<Explanation of collection information DB>
FIG. 5 is a diagram showing an example of the collection information DB 114.
In the illustrated example, information is stored for each item of "provider identification information", "amount of collected laundry wastewater", "collection date and time", and "price". The "provider identification information" is the provider identification information of the provider who provided the laundry wastewater. "Amount of laundry wastewater collected" is the amount of laundry wastewater collected from the provider. The "collection date and time" is the date and time when the laundry wastewater was collected. The "price" is the amount of the price paid to the provider according to the collected laundry wastewater.

For example, it shows that the laundry wastewater was collected from 10:00 to 11:00 on October 1, 2019 for the provider of "provider AAA". The amount of laundry wastewater collected at that time is 1000 liters, which indicates that 100 yen will be paid to the provider of "provider AAA". In addition, in this example, it is predetermined to purchase for 0.1 yen per liter of washing wastewater. Therefore, the price paid to the provider is 100 yen. In addition, regarding the provider of "provider AAA", the laundry wastewater is also collected from 10:00 to 11:00 on October 2, 2019, and the amount of laundry wastewater collected at that time is 1000 liters, the provider. The price paid to is 100 yen.
Similarly, various information is stored for each provider such as "provider BBB", "provider CCC", and "provider DDD".

In this way, the collection information DB 114 stores the provider identification information, the amount of collected laundry wastewater, the collection date and time, and the information of the price paid to the provider in association with each other.
The information stored in the collection information DB 114 is not limited to the example shown in FIG. For example, the collection information DB 114 may store information on the vacuum car that collected the laundry wastewater, information on the collection company that collected the laundry wastewater, and the like.

In addition, the collection information DB 114 may store the information of the vacuum car that collected the washing wastewater, and manage the washing wastewater information for each vacuum car. For example, the collection information association unit 113 stores the amount of laundry wastewater collected from the provider and the provider identification information of the provider in the collection information DB 114 for each vacuum car. More specifically, the identification information for identifying the vacuum car, the amount of washing wastewater collected by the vacuum car from the provider, and the provider identification information of the provider are stored in association with each other. As a result, for example, for each vacuum car, it becomes possible to grasp how much laundry wastewater was collected from what kind of provider.
Here, a vacuum car is used as an example of a collection unit that collects wastewater from a provider.

<Explanation of purchase request information DB>
FIG. 6 is a diagram showing an example of the purchase request information DB 124.
The example shown in FIG. 6 (A) is an example in the case where the purchase applicant is a farmer. The purchase request information DB 124 stores information about each item of "purchase applicant identification information", "purchase desired laundry drainage amount", "scheduled delivery date and time", and "price". "Purchase applicant identification information" is purchase applicant identification information of a purchase applicant who wishes to purchase laundry wastewater. The "amount of laundry wastewater desired to be purchased" is the amount of laundry wastewater desired to be purchased by the purchaser. The "scheduled delivery date and time" is the date and time when the laundry drainage is scheduled to be provided to the purchase applicant. The "price" is the amount of the price received from the purchase applicant.

For example, it indicates that laundry drainage will be provided to those who wish to purchase "Purchase AAA" from 13:00 to 14:00 on October 1, 2019. The amount of laundry wastewater provided at that time is 1000 liters, which indicates that 300 yen will be received from the purchase applicant of "Purchase applicant AAA". In addition, in this example, it is predetermined that the laundry wastewater will be sold for 0.3 yen per liter. Therefore, the price received from the purchase applicant is 300 yen. In addition, for those who wish to purchase "AAA", laundry drainage is scheduled to be provided from 16:00 to 17:00 on October 2, 2019, and the amount of laundry drainage provided at that time is 2000 liters. , Indicates that the price received from the purchase applicant is 600 yen.
Similarly, various information is stored for each purchase applicant such as "purchase applicant BBB", "purchase applicant CCC", and "purchase applicant DDD".

Further, the example shown in FIG. 6B is an example in the case where the purchase applicant is an exporter. Since this purchaser delivers the laundry wastewater to a foreign country by a tanker, the amount of the purchaser wants to purchase is much larger than that in the example shown in FIG. 6 (A). For example, it indicates that laundry drainage will be provided to those who wish to purchase "Purchase XXX" from 13:00 to 17:00 on October 10, 2019. The amount of laundry wastewater provided at that time is 10,000 kiloliters, indicating that it will receive 3 million yen from those who wish to purchase it.

As described above, in the purchase request information DB 124, information on the purchase applicant identification information, the amount of laundry wastewater desired to be purchased by the purchase applicant, the scheduled delivery date and time, and the price received from the purchase applicant are stored in association with each other.
The information stored in the purchase request information DB 124 is not limited to the example shown in FIG. For example, in the purchase request information DB 124, the date and time when the laundry drainage was actually provided, the amount of the laundry drainage actually provided, the information of the water truck that provided the laundry drainage, and the laundry drainage were provided. The information of the person may be stored.

<Procedure for collecting laundry wastewater>

Next, the collection information association unit 113 stores the collected washing wastewater information in the collection information DB 114 in association with each other (S102). For example, the provider identification information, the amount of laundry wastewater collected from the provider, and the collection date and time information are stored in association with each other.

Next, the payment price calculation unit 115 calculates the price to be paid to the provider according to the amount of the collected laundry wastewater (S103). The price information calculated here is also stored in the collection information DB 114. Next, the provider notification unit 116 notifies the provider of the amount of the collected laundry wastewater and the price to be paid to the provider (S104). Then, this processing flow ends.

<Procedure for selling laundry wastewater>
FIG. 8 is a flowchart showing an example of a procedure for selling laundry wastewater. As an initial state, it is assumed that the purchase applicant is registered and the purchase applicant identification information is prepared for the purchase applicant. Further, in the following, the processing step is referred to as the symbol “S”.

First, when a purchase applicant inputs information on a purchase request for laundry wastewater into the purchase applicant terminal 400, the input information is transmitted from the purchase applicant terminal 400 to the management server 100. Then, the purchase request information acquisition unit 122 acquires the purchase request information of the washing wastewater (S201). Next, the purchase request information association unit 123 stores the purchase request information of the washing wastewater in the purchase request information DB 124 in association with each other (S202). For example, the purchase applicant identification information, the amount of laundry wastewater desired to be purchased, and the date and time information desired to deliver the laundry wastewater are stored in association with each other.

Next, the receipt price calculation unit 125 calculates the price received from the purchase applicant according to the amount of laundry wastewater that the purchase applicant desires to purchase (S203). The price information calculated here is also stored in the purchase request information DB 124. Next, the sales schedule creation unit 126 creates a schedule such as the date and time for delivering the laundry wastewater to the purchase applicant (S204). Next, the purchase applicant notification unit 127 notifies the purchase applicant of the date and time when the laundry wastewater is scheduled to be delivered and the price received from the purchase applicant (S205). Then, this processing flow ends.

<Examples of collection and sale of laundry wastewater>
Next, the collection and sale of laundry wastewater will be described with reference to examples. FIG. 9 is a diagram for explaining an embodiment of collection and sale of laundry wastewater. In the example shown in FIG. 9, it is assumed that the laundry wastewater is collected from the provider A and the laundry wastewater is sold to the purchase applicant B.

First, a case where the laundry wastewater is collected from the provider A will be described with reference to FIG. 9 (A).
Provider A registers as a provider as a preliminary treatment for collecting laundry wastewater. By registering as a provider, the provider identification information of the provider A is prepared. In this example, the provider registration reception unit 111 assigns the provider identification information "provider AAA" to the provider A. However, as the provider identification information, information such as the name, address, and contact information of the provider A may be used.
Further, the provider A is washing the laundry using the magnesium material, and the washing drainage of the washing is stored in the tank 601 through the drain pipe. The drainage pipe here is configured so that the washing drainage and other drainage (for example, the drainage of a washroom or a toilet) are not mixed.
In addition, for example, provider A has entered into a contract with a distributor of laundry wastewater to use magnesium materials in laundry. In other words, the contract is made not to wash with detergents other than magnesium materials.

Here, the collector goes to the place where the tank 601 of the provider A is provided, for example, on a regular basis (for example, every week) by the vacuum car 602. Then, the washing wastewater is sucked from the tank 601 and the washing wastewater is collected. At that time, the amount of the collected washing wastewater is measured by the measuring device 603. In the illustrated example, the measuring instrument 603 is attached to the hose of the vacuum car 602, but the position of the measuring instrument 603 is not limited. For example, the measuring instrument 603 may be attached to the rear portion of the vacuum car 602 or may be attached to the side surface portion of the vacuum car 602.
When collecting the washing wastewater, the washing wastewater may be passed through a filter to remove dust and impurities contained in the washing wastewater.

Next, the collection company inputs the information on the washing wastewater collected from the provider A into the collection company terminal 300. The input information is transmitted from the collection company terminal 300 to the management server 100. Specifically, for example, the amount of collected laundry wastewater, the provider identification information of the provider A, and the information on the date and time when the collection was performed are transmitted to the management server 100. In this example, it is assumed that 1000 liters of laundry wastewater is collected from the provider A from 13:00 to 14:00 on October 1, 2019.

Here, the collection company terminal 300 may transmit information such as the amount of collected laundry wastewater to the management server 100 without the operation of the collection company. For example, when the collection of the laundry wastewater is completed, the collection company terminal 300 transfers the position information acquired by the GPS (Global Positioning System) sensor provided in the collection company terminal 300 and the amount of the collected laundry wastewater to the management server 100. Send. The management server 100 searches the address list of the provider registered in advance, and searches for the address corresponding to the location information acquired from the collection company terminal 300. In this example, the address of the provider A is searched for as the address corresponding to the location information. Therefore, the provider of the laundry wastewater is identified as the provider A. As a result, the management server 100 stores the collected amount of laundry wastewater in the collection information DB 114 in association with the provider identification information of the provider A.

Further, in this example, the management server 100 has searched for the address corresponding to the location information from the address list of the provider registered in advance, but the collection company terminal 300 may perform this process. For example, the collection company terminal 300 stores a list of addresses of the providers in advance. Then, the collection company terminal 300 searches for the address corresponding to the location information from the address list of the provider. In this example, the address of the provider A is searched for as the address corresponding to the location information. Therefore, the provider of the laundry wastewater is identified as the provider A. Then, the collection company terminal 300 transmits the amount of the collected laundry wastewater and the provider identification information of the provider A to the management server 100. The provider identification information here is, for example, the address of the provider A. Further, when information such as the name of the provider A is stored in the collection company terminal 300, the name of the provider A may be transmitted as the provider identification information.
Note that a device other than the collection company terminal 300, such as a computer device provided in the vacuum car 602, may transmit various information to the management server 100.

Next, the collection information acquisition unit 112 acquires information on the laundry wastewater collected from the provider A from the collection company terminal 300. Next, the collection information association unit 113 stores the information of the washing wastewater collected from the provider A in the collection information DB 114 in association with each other. For example, the amount of washing wastewater collected from the provider A (1000 liters in this example), the provider identification information "provider AAA", and the date and time when the collection was performed (in this example, 13:00 on October 1, 2019). ~ 14:00) is associated and stored in the collection information DB 114.

Next, the payment price calculation unit 115 calculates the price to be paid to the provider A according to the amount of the washing wastewater collected from the provider A. In this example, the amount of laundry wastewater collected from provider A is 1000 liters. Further, as a charge for washing wastewater, it is predetermined that the washing wastewater is collected at a charge lower than the charge for tap water (for example, half of the water charge). Specifically, it is predetermined to purchase for 0.1 yen per liter of washing wastewater. Therefore, the price paid to the provider A is calculated as "100 yen".

Next, the provider notification unit 116 pays the provider terminal 200 of the provider A the amount of laundry wastewater collected (1000 liters in this example) and the price paid to the provider A (100 yen in this example). ) Is notified.
The time to pay the price to the provider A is not limited. For example, the price may be paid when the laundry wastewater is collected from the provider A, or the price of the laundry wastewater collected from the provider A for a certain period (for example, one month) may be paid in a lump sum at a later date.
Further, the washing wastewater collected from the provider A is carried to the water storage warehouse 604 by the vacuum car 602 and stored in the water storage warehouse 604. In this way, the laundry wastewater is collected.

Next, a case where the laundry wastewater is sold to the purchase applicant B will be described with reference to FIG. 9B.
The purchase applicant B registers as a purchase applicant as a preliminary process for purchasing the laundry wastewater. By registering as a purchase applicant, the purchase applicant identification information of the purchase applicant B is prepared. In this example, the purchase applicant registration reception unit 121 assigns the purchase applicant identification information “purchase applicant BBB” to the purchase applicant B. However, information such as the name, address, and contact information of the purchase applicant B may be used as the purchase applicant identification information.
In addition, the laundry wastewater collected from various providers is stored in the water storage warehouse 604.

Next, when the purchase applicant B operates the purchase applicant terminal 400 and inputs the information of the purchase request of the laundry wastewater, the purchase request information acquisition unit 122 acquires the information of the purchase request of the laundry wastewater. Specifically, for example, the amount of laundry wastewater that the purchaser B wants to purchase, the purchaser identification information of the purchaser B, and the date and time information that the purchaser B wants to deliver the laundry wastewater are acquired. In this example, it is assumed that the purchase applicant B wants to purchase 2000 liters of laundry wastewater and have it delivered from 16:00 to 17:00 on October 2, 2019.

Next, the purchase request information mapping unit 123 stores the purchase request information by the purchase requester B in the purchase request information DB 124 in association with each other. Here, the amount of washing wastewater that the purchase applicant B wants to purchase (2000 liters in this example), the purchase applicant identification information "purchase applicant BBB", and the date and time when the purchase applicant B wants to deliver the laundry wastewater (in this example, The information of October 2, 2019 (16:00 to 17:00) is associated and stored in the purchase request information DB 124.

Next, the receipt price calculation unit 125 calculates the price received from the purchase applicant B according to the amount of laundry wastewater that the purchase applicant B desires to purchase. In this example, the amount of washing wastewater that the purchase applicant B desires to purchase is 2000 liters. In addition, it is predetermined that the laundry wastewater will be sold at a higher rate than the tap water fee. Specifically, it is predetermined that the product will be sold for 0.3 yen per liter of laundry wastewater. Therefore, the price received from the purchase applicant B is calculated as "600 yen".

Next, the sales schedule creation unit 126 creates a schedule such as a date and time for delivering the laundry wastewater to the purchase applicant B. For example, the sales schedule creation unit 126 determines the amount of laundry wastewater that the purchaser B wants to purchase, the date and time that the purchaser B wants to deliver the laundry wastewater, the storage status of the laundry wastewater in the water storage warehouse 604, and the water truck 605. The date and time for delivering the laundry wastewater is determined based on the availability of the water storage warehouse 604 and the distance (or travel time) between the water storage warehouse 604 and the delivery destination (for example, the location of the tank 606 of the purchase applicant B).

More specifically, for example, the travel time from the water storage warehouse 604 to the delivery destination is set to 1 hour. Here, since the date and time when the purchase applicant B desires the delivery of the laundry wastewater is from 16:00 to 17:00 on October 2, 2019, the time when the water truck 605 should depart from the water storage warehouse 604 is October 2019. It is said to be 15:00 on the 2nd. Around this time, if the desired amount of 2000 liters is to be stored in the water storage warehouse 604 and the water truck 605 is scheduled to be vacant, the water truck 605 will be installed on October 2, 2019 15 Sometimes it is possible to leave. Therefore, the sales schedule creation unit 126 determines that the laundry wastewater can be delivered to the purchase applicant B from 16:00 to 17:00 on October 2, 2019, which the purchase applicant B desires.
On the other hand, for example, if there is no plan to store 2000 liters in the water storage warehouse 604 around 15:00 on October 2, 2019, the date and time will be changed. Here, if the amount of water stored in the water storage warehouse 604 is scheduled to exceed 2000 liters around 10 o'clock on October 3, 2019, and the water tanker 605 is scheduled to be vacant at that time, the water tanker 605 is scheduled to be vacant. It is possible to depart at 10:00 on October 3, 2019. Therefore, the sales schedule creation unit 126 determines that the laundry wastewater can be delivered to the purchase applicant B from 11:00 to 12:00 on October 3, 2019.

Next, the purchase applicant notification unit 127 sends the purchase applicant terminal 400 of the purchase applicant B the date and time when the laundry wastewater is scheduled to be delivered and the price received from the purchase applicant B (600 yen in this example). Notice.
Then, the washing drainage is replenished from the water storage warehouse 604 to the water supply vehicle 605, and the water supply vehicle 605 moves to the delivery destination. When the water truck 605 arrives at the delivery destination, the water truck 605 provides the washing drainage to the tank 606 of the purchase applicant B. At that time, the amount of washing wastewater provided is measured by the measuring instrument 607. In the illustrated example, the measuring instrument 607 is attached to the hose of the water truck 605, but the position of the measuring instrument 607 is not limited. For example, the measuring instrument 607 may be attached to the rear part of the water truck 605 or may be attached to the side surface portion of the water truck 605.

When the amount of washing wastewater provided to the tank 606 of the purchase applicant B reaches 2000 liters, the provision ends. Here, if there is an error between the desired purchase amount of the purchase applicant B (that is, 2000 liters) and the amount of the laundry wastewater actually provided (that is, the amount measured by the measuring instrument 607), it is actually The price received from the purchase applicant B may be recalculated according to the amount of laundry wastewater provided to.
The time to receive the price from the purchase applicant B is not limited. For example, the price may be received when the laundry wastewater is delivered to the purchase applicant B, or the price of the laundry wastewater delivered to the purchase applicant B within a certain period (for example, one month) may be received at a later date. ..
Further, the washing wastewater provided to the purchase applicant B is used as, for example, agricultural water. In this way, the laundry wastewater is sold.

(Example of screen of purchase applicant terminal 400)
Information on the purchase of laundry wastewater (or information on the sale of laundry wastewater) may be displayed on the screen of the purchase applicant terminal 400. FIG. 10B is a diagram showing an example of the screen of the purchase applicant terminal 400. In the illustrated example, the screen of the purchase applicant terminal 400 of the purchase applicant B will be described.

On the screen of the purchase applicant terminal 400, the capacity of the tank of the purchase applicant B, the amount of laundry drainage accumulated in the tank of the purchase applicant B, the amount of laundry drainage that the purchase applicant B desires to purchase, and the laundry drainage The scheduled delivery date and time, the price to be paid by the purchase applicant B, and the past purchase history are displayed. The amount of laundry wastewater that the purchaser B wants to purchase, the scheduled delivery date and time of the laundry wastewater, and the price that the purchaser B plans to pay are information about the purchaser B's purchase desire.
In addition, the capacity of the tank of the purchaser B, the amount of laundry drainage accumulated in the tank of the purchaser B, and the amount of the laundry drainage that the purchaser B wants to purchase are the amount of the laundry drainage of the purchaser B. Information about quantity. Here, it can be said that the capacity of the tank of the purchase applicant B is the maximum amount of the washing wastewater purchased by the purchase applicant B. Further, the amount of wastewater collected in the tank of the purchase applicant B can be regarded as the amount of laundry wastewater purchased by the purchase applicant B in the past.

In this example, the capacity of the tank of the purchase applicant B is 5000 liters. The amount of wastewater collected in the tank is 1000 liters. The amount of wastewater to be purchased is 1000 liters, the scheduled delivery date and time is from 10:00 to 11:00 on October 2, 2019, and the price to be paid by the purchase applicant B is 300 yen. Further, as the past purchase history, the past delivery date and time, the amount of wastewater purchased, and the price paid (or the price paid) by the purchase applicant B are shown. In this example, 3000 liters were purchased on September 15, 2019, and the price paid (or the price paid) for the purchase is 900 yen.

For example, the capacity of the tank of the purchase applicant B is registered by the purchase applicant B. The amount of washing wastewater accumulated in the tank of the purchase applicant B is transmitted from the sensor provided in the tank to the management server 100, and is transmitted from the management server 100 to the purchase applicant terminal 400. Further, the amount of washing wastewater accumulated in the tank of the purchase applicant B may be transmitted from the sensor provided in the tank to the purchase applicant terminal 400, and may be transmitted from the purchase applicant terminal 400 to the management server 100. The amount of wastewater that the purchase applicant B wishes to purchase is input to the purchase applicant terminal 400 by the purchase applicant B, and is transmitted from the purchase applicant terminal 400 to the management server 100. The scheduled delivery date and time, the price to be paid by the purchase applicant B, and the past purchase history are transmitted from the management server 100 to the purchase applicant terminal 400.

In the present embodiment, the purchase applicant terminal 400 is used as an example of the information processing device of the purchase applicant. Further, as an example of the grasping means for grasping the amount of wastewater desired to be purchased by the purchase applicant, the purchase request information acquisition unit 122 is used. Further, as an example of the display means to be displayed on the information processing device of the purchase applicant, the purchase applicant notification unit 127 is used. However, these grasping means and display means may be realized by the purchase applicant terminal 400.

(Example of processing to inspect the water quality of laundry wastewater)
In the present embodiment, the water quality of the washing wastewater may be inspected before collecting the washing wastewater. In other words, the management server 100 may grasp the amount of wastewater after the water quality is inspected as the amount of wastewater collected from the provider. The water quality inspection is, for example, an inspection for impurities and nutrients contained in laundry wastewater. For example, if the water quality of the washing wastewater satisfies a predetermined condition by the inspection, the result is rejected and the washing wastewater is not collected. In this case, the vacuum car does not suck. Further, for example, if a condition different from the above-mentioned predetermined condition is set and the water quality of the washing wastewater satisfies this condition by the inspection, the result is passed and the washing wastewater may be collected.

Here, the impurity is, for example, a surfactant. Further, the impurity is, for example, a substance contained in a detergent other than the magnesium material. Furthermore, impurities are, for example, substances that are harmful to agriculture.
Further, the predetermined conditions are, for example, the conditions of impurities contained in the washing wastewater. More specifically, for example, the condition is that the mass percent concentration of impurities contained in the washing wastewater is equal to or higher than the threshold value. In addition, if the mass percent concentration of impurities contained in the washing wastewater is equal to or more than the threshold value, the product will be rejected and the washing wastewater will not be collected. On the other hand, if the mass percent concentration of impurities contained in the washing wastewater is below the threshold value, the result is passed and the washing wastewater is collected.
Further, predetermined conditions may be used as conditions for nutrients contained in the washing wastewater. More specifically, for example, the condition is that the mass percent concentration of nutrients contained in the washing wastewater is equal to or less than the threshold value. In addition, if the mass percent concentration of nutrients contained in the laundry wastewater is below the threshold value, it will be rejected and the laundry wastewater will not be collected. On the other hand, if the mass percent concentration of nutrients contained in the laundry wastewater exceeds the threshold value, the result is passed and the laundry wastewater is collected.

Further, the result of the inspection is stored in the collection information DB 114 in association with the provider identification information. For example, as a result of the inspection, pass or fail, information on impurities contained in the washing wastewater, and information on nutrients contained in the washing wastewater are stored in the recovery information DB 114. In addition, the result of the inspection may be notified to the provider. Here, in the case of failure, the provider may be notified not to wash with a detergent other than the magnesium material, for example.
The water quality inspection may be performed manually by the provider or the collection company, or may be automatically performed by the inspection tool provided in the tank of the provider. Further, the washing wastewater stored in the tank may be inspected, or the washing wastewater before being stored in the tank may be inspected.

In addition, the provider's tank has a double structure, and the water quality is inspected in the first tank, and if the inspection is passed, the washing drainage from the first tank is moved to the second tank. It may be that. In this case, the collector collects the laundry wastewater from the second tank. More specifically, for example, the washing wastewater collected in the first tank is inspected regularly (for example, every day). If the inspection is passed, the drainage pipe connecting the first tank and the second tank is opened, and the washing drainage of the first tank moves to the second tank. On the other hand, if it fails, the washing wastewater collected in the first tank is not subject to collection and is discarded.

(Example of processing to calculate the price to be paid to the provider according to the water quality of the laundry wastewater)
In the present embodiment, the payment price calculation unit 115 may calculate the price to be paid to the provider according to the water quality of the washing wastewater collected from the provider. For example, if the amount of laundry waste collected is 1000 liters and the amount is 0.1 yen per liter of laundry waste regardless of the water quality, 100 yen will be paid to the provider. Here, depending on the water quality of the laundry wastewater, the price paid to the provider may be increased or decreased from 100 yen. More specifically, for example, the higher the mass percent concentration of nutrients contained in the laundry wastewater, the higher the price paid to the provider. Also, for example, the higher the mass percent concentration of impurities contained in the laundry wastewater, the cheaper the price paid to the provider is calculated.

(Example of processing to calculate the price to be paid to the provider according to the attributes of the provider)
In addition, the payment price calculation unit 115 may calculate the price to be paid to the provider according to the attributes of the provider. For example, if the amount of laundry waste collected is 1000 liters and the amount is 0.1 yen per liter of laundry waste regardless of the water quality, 100 yen will be paid to the provider. Here, the price paid to the provider may be increased or decreased from 100 yen according to the attributes of the provider.

More specifically, for example, when the provider is a contractor, there are many relatively dirty clothes, and the amount of nutrients contained in the laundry wastewater tends to be large. Therefore, when the amount of collected laundry wastewater is 1000 liters, the price paid to the provider is calculated to be higher than the usual 100 yen. Further, for example, when the provider is an individual, the clothes tend to be relatively clean and the amount of nutrients contained in the laundry wastewater tends to be small. Therefore, when the amount of collected laundry wastewater is 1000 liters, the price paid to the provider is calculated to be cheaper than the usual 100 yen. Further, for example, the price to be paid to the provider may be calculated according to attributes such as the family structure and age of the provider. More specifically, for example, the larger the number of children, the more dirty clothes tend to be, and the greater the amount of nutrients contained in the laundry wastewater. Therefore, it is calculated that the larger the number of children, the higher the price paid to the provider.
The price to be paid to the provider may be calculated according to both the water quality of the washing wastewater and the attributes of the provider.

(Example of processing to calculate the price received from the purchase applicant according to the water quality of the washing wastewater)
Further, the receipt price calculation unit 125 may calculate the price received from the purchase applicant according to the water quality of the washing wastewater that the purchase applicant desires to purchase. For example, if the amount of washing wastewater to be purchased is 1000 liters and the amount of washing wastewater is 0.3 yen per liter of washing wastewater regardless of the water quality, the charge for washing wastewater is 300 yen. Here, depending on the water quality of the laundry drainage, the price received from the purchase applicant may be increased or decreased from 300 yen. More specifically, for example, the higher the mass percent concentration of nutrients contained in the laundry wastewater, the higher the price received from the purchase applicant. Further, for example, the higher the mass percent concentration of impurities contained in the washing wastewater, the lower the price received from the purchase applicant is calculated.

Here, the purchase applicant may specify the water quality of the laundry wastewater to be purchased. For example, the purchase applicant specifies the water quality of the washing wastewater when inputting the purchase desire information into the purchase applicant terminal 400. For example, the mass percent concentration of nutrients and the mass percent concentration of impurities are specified. Further, the water quality of the washing wastewater may be classified into a plurality of levels such as "high", "medium", and "low", and the level desired by the purchaser (for example, "high") may be specified.

(Example of processing to calculate the price received from the purchase applicant according to the attributes of the provider)
In addition, the receipt price calculation unit 125 may calculate the price received from the purchase applicant according to the attribute of the provider who provided the laundry wastewater that the purchase applicant desires to purchase. For example, if the amount of washing wastewater to be purchased is 1000 liters and the amount of washing wastewater is 0.3 yen per liter of washing wastewater regardless of the water quality, the charge for washing wastewater is 300 yen. Here, depending on the attributes of the provider, the price received from the purchase applicant may be increased or decreased from 300 yen. More specifically, for example, if the provider is a contractor, the amount of nutrients contained in the laundry wastewater tends to be large because there are relatively many dirty clothes, so the price received from the purchase applicant is the usual 300 yen. Is calculated to be higher than. Also, for example, if the provider is an individual, the clothes are relatively clean and the amount of nutrients contained in the laundry wastewater tends to be small, so the price received from the purchase applicant will be cheaper than the usual 300 yen. Is calculated to. Further, for example, the price received from the purchase applicant may be calculated according to attributes such as the family structure and age of the provider.

Here, the purchase applicant may specify the attribute of the provider of the laundry wastewater who wishes to purchase, in the same manner as specifying the water quality of the laundry wastewater. For example, a purchaser may specify the attributes of the laundry wastewater provider (for example, contractor, individual, family structure, etc.) when entering the purchase request information into the purchase request terminal 400. good.
In addition, the price received from the purchase applicant may be calculated according to both the water quality of the washing wastewater and the attributes of the provider.

(Other examples of price)
The present embodiment is not limited to the configuration in which the price is paid to the provider who provided the laundry wastewater. This price is an example of the added value given to the provider. For example, instead of adopting the point system and paying the provider, the points to be given to the provider may be calculated as added value, and the calculated points may be given to the provider. This point can be consumed, for example, when purchasing laundry products. Further, in the present embodiment, it is not necessary to add value to the provider who provided the washing wastewater.
Further, the present embodiment is not limited to the configuration in which the price is received from the purchase applicant who purchases the washing wastewater. This price is an example of the consideration received from the purchase applicant. For example, as in the case of the provider, the point system may be adopted, and instead of receiving the price from the purchase applicant, the points held by the purchase applicant may be received. Further, in the present embodiment, it is not necessary to receive compensation from a purchase applicant who purchases laundry wastewater.

(Other examples of drainage)
In the above-mentioned example, the configuration for collecting and selling the washing wastewater as the washing wastewater utilization system 1 has been described, but the wastewater to be collected and sold in the present embodiment is not limited to the washing wastewater. For example, nutrients are also contained in wastewater after bathing a magnesium material in a bathtub. Therefore, such wastewater after bathing may be subject to collection and sale. In addition, in the present embodiment, wastewater generated by using the magnesium material can be collected and sold. In other words, this embodiment can be applied to wastewater generated by utilizing a magnesium material.

Here, the provider may prepare a tank for each type of drainage, or may prepare a common tank regardless of the type of drainage. The type of drainage is a type of use in which drainage is used, for example, drainage used for washing, drainage used for bathing, and the like. When preparing tanks for each type of drainage, for example, a tank for storing laundry drainage and a tank for storing drainage after bathing are prepared. Further, when a common tank is prepared, for example, the washing drainage and the drainage after bathing are stored in the common tank.

Further, the management server 100 may manage the type of collected wastewater. For example, information on the type of drainage such as washing drainage and drainage after bathing may be stored in the collection information DB 114. More specifically, for example, by storing the provider identification information and the information on the type of wastewater in association with each other, it becomes possible to grasp, for example, what type of wastewater the provider provided. .. Further, for example, when a vacuum car patrolls and collects wastewater, by storing the identification information for identifying the vacuum car and the information on the type of wastewater in association with each other, for example, the wastewater is stored in the vacuum car. You will be able to understand what kind of wastewater you have.
The type of drainage can be determined by, for example, information being transmitted from a sensor installed in a tank for washing drainage or information being transmitted from a sensor installed in a tank for drainage after bathing. It is grasped by 100 or the provider terminal 200.

In addition, the added value given to the provider may be calculated according to the type of wastewater. For example, even if the amount of drainage is the same for the laundry drainage and the drainage after bathing, the added value given to the provider may be different.
Further, the consideration received from the purchase applicant may be calculated according to the type of wastewater. For example, even if the amount of wastewater purchased for washing wastewater and wastewater after bathing is the same, the consideration received from the purchase applicant may be different.

(Example of processing to determine the timing and recovery route of wastewater)
In the present embodiment, the management server 100 may determine the timing and the collection route for the vacuum car or the like to collect the wastewater from the provider.

For example, the management server 100 determines the timing and the collection route for collecting the wastewater based on the amount of the wastewater accumulated in the tank of the provider. More specifically, for example, a provider whose amount of wastewater collected in a tank exceeds a threshold value without collecting it from a provider whose amount of wastewater collected in a tank is less than a threshold value (for example, 100 liters). Collect from. Providers whose amount of wastewater is below the threshold will be collected after the amount of wastewater exceeds the threshold.

Here, as described above, the amount of drainage collected in the provider's tank is transmitted to the management server 100 or the provider terminal 200 from, for example, a sensor installed in the provider's tank.
Further, the management server 100 may predict the amount of wastewater accumulated in the tank of the provider from the past history. For example, for a certain period of time (for example, one week), the amount of wastewater accumulated in the donor's tank is continuously measured by a sensor. Then, based on the measurement results for a certain period of time, the amount of wastewater accumulated in the tank is predicted. Also, for example, even if a vacuum car visits for collection several times and records the amount of wastewater accumulated in the tank each time to grasp the tendency, the amount of wastewater accumulated in the tank can be predicted. good.

Further, the management server 100 may determine the timing and the collection route for collecting the wastewater based on the attributes of the provider. For example, in a coin laundry, the amount of washing drainage tends to be larger than that in a general household. Therefore, in a general household, for example, the washing wastewater is collected every week, while in a coin laundry, for example, the washing wastewater is collected every three days.
In this way, the frequency of collecting wastewater (or the timing of collecting wastewater) may be different for each provider based on the amount of wastewater collected in the tank of the provider, the attributes of the provider, and the like.

Further, for example, the management server 100 may determine the timing and the collection route for collecting the wastewater based on the type of the wastewater collected in the tank of the provider. More specifically, for example, the management server 100 determines the collection route of the washing wastewater and the collection route of the wastewater after bathing separately.
