Review on Acetic Acid Preparation and Application By Anaerobic Fermentation of Kitchen Waste
The production of kitchen waste has increased rapidly with the implementation of garbage classification in China.However,the low utilization rate of biogas,low added value of products and high cost of biogas slurry treatment led to poor economic benefits of the mainstream anaerobic digestion project,which promoted the utilization technology of kitchen waste to be upgraded.Organic acids prepared in the anaerobic fermentation of organic matter are widely used,among which acetic acid can be used as basic raw material in pharmaceutical and chemical industries.In recent years,the demand of bio-based acetic acid is increasing,due to energy crisis,raw material scarcity and environmental problems.Acetic acid prepared by fermentation of kitchen waste might provide a new way for high-value utilization of organic solid waste and low-carbon energy transformation.In this paper,the biological metabolic mechanism,the influences of different parameters and the reinforcement strategies of acetic acid production in organic waste anaerobic fermentation treatment were expounded,so as to provide references for the practical engineering application of anaerobic acetic acid production of kitchen waste.
