Abstract

This study was conducted to investigate the emission characteristics of ammonia and hydrogen sulfide during the process of aerobically treatment liquid swine manure in swine farms. This study was performed by selecting three farms located in Chungchungbuk-do, South Korea. To analyze odor compounds emitted from the process of aerobically treatment liquid swine manure in swine farms, odor samples and swine manure samples were collected at aerobically treatment stages, including slurry, solid matter after solid-liquid separation, aeration process, settling process, and storage process. The concentration of ammonia and hydrogen sulfide were then analyzed at each stage. Overall, ammonia, hydrogen sulfide, and odor intensity did not show any significance during the process of aerobically treatment liquid swine manure. In Farm A, hydrogen sulfide (P=0.074) and odor intensity (P=0.053) linearly tend to decrease as the process of aerobically treatment liquid swine manure. Hydrogen sulfide was not detected in the samples from sample of Farms B and odor intensity showed that linearly tend to decrease as the process of aerobically treatment liquid swine manure (P=0.097). positive correlation was found between hydrogen sulfide and odor intensity (P<0.001). This study provides information into the emission characteristics of ammonia and hydrogen sulfide during the process of aerobically treatment liquid swine manure in swine farms, serving as foundational data for research aimed at odor reduction.
