湖泊底泥污染控制技术及其适用性探讨

对目前国内外应用较多的三类底泥污染控制技术,即环保疏浚技术、原位覆盖技术、原位钝化技术的技术特点、关键技术内容、可能产生的主要环境问题及其应用现状进行了详细分析.在各项技术的优缺点、费用效益比较的基础上,提出环保疏浚技术适用于大面积重污染湖区或河口底泥污染的控制,原位覆盖技术适用于中深水湖泊、海域或河流底泥污染的控制,原位钝化技术适合于风浪扰动不大、非饮用水源地功能湖泊底泥污染的控制.并对三项技术在我国湖泊底泥污染控制领域的应用前景进行了展望.

on the applicability in lakes of China

This article intends to give a systematic review of three sediment pollution control techniques,that is environmental dredging technology,in-situ capping technology,and in-situ inactivation technology,which have been applied successfully in many cases home and abroad.Through a detailed summary,the three techniques have been clearly displayed about the characteristics,main technical processes,primary environment problems during construction and application status,etc.On comparision of advantages and disadvan...
