  • Publication number: 20200207650
    Abstract: Disclosed is a sequencing batch reactor (SBR) for sewage treatment. The SBR is applicable to an energy-producing sewage treatment system. The SBR includes a treatment tank and a hybrid bacterial strain screening tank. The treatment tank removes ammonium contained in supernatant liquid using anaerobic ammonium-oxidizing (anammox) bacteria. The hybrid bacterial strain screening tank screen anammox bacteria granules out by passing the supernatant liquid discharged from the treatment tank through the hybrid bacterial strain screening tank. The SBR generates biogas using the anammox bacteria and reduces the nitrogen content in the supernatant liquid. The SBR can separate the anammox bacteria granules with high separation efficiency, thereby shortening sewage treatment time and recycling activated sludge, resulting in a dramatic decrease in the amount of waste sludge.
