机械搅拌UASB反应器处理高浓度有机废水的研究

Study on the High COD Concentration Organic Wastewater treatment by the Machinery Stirring UASB Reactor

本文以实验为根据,论述了机械搅拌UASB反应器处理高浓度有机废水的成功启动过程。本实验在去除率达到50%后提高负荷,每次提高负荷的幅度为前次负荷的20～30%。实验历时60天,COD负荷达到10.88kg/(m3?d)时去除率达到70%,大大缩短了启动时间。

The paper based on experiments, describes, the start-up process of the machinery stirring UASB reactor handling the high COD concentration organic wastewater. This experiment raises the volumetric loading when COD removal was achieved above 50% and the range of raising the loading is 20～30% of the last loading. During 60d, the reactor presented COD removal was achieved above 70% when the volumetric loading was 10.88 kgCOD/(m3?d).
