  • Patent number: 11472725
    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.

  • Publication number: 20220321971
    Abstract: A machine detects a set of first control operations and, in response, causes a display screen to present a graphical interface in which a central window suggests first content by presenting a first preview and a first identifier superimposed on the first preview. The machine then detects a second control operation that indicates dismissal of the first content. In response to the second control operation, the machine causes the display screen to present a transition to an interest-improved version of the graphical interface. The transition includes sliding the first preview, the first identifier, a second preview, and a second identifier together in a shared direction and at a shared speed within the central window. The second preview and the second identifier correspond to second content. In the interest-improved version of the graphical interface, the central window suggests the second content by presenting the second preview and the second identifier.
