Study on Technology of Food Waste Biological Aerobic Composting

摘要

The compositions of food waste were complex, and the content of organic matter was high, so food waste was suitable for being disposed with aerobic composting manner. Degradation time, strains inoculation quantity, waste moisture content and temperature of degradation were the main factors of affecting the food waste treatment effect and through the regulation of these factors can change the organic matter degradation ratio of biological degradation. Make use of existing food waste processing equipment to dispose food waste, the inoculation amount of food waste was in accordance with the ratio that auxiliary material (including bacteria strains): food waste =4:3, meanwhile, the degradation temperature was adjusted to 40°C, and the moisture content was changed to 40%. After 7 days, the output materials of food waste degradation would be used in the cultivation of vegetables as organic fertilizer.
