Abstract

Supply of rural community sewage treatment plant (RCSTP) is need for protect of water quality like water source and development of agriculture areas. In this study conducted analysis on characteristics of RCSTP sewage and treatment efficiency of installed treatment process using operation results of RCSTP in an-dong area. high organic matter and nutrient were contained in RCSTP sewage of an-dong than urban area. RCSTP treatment process in an-dong was shown stable treatment efficiency. But nutrient treatment efficiency was shown more sensitive result about SRT and F/M ratio than organic matter treatment efficiency. And RCSTP treatment process in an-dong was shown higher treatment efficiency than other treatment proces like $A^2/O$, SBR and media. Thus, this process is effective treatment process for application of RCSTP.

상수원과 같은 수계 수질 보호 및 농촌 지역 개발을 위해 마을하수도 보급이 필요하다. 본 연구에서는 안동 지역 마을하수도(11개소) 유입하수 특성 및 마을하수도에 도입된 처리 공법의 결과를 분석하였다. 안동 지역 마을하수도 유입하수는 도시지역에 비해 고농도의 유기물과 영양염류를 함유하고 있는 것으로 분석되었다. 안동시 마을하수도 공법은 안정적인 처리효율을 보였지만, 영양염류의 경우 유기물에 비해 solid retention time(SRT)와 food to microorganisms (F/M) ratio에 민감한 것으로 나타났다. 또한 안동 지역 마을하수도 공법은 타 공법($A^2/O$, SBR, media)들과 비교하여 전반적으로 높은 처리 효율을 보였으며, 본 공법은 마을하수도에 효과적으로 적용 가능한 공법이라 판단된다.
