| 摘 要： | 在前期已进行的污泥负荷对丝状菌污泥膨胀影响的研究基础上。对低污泥负荷下发生的污泥膨胀进行了污泥沉降性能恢复的试验研究。结果表明，恢复高污泥负荷运行能使膨胀污泥的沉降性能得以恢复，而恢复时间及恢复速率与膨胀程度均呈正相关关系；溶解氧是影响膨胀污泥沉降性能恢复的重要因素，在溶解氧不足时提高污泥负荷不但不能使污泥膨胀得到控制。反而却加剧了污泥膨胀。

| Abstract: | Study was made previously on the effect of sludge load on filamentous sludge bulking, based on which experimental study was then conducted on the recovery of settleability of bulking sludge happening at low sludge load operation. The result showed that resuming of high rate operation can result in the recovery of bulking sludge settleability, and recovery time and rate are in positive correlation with bulking level. Dissolved oxygen is an important factor affecting the recovery of bulking sludge settleability. When dissolved oxygen is inadequate, improvement of sludge load will not only fail to bring the sludge bulking under control, but also aggravate sludge bulking. |
