太湖底泥的污染控制及修复技术的可行性应用探讨

Discussion on Feasible Application of Pollution Control and Remediational Techniques to Sediment of Taihu Basin

太湖表层底泥营养物、重金属和有机污染物等含量较高,并有向水体释放倾向,对水体及水生生态系统造成威胁。文章探讨了对太湖已开展或近期可开展的内源污染治理实用和示范技术,如外部污染源控制、原位覆盖、原位底泥氧化、原位上覆水充氧、生态疏浚、生物修复技术以及自然消减技术等。对上述技术运用于太湖进行了可行性分析。

Bottom sediment of Taihu Basin contains a lot of pollutants, such as nutrition, heavy metals and organic matter. Releasing pollutants from the bottom sediment of Taihu Basin has become one of the major factors affecting ecological health of Taihu Basin. In this paper, Practical and demonstrative techniques of internal pollution treatment in Taihu Basin which have been used or will be used soonly have been explored, including controlling the sources of pollutants, in-situ capping, in-situ oxidizing, in-situ supplying oxygen, dredging, Bioremediation and natural reduction, and feasiblity analysis on the application of these techniques in Taihu Basin has been made.
