摘　　要：亚麻废水是一种较难降解的有机废水 ,用单一的好氧生物法处理效果不好。采用水解酸化 气浮 SBR工艺处理亚麻废水 ,设计处理能力 10 0 0m3/d ,设计废水水质为 :COD 80 0～ 10 0 0mg/L ,BOD 4 0 0～ 5 0 0mg/L ,SS 2 0 0～ 30 0mg/L ,pH 7。在保证酸化水解调节池正常运行的条件下 ,COD去除率可达 2 5 %以上 ,再经气浮及SBR处理 ,COD去除率可达 85 % 。The aerobic biological treatment of linen wastewater seems poorly, because the organic matters in the wastewater is not easy to degrade. A facility with capacity of 1 000 m 3/d and using a combined processes of hydrolysis acidification, air floatation and SBR was designed. The designed inflow has strengthenings as COD=800～1 000 mg/L , BOD=400～500 mg/L, SS=200～300 mg/L and pH=7. When normal operation of hydrolysis acidification was guaranteed, COD removal over 25% could be reached. Afer airfloatation and SBR process the final COD removal would be 85%. The effluent could meet the national integrated wastewater discharge standard GB 8978-96.
