Zusammenfassung:	To eliminate abnormal data included in time-series data from a plurality of sensors at a water treatment site.SOLUTION: In an effluent quality prediction device (100), a pre-processing unit (103a) performs filtering to a learning dataset, which is a portion of learning data for a first prescribed time in learning data. A model generation unit (103c) generates a prediction model for predicting effluent quality data a prescribed time after the learning dataset. Meanwhile, an effluent quality prediction unit (105) applies the prediction model to the latest data stored in a latest data database (104) and predicts effluent quality data.SELECTED DRAWING: Figure 1 【課題】水処理場の複数のセンサからの時系列データに含まれる異常データを除去する。【解決手段】放流水質予測装置（１００）において、前処理部（１０３ａ）は、学習データの中の第１の所定時間分の学習データを学習データセットとし、学習データセットにフィルタ処理を行う。モデル生成部（１０３ｃ）は、学習データセットから所定時間後の放流水質データを予測するための予測モデルを生成する。また、放流水質予測部（１０５）は、直近データデータベース（１０４）に記憶される直近データに、予測モデルを適用して放流水質データを予測する。【選択図】図１
