  • Publication number: 20210130205
    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: 20210130210
    Abstract: The present invention relates to microbial carriers for wastewater treatment, and in particular, relates to an organic composite powder carrier and its application for strengthening biological denitrification in municipal wastewater treatment. The organic composite powder carrier is compounded by a microbial carrier with a relatively large equivalent particle size and an organic alternative carbon source in the form of ultrafine powder. The composite powder carrier in the present invention includes a dedicated organic alternative carbon source, such as polyhydroxyalkanoates (PHA). The organic alternative carbon source can exclude the competitive relationship between microorganisms to ensure that denitrifying bacteria exclusively obtain electron donors required for denitrification.
