Abstract
Provided is a method for evaluating a pretreatment effect for organic solid waste based on fractal dimension, relating to biological conversion of organic solid waste. Samples of the organic solid waste are collected, and dried and broken up to obtain dried samples. The mixtures obtained are analyzed using a laser particle size analyzer, so as to measure a wave vector Q and a scattering intensity I of each of the mixtures. According to a fractal theory, the wave vector Q and the scattering intensity I obtained are analyzed using a data processing software to obtain a two-dimensional fractal dimension Df of each of the samples. Based on data from documents and experiments, a total organic carbon or an apparent activated energy is evaluated, so as to evaluate the pretreatment effects of samples of the organic solid waste.
