UBF工艺处理废纸浆造纸废水

Treatment of waste-paper pulp effluent by process of UBF

对上流式厌氧污泥床过滤器UBF(Upflow Blanket Fil-ter)工艺处理废纸浆造纸废水进行了实验研究。实验表明,UBF反应器经过三个月达到稳定运行,培养出适合水质要求的厌氧污泥,运行结果表明,在进水CODCr为1800mg/L左右的条件下,出水CODCr一般在600～700mg/L,平均去除率稳定在65.7%左右。

Upflow anaerobic sludge bed filter UBF （Upflow Blanket Filter） process for the treatment of effluent from paper mills with waste paper as raw materials was studied with experiments. The experiments indicate that anaerobic sludge of the quality suitable for the requirements is cultivated after three months stable tion for the UBF reactor. The operating result showes that opera- under the condition of the influent CODcr of about 1800mg/L, the effluent CODcr is normally between 600-700mg/L with the average removal rate at around 65.7%.
