| 摘 要： | 通过竺山湖底泥疏浚表层50 cm模拟试验,疏浚柱间隙水硝态氮浓度为0.02～0.48 mg/L,高于对照柱0.05～0.08 mg/L,疏浚柱和对照柱沉积物反硝化速率分别为5.6～25.6和21.3～95.6 nmol/(g.h),疏浚柱反硝化速率降低,说明底泥疏浚对竺山湖沉积物反硝化具有负面影响。

| Abstract: | Through simulation test of 50 cm surface layer of sediment dredging from Zhushan Lake,the NOx-N concentration of the dredged cores were among 0.02-0.48 mg/L,which was higher than control cores of 0.05-0.08 mg/L,the denitrification rates of the dredged and control cores were among 5.6-25.6 and 21.3-95.6 nmol/(g·h),respectively.The denitrification rate in the dredged cores was lower than those in the control cores.Our results suggested that sediment dredging of Zhushan Lake may has a negative effect on denitrification of nitrogen. |
