| Abstract: |
| The test is conducted on experiments of anaerobic digestion with IC reactor under mesophilic and high temperature conditions for residual sludge from Sanbaotun waste water plant in fushun, and the feasibility of anaerobic digestion process is investigated. The research result shows that the removal rate of COD and pro- ducing air quantities under mesophilic and high temperature conditions are steady after continuous producing sludge respectively for 12 or 8days. The methane content in air is over 70 %. Flocculation experiment shows that the mud cake volume of the equal weight digestive sludge after flocculating is 56 % , compared to raw sludge. |
