摘要
概述了国内外电动力学去除技术的研究现状以及污泥中重金属离子的存在形态、水解引起的pH变化、电极极化、外加酸和螯合剂、电流和电压等对该技术的影响。阐明了利用电动力学去除技术去除剩余污泥中重金属离子的可行性。指出了今后电动力学去除技术重点研究的方向。
The status of research on electrokinetic removal technology at home and abroad is introduced.And the affecting factors are summarized,such as: form of heavy metal ions in sludge,variation of pH caused by hydrolysis,polarization of electrode,added acid and chelating agent,current and voltage,and so on.The feasibility of electrokinetic technology for removal of heavy metal ions from excess sludge is clarified.The directions for further research are pointed out.
