Abstract

The invention provides active denitrification nitrogen removal membrane bioreactor sewage treatment equipment. A tank is internally provided with an aerobic zone and a membrane zone, a sewage inlet isformed in the aerobic zone, the membrane zone is internally provided with a membrane bioreactor membrane and a nitration liquid return pipe, an inlet of the nitration liquid return pipe is formed inthe upper part of a sewage zone at the bottom of the tank, an electric brake valve is arranged at the position of the inlet, the nitration liquid return pipe is connected with a water flow power draught fan, and an outlet of the nitration liquid return pipe passes through the tank. The invention also provides an active denitrification nitrogen removal membrane bioreactor sewage treatment system. An sewage inlet of the aerobic zone is connected to a sewage outlet of an adjusting tank, a sewage inlet of the adjusting tank is connected to a grating pool, the outlet of the nitration liquid returnpipe passes through the tank and is connected with the adjusting tank, and a sewage outlet at the bottom of the tank is connected to a sludge drying pool. According to the equipment provided by the invention, the denitrification capacity of sewage treatment is improved greatly, and the equipment has an active denitrification function, is high in denitrification efficiency and does not depend on the height of water level.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to an active denitrification and denitrification MBR (membrane bioreactor) sewage treatment equipment and system. Background technique [0002] figure 1 with figure 2 It is a structural schematic diagram of the existing sewage treatment system. The existing sewage treatment system is composed of grid pool 1, regulating pool 2, MBR (membrane bioreactor) integrated sewage treatment equipment 3, sludge drying pool 4 and other components . [0003] Wherein, the gate pool 1 is provided with a sewage inlet and a sewage outlet, and the sewage outlet is connected to the sewage inlet of the regulating tank 2 . Grille 11 and spacer 12 are housed in grid pond 1, are used for intercepting large debris. [0004] The regulating tank 2 is equipped with a submersible mixer 21 and a lift pump 22, and the lift pump 22 is connected to the sewage inlet of the MBR integrated sewage treatment equipment ...
