上流式污泥床过滤器处理生物质气化发电焦油废水——厌氧污泥驯化和颗粒化研究

Acclimation and Granulation of Anaerobic Sludge in UBF Reactor Treating Tar-containing Wastewater from Gasification of Biomass for Power Production

处理生物质气化发电焦油废水的上流式污泥床过滤器(UBF)内厌氧污泥在环境温度(16～36℃)条件下完成驯化并实现颗粒化,其间焦油废水的COD比例是主要影响因素。UBF反应器稳定运行时,在HRT为66 9h,OLR为0 65～0 75kgCOD·m-3d-1的条件下,焦油废水COD平均去除率达到26%。

Acclimation and granulation of anaerobic sludge was achieved in the UBF reactor treating tar containing wastewater from gasification of biomass for power production at ambient temperature (16～36℃), the COD proportion of tar containing wastewater in the influent was the main effect factors in the process . Under stable operation condition , the average removal of COD was 26% in the UBF reactor with HRT of 66 9 h and OLR of 0 65～0 75 kgCOD·m 3 d 1 .
