| 中文摘要 |
| 采用上流式厌氧污泥床(UASB)反应器，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UASB反应器的启动、颗粒污泥特性和废水处理效果.结果表明，采用接种颗粒污泥与消化污泥的混合泥进行培养，并逐步提高进水CMC废水浓度，运行80 d后，可实现UASB反应器的启动；当进水COD值达到4 000 mg/Ｌ，容积负荷6.86 kg/(m3·d)，COD去除率在80%以上；反应器内污泥实现颗粒化，且颗粒污泥的比产甲烷活性良好. |
| 英文摘要 |
| 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 4 000 mg/Ｌ and the organic loading was 6.86 kg/(m3·d),respectively; granular sludge has been obtained in the reactor, and the specific methanogenic activity of the granular sludge was well. |
