Description
本発明は、排水処理設備の運転状態を最適に管理するための運転制御装置及び運転制御方法に関するものである。 The present invention relates to an operation control device and an operation control method for optimally managing the operation state of wastewater treatment equipment.
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。 Generally, wastewater treatment equipment is operated according to changes in the quality of the inflowing wastewater. In particular, in sewage treatment facilities where the quality and amount of inflowing wastewater are constantly changing, such as sewage treatment plants, it is possible to predict the information related to the quality and amount of inflowing wastewater and operate the wastewater treatment equipment. It has been drained.
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, Patent Document 1 predicts the amount of inflow water and the quality of inflow water flowing into a wastewater treatment facility based on the weather forecast of the day and information for each weekday / holiday, and supports the operation of the wastewater treatment facility using this prediction result. The driving support device to be used is 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 flowing into wastewater treatment equipment differs greatly between rainwater and wastewater discharged as a result of human activity. Therefore, as described in Patent Document 1, it is not possible to optimally operate the wastewater treatment facility by handling the information related to the weather such as the weather forecast and the information related to each weekday / holiday together. In addition, it cannot be said that the information related to human activities is accurately grasped only by the information based on the calendar such as weekdays and holidays. In particular, there is a problem that it is not possible to cope with an increase in the amount of wastewater caused by human activities that deviate from regularity, such as sudden gathering of people.

The purpose of the present invention is to provide an operation control device and an operation control method for wastewater treatment equipment.
本発明者は、上記の課題について鋭意検討した結果、排水処理設備の運転状態を最適に管理するための運転において、人間の活動に係るデータと天候に関するデータを別に取得し、それぞれのデータに基づく予測及び運転制御を行うことで、排水処理設備の運転状態を最適に管理することが可能になることを見出して、本発明を完成した。

Specifically, it is preferable to include at least one of the location information by the mobile terminal, the usage status of home appliances, the usage status of clean water, and the operating status of the factory.
The first data acquisition means 21 for acquiring data on human activities includes, for example, data collection on GPS position signals, data collection on clean water supply amount and pressure change in pipe network, power consumption in homes and factories. Data collection is mentioned. In addition, when collecting data, it may be provided by a person who manages each data (each communication company, each water service bureau, each electric power company, etc.).
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 data related to the weather to be acquired by the data acquisition unit 2 is data based on rainfall prediction or actual rainfall. In addition, based on the location of the wastewater treatment facility that is the target of operation management, data on the weather in the range where rainwater inflow is predicted for this wastewater treatment facility shall be acquired.

Therefore, unlike the regularly patterned data, it is possible to collect data related to events such as sudden increase in the number of people and sudden changes in the weather.
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。 Based on the data obtained by the data acquisition unit 2, the prediction calculation unit 3 predicts the amount and time of wastewater flowing into the wastewater treatment facility and predicts the load of the wastewater treatment facility 100. ..

In addition, the wastewater discharged due to human activities is a load related to the wastewater treatment equipment, so this load is predicted.
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 unit 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 required for analysis by 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 predicts the amount of wastewater discharged as wastewater and the time during which the wastewater is discharged using the data obtained by the first data acquisition means 21, and predicts the load related to the wastewater treatment equipment. Anything that can be done is not particularly limited.
For example, when the position information by the mobile terminal is used as the data obtained by the first data acquisition means 21, it is possible to obtain information related to the place where humans are gathered and the number of humans gathered, which is generated at this time. It is possible to predict not only the amount of wastewater to be discharged, but also the time when wastewater is generated and the time when the generated wastewater reaches the wastewater treatment facility. Further, 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 of drainage after the clean water is used and then flushed into the sewage. Become. It is also possible to predict the time it takes for the discharged wastewater to reach the wastewater treatment facility via the sewer pipe.
In this way, it is possible to predict the amount and time of wastewater discharged due to human activity to 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 required treatment capacity in the wastewater treatment facility is predicted. The prediction of the required treatment capacity in the wastewater treatment facility may be based on the past treatment results or the performance of the treatment tank used for the 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 predicting means 32 predicts the inflow water amount and the inflow time flowing into the wastewater treatment facility based on the data on the weather obtained by the second data acquisition means 22. In addition, since the rainwater that flows in due to the weather contains almost no organic matter that becomes a load, there is almost no load on the 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 required for analysis by a processor such as a CPU. The calculation unit 33 of the first prediction means 31 and the calculation unit 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 in the calculation unit 34 predicts the amount of inflow water and the inflow time flowing into the wastewater treatment equipment using the data obtained by the second data acquisition means 22, and predicts the amount of water supplied to the wastewater treatment equipment. Anything that can be done is not particularly limited.
For example, when 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 regarding the inflow water amount flowing into the wastewater treatment facility and the rain fall. 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 supplied to the wastewater treatment facility is predicted based on the prediction of the amount and time of rainwater flowing into the wastewater treatment facility.
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 of the calculation units 33 and 34 as numerical values or images. As a result, the operator can confirm the prediction result by the prediction calculation unit 3. In addition, the operator can grasp the operating state of the wastewater treatment equipment after that and take measures based on it.
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 the operation required in the wastewater treatment facility 100 based on the prediction result obtained by the prediction calculation unit 3. Further, the operation control unit 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 for dealing with the load related to 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 amount related to the wastewater treatment facility 100 predicted by the first prediction means 31, the treatment capacity in the biological treatment tank 103 for biologically treating the wastewater W can be increased. Further, the pump P for sending drainage from the sand basin 101 to the regulating pond 102 and the valve B1 for sending drainage from the regulating pond 102 to the biological treatment tank 103 may be controlled to control the treatment amount in 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 may decompose organic substances using activated sludge under aerobic conditions, and the biological treatment tank 103 may be provided with an aeration device and a stirring device. At this time, the processing capacity in the biological treatment tank may be increased by controlling the driving of the aeration device and the stirring device. Further, for example, in the case of anaerobic treatment, the biological treatment tank 103 decomposes organic substances by methane fermentation by acid-producing bacteria and methane-producing bacteria under anaerobic conditions, and the biological treatment tank 103 has an acid fermentation tank and methane fermentation. It may be provided with a tank. At this time, the processing capacity of the biological treatment tank 103 may be increased by controlling the temperature in each tank and controlling the driving of the stirring device. Further, it may be a combination of aerobic treatment and anaerobic treatment.
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。 Further, the biological treatment tank 103 may be provided with an addition means for adding a substance serving as a nutrient source for improving 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 be provided with a plurality of biological treatment tanks 103. For example, when the amount of wastewater based on the prediction result by the first prediction means 31 and the load related to the wastewater treatment equipment exceed the treatment capacity of one biological treatment tank 103, the biological treatment tank 103 operated by the first operation control means. It may increase the number of units.
Further, when the amount of wastewater based on the prediction result by the first prediction means 31 and the load related to the wastewater treatment equipment exceed the treatment capacity of the wastewater treatment equipment 100, a part of the wastewater is partially partially discharged by the first operation control means to another wastewater treatment equipment. It may 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 required 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 the rainwater contains almost no organic matter, the amount of inflow water increased by the rainwater does not increase the load on the wastewater treatment equipment. Therefore, the wastewater W increased 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 or not biological treatment is necessary for the wastewater W flowing into the wastewater treatment facility 100 can be determined by measuring the water quality of the wastewater before the biological treatment.
For example, when a BOD meter is provided in the regulating pond 102 and the value of the BOD meter is equal to or less than a predetermined value, the second operation control means 42 controls the drive of the valve B2 that sends wastewater from the regulating pond 102 to the disinfection treatment tank 104. Then, the inflowing wastewater W may be directly supplied to the disinfection treatment tank 104. As a predetermined value of the BOD meter, it is preferable to set a value that can be released into public water areas. As a result, the wastewater temporarily increased by rainwater can be treated at the minimum necessary and discharged from the wastewater treatment facility 100 to the public water area as treated water W1. As a result, the treatment speed in the wastewater treatment facility 100 is increased, and the wastewater treatment facility 100 can have a margin in the 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 the disinfectant solution adding means for adding the disinfectant solution such as sodium hypochlorite provided in the disinfection treatment tank 104. This makes it possible to add an appropriate amount of disinfectant solution to the amount of inflowing water.
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 is intended to increase the processing capacity in the biological treatment tank 103 as in the first operation control means 41. It is preferable to do so. At this time, the processing capacity in 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 inflow water amount predicted by the second prediction means 32 exceeds the allowable amount of the wastewater treatment equipment 100, a part of the inflow wastewater is supplied to another wastewater treatment equipment by the second operation control means 42. May be.
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, the operation control device 1 in the present embodiment first acquires data on human activities and data on weather separately by the data acquisition unit 2. Then, the prediction calculation unit 3 predicts the amount of wastewater based on each data and the time when the wastewater flows into the wastewater treatment facility, and predicts the load related to the wastewater treatment facility and the increase in the amount of water. Further, the operation of the wastewater treatment equipment is controlled by the operation control unit 4 based on the prediction result by the prediction calculation unit 3.
As a result, in the operation of the wastewater treatment equipment, it is possible to distinguish between the operation corresponding to the load and the operation corresponding to the increase in the amount of water, and to operate as much as necessary when necessary, and the operating state of the wastewater treatment equipment can be checked. Optimal management is possible.
〔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 view showing an operation control device for wastewater treatment equipment according to the second embodiment of the present invention. Further, FIG. 4 is a flow chart showing control according to the operation control device of the wastewater treatment facility according to the second embodiment of the present invention.
As shown in FIG. 3, the operation control device 1b of the wastewater treatment equipment according to the second embodiment has the first prediction means 31 and the second prediction in the operation control device 1a of the wastewater treatment equipment according to the first embodiment. A determination unit 5 is provided to determine the priority order according to the influence on the operation of the wastewater treatment facility 100 with respect to the prediction result obtained by the means 32 and control the operation control unit 4. The same description as that 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 determination unit 5 is connected so that the prediction results of the first prediction means 31 and the second prediction means 32 can be input. Further, the determination unit 5 is controllably connected to the first operation control means 41 and the second operation control means 42.
The determination unit 5 analyzes 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 required for analysis by a processor such as a CPU. The determination unit 5 may be the same device as the calculation device in the first calculation unit 33 and the second calculation unit 34, or may be another calculation 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 determines that. Based on the result, the first operation control means 41 and the second operation control means 42 are controlled. At this time, the first criterion for judgment is not to discharge insufficiently treated wastewater to the outside of the system.
For example, when the second predictive 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 the prediction, if the BOD value is equal to or less than a predetermined value, the biological treatment tank is used. Wastewater treatment proceeds without intervention. On the other hand, after that, when the first predictive means 31 predicts that the amount of wastewater due to human activity will increase, if the operation based on the second operation control means 42 is continued as it is, the wastewater requiring biological treatment will be biological. There is a possibility that it will be used for wastewater treatment that does not go through the treatment tank 103. Therefore, when an increase in the amount of wastewater is predicted as the prediction result of the first prediction means 31, the wastewater treatment equipment based on the second operation control means 42 before the wastewater based on this prediction result reaches the wastewater treatment equipment. It is necessary to switch the operation. Here, the determination unit 5 determines that the prediction result of the first prediction means 31 has priority over the prediction result of the second prediction means 32, and controls each operation control unit 4 based on the judgment result. do. This makes it possible to prevent untreated wastewater from being discharged to the outside of 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。 The above-described embodiment shows an example of the operation control device. The operation control device according to the present invention is not limited to the above-described embodiment, and the operation control device according to the above-described embodiment may be modified without changing the gist described in 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, when the prediction result obtained by the prediction calculation unit in this embodiment is lower than the average value, the operation control unit controls the operation so as to suppress the electric power and the like related to the operation of the wastewater treatment facility. May be. As a result, the wastewater treatment equipment can be optimally operated without exerting an excessive treatment capacity for a small amount of wastewater and a 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。 Further, various water quality meters may be installed in the wastewater treatment facility, and the operation control unit in the present embodiment may perform control based on the measurement results of the water quality meters. As a result, not only the prediction results related to the wastewater flowing into the wastewater treatment equipment but also the data related to the progress status of the treatment at the wastewater treatment equipment can be used together, and the operating condition of the wastewater treatment equipment can be managed more optimally. It becomes possible to do.
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 of the wastewater treatment equipment of the present invention are suitably used in the operation management of wastewater treatment equipment such as a sewage treatment plant where the amount of wastewater to be treated changes depending on human activity and weather.
