Interpretive Summary:

Technical Abstract: There is a need for treatment technologies that can eliminate environmental problems associated with anaerobic lagoons. These technologies must be able to capture nutrients, kill pathogens and reduce emissions of ammonia and nuisance odors. To meet these needs, a full-scale wastewater treatment plant was demonstrated in one of three 4,360-pig production units in a finishing farm in Duplin Co. Once the treatment plant was operational, flow of raw manure into the corresponding lagoon was discontinued and the lagoon was used to store treated wastewater. Water quality was monitored in the converted lagoon and in the two traditional lagoons. A gas chromatography method was developed to measure concentration of odor compounds in both air and liquid lagoon samples. Concentrations of odor compounds contained in air and liquid were significantly reduced in samples from the converted lagoon as compared to air and liquid from the two traditional lagoons. The reduction was particularly marked in the case of p-cresol, ethylphenol, and skatole, all of which make important contributions to swine waste odors due to their low detection thresholds.
