泰东河疏浚工程对通榆河水质的影响

Influence of the Dredging Operation of the Taidong River on the Water Quality of the Tongyu River

为了解泰东河疏浚工程对通榆河水质的影响,于2012年6月8日、9月12日、12月6日,对泰东河沿线以及通榆河东台段进行调查取样,分析施工期间河体水质变化。结果表明,施工期间水质参数基本保持在Ⅱ~Ⅲ类。根据江苏省水环境监测中心盐城分中心2011年、2013年监测资料评价分析,泰东河河道疏浚后,清理了河床淤泥,提高了泰东河的行洪、抗洪以及通航能力,其水质的好转有效地改善了下游通榆河的水质,确保了饮水安全。

To understand the influence of the dredging operation of the Taidong River on the water quality of the Tongyu River,we monitored the water quality during the operation by sampling water along the Taidong River as well as the east segment of the Tongyu River on June 8,September 12,and December 6,2012.The results showed that the water quality essentially maintained at level II and level III during the operation.According to the annual evaluation report in 201 1 and 2013 from the Yancheng Branch of Jiangsu Water Environmental Monitoring Center,the dredging operation of the Taidong River cleared the bottom sediment of the river,and up-graded its protection against floods as well as the capability of navigation.Improvement of the water quality of the Taidong River ef-fectively raised the water quality of the Tongyu River from downstream,ensuring the drinking safety.
