Abstract: Pig breeding wastewater has the characteristics of complex components and limited treatment capacity. Therefore, bio-ecological technology becomes the key and basic technology for treatment of breeding wastewater from small pig farms. In this study, based on the dry feces process popularized at present, a bio-ecological technology-based combined system with source separation, oxidation pond, three-dimensional bio-filter and constructed wetlands was designed for a small pig farm in Jiangxi Province, and the effect of the system was evaluated. Our results indicated that this system had a high rate of contaminant removal efficiency, and could meet the Discharge Standard of Pollutants for Livestock and Poultry Breeding (GB 18596-2001).
