改进UASB厌氧反应器布水器的创新实践

Innovation Practice of Distributor in UASB

垃圾渗滤液、屠宰废水等高浓度废水处理领域广泛使用升流式厌氧污泥床反应器(UASB)。在工程实践中,对UASB厌氧反应器的布水器进行了创新性改进,将上进水、下布水的一管一点式布水改为下进水、下布水的分级式布水,并取得了成功。

Up-flow anaerobic sludge blanket concentration wastewaters, such as landfill leachate, （UASB） reactor is widely used in treatment of high abattoir wastewater and so on. In practice, the dis- tributor in UASB was modified from ＂one-tube-one-point distribution with top-in and bottom-out＂ to ＂multi-step distribution with bottom-in and bottom-out＂, and the modification was proved to be effective.
