Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
By the intermittent experiment, we studied the effects of temperatures on process of hydrolysis and acidification of excess sludge. The results showed that at the temperature of 25°C, 30°C, 35°C and 40°C, the maximum of SCOD reached 382 mg/L, 432 mg/L, 622.51 mg/L and 1453.96 mg/L, and the maximum of hydrolysis efficiency reached 1.03%, 1.33%, 2.14% and 6.28%. The settlement performance increased about 0.50%, 1.00%, 1.80% and 2.40% than the initial value. At the temperature of 35°C, the TF reached the maximum of 19.5011 mg TF/gTSS (h). We can see the activity of micro-organisms was the greatest at this time.
