摘　　要：研究了不同浓度乙酸盐和不同基质的有机碳源对序批式生物膜法生物除磷的影响以及磷的厌氧释放量和好氧吸收量之间的关系。结果表明 ,为获得稳定良好的生物除磷效果 ,厌氧时间必须保证生物易降解有机物在厌氧过程基本去除 ,同时COD负荷也不能太低 ,还要满足反应器中生物量能够实现净增长。研究认为乙酸盐能够较好地刺激聚磷菌厌氧释磷达到过量生物除磷 ,磷的厌氧释放量和好氧吸收量具有良好的相关性 ,为提高除磷效率必须保证足够的厌氧磷释放量。The effect of different concentration of acetate and different substrate as organic carbon on biological phosphorus removal in the sequencing batch biofilm reactor was studied. The relation of aerobic phosphate removal versus anaerobic phosphate release was analyzed. The results indicate that in order to achieve good and stable phosphorus removal over time, the length of the anaerobic period should be changed to achieve complete removal of easily biodegradable COD in the anaerobic period. The total COD-loading rate should be kept high enough to achieve a net growth of biomass in the reactor. Aerobic phosphate removal versus anaerobic phosphate release has good relativity. In order to enhance phosphorus removal the enough anaerobic phosphate release should be guaranteed.
