| 摘 要： | 采用常温上流式厌氧污泥床(UASB)反应器降解冬瓜加工废水,研究了厌氧颗粒污泥处理冬瓜食品加工废水的处理效果。试验结果表明,当水力停留时间(HRT)为24 h,冬瓜废水进水COD_(Cr)浓度约为10 000mg/L时,相应的容积负荷为10.0 gCOD/(L·d),COD去除率可达97%以上。当容积负荷约为6.0 gCOD/(L·d)时,出水COD_(Cr)可达100 mg/L以下,达到《污水综合排放标准》(GB 8978-1996)一级排放标准的要求。

| Abstract: | Upflow anaerobic sludge blanket （UASB） reactor was used for degradation of white gourd food processing wastewater, and the treatment effect of white gourd food processing wastewater by anaerobic granular sludge was studied. The results show that the COD removal rate could reach over 97 % when hydraulic retention time （HRT） is 24 h, COD volume load is 10.0 g/ （L·d）, and influent CODa in UASB reactor is about 10 000 mg/L. The effluent CODe, could reach lower than 100 mg/L when the COD volume load is about 6.0 g/（L·d）, which meets the first level criteria specified in Integrated Wastewater Discharge Standard （GB 8978-1996）. |
