Research on the Oxidation of Food Waste Via Hydrogen Peroxide and Its Conversion into Small Molecule Organic Acids
The amount of food waste is huge,and efficient resource utilization should be carried out.The main components of food waste are starch,cellulose,protein,fat,etc,which can be converted into resources through chemical oxidation.This project uses hydrogen peroxide as an oxi-dant to oxidize and degrade food waste,achieving the dissolution of small molecule organic matter.The results showed that when the H2O2 addition ratio was 3.5%,the acetic acid production increased with the increase of H2O2 addition ratio,which was about three times that of the control group;Its residual TOC content is the lowest at 42.97%,producing volatile fatty acids such as acetic acid and propionic acid,as well as soluble carbon sources.Hydrogen peroxide oxidation can significantly enhance the organic matter dissolution of food waste and achieve its high-value utilization.
