Abstract

In view of the characteristics of food waste, large volume and constant output in universities, taking a Chinese University as an example, we explored the centralized mode of kitchen waste biogas disposal in universities. The anaerobic fermentation technology is the core of the design, and the "canteen + garden" engineering mode is adopted, converting organic waste into energy and organic fertilizer through this process. According to the daily average throughput of 5t, a continuous stirred tank reactor (CSTR) 300m3 is needed. The results show that an average annual treatment capacity is 1200t mixed organic wastes, the annual output of organic fertilizer raw materials such as biogas slurry and biogas residue is 370.8t and annual biogas output is 144,000m3. Biogas supplies the canteen, biogas slurry produces organic fertilizer, and the treated biogas slurry is discharged. This scheme can effectively improve the environment of the campus and establish the basic mode of circular agriculture.
