污泥重金属的非生物处理方法研究进展

鉴于传统的处理方法、尤其是生物处理方法，在处理重金属污泥时的不经济和效率低下，因此，着重介绍了重金属污泥的几种非生物处理方法（电化学方法、微波法、酸化法、离子交换法、络合剂法、吸附法、氨浸法等）的行为机制、研究进展和实际应用等，并对这些方法的处理效果和环境安全作了比较。电化学方法由于见效快、效率高、操作简便且无二次污染，目前已引起环境科学家的广泛关注。

Advance on Non- biological Processes for Removal of Heavy Metal from Sludge

Conventional treatment technologies, especially biological methods for soil stabilization or removal of heavy metals from huge quantity of sludge are not economical and efficient, The purpose of this paper is to review the available information on various attributes of utilization of non - biological technologies for heavy metal remediation, such as electrochemistry, acidification, ion - exchange, complexation, and adsorption, etc. Most of the studies on non - biological way were performed using single physic - chemical technology, which show less advantage in cost and security. Therefore, being integrated by other technologies, the innovatory electrochemical method is of growing concern in this field.
