摘要
介绍了以水产品加工废水为主要原水的某污水处理厂控制污泥膨胀的情况。经过分析认为污泥负荷的增大是造成该污水处理厂污泥膨胀的主要原因 ,并采取了提高污泥回流比、降低污泥排放量、加大曝气量、加强指标监控等措施 ,从而有效地控制了污泥膨胀问题。
It is believed that the excessive high level of sludge loading has caused activated sludge bulking in a fishery processing wastewater treatment system. The countermeasures against sludge bulking such as the increasing of sludge recycle ratio, reducing of sludge discharge, intensive air aeration, monitoring the operation parameters and so on, are presented. These measures have controlled the sludge bulking effectively.
