This work presents preliminary results for distillery wastewater treatment in a MBR equipped with filters prepared from waste fly ash. The system was fabricated locally and employed submerged membranes in the 2-8 microm pore-size range. Distillery wastewater, after anaerobic digestion, was used as the feed and the bioreactor was inoculated with sludge obtained from a local distillery unit. The MBR was operated for around 250 days. The wastewater quality was monitored in terms of COD (chemical oxygen demand), colour, phenol, and MLSS (mixed liquor suspended solids) concentration. An average COD and phenol removal of 36% and 60% respectively was obtained. The maximum suspended solids retention by the ash filter was as high as 98%. The results were encouraging and further trials are currently underway to improve the performance.
这项工作展示了在配备由废弃粉煤灰制备的过滤器的膜生物反应器中处理酿酒厂废水的初步结果。该系统是在当地制造的，采用了孔径范围为2 - 8微米的浸没式膜。经过厌氧消化后的酿酒厂废水用作进料，生物反应器接种了从当地酿酒厂单元获得的污泥。该膜生物反应器运行了约250天。从化学需氧量（COD）、颜色、苯酚和混合液悬浮固体（MLSS）浓度方面对废水质量进行了监测。分别获得了平均36%的COD去除率和60%的苯酚去除率。灰分过滤器对悬浮固体的最大截留率高达98%。结果令人鼓舞，目前正在进行进一步试验以提高性能。
