Abstract

The invention discloses an integrated aerobic granular sludge dynamic membrane bioreaction wastewater treatment device, which comprises a membrane bioreactor (1) loaded with aerobic granular sludge and is characterizes in that the membrane bioreactor is provided with a wastewater inlet (2), a filtering water outlet (3) and a direct water outlet (4), a membrane component (5) is arranged in the membrane bioreactor, a hollow structure is arranged in the membrane component (5), the membrane component (5) is communicated with the filtering water outlet (3) via a filtering pipeline, both of the highest height of the membrane component (5) and the height of a liquid level of the direct water outlet (4) are lower than the height of the liquid level of the filtering water outlet, and a lower end of the membrane component is provided with a micropore aerator (6). The device is economical, high-efficient and stable in wastewater treatment, and the reactor is compact in structure and wide in application range, occupies small area, and is flexible to operate.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an integrated aerobic granular sludge dynamic membrane biological reaction wastewater treatment device. Background technique [0002] Membrane bioreactor (MBR), as an efficient and compact wastewater biological treatment technology, has been rapidly developed and widely used in recent years. However, there are two major problems in practical application of this technology: high cost and membrane fouling. At present, domestic and foreign research on MBR membrane fouling control mainly focuses on two aspects: the optimization of the membrane material itself and the optimization of the activated sludge system. [0003] In terms of membrane material optimization, an important development direction in recent years is to use cheap coarse mesh membrane materials (such as nylon mesh, steel mesh, non-woven fabrics, etc.) to replace traditional microfiltration or ultr...
