| 中文摘要 |
| 对自行研制的上流式多级厌氧反应器（UMAR）处理木薯淀粉废水的启动和运行特性进行了研究.结果表明，UMAR反应器启动周期短，易培养出活性高的颗粒污泥，经过40 d的运行，COD去除率可达84%，VSS/TSS由78%增加到90.4%.UMAR处理效率高，水力停留时间（HRT）为4 h，进水COD为6 250 mg/L，容积负荷为24 kg/(m3·d)时， COD去除率在75%以上.UMAR反应器对负荷提高、低pH冲击、进水水质的改变表现出良好的耐受能力. |

| The performance and the characteristics of a laboratory scale up-flow multistage anaerobic reactor (UMAR) were investigated using cassava starch wastewater. The experimental results showed that the formation of anaerobic granules in UMAR system was facilitated and short period to start up. Usually, in 40 d after starting up, COD removal efficiency was kept above 84% and VSS/TSS increased from 78% to 90.4%. The UMAR reactor was high effective. Its COD removal keeps about 75% when HRT is 4 h, inflow COD concentration is 6 250 mg/L and volumetric loading is 24 kg/(m3·d).And UMAR reactor has excellent resistance to the impact of high load,low pH and variation of water quality. |
