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.
Processing high ammonia nitrogen piggery wastewater with the sequencing batch of activated sludge, we research about the key step, shortcut nitrification and denitrification process. We determine the water indicator, with the long-term operation, meanwhile we use DGGE to observe the microbial community of sludge. Results show that, the reactor still can reach 96% removal rate of ammonia nitrogen, accumulation ratio of NO2--N is 68.9% as average, removal rate of COD is 50%, the microbial community structure of sludge is simple, the advantage bacterium is obvious, Shannon index is 1.24 at the begin, reduced volatility, minimum for 0.44.
