摘要
The present invention discloses a novel membrane aerated anaerobic granular sludge reactor, belonging to the technical field of sewage treatment. The reactor solves the problems of low solubility of gas substances in an aqueous solution, large gas-liquid mass transfer resistance and low mass transfer rate. The top of a reactor body is provided with a water outlet, and the middle side wall of the reactor body is provided with a middle water outlet; the middle water outlet of the reactor body is connected with an water inlet of a membrane module; an water outlet of the membrane module is connected with a bottom water inlet of the reactor body through a circulating pump, a water inlet is connected with the bottom water inlet of the reactor body through a feed pump, a high pressure or pressurized gas cylinder outputs high pressure or pressurized gas to the membrane module, and a gas pressure regulating valve is arranged between the high pressure or pressurized gas cylinder and the membrane module. The novel membrane aerated anaerobic granular sludge reactor improves the content of a gas substrate therein, and shortens the formation time of granular sludge. The efficient nitrogen removal and greenhouse gas emission reduction method has higher nitrate and ammonia removal rates and a higher dissolved methane removal rate within a shorter time.
