Abstract
An anaerobic digestion system and an oxidation ditch system were employed in this study to investigate the treatment, handling, and disposal of the confined beef animal wastes. Considering only acid fermentation, the process permits the use of the anaerobic digester under little skilled supervision for manure liquification. Uncontrolled field environmental factors, such as low temperatures, low pH, and intermittent and shock loading do not inhibit the acid forming bacterial activities which are responsible for liquifying the organic solids. The liquified manure is more readily degradable for further treatment, can be returned to the soil for agricultural irrigation, and has less pollutional strength for disposal on land. The anaerobic digestion system for solids liquification can be one answer to handling, holding, and disposing of the confined beef animal wastes. The oxidation ditch system, with a loading of one animal per 60 cu. ft. of liquid volume, provides a potential treatment of beef animal wastes. The two rotors in this system, with a speed of 200 r.p.m. and an immersion depth of 3 inches, are capable of maintaining adequate waste velocity and oxygenation.
