餐厨垃圾高温好氧发酵工艺的研究

Abstract

With the rapid urbanization in China, there has been a gradual increase in the production of kitchen waste, which poses significant environmental challenges. High-temperature aerobic fermentation is an effective method for recycling kitchen waste. This study focuses on utilizing kitchen waste, wood chips, and compound microbial agents as the main raw materials for fermentation. Various parameters such as temperature, moisture content, and amount of compound microbial agent were selected to conduct experiments on the high-temperature stage of the aerobic fermentation process for kitchen waste. Through response surface optimization experiments, it was determined that the optimal conditions for achieving fast high-temperature fermentation of kitchen waste are as follows: temperature at 60℃, moisture content at 60%, and amount of compound microbial agent at 10%. The order of influence on the reduction rate of kitchen waste is found to be temperature followed by the amount of compound microbial agent and moisture content. These findings provide valuable insights into resource utilization strategies for managing kitchen waste.
