Abstract

This study performed verification experiment for the removal of total nitrogen in sewage from a Town M village sewage treatment plant using YPNR processes. The total nitrogen discharged after the denitrification process was maintained at a level of 8-15 mg/L, which results in the total nitrogen removal efficiency above 68% on average. The total nitrogen components in discharged water consisted of 16% of ammonia nitrogen, 6% of nitrite nitrogen, and 77% of nitrate nitrogen, which reaches a 95% nitrification efficiency. Hence, the YPNR advanced treatment process used in this study can be successfully applied to sewage treatment.

본 연구는 오 폐수 내에 존재하는 총질소 성분의 생물학적 처리공정의 실증께 관한 연구를 수행한 것으로써 M면의 마을하수처리장에 YPNR 고도처리 공법을 적용하여 25일의 처리기간 동안 마을하수 중의 총질소 성분의 제거에 관한 자료를 확보하여 얻은 결론은 다음과 같다. 마을하수처리현장에 적용한 결과, 첨가탄소원 없이도 현재 배출허용기준에 적합한 70% 정도의 질소처리 효율을 나타내었다. 특히 유입 총질소 성분 중 95%는 질산화공정을 통해 질산성 질소로 전환되어 탈질공정에서 제거되고 방류되는 총질소 성분 중 질산성 질소 성분이 약 77%로서 이는 향후 강화되는 총질소 규제시 외부탄소원을 소량 투여해 줌으로써 현재의 방류수질보다 약 70% 낮은 방류수질을 유지 할 수 있을 것으로 생각된다. 결론적으로 본 실험에서 사용된 YPNR 고도처리 공정은 하수, 마을하수처리에 적용될 수 있다고 판단된다.
