摘要: 污泥运输可为污泥处理处置其他环节稳定、高效的运行提供保障。在污泥运输的众多方式中,管道输送污泥相对于传统的汽车输送污泥具有密闭、安全和高效等特点,成为污泥运输行业研究的焦点。在设计污泥管道输送系统时,计算运送污泥所需的管道压力尤为重要,但是管道压力的计算容易受到污泥流变特性的影响。首先介绍了温度、含水率、pH值及剪切速率等参数对污泥流变特性的影响;总结了含水率>90%的污泥与含水率在60%~90%的污泥管道输送研究现状,并分析了污泥管道输送的能耗与成本,管道输送适用于城市中心地区地下污水处理厂污泥处理处置的输送;并指出通过改进污泥在管道内的输送方式、改善污泥的流动特性等措施来提高污泥管道输送效率及降低管道输送运行维护费用。Abstract: The transportation of sludge ensures the stable and efficient operation of other links of sludge treatment and disposal.In many ways of sludge transportation,pipeline transportation of sludge is closed,safer and more efficient compared with the traditional truck transportation,which has become the research focus of sludge transportation industry.In the design of sludge pipeline transportation system,it is very important to calculate the pipeline pressure required for transporting sludge,but the calculation of pipeline pressure is easily affected by the rheological characteristics of sludge.This paper first introduces the influencing factors of sludge rheological characteristics such as temperature,moisture content,pH value and shear rate of sludge.Secondly,the research status of pipeline transportation of sludge with moisture content higher than 90% and sludge with moisture content of 60%~90% is summarized,the energy consumption and cost of sludge pipeline transportation are also analyzed.The pipeline transportation was applicable to the transportation of sludge treatment and disposal of underground sewage treatment plants in urban central areas.Finally,methods of improving the transportation mode of sludge in the pipeline and flow characteristics of the sludge are expounded to improve the transportation efficiency of sludge pipeline and reduce the operation and maintenance cost of pipeline transportation.
