Abstract

A method for cyclic utilization of rejected biomass includes such steps as decomposing in a multi-class fermenting pool, gas-solid-liquid separation, desulfurizing the marsh gas containing H2 and methane, feeding the marsh gas in the fuel battery with anionic exchange membrane, generating CO2 at negative electrode, using the separated liquid for soilless culture of plants, using said fuel battery to power the artificial light source, and using the residual dregs as the crop culturing matrix or organic fertilizer.

Description

technical field [0001] The invention relates to a technology for comprehensive utilization of biomass waste, more specifically, the invention relates to a method for recycling biomass resources. Background technique [0002] The utilization of biomass waste has many specific applications, which can be generally summarized as energy utilization and resource utilization of biomass waste. Among them, the energy utilization of biomass waste is the mainstream of research at home and abroad, but the resource utilization of biomass waste has not yet formed a scale. [0003] (1) Energy utilization of biomass waste [0004] In terms of biomass energy utilization, the biogas power generation technology that converts biomass waste into electricity and heat energy through anaerobic fermentation to obtain biogas has become a representative research direction. Biogas power generation technology can be roughly divided into two categories: one is to obtain electricity through gas combusti...
