Oklahoma State University Swine Research and Education Center Manure Handling and Utilization System

摘要

In 2004, Oklahoma State University moved its porcine teaching and research facility to a new location. A major emphasis of the move was to demonstrate state-of-the-art manure handling. The farm is a 130 sow farrow-to-finish operation. Animals are housed in 12 small, modular buildings. Manure is removed using scrape-assisted, recharge pits. The manure handling system provides three layers of treatment with two lagoons and an anaerobic digester, followed by subsurface drip irrigation. The lagoons and digester can all be operated independently, and each was designed to treat the entire manure flow from the facility.
