持久性有毒物污染底泥修复技术进展

Progresses in remediation technologies for persistent toxic substances polluted sediments

评述了底泥中持久性有毒污染物的危害。在分析持久性有毒污染物污染底泥修复技术现状及面临问题的基础上 ,指出浅水湖泊持久性有毒污染物污染底泥修复的发展方向是植物 -微生物联合修复 ,水库、深水湖泊等持久性有毒物污染底泥修复的发展趋势为物理化学 -生物协同修复 ,修复目标是在环保疏浚、生态清淤的基础上 。

The toxicity of persistent toxic substances (PTS) in sediments and the present remediation technologies for PTS polluted sediments and their main questions were reviewed in this paper.Furthermore,the authors pointed out that the combination of plants with microorganisms technologies should be the future trend for remedying such sediments in shallow lakes;while physiochemical biological technologies should be used in reservoirs and deeper lakes in the furture.The final purpose of such remediation is to obtain non toxic and resources disposal of PTS polluted sediments on the basis of dredging and ecological cleaning.
