Abstract:

为探讨累积在MBR中的SMP浓度变化对生物除磷的影响，制备了不同SMP含量的污泥样品进行生物除磷间歇试验，研究SMP含量对污泥除磷能力的影响.结果表明，SMP含量较高的污泥样品具有较高的好氧吸磷速率，达0.20mg-P·（g-MLSS）-1·min-1，并在MBR脱氮除磷工艺长期运行过程中，保持较高的好氧吸磷速率.对污泥吸磷和释磷过程中上清液组成变化的研究发现，在好氧条件下，存在水相中SMP向污泥相转移的过程.根据这一过程中Zeta电位绝对值的减小推测，上清液中的胶体可能逐步失稳而向污泥相转移，胶体磷由此进入污泥相；此过程可能伴随着对自由磷酸盐的捕集和卷扫，从而促进了污泥的好氧吸磷.
