摘要
污水污泥是城市废水处理后的终端产物,既是一种生物质原料,可以被有效地资源化和能源化,同时又含有大量有毒有害物质,如何妥善地处理处置污水污泥,已成为全社会关注的课题。浅析了污水污泥的处理处置方法以及当前的研究热点和新技术。污泥处理处置的发展方向为减量化、稳定化,以及在无害化前提下的资源化、能源化。
Sludge is the main solid waste from sewage treatment plant. Because of its potential harmful impact on the environment,disposal of sewage sludge is becoming a rising challenge all over the world. Progresses in treatment technology and disposal strategy of sewage sludge are discussed. As a kind of biomass,the future direction of sludge treatment and disposal will be reduction,stabilization,resourceful utilization and energy recovery on the premise of harmlessness.
