The invention discloses a jet aeration biological reaction system. The system comprises an aeration bioreactor, a water collecting tank, a secondary sedimentation tank, a water pump and a water ejector. An aeration pipe is arranged in the aeration bioreactor. One end of the water pump is connected to the lower end of the water collecting tank, and the other end of the water pump is connected to the water ejector by a pipeline. The rear end of the water ejector is connected to the aeration pipe by a pipeline. The bottom end of the aeration bioreactor is connected to a return sludge pipe. A filter cylinder is arranged in the middle of the secondary sedimentation tank. One side of the aeration bioreactor is connected to the filter cylinder by a water outlet pipe. The lower end of the secondary sedimentation tank is connected to the upper end of the water collecting tank by a return pipe. The upper end of the water collecting tank is connected to a wastewater pipe. An air pipe is arranged at the upper end of the water ejector. The water collecting tank is arranged at the upper end of the secondary sedimentation tank. One side of the water collecting tank is connected to a water drainage pipe. The system is advantaged by high aeration pressure, good stirring and mixing effects, high oxygen transfer rate and small floor area.
Description
technical field [0001] The invention relates to a jet aeration biological reaction system, which belongs to the field of water treatment. Background technique [0002] At present, the treatment of medium and low concentration organic wastewater has been treated by aerobic activated sludge method, the aeration method mostly adopts blast aeration or mechanical aeration, and the reactor mostly adopts rectangular or circular aeration tank. Aerobic biological treatment uses the metabolic process of microorganisms to degrade the organic matter in wastewater into CO through a series of biochemical reactions. 2 、H 2 O and other inorganic substances, so that the wastewater can be purified. The oxygen required by microorganisms in the metabolic process of degrading organic matter is supplied by aeration. The traditional air supply methods include blast aeration and surface aeration. These aeration methods need to use blowers and air intake pumps to press air into the bioreactor. T...
