  • 환경시료에서 많이 분리되는 장내바이러스 중 폴리오바이러스, 콕사키바이러스, 에코바이러스를 이용하여 정수처리 공정별 제거율을 조사하였다. 양성 시료로 사용된 바이러스들의 회수율은 72-108%의 범위로 나타났다. 이들 3종 바이러스들을 대상으로 정수처리공정별 제거효율을 조사한 결과 약 99%의 바이러스가 침전단계에서 제거되어졌고, 후오존과 BAC 여과과정을 거치면서 100% 제거되어짐을 확인할 수 있었다. 6개의 세포주를 사용하여 바이러스별 감수성을 조사한 결과 폴리오바이러스는 BGMK 세포주, 콕사키바이러스는 Vero 및 BGMK 세포주가 다른 세포주에 비해 높은 감수성을 나타내었고, 반면 에코바이러스는 RD 세포주에서 가장 분리가 용이하였다.

  • There has been an accelerating increase in water reuse due to growing world population, rapid urbanization, and increasing scarcity of water resources. However, it is well recognized that water reuse practice is associated with many human health and ecological risks due to numerous chemicals and pathogenic microorganisms. Especially, the potential transmission of infectious disease by hundreds of pathogenic viruses in wastewater is one of the most serious human health risks associated with water reuse. In this study, we determined the response of different bacteriophages representing various bacteriophage groups to chlorination in real wastewater in order to identify a more reliable bacteriophage indicator system for chlorination in wastewater. Different bacteriophages were spiked into secondary effluents from wastewater plants from three different geographic areas, and then subjected to various doses of free chlorine and contact time at $5^{\circ}C$ in a bench-scale batch disinfection system. The inactivation of ${\phi}X174$ was relatively rapid and reached ~4 log10 with a CT value of 5 mg/L*min. On the other hand, the inactivation of bacteriophage PRD1 and MS2 were much slower than the one for ${\phi}X174$ and only ~1 log10 inactivation was achieved by a CT value of 10 mg/L*min. Overall, the results of this study suggest that bacteriophage both MS2 and PRD1 could be a reliable indicator for human pathogenic viruses for chlorination in wastewater treatment processes and water reuse practice.
