Protected area of water for supply source is located mostly of rural area in Korea. Normally, sewage treatment system
is poor to manage in rural, because low population and density. Rural area need sewage treatment system to supervise
supply source of water. In this study, analysis on operation result of 4 RCSTP and MWTP is located at the rural area.
Higher concentration of pollutant were inflows to MWTP than RCSTP, and effluent quality standard is satisfaction.
However, RCSTP effluent pollutant concentrations was researched higher than MWTP. The organic matter(BOD,
COD) were about 5% of a high treatment efficiency to a median. The nutrient(T-N, T-P) were detected Up to high
30%. Also, we analyzed to effect reactor operational parameters on the pollutant treatment efficiency like mixed
liquer suspended solid(MLSS), dissolved oxygen(DO) and sludge retention time(SRT). As a result, pollutant treatment
efficiency showed fluctuation in accordance with operating condition. Thus, it is necessary to manage the reactor
operation condition for management of rural area sewage treatment.
