A STUDY ON THE EFFECT OF MUNICIPAL WASTEWATER IN WET WEATHER ON THE DYNAMICS OF DISSOLVED ORGANIC MATTER IN RIVER WATER BY USING EEM-PARAFAC

Abstract

 EEM-PARAFAC analysis was applied to reveal the dynamics of dissolved organic matter (DOM) contained in effluent water in Sewage Treatment Plant (STP) and river water at Katsura-river in wet weather. The objective of this study is to evaluate water quality change of effluent water in STP and river water by combined sewer overflow (CSO) and sanitary sewer overflow (SSO).
 As a result of the water sampling survey, the main component of DOM, which had the largest influence on the quality of river water by CSO and SSO, was a protein-like component.
 The above results suggested that it is effective to constantly monitor this component with a fluorescent sensor as a simple alternative indicator of dissolved organic carbon (DOC) in evaluation of effluent water quality and river water quality by CSO and SSO.
