Abstract
A recovery system of composite powder carrier in HPB municipal wastewater treatment includes a biochemical tank and a concentration tank. The composite powder carrier is added to the biochemical tank for biochemically treating on the wastewater. The mixed liquid is then made to flow into the concentration tank. The supernatant obtained after filtration is then discharged. The concentrated sludge is returned to the biochemical tank, and the excess concentrated sludge is transported to a separator. The separator separates the substances with large specific gravity from those having smaller specific gravity, and the substances with large specific gravity are recycled to the biochemical tank for reuse. Matter having smaller specific gravity is discharged. The separator can be used to separate the composite powder carriers for recycling, which improves the utilization rate of the composite powder carriers and reduces the operation cost of the HPB technology for wastewater treatment.
