▎ 摘　　要

NOVELTY - The system has a regulating tank (100) for storing sewage to be treated. The membrane concentration tank (200) is provided with a first immersed ceramic membrane module and a first aeration pipe (210). The first submerged ceramic membrane module (400) has a first filtrate outlet (410) for the suction pump to draw filtrate. The water outlet of the membrane concentration tank is connected with the water inlet of the anaerobic membrane biological reaction tank (300). The anaerobic membrane biological reaction tank is provided with a second submerged ceramic membrane module (500) and a second aeration pipe located below the second submerged ceramic membrane module. The exhaust port of the anaerobic membrane bioreactor is in communication with the first exhaust pipe and the second exhaust pipe. The first exhaust pipe (001) is in communication with the first aeration pipe. The second exhaust pipe (002) is in communication with the second aeration pipe. USE - Sewage anaerobic membrane biological treatment system used for low water inlet concentration of municipal sewage treatment plant. ADVANTAGE - The system solves the technical problem caused by low water inlet concentration of municipal sewage treatment plant, provides a set of efficient and feasible technology solving system and method, and greatly shortens the traditional sewage and sludge treatment process flow under the premise of ensuring the treatment effect, reducing floor space, saving energy and reducing consumption. The inorganic ceramic film is used for replacing the traditional organic film. The material flux is large. The acid and alkali resistant is better. The mechanical strength is strong. The durability is good. The system has the unreplaceable advantage in the process of concentrating, filtering, and gas cleaning. The municipal sewage can be discharged up to the standard after the membrane effluent of this system is denitrified and dephosphorized, and the higher biomass yield can be obtained. The generated biomass biogas can be partially returned to the first aeration pipe in the membrane concentration tank and the second aeration pipe in the anaerobic membrane biological reaction tank. The system can improve treatment effects, and reduce treatment costs. The biogas slurry produced has the potential to recover phosphorus or be used as biological fertilizer. The sewage sludge treatment process has low carbon and environmental protection and is capable of realizing resource and energy recovery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a sewage anaerobic membrane biological treatment method.
