This invention discloses a highly efficient integrated anaerobic ammonia oxidation reactor and treatment method for kitchen wastewater sludge, belonging to the field of wastewater treatment technology. The reactor includes a tank and integrated pretreatment module, denitrification reaction module, solid-liquid separation module, temperature control module, aeration module, and sludge circulation module. The pretreatment module is located at the bottom of the tank and includes a grid filter unit and a bio-adsorption unit; the denitrification reaction module is located above the pretreatment module and is filled with granular anaerobic ammonia oxidation composite bacteria; the solid-liquid separation module is located above the denitrification reaction module and includes a three-phase separator and an inclined plate sedimentation unit. This invention, through its integrated design, achieves pretreatment, denitrification reaction, solid-liquid separation, and precise control within a single tank, solving the problems of low integration, easy loss of bacteria, and high operating costs in existing technologies. It has advantages such as small footprint, high efficiency, stable operation, and no need for external carbon sources, making it particularly suitable for kitchen wastewater sludge treatment.

This utility model relates to a combined integrated wastewater deep treatment equipment, comprising: an anaerobic tank, effluent from the anaerobic tank being connected to an anoxic tank, effluent from the anoxic tank being connected to an aerobic tank, a suspended sedimentation separation structure within the aerobic tank, an aeration device below the sedimentation separation structure within the aerobic tank, supernatant from the sedimentation separation structure being connected to a vertical flow sedimentation tank, supernatant from the vertical flow sedimentation tank being connected to a gradient filtration device, and effluent from the gradient filtration device being connected to a clear water tank. The beneficial effects are: the proportion and sequence of anaerobic, anoxic, and aerobic processes can be adjusted according to different usage scenarios; the process is arranged in the order of anaerobic, anoxic, and aerobic, mainly for simultaneous nitrogen and phosphorus removal; the biological treatment zone consists of anaerobic + anoxic + aerobic; and the sedimentation zone and gradient filtration are connected in series at the end of the biological treatment zone, highly integrating biological and deep treatment processes, resulting in equipment with high treatment efficiency, high flexibility, strong adaptability, low operation and maintenance difficulty, and low operating energy consumption.
