Title:
ANOXIC AND AEROBIC INTERACTIVE REACTION DEVICE AND REACTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/057125
Kind Code:
A1
Abstract:
An anoxic and aerobic interactive reaction device, comprising a tank body (1), a water intake pipe (2) connected to the bottom of the tank body (1), and a water output pipe (3) connected to the upper portion of the tank body (1). A reaction area (4), an anoxic activated sludge area (5) and an aerobic activated sludge area (6) are arranged inside the tank body (1); a partition wall (7) is arranged between the anoxic activated sludge area (5) and the aerobic activated sludge area (6); and the partition wall (7) is movably connected to a rotating plate (8) which selectively enables the reaction area (4) to be in communication with the anoxic activated sludge area (5) or enables the reaction area (4) to be in communication with the aerobic activated sludge area (6). During a carbon source capturing and adsorbing process, a nitrification process and a denitrification process, the rotating plate (8) is controlled to rotate to control the reaction device to enter different reaction processes, an original carbon source in sewage is used for performing nitrogen removal, by means of denitrification, on the nitrified sewage, and therefore, a good nitrogen removal effect is achieved; and sludge does not need to be returned, and nitrification sludge and denitrification sludge are independently operated and have no mutual influence on each other, such that the apparatus is simple, and the operation is simple and convenient.
