摘　　要：采用UASB 接触氧化工艺对亚麻沤制废水进行了试验研究 ,结果表明 :COD去除率可达 95 %～ 97% ,BOD5去除率为 96 %～ 99%。生物难降解的单宁、木素类物质去除率为 75 %～ 86 %。对单宁。The experimental study on treatment of retting flax wastewater by UASB contact oxidation had been conducted. The result proved that the removal rates of COD and BOD 5 were up to 95%～97% and 96%～99% respectively. The removal rate of ligin which were hard to be degraded by microorganism was 75%～86%. The biochemical special properties and degrading mechanism of lignin were systemally analyzed and explicated.
