摘　　要：针对木材蒸煮废水含有高木质素和可生化性差的特点,本工程采用气浮-酸化水解-MBR组合工艺对木材蒸煮废水与生活污水的混合废水进行处理(混合比1∶1)。在日处理量为80m3的稳定运行工况下,出水水质达到国家《生活杂用水水质标准》(GJ/T48-1999),并被回用于厂内蒸煮工艺用水,部分回用于厂区绿化、冲厕等。The process of air floatation-hydrolysis acidification-MBR was used for mixed treatment of domestic sewage and waste water from cooking wood(mixing rate was 1∶1).The waste water features high content of lignin and poor biodegradation and so on.Under the stable condition of day treating capacity of 80 m3,the effluent water reaches the discharging standards of domestic water(GJ/T48-1999)and can be directly used in cooking process and part of it used in greening around the plant and flushing toilet.
