【摘要】 本文研究了啤酒厂麦芽汁废水稀释液(COD约2000mg/L)常温(25℃)两相UASB工艺的运行性能。结果表明:该工艺具有很好的处理效果,负荷可达18kg COD/m~3·d,相应水力停留时间2.7h,溶解性COD去除率86％(以产甲烷相计),本文还对产酸相、产甲烷相的运行及颗粒污泥的性质作了系统研究。更多还原

【Abstract】 Perfor mance of ambient (25℃) two-phase UASB process treating malting wastewater (diluted to 2000 mgCOD/L has been investigated. It is shown that this process has a high treatability with organic loading rate of 18 kgCOD/m3·d, HRT of 2.7 h and soluble COD res moval of 86% on a methane phase base. A systematic research is also done on the performance of acid- and methane-phase reactors and property of granules.更多还原
