Abstract

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.
