Abstract

The invention discloses a biological stuffing fixed type HMBR process aeration tank. A plurality of guide walls are arranged in an aeration tank; membrane modules are arranged between the guide wallsand tank walls; an external self-priming pump is connected with the membrane modules; an aeration head is arranged under the membrane modules; a sludge discharging pipe is arranged on the bottom of the aeration tank; the fixed biological stuffing is arranged in the aeration tank; raw water is pumped into the aeration tank by a raw water pump through a grating. The invention has the beneficial effects that the aeration tank has high capacity of removing nitrogen and phosphorus and excellent dredging effect.

Description

technical field [0001] The invention belongs to the technical field of biological filler aeration tanks, and relates to a biological filler fixed HMBR process aeration tank. Background technique [0002] Install biological filler in the aeration tank of a common membrane bioreactor (CMBR), and after a certain period of operation, a certain thickness of biofilm will grow on the filler. This form of membrane bioreactor is called a composite membrane bioreactor. (HMBR). Compared with CMBR, there are not only suspended microorganisms (activated sludge) but also adherent microorganisms (biofilm) in the aeration tank of HMBR. The test results show that compared with CMBR, HMBR has better biodegradability due to the obvious increase of biomass. In addition, compared with CMBR, HMBR also has a good ability to control membrane fouling, and the operating cycle of the membrane module is greatly extended. The biological filler used is a mobile biological filler, and the filler is in ...
