This study was carried out to obtain the optimal ammonia removal efficiency using pyroligenous liquid for the economical and environment-friendly odor removal at a petty livestock farmhouse. The ammonia removal efficiencies were evaluated due to changing dilution rates(×10, ×20, ×30, ×50 and ×100 times) and different spray amounts(10㎖ and 20㎖) of pyroligenous liquid. The wet scrubber device was used to remove odor in closed-type livestock farmhouse.
According to dilution rate of the pyroligenous liquid, the optimum rate was 20 times and the removal efficiency increased by decreasing dilution rates. In the case of spray amounts with the optimum dilution, the amount was 20 ㎖ and the removal efficiency increased by increasing spray amount. Also, the removal efficiency by using wet deodorizing device was 83.0～97.0% with 20 times diluted liquid.
