| 摘 要： | 采用一体式膜生物反应器处理城市污水，考察了污泥浓度的变化、系统对有机物和氨氮的去除效果以及温度对氨氮去除效果的影响。结果表明，在试验初始阶段，MLVSS和MLSS均随时间的延长而增加，培养25d后MLVSS基本稳定在2500mg／L左右，而MLSS则继续增加，系统稳定运行后，MLSS维持在4000mg／L左右；对COD和NH3-N的去除率分别为85％左右、36．7％～96．7％；对NH3-N的去除效果受温度影响较大，当温度〈15℃时，温度逐渐成为去除NH3-N的制约因素。 |

| Abstract: | Submerged membrane bioreactor was used to treat municipal sewage.The variation of sludge concentration,the removal efficiencies of organic matters and NH3-N and the effect of temperature on the NH3-N removal were investigated.The results show that both MLVSS and MLSS increase with time during the initial stage.After 25 d of culture,MLVSS is kept at about 2 500 mg/L while MLSS continues to increase and is kept at about 4 000 mg/L during the stable operation period.The removal rates of COD and NH3-N are 85% a... |
