摘  要:
UASB反应器高度优化设计对UASB启动、运行尤为重要,本文根据UASB反应器内紊流扩散概念,推得UASB反应器内污泥悬浮层沿垂直高度的污泥分布模型,通过小试实验数据经计算机模拟,可以取得UASB优化设计参数。

摘  要:
The height is an important factor of UASB reactor for design, especially for starting up and operation of the reactor. In this paper, a model of the vertical distribution of sludge depending on the height within sludge blanket of UASB reactor was obtained by simulation based on the turbulent diffusion concepts. The data from laboratory experiment were fitted with the model by computer. They can be used as optimal parameters for design of UASB reactors.
