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 application of nitrate is an accepted procedure to manage eutrophication municipal rivers by controlling the phosphorus release from sediments into overlying water and offering electron acceptor for microorganism metabolism. An in-situ-experiment was carried out to oxidize the sediment by direct calcium nitrate injection. Phosphorus release from sediment injected calcium nitrate was almost stopped during the experiment. Calcium nitrate can greatly improve the ability of bio-treatment properties for sediment. After 30 weeks of treatment, the sediment TOC decreased by 10.5%, 9.5% in reactor with a dose of 140g and 70g per square meter NO3-N, respectively. The TN concentration with dose of 70g per square meter NO3-N can reduce to common level compared to blank reactor by denitrification. It makes in-situ chemical remediation technology by calcium nitrate injection become possibly.
