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.
The effects of HRT and MLSS on nitrogen and phosphorus removal in a continuous shortcut nitrification-denitrification reactor are experimentally studied with artificial domestic sewage. The results show that when HRT is controlled at 8h, the sewage treatment efficiency is the highest and the accumulation rate of NO2--N reaches maximum. Too long or too short HRT is not conducive to stable treatment. It is also found that as MLSS raises to 5000mg/L, the release of anaerobic phosphorus, the uptake of anoxic phosphorus and the accumulation rate are all up to maximum. If MLSS is more than 5000mg/L, the accumulation rate of NO2--N will be decreased, leading to low removal rate of PO43-P duo to the secondary phosphorus release in anoxic zone.
