Continuous Treatment of Piggery Slurry using the Thermophilic Aerobic Oxidation (TAO) System

급속액상부숙기술(TAO system)을 이용한 양돈분뇨의 연속처리

TAO system was applied to treatment of piiggery slurry. In the experiments, the volume of influx was differentiated in four types. The features of operation, evaporation rate, and efficiency of successive treatment were drawn. The results are; 1. During the operation, the inside temperature was maintained at over $60^{\circ}C$ with the highest $70.2^{\circ}C$. 2. The evaporation rate of influx volume was 31.4%. And the evaporation volume of per square meter was $108{\;}\ell/\textrm{m}^2$; slightly different from $120{\;}\ell/\textrm{m}^2$ of batch type. 3. The VFAs was decreased by 95% (from $1,538lmg/{\ell}$ in influx to $72.9mg/{\ell}$ in Efflux). Thus, successive operation of TAO system is considered to be possible.
