Water Purification Effect in the Eco-Remediation Zone in the East of the Gehu Lake
摘要
Abstract
A bio-remediation experiment zone,using a stereo bio-system consisting of submerged,floating-leaf and emergent aquatic plants to purify water was set up at the Xiaomiao Bay in the east of the Gehu Lake.Monitoring of physicochemical indices of the waterbodies in the open waters (CK) and the zone was performed from December 2009 to November 2010.Results show that the bio-remediation was quite effective in removing suspended solids with an average annual removal rate of 24.85%.It also significantly improved transparency of the waterbody and by 11.24% as compared with that in CK.The remediation reduced TP and Chl-a contents by 21.90% and 22.83%,respectively.Moreover,its effects on removal of TN and NH3-N and CODMn were not so significant.It reduced CODMn by 9.49% and NH3-N by 3.52%,only,and however,even increased TN by 6.69%.Its water purification effect varied with the seasons and affected by growth of the aquatic plants.关键词
