摘要
Under high temperature condition, the effects of inoculation rates and moisture contents on anaerobic digestion of air-dried food waste were studied. The results showed that air-dried food waste could effectively alleviate the acidosis at the initial acidification phase. The interaction of inoculation rates and moisture contents makes an impact on the methane production. High inoculation rate and low moisture content is advantage to anaerobic digestion of air-dried food waste which gives the system a higher buffer capacity. When the inoculation rate is 55% and the moisture content is 92%, the process of anaerobic digestion operates normally with the methane production rate of 0.246L/g. The highest methane production rate reaches to 0.471L/g at 75% inoculation rate and 88% moisture content. The removal rates of COD and TS increase with inoculation rate, and the highest is 91.6% and 32.7%, respectively.
