NOVELTY - A biological enzyme hydrolysis acidification device has a low dirt anoxic zone (5) connected with a bio-enzyme reacting region (1), an aerobic area (2), a high dirt anoxic zone (3) and a sewage anoxic zone (4). An aeration system (8) is placed at a bottom part of a settling tank. The sewage anoxic zone and the low dirt anoxic zone are provided with the aerating system and an anoxic zone filling material. A sludge acidification tank (7) is provided with the aeration system and connected with the bio-enzyme reacting region and the low dirt anoxic zone through a return pipe (11).    USE - Biological enzyme hydrolysis acidification device for processing sewage and waste water.    ADVANTAGE - The device can increase number of microorganisms, and can improve microorganism quality and effectiveness of hydrolysis of acidification persistent organics.    DETAILED DESCRIPTION - A biological enzyme hydrolysis acidification device has a high dirt anoxic zone utilized for dividing oxygen and high concentration dirt. A low dirt anoxic zone is connected with a bio-enzyme reacting region, an aerobic area, the high dirt anoxic zone and a sewage anoxic zone. The bio-enzyme reacting region is provided with a water inlet channel and a water inlet rectification plate, where the water inlet channel is arranged on a water inlet in the bio-enzyme reacting region. The water inlet rectification plate is installed on the bio-enzyme reacting region closed to the water inlet channel. An end of the bio-enzyme reacting region is connected to a side wall of an upper part of the aerobic area. An aeration system is placed at a bottom part of a settling tank. An aerobic region filler is arranged on the aeration system and the high dirt anoxic zone. The sewage anoxic zone and the low dirt anoxic zone are provided with the aerating system and an anoxic zone filling material. A sludge acidification tank is provided with the aeration system and connected with the bio-enzyme reacting region and the low dirt anoxic zone through a return pipe.
