摘　　要：首先分析现有污泥处理处置技术的局限性,从土地利用、热能利用和建材利用角度分析了污泥可能的资源化途径.依据脱水污泥、干化污泥和污泥焚烧灰渣3种形态重点介绍了污泥建材利用方面的进展,同时分析了污泥建材利用的难点和问题,认为直接利用脱水污泥与页岩、粉煤灰等混合烧制烧土制品是污泥建材利用最为可行的技术途径,但需注意烧制过程中污泥重金属和气味挥发污染的控制以及混合工艺技术的改进.Utilization of municipal sewage sludge as building materials is one of the practical cost effective recycling ways.Firstly,the limitation of processing and disposal of sewage sludge with high moisture content was reviewed,and the possibilities of utilization of sewage sludge as fertilizer,fuel and building materials were introduced.Regarding dewatered,dried and incinerated states of sewage sludge,the progresses,difficulties and problems in utilization of sewage sludge as building materials were analyzed.It is a practical technology to mix the dewatered sewage sludge with shale or fly ash and fire the mixture into products,but there exist a lot of works to control the volatilization of heavy metals and odour,and to improve the mixing process in the future.
