Abstract
Provided is a method for evaluating a bioavailability of organic solid waste by an anaerobic conversion based on fractal dimension, relating to anaerobic digestion of organic solid waste. Organic solid waste is broken up and dried, and the organic solid waste is analyzed using a laser particle size analyzer, so as to measure a wave vector Q and a scattering intensity I. The wave vector Q and the scattering intensity I are analyzed using a data processing software, and a two-dimensional fractal dimension Df is obtained based on a fractal theory. A volatile fatty acid maximum VFAmax and a biochemical methane potential BMP of the organic solid waste are predicted according to the two-dimensional fractal dimension Df, so as to evaluate a bioavailability of organic solid waste by an anaerobic conversion.
