摘要采用两个实验室厌氧-好氧活性污泥反应器进行强化生物除磷研究。它们仅在有机基质组成上不同。向反应器F进料乙酸盐，向反应器G进料乙酸盐-葡萄糖混合物。两个反应器均以具有增强的生物除磷能力的相同活性污泥启动。在适应期间，这种能力在反应器F中增加了几倍，但在反应器G中完全丧失。尽管如此，在反应器G的厌氧阶段，有机底物也从溶液中消失。由于电子受体如溶解氧，硝酸盐，亚硝酸盐，硫酸盐等的干扰太低，无法解释这一现象。
Abstract Two laboratory anaerobic‐aerobic activated sludge reactors were operated to study enhanced biological phosphate removal. They differed only in organic substrate composition. Reactor F was fed with acetate, reactor G with an acetate‐glucose mixture. Both reactors were started with identical activated sludge which had an enhanced biological phosphate removal ability. During the adaptation period this ability increased several fold in reactor F but it was completely lost in reactor G. In spite of this fact, organic substrate also disappeared from the solution during anaerobic stage in reactor G. Interferences due to electron acceptors such as dissolved oxygen, nitrates, nitrites, sulphates etc. were too low to explain this phenomenon.
