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.
With the enclosed grade of water circulation increasing in pulp and paper making mills, Dissolved and Colloidal Substance (DCS) accumulated gradually. Too much DCS has done harm to the stability of paper machine operation and the quality of products. It requires effective ways to deal with this problem. The anaerobic biodegradability of water samples being rich in DCS and DS was comparatively researched through the laboratory experiment. It showed that DCS and DS all had good anaerobic biodegradability, the removal rates of COD respectively reached 73.35% and 73.4%. Lignins in CS and DS also had good anaerobic biodegradability, the removal rate reached above 70%, and the removal rate of lignins in DS was even up to 92.5% Analysis indicates that some of the CS by biological decomposition will be converted into DS which is non-biodegradable.
