(Second embodiment shaped state)
FIG. 7 is a schematic diagram showing the configuration of a water treatment plant and its facility update plan support system according to the second embodiment of the present invention. Omitted, here the differences are mainly described. In the following embodiments, the same description is omitted.

In other words, the present embodiment relates to an equipment update plan support device 30 ₂ for a water treatment plant 10b having two series of water treatment processes 4 ₁ and 4 ₂ .

Accordingly, in the water treatment plant 10b, the inflow flow meters 3 ₁ and 3 ₂ that measure the inflow flow rate into the water treatment processes 4 ₁ and 4 ₂ and transmit them to the database device 20, and the water treatment processes 4 ₁ and 4, respectively. ₂ is provided with water quality sensors 4s ₁ and 4s ₂ for detecting the water quality in ₂ and transmitting the water quality data to the database device 20. Further, instead of the inlet pump 2 _1, 2 ₂ of the power meter 12 _1, 12 _2, the water treatment process 4 _1, 4 ₂ water treatment processes power meter 14 _1, 14 ₂ are provided. Each water treatment process watt-hour meter 14 ₁ , 14 ₂ individually transmits the power consumption of the water treatment process 4 ₁ , 4 ₂ to the database device 20.

  On the other hand, as shown in FIG. 8, the data storage unit 20b in the database device 20 includes the first and second inflow pump operation states, the first and second series inflow flows, the first and first flows transmitted to the database device 20. Each of the two series water quality data and the first and second series water treatment process power consumption data is sequentially written together with the date and time data, and these data are accumulated.

As shown in FIG. 9, the basic power consumption basic unit storage unit 21b replaces the above-mentioned “inflow pumps 2 ₁ and 2 ₂ ” with “a water treatment process 4 ₁ , 4 _{2 of} a processing series including a plurality of devices”. The basic power consumption basic unit indicating the power consumption basic unit in a predetermined period immediately after the introduction or immediately after the maintenance is written from the power consumption basic unit calculation unit 22, and the basic power consumption basic unit is stored. .

The power consumption basic unit calculation unit 22 replaces the above-described “inflow pumps 2 ₁ and 2 ₂ ” with a power consumption basic unit for each of the “water treatment processes 4 ₁ and 4 _{2 of} a processing series including a plurality of devices”. Specifically, referring to the data storage unit 20b, the power consumption indicating the power consumption per unit flow rate based on the power consumption amount and the inflow flow rate for each of the water treatment processes 4 ₁ and 4 _2. A function for calculating the basic unit, a function for sending the obtained power consumption basic unit for each of the water treatment processes 4 ₁ and 4 ₂ to the display device 23, and a basic power consumption basic unit in the basic power consumption basic unit storage unit 21a Is sent to the display device 23.

Next, operation | movement of the equipment update plan assistance system comprised as mentioned above is demonstrated.
For each of the first and second lines, the operation / stop status of the equipment of the inflow pumps 2 ₁ and 2 ₂ and the water treatment processes 4 ₁ and 4 ₂ is measured as a digital signal, and the inflow flowing into the respective lines The flow rate is measured by the inflow flow meters 3 ₁ , 3 ₂ , and the power consumption of these devices is sensed by the watt hour meters 14 ₁ , 14 ₂ , and these data are stored in the database device 20 via signal lines.

  The basic power consumption basic unit storage unit 21b stores the basic unit immediately after operating each series. The current power consumption basic unit and the basic power consumption basic unit immediately after the operation of the processing sequence are displayed on the display device 23 via a signal line.

  It is preferable to use a moving average value, a time average value, a daily average value, or the like instead of an instantaneous value as a sensor value such as a flow rate used for basic unit calculation because it is less affected by sensor noise.

  The power consumption basic unit for each processing sequence follows the time as shown in FIG. 10 when the basic unit is viewed in a large span such as an annual span due to deterioration of equipment installed in each processing sequence, clogging of piping, and the like. It is thought that it becomes larger every time.

  In addition, if the equipment performance is different for each treatment series, there will be a difference in the basic unit, so if the equipment needs to be updated sequentially due to, for example, stricter treatment water quality regulations, the increase in the basic unit is expected. If it is the same as 10, it can be said that it is desirable to update the first sequence with a larger basic unit first.

  Therefore, by displaying the basic power consumption basic unit in FIG. 10 together with the current power consumption basic unit and the power consumption basic unit for each processing sequence, the facility manager assists in determining the update timing of the processing sequence. Can do.

  The facility manager also considers the basic unit of power consumption and the structural aspect of the equipment (deterioration of concrete), and if there are no structural problems, it is more economical to update the pond with a high basic unit of power consumption. It is thought that.

  As described above, according to the present embodiment, it is possible to obtain the same operational effects as those of the first embodiment even for a processing sequence including a plurality of devices, and further, from a processing sequence having a high power consumption rate. By updating, it is possible to expect a greater investment effect.

(Other embodiments)
Even if the energy consumption factor or the cost factor is monitored by multiplying the energy consumption factor by the energy conversion factor or the cost conversion factor and using another fuel, the amount of energy consumption or cost is taken into account. Good.

  The number of series is not limited to 2 and may be any number of 2 or more.

  The amount of electric power is not directly measured by the watt-hour meter, but an ammeter and a voltmeter (+ power factor system or reactive watt-hour meter) may be installed and the amount of power consumed may be measured by multiplication.

  As shown in Fig. 7, the power consumption is calculated by adding the power consumption of each device and adding the power consumption of each device. A thing may be used as the power consumption of the series.

The basic unit diagnosis unit 24 does not calculate and diagnose the difference, but may calculate and diagnose the ratio between the basic power consumption basic unit and the current power consumption basic unit.

The basic unit diagnosis unit 24 may be activated by an operator's operation immediately after maintenance of the device, and may diagnose the difference between the value immediately after maintenance and the basic power consumption basic unit (corresponding to claim 1 ). The monitoring of this value is for diagnosing the degree of recovery of the basic unit due to maintenance, and it is possible to diagnose whether or not the original device performance has been restored after maintenance. If the difference between basic maintenance power consumption and the basic power consumption basic unit is equal to or greater than a pre-registered diagnostic threshold, it can be said that the timing for updating the device is reached.

But it may also be one to monitor the dispersion of the original unit data between the last maintenance and the current maintenance (σ value). For example, based on the power consumption basic unit calculated by the power consumption basic unit calculation unit 22, the basic unit diagnosis unit 24 calculates the distributed data of the power consumption basic unit every predetermined period, and the calculated predetermined A function for calculating a difference between distributed data for each period and determining whether or not the difference is equal to or greater than a predetermined diagnostic value, and as a result of the determination, when the difference between the distributed data is equal to or greater than a predetermined diagnostic value, It is also possible to have a function of outputting the dispersion anomaly information to the display device 23.

In such a case, the display device 23 is instructed to perform maintenance. In addition, when the maintenance interval falls below a certain diagnosis value, the display device 23 is instructed to update the device.

(Working-shaped state of the 8)
FIG. 18: is a schematic diagram which shows the structure of the water treatment plant which concerns on the 8th Embodiment of this invention, and its equipment update plan assistance system.

The present embodiment is directed to the water treatment plant 10c that flows air into the water treatment process 4 of one series from the _two blowers 5 ₁ and 5 ₂ , and the equipment update plan support device 30 ₈ side includes the database device 20. A data storage unit 20c and a power consumption basic unit storage unit 21c are provided, and a basic performance input unit 29 and a rated operation basic unit comparison / evaluation unit 31 are added to the configuration shown in FIG.

  Here, the data storage unit 20c has the configuration shown in FIG. 14 as described above.

Power intensity storage unit 21c, as shown in FIG. 19, consumption blower 5 _1, which is sequentially calculated by the electric power consumption rate calculation unit 22, 5 ₂ per power consumption per unit of (= power consumption / aeration amount) Stored in association with date / time data by DBMS.

Basic performance input unit 29 by the operation of the operator, the blower 5 _1, 5 ₂ per consumption unit power consumption calculation unit for inputting the rated capacity indicating the air volume at the rated power and the rated operation indicating the power consumption amount during the rated operation of the 22 is input.

  Accordingly, the power consumption basic unit calculation unit 22 calculates the power consumption basic unit from the current power consumption and air volume in the data storage unit 20c, and sends them to the database device 20 and the display device 22. Based on the rated power and rated capacity input from the performance input unit 29, a function for calculating the rated operating power consumption unit indicating the rated power per rated capacity, and the rated operating power consumption unit for rated operation And a function of sending to the basic unit comparison and evaluation unit 31 and the display device 23.

  Based on the date and time data in the power consumption basic unit storage unit 21c, the rated operation basic unit comparison and evaluation unit 31 and the power consumption basic unit during rated operation received from the power consumption basic unit calculation unit 22 based on the date and time data in the power consumption basic unit storage unit 21c. A function for comparing the unit and, as a result of this comparison, when the power consumption basic unit within the predetermined period is always large or always small relative to the rated operation power consumption basic unit, guidance information indicating that the unit is large or small is displayed. And a function of outputting to the display device 23.

Next, operation | movement of the equipment update plan assistance system comprised as mentioned above is demonstrated.
The power consumption basic unit calculation unit 22 calculates the electric energy / aeration air flow from the information of the first air flow meter 15 ₁ , the second air flow meter 15 ₂ , the first air flow meter 6 ₁ , and the second air flow meter 6 _2. Is calculated and stored in the data storage unit 20c in the database device 20 sequentially. On the other hand, from the information on the rated capacity and rated power of each device input to the basic performance input unit 29, [rated power (rated power Calculate the rated operating power consumption basic unit calculated by (power consumption during operation) / rated capacity (aeration air volume during rated operation)]. These basic unit data are displayed on the display device 23 through signal lines.

  The rated operation basic unit comparison / evaluation unit 31 evaluates the rated operation power consumption basic unit and the power consumption basic unit within a predetermined period (for example, monthly unit, year unit), and the transition of the power consumption basic unit data indicates the rated operation power consumption. When it is always lower or higher than the power consumption basic unit, the fact is notified through the display device 23.

  As described above, according to the present embodiment, when the power consumption basic unit at the rated operation is compared with the power consumption basic unit at the normal operation, if both are always separated, this is indicated through the display device 23. By the configuration to be guided, it is possible to notify when there is a high possibility that the specification of the device and the actual operation are not compatible.

  For example, if the power consumption basic unit is always low compared to the rated operating power consumption basic unit, there is a high possibility that the equipment is over-spec, and it is more economical to select a smaller pump and reduce power consumption. There is a possibility that it can be obtained, and it becomes information that supports the judgment. Conversely, if the power consumption basic unit is always higher than the rated operating power consumption basic unit, the load on the equipment is high, so there is a high risk of failure and the possibility of shortening the life of the equipment. Updating to or adding a new pump is recommended.

  Supplementally, in the past, there are many cases where the cost or energy is different even for devices and facilities having the same performance. The reason is that the device / equipment is not necessarily operated at the rated value, and if the rotating device is a rotating device according to the quality and amount of water to be treated, the number of treated water may be reduced by a control valve.

  For this reason, conventionally, the analysis using offline data cannot take into account all the costs or energy required for actual facilities and equipment, and is not necessarily the facility replacement plan with the most economic advantage. For example, if there is a device that operates at 50% of the rating for most periods, it may be more economical in terms of cost and energy to introduce a device with a smaller rating than that device.

  However, in this embodiment, by comparing the power consumption basic unit during rated operation with the actual power consumption basic unit, it is possible to update to a device closer to the rated operation.

(Other embodiments)
The judgment of the guidance in the rated operation basic unit comparison / evaluation unit 31 is not always determined to be higher or lower than the rated operating power consumption basic unit, but a ratio (for example, 95%) or more of the power consumption basic unit for a predetermined period, It may be judged that the value is higher or lower than the rated operating power consumption basic unit.

By multiplying the power consumption basic unit by the power charge per unit power, the cost basic unit for each blower is calculated. This basic unit data is sequentially stored in the cost basic unit storage unit 32.

This value enables the first blower 5 _first and second blower 5 ₂ either operator by comparing with a blower 5 _1, 5 ₂ it is judged whether or not to update earlier, be reflected in the equipment update plan Can do.

  As described above, according to the present embodiment, the function information representing the transition of the cost basic unit for each predetermined period and the transition of the future cost basic unit is calculated, and the cost for the future predetermined period is calculated based on the function information. By comparing the life cycle costs of the current period and the future period, instead of comparing the current values, it is possible to make a more economical facility replacement plan for the future.

  This basic unit data is sequentially stored in the cost basic unit storage unit 32 ′ in the database device 20. In the cost basic unit prediction unit 34, the average data of the monthly average or year average level stored in the cost basic unit storage unit 32 ′ is stored in the cost basic unit change in the future period (for example, span of about 1 to 15 years). Originally, the cost unit of each future series is estimated by extrapolating by approximating with an exponential function as shown in the equation (1) as described above.

  On the other hand, an update plan input unit 36 receives a plan for when and which device / series to update. The updated device performance input unit 37 is input with basic performance such as rated power and rated capacity of the device to be updated.

  The total cost calculation unit 35 integrates the data predicted by the cost unit prediction unit 34 with the cost per 1 m3 inflow rate (yen / m3) required for a predetermined period in the future when the equipment is not updated.

D ′ ₂ = D ₂ · G ₂ / G ′ ₂

Assuming that the renewed equipment has almost no change in rated operation and the rated operation is almost unchanged, the cost basic unit [yen / (m ³ · year)] of the 2nd system when the 2nd system is renewed is expressed as (7) ).

C ′ _{2, t} = C _{2, t} −Ecp _{2, t} −Cb _{2, t} · D _{2, t} + D ′ ₂ · C′b ₂ (t = 10 to 10 + T) (7)

When the planned inflow is constant and Q during the planning period, the value calculated by equations (9)-(8) matches the value obtained by multiplying the hatched area in FIG. 28 (c) by Q, and this part is updated. It becomes the amount of cost reduction by.

  As described above, according to the present embodiment, the configuration for predicting the costs when the device is updated and the case where the device is not updated is used to compare the life cycle costs from the present to the future period instead of comparing the current values. Therefore, it is possible to make a more economical facility replacement plan in anticipation of the future.

  Although the life cycle cost for each series is calculated, the calculation method may not be the method of the embodiment. For example, the life cycle cost of each device installed in each system may be calculated individually and finally added together.

Even if the life cycle cost for each series is not calculated, the life cycle cost when each device is updated or not updated may be calculated. For example, the life cycle cost LC if you do not want to update and if you want to update the inflow pump 2 _1, 2 ₂ are calculated, the inflow pump 2 _1, 2 ₂ of the equipment cost, taking into account the construction costs, the inflow pump 2 _1, 2 ₂ It may be one that provides support for updating or not updating.

  Here, the water quality simulation unit 44 simulates the water quality after the facility update based on the data input from the update plan input unit 39. For example, the water quality simulation unit 44 is updated by the update plan input unit 39. Based on the “rated capacity of the device”, the updated water quality of the device is predicted by simulation, and the obtained water quality predicted value is output to the display device 23.

Next, operation | movement of the equipment update plan assistance system comprised as mentioned above is demonstrated.
The water quality simulation unit 40 simulates the water quality after the facility update based on the data set in the update plan input unit 39. If only the rated power of the equipment is changed, the water quality will not change significantly, but when changing the process configuration (for example, changing from the standard activated sludge method to the anaerobic-aerobic method (AO method)) or equipment When the rated capacity is changed to a smaller one, the treated water quality may change.

  In this case, it is necessary to examine whether the treated water quality can achieve the target water quality.

FIG. 35 is a schematic diagram showing a configuration of a water treatment plant and its facility update plan support system according to a seventeenth embodiment of the present invention.

  In the present embodiment, a water quality cost calculation unit 45 is added to the configuration shown in FIG.

  Here, the water quality cost calculation unit 45 calculates the water quality cost by multiplying the predicted value of the water quality obtained by the water quality simulation unit 44 by a predetermined cost conversion coefficient, and sends this water quality cost to the total cost calculation unit 35. It has a function to do.

  Accordingly, the total cost calculation unit 35 corrects the cost predicted by the above-described function based on the water quality cost received from the water quality cost calculation unit 45.

Next, operation | movement of the equipment update plan assistance system comprised as mentioned above is demonstrated.
The water quality cost calculation unit 45 converts the cost of the water quality prediction result calculated by the water quality simulation unit 44, for example, in the form of equation (10).

_{EC = w 1 · s 1 +} w 2 · s 2 + w 3 · s 3 + ··· + w n · s n (10) formula EC: water quality cost (yen)
w _1, ···, w _n: water quality s _1, ···, cost conversion factor of s _n [circle / (kg / day)]
s _1, ···, s _n: estimated load amount of evaluated water quality (kg / day)
Water s _1, · · ·, to correspond to a s _n, if the sewage treatment plant, COD (chemical oxygen demand: Chemical oxygen demand), BOD (biochemical oxygen demand: biochemical oxygen demand), SS (suspended solids), TN, TP, etc. are mentioned. Instead of converting all of these, the representative water quality may be converted into costs.

  If it is a water purification plant, there are 50 water qualities stipulated by the Waterworks Law, but it may be represented by turbidity, for example. For example, the conversion factor of W1... Wn can be estimated from the number of yen generally required to remove 1 kg of the water quality. In Europe, such as the Netherlands and Belgium, there is a levy system (a system that collects a levy for the discharge load from sewage treatment plants for nitrogen, phosphorus, and COD). There is also a method.

  The total cost calculation unit 35 performs optimization calculation so that the sum of the water quality cost EC and the operation cost is minimized.

  As described above, according to the present embodiment, in addition to the effects of the seventeenth embodiment, the configuration that optimizes the renewal plan including the water quality cost after the facility renewal takes into account not only economic aspects but also environmental aspects. It is possible to formulate an optimal equipment replacement plan.

The cumulative operation time measuring device 47 has a function of measuring the cumulative operation time of each inflow pump 2 ₁ , 2 ₂ and holding the cumulative operation time.

The facility evaluation function calculation unit 48 calculates a difference between the basic power consumption basic unit in the basic power consumption basic unit storage unit 21a and the current power consumption basic unit calculated by the power consumption basic unit calculation unit 22. The “difference”, the “insulation level” obtained by each of the insulation diagnostic devices 52 ₁ and 52 ₂ , the “cumulative operation time” obtained by the cumulative operation time measuring device 47, and the “number of activations” obtained by the counting device 46 And the number of stops ”multiplied by individual normalization factors, and the total is calculated, and when the evaluation value exceeds a predetermined threshold, maintenance of the device is performed. And a function for outputting the prompting guidance information to the display device 23.

Next, operation | movement of the equipment update plan assistance system comprised as mentioned above is demonstrated.
The power consumption basic unit calculation unit 22 calculates the power consumption basic units C ₁ and C ₂ of each inflow pump from the information of the power consumption of each inflow pump 2 ₁ and 2 ₂ and the measured value of the inflow flowmeter. In addition, the basic unit of power consumption at the beginning of equipment installation will be maintained at C ₀₁ and C ₀₂ .

In the first and second inflow pump insulation diagnostic devices 52 ₁ and 52 ₂ , the leakage current of the switch gear connected to each of the inflow pumps 2 ₁ and 2 ₂ is detected by a CT (Current Trans-former) sensor, and the panel Estimate the amount of partial discharge charge proportional to the decrease in insulation level by detecting vibration and enclosure vibration of the circuit breaker with AE (Acoustic Emission) sensor, wavelet transforming AE signal, removing noise component and analyzing Based on this partial discharge charge amount, the insulation levels (I ₁ , I ₂ ) of the inflow pumps 2 ₁ , 2 ₂ are evaluated in 10 stages (the higher the level, the lower the insulation level is judged). Here, a technique for estimating a partial discharge charge amount using a CT sensor and an AE sensor is described in detail in, for example, JP-A-2002-90413.

The pump start / stop frequency counting device 46 counts how many times each of the first and second inflow pumps 2 ₁ , 2 ₂ has been started / stopped (count values O ₁ , O _2). ).

On the other hand, the cumulative operation time measuring device 47 measures the cumulative operation time (T ₁ [hour], T ₂ [hour]) when the inflow pumps 2 ₁ and 2 _{2 are} activated.

  In the facility evaluation function calculation unit 48, for example, the following expressions (11) and (12) are calculated.

DE ₁ = Zc · (C ₁ −C ₀₁ ⁾ + Ze · I ₁ + Zo · O ₁ + Zt · T ₁ (11)
DE ₂ = Zc · (C ₂ −C ₀₂ ) + Ze · I ₂ + Zo · O ₂ + Zt · T ₂ (12)
DE ₁ : Facility diagnosis evaluation function value of inflow pump 1
DE ₂ : Facility diagnosis evaluation function value of inflow pump 2
Zc: Power consumption intensity standardization factor
Ze: insulation diagnosis value normalization factor
Zo: Start / stop frequency normalization factor
Zt: Cumulative operation time normalization coefficient Each normalization coefficient is set based on the judgment value for equipment replacement. For example, the normalization factor of the unit deterioration rate is 20% of the initial basic unit, the insulation level is 8, the start / stop count is 100 times, the cumulative operation time is 5 years, and the equipment replacement timing is
Set Zc = 1 / 1.2, Ze = 1/8, Zo = 1/100, Zt = 1 / (5 ・ 365 ・ 24).

  The evaluation function value is displayed on the display device 23, and when the evaluation function value exceeds a preset value, guidance is given to perform maintenance or update.

  As described above, according to the present embodiment, since the degree of deterioration of the device is evaluated based on the difference in the power consumption basic unit, the insulation level of the device, the cumulative operation time, and the number of start / stop operations, for example, comparison of DE1 and DE2 Therefore, it is possible to determine which inflow pump has a higher degree of deterioration of the device, and therefore it is possible to determine which pump should be replaced preferentially.

  Since not only the basic unit deterioration but also parameters related to insulation diagnosis and device usage status are included in the vote value, it is possible to support device maintenance and update timing from a comprehensive viewpoint.

(Other embodiments)

FIG. 37 is a schematic diagram showing the configuration of a water treatment plant and its equipment update plan support system according to a nineteenth embodiment of the present invention.

  The water treatment plant 10c ′ targeted by the present embodiment includes a blower 5 that supplies air into the biological reaction tank in the water treatment process 4, an anemometer 6 that measures the amount of air supplied from the blower 5, and An air diffuser 7a for refining the air supplied from the blower 5 and dissolving oxygen in the air, and a dissolved oxygen meter 8 for measuring dissolved oxygen in the biological reaction tank are installed. Further, the power consumption of the blower 5 is measured by the watt-hour meter 15.

On the other hand, the facility update plan support device 30 ₁₉ includes a basic air magnification storage unit 53 and an air magnification calculation unit 54 in the same configuration as in FIG.

  Here, as shown in FIG. 38, the basic air magnification storage unit 53 stores the air magnification calculated by the air magnification calculation unit 54 together with the date / time data.

  The air magnification calculator 54 relates to the biological reaction tank in the water treatment plant 4 and divides the air volume by the blower 5 by the inflow rate by the inflow pump 2 to calculate the air magnification of the biological reaction tank, and this air It has a function of writing the magnification together with the date / time data in the basic air magnification storage unit.

Next, operation | movement of the equipment update plan assistance system comprised as mentioned above is demonstrated.
The power consumption basic unit calculation unit 22 sequentially calculates the power consumption basic unit from the information of the first air flow meter 6 and the first blower watt hour meter 15 by calculating (power consumption / aeration air flow).

  The basic power consumption basic unit storage unit 21c stores a power consumption basic unit that is an average value for a predetermined period (about one day to one week) immediately after the blower 5 is installed.

  The current power consumption basic unit and the basic power consumption basic unit immediately after the introduction of the blower are displayed on the display device 23 via a signal line. It is desirable to use a moving average value, a time average value, a daily average value, and the like for sensor values such as the air flow meter 6 used for calculation of the basic unit, not instantaneous values, because they are less affected by sensor noise.

The air magnification calculator 54 sequentially calculates the air magnification from the information of the inflow flow meter 3 and the first air flow meter 6 by calculating (aeration air volume / inflow flow rate). The basic air magnification storage unit 53 stores an air magnification that is an average value for a predetermined period (about 1 day to about 1 week) immediately after the air diffuser 7 is installed. The current air magnification and the air magnification immediately after the introduction of the air diffuser are displayed on the display device 23 via a signal line.
The supply amount of air is often controlled so that the measured value of the dissolved oxygen meter 8 is constant or the air magnification is constant. When controlled by the dissolved oxygen meter 8, if the property (water quality) of the influent water does not change, the air magnification is almost constant. However, since the quality of sewage usually varies daily, this air magnification varies. However, if there is no abnormality such as a large inflow of rainwater, the daily average water quality will not change so much, and the air magnification will be almost the same if the average of the monthly and yearly levels is observed. Therefore, if there is no air blower abnormality, air diffuser clogging, or air leakage on the air piping, the air volume required to maintain the same dissolved oxygen concentration is the same, so the air magnification is kept the same. If there is any abnormality as described above, the air magnification increases. On the other hand, if the organism does not work due to poisoning or the like, the air magnification for maintaining the same dissolved oxygen is reduced. The abnormality of the blower 5 main body can be determined by comparing the power consumption basic unit of the blower 5 and the basic power consumption basic unit. Therefore, the air diffuser 7 is clogged and the air piping is compared by comparing the air magnification and the basic air magnification. Air leakage or inflow water abnormality is determined. The comparison may be a difference, and may be determined to be abnormal if the difference is greater than or equal to a certain threshold value, or may be determined to be abnormal if the ratio or rate of change is greater than or equal to the threshold value.

  On the other hand, when the air magnification is controlled to be constant, the average dissolved oxygen concentration decreases when there is an abnormality in the blower 5, the air diffuser 7 is clogged, or there is an air leak on the air pipe. On the other hand, when poisonous substances are mixed, the dissolved oxygen concentration greatly increases.

  Abnormality of the blower 5 main body can be determined by comparing the basic power consumption basic unit with the basic power consumption basic unit of the blower 5, and therefore, by monitoring the dissolved oxygen concentration average value, the air diffuser 7 is clogged and the air pipe Abnormalities such as air leaks or abnormalities such as poisoning can be determined.

  As described above, according to the present embodiment, it is possible to determine not only the abnormality of the main body of the blower 5 but also various kinds of abnormalities by monitoring the relationship between the power consumption basic unit of the blower 5, the air magnification, and the dissolved oxygen. it can.
