Composite UBF anaerobic organism waste water treatment reactor

The utility model discloses a compound UBF anaerobic reactor for treatment of wastewater, and belongs to the field of anaerobic wastewater treatment reactor. The reactor comprises an upright tank, a water inlet, a water outlet, and a biological packing zone. A granular sludge zone is provided at bottom of the upright tank; and a sludge suspension zone is provided above the upright tank; the biological packing zone is arranged in the middle of the upright tank; an absorption and micro-electrolysis zone is provided on the top. The water inlet is connected with the granular sludge zone; a filtration and adsorption zone is connected with the water outlet. Regarding the reactor, anaerobic granular sludge digestion, anaerobic filter, adsorption and micro-electrolytic treatment are gathered in one anaerobic reactor. The whole device is compact and simple to operate. By adopting the technology of the utility model, poisonous organic waste which contains much suspended matter, is deeply colored and difficult to be degraded is effectively treated.
