低温下迅速恢复曝气池污泥活性的方法

Method research on quickly recovery of aeration tank sludge activity under cryogenic conditions

在中国北方天气寒冷、水温较低的情况下,通过投加蒸汽和碳、氮、磷等营养,用10d左右时间迅速恢复了曝气池污泥的活性。可为类似企业提供借鉴。

This paper provided reference to similar enterprises. By adding steam and carbon, nitrogen, phosphorus and other nu- trients, the aeration tank sludge activity can be quickly restorcd within 10 days under cryogenic condition in the cold weather of northern China.
