| 摘 要： | 用12 5mL血清瓶作为批量处理反应器,对厌氧颗粒污泥和消化污泥在厌氧和微氧条件下的COD去除率、污泥产率、产甲烷活性、抗冲击负荷能力等进行对比实验研究。实验结果表明:厌氧颗粒污泥和消化污泥均在微氧条件下表现出高COD去除率、低污泥产率、高产甲烷活性和强抗冲击负荷能力,且厌氧颗粒污泥在COD去除率、污泥产率、产甲烷活性和抗冲击负荷等方面更具有优势;对于0 5 gCOD/LR·d的有机负荷,反应器内最佳加氧量为10mL(10 %添加的COD)。

| Abstract: | Using 125 mL serum bottle as batch reactors, the COD removal efficiency, biomass production rate, methanogenic activity and supporting shock load of anaerobic granular sludge and digestion sludge were assayed under anaerobic and microaerobic conditions. The results showed that both of the anaerobic granular sludge and digestion sludge had high COD removal efficiency, low biomass production rate, high methanogenic activity and better supporting shock load under microaerobic conditions. Moreover, the anaerobic granular sludge had apparent advantage. The optimal supplement of oxygen was 10% of the adding COD. |
