UASB反应器常温下处理生活污水的中试研究

Pilot Scale Study on Low Strength Wastewater Treated by UASB Reactor at Normal Temperature

中试试验研究讨论了利用颗粒污泥接种的UASB反应器常温下处理生活污水的运行性能。在7～31℃温度范围内处理生活污水,考察了不同温度、不同负荷条件下反应器的处理效率,讨论了各参数对反应器运行的影响,为UASB反应器常温下处理生活污水提供理论和实践指导。

A pilot scale study was performed to deal with low strength wastewater with USAB reactor with mature granule sludge as seed sludge. The experiment was operated at a temperature range varying from 7~31℃, and disposal efficiency of reactor at different temperature and different loading rate was studied. Some parameters that had a great impact on the reactor operation were also discussed, which will provide technical guidance for UASB reactor dealing with domestic wastewater.
