Analysis of the Chromophoic Dissolved Organic Matter in Process Water by EEMs and PARAFAC
下水、工場排水処理施設において各工程の有機物濃度を監視することは維持管理上重要である。しかし排水処理において全有機体炭素（TOC）が同じ水でも、処理後の水質に差が出る事が知られており、溶存有機物（DOM）を構成する成分群とその存在率を把握することは重要である。本報では膜分離活性汚泥法を用いた排水処理プロセスにおいて、各サンプルに含まれる蛍光性溶存有機物を三次元励起蛍光スペクトル法（EEM）と多変量解析法(PARAFAC）を用いて測定解析し、排水処理プロセスにおける各成分群の挙動を分析した。また生物難分解性有機物の相対的指標として用いられるSUVAとPARAFAC解析結果との比較を行った。
In sewage and industrial wastewater treatment facilities, monitoring the concentration of organic material is important for operation and maintenance. However, total organic carbon in the waste water is the same, that there is a difference in the water quality after the process has been known. For the reason, understand the prevalence and component group constituting dissolved organic matter (DOM) is important. In this study, we were measured Chromophoric dissolved organic matter using three dimension excitation-emission matrix and Parallel factor analysis method, and analyze the behavior of each component group in wastewater treatment process using a membrane bioreactor method.And we were compared with PARAFAC analysis results and SUVA which is used as a relative indicator of biological degradable organic flame.
