Abstract

As the concentration of nitrogen in the sewage flowing into the sewage treatment plant increases due to urbanization and industrialization, the degree of adverse effects such as eutrophication and toxicity to the aquatic ecosystem is also increasing. In order to treat sewage containing high concentration of nitrogen, various studies on the biological nitrogen removal process are being conducted. Existing biological nitrogen removal processes require significant costs for supplying oxygen and supplementing external carbon sources. In this respect, as a high-level nitrogen removal process with economic improvement is required, an anaerobic ammonium oxidation process (ANAMMOX), which is more efficient and economical than the existing nitrification and denitrification processes, has been proposed. The purpose of this study is to confirm the stability of the ANAMMOX process in the water treatment process and to derive the ratio of ammonia nitrogen (NH4+) to nitrite nitrogen (NO2-) for the implementation of the mainstream ANAMMOX process. A laboratory-scale Mainstream ANAMMOX reactor was operated by applying the ratio calculated based on the substrate ratio suggested in the previous study. In the initial range, the removal efficiency of NH4+ was 58~86%, and the average removal efficiency was 70%. In the advanced range, the removal efficiency of NH4+ was 94~99%, and the average removal efficiency was 95%. As a result of the study, as the NH4+/NO2- ratio increased, the stability of the mainstream ANAMMOX process was secured, and it was confirmed that the NH4+ removal efficiency and the total nitrogen (TN) removal efficiency increased. As a result, the results of this study are expected to be used as basic data in the application of the ANAMMOX process in the mainstream.

도시화와 산업화로 인해 하수처리장으로 유입되는 하수 내 질소 농도가 증가함에 따라 부영양화 발생, 수생태계에 독성을 미치는 등의 악영향의 정도 또한 증가하고 있다. 고농도의 질소가 포함된 하수를 처리하기 위해 생물학적 질소 제거 공정에 대한 연구가 다방면으로 진행되고 있다. 기존의 생물학적 질소 제거 공정에 있어 산소공급과 외부탄소원 보충에 따른 상당한 비용이 요구된다. 이러한 측면에서 경제적인 개선이 이루어진 고도의 질소 제거 공정이 요구됨에 따라 최근 기존의 질산화·탈질 공정 보다 효율적이고 경제적인 혐기성 암모늄 산화 공정(ANaerobic AMMonium OXidation, ANAMMOX)이 제안되었다. 본 연구에서는 수처리공정에서의 ANAMMOX 공정의 안정성을 확인하고, Mainstream ANAMMOX 공정구현을 위한 암모니아성 질소(NH4+) 대비 아질산성 질소(NO2-) 비율을 도출하는데 목적이 있다. 선행연구에서 제시된 기질비율을 바탕으로 산정한 비율을 적용해 실험실 규모의 Mainstream ANAMMOX 반응조를 운전하였다. Initial 구간에서 NH4+ 제거효율은 58~86%, 평균 제거효율은 70%였다. Advanced 구간에서 NH4+ 제거효율은 94~99%, 평균 제거효율은 95%였다. 연구 결과 NH4+/NO2- 비율이 증가함에 따라, Mainstream ANAMMOX 공정의 안정성이 확보되어 NH4+ 제거효율 및 총질소(TN) 제거효율이 증가하는 경향을 확인할 수 있었다. 결과적으로, 본 연구결과는 이후 수처리공정에서의 ANAMMOX 공정 적용과 공정 안정성 확보에 있어 기초자료로 활용될 수 있을 것으로 보인다.
