一般に、排水処理設備においては、流入する排水の水質変化に応じた運転が行われている。特に、下水処理場のように、流入する排水の水質及び水量が常に変化する排水処理設備においては、流入する排水の水質や水量に係る情報を予測して排水処理設備の運転を行うことが行われている。 In general, wastewater treatment equipment is operated in response to changes in the water quality of inflowing wastewater. Particularly in wastewater treatment facilities, such as sewage treatment plants, where the quality and quantity of inflowing wastewater constantly change, it is difficult to operate the wastewater treatment equipment by predicting information regarding the quality and quantity of incoming wastewater. It is being said.
例えば、特許文献１には、当日の天気予報および平日・休日別の情報に基づいて排水処理設備に流入する流入水量及び流入水質を予測し、この予測結果を用いて排水処理設備の運転を支援する運転支援装置が記載されている。 For example, in Patent Document 1, the amount and quality of inflowing water flowing into wastewater treatment equipment is predicted based on the day's weather forecast and information on weekdays and holidays, and the prediction results are used to support the operation of wastewater treatment equipment. Driving support devices are described.
しかしながら、排水処理設備に流入する水質は、雨水と人間の活動の結果として排出される排水とでは大きく異なる。したがって、特許文献１に記載されるように、天気予報という天候に係る情報と平日・休日別に係る情報を一緒にして取り扱うことでは、排水処理設備を最適に運転することができない。また、平日・休日別といったカレンダーに基づく情報だけでは、人間の活動に係る情報を正確に把握しているとはいえない。特に、突発的に人が集まるなど、規則性から外れる人間の活動に起因する排水量の増加に対応できないという問題がある。 However, the quality of water entering wastewater treatment facilities differs significantly between rainwater and wastewater discharged as a result of human activities. Therefore, as described in Patent Document 1, by handling weather-related information such as a weather forecast and information related to weekdays and holidays together, wastewater treatment equipment cannot be operated optimally. Furthermore, information based on calendars such as weekdays and holidays alone cannot accurately grasp information related to human activities. In particular, there is a problem in that they cannot cope with increases in wastewater caused by irregular human activities, such as sudden gatherings of people.

Further, the data acquisition unit 2 includes a first data acquisition unit 21 that acquires data related to human activities, and a second data acquisition unit 22 that acquires second data that acquires data related to weather.
データ取得部２における取得対象である人間の活動に関するデータとしては、人間が実際に活動していることに基づくデータとする。具体的には、携帯端末による位置情報、家電機器の使用状況、上水の使用状況、工場の稼働状況のうち、少なくとも１種類を含むことが好ましい。
また、人間の活動に関するデータを取得する第１データ取得手段２１としては、例えば、ＧＰＳの位置信号に関するデータ収集、上水の供給量や管網の圧力変化に関するデータ収集、家庭及び工場の消費電力のデータ収集を行うことが挙げられる。なお、データ収集に際しては、各データを管理する者（各通信会社、各水道局、各電力会社等）から提供を受けるものであってもよい。

Specifically, it is preferable to include at least one type of location information from a mobile terminal, the usage status of home appliances, the usage status of tap water, and the operating status of a factory.
In addition, the first data acquisition means 21 that acquires data related to human activities includes, for example, data collection related to GPS position signals, data collection related to water supply amount and pressure changes in pipe networks, and power consumption of households and factories. One example is collecting data. In addition, when collecting data, it may be provided by a person who manages each data (each communication company, each waterworks bureau, each electric power company, etc.).
Note that the data related to human activities may include data related to human activity predictions based on calendars such as weekdays and holidays, and data related to human activity predictions based on time zones such as morning, noon, and night.
データ取得部２における取得対象である天候に関するデータとしては、降雨予測や実際の降雨に基づくデータとする。また、運転管理対象である排水処理設備の立地に基づき、この排水処理設備に対して雨水の流入が予測される範囲における天候に関するデータを取得するものとする。
また、天候に関するデータを取得する第２データ取得手段２２としては、例えば、運転管理対象である排水処理設備のある地域及び排水処理設備に流入する下水管が設置された地域をメッシュ状に区分し、それぞれのメッシュごとに降雨予測及び実際の降雨測定量に関するデータ収集を行うことが挙げられる。なお、データ収集に際しては、気象データの収集・管理をする者（気象庁、民間の気象会社等）から提供を受けるものであってもよい。
The weather-related data to be acquired by the data acquisition unit 2 is data based on rainfall predictions and actual rainfall. Furthermore, based on the location of the wastewater treatment facility to be operated and managed, data regarding the weather in the range where rainwater is expected to flow into the wastewater treatment facility shall be acquired.
In addition, the second data acquisition means 22 that acquires weather-related data may, for example, divide the area where the wastewater treatment equipment, which is the target of operation management, is located and the area where the sewer pipes flowing into the wastewater treatment equipment are installed into a mesh pattern. , collecting data on rainfall prediction and actual rainfall measurements for each mesh. Note that data collection may be provided by a person who collects and manages weather data (such as the Japan Meteorological Agency or a private weather company).
データ取得部２によって収集されるデータは、実際の人間の活動に関するデータや、運転管理対象の排水処理設備に雨水が流入する範囲の実際の降雨量に関するデータである。したがって、規則的にパターン化されたデータとは異なり、突発的に人が増える事象や天候の急激な変化などに係るデータを収集することができる。 The data collected by the data acquisition unit 2 is data related to actual human activities and data related to the actual amount of rainfall in the range where rainwater flows into the wastewater treatment facility to be operated and managed. Therefore, unlike regularly patterned data, it is possible to collect data related to sudden increases in the number of people, sudden changes in weather, etc.
予測演算部３は、データ取得部２で得られたデータに基づき、排水処理設備に流入する排水の量及び時間に係る予測と、それに伴う排水処理設備１００に係る負荷の予測を行うものである。また、予測演算部３は、第１予測手段３１と、第２予測手段３２を備え、それぞれの予測手段に係る演算部３３、３４と、演算部３３、３４の結果を表示する表示部３５を備える。 The prediction calculation unit 3 predicts the amount and time of wastewater flowing into the wastewater treatment equipment and the associated load on the wastewater treatment equipment 100 based on the data obtained by the data acquisition unit 2. . The prediction calculation unit 3 also includes a first prediction unit 31 and a second prediction unit 32, calculation units 33 and 34 related to the respective prediction units, and a display unit 35 that displays the results of the calculation units 33 and 34.

第１予測手段３１は、第１データ取得手段２１で得られた人間の活動に関するデータに基づき、排水として排出される排水量及び排水が排出される時間を予測する。また、人間の活動に起因して排出される排水は、排水処理設備に係る負荷となるため、この負荷分を予測するものである。 The first prediction means 31 predicts the amount of wastewater to be discharged as wastewater and the time during which the wastewater will be discharged, based on the data regarding human activities obtained by the first data acquisition means 21. Furthermore, since wastewater discharged due to human activities places a load on wastewater treatment equipment, this load is estimated.
第１予測手段３１の演算部３３は、第１データ取得手段２１で得られたデータを基に解析を行うものである。例えば、解析に必要なプログラムをＣＰＵ等のプロセッサにより実行する計算装置である。 The calculation section 33 of the first prediction means 31 performs analysis based on the data obtained by the first data acquisition means 21. For example, it is a computing device that executes a program necessary for analysis using a processor such as a CPU.
演算部３３で用いる解析プログラムの内容は、第１データ取得手段２１で得られたデータを用いて排水として排出される排水量及び排水が排出される時間を予測し、排水処理設備に係る負荷を予測できるものであればよく、特に限定されない。
例えば、第１データ取得手段２１で得られたデータとして、携帯端末による位置情報を用いた場合、人間が集まっている場所や集まっている人間の数に係る情報を得ることができ、このとき発生する排水量だけではなく、排水が生じる時間及び発生した排水が排水処理設備に到達する時間についての予測が可能となる。また、第１データ取得手段２１で得られたデータとして、上水の使用状況を用いた場合、上水が使用された後に下水に流されて排水となる量及び時間を予測することが可能となる。また、排出された排水が下水管を介して排水処理設備に到達する時間についての予測も可能である。
このようにして、人間の活動に起因して排出される排水が排水処理設備に流入する量と時間を予測することができる。
The content of the analysis program used by the calculation unit 33 is to use the data obtained by the first data acquisition means 21 to predict the amount of wastewater to be discharged as wastewater and the time during which the wastewater will be discharged, and to predict the load on the wastewater treatment equipment. It is not particularly limited as long as it is possible.
For example, if location information from a mobile terminal is used as the data obtained by the first data acquisition means 21, it is possible to obtain information about the places where people are gathering and the number of people gathered. It becomes possible to predict not only the amount of wastewater that will be produced, but also the time that wastewater will occur and the time that the generated wastewater will reach the wastewater treatment facility. Furthermore, when the usage status of clean water is used as the data obtained by the first data acquisition means 21, it is possible to predict the amount and time when the clean water will be discharged into the sewer and become wastewater after being used. Become. It is also possible to predict the time it takes for discharged wastewater to reach wastewater treatment equipment via sewer pipes.
In this way, it is possible to predict the amount and time that wastewater discharged due to human activities will flow into the wastewater treatment facility.
さらに、この予測結果に基づき、排水処理設備において必要な処理能力を予測する。排水処理設備における必要な処理能力の予測については、過去の処理実績に基づくものであってもよく、処理に用いる処理槽の性能に基づくものであってもよい。 Furthermore, based on this prediction result, the necessary treatment capacity of the wastewater treatment facility is predicted. The prediction of the necessary treatment capacity in the wastewater treatment facility may be based on past treatment results or may be based on the performance of the treatment tank used for treatment.
また、第２予測手段３２は、第２データ取得手段２２で得られた天候に関するデータに基づき、排水処理設備に流入する流入水量及び流入時間を予測する。また、天候に起因して流入する雨水は、負荷となる有機物をほとんど含まないため、排水処理設備に係る負荷はほとんどない。したがって、排水処理設備に流入する水量の増加分を予測するものである。 Further, the second prediction means 32 predicts the amount and time of inflow water flowing into the wastewater treatment facility based on the weather-related data obtained by the second data acquisition means 22. In addition, rainwater that flows in due to the weather contains almost no organic matter that poses a load, so there is almost no load on wastewater treatment equipment. Therefore, the increase in the amount of water flowing into the wastewater treatment facility is predicted.
第２予測手段の演算部３４は、第２データ取得手段２２で得られたデータを基に解析を行うものである。例えば、解析に必要なプログラムをＣＰＵ等のプロセッサにより実行する計算装置である。なお、第１予測手段３１の演算部３３と第２予測手段３２の演算部３４は、別々の計算装置とするものであってもよく、同一の計算装置としてもよい。 The calculation unit 34 of the second prediction means performs analysis based on the data obtained by the second data acquisition means 22. For example, it is a computing device that executes a program necessary for analysis using a processor such as a CPU. Note that the calculation section 33 of the first prediction means 31 and the calculation section 34 of the second prediction means 32 may be separate calculation devices, or may be the same calculation device.
演算部３４で用いる解析プログラムの内容は、第２データ取得手段２２で得られたデータを用いて排水処理設備に流入する流入水量及び流入時間を予測し、排水処理設備に供給される水量を予測できるものであればよく、特に限定されない。
例えば、第２データ取得手段で得られたデータとして、メッシュ状に分割された地域ごとの降雨予測に基づく予測降雨量を用いた場合、排水処理設備に流入する流入水量に関する予測と、雨が降った地域から排水処理設備までの距離に基づき、雨水が排水処理設備に到達する時間についての予測が可能となる。
以上のように、雨水が排水処理設備に流入する量と時間の予測に基づき、排水処理設備に供給される全体の水量を予測する。
The content of the analysis program used by the calculation unit 34 is to predict the amount and time of inflow water flowing into the wastewater treatment equipment using the data obtained by the second data acquisition means 22, and predict the amount of water supplied to the wastewater treatment equipment. It is not particularly limited as long as it is possible.
For example, if the predicted rainfall amount based on the rainfall prediction for each area divided into meshes is used as the data obtained by the second data acquisition means, the prediction of the amount of inflow water flowing into the wastewater treatment facility and the amount of rain Based on the distance from the area to the wastewater treatment facility, it is possible to predict the time it takes for rainwater to reach the wastewater treatment facility.
As described above, the total amount of water to be supplied to the wastewater treatment equipment is predicted based on the prediction of the amount and time that rainwater will flow into the wastewater treatment equipment.
表示部３５は、演算部３３、３４における予測結果を数値あるいは画像として表示させるものである。これにより、予測演算部３による予測結果をオペレーターが確認することができる。また、オペレーターは、その後の排水処理設備に係る運転状態を把握し、それに基づいた対応を行うことが可能となる。 The display unit 35 displays the prediction results from the calculation units 33 and 34 as numerical values or images. Thereby, the operator can confirm the prediction result by the prediction calculation unit 3. In addition, the operator will be able to grasp the subsequent operating status of the wastewater treatment equipment and take action based on that.
運転制御部４は、予測演算部３で得られた予測結果に基づき、排水処理設備１００において必要な運転を制御するものである。また、運転制御部４は、第１運転制御手段４１と、第２運転制御手段４２を備える。 The operation control unit 4 controls necessary operations in the wastewater treatment facility 100 based on the prediction result obtained by the prediction calculation unit 3. Further, the operation control section 4 includes a first operation control means 41 and a second operation control means 42.
第１運転制御手段４１は、第１予測手段３１で得られた予測結果に基づき、排水処理設備１００に係る負荷に対応するために必要な運転を制御するものである。例えば、第１予測手段３１で予測された排水処理設備１００に係る負荷分に対応するため、排水Ｗを生物処理する生物処理槽１０３における処理能力を高めるものとすることができる。また、沈砂池１０１から調整池１０２へ排水を送る揚水ポンプＰ及び調整池１０２から生物処理槽１０３へ排水を送るバルブＢ１を制御して、生物処理槽１０３における処理量を制御するものとしてもよい。 The first operation control means 41 controls the operation necessary to cope with the load on the wastewater treatment equipment 100 based on the prediction result obtained by the first prediction means 31. For example, in order to cope with the load on the wastewater treatment equipment 100 predicted by the first prediction means 31, the processing capacity of the biological treatment tank 103 that biologically processes the wastewater W can be increased. Alternatively, the amount of treatment in the biological treatment tank 103 may be controlled by controlling the pump P that sends waste water from the settling tank 101 to the regulating tank 102 and the valve B1 that sends waste water from the regulating tank 102 to the biological treatment tank 103. .
生物処理槽１０３で行う生物処理は、好気処理、嫌気処理のいずれであってもよく、特に限定されない。例えば、好気処理の場合、生物処理槽１０３は、好気条件下で、活性汚泥を用いて有機物を分解するものとし、生物処理槽１０３には曝気装置及び撹拌装置を備えるものとしてもよい。このとき、曝気装置及び撹拌装置の駆動に係る制御を行うことで、生物処理槽における処理能力を高めるものとしてもよい。また、例えば、嫌気処理の場合、生物処理槽１０３は、嫌気条件下で、酸生成菌及びメタン生成菌によるメタン発酵により有機物を分解するものとし、生物処理槽１０３には酸発酵槽及びメタン発酵槽を備えるものとしてもよい。このとき、それぞれの槽における温度管理や撹拌装置の駆動に係る制御を行うことで、生物処理槽１０３における処理能力を高めるものとしてもよい。また、好気処理及び嫌気処理を組み合わせるものであってもよい。 The biological treatment performed in the biological treatment tank 103 may be either aerobic treatment or anaerobic treatment, and is not particularly limited. For example, in the case of aerobic treatment, the biological treatment tank 103 decomposes organic matter using activated sludge under aerobic conditions, and the biological treatment tank 103 may be equipped with an aeration device and a stirring device. At this time, the processing capacity of the biological treatment tank may be increased by controlling the driving of the aeration device and the stirring device. For example, in the case of anaerobic treatment, the biological treatment tank 103 decomposes organic matter by methane fermentation by acid-producing bacteria and methane-producing bacteria under anaerobic conditions. It may also be equipped with a tank. At this time, the processing capacity in the biological treatment tank 103 may be increased by controlling the temperature in each tank and driving the stirring device. Alternatively, a combination of aerobic treatment and anaerobic treatment may be used.
また、生物処理槽１０３に、微生物の活性を向上させるための栄養源となる物質を添加する添加手段を設けるものとしてもよい。このとき、第１運転制御手段４１によって、添加手段により添加される物質の量を調整することで、生物処理槽１０３における処理能力を高めるものとしてもよい。 Furthermore, the biological treatment tank 103 may be provided with an addition means for adding a substance that serves as a nutrient source to improve the activity of microorganisms. At this time, the treatment capacity in the biological treatment tank 103 may be increased by adjusting the amount of the substance added by the addition means by the first operation control means 41.
排水処理設備１００は、生物処理槽１０３を複数設けるものとしてもよい。例えば、第１予測手段３１による予測結果に基づく排水量及び排水処理設備に係る負荷が、１台の生物処理槽１０３における処理能力を超える場合、第１運転制御手段によって、稼働する生物処理槽１０３の台数を増加させるものであってもよい。
また、第１予測手段３１による予測結果に基づく排水量及び排水処理設備に係る負荷が、排水処理設備１００における処理能力を超える場合、第１運転制御手段によって、排水の一部を他の排水処理設備に供給するものとしてもよい。
The wastewater treatment facility 100 may include a plurality of biological treatment tanks 103. For example, when the amount of wastewater and the load on the wastewater treatment equipment based on the prediction result by the first prediction means 31 exceed the processing capacity of one biological treatment tank 103, the first operation control means controls the amount of biological treatment tank 103 in operation. The number of units may be increased.
Further, when the amount of wastewater and the load on the wastewater treatment equipment based on the prediction result by the first prediction means 31 exceed the processing capacity of the wastewater treatment equipment 100, the first operation control means transfers a part of the wastewater to other wastewater treatment equipment. It may also be supplied to
また、第２運転制御手段４２は、第２予測手段３２で得られた予測結果に基づき、排水処理設備に流入する水量に対応するために必要な運転を制御するものである。雨水中には有機物がほとんど含まれないため、雨水により増加した流入水量は、排水処理設備に係る負荷を増加させるものではない。したがって、第２予測手段３２に基づき増加した排水Ｗに対しては、生物処理槽１０３による生物処理を必要としない場合もある。 Further, the second operation control means 42 controls the operation necessary to cope with the amount of water flowing into the wastewater treatment facility based on the prediction result obtained by the second prediction means 32. Since rainwater contains almost no organic matter, the increased amount of inflow water due to rainwater does not increase the load on wastewater treatment equipment. Therefore, the increased wastewater W based on the second prediction means 32 may not require biological treatment by the biological treatment tank 103.
排水処理設備１００に流入した排水Ｗに対して、生物処理が必要であるか、不要であるかについては、生物処理を行う前に排水の水質について測定することにより判断が可能である。
例えば、調整池１０２にＢＯＤ計を設け、ＢＯＤ計の値が所定値以下である場合、第２運転制御手段４２として、調整池１０２から消毒処理槽１０４へ排水を送るバルブＢ２の駆動を制御して、流入した排水Ｗを消毒処理槽１０４に直接供給することが挙げられる。なお、ＢＯＤ計の所定値としては、公共水域に放出可能な値を設定することが好ましい。これにより、雨水により一時的に増加した排水に対して、必要最低限の処理を行って排水処理設備１００から処理水Ｗ１として公共水域へ放出することができる。その結果、排水処理設備１００における処理速度が上がり、排水処理設備１００において排水Ｗの受け入れ能力に余裕を持たせることが可能となる。
Whether biological treatment is necessary or unnecessary for the wastewater W flowing into the wastewater treatment facility 100 can be determined by measuring the water quality of the wastewater before performing the biological treatment.
For example, if a BOD meter is provided in the regulating reservoir 102 and the value of the BOD meter is below a predetermined value, the second operation control means 42 controls the driving of the valve B2 that sends wastewater from the regulating reservoir 102 to the disinfection treatment tank 104. One example of this is to directly supply the inflowing wastewater W to the disinfection treatment tank 104. Note that it is preferable to set the predetermined value of the BOD meter to a value that can be released into public waters. Thereby, the wastewater temporarily increased due to rainwater can be treated to the minimum necessary level and then released from the wastewater treatment facility 100 into a public water area as treated water W1. As a result, the processing speed in the wastewater treatment equipment 100 increases, and the wastewater treatment equipment 100 can have a sufficient capacity for receiving the wastewater W.
また、第２運転制御手段４２によって、消毒処理槽１０４に設けられる次亜塩素酸ナトリウム等の消毒液を添加する消毒液添加手段についても制御を行うものとしてもよい。これにより、流入する水量に対して適切な量の消毒液を添加することが可能となる。 Further, the second operation control means 42 may also control a disinfectant adding means provided in the disinfection treatment tank 104 for adding a disinfectant such as sodium hypochlorite. This makes it possible to add an appropriate amount of disinfectant to the amount of water flowing in.
一方、例えば、調整池１０２のＢＯＤ計の値が所定値以上である場合、第２運転制御手段４２としては、第１運転制御手段４１と同様に、生物処理槽１０３における処理能力を高めるものとすることが好ましい。このとき、１台の生物処理槽１０３における処理能力を高めることとしてもよく、複数台の生物処理槽１０３を稼働させることで処理能力を高めるものとしてもよい。
また、第２予測手段３２によって予測された流入水量が、排水処理設備１００の許容量を超える場合、第２運転制御手段４２によって、流入する排水の一部を他の排水処理設備に供給するものとしてもよい。
On the other hand, for example, when the value of the BOD meter of the regulating pond 102 is equal to or higher than a predetermined value, the second operation control means 42, like the first operation control means 41, increases the processing capacity of the biological treatment tank 103. It is preferable to do so. At this time, the processing capacity of one biological treatment tank 103 may be increased, or the processing capacity may be increased by operating a plurality of biological treatment tanks 103.
Further, when the amount of inflowing water predicted by the second prediction means 32 exceeds the allowable amount of the wastewater treatment equipment 100, the second operation control means 42 supplies a part of the inflowing wastewater to other wastewater treatment equipment. You can also use it as
以上のように、本実施態様における運転制御装置１は、まず、データ取得部２によって人間の活動に関するデータと天候に関するデータを別々に取得する。そして、予測演算部３においてそれぞれのデータに基づく排水量や排水が排水処理設備に流入する時間を予測し、排水処理設備に係る負荷及び水量の増加分を予測する。さらに、予測演算部３による予測結果に基づき、運転制御部４によって排水処理設備の運転を制御する。
これにより、排水処理設備の運転において、負荷に対応する運転と、水量の増加分に対応する運転とを区別して、必要なときに必要なだけ稼働させることができ、排水処理設備の運転状態を最適に管理することが可能となる。
As described above, in the operation control device 1 according to the present embodiment, first, the data acquisition unit 2 separately acquires data regarding human activities and data regarding the weather. Then, the prediction calculation unit 3 predicts the amount of waste water and the time at which the waste water flows into the waste water treatment equipment based on the respective data, and predicts the load related to the waste water treatment equipment and the increase in water amount. Further, based on the prediction result by the prediction calculation unit 3, the operation control unit 4 controls the operation of the wastewater treatment equipment.
As a result, when operating wastewater treatment equipment, it is possible to distinguish between operation that corresponds to the load and operation that corresponds to the increase in water volume, and to operate the wastewater treatment equipment as much as necessary when necessary. This enables optimal management.
〔第２の実施態様〕
図３は、本発明の第２の実施態様における排水処理設備の運転制御装置を示す概略説明図である。また、図４は、本発明の第２の実施態様における排水処理設備の運転制御装置に係る制御を示すフロー図である。
第２の実施態様に係る排水処理設備の運転制御装置１ｂは、図３に示すように、第１の実施態様に係る排水処理設備の運転制御装置１ａにおいて、第１予測手段３１と第２予測手段３２によって得られた予測結果に対して、排水処理設備１００の運転への影響に応じた優先順位を判断し、運転制御部４を制御する判断部５を設けるものである。なお、第１の実施態様の構造と同じものについては、説明を省略する。
[Second embodiment]
FIG. 3 is a schematic explanatory diagram showing an operation control device for wastewater treatment equipment in a second embodiment of the present invention. Moreover, FIG. 4 is a flowchart showing control related to the operation control device for wastewater treatment equipment in the second embodiment of the present invention.
As shown in FIG. 3, the operation control device 1b for wastewater treatment equipment according to the second embodiment includes a first prediction means 31 and a second prediction means 31 in the operation control device 1a for wastewater treatment equipment according to the first embodiment. A determination section 5 is provided which determines the priority order according to the influence on the operation of the wastewater treatment equipment 100 based on the prediction result obtained by the means 32, and controls the operation control section 4. Note that the description of the same structures as those of the first embodiment will be omitted.
判断部５は、第１予測手段３１及び第２予測手段３２の予測結果が入力可能に接続されている。また、判断部５は、第１運転制御手段４１及び第２運転制御手段４２に対して制御可能に接続されている。
判断部５は、第１予測手段３１及び第２予測手段３２の予測結果を基に解析を行うものである。例えば、解析に必要なプログラムをＣＰＵ等のプロセッサにより実行する計算装置である。なお、判断部５は、第１演算部３３及び第２演算部３４における計算装置と同一の装置としてもよく、別の計算装置とするものであってもよい。
The judgment unit 5 is connected to be able to receive the prediction results of the first prediction means 31 and the second prediction means 32. Further, the determination unit 5 is controllably connected to the first operation control means 41 and the second operation control means 42.
The judgment unit 5 performs analysis based on the prediction results of the first prediction means 31 and the second prediction means 32. For example, it is a computing device that executes a program necessary for analysis using a processor such as a CPU. Note that the determination section 5 may be the same computing device as the first computing section 33 and the second computing section 34, or may be a different computing device.
判断部５は、第１予測手段３１と第２予測手段３２の予測結果に基づき、第１運転制御手段４１と第２運転制御手段４２のいずれを優先させるべきであるかを判断し、その判断結果に基づき、第１運転制御手段４１及び第２運転制御手段４２を制御する。このとき、判断の基準としては、処理が不十分な排水を系外に放出させないことを第一とする。
例えば、第２予測手段３２によって、雨水に基づく流入水量が増加することが予測され、それに基づいて第２運転制御手段４２を稼働させた場合、ＢＯＤ値が所定値以下であれば生物処理槽を介さずに排水処理が進行する。一方、その後、第１予測手段３１によって、人間の活動に起因する排水量が増加することが予測された場合、そのまま第２運転制御手段４２に基づく運転を継続すると、生物処理が必要な排水が生物処理槽１０３を介さない排水処理に供されてしまう可能性がある。したがって、第１予測手段３１の予測結果として排水量の増加が予測された場合、この予測結果に基づく排水が排水処理設備に到達するよりも前に、第２運転制御手段４２に基づく排水処理設備の運転を切り替える必要がある。ここで、判断部５において、第１予測手段３１における予測結果を第２予測手段３２における予測結果より優先させるように判断し、その判断結果に基づき、それぞれの運転制御部４を制御するものとする。これにより、未処理の排水を系外に排出することを防止することができる。
The determination unit 5 determines which of the first operation control means 41 and the second operation control means 42 should be prioritized based on the prediction results of the first prediction means 31 and the second prediction means 32, and makes the determination. Based on the results, the first operation control means 41 and the second operation control means 42 are controlled. At this time, the first criterion for judgment is to prevent insufficiently treated wastewater from being released outside the system.
For example, if the second prediction means 32 predicts that the amount of inflow water based on rainwater will increase and the second operation control means 42 is operated based on this, the biological treatment tank is activated if the BOD value is below a predetermined value. Wastewater treatment proceeds without intervention. On the other hand, if the first prediction means 31 subsequently predicts that the amount of wastewater caused by human activities will increase, if the operation based on the second operation control means 42 is continued, the wastewater that requires biological treatment will be There is a possibility that the waste water is treated without going through the treatment tank 103. Therefore, when an increase in the amount of wastewater is predicted as a prediction result of the first prediction means 31, before the wastewater based on this prediction result reaches the wastewater treatment equipment, the wastewater treatment equipment based on the second operation control means 42 is activated. I need to change my driving style. Here, the determination unit 5 determines to give priority to the prediction result of the first prediction means 31 over the prediction result of the second prediction means 32, and controls each operation control unit 4 based on the determination result. do. This can prevent untreated wastewater from being discharged outside the system.
なお、上述した実施態様は運転制御装置の一例を示すものである。本発明に係る運転制御装置は、上述した実施態様に限られるものではなく、請求項に記載した要旨を変更しない範囲で、上述した実施態様に係る運転制御装置を変形してもよい。 In addition, the embodiment mentioned above shows an example of an operation control device. The operation control device according to the present invention is not limited to the embodiments described above, and the operation control device according to the embodiments described above may be modified without changing the gist of the claims.
例えば、本実施態様における予測演算部において得られた予測結果が平均よりも低い値であった場合、運転制御部によって、排水処理設備の運転に係る電力等を抑制するように運転を制御するものであってもよい。これにより、少ない排水量や低負荷の排水に対して過度な処理能力を発揮することがなく、排水処理設備の最適な運転が可能となる。 For example, if the prediction result obtained by the prediction calculation unit in this embodiment is a value lower than the average, the operation control unit controls the operation so as to suppress the electric power etc. related to the operation of the wastewater treatment equipment. It may be. As a result, the wastewater treatment equipment can be operated optimally without exhibiting excessive treatment capacity for small amounts of wastewater or low-load wastewater.
また、排水処理設備に各種水質計を設置し、水質計の測定結果に基づき本実施態様における運転制御部における制御を行うものとしてもよい。これにより、排水処理設備に流入する排水に係る予測結果だけではなく、排水処理設備での処理の進行状態に係るデータも併せて利用することができ、より排水処理設備の運転状態を最適に管理することが可能となる。 Alternatively, various water quality meters may be installed in the wastewater treatment facility, and the operation control unit in this embodiment may perform control based on the measurement results of the water quality meters. This makes it possible to use not only prediction results related to wastewater flowing into wastewater treatment equipment, but also data related to the progress of treatment in wastewater treatment equipment, allowing for more optimal management of the operating status of wastewater treatment equipment. It becomes possible to do so.
本発明の排水処理設備の運転制御装置及び運転制御方法は、人間の活動及び天候によって処理する排水量が変化する下水処理場等の排水処理設備の運転管理において好適に利用されるものである。 The operation control device and operation control method for wastewater treatment equipment of the present invention are suitably used in the operation management of wastewater treatment equipment such as sewage treatment plants where the amount of wastewater to be treated changes depending on human activities and weather.
