초록

Manure compost biofilter for reducing ammonia emissions at the active stage of a semi air tight and agitated bed composting of hog manure amended with sawdust were evaluated in the practical composting plant(75 m 5 m $\times$1.4 m deep). During 55 days of composting and biofiltration process, the manure compost biofilter had a ammonia reduction of 91 to 98%. Results showed that the active stage of composting maintained temperatures between 40 and 7$0^{\circ}C$ and fluctuated greatly the ammonia concentrations between 100 and 300 ppm. Ammonia concentrations in manure compost biofiltration reached within a moderate range (2-18 ppm).
