초록

본 연구에서는 J 하수 처리장의 최종 방류수를 대상으로 종속영양세균의 증식과 수중 물리, 화학적 영향인자와의 관계를 고찰하였다. 하수 중의 용존 유기물질 농도는 종속영양세균의 성장과 가장 밀접한 관계를 보였다. 미생물의 영양원인 단백질, 지방, 전분, 섬유소, 팩틴의 분해 세균 분포를 파악한 결과 하수 중 단백질 및 지방세균의 비율은 전체의 81%로 가장 높았다. 종속영양세균은 연중 8월에 가장 높은 수치를 나타냈다. 하수 방류수에 대해 10 mg/L의 유리염소를 주입하여 15min간 접촉시 THMs의 농도는 71 μg/L (< 100 μg/L- 먹는 물 수질기준)의 값을 나타내어 높지 않았다.

We evaluated the relationship between the multiplication of heterotrophic microorganisms and physicochemical factors in the final discharged sewage water from J municipal waste water treatment plants. Dissolved organic carbon (DOC) was the most crucial factor influencing multiplication of heterotrophic plate counts (HPC) among the water quality variables selected. Degrading bacteria, such as proteolytic bacteria, lipholytic bacteria, starch degrading bacteria, cellulolytic bacteria, and pectinolytic bacteria, were monitored to understand the condition of nutrients in finished sewage effluent. The percentages of lipid and protein combined occupied 81% in finished sewage water. The multiplication of HPC showed the highest value in August. The formation of trihalomethane (THM) was low in the finished discharge water during chlorine disinfection, which was 71 μg/L (which was less than 100 μg/L- the standard of drinking water quality) with 10 mg/L of chlorine during 15 min.
