| description | To provide a flocculant injection controller capable of controlling a flocculant injection rate to a more suitable rate, a flocculant injection control method, and a flocculant injection system.SOLUTION: A flocculant injection controller of an embodiment makes a control input of a flocculant injection rate for treatment object water to controls the flocculant injection rate in a flocculant injection control system the controlled variable of which is a flock charging state in the treatment object water changing in accordance with the controlled variable. The flocculant injection controller has a target value calculation part and an injection rate control part. The target value calculation part calculates a target value of the charging state. The injection rate control part controls, on the basis of the target value of the flock charging state calculated by the target value calculation part, the flocculant injection rate so that the flock charging state in the treatment object water may approximate the target value.SELECTED DRAWING: Figure 1
【課題】凝集剤の注入量をより適切な量に制御することができる凝集剤注入制御装置、凝集剤注入制御方法及び凝集剤注入制御システムを提供することである。【解決手段】実施形態の凝集剤注入制御装置は、被処理水に対する凝集剤注入量を操作量とし、前記操作量に応じて変化する前記被処理水中のフロックの荷電状態を制御量とする凝集剤注入制御システムにおいて前記凝集剤注入量を制御する。凝集剤注入制御装置は、目標値算出部と、注入量制御部と、を持つ。目標値算出部は、前記荷電状態の目標値を算出する。注入量制御部は、前記目標値算出部によって算出されたフロックの荷電状態の目標値に基づいて、前記被処理水中のフロックの荷電状態が、前記目標値に近づくように前記凝集剤注入量を制御する。【選択図】図１ |
