Abstract

The aim of this study was to examine the fate of tetracycline resistant bacteria (TRB) and tetracycline resistant genes (TRG) according to the spatial and operational wastewater treatment factors. As part of the effort, TRB and TRG of water samples at each unit processes of three different wastewater treatment plants (WWTPs) were analyzed over seven month study periods. With the data about different spatial and operating conditions of these WWTPs, TRB and TRGs, principal component analysis (PCA) was performed to find out any general correlation trend. Based on the statistic analysis results, the extent of TRB concentration in the activated sludge (TRBAS) is much related to the TRB concentration in primary clarifier effluent (TRBPE). Also, the study results indicated that the fate of TRB and TRG are significantly affected by the SRT variations.

본 연구의 목적은 하수처리장의 공간적 그리고 운전인자에 따른 테트라싸이클린 내성균(TRB) 및 테트라싸이클린 내성 유전자(TRG)들의 거동을 파악하는데 있다. 이를 위한 노력으로, 세 개의 실제 다른 하수처리장내에서 7개월 이상 각각의 반응조별로 시료를 채취하여 TRB 및 TRG가 분석되었다. 통계 기법은 주성분분석(PCA)을 통해 이들 간에 어떠한 일반적 관계식이 성립하는지 알아보려 노력하였다. 통계 분석결과, 활성슬러지내에 TRB 농도는 1차 침전 유입수에 있는 TRB 농도에 많은 영향을 받는 것을 알 수 있었다. 또한, 본 연구를 통해 TRB와 TRG의 내거동이 하수처리장 SRT 조건에 많이 영향을 받는 것을 알 수 있었다.
