The start-up, the characteristics of granular sludge and the treatment effect of an upflow anaerobic sludge blanket (UASB) reactor under mid-temperature were studied with high concentration carboxymethyl cellulose (CMC) wastewater as treating object. Experiment results showed that it spent 80 days to start up UASB by gradually increasing the influent CMC concentration, and the seed sludge was the mixture of the inoculum granular sludge and the digestion sludge. The removal rate of COD could reach above 80% when the value of influent COD concentration was 4000 mg/L and the organic loading was 6.86 kg/(m3 x d), respectively; granular sludge has been obtained in the reactor, and the specific methanogenic activity of the granular sludge was well.
以高浓度羧甲基纤维素（CMC）废水为处理对象，研究了中温条件下上流式厌氧污泥床（UASB）反应器的启动、颗粒污泥特性及处理效果。实验结果表明，通过逐步提高进水CMC浓度，UASB启动历时80天，接种污泥为接种颗粒污泥与消化污泥的混合污泥。当进水COD浓度为4000mg/L、有机负荷为6.86kg/(m³·d)时，COD去除率可达80%以上；反应器内已形成颗粒污泥，且颗粒污泥的比产甲烷活性良好。
