摘要
简述了我国污泥处置面临的问题,结合国内外污泥处置情况,总结几种主要的城市污泥处理处置技术,如卫生填埋、焚烧和土地利用等的应用特点及限制条件,为因地制宜地寻找经济有效的污泥处理处置技术提供指导。利用污泥资源化技术,制作污泥吸附剂、建材、污泥低温热解制油等,这些技术的研究进展和应用前景将是今后污泥处置的发展方向。
The issues about sludge disposal in China are discussed in this paper firstly.Combined with sludge disposal conditions at home and abroad,the application characteristics and limited conditions of several main technologies including sanitary landfill,burning and land utilization,etc.are summarized,which may provide guide for choosing economic & effective sludge disposal technology based on local conditions.Through sludge resource utilization technology,sludge adsorbent,construction material and oil from low temperature pyrolysis can be completed and their research development and application prospect will be the developing direction of sludge disposal.
