Description
これに対して表面電荷が中和しているフロックは電場の影響を受けない。そのため、表面電荷が中和しているフロックの移動方向は、電圧が印加されている状況においても一定ではない。従って個々のフロックの電気泳動速度のばらつきが大きくなり、電気泳動速度の分散値が大きくなる。そのため、表面電荷が中和しているフロックの電気泳動速度の分散値は所定値以上になると考えられる。そこで、この所定値を閾値として、フロックの電気泳動速度の分散値と比較することによって、フロックの表面電荷が中和しているか否かを把握することができる。 On the other hand, flocs whose surface charge is neutralized are not affected by the electric field. Therefore, the moving direction of the flocs whose surface charges are neutralized is not constant even when a voltage is applied. Therefore, the variation in the electrophoresis speed of each floc becomes large, and the dispersion value of the electrophoresis speed becomes large. Therefore, it is considered that the dispersion value of the electrophoresis rate of the flocs whose surface charges are neutralized becomes a predetermined value or more. Therefore, by using this predetermined value as a threshold value and comparing it with the dispersion value of the electrophoresis speed of flocs, it is possible to grasp whether or not the surface charge of flocs is neutralized.
速度測定部９３は、セルＣを通過する混和水が撮像された画像に対してソフトウェアによる画像解析処理を施すことにより画像内のフロックを検出し、検出した個々のフロックの電気泳動速度を求める。電気泳動速度は、連続して撮像された画像間におけるフロックの位置と、撮像周期とに基づいて求められる。速度測定部９３は、検出したフロックごとに電気泳動速度を測定し、各フロックの電気泳動速度の平均値（以下「平均電気泳動速度」という。）を算出する。 The speed measuring unit 93 detects the flocs in the image by performing image analysis processing by software on the image in which the mixed water passing through the cell C is captured, and obtains the electrophoresis speed of each detected flocs. The electrophoresis rate is determined based on the position of flocs between continuously captured images and the imaging period. The speed measuring unit 93 measures the electrophoresis speed for each detected floc and calculates the average value of the electrophoresis speed of each floc (hereinafter referred to as “average electrophoresis speed ”).
なお、速度測定部９３は、各フロックについて求めた電気泳動速度の移動平均をとり、各フロックの移動平均値を平均した値を平均電気泳動速度として算出してもよい。速度測定部９３は、このように算出した平均電気泳動速度の時系列データを凝集状態指標値としてパラメータ同定部１２１に出力する。なお、平均電気泳動速度は、各フロックの電気泳動速度の平均的な値を示すものであれば平均値に限らず他の統計値に置き換えられてもよい。 The speed measuring unit 93 may take the moving average of the electrophoresis speeds obtained for each floc and calculate the average value of the moving averages of the flocs as the average electrophoretic velocity . The velocity measuring unit 93 outputs the time-series data of the average electrophoresis velocity calculated in this way to the parameter identification unit 121 as an agglutination state index value. The average electrophoresis speed is not limited to the average value as long as it indicates the average value of the electrophoresis speed of each floc, and may be replaced with other statistical values.
このように構成された第２の実施形態の水処理プラント１００ａは、画像解析処理によってフロックの平均電気泳動速度を測定する解析部９を備えることにより、凝集剤注入制御装置１に対してより正確な凝集状態指標値を供給することができる。 The water treatment plant 100a of the second embodiment configured in this way is more accurate than the flocculant injection control device 1 by providing an analysis unit 9 for measuring the average electrophoresis speed of flocs by image analysis processing. It is possible to supply an index value of agglomeration state.
