城市污泥管道运输的探讨

对城市污泥的外运方式进行了三种运输方案的比较，管道输送具有十分明显的环境效益和节能效益。说明了污泥的流体特性和管道输送特性参数的计算方法，叙述了管道输送系统的设计要点，给出了若干污泥管道输送应用实例。

The Comparisons of three types for sewage sludge transportation have been performed. It is obvious that there are many advantages in environmental and economic benefits for pipeline transportation. There are descriptions about the calculation methods of the characteristic parameters for flowing and transportation of sewage sludge. The design key points and some examples of pipeline transportation of sewage sludge are introduced.
