【摘要】 亚麻沤制废水属于高浓度有机废水。该废水有机物浓度COD为4000—10000mg/l,BOD₅为2000—6000mg/l,木质素为130—260mg/l。本文采用上向流厌氧污泥床作为该废水的主要处理工艺,取得了很好的效果。COD的去除率可达到78.1％～95.2％,BOD₅的去除率可达到90.2％～98.7％,木质素的去除率可达到12.5％～51.9％.为后续的好氧处理出水达到国家排放标准,奠定了很好的基础.更多还原

【Abstract】 Treatment of flax retting waster has all long been a difficult topic. It has a high organic content. The COD、BOD5and light concentrations are in the range of 4000-10000 mg/l、 2000 - 6000mg/l、 respectively. Treated by the process of anaerobic COD in effluent will be 432. 92 - 992. 00mg/l、 BOD5 106. 92 - 440. 20mg/l and the removal rate will be 78. 1% -95. 2%,90. 2%-98. 7% respectively.更多还原
