The invention provides an
anaerobic aerobic flocculation sedimentation sewage treatment process, which comprises the following steps: the
sewage first passes through the grille and the
water collection well, then enters the swirl type grit chamber through a water pump, and then flows into the anaerobic membrane
bed for anaerobic biological treatment. The
sewage after
anaerobic treatment flows into the biological aerated filter for aerobic biological treatment. After aerobic treatment, it enters the
flocculation reaction and settles before being discharged. The present invention takes anaerobic membrane
bed and biological aerated filter as the main body, supplemented by
flocculation and
sedimentation, has
fast start-up, stable operation, short
hydraulic retention time, high efficiency, simple process flow, and convenient operation and implementation; the equipment is compact in structure and occupies an area Small area, less investment than infrastructure construction, low
operating cost,
low noise, no peculiar smell, and no
impact on the surrounding environment during operation. It can be applied to urban domestic sewage, restaurants,
living quarters, military barracks, factories and hospitals. treatment, and has broad application prospects.
