-mouth water demanding bodies, the fairness according to the usage record of each small-sized water demanding body is high. It can be a billing system.

  In some embodiments, the discharge water amount measuring unit is configured to collectively measure the amount of discharged water discharged from the entire water demand body, and the circulating water usage charge calculating unit measures in a batch. The circulating water usage fee of the entire water demand body calculated based on the amount of discharged water is assigned to each of the small water demand bodies according to a prescribed rule.

  According to such an embodiment, the discharged water amount measuring means is configured to collectively measure the discharged water amount discharged from the entire water demanding body. Therefore, it is not necessary to measure the amount of discharged water discharged from each of the small-bore water demands, and the discharge water amount measuring means can be composed of, for example, a single flow meter, thereby simplifying the configuration of the discharged water amount measuring means. I can do it.

In some embodiments, the circulating water usage fee calculation unit calculates the circulating water usage fee of the entire water demand body calculated based on the amount of discharged water collectively measured, and the exclusive area in each of the small water demand bodies It is comprised so that it may allocate according to.
The use of domestic water is almost the same in the same kind of small-lot water consumer, and there is a high correlation between the occupied area and the amount of water used among the same kind of small-lot water consumer. In particular, when the water demand body is composed of a collection of the same kind of small water demand bodies, such as an apartment building or an office building, it is expected that the amount of water used for living will increase as the exclusive area increases. Therefore, according to such an embodiment, it is possible to easily calculate the circulating water usage fee of each small-bore water consumer according to the exclusive area.

In some embodiments, the circulating water usage charge calculation unit calculates the circulating water usage charge for the entire water consumer calculated based on the amount of discharged water measured in a lump for each of the small water consumers. It is configured to allocate according to the number of residents or the number of workers in the office.
The use of domestic water is limited in residences and offices, and there is a high correlation between the number of residents and the number of workers and the amount of water used. Therefore, according to such an embodiment, it is possible to simply calculate the circulating water usage fee of each small-bore water consumer according to the number of residents and the number of workers.

In some embodiments, the circulating water usage fee calculation unit calculates the circulating water usage fee of the entire water demand body calculated based on the amount of discharged water collectively measured, and the tenant's industry in each of the small water demand bodies It is comprised so that it may allocate according to.
Even if the exclusive area is the same, tenants have a high correlation between the type of business and the amount of water used so that the amount of water used differs greatly between the restaurant business and the retail industry. Therefore, according to such an embodiment, it is possible to simply calculate the circulating water usage fee of each small-bore water consumer according to the type of business.

<Circulating water use system 1>
FIG. 1 is an overall schematic diagram showing a circulating water utilization system according to at least one embodiment of the present invention.
The circulating water utilization system 1 is a system constructed for a specific area separately from the public water supply network. The population scale targeted by this system is assumed to be approximately 5,000 to 20,000. The target area includes a condominium that is a collection of residences, an office building that is a collection of offices, a commercial facility that is a collection of tenants, and a complex facility in which these are mixed.

  As shown in FIG. 1, the circulating water utilization system 1 includes a circulation channel 2, a water demand body 3, a discharge channel 4, a supply channel 6, a purification unit 8 (purification device), and a charging unit 10 (charging device).

  The circulation channel 2 is configured as a pipe network in which water pipes are arranged in a closed loop shape. Devices such as a pump (not shown) and a valve (not shown) are appropriately arranged in the circulation channel 2 according to the terrain conditions so that the circulating water circulates in one direction.

The water consumer 3 is a main body that uses the circulating water flowing through the circulation channel 2 as domestic water. The water demanding body 3 is constituted by a plurality of small water demanding bodies consisting of at least one of the residence 3a, the tenant 3b, and the office 3c. The dwelling 3a refers to a room in a condominium where one household lives or a detached house. The tenant 3b refers to a store that provides services to general customers in a section of a commercial facility. The business types include, for example, retail stores such as clothing stores, general stores, drug stores, liquor stores, and restaurants, restaurants, cafes, sushi restaurants, taverns, and the like. The office 3c refers to a place where a worker who works in a part of an office building performs office work for a certain purpose.
Examples of the use of domestic water in the residence 3a include showers, baths, washing, washing dishes, washing hands, washing faces, toilets, and the like. Examples of the use of domestic water in the tenant 3b include washing and toilets. Moreover, the amount of water demand varies greatly depending on the type of industry. For example, restaurants use a much larger amount of domestic water than retailers. The use of domestic water in the office 3c is mainly a toilet.

  Moreover, drinking water is supplied to the water consumer 3 separately from the circulating water described above. This drinking water is generated by further purifying tap water introduced from a public water supply network, and has the same quality as commercially available mineral water. Such a mechanism can eliminate the anxiety of those who are reluctant to drink circulating water, and is expected to become a selling point when spreading this circulating water utilization system 1. It is.

The tap water is led from the public water supply network to the drinking water generating means 12 through the tap water conduit 16. The drinking water generating means 12 purifies the introduced tap water and generates drinking water for the water consumer 3. The potable water generating means 12 uses a container-type treatment tank in which a processing device that performs one processing step among a series of purification steps is stored in the container, similarly to the purification means 8 described later. And it is comprised by connecting this container type processing tank in series along the order of a process process.
In addition, in this specification, a container refers to the rectangular container by which the dimension was standardized for the transportation use.

  The potable water generated by the potable water generating means 12 is supplied to each of the small-bore water consumer by the potable water supply means 14. The potable water supply means 14 includes a potable water feed pipe 14a, a storage tank 14b, a potable water pipe 14c, and the like. The potable water generated by the potable water generating means 12 is sent to the storage tank 14b via the potable water supply pipe 14a and temporarily stored in the storage tank 14b. And the drinking water currently stored by the storage tank 14b is supplied to each of the small-lot water demand body which consists of the residence 3a mentioned above, the tenant 3b, and the office 3c via the drinking water piping 14c.

  The discharge channel 4 is a channel for draining the drain water discharged from the water consumer 3 to the circulation channel 2. The discharged water discharged from the discharge flow path 4 includes potable water and other water derived from outside the system in addition to the circulating water used by the water consumer 3 as domestic water. The supply flow path 6 is a flow path for supplying the circulating water purified by the purification means 8 described later to the water consumer 3 as domestic water. Both the discharge flow path 4 and the supply flow path 6 are constituted by pipe lines. Further, the discharge channel 4 and the supply channel 6 are appropriately set according to the terrain conditions so that the discharged water is drained into the circulation channel 2 or the circulating water is supplied to the water demanding body 3. Devices such as a pump (not shown) and a valve (not shown) are arranged.

  The purification means 8 (purification device) is a means for purifying the circulating water including the discharged water flowing through the circulation flow path 2. As will be described later, the purification means 8 uses a container-type treatment tank in which a treatment apparatus that performs one treatment step among a series of purification steps is stored in the container. And it is comprised by connecting this container type processing tank in series along the order of a process process.

  Moreover, in this circulating water utilization system 1, the said circulating water channel 2 is not connected to the public sewer network. As will be described later, surplus sludge such as sludge cake generated in the purification process of discharged water is carried out of the system, but other discharged water is reused 100%. That is, the present circulating water utilization system 1 is a completely circulating circulating water utilization system in which water supply and water treatment are performed cyclically in the system, and sewage is not discharged outside the system.

<Billing means 10>
The billing means 10 (billing device) is a means for calculating the circulating water usage fee and the drinking water usage fee in each of the above-mentioned small-bore water consumers.
The accounting unit 10 includes a discharged water amount measuring unit 18a, a drinking water amount measuring unit 18b, a circulating water usage fee calculation unit 10A, and a drinking water usage fee calculation unit 10B.

  The discharged water amount measuring means 18 a is provided in the above-described discharge flow path 4 and includes a flow meter for measuring the discharged water amount and weight discharged from the water demanding body 3. As shown in FIG. 4, the discharged water amount measuring means 18a includes a plurality of flow meters 18a1 so as to measure the discharged water amount discharged from each of the small water demanding bodies such as the residence 3a, the tenant 3b, and the office 3c. , 18a2. Moreover, as shown in FIG. 5, you may be comprised from one flowmeter 18a1 so that the amount of discharged water discharged | emitted from the whole water demand body 3 may be measured collectively.

  The drinking water amount measuring means 18b is provided on the downstream side of the storage tank 14b of the drinking water supply means 14 described above, and includes a flow meter 18b that measures the amount of drinking water supplied to each of the small-bore water consumers. .

  The circulating water usage charge calculation unit 10A and the drinking water usage charge calculation unit 10B are a microcomputer including a central processing unit (CPU), a random access memory (RAM), a read only memory (ROM), an I / O interface, and the like. It is configured. And according to the calculation logic shown in FIG.2 and FIG.3, it is comprised so that a circulating water usage fee and a drinking water usage fee may be calculated, respectively.

  FIG. 2 is a diagram showing the calculation logic of the circulating water usage fee in the circulating water usage fee calculation unit. As shown in FIG. 2, the circulating water usage fee calculation unit 10A calculates the circulating water usage fee by multiplying the amount of discharged water by the circulating water unit usage fee. With this calculation logic, the circulating water usage fee is calculated linearly with respect to the amount and weight of the discharged water, that is, the usage fee increases as the amount of discharged water increases.

  According to the billing means 10 (billing device) of the circulating water utilization system 1 as described above, the usage fee of the circulating water is calculated based not on the amount of domestic water supplied to the water demand body 3 but on the amount of discharged water. For this reason, the usage charge calculation method is clear, and it is possible to grasp the discharge water from outside the system that cannot be grasped when only the supply amount is measured, so it is possible to construct a more fair charging system. .

  FIG. 3 is a diagram showing the calculation logic of the drinking water usage fee in the drinking water usage fee calculation unit. As shown in FIG. 3, in the drinking water usage fee calculation unit 10B, the prescribed amount determined per unit period is used as a displacement point, and the amount of drinking water supplied to each of the small-bore water consumers is relative to the prescribed amount. Multiply the excess by the drinking water unit usage fee to calculate the drinking water usage fee. That is, each small-lot water consumer can receive drinking water for free up to a specified amount within a unit period. With such a mechanism, it is possible to expect an advertising effect when the circulating water utilization system 1 is spread.

FIG. 6 is a diagram showing a billing process flow in the case of measuring the amount of discharged water discharged from each of the small-bore water consumers. In this case, first, the amount of discharged water discharged from each of the small water demanding bodies such as the residence 3a, the tenant 3b, and the office 3c is measured by the plurality of flow meters 18a1 and 18a2 shown in FIG. 4 (S61). ). And then, multiply the measured water discharge amount of each small water consumer by the circulating water unit usage fee (for example, 400 yen / m ^ 3) to calculate the circulating water usage fee of each small water consumer. (S62). Finally, the calculated circulating water usage fee is charged for each of the small-lot water demanding bodies (S63).
According to such an embodiment, since the circulating water usage fee is calculated individually based on the amount of discharged water discharged from each of the small-mouth water demanding bodies, the fairness according to the usage record of each small-sized water demanding body is high. It can be a billing system.

FIG. 7 is a diagram showing a flow of a billing process in a case where the amount of discharged water discharged from the entire water consumer is measured collectively. In this case, first, the amount of discharged water discharged from the entire water demand body 3 is collectively measured by one flow meter 18a1 shown in FIG. 5 (S71). Next, the circulating water usage fee for the entire water demand body 3 is calculated by multiplying the measured amount of discharged water of the entire water demand body 3 by a circulating water unit usage fee (for example, 400 yen / m ^ 3) (S72). Then, the circulating water usage charge for the entire small water demand body 3 is multiplied by the apportioning ratio of each small water demand body calculated in accordance with the rules defined in step S73. Are calculated respectively (S74). Finally, the calculated circulating water usage fee is charged for each of the small-lot water demanding bodies (S75).
According to such an embodiment, it is not necessary to measure the amount of discharged water discharged from each of the small-bore water demands, and the discharged water amount measuring means 18a can be constituted by, for example, one flow meter 18a1. The configuration of the water amount measuring means 18a can be simplified.

  As an example of the setting method of each apportioning ratio of the small-lot water demanding body in the above step S73, setting the apportioning ratio according to the exclusive area ratio occupied by each of the small-lotting water demanding body can be mentioned. For example, the apportionment ratio can be set as the ratio of the exclusive area of each small-lot water demanding body to the total area of the target facility, region, etc. of this system (exclusive area / total area). The use of domestic water is almost the same in the same kind of small-lot water consumer, and there is a high correlation between the occupied area and the amount of water used among the same kind of small-lot water consumer. In particular, when the water demand 3 is composed of a collection of the same kind of small-volume water demand bodies, such as condominiums and office buildings, it is expected that the amount of water used for living will increase as the exclusive area increases. . Therefore, according to such an embodiment, it is possible to easily calculate the circulating water usage fee of each small-bore water consumer according to the exclusive area.

  Moreover, as another example of the setting method of each apportioning ratio of each small water demand body in said step S73, according to the number of residents of the residence 3a in each small water demand body or the number of workers of the office 3c One example is setting a proration rate. For example, the distribution ratio can be set as the ratio of the number of constituents of each small water consumer with respect to the total number of persons targeted by the present system (the number of constituents / the total number of persons). In the residence 3a and the office 3c, the use of daily water is limited, and there is a high correlation between the number of residents and the number of workers and the amount of water used. Therefore, according to such an embodiment, it is possible to simply calculate the circulating water usage fee of each small-bore water consumer according to the number of residents and the number of workers.

  Moreover, as another example of the setting method of each apportioning ratio of each small water demand body in said step S73, setting the apportioning ratio according to the type of business of the tenant in each of the small water demanding bodies can be mentioned. Even if the exclusive area is the same, tenants have a high correlation between the type of business and the amount of water used so that the amount of water used differs greatly between the restaurant business and the retail industry. Therefore, an industry coefficient Y is set for each industry, for example, a high industry coefficient (for example, Y1 = 1.2) is set for industries with a large amount of water used, such as restaurants, etc. Is set to a low industry coefficient (for example, Y3 = 0.8), and the apportionment ratio is set taking the industry coefficient into consideration. Therefore, according to such an embodiment, it is possible to simply calculate the circulating water usage fee of each small-bore water consumer according to the type of business.

  FIG. 8 is a partial schematic diagram showing a circulating water utilization system in the case where drinking water is supplied to each of the small-bore water consumers through drinking water piping. In this case, as shown in FIG. 8, the drinking water amount measuring means 18b measures the amount of drinking water supplied to each of the small-lot water demanding bodies such as the dwelling 3a, the tenant 3b, and the office 3c. The drinking water pipes 14c1 and 14c2 are provided with flow meters 18b1 and 18b2, respectively.

FIG. 9 is a partial schematic diagram showing a circulating water utilization system in the case where drinking water is supplied to a plurality of small-bore water consumers by means of a drinking water tank. In this embodiment, the storage tank 14b includes a potable water tank 14b for supplying potable water to a plurality of small-bore water demanding bodies. And drinking water is supplied with respect to a some small water demand body from faucet 14d of potable water tank 14b. One flow meter 18b1 is attached to the faucet 14d as the drinking water amount measuring means 18b, and is configured to measure the amount of drinking water supplied from the drinking water tank.
In this case, the potable water supply means 14 includes a potable water supply pipe 14a, a potable water tank 14b, a faucet 14d, and a potable water tank control unit 20 that controls the supply of potable water from the potable water tank 14b. The drinking water supply control in the drinking water tank control unit 20 is performed based on the identification information stored in the IC card held by each of the small-sized consumer bodies.

FIG. 10 is a block diagram for explaining functional configurations of the drinking water tank control unit and the IC card. As shown in FIG. 10, the IC card 20a held by each of the small-bore water consumers has card holder identification information for identifying the holder of the IC card 20a and the unit period described above. The cumulative supply amount information relating to the cumulative amount of drinking water supplied from the drinking water tank 14b to the IC card holder is stored. In addition, the above-described drinking water usage fee calculation unit 10B is mounted on the IC card 20a.
The potable water tank control unit 20 also has a reading means 20A that can read the cardholder identification information and cumulative supply amount information, and a permission means 20B that controls whether or not potable water can be supplied from the potable water tank 14b. And update means 20C for updating the accumulated supply amount information stored in the IC card 20a.

  FIG. 11 is a diagram showing a flow of drinking water supply control in the drinking water tank control unit. First, the reading means 20A composed of an IC card reader or the like reads card holder identification information and accumulated supply amount information stored in the IC card 20a (S111). Then, the permission unit 20B collates the read card holder identification information with the permission identification information stored in advance (S112). And based on this collation result, the possibility of the supply of the drinking water from the drinking water tank 20 is determined, and if it can be supplied, the drinking water is supplied (S113). When the supply is impossible, the drinking water is not supplied (S114). When drinking water is supplied, the supplied drinking water amount is instantly grasped by the drinking water amount measuring means 18b, and the card holder identification information and the accumulated supply amount information are mounted on the IC card 20a. It is transmitted to the potable water usage fee calculation unit 10B (S115). Then, the update means 20C updates the accumulated supply amount information stored in the IC card (S116).

  FIG. 12 is a diagram showing a flow of a billing process in the potable water usage fee calculation unit. First, information on the latest cumulative supply amount including the drinking water supply amount measured by the drinking water measuring unit 18b is received (S121). Then, it is determined whether or not the cumulative supply amount exceeds the prescribed amount (S122). If the cumulative supply amount exceeds the prescribed amount, the excess amount with respect to the prescribed amount is set as the billed water amount, and the drinking water unit usage fee (for example, 100,000 yen / m ^) By multiplying 3), the circulating water usage charge of the small-lot water consumer is calculated (S123). Finally, the calculated circulating water usage fee is charged for the small-bore water consumer (S124). On the other hand, if the updated updated cumulative supply amount does not exceed the prescribed amount, the charging process is not performed (S125).

  In the above embodiment, the potable water tank control unit 20 reads the card holder identification information and the cumulative supply amount information stored in the IC card 20a, thereby controlling the supply of potable water from the potable water tank 14b. In addition, the IC card 20a is provided with a drinking water usage fee calculation unit 10B, and the drinking water usage fee for the small-bore water consumer is calculated on the IC card. Therefore, when supplying drinking water from the drinking water tank 14b to a plurality of small-bore water consumers, by distributing such an IC card 20a to each of the small-bore water consumers, each of the small-bore water consumers is provided. Drinking water usage charges can be calculated.

  In addition to or in addition to the billing by the IC card 20a described above, the supply of potable water may be controlled by a prepaid card. That is, by holding the prepaid card over the potable water tank control unit 20, the potable water may be supplied from the potable water tank 14b, and the remaining amount of the prepaid card may be reduced by the supplied amount. Billing with such a prepaid card is particularly effective when drinking water is supplied to other than the small consumer.

  In addition, arrangement | positioning and a structure of the processing tank of the purification | cleaning means 8 and the drinking water production | generation means 12 mentioned above are examples, Comprising: It can change variously according to the quality of the drained waste water, and the target purification level. Moreover, the code | symbol TW in a figure has shown the flow of the tap water supplied from a public water supply network. The tap water TW may be configured not only to be supplied to the drinking water generating means 12 as described above, but also to be supplied to the circulation channel 2 as make-up water as necessary. The supply position in this case is preferably on the downstream side of the fine membrane container L5 where the purification process of the discharged water is almost completed. Moreover, the code | symbol WW4 in a figure is a return pipeline for sending concentrated water to the screen / flow control container L1.

Thus, in the new circulating water utilization system 1 which the present applicant is examining, the purification means 8 for purifying the discharged water and the drinking water generation means 12 for purifying the tap water have three or more series of purification steps. A container-type processing tank is used in which a processing apparatus that performs one of the processing steps is stored in the container. Then, a container-type processing tank that performs the first processing step, a container-type processing tank that performs the next processing step, and a container-type processing tank that performs the subsequent processing steps are brought into the field, and each is connected in series with a connecting pipe. The purifying means 8 is constructed by connecting to. Such a container-type treatment tank is excellent in portability because it can be loaded and transported on a truck as it is. Moreover, since it is detachably accommodated in the container container, it can be installed and removed freely.
In the following description, a container-type treatment tank constituting the purification means 8 will be described as an example, but the present invention can also be applied to a container-type treatment tank constituting the drinking water generating means 12.

  The processing capacity per processing tank of the container-type processing tank is assumed to be a scale capable of processing about 1,000 people of discharged water. For this reason, for example, when this circulating water utilization system is introduced to an area or complex facility where 10,000 people live, a plurality of (for example, 10) treatment tanks that perform the same treatment process are required. Become. Thus, by providing a plurality of processing tanks that perform the same processing step, the processing capacity per processing tank can be reduced. Therefore, it is possible to flexibly cope with population fluctuations and water demand seasonal fluctuations in the target area. Moreover, it is easy to prepare an alternative processing tank, and the maintenance is excellent.

  Here, among the treatment tanks up to L1-L8 for performing a series of purification steps for purifying the discharged water, any treatment tank (for example, L3) is the next of the treatment process performed in the first treatment tank and the first treatment tank. A processing tank (for example, L4) that performs the processing process is referred to as a second processing tank, and a processing tank (for example, L5) that performs the next processing process of the processing process performed in the second processing tank is referred to as a third processing tank. The first processing tank, the second processing tank, and the third processing tank are each a plurality, the plurality of first processing tanks being a first processing tank group, the plurality of second processing tanks being a second processing tank group, The plurality of third treatment tanks will be referred to as a third treatment tank group, respectively.

FIG. 14 is a schematic view showing a first processing tank, a second processing tank, a third processing tank, and a container container that stores them. FIG. 15 is a schematic diagram for explaining a connection mode of the first processing tank, the second processing tank, and the third processing tank.
As shown in FIG. 14, each of the first processing tank 41, the second processing tank 42, and the third processing tank 43 is detachably accommodated in the container container 50. The first processing tank 41 and the second processing tank 42 are connected by a first-second connecting pipe 44. Further, the second processing tank 42 and the third processing tank are connected by a 2-3 connecting pipe 45.

  And as shown in FIG. 15, in the said 1-2 connection pipe 44 and the 2-3 connection pipe 45, any one of the pipe diameter of a connection part, a joint structure, and piping color differs. . In the embodiment shown in FIG. 15 (a), the pipe diameter of the first-second connecting pipe 44a is formed larger than the pipe diameter of the second-third connecting pipe 45, and both pipe diameters are different. Yes. In the present invention, an aspect in which the pipe diameter of the first-second connecting pipe 44a is the same as the pipe diameter of the second-third connecting pipe 45 and only the pipe diameter of the connecting portion is changed by an adapter. It is contained in the aspect from which the pipe diameter of a connection part differs. In the embodiment shown in FIG. 15B, the joint structure of the first-second connecting pipe 44b is an insertion joint, and the joint structure of the second-third connecting pipe 45b is a flange joint.

In the second and third connecting pipes 45 to be connected to each other, at least one of the pipe diameter of the connecting portion, the joint structure, and the pipe color is configured to be different, and erroneous piping between different types of processing tanks is performed. It is preventing.

In the above embodiment, preferably, in addition to the pipe color, either the pipe diameter or the joint structure is different. Although the piping color serves as an identification mark, it does not physically prevent erroneous piping. On the other hand, if any one of the pipe diameter and the joint structure is different, erroneous piping between different types of treatment tanks can be physically prevented.
Moreover, in the said embodiment, an adapter is connected with respect to the 1-2 connection pipe or the 2-3 connection pipe, and it enables connection with respect to a different pipe diameter, for example, a 1st processing tank and a 3rd process. It is possible to flexibly handle special combinations such as connecting a tank.

The domestic water volume measuring means 18c includes, for example, a flow meter 18c. Then, the daily water amount measured by the domestic water amount measuring unit 18c is memorized every moment, and the future water demand for domestic water is predicted based on the stored past daily water amount. Has been.

As a method for predicting water demand, the amount of domestic water supplied in the same month, day, day of the week, time zone, etc. in the past can be used as a predicted value of water demand. Moreover, the predicted value of water demand can also be corrected based on outside air information such as temperature and humidity.
According to such an embodiment, since the purification means 8 can be appropriately driven according to the prediction result of the water demand, the purification means 8 can be operated efficiently.

  As mentioned above, although the preferable form of this invention was demonstrated, this invention is not limited to said form. For example, the above-described embodiments may be combined, and various modifications can be made without departing from the object of the present invention.

  For example, in the description of the above-described embodiment, the plurality of water treatment tanks constituting the purification means 8 and the potable water generation means 12 are configured as container-type water treatment tanks whose treatment devices are stored inside the container. It was. However, in the novel circulating water utilization system 1 described above, the form of the water treatment tank is not limited to this. As with the container, the water treatment tank may be configured by storing the treatment device inside a container other than the container as long as it is portable, easy to handle, and easily removable. .

  At least one embodiment of the present invention can be suitably used in a circulating water utilization system constructed for a specific area separately from a public water supply network.
