To provide a water treatment system that accurately calculates an appropriate injection rate of powdered activated carbon for removing musty-smelling substances from raw water and uses an appropriate amount of powdered activated carbon.SOLUTION: A water treatment system includes a water treatment facility 10 and a control unit 20 for controlling the water treatment facility. The water treatment system also includes an odor sensor 1 that measures odors caused by odorous substance contained in raw water, a water quality sensor 3 that measures water quality data of raw water, an event data input unit 5 that inputs various data related to events that affect the mold odor, and an external data input unit 4 for the input of external data including weather-related data affecting the mold odor. The control unit 20 calculates the activated carbon injection rate necessary to reduce the mold odor substance to a predetermined reference value or less based on the odor, the water quality data, the external data, and the event data.SELECTED DRAWING: Figure 1 【課題】原水中のカビ臭物質を除去するための粉末活性炭の適正な注入率を精度よく計算し、粉末活性炭の使用量を適切なものとする。【解決手段】水処理システムは、水処理設備１０と、水処理設備を制御するための制御部２０とを備えている。また、この水処理システムは、原水に含まれる臭気物質による臭気を計測する臭気センサ１と、前記原水の水質データを計測する水質センサ３と、カビ臭に影響を与えるイベントに関係する各種データを入力するイベントデータ入力部５と、前記カビ臭に影響を与える気象関連のデータを含む外部データ入力部４とを有する。そして、制御部２０は、前記臭気、前記水質データ、前記外部データ、前記イベントデータに基づき、所定の基準値以下にカビ臭物質を低減するために必要な活性炭注入率を演算する。【選択図】図１
