Description
相対蛍光強度(QSU) 水質 運転管理
0〜5 良 2〜4ヶ月の間に薬品洗浄
5〜10 可 1〜2ヶ月の間に薬品洗浄
10〜20 要監視 1〜4週間の間に薬品洗浄
20超 不可 1週間以内に薬品洗浄
A工場,B工場及びC工場から排出される生物処理水を用い、ポリアミド製逆浸透膜(日東電工社製「ES−20フラットシート」)に以下の条件で通水して、膜濾過流束を測定した。
水温:25℃
操作圧力:0.5〜0.75MPa
回収率:75%
通水時間と膜濾過流束との関係を図1に示す。
上記のA工場,B工場及びC工場からの生物処理水の一部を採取し、以下の条件で蛍光分析を行った。
装置:日立製F−4500型 蛍光分光光度計
ホトマル電圧:700V
スリット:5nm(励起光及び蛍光)
スキャンスピード:12000nm/分
表2のNO.3〜5は、照射する励起波長を275nmとし、検出する蛍光波長を変化させたものである。
表3のNO.6〜8は、検出する蛍光波長を300nmとし、照射する励起波長を変化させたものである。
図1より、C工場,B工場及びA工場の順で、膜濾過流束の低下が大きいことが分かる。
