摘要
介绍了污泥中重金属存在的形态,综述了污泥中重金属去除的常用的四种技术化学浸出、生物浸出、电分离和超临界流体萃取,重点介绍了化学浸取技术的原理和特点,并对诸项技术的优点以及存在的问题进行了评述。
Various methods of heavy metal removal from sewage sludge were extensively studied in order to minimize the prospective health risks of sludge during land application. In this paper, a comparative review and critical analysis of the application of bioleaching, electroreclamation, supercritical fluid extraction and special chemical extraction in removing heavy metals from contaminated sludges were presented.
