Development of the dry methane fermentation system for livestock manure-experimental study on rotational drum fermentation

摘要

Attempting to characterize the Rotational Drum Fermentation System (RDFS), which seemed to be available for anaerobic treatment of non- or low water-dilution livestock manure (called here Dry Methane Fermentation (DMF)), two sets of experiments were conducted. The basic data including pH. VA, TS, VSS and weight reduction of the fermentors containing the various water-diluted slurry of the manure and th anaerobic sludge were determined respectively for the two batch experiemnts. The results indicated that the rheological property of raw livestock manure was imporved considerably after several hours since RDFS start-up and averaged 33
