Abstract

During the aerobic composting of livestock excrement, or leachate, which is generated in the composting process,is distributed through a bulking agent. In this research, a specific microorganism expected to reduce the emissionof odor was activated in livestock excrement supernatant, which is similar to the leachate used for water control.While the microorganism was being diffused, odor properties were examined. The bulking agent, in which thespecific microorganism was activated, was produced by applying a bioreactor filled with pumice and pellets tothe treatment process of livestock excrement activation sludge method. The dominant microorganisms werePseudomonas genera. Experiment results showed ammonia content was lowered as to 0.27ppm 1n 15 days;however, it remained at levels of 3.15ppm in the control reactor. After the composting time was completed, theammonia concentrations were 0.07ppm and 3.43ppm, respectively. The complex odor in the test reactor was28~30 times greater than of dilution, but was 42~45 times greater in the control reactor. Hydrogen sulfide andmethyl mercaptan were not detected in either reactors. Ammonia was thought to be the major odor-producingsource during the aerobic composting process of livestock excrement, and it was expected that the odor could bereduced by spraying a microorganism -activated solution as a bulking agent.
