Abstract
The combined ADEPT(Anaerobic Digestion Elutriated Phased Treatment)-SHARON(Single reactor system for High Ammonium Removal Over nitrite)-ANAMMOX(Anaerobic ammonium oxidation) processes were operated for resources recovery and nitrogen removal from slurry-type piggery waste. The ADEPT process operated at an acidogenic loading rates of 3.95 gSCOD/L-day, the SCOD elutriation rate and acid production rate were 5.3 gSCOD/L-day and 3.3 gVFAs(as COD)/L-day, respectively. VS reduction and SCOD reduction by the hydrolysis were 13% and 0.19 $gSCOD_{prod.}/gVS_{feeding}$, respcetively. Also, the acid production rate was 0.80 $gVFAs/gSCOD_{prod}$. In methanogenic reactor, the gas production rate and methane content were 2.8 L/day($0.3m^3CH_4/kgCOD_{removal}@STP$) and 77%, respectively. With these operating condition, the removals of nitrogen and phosphorus were 94.1% as $NH_4-N$(86.5% as TKN) and 87.3% as T-P respectively.
