[Start-up research of single phase high solid anaerobic digestion technology for organic waste].
Under mesophilic condition (35 degrees C), a bench-scale experiment based on high solid anaerobic digestion process was conducted in a fed-batch single phase reactor. At the start-up stage, the feeding amount of organic waste was modified with the variation of pH value and gas production. The results of this stage showed that 705.77 L of gas production per kg VS added was obtained while the total solids content of the feeding waste was 24.79% and the VS content was 93.04% of TS. After 30 days of the start-up, the pH value ranged between 6.9 and 7.3 in the reactor, and after 50 days the organic loading rate (VS) reached 6.98 kg/(m3 x d) with an HRT of 35 days.
