模拟再清淤对南淝河底泥氮磷释放的影响研究
Releases of Nitrogen and Phosphorus from Sediments from Nanfei River After Simulated Follow-up Dredging
摘要
Abstract
Water quality monitoring has shown that nitrogen and phosphorus pollution is still severe in Nanfei River even if dredging has been conducted. Here a simulation experiment was carried out to examine the effect of follow-up dredging on the releases of nitrogen and phosphorus from the sediments using intact columns of the sediments that were previously in situ dredged. In the simulated dredging experi-ment, nitrogen and phosphorus in in situ dredged sediments showed alternative release and adsorption pattern with an interval of 7 d, and reached stability after one month. Our results indicate that follow-up dredging at a depth of 5.9 cm could restrain the releases of nitrogen and phosphorus from the sediments during the short term.关键词
