MAINTENANCE MANAGEMENT SUPPORT DEVICE FOR WATER SERVICE AND MAINTENANCE MANAGEMENT SUPPORT SYSTEM FOR WATER SERVICE
To provide the maintenance management support device for a water service and the maintenance management support system for a water service, that can maintain treated water quality even if restart of various equipment installed in a water purification treatment facility in a water supply facility occurs or even if a change in an operating condition occurs due to sudden increment in water demand.SOLUTION: The maintenance management support device 7 comprises: an operation plan database that stores an operation plan including an operation condition of a water purification treatment facility 4 that can cause variations in treatment flow rate, a process/water quality database for storing a water quality measurement result at the water purification treatment facility 4, a water purification treatment facility state evaluation unit for determining an amount of sludge accumulated in a sedimentation basin 13 based on the water quality measurement result, a water treatment quality prediction unit that determines the concentration of the settled sludge to be rolled up in the settling basin and calculates turbidity of precipitated treated water based on the turbidity of raw water, a quantity of water intake of the raw water contained in the operation plan, an amount of sludge accumulated in a sedimentation basin, and an injection amount of chemicals containing a coagulant, and an operating condition setting unit for correcting the injection amount of the chemicals or the operation plan based on the turbidity of the precipitation treated water to output to the water purification treatment facility.SELECTED DRAWING: Figure 1
【課題】水道施設内の浄水処理施設に設置される各種機器の再起動又は水需要の急激な増加による運転条件の変化が生じた場合であっても、処理水質を維持可能とする水道の維持管理支援装置及び水道の維持管理支援システムを提供する。【解決手段】水道の維持管理支援装置７は、処理流量の変動が生じ得る浄水処理施設４の運転条件を含む運転計画を格納する運転計画データベース、浄水処理施設４における水質計測結果を格納するプロセス・水質データベース、水質計測結果に基づき沈殿池１３内に蓄積する汚泥量を求める浄水処理施設状態評価部、原水の濁度、運転計画に含まれる原水の取水量、沈殿池内に蓄積する汚泥量、及び凝集剤を含む薬品の注入量に基づき、沈殿池内の沈殿汚泥の巻き上げ濃度を求め沈殿処理水濁度を算出する浄水水質予測部、及び、沈殿処理水濁度に基づき薬品の注入量又は運転計画を修正し浄水処理施設へ出力する運転条件設定部を備える。【選択図】図１
