摘要:
电子束辐照技术在剩余污泥处理应用中具有巨大潜能.大量研究表明,经高能电子束辐照,污泥中的各种病原菌会有不同程度的死亡、有机物(包括非生物降解物质)大量分解、脱水率提高,臭味减少,危害性降低和资源化应用潜能增加.综述了电子束辐照技术在剩余污泥处理中的优势,重点介绍该技术的应用现状、污泥中污染物的去除机理、处理效果和相关建设费用,并展望了该高新技术的应用前景和发展方向.
Abstract:
Recently, electron beam irradiation has great potential in dealing with excess sludge . A great deal of studies showed that the electron beam irradiation played an enormous role in promoting the sludge harmless treatment. Most of pathogenicbacteria was dead and lots of organic substances, especially some non-biodegradable ones, were decomposed by the high electron beam irradiation. The irradiated sludge also had low water content, less odour, low hazard and a better application potential in utilization. This paper reviews the application of electron beam irradiation on excess sludge, the advantages and current situation of the irradiation technology. Mechanisms of removing contaminants, effects of treatment and the construction expense are mainly discussed. The future development of this advanced technology are prospected finally.
