摘　　要：针对制浆造纸工业废水处理中污泥的性质指标及常规处置方法的状况,介绍了机械半干化污泥焚烧处置技术,主要包括污泥一级脱水处理的系统工艺路线及主要设备,污泥二级处理的干化焚烧系统装置及技术特性,并对该工艺运行费用、社会环境效益进行了分析和总结。通过各个行业的生产应用,以两级处理为主线的污泥处理工艺,具有工艺合理、运行成本低、系统操作弹性大、处理能力大、系统装置投资小、二次污染小等特点,在造纸废水处理中的污泥处置领域前景广阔。According to the situation of sludge parameters in pulp ＆ paper waste water treatment, the sludge treating process and common treating way. half dry mechanical sludge incineration technology was introduced including the process and main equipment for primary treatment of sludge, the dry incinerating facilities and their technical features for sludge secondary treatment. The operating cost, social and environmental benefits were analyzed and summarized. The practical application has proved that the two stage sludge treating process have the advantages of reasonable process design, low operating cost, being simple in operating, larger treating capacity, lower investment for system equipment, small secondary pollution, etc., with a good perspective for the sludge treatment of waste water treating area in paper industry.
