    Abstract: Volatile fatty acids (VFAs) are products with high added value and widely used. The production of organic acids by anaerobic fermentation of biomass is an environmentally friendly method and can realize the recycling of waste. In order to solve the problem that biomass structure is complex and difficult to hydrolyze, three pretreatment methods, sol... Show More

    Abstract: In this paper, the cement base and steel fiber are modeled separately through a separate model. The cement base uses a concrete damage plastic model; while the steel fiber imports the programmed program into the simulation software to generate randomly distributed steel fibers, and the steel fiber uses a truss unit. After the separation model is mo... Show More
