Study on Influencing Factors of Food Waste Biological Aerobic Composting
Home-made food waste disposal equipment was used for biological aerobic composting of food waste.Influences of environment temperature,moisture content and inoculation amount on biological aerobic composting of food waste were studied by orthogonal tests,in which the affecting order of the factors and optimal technological conditions were confirmed.Single factor experiments were done to verify the conclusion.Experimental results showed that the optimal conditions of biological aerobic composting were environment temperature 40 ℃,moisture content 40%,inoculums amount which in accordance with the ratio of that bacteria strains(including auxiliary material) to food waste was 4∶3 and affecting order of the factors as environment temperature,moisture content and inoculation amount.At the optimal conditions,the growth rate of bacteria strains was faster,the activity was stronger and degradation could last for a longer time.The composting products satisfied the organic fertilizer NY 525-2011 standard after inspection.
