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 Waigang River, a major tributary of Qinhuai river systems in the Nanjing city, China, had suffered long-time pollution due to lack of management. Restoration was commenced from April, 2006. Four Ecological Areas and 10 Surface Carriers were constructed and water hyacinth was cultivated for phytoremediation. Chemical oxygen demand (COD), total suspended solids (TSS), total phosphorus (TP), total nitrogen (TN), NH3-N, diaphaneity and variation of phytoplankton were investigated. After 9 months of restoration, TSS, COD, TN, TP and NH3-N decreased evidently. Diaphaneity was enhanced from 23cm in July to 120 cm in December and even to 160cm in some areas. Diversity of phytoplankton which was destroyed by extreme pollution was improved due to improvement of water quality. Cyanobacteria burst up in August and dropped subsequently. Proportion of Bacillariophyceae and Chlorophyceae in all algae increased, but amount of phytoplankton exhibited a falling trend during the process of phytoremediation. Our results showed that water hyacinth cultured in the Ecological Areas and the Surface Carriers could be applied to remediation of heavily polluted river and variation of phytoplankton also reflected the changing of water quality.
