摘要：With surplus sludge after being treated for 30 minutes at 5MPa, 150℃ as matrix, the operating efficiency of mesophilic two-phase anaerobic digestion system was examined.The result showed that the removal rate of sludge VS decreased as organic load increased and the removal rate of the system VS was 59.4%, 54.7%, 50.21%, and 42.2% respectively when the organic load was 0.98, 1.57, 2.35 and 3.13kgVS/m3•d.If acidogenic phase controlled in ethanol-type fermentation period, the specific hydrogen production of acidogenic phase in this condition achieved 0.018 L•H2/g•VS.When the two phase anaerobic digestion system organic load at 3.13 kgVS/(m3•d), the removal rate of acidification phase and the two phase system VS removal is 15.7% and 42.2% respectively.In anaerobic digestion acidification stage portion EPS from activated sludge floc in vivo release, such as the release of methane-producing bacteria Extracelluler Polymer Substances （EPS） could not be timely use will result in the increase of sludge EPS impact sludge settling and dewatering performance.
