【摘要】 对中试规模的缺氧—好氧—膜生物反应器(A/O—MBR)处理城市污水进行研究,并对好氧池内活性污泥的特性和膜污染后期的影响因素进行了分析。试验结果表明:污泥浓度(MLSS)对CODCr、氨氮等各指标的处理效果均有影响。与传统活性污泥工艺相比,膜生物反应器污泥负荷小、表观产泥率低。更多还原

【Abstract】 A pilot-scale anoxic/oxic membrane bioreactor （A/O—MBR） was applied for municipal wastewater treatment. Researches on activated sludge characters in oxic section and the influencing factors of membrane fouling were carried out. The results show that sludge concentration influences in various degrees on removal efficiency of COD Cr and NH₃-N etc. Compared with traditional activated sludge process, the sludge loading and apparent sludge yield of this system were lower.更多还原
