污泥生物炭的研究进展

摘要

In recent years,in China the amount of sludge in wastewater treatment plants has been increased grad-ually with the improvement of wastewater treatment efficiency.Sludge innocence,reduction and reuse have be-come an important topic in the field of environment protection.In this paper,the compositions and structure characteristics of sludge biochar were analyzed on the basis of summarizing the preparation methods.Further-more,the application of sludge biochar at home and abroad was also summarized from the aspects of water pol-lution control,air pollution control,electrochemistry and soil remeditaion.Finally,the directions for the re-search and application of sludge biochar was predicted.%伴随着我国污水处理率的逐年提高,污泥产量也不断增多,污泥的无害化、减量化与资源化成为环境保护研究的重点.利用污泥制备生物炭并加以应用是一种有效的污泥"三化"处理措施.在归纳污泥制备生物炭方法的基础上,详细分析了决定污泥生物炭应用前景的组成和结构特性.进一步从水污染控制、大气污染控制、电化学和土壤修复等方面总结了国内外污泥生物炭的应用情况,并指出了今后污泥生物炭研究与应用的发展方向.
