[0008] Embodiments of this disclosure will be described below with reference to the drawings. However, this description should not be interpreted as limiting, and will not limit the subject matter described in the claims. Furthermore, various changes, substitutions, and modifications can be made without departing from the spirit and scope of this disclosure. Different embodiments can also be combined as appropriate. Note that the positions and numbers of pumps, piping, and valves in the following examples are examples only and are not limited thereto.

[0009] [Water treatment system 1000 in the first embodiment] First, the configuration of the water treatment system 1000 in the first embodiment will be described. Figures 1 to 3 are diagrams illustrating the configuration of the water treatment system 1000 in the first embodiment.

[0010] The water treatment system 1000 is, for example, a sludge treatment system using the activated sludge method. Specifically, as shown in Figures 1 and 2, the water treatment system 1000 includes, for example, a primary sedimentation tank 10, a tank 20 (hereinafter also referred to as the reaction tank 20), a final sedimentation tank 30, a concentration device 40, a concentration device 50, a tank 60 (hereinafter also referred to as the digestion tank 60), and a blower 70.

[0011] The primary sedimentation tank 10 separates pollutants such as organic matter (for example, solid organic matter) contained in the water to be treated by sedimentation. After the separation of pollutants, the water to be treated is discharged from the primary sedimentation tank 10 to the reaction tank 20. Specifically, the water to be treated after the separation of pollutants is discharged from the primary sedimentation tank 10 to the reaction tank 20. Furthermore, the pollutants separated from the water to be treated are discharged from the primary sedimentation tank 10 to the concentration device 40 as primary sludge.

[0012] The reaction tank 20 has, for example, a tank body 21 from which the water to be treated is discharged from the primary sedimentation tank 10. The reaction tank 20 also has a plurality of aeration units 22 that supply air containing at least oxygen (hereinafter simply referred to as air) from the bottom of the tank body 21 to the activated sludge (aerobic microorganisms) present in the tank body 21. Each of the plurality of aeration units 22 is, for example, an aeration device. The water to be treated in the reaction tank 20 is treated, for example, by biological treatment. After the biological treatment, the water to be treated is discharged, for example, from the reaction tank 20 to the final sedimentation tank 30. The following description will assume that the reaction tank 20 is provided with a plurality of aeration units 22, but the reaction tank 20 may be provided with, for example, only one aeration unit 22.

[0013] Specifically, in the reaction tank 20, for example, the treated water flowing in from the inlet 23 (hereinafter also referred to as the inflow section 23) provided at the end on the primary sedimentation tank 10 side flows through the reaction tank 20 and flows out from the outlet 24 (hereinafter also referred to as the outflow section 24) provided at the end on the final sedimentation tank 30 side. During this period, the organic matter contained in the treated water is oxidized and decomposed by aerobic microorganisms, namely BOD (Biochemical Oxygen Demand) oxidizing bacteria, contained in the activated sludge. That is, in the reaction tank 20, for example, the removal of the organic matter contained in the treated water supplied from the primary sedimentation tank 10 is carried out. Also, in the reaction tank 20, for example, ammonia nitrogen in the treated water is nitrified to nitrite nitrogen by nitrifying bacteria, which are aerobic microorganisms in the activated sludge, and further, the nitrified nitrite nitrogen is nitrified to nitrate nitrogen. Also, in the reaction tank 20, for example, nitrogen is generated from nitrite nitrogen and nitrate nitrogen contained in the treated water by denitrifying bacteria, which are anaerobic microorganisms contained in the activated sludge.

[0014] Hereinafter, the direction in which the treated water flows in the reaction tank 20 (for example, the longitudinal direction of the reaction tank 20) is also simply referred to as the flow direction.

[0015] Also, hereinafter, the case where the air diffusers 22a, 22b, 22c, 22d, 22e, and 22f (that is, six air diffusers 22) are provided in the reaction tank 20 will be described. However, the reaction tank 20 may be provided with, for example, a number of air diffusers 22 other than six.

[0016] Also, in the above example, the case where the water treatment system 1000 has one reaction tank 20 has been described, but it is not limited to this. Specifically, the water treatment system 1000 may, for example, have a plurality of reaction tanks 20. And in this case, each of the plurality of reaction tanks 20 may, for example, treat the treated water discharged from the primary sedimentation tank 10 in parallel.

[0017] The final sedimentation tank 30 separates and discharges the activated sludge contained in the treated water discharged from the reaction tank 20, for example. Then, the final sedimentation tank 30 supplies a part of the activated sludge as excess sludge to the concentration device 50, and returns the activated sludge other than the excess sludge to the reaction tank 20 as returned sludge. Thereafter, the treated water (supernatant) after the separation of the activated sludge is discharged from the final sedimentation tank 30 to a subsequent sterilization treatment device (not shown), for example. And the treated water sterilized in the sterilization treatment device is discharged from the sterilization treatment device to a river or the like, for example.

[0018] The concentration device 40 concentrates the primary sediment sludge discharged from the first sedimentation tank 10, for example. Then, the concentrated primary sediment sludge is discharged from the concentration device 40 to the digestion tank 60, for example. The liquid separated from the primary sediment sludge by concentration is returned from the concentration device 40 to the first sedimentation tank 10, for example.

[0019] The concentration device 50 concentrates the excess sludge discharged from the final sedimentation tank 30, for example. Then, the concentrated excess sludge is discharged from the concentration device 50 to the digestion tank 60, for example. The liquid separated from the excess sludge by concentration is returned from the concentration device 50 to the final sedimentation tank 30, for example.

[0020] The digestion tank 60 anaerobically digests (decomposes) the organic substances contained in the primary sediment sludge supplied from the concentration device 40 and the excess sludge supplied from the concentration device 50 by biological reaction by anaerobic bacteria in the digestion tank 60 to generate digested sludge. Specifically, the anaerobic bacteria in the digestion tank 60 generate digestion gas (hereinafter, also simply referred to as digestion gas) such as methane gas during the digestion process, for example. And the digested sludge generated in the digestion tank 60 is supplied to subsequent equipment such as an incinerator (not shown) after being dehydrated in a dehydration device (not shown), for example.

[0021] In the above example, the water treatment system 1000 was described in the case where it has a digester tank 60, but it is not limited to this. Specifically, the water treatment system 1000 may, for example, not have a digester tank 60. In this case, the primary sludge supplied from the thickening device 40 and the excess sludge supplied from the thickening device 50 may, for example, be supplied directly to the dewatering device.

[0022] The blower 70 is, for example, a blower that supplies air to the reaction vessel 20. Specifically, the blower 70 supplies air into the reaction vessel 20, for example, through a plurality of aeration units 22 provided in the reaction vessel 20.

[0023] In the example shown in Figure 2, the reaction tank 20 is equipped with six aeration sections 22 (aeration section 22a, aeration section 22b, aeration section 22c, aeration section 22d, aeration section 22e, and aeration section 22f) along the flow direction. In the example shown in Figure 2, air from the blower 70 is supplied to aeration section 22a via pipes L1, L2, and La; air from the blower 70 is supplied to aeration section 22b via pipes L1, L2, and Lb; and air from the blower 70 is supplied to aeration section 22c via pipes L1, L2, and Lc. Furthermore, in the example shown in Figure 2, air from the blower 70 is supplied to the aeration section 22d via pipes L1, L3, and Ld, air from the blower 70 is supplied to the aeration section 22e via pipes L1, L3, and Le, and air from the blower 70 is supplied to the aeration section 22f via pipes L1, L3, and Lf. The following description will focus on the case where multiple aeration sections 22 are arranged in a straight line along the flow direction in the reaction tank 20, but is not limited to this. Specifically, in the reaction tank 20, for example, the aeration sections may be installed so as to spread out in a planar manner at the bottom of the reaction tank 20. Furthermore, the following description will focus on the case where the water treatment system 1000 has one blower 70 (where there is one blower 70 supplying air to the reaction tank 20), but is not limited to this. Specifically, the water treatment system 1000 may, for example, have multiple blowers 70 (multiple blowers 70 supplying air to the reaction tank 20).

[0024] Furthermore, as shown in Figure 3, the water treatment system 1000 further includes, for example, a control device 100 and an information processing device 200. The following description will focus on the case where the control device 100 and the information processing device 100 are separate devices; however, the control device 100 and the information processing device 100 may, for example, be a single device.

[0025] The control device 100, for example, controls the supply of the required amount of air from the blower 70 to the reaction vessel 20 (hereinafter also referred to as air supply control).

[0026] Specifically, the control device 100 controls the amount of air supplied to the reaction vessel 20 (the amount of air supplied to each region within the reaction vessel 20) by, for example, controlling the amount of air supplied from the blower 70, as well as controlling the opening and closing of valve V1 in piping L2, valve V2 in piping L3, valve Va in piping La, valve Vb in piping Lb, valve Vc in piping Lc, valve Vd in piping Ld, valve Ve in piping Le, and valve Vf in piping Lf. Hereinafter, valves Va, Vb, Vc, Vd, Ve, and Vf will be collectively referred to simply as valve V.

[0027] More specifically, the control device 100 acquires information indicating the water quality of the water to be treated in the reaction tank 20 (the load of the water to be treated flowing into the reaction tank 20 from the primary sedimentation tank 10) (hereinafter also referred to as water quality information), and calculates the amount of air that needs to be supplied to the reaction tank 20 (hereinafter also referred to as the required amount) according to the acquired water quality information. In other words, the control device 100 calculates the required amount of air that can keep the water quality of the water to be treated in the reaction tank 20 within a predetermined allowable range. The control device 100 then calculates the discharge pressure (discharge pressure in the blower 70) that can supply the required amount of air or an amount exceeding the required amount to the reaction tank 20. Subsequently, the control device 100 adjusts the amount of air supplied to the reaction tank 20 by setting the calculated discharge pressure in the blower 70 and controlling the opening and closing of each valve V.

[0028] In other words, the control device 100 performs control (hereinafter also referred to as variable pressure control) to adjust (change) the discharge pressure of the blower 70 based on the acquired water quality information.

[0029] This makes it possible to prevent, for example, the supply of an excessive amount of air from the blower 70 in the water treatment system 1000. As a result, it becomes possible to improve the operating efficiency of the blower 70 in the water treatment system 1000, and to reduce the power consumption of the blower 70.

[0030] In this case, the control device 100 may, for example, identify the required amount of air corresponding to the acquired water quality information (the required amount of air for the reaction tank 20) ​​by referring to a storage unit (not shown) that stores correspondence information relating the water quality of the water to be treated in the reaction tank 20 to the required amount of air for the reaction tank 20. Alternatively, the control device 100 may identify the discharge pressure corresponding to the acquired water quality information (the discharge pressure at the blower 70) by referring to another storage unit (not shown) that stores other correspondence information relating the water quality of the water to be treated in the reaction tank 20 to the discharge pressure at the blower 70.

[0031] Furthermore, the water quality information may be, for example, a concentration measured by an ammonia concentration meter (not shown) installed in the reaction tank 20, indicating the concentration of at least one of ammonia and ammonium nitrogen in the water to be treated in the reaction tank 20. Alternatively, the water quality information may be, for example, a concentration measured by a nitrate concentration meter (not shown) installed in the reaction tank 20, indicating the concentration of at least one of nitrate, nitrite, nitrate nitrogen, and nitrite nitrogen in the water to be treated in the reaction tank 20. Furthermore, the water quality information may be, for example, a concentration measured by a DO (Dissolved Oxygen) concentration meter (not shown) installed in the reaction tank 20, indicating the DO concentration in the water to be treated in the reaction tank 20.

[0032] Returning to Figure 3, the information processing device 200 performs a process (hereinafter also called information output processing) to output information used in the design (manufacturing) of a blower 70 that can efficiently supply air to the reaction vessel 20 (hereinafter also called reference information or second information) at a time before the design (manufacturing) of the blower 70 is carried out.

[0033] Specifically, the information processing device 200 calculates the frequency of each of several types of operating states (hereinafter simply referred to as several types) by referring to a storage unit that stores information indicating the operating state of a predetermined blower at multiple timings (hereinafter also referred to as operating information or first information). The operating state may be, for example, at least one of the airflow rate and discharge pressure of the predetermined blower. The predetermined blower may be, for example, another blower (hereinafter simply referred to as another blower) that supplies (or has supplied) air to the same equipment (i.e., reaction tank 20) ​​as the equipment to which blower 70 supplies air. In this case, the operating information may be, for example, actual information about the operating state of the other blower at past timings. The predetermined blower may also be, for example, blower 70 itself. In this case, the operating information may be, for example, predictive information about the operating state of blower 70 at future timings. Furthermore, each of the multiple categories may represent, for example, values ​​or ranges corresponding to operating conditions (e.g., values ​​or ranges of airflow rate or discharge pressure). Note that the values ​​or ranges corresponding to each of the multiple categories are different from the values ​​or ranges corresponding to other categories.

[0034] The information processing device 200 then identifies, for example, one of several types whose calculated frequency satisfies a condition (hereinafter also referred to as the first condition) (hereinafter also referred to as a specific type). More specifically, the information processing device 200 identifies, for example, the type with the highest calculated frequency among several types as a specific type.

[0035] Subsequently, the information processing device 200 outputs, for example, reference information indicating the specific type identified. More specifically, the information processing device 200 outputs the reference information to an operating terminal (not shown) that can be viewed by, for example, a worker (hereinafter simply referred to as "worker") who manufactures the blower 70.

[0036] In other words, blowers are sometimes designed (manufactured) to have the highest operating efficiency (blower efficiency) when the airflow rate or discharge pressure is at its maximum. Therefore, depending on the amount of air required in the reaction vessel 20, the supply of air from the blower to the reaction vessel 20 may not be efficient.

[0037] Therefore, the information processing device 200 in this embodiment identifies the type of operating state (airflow rate and discharge pressure) that is frequently set in the blower 70 based on operating information corresponding to a predetermined blower, at a time before the design (manufacturing) of the blower 70 is carried out, and outputs reference information indicating the identified type. Specifically, the information processing device 200 in this embodiment predicts the type of operating state that is frequently set in the blower 70 based on actual operating information corresponding to other blowers and predicted operating information corresponding to the blower 70, and outputs reference information indicating the predicted type. Then, the worker, for example, refers to the reference information output by the information processing device 200 and designs (manufactures) the blower 70 such that the operating efficiency at the airflow rate corresponding to the type indicated by the reference information is higher than the operating efficiency at other airflow rates.

[0038] As a result, in the water treatment system 1000 of this embodiment, by using a blower 70 designed (manufactured) based on reference information, for example, the power consumption required for supplying air to the reaction tank 20 (power consumption of the blower supplying air to the reaction tank 20) ​​can be suppressed, and the supply of air to the reaction tank 20 can be made more efficient. Specifically, in the water treatment system 1000 of this embodiment, by using a blower 70 designed (manufactured) based on reference information in addition to performing variable pressure control, for example, the power consumption required for supplying air to the reaction tank 20 can be further suppressed, and the supply of air to the reaction tank 20 can be made more efficient.

[0039] In this embodiment, the water treatment system 1000 may, for example, use a blower 70 designed (manufactured) based on reference information instead of performing variable pressure control, thereby suppressing the power consumption required to supply air to the reaction vessel 20.

[0040] [Control device 100 in the first embodiment] Next, the configuration of the control device 100 in the first embodiment will be described. Figure 4 is a diagram illustrating the hardware configuration of the control device 100.

[0041] As shown in Figure 4, the control device 100 is a computer device having, for example, a CPU 101 which is a processor, memory 102, a communication device 103, and a storage medium 104. Each part is connected to the others, for example, via a bus 105.

[0042] The storage medium 104 has, for example, a program storage area (not shown) for storing a program 110 for controlling the air supply. The storage medium 104 also has, for example, a storage unit 130 (hereinafter also referred to as the information storage area 130) for storing information used when controlling the air supply. The storage medium 104 may be, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive).

[0043] The CPU 101 controls the air supply by, for example, executing a program loaded from the storage medium 104 into the memory 102.

[0044] The communication device 103 accesses, for example, an operating terminal (not shown) used by an operator to input necessary information via a network (not shown), such as the Internet.

[0045] The control device 100 may, for example, have an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). Alternatively, the control device 100 may have, for example, a PIC (Peripheral Interface Controller). Furthermore, the air supply control may be performed, for example, by an FPGA or ASIC.

[0046] Furthermore, the following description will focus on the case where air supply control is performed by the control device 100, but air supply control may also be performed in a distributed manner across multiple control devices, for example.

[0047] [Information processing device 200 in the first embodiment] Next, the configuration of the information processing device 200 in the first embodiment will be described.

[0048] As shown in Figure 5, the information processing device 200 is a computer device having, for example, a CPU 201 which is a processor, memory 202, a communication device 203, and a storage medium 204. Each part is connected to the others, for example, via a bus 205.

[0049] The storage medium 204 has, for example, a program storage area (not shown) for storing a program 210 for performing information output processing. The storage medium 204 also has, for example, a storage unit 230 (hereinafter also referred to as the information storage area 230) for storing information used when performing information output processing. The storage medium 204 may be, for example, an HDD or an SSD.

[0050] The CPU 201 performs information output processing, for example, by executing a program loaded from the storage medium 204 into memory 202.

[0051] The communication device 203 accesses, for example, an operating terminal (not shown) where an operator inputs necessary information via a network (not shown), such as the Internet.

[0052] The information processing device 200 may, for example, have an FPGA or an ASIC. Furthermore, the information processing device 200 may, for example, have a PIC. The information output processing may be performed, for example, on an FPGA or an ASIC.

[0053] Furthermore, the following explanation will describe the case where information output processing is performed in the information processing device 200, but information output processing may also be performed in a distributed manner across multiple information processing devices, for example.

[0054] [Information output processing in the first embodiment] Next, the information output processing in the first embodiment will be described. Figure 6 is a flowchart illustrating the information output processing in the first embodiment. Figures 7 to 10 are diagrams illustrating the information output processing in the first embodiment. The following description will focus on the case where the information output processing is performed by the information processing device 1, but the information output processing may also be performed manually by an operator. Furthermore, the following description will focus on the case where the predetermined blower is another blower, and the operation information DT1 is actual operation information from past timings of the other blower.

[0055] As shown in Figure 6, the information processing device 200 refers to an information storage area 130 that stores, for example, operation information DT1 indicating the operating status of multiple timings in other blowers, and generates frequency information DT2 indicating the frequency of each of multiple types of operating status (step S1 in Figure 6). Specific examples of operation information DT1 and frequency information DT2 will be described below.

[0056] [Specific example of driving information DT1] First, we will explain a specific example of the driving information DT1. Figure 7 is a diagram illustrating a specific example of the driving information DT1.

[0057] The operation information DT1 shown in Figure 7 has the following items: "Time Period" where each time period is set, "Airflow Rate" where the airflow rate set for other blowers in each time period is set, and "Discharge Pressure" where the discharge pressure set for other blowers in each time period is set. For "Airflow Rate," for example, the ratio of each airflow rate to the maximum value of the blower that can be set for other blowers is set. Similarly, for "Discharge Pressure," for example, the ratio of each discharge pressure to the maximum value of the discharge pressure that can be set for other blowers is set. The following explanation will focus on the case where other blowers are blowers that can have their airflow rate set in 5% increments.

[0058] Specifically, in the first line of the operation information DT1 shown in Figure 7, for example, "Time zone" is set to "10 / 01 12:00:00-12:01:00", "Airflow rate" is set to "80(%)", and "Discharge pressure" is set to "70(%)".

[0059] In other words, the information in the first line of the operation information DT1 shown in Figure 7 indicates, for example, that the airflow rate and discharge pressure set for other blowers during the time period from 12:00:00 to 12:01:00 on October 1st were 80% and 70%, respectively.

[0060] Furthermore, in the second line of the operation information DT1 shown in Figure 7, for example, "Time zone" is set to "10 / 01 12:01:00-12:02:00", "Airflow rate" is set to "85(%)", and "Discharge pressure" is set to "75(%)".

[0061] In other words, the information in the second line of the operation information DT1 shown in Figure 7 indicates, for example, that the airflow rate and discharge pressure set for other blowers during the time period from 12:01:00 to 12:02:00 on October 1st were 85% and 75%, respectively. Explanation of the other information included in Figure 7 is omitted.

[0062] [Specific examples of frequency information DT2] Next, we will explain specific examples of frequency information DT2. Figure 8 is a diagram illustrating specific examples of frequency information DT2. Hereafter, we will explain assuming that each of the multiple categories includes categories corresponding to 40(%) airflow rate, 45(%) airflow rate, 50(%) airflow rate, 55(%) airflow rate, 60(%) airflow rate, 65(%) airflow rate, 70(%) airflow rate, 75(%) airflow rate, 80(%) airflow rate, 85(%) airflow rate, 90(%) airflow rate, 95(%) airflow rate, and 100(%) airflow rate. The following explanation will describe the case where frequency information DT2 for airflow rate is generated. However, the information processing device 200 may, for example, generate frequency information DT2 for discharge pressure in place of, or together with, the frequency information DT2 for airflow rate.

[0063] The frequency information DT2 shown in Figure 8 has items such as "Airflow Amount," which sets the airflow amounts that were set on other blowers, and "Frequency," which sets the frequency at which each airflow amount was set on other blowers. For example, "Frequency" may be set as the ratio of each time period at which each airflow amount was set on other blowers to the total time.

[0064] Specifically, in the first row of the frequency information DT2 shown in Figure 8, for example, "40 (%)" is set as "Airflow Rate" and "1 (%)" is set as "Frequency".

[0065] In other words, the information in the first row of the frequency information DT2 shown in Figure 8 indicates, for example, that the percentage of time when the airflow rate was set to 40% in other blowers was 1%.

[0066] Furthermore, in the frequency information DT2 shown in Figure 8, the information in the 8th row includes, for example, "75 (%)" as the "airflow rate" and "18 (%)" as the "frequency".

[0067] In other words, the information in the 8th row of the frequency information DT2 shown in Figure 8 indicates, for example, that the percentage of time when the airflow rate was set to 75% in other blowers was 18%. Explanation of the other information included in Figure 8 is omitted.

[0068] Returning to Figure 6, the information processing device 200 identifies, for example, among multiple types, the type whose frequency information DT2 calculated in step S1 satisfies the first condition as a specific type (step S2 in Figure 6).

[0069] Specifically, the information processing device 200 identifies, for example, one of several types, as a specific type, which has the highest frequency indicated by the frequency information DT2 calculated in step S1.

[0070] More specifically, for example, the maximum value among the values ​​set for "Frequency" in the frequency information DT2 shown in Figure 8 is "18(%)" set for "Frequency" in the information (information on the 8th line) where "Airflow Rate" is set to "75(%)". Therefore, in this case, the information processing device 200 identifies the type corresponding to the airflow rate of 75(%) as a specific type.

[0071] The information processing device 200 may, for example, identify as a specific type any of the types among several types whose frequency indicated by the frequency information DT2 calculated in step S1 is equal to or greater than a threshold. Specifically, the information processing device 200 may, for example, identify as a specific type the type corresponding to the largest airflow rate among the types whose frequency indicated by the frequency information DT2 calculated in step S1 is equal to or greater than a threshold.

[0072] Furthermore, the information processing device 200 may, for example, identify a predetermined number of types (hereinafter also simply referred to as a predetermined number of types) from among a plurality of types in descending order of frequency indicated by the frequency information DT2 calculated in step S1, and then identify one of the identified predetermined number of types as a specific type. Specifically, the information processing device 200 may, for example, identify the type corresponding to the largest airflow rate among the predetermined number of types as a specific type.

[0073] Then, the information processing device 200 outputs, for example, reference information DT3 indicating the specific type that has been identified (step S3 in Figure 6).

[0074] Specifically, the information processing device 200 outputs reference information DT3 to an operating terminal that can be viewed by, for example, an operator manufacturing the blower 70. A specific example of the reference information DT3 will be described below.

[0075] [Specific example of reference information DT3] Figure 9 illustrates a specific example of the reference information DT3. The following explanation will focus on the case where reference information DT3 for airflow rate is generated and output. However, the information processing device 200 may, for example, generate and output reference information DT3 for discharge pressure in place of, or together with, the reference information DT3 for airflow rate.

[0076] The reference information DT3 shown in Figure 9 has the same items as the frequency information DT2 explained in Figure 8, for example.

[0077] Specifically, in the reference information DT3 shown in Figure 9, for example, "Airflow rate" is set to "75 (%)" and "Frequency" is set to "18 (%)".

[0078] In other words, for example, the largest value among the values ​​set for "frequency" in the frequency information DT2 explained in Figure 8 is "18(%)" set for "frequency" in the information (information on the 8th line) where "airflow rate" is set to "75(%)". Therefore, in this case, the information processing device 200 identifies and outputs the information on the 8th line of the frequency information DT2 explained in Figure 8 as reference information DT3.

[0079] In step S3, the information processing device 200 may output, for example, information indicating a blower whose operating efficiency at the airflow rate indicated by the reference information DT3 satisfies the condition (hereinafter also referred to as the second condition) as reference information DT3.

[0080] Specifically, the information processing device 200 may output, for example, information indicating a blower that maximizes the operating efficiency at the airflow rate indicated by the reference information DT3, or information indicating a blower whose operating efficiency at the airflow rate indicated by the reference information DT3 is equal to or greater than a predetermined percentage of the maximum operating efficiency, as reference information DT3.

[0081] In other words, the information processing device 200 may, for example, identify (select) a blower from among a plurality of blowers whose operating efficiency at each airflow rate is known in advance, the blower whose operating efficiency at the airflow rate indicated by the reference information DT3 satisfies the conditions, and output information indicating the identified blower as reference information DT3.

[0082] Furthermore, the information processing device 200 may output, for example, information as reference information DT3 indicating the height and mounting angle of the blades of an impeller (an impeller used in a blower) that satisfies the operating efficiency conditions at the airflow rate indicated by reference information DT3.

[0083] Specifically, the information processing device 200 may output, for example, information indicating the height and mounting angle of the impeller blades that maximizes the operating efficiency at the airflow rate indicated by the reference information DT3 as reference information DT3.

[0084] Thus, the information processing device 200 in this embodiment, for example, refers to an information storage area 130 that stores operation information DT1 indicating the operating state of each of multiple timings in a predetermined blower, and generates frequency information DT2 for each of multiple types of operating states. Then, the information processing device 200 in this embodiment identifies a specific type among the multiple types in which the frequency information DT2 (the frequency indicated by the frequency information DT2) satisfies the first condition. Subsequently, the information processing device 200 in this embodiment outputs reference information DT3 indicating the identified specific type.

[0085] Specifically, in the information processing device 200 of this embodiment, the operating state is at least one of the airflow rate and discharge pressure of a predetermined blower.

[0086] Furthermore, the information processing device 200 in this embodiment identifies, for example, the type in which the calculated frequency information DT2 is the highest among a plurality of types as a specific type.

[0087] Furthermore, the information processing device 200 in this embodiment outputs, for example, information indicating a blower whose operating efficiency in an operating state corresponding to a specific type that has been identified satisfies the second condition as reference information DT3.

[0088] In other words, the information processing device 200 in this embodiment identifies the type of fan with the highest frequency (set frequency) in the fan 70 based on the operation information DT1 corresponding to a predetermined fan, and outputs reference information DT3 indicating the identified type.

[0089] Specifically, as shown in the lower graph of Figure 10, the information processing device 200 outputs information as reference information DT3 indicating that the airflow rate at which the predetermined blower was set to 75% is at its maximum frequency (maximum value), for example, when the frequency of setting the airflow rate to 75% in a predetermined blower is at its maximum.

[0090] Then, the worker designs (manufactures) the blower 70 such that the operating efficiency is maximized at the airflow rate corresponding to the type indicated by the reference information DT3 output by the information processing device 200.

[0091] Specifically, for example, if the airflow rate indicated by reference information DT3 is 75%, the worker designs (manufactures) the blower 70 (impeller of blower 70) so as to maximize the operating efficiency when the airflow rate is 75%, as shown in the upper graph of Figure 10.

[0092] As a result, in the water treatment system 1000 of this embodiment, by using a blower 70 designed (manufactured) based on reference information DT3, for example, it becomes possible to suppress the power consumption required for supplying air to the reaction tank 20, and to supply air to the reaction tank 20 efficiently. In other words, in the water treatment system 1000 of this embodiment, by using a blower 70 designed (manufactured) based on reference information DT3 that reflects the nature of the inflow load in the reaction tank 20 (for example, the magnitude of the inflow load), for example, it becomes possible to suppress the power consumption required for supplying air to the reaction tank 20, and to supply air to the reaction tank 20 efficiently. Specifically, in the water treatment system 1000 of this embodiment, by using a blower 70 designed (manufactured) based on reference information DT3 in addition to performing variable pressure control, for example, it becomes possible to further suppress the power consumption required for supplying air to the reaction tank 20, and to supply air to the reaction tank 20 more efficiently.

[0093] Furthermore, the information processing device 200 may, for example, if there are multiple maximum values ​​for the setting frequency of the airflow rate in the lower graph of Figure 10, identify the maximum value corresponding to the largest airflow rate and output information indicating the airflow rate corresponding to the identified maximum value as reference information DT3.

[0094] Furthermore, the above example described a case where the other blower is capable of setting the airflow rate in 5% increments, but this is not the only case. Specifically, the other blower may be, for example, a blower capable of setting the airflow rate in finer units. And each of the multiple types may correspond to an airflow rate range such as 40% or more and less than 45%. [Explanation of Symbols]
