摘　　要：通过对停止运行8个月的UASB反应器进行二次启动试验,重点分析了用于低浓度生活污水处理的UASB反应器的二次启动的影响因素.研究结果表明,可直接利用反应器内原有颗粒污泥进行二次启动;二次启动期间,水力负荷是重要的运行控制参数,并应避免活性厌氧污泥流失.反应器稳定运行后,CODCr、CODf的去除率均能达到50%,SS去除率可以达到80%以上.Based on the experiment on the secondary start-up of the UASB reactor that had stopped working 8 months, this study mainly explored the affecting factors of the secondary start-up of the UASB reactor employed in the low-concentration domestic wastewater. The results showed that the remaining granular sludge in the reactor could be directly utilized for the secondary start-up of the UASB reactor. The hydraulic load should be taken as the controlling parameter during the period of secondary start-up in order to avoid washing away active anaerobic sludge. After the secondary start-up was completed, the removal efficiencies of CODcr and CODf could be up to 50%, and over 80% of SS removal efficiency could be achieved.
