Nitrogen removal with the combined SHARON (Single reactor system for high ammonium removal over nitrite)ANAMMOX (Anaerobic ammonium oxidation) process using the effluent of ADEPT (Anaerobic digestion elutriated phased treatment) slurry reactor with very low C/N ratio for piggery waste treatment was investigated. For the preceding SHARON reactor, ammonium nitrogen loading and removal rate were $0.97kg\;NH_4-N/m^3_{reactor}/day$ and $0.68kg\;NH_4-N/m^3_{reactor}/day$ respectively. In steady state, bicarbonate alkalinity consumption for ammonium nitrogen converted to $NO_2-N$ or $NO_3-N$ was 8.4 gram per gram ammonium nitrogen. The successive ANAMMOX reactor was fed with the effluent from SHARON reactor. The loading and removal rate of the soluble nitrogen defined as the sum total of $NH_4-N$, $NO_2-N$ and $NO_3-N$ in ANAMMOX reactor were $1.36kg\;soluble\;N/m^3_{reactor}/day$ and $0.7kg\;soluble\;N/m^3_{reactor}/day$, respectively. The average $NO_2-N/NH_4-N$ removal ratio by ANAMMOX was 2.41. Fluorescence in situ hybridization (FISH) analysis verified that Candidatus Kuenenia stuttgartiensis were dominate, which means that they played an important role of nitrogen removal in ANAMMOX reactor.

슬러리 형태의 돈사폐수로부터 자원회수와 질소제거를 위하여 순차적으로 ADEPT(Anaerobic digestion elutriated phased treatment) 공정과 SHARON(Single reactor system High Ammonium Removal Over nitrite)-ANAMMOX(Anaerobic ammonium oxidation)공정을 결합하여 운전하였다. ADEPT 공정은 부하율 3.95 gSCOD/L-day에서 운전되었고, SCOD 생성율과 산생성율은 각각 5.3 gSCOD/L-day와 3.3 gVFAs/L-day(as COD)였다. 가수분해에 의한 VS감소와 SCOD생성율은 각각 13%와 0.19 $gSCOD_{prod}/gVS_{feeding}$였으며, 산생성율은 0.80 $gVFAs/gSCOD_{prod.}$였다. 메탄발효조에서 가스생성율과 메탄함량은 각각 2.8 L/day($0.3m^3CH_4/kgCOD_{removal}\;@STP$) 및 77%였다. 운전조건에서 $NH_4-N$ 94.1% (TKN으로서 86.5%) 및 T-P 87.3%가 제거되었다.
