AI Technical Summary
In existing technologies, during the anaerobic digestion of kitchen waste, components such as protein and cellulose are difficult to biodegrade, resulting in low digestion efficiency. Furthermore, commercial peracetic acid solutions have low utilization rates, high storage and transportation costs, and pose a risk of secondary pollution.
Using a RuO2/Ti mesh electrode as the anode and a graphite plate electrode as the cathode, peracetic acid is synthesized and activated in situ via an electrochemical method. Peracetic acid is generated directly during the anaerobic digestion of kitchen waste as a substrate, thereby degrading recalcitrant organic matter.
It improves the anaerobic digestion efficiency of kitchen waste, solves the problems of low reagent utilization and high storage and transportation costs in traditional chemical pretreatment, realizes the resource utilization of small molecule acids, reduces operating costs, and avoids secondary pollution.
