燃煤电厂污泥掺烧技术及其研究进展

随着我国城市化进程的加快,城市生活污水量急剧增加。污泥作为污水处理后的附属产品,对环境影响极大,因此污泥的无害化、减量化、资源化处理迫在眉睫。燃煤电厂污泥掺烧是实现最大体积减少污泥的处置方法之一。发达国家和地区中,污泥掺烧工艺已逐渐成熟,在燃煤电厂的应用更为广泛。综述了污泥掺烧技术的现状,分析了燃煤电厂掺烧污泥造成的影响,并讨论了燃煤电厂污泥掺烧技术的未来发展方向。

Progress on Research and Technology of Sludge Blending Combustion in Coal-fired Power Plants

With the acceleration of urbanization in China,the amount of urban sewage has increased dramatically.Sludge,as a subsidiary product after sewage treatment,has a great impact on the environment.Therefore,the reduction,harmlessness,and resource treatment of sludge are imminent.Blending of sludge from coal-fired power plants is a way of the sludge disposal to achieve maximum volume reduction.In developed countries and regions,the sludge blending process has gradually matured and is more widely used in coal-fired power plants.This article reviews the current status of sludge blending technology,analyzes the impact of sludge blending technology in coal-fired power plants,and discusses the future development direction of sludge blending technology in coal-fired power plants.
