长春市伊通河北北段底泥清淤处理处置设计探讨

Discussion on treatment and disposal design of sediment dredging in north-north section of Yitong river in Changchun city

伊通河北北段内源污染严重,底泥量巨大。为高效、合理、经济地对底泥进行处理处置,在泥质分析过程中将底泥分为水利高程之上重金属超标底泥、水利高程之上非重金属超标底泥及水利高程之下底泥3个部分,各部分根据具体的底泥特性及最终去向进行合理的处理处置。多元化的处理处置方式为河道内源治理提供了新手段、新理念。

The north-north section of Yitong River is seriously polluted by internal pollutants, and the sediment quantity is huge. In order to treat and dispose the sediment effectively, reasonably and economically, the sediment is divided into three parts in the features analysis process: the sediment above the water conservancy level which exceeds the standard of heavy metals, the sediment above the water conservancy level which is not above the standard of heavy metals, and the sediment below the water conservancy level. Each part is reasonably treated and disposed according to the specific sediment characteristics and final destinations. Diversified treatment and disposal methods provide new means and new ideas for river source internal management.
