Description
本発明は、汚泥削減手段の運用方法と装置に関し、詳しくは、上、下水の水処理の専用業者、あるいは水処理を必要としている業者などをユーザとして、水処理後、主として汚水処理後の汚泥を削減する汚泥削減手段を使用に供し、汚泥削減による効果実績に見合って課金することで、汚泥削減手段の運用を図る汚泥削減手段の運用方法と装置に関するものである。 The present invention relates to an operation method and apparatus for sludge reduction means, and more specifically, sludge after water treatment, mainly after sewage treatment, using a dedicated trader for sewage water treatment or a trader in need of water treatment as a user. The present invention relates to an operation method and an apparatus for sludge reduction means that uses sludge reduction means for reducing the amount of sludge and charges it in accordance with the actual results of sludge reduction.
このような汚泥削減手段の運用方法と装置は、例えば、下記の特許文献１が汚泥減量化サービス方法および汚泥減量化サービスシステムとして開示している。特許文献１が開示しているサービス技術は、水処理設備に対して発生汚泥を減量化する汚泥減量化設備や、この汚泥減量化設備へのエネルギー供給設備を提供し、前記汚泥減量化設備による汚泥の減少量を演算手段で求めたり、汚泥減量化設備へのエネルギー供給量を蒸気流量計などで測定したりして、これら汚泥減少量やエネルギー供給量に基づいて課金手段により得たサービス料金を、水処理設備を有する事業者に請求するようにしている。 Such a sludge reduction means operating method and apparatus are disclosed, for example, in the following Patent Document 1 as a sludge reduction service method and a sludge reduction service system. The service technology disclosed in Patent Document 1 provides a sludge reduction facility for reducing generated sludge to a water treatment facility and an energy supply facility for the sludge reduction facility. The service charge obtained by the billing means based on the sludge reduction amount and energy supply amount by calculating the sludge reduction amount with the calculation means and measuring the energy supply amount to the sludge reduction equipment with a steam flow meter etc. Is billed to a business operator having a water treatment facility.
これにより、水処理業者にとっては初期投資を要することなく汚泥処分費の削減を行うことができ、サービス提供者は汚泥減量化によって発生したサービス料金を得ることができ、さらに、汚泥減量化設備の普及がすすみ、汚泥の最終処分量が減少し、さらに汚泥の処分にかかるエネルギー費用を節約することができるとしている。併せ、特許文献１は、汚泥の減少量を演算するのに、汚泥排出出口に設けた汚泥濃度計と汚泥流量計で汚泥排出量を計測する手法を開示している。 As a result, the water treatment company can reduce the sludge disposal cost without requiring an initial investment, the service provider can obtain the service fee generated by the sludge reduction, and the sludge reduction equipment It is said that the spread of the sludge will reduce the final disposal amount of sludge, and further save energy costs for sludge disposal. In addition, Patent Document 1 discloses a method of measuring the sludge discharge amount with a sludge concentration meter and a sludge flow meter provided at the sludge discharge outlet in order to calculate the sludge reduction amount.
しかし、特許文献１に開示の手法は汚泥減少量を求めるのに、汚泥減少前の基準値を「汚泥削減手段を停止したときの汚泥排出量」としているため、基準値を求めるために汚泥削減手段を停止する必要がある。また、そのような基準値は、下水の処理水の質の変化、下水の量の変化、季節による曝気槽の微生物活性度の変化により変動するので、正確な基準値を得るためには汚泥削減手段を度々停止する必要がある。このため、汚泥削減手段を停止している期間は汚泥削減ができないばかりでなく、汚泥削減手段が効果を発揮するにはある程度の連続運転が必要で、装置を度々停止させることは、装置の汚泥削減効率の低下を招く。 However, since the method disclosed in Patent Document 1 obtains the sludge reduction amount, the reference value before sludge reduction is “sludge discharge amount when the sludge reduction means is stopped”, so sludge reduction is required to obtain the reference value. It is necessary to stop the means. In addition, such reference values fluctuate due to changes in the quality of treated sewage water, changes in the amount of sewage, seasonal changes in the microbial activity of the aeration tank, and sludge reduction is necessary to obtain accurate reference values. It is necessary to stop the means frequently. For this reason, not only sludge reduction is not possible during the period when the sludge reduction means is stopped, but a certain amount of continuous operation is required for the sludge reduction means to be effective. Reduction efficiency is reduced.
本発明は、上記のような問題点に鑑み、汚泥削減手段を稼働しながら汚泥の削減量を、種々な条件変化にも対応して正確に求め、汚泥削減効率の低下なしに適正な課金を設定して請求できるようにして汚泥削減手段の運用が図れる汚泥削減手段の運用方法と装置を提供することを目的とするものである。 In view of the above problems, the present invention accurately obtains a sludge reduction amount corresponding to various changes in conditions while operating sludge reduction means, and makes an appropriate charge without reducing sludge reduction efficiency. An object of the present invention is to provide an operation method and apparatus for sludge reduction means that can be set and billed to operate the sludge reduction means.
上記のような課題を解決するために、本発明の汚泥削減手段の運用方法は、汚水処理後の汚泥を削減する汚泥削減手段を汚水処理施設利用者をユーザとして使用に提供し、前記汚泥削減手段の汚泥投入入口での投入汚泥に関する計測値から演算した汚泥投入量と、前
記汚泥削減手段の汚泥排出出口での排出汚泥に関する計測値から演算した汚泥排出量と、に基づき汚泥削減量を演算し、前記演算された汚泥削減量から削減効果金額を演算し、前記演算された削減効果金額に応じた対価を前記ユーザに請求することを特徴とするものである。
In order to solve the above-described problems, the sludge reduction means operating method of the present invention provides a sludge reduction means for reducing sludge after sewage treatment as a user of a sewage treatment facility user. The sludge reduction amount is calculated based on the sludge input amount calculated from the measured value of the sludge input at the sludge input port of the means and the sludge discharge amount calculated from the measured value of the sludge discharged from the sludge discharge outlet of the sludge reduction means. Then, a reduction effect amount is calculated from the calculated sludge reduction amount, and a charge corresponding to the calculated reduction effect amount is charged to the user.

このような方法、装置の構成では、運営者は、ユーザの使用に供した汚泥削減手段での汚泥削減量から削減効果金額を求め、得られた削減効果金額に応じた対価をユーザに請求して汚泥削減手段の運用を図ることができる。特に、汚泥削減量は、前記汚泥削減手段の汚泥投入入口での汚泥投入量の計測値から演算した汚泥投入量と、前記汚泥削減手段の汚泥排出出口での計測値から演算した汚泥排出量と、に基づき演算して求めるので、微生物の活性度の変化など様々な理由による汚水処理施設からの汚泥発生量の変化をも反映させられる。 In such a method and apparatus configuration, the operator obtains a reduction effect amount from the amount of sludge reduction by the sludge reduction means provided for use by the user, and charges the user for compensation according to the obtained reduction effect amount. Therefore, the sludge reduction means can be operated. In particular, the sludge reduction amount is the sludge input amount calculated from the measured value of the sludge input amount at the sludge input port of the sludge reduction means, and the sludge discharge amount calculated from the measured value value of the sludge discharge outlet of the sludge reduction means. Therefore, it is possible to reflect changes in the amount of sludge generated from sewage treatment facilities due to various reasons such as changes in the activity of microorganisms.
上記方法において、さらに、汚泥削減手段は、汚水処理施設から出る汚泥を貯留する汚泥貯留槽と、前記汚泥貯留槽に貯留された汚泥を破砕あるいは可溶化する汚泥破壊装置とで構成されたものを用いることができる。 In the above method, the sludge reduction means further comprises a sludge storage tank for storing sludge from a sewage treatment facility and a sludge destruction device for crushing or solubilizing sludge stored in the sludge storage tank.

In order to operate the reduction means, the sludge reduction amount is calculated based on the sludge input amount measured at the sludge inlet of the sludge reduction means and the sludge discharge amount measured at the sludge outlet, and the activity of microorganisms is calculated. Changes in the amount of sludge generated from sewage treatment facilities due to various reasons such as changes are required to be reflected, and it is always possible to request compensation without excess or deficiency based on the amount of reduction effect based on the actual amount of sludge reduction.

Since the amount of effect can be evaluated accurately, it is always possible to request compensation without excess or deficiency based on the amount of effect of reduction based on the actual amount of sludge reduction, and the economic fairness of users and sludge reduction means operators can be ensured.
上記に加え、さらに、汚水処理施設に追加して設けた汚泥削減手段を前記汚水処理施設利用者に貸与しての運用上、汚泥削減手段の運転管理・メンテナンスを請け負うことで、汚泥削減効果を高め、また安定させられるので、ユーザ側の残留汚泥の処理負荷のさらなる低下、安定を図り、汚泥削減効果金額をさらに高め、また安定させられる。 In addition to the above, in addition to lending the sludge reduction means additionally provided to the sewage treatment facility to the users of the sewage treatment facility, subcontracting the operation management and maintenance of the sludge reduction means, the sludge reduction effect can be obtained. Since it can be increased and stabilized, the processing load of the residual sludge on the user side can be further reduced and stabilized, and the amount of sludge reduction effect can be further increased and stabilized.
上記に加え、さらに、汚泥削減量は汚泥投入量および汚泥排出量の時系列累計データから演算した近似式から求める結果、計測機器の故障によりデータが取れない期間が存在してもそれら近似式の演算が可能で、汚泥削減量の演算、削減効果金額の演算も可能となる。また、汚泥投入量と汚泥排出量との時系列累計データをグラフ表示してそれらの経時的な状況、変化を目視で評価させられるので、汚泥削減手段の稼働状況、つまりその時々の汚泥削減効果、およびその変化がわかり、汚泥削減手段が正常に運転されているか否かを容易に確認できるとともに、使用環境の変化に合わせて運転方法を改善する手助けともなる。 In addition to the above, the amount of sludge reduction is obtained from an approximate expression calculated from time series cumulative data of sludge input and sludge discharge. It is possible to calculate the amount of sludge reduction and the reduction effect amount. In addition, since the time-series cumulative data of sludge input and sludge discharge are displayed in a graph, and the status and changes over time can be visually evaluated, the operating status of sludge reduction means, that is, the sludge reduction effect at that time And the change thereof can be easily confirmed whether or not the sludge reduction means is operating normally, and it also helps to improve the operation method according to the change of the use environment.
上記に加え、さらに、汚泥投入量と汚泥排出量とを時系列累計データの近似式をグラフ表示することで、汚泥削減量をより単純化してわかりやすく表示できるので、汚水処理装置利用者である汚泥削減手段のユーザに納得性のある費用を請求できる。 In addition to the above, the sludge reduction amount can be displayed in a simpler and easier-to-understand manner by displaying the sludge input amount and sludge discharge amount as an approximate expression of the time-series cumulative data. It is possible to charge the user of the sludge reduction means with a satisfactory cost.

設２の利用者をユーザＡとして使用に提供し、汚泥削減手段１の汚泥投入入口３での投入汚泥３２に関する計測値から演算した汚泥投入量Ｓｉ、汚泥削減手段１の汚泥排出出口４での排出汚泥３２ａに関する計測値から演算した汚泥排出量Ｓoと、に基づき汚泥削減量Ｓｘを演算し、演算された汚泥削減量Ｓｘから削減効果金額Ｙ0を演算し、前記演算された削減効果金額Ｙ0に応じた対価Ｙ1を前記ユーザＡに請求する。これにより、運用者Ｂは、ユーザＡの使用に供した汚泥削減手段１での汚泥削減量Ｓｘから削減効果金額Ｙ0を求め、得られた削減効果金額Ｙ0に応じた対価Ｙ1をユーザＡに請求して汚泥削減手段１の運用を図ることができる。特に、汚泥削減量Ｓｘは、汚泥削減手段１の汚泥投入入口３で投入汚泥に関する計測値から演算した汚泥投入量Ｓｉと、汚泥削減手段１の汚泥排出出口４での排出汚泥に関した計測値から演算した汚泥排出量Ｓoと、に基づき演算して求めるので、微生物の活性度の変化など様々な理由により汚水処理施設２からの汚泥発生量の変化をも反映させられる。従って、ユーザＡの使用に供した汚泥削減手段１による汚泥の削減結果から求めた削減効果金額Ｙ0に応じた対価Ｙ1をユーザＡに請求し、汚泥削減手段１の運用を図るのに、汚泥削減量Ｓｘを、汚泥削減手段１の汚泥投入入口３で計測した汚泥投入量と、汚泥排出出口４で計測した汚泥排出量とに基づき演算して、微生物の活性度の変化など様々な理由による汚水処理施設からの汚泥発生量の変化が反映するように求められ、実際の汚泥削減量Ｓｘに基づいた削減効果金額Ｙ0による過不足のない対価Ｙ1の請求が常にでき、ユーザＡ、運用者Ｂの経済的な公平性を確保でき、高い信頼性が得られる。
Referring to the operation device 100 of the sludge reduction means of the present embodiment shown in FIG. 1, the operation method of the sludge reduction means 1 of the present embodiment is the sewage treatment of the sludge reduction means 1 that reduces the sludge after the sewage treatment. The user of the facility 2 is provided for use as the user A, and the sludge input amount Si calculated from the measured value regarding the input sludge 32 at the sludge input 3 of the sludge reduction means 1 and the sludge discharge outlet 4 of the sludge reduction means 1 are used. sludge emissions So computed from the measured values for the discharge sludge 32a, calculates the sludge reduction Sx based on, it calculates the reduction amount Y 0 from the calculated sludge reduction amount Sx, the computed savings amount Y A charge Y 1 corresponding to 0 is charged to the user A. Thereby, the operator B obtains the reduction effect amount Y 0 from the sludge reduction amount Sx in the sludge reduction means 1 provided for the use of the user A, and gives the consideration Y 1 corresponding to the obtained reduction effect amount Y 0 to the user. A can be charged and sludge reduction means 1 can be operated. In particular, the sludge reduction amount Sx is obtained from the sludge input amount Si calculated from the measured value related to the input sludge at the sludge input 3 of the sludge reducing means 1 and the measured value related to the discharged sludge at the sludge discharge outlet 4 of the sludge reducing means 1. Since the calculation is based on the calculated sludge discharge amount So, changes in the amount of sludge generated from the sewage treatment facility 2 can be reflected for various reasons such as changes in the activity of microorganisms. Therefore, in order to charge the user A for the compensation Y 1 according to the reduction effect amount Y 0 obtained from the sludge reduction result by the sludge reduction means 1 used for the user A, and to operate the sludge reduction means 1, The sludge reduction amount Sx is calculated based on the sludge input amount measured at the sludge input port 3 of the sludge reduction means 1 and the sludge discharge amount measured at the sludge discharge port 4 for various reasons such as changes in the activity of microorganisms. It is required to reflect the change in the amount of sludge generated from the sewage treatment facility, and it is always possible to charge the compensation Y 1 without excess or deficiency based on the reduction effect amount Y 0 based on the actual sludge reduction amount Sx. The economic fairness of the operator B can be ensured and high reliability can be obtained.
このような方法を実現するのに、本実施の形態の汚泥削減手段１の運用装置１００としては、少なくとも、ユーザＡの汚水処理場２１に構築された汚水処理施設２から出る汚泥を削減するように設置して汚水施設利用者をユーザＡとして使用に供する既述の汚泥削減手段１に加え、汚泥削減手段１の汚泥投入入口３、つまり汚泥投入入口３側に設けられて汚泥投入量Ｓｉを演算する汚泥投入量演算手段１２と、汚泥削減手段１の汚泥排出出口４、つまり汚泥排出出口４側に設けられて汚泥排出量Ｓoを演算する汚泥排出量演算手段１３と、前記汚泥投入量演算手段１２で演算された汚泥投入量Ｓｉと前記汚泥排出量演算手段１３で演算された汚泥排出量Ｓoから汚泥削減量Ｓｘを演算する汚泥削減量演算手段１４と、この汚泥削減量演算手段１４で演算された汚泥削減量Ｓｘから削減効果金額Ｙ0を演算し、削減効果金額に応じた対価Ｙ1の前記ユーザＡへの請求に供する削減効果演算手段と１５から構成された監視制御装置２２などとして備えたものでよく、少なくとも対価の請求業務を除いて自動的に実現することができる。もっとも、請求業務も双方間に構築した通信システムを通じ自動的に実行することもできる。それには、運用者Ｂは、例えば、運用制御手段２８において、ユーザＡの汚水処理場２１側および監視制御装置２２側の通信手段２３、２４と無線ないしはウエブでのネットワークによる通信を行う通信手段２５、２６を持ち、監視制御装置２２側からの削減効果金額Ｙ0の情報から対価Ｙ1を対価演算装置２７により演算して、ユーザＡに請求するようにできる。 In order to realize such a method, as the operation device 100 of the sludge reduction means 1 of the present embodiment, at least sludge from the sewage treatment facility 2 constructed in the sewage treatment plant 21 of the user A is reduced. In addition to the previously described sludge reduction means 1 for use as a user A by the user of the sewage facility, the sludge input amount Si is provided at the sludge input 3 of the sludge reduction means 1, that is, the sludge input 3 side. The sludge input amount calculating means 12 for calculating, the sludge discharge amount calculating means 13 for calculating the sludge discharge amount So provided on the sludge discharge outlet 4 of the sludge reduction means 1, that is, the sludge discharge outlet 4 side, and the sludge input amount calculation. The sludge reduction amount calculation means 14 for calculating the sludge reduction amount Sx from the sludge input amount Si calculated by the means 12 and the sludge discharge amount So calculated by the sludge discharge amount calculation means 13, and the sludge reduction amount calculation means 1 In calculating the savings amount Y 0 from the calculated sludge reductions Sx, reducing the effects consideration Y 1 corresponding to the amount reduced subjected to bill the user A effect computing means and monitoring control device constructed from 15 22 Etc., and can be automatically realized at least excluding the billing work for the consideration. However, the billing operation can also be automatically executed through a communication system established between the two parties. For example, the operator B, for example, in the operation control means 28, communicates with the communication means 23, 24 on the user A's sewage treatment plant 21 side and the monitoring control apparatus 22 side wirelessly or via a network on the web. , 26, and the consideration Y 1 is calculated from the information of the reduction effect amount Y 0 from the monitoring control device 22 side by the consideration calculation device 27 and charged to the user A.
ここで、監視制御装置２２を構成している汚泥投入量演算手段１２、汚泥排出量演算手段１３、汚泥削減量演算手段１４および削減効果演算手段１５、運用制御手段２８、のそれぞれは、パーソナルコンピュータあるいは、シーケンサなどの電子制御装置のソフトウエアとして実現することができ、削減効果金額Ｙ0は、例えば、次式
Ｙ0（円）＝汚泥処理単価（円／ｋｇ）×汚泥削減量Ｓｘ（ｋｇ）
で算出する。また、対価Ｙ1は、削減効果金額Ｙ0に、これに含まれないその他の諸費用を加算したものとして算出する。
Here, each of the sludge input amount calculating means 12, the sludge discharge amount calculating means 13, the sludge reduction amount calculating means 14, the reduction effect calculating means 15, and the operation control means 28 constituting the monitoring control device 22 is a personal computer. Alternatively, it can be realized as software of an electronic control device such as a sequencer. The reduction effect amount Y 0 is, for example, the following formula: Y 0 (yen) = sludge treatment unit price (yen / kg) × sludge reduction amount Sx (kg )
Calculate with The consideration Y 1 is calculated as the reduction effect amount Y 0 plus other expenses not included therein.
一方、汚泥削減手段１は、例えば、汚水処理施設２から出る汚泥を貯留する汚泥貯留槽１ａと、この汚泥貯留槽１ａに貯留された汚泥を破砕あるいは可溶化する汚泥破壊装置１ｂとで構成されたものを用いるが、そのために、汚水処理施設２が、例えば原水３１を導入して生物処理する生物処理槽２ａにて生物処理した後、沈殿槽２ｂにて沈殿処理し残留した汚泥３２を排出させるものであることに対応して、汚泥貯留槽１ａは沈殿槽２ｂに接
続して排出される汚泥３２を導入して一旦貯留して汚泥破壊装置１ｂによる汚泥破壊に供するようにし、汚泥破壊装置１ｂは汚泥貯留槽１ａから供給される汚泥３２を汚泥破壊処理しながら汚泥貯留槽１ａに戻すことを繰り返すようにしている。これにより、対象とする汚泥３２を汚泥貯留槽１ａに導入して、汚泥破壊装置１ｂでの機械的、化学的、オゾン、バイオ、超音波といった適当な手法による、汚泥の可溶化や破砕に繰り返し供して汚泥微生物の細胞膜、ブロックを破壊し、汚泥３２の量を大幅に削減し、ＶＴＳ（Ｖｏｌａｔｉｌｅ Ｔｏｔａｌ Ｓｏｌｉｄ：揮発性有機酸）の低下による脱水性能の向上などが図れる。従って、対象とする汚泥３２を汚泥貯留槽１ａに導入して、汚泥破壊装置１ｂでの機械的、化学的、オゾン、バイオ、超音波といった適当な手法による汚泥の可溶化や破砕に供することで、汚泥微生物の細胞膜、ブロックを破壊し、汚泥３２の量を大幅に削減し、ＶＴＳの低下による脱水性能の向上などを図って、ユーザＡ側での残留汚泥の処理負荷を低減し、運用者Ｂの請求額を高められる。
On the other hand, the sludge reduction means 1 is comprised by the sludge storage tank 1a which stores the sludge which comes out of the sewage treatment facility 2, and the sludge destruction apparatus 1b which crushes or solubilizes the sludge stored in this sludge storage tank 1a, for example. For this purpose, for example, the sewage treatment facility 2 performs biological treatment in the biological treatment tank 2a in which raw water 31 is introduced and biologically treated, and then precipitates in the sedimentation tank 2b and discharges the remaining sludge 32. Correspondingly, the sludge storage tank 1a is connected to the sedimentation tank 2b, introduces the sludge 32 discharged and temporarily stores it for sludge destruction by the sludge destruction apparatus 1b. 1b repeats returning sludge 32 supplied from sludge storage tank 1a to sludge storage tank 1a while carrying out sludge destruction processing. As a result, the target sludge 32 is introduced into the sludge storage tank 1a, and it is repeatedly solubilized and crushed by an appropriate method such as mechanical, chemical, ozone, bio, and ultrasonic in the sludge destruction apparatus 1b. It can be used to destroy cell membranes and blocks of sludge microorganisms, greatly reduce the amount of sludge 32, and improve dehydration performance by lowering VTS (Volatile Total Solid: volatile organic acid). Therefore, by introducing the target sludge 32 into the sludge storage tank 1a and subjecting it to sludge solubilization and crushing by a suitable method such as mechanical, chemical, ozone, bio, and ultrasonic in the sludge destruction device 1b. , Destroying sludge microbial cell membranes and blocks, drastically reducing the amount of sludge 32, improving dewatering performance by lowering VTS, reducing the residual sludge treatment load on the user A side, B's charge can be increased.
また、汚泥投入量演算手段１２は、汚泥削減手段１の汚泥投入入口３にて、投入汚泥３２の流量計３３により計測する流量Ｑ1と、投入汚泥３２のＳＳ計（透視度計）３４により計測する濃度Ｄ1と、の積にて汚泥投入量Ｓｉを演算し、汚泥排出量演算手段１３は、汚泥削減手段１の汚泥排出出口４にて、排出汚泥３２ａの流量計３５により計測する流量Ｑ2と、排出汚泥のＳＳ計３６により計測する濃度Ｄ2と、の積にて汚泥排出量Ｓoを演算するようにしている。ＳＳ計３４、３６は透視度方式にて汚泥濃度ＭＬＳＳを連続計測できるので、流量計により連続に計速する流量との積として、その時々の実投入汚泥量、実排出汚泥量が正確に得られ、汚泥削減効果金額を的確に評価することができる。従って、連続計測したＳＳ計３４、３６による汚泥濃度Ｄ1、Ｄ2と、流量計３３、３５による流量Ｑ1、Ｑ2との積により、その時々の正確な実投入汚泥量Ｓｉ、実排出汚泥量Ｓoを容易かつ低コストに得て、汚泥削減効果金額Ｙ0を的確に評価できるので、実際の汚泥削減量Ｓｘに基づいた削減効果金額Ｙ0による過不足のない対価Ｙ1の請求が常にでき、ユーザＡ、運用者Ｂの経済的な公平性を確保でき、相互の信頼性を高められる。なお、ＳＳ計はＭＬＳＳ計（汚泥濃度計）で代替してもよい。 Also, the sludge input amount calculation means 12 includes a flow rate Q 1 measured by the flow meter 33 of the input sludge 32 and an SS meter (permeability meter) 34 of the input sludge 32 at the sludge input inlet 3 of the sludge reduction means 1. The sludge input amount Si is calculated by the product of the measured concentration D 1, and the sludge discharge amount calculation means 13 is the flow rate measured by the flow meter 35 of the discharged sludge 32 a at the sludge discharge outlet 4 of the sludge reduction means 1. The sludge discharge amount So is calculated by the product of Q 2 and the concentration D 2 measured by the SS meter 36 of the discharged sludge. The SS meters 34 and 36 can continuously measure the sludge concentration MLSS using the transparency method, so the actual amount of sludge that is actually input and the amount of sludge that is actually discharged can be obtained accurately as the product of the flow rate continuously measured by the flow meter. The amount of sludge reduction effect can be evaluated accurately. Therefore, the product of the sludge concentration D 1 , D 2 by the SS meters 34, 36 continuously measured and the flow rates Q 1 , Q 2 by the flow meters 33, 35 gives the actual actual input sludge amount Si, actual discharge at that time. Since the sludge amount So can be obtained easily and at low cost and the sludge reduction effect amount Y 0 can be accurately evaluated, the compensation Y 1 can be charged without excess or deficiency by the reduction effect amount Y 0 based on the actual sludge reduction amount Sx. It is always possible to secure the economic fairness of the user A and the operator B, and the mutual reliability can be improved. The SS meter may be replaced with an MLSS meter (sludge concentration meter).
さらに、汚水処理施設２に追加して設けた汚泥削減手段１を前記汚水処理施設２の利用者をユーザＡとして貸与するのに、汚泥削減手段１の運転管理・メンテナンスを請け負い、削減効果金額Ｙ0に応じた対価Ｙ1を前記汚水処理施設利用者であるユーザＡに請求するようにもできる。これにより、汚水処理施設２に追加して設けた汚泥削減手段１を前記汚水処理施設利用者であるユーザＡに貸与して、削減効果金額Ｙ0に応じた対価Ｙ1をユーザＡに請求するのに、汚泥削減手段１の運転管理・メンテナンスを請け負うことで、汚泥削減効果を高め、また安定させて汚泥削減装置の運用が図れる。従って、汚水処理施設２に追加して設けた汚泥削減手段１を汚水処理施設利用者であるユーザＡに貸与しての運用上、汚泥削減手段１の運転管理・メンテナンスを請け負うことで、汚泥削減効果を高め、また安定させられるので、ユーザＡ側の最終的な排出汚泥３２ａの処理負荷のさらなる低下、安定を図り、汚泥削減効果金額Ｙ0をさらに高め、また安定させられる。 Furthermore, in order to lend the sludge reduction means 1 provided in addition to the sewage treatment facility 2 as a user A as a user A, the sludge reduction means 1 is contracted for operation management and maintenance, and the reduction effect amount Y It is also possible to charge the user A who is a user of the sewage treatment facility for the consideration Y 1 corresponding to 0 . As a result, the sludge reduction means 1 additionally provided in the sewage treatment facility 2 is lent to the user A who is the user of the sewage treatment facility, and the user A is charged the consideration Y 1 corresponding to the reduction effect amount Y 0. However, by subcontracting the operation management / maintenance of the sludge reduction means 1, the sludge reduction effect can be improved and the sludge reduction apparatus can be operated stably. Therefore, the sludge reduction means 1 provided in addition to the sewage treatment facility 2 is loaned to the user A who is the user of the sewage treatment facility, and the operation management / maintenance of the sludge reduction means 1 is contracted to reduce sludge. enhance the effect, and because be stabilized, further reduction in the processing load of the final discharge sludge 32a of the user a side, ensures stable, further enhances the sludge reduction amount Y 0, also be stabilized.
また、一定期間の汚泥投入量Ｓｉおよび一定期間の汚泥排出量Ｓoを時系列に記憶し、この記憶した記憶データを時系列累計データに変換し、その近似式ＳｉＸ、ＳｏＸを最小二乗法で演算し、前記時系列累計データと前記近似式ＳｉＸ、ＳｏＸグラフ表示するようにできる。それには、一定期間の汚泥投入量Ｓｉを時系列に記憶する汚泥投入量記憶手段４１、および一定期間の汚泥排出量Ｓoを時系列に記憶する汚泥排出量記憶手段４２を備え、これら記憶手段４１、４２の記憶データを時系列累計データＡＳｉ、ＡＳoに変換し、それらの近似式ＳｉＸ、ＳoＸを演算する演算手段として汚泥削減量演算手段１４が機能し、前記時系列累計データＡＳｉ、ＡＳoと前記近似式ＳｉＸ、ＳoＸをグラフ表示する表示手段４３を備えたものとしている。これにより、削減効果金額Ｙ0を演算するもととなる汚泥削減量Ｓｘは、汚泥投入量Ｓｉおよび汚泥排出量Ｓoの時系列累計データＡＳｉ
、ＡＳoから演算した近似式ＳｉＸ、ＳoＸから演算するので、流量計３３、３５やＳＳ計３４、３６などの計測機器の故障によりデータが取れない期間が存在しても近似式ＳｉＸ、ＳoＸでの演算が可能となり、汚泥削減量Ｓｘの演算、削減効果金額Ｙ0の演算も可能となる。また、汚泥投入量Ｓｉと汚泥排出量Ｓoとの時系列累計データＡＳｉ、ＡＳoをグラフ表示して、それらの経時的な状況、変化を目視で評価させられるので、汚泥削減手段１の稼働状況、つまりその時々の汚泥削減効果、およびその変化がわかり、汚泥削減手段１が正常に運転されているか否かを容易に確認できるとともに、使用環境の変化に合わせて運転方法を改善する手助けともなる。
Also, the sludge input amount Si for a certain period and the sludge discharge amount So for a certain period are stored in time series, and the stored data is converted into time series cumulative data, and the approximate expressions SiX and SoX are calculated by the least square method. The time series cumulative data and the approximate expression SiX, SoX graph can be displayed. For this purpose, a sludge input amount storage means 41 for storing the sludge input amount Si for a certain period in time series and a sludge discharge amount storage means 42 for storing the sludge discharge amount So for a predetermined period in time series are provided. , 42 is converted into time-series accumulated data ASi, ASo, and sludge reduction amount calculating means 14 functions as a calculating means for calculating their approximate expressions SiX, SoX, and the time-series accumulated data ASi, ASo and the above-mentioned It is assumed that a display means 43 for displaying the approximate expressions SiX and SoX in a graph is provided. Thus, the sludge reduction amount Sx from which the reduction effect amount Y 0 is calculated is the time series cumulative data ASi of the sludge input amount Si and the sludge discharge amount So.
Since the calculation is performed from the approximate expressions SiX and SoX calculated from ASo, even if there is a period during which data cannot be obtained due to a failure of the measuring device such as the flowmeters 33 and 35 and the SS meters 34 and 36, the approximate expressions SiX and SoX It is possible to calculate the sludge reduction amount Sx and the reduction effect amount Y 0 . In addition, the time-series cumulative data ASi, ASo of the sludge input amount Si and the sludge discharge amount So are displayed in a graph, and the time-dependent situation and change thereof can be visually evaluated. That is, the sludge reduction effect and the change at that time can be known, and it can be easily confirmed whether or not the sludge reduction means 1 is normally operated, and it also helps to improve the operation method in accordance with the change in the use environment.
なお、汚泥削減量演算手段１４は、汚泥削減量Ｓｘを汚泥投入量Ｓｉの時系列近似式ＳｉＸと汚泥排出量Ｓoの時系列近似式ＳoＸから演算するようにできる。これにより、汚泥投入量Ｓｉと汚泥排出量Ｓoとを時系列累計データＡＳｉ、ＡＳoの近似式ＳｉＸ、ＳoＸをグラフ表示することで、汚泥削減量Ｓｘをより単純化して目視比較評価に供することができる。このように、汚泥投入量Ｓｉと汚泥排出量Ｓoとを時系列累計データＡＳｉ、ＡＳoの近似式ＳｉＸ、ＳoＸをグラフ表示することで、汚泥削減量Ｓｘをより単純化してわかりやすく表示できるので、汚水処理施設２の利用者である汚泥削減手段１のユーザＡに納得性のある費用を請求できる。 The sludge reduction amount calculating means 14 can calculate the sludge reduction amount Sx from the time series approximate expression SiX of the sludge input amount Si and the time series approximate expression SoX of the sludge discharge amount So. Thus, by displaying the sludge input amount Si and the sludge discharge amount So as a graph of the approximate expressions SiX and SoX of the time series cumulative data ASi and ASo, the sludge reduction amount Sx can be further simplified and used for visual comparison evaluation. it can. Thus, by displaying the sludge input amount Si and the sludge discharge amount So in the time series cumulative data ASi, approximate expressions SiX, SoX of the Aso, the sludge reduction amount Sx can be displayed more simply and easily. The user A of the sludge reduction means 1 who is a user of the sewage treatment facility 2 can be charged with a reasonable cost.
最後に、汚水処理施設２から汚泥削減手段１、より具体的には沈殿槽２ｂから汚泥貯留槽１ａへの汚泥の投入は、汚泥投入入口３での流量計３３、ＳＳ計３４の設置位置の上流に設けた汚泥投入弁４４を開くことで行い、閉じることで汚泥の投入を停止して、汚水処理施設２から汚泥削減手段１への投入を制御し、定量ずつ汚泥削減処理できるようにしている。これに伴い、汚泥削減手段１、より具体的には汚泥貯留槽１ａからの削減処理後の汚泥の排出は、汚泥排出出口４での流量計３５、ＳＳ計３６の設置位置の上流に設けた汚泥排出弁４５を開くことで行い、閉じることで排出汚泥３２ａの排出を停止し、汚泥削減の処理時間の制御などを行う。これら汚泥投入弁４４、汚泥排出弁４５の適時的な開閉によって汚泥削減手段１での汚泥削減の単位処理量、処理時間を適宜に設定できる。これらの制御のために、汚泥投入弁４４、汚泥排出弁４５のそれぞれは、汚泥投入弁開閉手段４６、汚泥排出弁開閉手段４７によって個別に開閉制御されるようにしている。また、汚泥投入弁４４および汚泥排出弁４５の下流直ぐの位置に洗浄弁５１、５２を通じて水道水を供給して洗浄する洗浄手段５３、５４が接続され、汚泥投入弁４４、汚泥排出弁４５が閉じ状態にあるときに洗浄弁５１、５２を開いて水道水を供給することで流量計３３、３５、ＳＳ計３４、３６を洗浄する。これによって、流量計３３、３５、ＳＳ計３４、３６は長期に亘って正確な計測ができる。また、汚泥貯留槽１ａからの排出汚泥３２ａは脱水機５５により脱水処理してから最終処分する。 Finally, the sludge reduction means 1 from the sewage treatment facility 2, more specifically, the sludge input from the sedimentation tank 2 b to the sludge storage tank 1 a is performed at the installation position of the flow meter 33 and the SS meter 34 at the sludge inlet 3. This is done by opening the sludge injection valve 44 provided upstream, and closing it to stop the introduction of sludge, and controlling the introduction of sludge from the sewage treatment facility 2 to the sludge reduction means 1 so that the sludge reduction treatment can be performed quantitatively. Yes. Accordingly, sludge discharge after the reduction treatment from the sludge reduction means 1, more specifically, the sludge storage tank 1a, is provided upstream of the installation position of the flow meter 35 and the SS meter 36 at the sludge discharge outlet 4. The sludge discharge valve 45 is opened and closed, and the discharge of the discharged sludge 32a is stopped, and the processing time for sludge reduction is controlled. By appropriately opening and closing the sludge input valve 44 and the sludge discharge valve 45, the unit treatment amount and treatment time for sludge reduction in the sludge reduction means 1 can be set as appropriate. For these controls, the sludge input valve 44 and the sludge discharge valve 45 are individually controlled to be opened and closed by the sludge input valve opening / closing means 46 and the sludge discharge valve opening / closing means 47. Further, cleaning means 53 and 54 for supplying and cleaning tap water through cleaning valves 51 and 52 are connected to positions immediately downstream of the sludge input valve 44 and the sludge discharge valve 45, and the sludge input valve 44 and the sludge discharge valve 45 are connected to each other. When in the closed state, the flow valves 33 and 35 and the SS meters 34 and 36 are cleaned by opening the cleaning valves 51 and 52 and supplying tap water. Accordingly, the flow meters 33 and 35 and the SS meters 34 and 36 can perform accurate measurement over a long period of time. Also, the discharged sludge 32a from the sludge storage tank 1a is dehydrated by the dehydrator 55 and then finally disposed.
１日単位での汚泥投入と汚泥排出の開始、終了の時間制御は、例えば既述の監視制御装置２２での必要事項を設定し制御する設定手段６０による２４時間タイマー機能を利用した時間設定と計時に基づいて既述の汚泥投入弁開閉手段４６、汚泥排出弁開閉手段４７を制御することにより、予め設定した汚泥投入に関する開始、終了の各時刻に汚泥投入弁４４を開、閉して汚泥投入の開始および終了が行え、その後の予め設定した汚泥排出弁４７を開、閉して汚泥排出の開始、終了の各時刻に汚泥排出の開始および終了が行える。 The time control of the start and end of sludge input and sludge discharge in units of one day is, for example, a time setting using a 24-hour timer function by the setting means 60 for setting and controlling necessary items in the monitoring control device 22 described above. By controlling the above-described sludge input valve opening / closing means 46 and sludge discharge valve opening / closing means 47 based on the timekeeping, the sludge input valve 44 is opened and closed at each of the start time and the end time related to the input of the sludge. The injection can be started and ended, and the sludge discharge valve 47 set in advance thereafter is opened and closed to start and end the sludge discharge at each time of the start and end of the sludge discharge.
図２では、１日単位で２回の汚泥削減処理を行う設定時刻の表示例を示している。図２は設定制御手段６０による既述の表示手段４３を共用した、または設定制御手段６０に付帯する専用の時刻設定画面例であるが、汚泥投入の開始時刻および終了時刻の双方を合わせ「汚泥投入時刻」と表示し、汚泥排出の開始時刻および終了時刻の双方を合わせ「汚泥排出時刻」と表示している。これに対応して、「汚泥投入時刻」表示行でのＯＮ表示列の表示時刻が汚泥投入弁４４の「開」に対応した汚泥投入の「開始時刻」、ＯＦＦ表示列の
表示時刻が汚泥投入弁４４の「閉」に対応した汚泥投入の「終了時刻」としている。また、「汚泥排出時刻」表示行でのＯＮ表示列の表示時刻が汚泥排出弁４５の「開」に対応した汚泥投排出の「開始時刻」、ＯＦＦ表示列の表示時刻が汚泥排出弁４５の「閉」に対応する汚泥排出の「終了時刻」となるようにしている。また、これらの汚泥投入の開始、終了と、汚泥排出の開始、終了とに関する設定時刻は、１日の内での一回目、二回目として表示している。そして、これら表示時刻の設定は、既述の監視制御装置２２に設けた各種の設定を行う図示しない対応する位置に設定時刻を表示し、ＯＦＦ表示に対応して汚泥投入開始時刻を表示している。そこで、これら時刻の設定は対応する行および列の交差升への設定時刻入力操作として行われる。
In FIG. 2, the example of a display of the setting time which performs the sludge reduction process twice per day is shown. FIG. 2 is an example of a dedicated time setting screen that shares the above-described display means 43 by the setting control means 60 or is attached to the setting control means 60. The “sludge discharge time” is displayed together with the start time and end time of the sludge discharge. Correspondingly, the display time of the ON display column in the “sludge input time” display row is the “start time” of the sludge input corresponding to “open” of the sludge input valve 44, and the display time of the OFF display column is the sludge input. The “end time” of the sludge input corresponding to the “closing” of the valve 44 is set. In addition, the display time of the ON display column in the “sludge discharge time” display row is the “start time” of sludge throwing / discharging corresponding to “open” of the sludge discharge valve 45, and the display time of the OFF display column is the sludge discharge valve 45 The “end time” of sludge discharge corresponding to “closed” is set. In addition, the set times regarding the start and end of the sludge input and the start and end of the sludge discharge are displayed as the first and second times in the day. The display time is set by displaying the set time at a corresponding position (not shown) for performing various settings provided in the monitoring control device 22 described above, and displaying the sludge charging start time corresponding to the OFF display. Yes. Therefore, these time settings are performed as a set time input operation to the intersection of the corresponding row and column.
このような時刻設定に従って進行する汚泥削減処理において、汚泥削減量演算のために、まず、図３に示すように、処理の進行に伴い汚泥投入量記憶手段４１に記憶されていく汚泥投入量Ｓｉと、処理の進行に伴い汚泥排出量記憶手段４２に記憶されていく汚泥排出量Ｓｏと、をそれぞれ時系列累計データＡＳｉ、ＡＳｏとして積算していく。 In the sludge reduction process that proceeds according to such time setting, for the sludge reduction amount calculation, first, as shown in FIG. 3, the sludge input amount Si that is stored in the sludge input amount storage means 41 as the process proceeds. Then, the sludge discharge amount So stored in the sludge discharge amount storage means 42 as the process proceeds is integrated as time-series cumulative data ASi and ASo, respectively.
次いで、時系列累計データＡＳｉ、ＡＳｏ間の、汚泥削減量Ｓｘの評価最終時点の偏差、例えば、対価請求単位期間の末日、さらに具体的には、図３に示す大の月では３１日となる各月の末日に対応する時点の偏差から、汚泥削減量Ｓｘを演算し、削減効果金額Ｙ0、対価Ｙ1を求めユーザＡに課金する。すなわち、汚泥削減量Ｓｘは同時点での汚泥投入および汚泥排出に関する時系列データＡＳｉ、ＡＳｏの差分、ＡＳｉ−ＡＳｏで求められる。なお、最初の３日間は実績を取得できなかったため、汚泥の投入量も排出量もゼロと記録したものである。 Next, the deviation at the final evaluation point of the sludge reduction amount Sx between the time series cumulative data ASi and ASo, for example, the last day of the consideration unit period, more specifically, 31 days in the large month shown in FIG. The sludge reduction amount Sx is calculated from the deviation at the time corresponding to the last day of each month, and the reduction effect amount Y 0 and the consideration Y 1 are obtained and charged to the user A. That is, the sludge reduction amount Sx is obtained by the difference between the time series data ASi and ASo relating to sludge input and sludge discharge at the same point, ASi-ASo. In addition, since the results could not be acquired for the first three days, the amount of sludge input and discharge was recorded as zero.
実施例１の場合のように、汚泥投入量記憶手段４１に記憶されていく汚泥投入量を処理日数分の時系列累計データＡＳｉとして図４（ａ）に示すようにプロットし、最小二乗法で近似式ＳｉＸを演算するのに併せ、処理の進行に伴い汚泥排出量記憶手段４２に記憶されていく汚泥排出量を処理日数分の時系列累計データＡＳｏとして図４（ｂ）に示すようにプロットし、最小二乗法で近似式ＳｏＸを演算する。これら近似式ＳｉＸ、ＳｏＸは、必要なら図３に示す処理開始日から実績の取れなかった３日間側にも延長させて推定することができる。 As in the first embodiment, the sludge input amount stored in the sludge input amount storage means 41 is plotted as time series cumulative data ASi for the number of processing days as shown in FIG. In addition to calculating the approximate expression SiX, the sludge discharge amount stored in the sludge discharge amount storage means 42 as the process proceeds is plotted as time-series cumulative data ASo for the number of processing days as shown in FIG. Then, the approximate expression SoX is calculated by the least square method. These approximate formulas SiX and SoX can be estimated by extending to the three-day side that has not been obtained from the processing start date shown in FIG. 3 if necessary.
次いで、これら２つの近似式ＳｉＸ、ＳｏＸ間の、汚泥削減量Ｓｘの評価最終時点の差、例えば、対価請求単位期間の末日、さらに具体的には、図３に示す大の月では３１日などとなる各月の末日に対応する時点の差から、汚泥削減量Ｓｘを演算し、削減効果金額Ｙ0、対価Ｙ1を求めユーザＡに課金する。 Next, the difference in the final evaluation point of the sludge reduction amount Sx between these two approximate formulas SiX and SoX, for example, the last day of the billing unit period, more specifically, 31 days in the large month shown in FIG. The sludge reduction amount Sx is calculated from the difference in time corresponding to the last day of each month, and the reduction effect amount Y 0 and the consideration Y 1 are obtained and charged to the user A.
これに併せ、前記汚泥投入量Ｓｉの時系列累計データＡＳｉおよび汚泥排出量Ｓｏの時系列累計データＡＳｏを図４に示すようなグラフとして表示手段４３に表示して、それら汚泥投入量Ｓｉ、汚泥排出量Ｓｏ、それらの偏差Ｓｘに関する経時的な状況、変化の目視評価に供する。 At the same time, the time series cumulative data ASi of the sludge input amount Si and the time series cumulative data ASo of the sludge discharge amount So are displayed on the display means 43 as a graph as shown in FIG. It is used for the visual evaluation of the amount of discharge So, the situation over time regarding the deviation Sx, and the change.
本実施例３は、時系列累計データＡＳｉ、ＡＳｏが、図５（ａ）に示すように、実施例２の場合のように図３に示す処理開始日から実績の取れなかった３日間に加え、計測器の故障によってデータの取れなかった途中の６日間を含め、対価請求期間としてのある大の月の３１日間中２２日しかデータが取れなかった場合の対応例を示している。 In the third embodiment, the time-series cumulative data ASi and ASo are added to the three days in which the results were not obtained from the processing start date shown in FIG. 3 as in the second embodiment, as shown in FIG. In this example, data is obtained only for 22 days in 31 days of a certain large month as a billing period, including 6 days during which data could not be obtained due to a failure of the measuring instrument.
この場合も、図５（ｂ）に示すように、取得している時系列累計データＡＳｉ、ＡＳoとしてプロットしたデータから近似式ＳｉＸ、ＳoＸを求め、得られた近似式ＳｉＸ、Ｓo
Ｘからデータ取得できなかった日の汚泥投入量Ｓｉおよび汚泥排出量Ｓｏを演算することができる。従って、仮に、図５（ｂ）に示すように、汚泥削減量Ｓｘを算出する汚泥削減量Ｓｘの評価最終時点でのデータ取りができていなくても、近似式ＳｉＸ、ＳoＸから演算することができる。
Also in this case, as shown in FIG. 5B, approximate expressions SiX and SoX are obtained from the data plotted as the acquired time series cumulative data ASi and ASo, and the obtained approximate expressions SiX and SoX are obtained.
The sludge input amount Si and sludge discharge amount So on the day when data could not be acquired from X can be calculated. Accordingly, as shown in FIG. 5 (b), even if the data at the final evaluation point of the sludge reduction amount Sx for calculating the sludge reduction amount Sx is not obtained, the calculation can be performed from the approximate expressions SiX and SoX. it can.
