Description

  The present invention relates to an operation evaluation system for evaluating operation contents of a water treatment facility or the like.

As an operation evaluation system that evaluates the operation details of water treatment facilities, etc., conventionally, plant data at water purification plants, sewage treatment plants, water departments of local governments, or sewage treatment plants of local governments are manually input to the operation index calculation device. Thus, there has been proposed a business improvement system that calculates and displays business index calculation values for water supply or sewerage (see Patent Document 1).
JP 2006-024202 A

  By the way, in water treatment facilities operated by the public such as water purification plants and sewage treatment plants, private consignment of operation management, in which operation is outsourced to the private sector, is in progress for the purpose of reducing facility operation costs. As shown in FIG. 17, the consignment form of operation management (operation manager) 101 receives facility utility costs (facility power costs, chemical costs, sludge / waste disposal costs) from the consignor 102. Entrusting in the form of a comprehensive entrustment that manages facilities is included in the entrustment costs.

  The contractor (operation manager) 101 entrusted with the operation management has its own profit to reduce the utility cost, so an incentive to improve the efficiency of the operation management to reduce the utility cost works. On the other hand, regarding the water quality improvement that the treatment facility is originally required, it is only necessary to comply with the treated water quality of the contract standard, and it is difficult to provide incentives for water quality improvement.

  In addition, although utility costs and treated water quality are unclear, there is a trade-off relationship, so the operation method of reducing utility costs as much as possible and observing the contracted treated water quality standards is the most profitable for contractors. It becomes a means to enjoy. For this reason, compared with the conventional operation management, the quality of the treated water may be deteriorated, and the water environment of the treatment destination may be deteriorated.

  For these reasons, the following problems have been pointed out in the outsourcing of operation management of water treatment facilities.

(3) Since there is no means to comprehensively evaluate conventional operation and current operation in terms of water quality and cost, the contractor (operation manager) 101 is able to comply with the commissioned water quality standards and how much the cost. Because the operation content is evaluated only in terms of whether or not it has been reduced, there is a possibility that operation will be performed while keeping the minimum water quality standards and reducing the utility cost of the facility.

(4) There is PI (Performance Indicator) as an index for evaluating operation management work, and the present inventors have proposed a device that automatically calculates this from process data and extracts operation improvement points. It mainly provides information for managers, and it is left to the discretion of the driving manager to decide whether or not to improve driving.

<< Third Embodiment >> [Corresponding to Claim 3]
<Configuration>
FIG. 3 is a block diagram showing a third embodiment of the driving evaluation system according to the present invention. In this figure, parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

<< Fourth Embodiment >> [Corresponding to Claims 4 and 5]
<Configuration>
FIG. 4 is a block diagram showing a fourth embodiment of the driving evaluation system according to the present invention. In this figure, parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

  The operation evaluation system 1d shown in this figure is different from the operation evaluation system 1a shown in FIG. 1 in that an evaluation point calculation device 8 for calculating an operation evaluation point from the process data collected by the monitoring device 4a is added.

<Action>
Based on the process data collected by the monitoring device 4a, the driving evaluation point calculation device 8 calculates driving evaluation points. At this time, the higher the quality of the treated water and the lower the operation cost, the higher the evaluation point is given, and the result is displayed on the display device 5a and the monitoring device 4a, and is grasped by the operation evaluator 7 and the operation manager 6.

  For example, in a sewage treatment plant, removal of SS (floating solids), COD (chemical oxygen demand), TN (total nitrogen), and TP (total phosphorus) is required as the quality of treated water. Process data is being sensed.

  Further, as operating cost factors, there are equipment power costs such as various pumps and blowers, various chemical costs such as PAC (polyaluminum chloride) and sodium hypochlorite, and sludge disposal costs of generated sludge.

  Further, as energy consumption factors, there are consumption accompanying power consumption and other energy consumption due to use of heavy oil and the like.

  For these reasons, the operation evaluation point of the sewage treatment facility is calculated by, for example, equations (1) to (3). These are calculated hourly according to the process data from the sewage treatment plant 3 if the coefficients “a”, “b”, “c”, “w1” to “w4”, “p1” to “p3” are determined. . The calculation cycle may be a minute unit, an hour unit, or a day unit.

OP (t) = a · Eq (t) + b · OC (t) (1) where OP (t): operation evaluation point at time t Eq (t): discharge water quality evaluation point at time t OC ( t): Operating cost evaluation point at time t a, b: Weighting coefficient Eq (t) = W1 · (SSst−SS (t))
+ W2 · (CODst-COD (t))
+ W3 · (TNst−TN (t))
+ W4 · (TPst−TP (t)) (2) Equation Eq (t): Effluent water quality evaluation point at time t SSst: Effluent water quality reference value (target value) of SS (mg / L)
CODst: COD discharge water quality standard value (target value) (mg / L)
TNst: TN discharge water quality standard value (target value) (mg / L)
TPst: TP discharge water quality standard value (target value) (mg / L)
SS (t): SS sensor value at time t (mg / L)
COD (t): COD sensor value at time t (mg / L)
TN (t): Sensor value of TN at time t (mg / L)
TP (t): TP sensor value at time t (mg / L)
W1 to W4: Weighting coefficient OC (t) = (p1 · PW (t)
Ten p2 · MW (t)
10 p3 · WS (t)) / Q (3) where PW: power consumption (kwh) ⇒ watt-hour meter data, or measured values and device performance of each pump and pro-flow meter.

        MW: Amount of chemical used (kg) ⇒ Calculated from the measured value of chemical supply flow meter and chemical concentration. WS: Sludge generation amount (kg) ⇒ Calculated from the measured value of the sludge extraction flow meter and the measured value of the sludge concentration meter.

Q: Treatment plant inflow (m3 / day)
p1 to p3: Basic unit of use The parameters “W1” to “W4” used in the equations (1) to (3) are determined depending on the magnitude of the influence on the water environment at the discharge destination of the treatment facility. “P1” to “p3” are a power charge of “1 kwh”, a chemical use charge per “1 kg”, and a processing cost per “1 kg” sludge generation amount, respectively. “A” and “b” are impact factors of the water environment and cost. In Europe (Netherlands, Germany, etc.), a levy is collected for the amount of discharged water quality, and this is set based on the impact on the water environment of the treatment facility. Just do it. Dividing by the flow rate “Q” means that when the flow rate is high, the power cost of the pump and proe will naturally increase. Therefore, in order to make a fair operation evaluation, the operation evaluation point is calculated with the operation cost per unit flow rate. To do.

<Effect>
(1) Since the operation of the treatment plant can be evaluated with one index, the operation evaluator can easily determine whether the operation status of the plant is good.

(2) Since the evaluation is based on the operation cost per unit flow rate, a fair operation evaluation is possible even when the flow rate changes with respect to the operation cost.

<Modification>
In the fourth embodiment, the driving evaluation point calculation device 8 is arranged separately from the monitoring device 4a. However, a driving evaluation point calculation function may be incorporated as one function of the monitoring device 4a. Thereby, since one new apparatus is reduced, the cost of the apparatus main body can be reduced.

  Moreover, in 4th Embodiment, although the sewage treatment plant was made into object, an operation evaluation score may be similarly calculated from a treated water quality and operation cost also in a water purification plant.

  Moreover, in 4th Embodiment, the calculation formula of an evaluation score does not need to be restricted to (1)-(3) Formula. For example, it may be calculated by a function in which the score rapidly decreases when the discharged water quality exceeds a certain value.

Moreover, although the evaluation score was calculated from the operating cost and the discharged water quality in the equations (1) to (3), it may be calculated from the energy consumption and the discharged water quality, for example. Further, the parameter determination method may not be a cost-based determination method as in the embodiment, but may be determined based on the influence of energy consumption on the environment (CO ₂ emissions, air pollution due to SO ₂ emissions) or the like. .

<< Fifth Embodiment >> [Corresponding to Claim 6]
<Configuration>
FIG. 5 is a block diagram showing an embodiment corresponding to claim 6 in the driving evaluation system according to the present invention. In this figure, parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

  The driving evaluation system 1e shown in this figure is different from the driving evaluation system 1a shown in FIG. 1 in that a monitoring device 4e having a PI calculating function for calculating PI (Performance Indicator) which is a work index and an evaluation point calculating function is provided. It is provided.

<Action>
Then, the process data collected in the water treatment plant 3 is transmitted to the monitoring device 4e, and PI is calculated from the process data by the PI calculation function. For example, in the sewerage operation index “PI”, those shown in Tables 9 to 11 shown in FIGS. 6 to 8 are proposed (“Guidelines for improving sewerage maintenance service” (2003), published by the Sewerage Association) ). As can be seen from these Tables 9 to 11, the business index “PI” can be calculated from online process data (for example, “8” to “12” advanced water treatment indexes). And there are things that cannot be calculated from the process data (for example, “65th” to “67” earthquake resistance rate, etc.).

  The conventional operation evaluation system also has a calculation function for calculating a business index “PI” (for example, “8” to “12”) that can be calculated from process data. Therefore, by using this calculation function, the “PI” value of the business index “PI” that can be calculated from the online process data is calculated. Further, by multiplying the “PI” value by a weighting coefficient using the evaluation point calculation function, the driving evaluation score is calculated and displayed on the monitoring device 4e and the display device 5a together with each “PI” value. .

PIP (t): Operational evaluation point of business index PI at time t PIi (t): PI value of business index item i at time t ni: Evaluation point conversion coefficient of business index item i f (Pli (t)): Time Operation evaluation point calculation function of the work index item i at t:
At this time, the evaluation point conversion coefficient “ni” is determined by normalization based on the average value of the “PI” values of the respective business index items. In addition, depending on the item, there are “PI” values that the higher the “PI” value, the better the operation, and the lower the “PI” value, the better the operation. The better the operation, the more the equation (4) Since the score of “f (PIi (t))” increases, for items whose operation is better as the “PI” value is higher, “f (PIi (t))” as shown in the following equation: Define
f (PIi (t)) = ki · PIi (t) (5) For items whose operation is better as the “PI” value is lower, “f (PIi (t) )) ”Is defined.

f (PIi (t)) = ki · (Li−PIi (t)) (6) where ki, Li: evaluation point calculation coefficient <effect>
(1) The operation of the processing plant can be comprehensively evaluated by the evaluation based on the business index. Moreover, since it can evaluate with one parameter | index called an operating point, an operation evaluator can judge easily whether the operating condition of the plant is favorable.

<Modification>
Moreover, in 5th Embodiment, although it is made to use (4)-(6) Formula as a calculation formula of an evaluation score, even if it is not a form as shown in these (4)-(6) Formula, As long as the “PI” value is improved, any formula may be used as long as the score is calculated so as to increase the score. In this embodiment, the operation evaluation system is installed in the sewage treatment plant. However, the operation evaluation system may be applied to plant facilities other than such a sewage treatment plant, for example, a water treatment plant.

<< Sixth Embodiment >> [Corresponding to Claim 7]

This is to display the driving evaluation point of the cost and the driving evaluation point of the PI value.

<Action>
Assuming a sewage treatment plant, the discharge water quality evaluation point calculation function calculates an operation evaluation point for the discharge water quality, for example, using an equation such as equation (2). In the operation cost evaluation point calculation function, for example, an operation evaluation point for the operation cost is calculated by an expression such as the expression (3). In the PI evaluation score calculation function, an operation evaluation score for the PI value is calculated by an expression such as the expression (4). These driving evaluation points are transmitted to the display device 5f and displayed.

<Effect>
(1) The operation evaluator 7 can evaluate the operation content from various viewpoints of operation cost, discharged water quality, and business index.

<< Seventh Embodiment >> [Corresponding to Claim 8]
<Configuration>
FIG. 10 is a block diagram showing a seventh embodiment of the driving evaluation system according to the present invention. In this figure, parts corresponding to those in FIG. 9 are given the same reference numerals.

  The operation evaluation system 1g shown in this figure is different from the operation evaluation system 1f shown in FIG. 9 in that the monitoring evaluation device 4g calculates the discharge water quality, the operation cost, the operation evaluation points for each PI index calculated by each evaluation point calculation function, The operation evaluation score of the detailed item of the index is calculated and displayed on the display device 5g.

<Action>
The detailed items of each index are, for example, water quality items such as SS, TN, TP, and COD if the water quality is discharged, and the evaluation score is calculated for each water quality item. For example, the evaluation score of SS is calculated by the following equation constituting equation (2).

Wl · (SSst−SS (t)) (7) In addition, the operation cost is calculated for each pump / pure and other chemicals such as coagulant and chemicals, and sludge generation amount. For example, the operation evaluation point of the pump is calculated by the following equation.

PP1 · Pump1 (t) (8) where Pump1 (t) is calculated from the electric energy of the pump 1 (the electric energy measurement value or the measurement value of the flow meter for measuring the pump discharge flow rate and the equipment performance) thing.)
pp1: Driving Evaluation Point Conversion Coefficient Also, the work index “PI” is calculated for each item of Tables 9 to 11 shown in FIGS. These can also be displayed as time-series data.

<Effect>
(1) Since detailed item data is displayed at the same time and displayed in time series, it becomes possible for the driving evaluator 7 to understand what caused the bad evaluation score when the driving evaluation score is bad, Attention and advice can be given to the operation manager 6.

<< Eighth Embodiment >> [Corresponding to Claim 9]
<Configuration>
FIG. 11 is a block diagram showing an eighth embodiment of the driving evaluation system according to the present invention. In this figure, parts corresponding to those in FIG. 9 are given the same reference numerals.

  The driving evaluation system 1h shown in this figure is different from the driving evaluation system 1f shown in FIG. 9 in that a calculation formula determination unit 12 for determining an evaluation point calculation formula is provided by using the inflow amount data as an input, and according to the inflow amount data. The evaluation point calculation formula used in the water quality evaluation point calculation function, the cost evaluation point calculation function, and the evaluation point calculation function of the monitoring device 4h is switched.

<Action>
Then, the calculation formula determination unit 12 that determines the evaluation score calculation formula selects a calculation formula (or model coefficient) in the evaluation score calculation function according to the measurement value of the inflow meter 13.

  For example, when the evaluation point of the discharged water quality is expressed by the above equation (2), SSst, CODst, TNst, TPst are different between “Q <Q1” and “Q> = Q1”, and “Q The value is set to be larger when> Q1 ″.

  In addition to treating sewage, the purpose of sewage treatment is to quickly remove rainwater. In a combined sewage treatment plant that treats both rainwater and sewage, when the flow rate increases, water treatment cannot be performed, and therefore, simple treatment, direct discharge, and the like are taken. In such a case, since the rainwater removal is prioritized over the water treatment, the discharged water quality is inevitably deteriorated. For this reason, when the flow rate is above a certain level, the water quality standard target value is slightly sweetened, so that even if the water quality slightly deteriorates, the discharge water quality evaluation point is calculated so that the operation evaluation point does not become low.

  In other words, it is possible to evaluate according to different evaluation criteria for fine weather and rainy weather. The same applies to the operation cost. If the inflow amount is larger than a certain level, many devices must be started up, and the operation cost per flow rate often increases. For this reason, when the flow rate exceeds a certain level (Q> = Q1), a calculation formula or model coefficient is selected so that the calculation point of the operation evaluation point of the operation cost is high, and the operation cost evaluation point is calculated. To do.

  For “Q1” as the reference for determining the flow rate, an equation is selected according to the planned water amount of the treatment plant.

<Effect>
(1) Since operation evaluation according to the flow rate is possible, it is possible to perform operation evaluation for rainy weather and for sunny weather.

<Modification>
In the eighth embodiment, “Ql” is set based on the planned water volume, but “Ql” may be set by another setting method. Further, the flow rate stage may be not only two stages but also more fragmented.

<Action>
Then, when the driving evaluator 7 clicks the annual comparison evaluation button on the screen, the trend graph or average value of the evaluation score of last year and the evaluation score of this year is displayed on the same screen for comparative evaluation.

<Effect>
(1) By comparing the evaluation score between last year and the evaluation score this year, it is possible to make a comparison under almost the same conditions, and it is possible to easily judge whether this year's driving is better than the previous year.

<Action>
Then, the operation evaluator 7 requested to perform the operation evaluation by the operation consignor 15 monitors the process information collected by the monitoring device 4a of the treatment facility, and performs evaluation from the viewpoint of water quality, risk, and cost. The result is reported to the operation contractor 15 on a monthly basis.

  If the driving method is bad, the driving consignor 15 is notified and the driving manager 6 is advised to improve.

<Effect>
(1) Since the operation evaluator 7 is constantly monitored, an incentive for the operation manager 6 to perform an operation that considers not only the cost but also the water quality and the risk works.

(2) Since the data is monitored online by the driving evaluator 7, it becomes a situation where the driving manager 6 cannot perform malicious data alteration.

(3) Since the improvement of water quality is evaluated by a third party, it is evaluated when the operation manager 6 improves the water environment. For this reason, environmental efforts will lead to an improvement in the image of operation managers, so there is an incentive to improve water quality.

<Modification>
In the twelfth embodiment, one driving evaluator 7 is selected and arranged at one place to perform driving evaluation. However, a plurality of driving evaluators 7 are selected and a plurality of locations are selected. It is also possible to arrange them for monitoring. Thereby, fraud due to rigging or the like can be made difficult to work.

<< 13th Embodiment >>
<Configuration>
FIG. 16 is a block diagram showing a thirteenth embodiment of the driving evaluation system according to the present invention. In this figure, parts corresponding to those in FIG. 1 are denoted by the same reference numerals.

According to the evaluation, a contract is made between the driving consignor 15 and the driving manager 6 so as to pay the driving manager 6 the driving improvement cost.

<Action>
Then, the operation evaluator 7 monitors the process information collected by the processing facility monitoring device 4a and the operation evaluation points calculated from the process information, and performs evaluation from the viewpoint of water quality, risk, and cost. The result is reported to the operation contractor 15 in units.

  If the driving method is bad, the driving consignor 15 is notified and the driving manager 6 is advised to improve.

  In addition, based on a contract between the driving manager 6 and the driving contractor 15, for example, the driving evaluation formula and how many yen the driving evaluation score is per point, an agreement for the standard evaluation point, etc. If the evaluation score is higher than a certain standard evaluation score, money is paid to the operation manager 6 in the form of operation improvement costs.

<Effect>
(1) Since the improvement of the operation improvement points will benefit the operation manager, an incentive to operate optimally from various viewpoints of cost, water quality and risk will work.

<Modification>
In the thirteenth embodiment, the driving improvement cost is paid only to the driving manager 6. However, a part (for example, about 5%) of the driving improvement cost may be paid to the driving evaluator 7. . Thereby, an incentive for the driving evaluator 7 to plan a driving improvement method works.

  Further, a contract may be made between the operation manager 6 and the operation entrustor 15 so that the operation manager 6 pays a fine to the operation entruster 15 when the reference evaluation score is not reached. As a result, an incentive that does not worsen driving works.

  Further, a contract may be made between the operation manager 6 and the operation consignor 15 so that the reference evaluation point is set according to the operation management result of the previous year. As a result, incentives to improve driving year by year work.

  Further, a contract may be made between the operation manager 6 and the operation consignor 15 so that the cost per operation evaluation point and the standard evaluation point are re-determined every period. This makes it possible to reflect technological innovations and changes in the equipment environment in the operation evaluation points.

  Furthermore, as the driving evaluator 7, a person who has no interest in the driving manager 15 and the driving manager 6 such as a university professor, NPO group, citizen, public organization, etc. may be selected. This enables fair evaluation.
