Abstract

The invention relates to a baffled combined membrane bioreactor. The baffled combined membrane bioreactor is characterized in that the operation of the complete bioreactor is controlled by an automatic control system, and the bioreactor comprises a baffled reaction zone (1), buffer zones and membrane reaction zones, through which wastewater passes from inlet to outlet; the baffled reaction zone (1) is communicated with a first buffer zone (2-1) and a second buffer zone (2-2) respectively in an output manner, the first buffer zone (2-1) is communicated with a first membrane reaction zone (3-1), and the second buffer zone (2-2) is communicated with a second membrane reaction zone (3-2). The baffled combined membrane bioreactor has the advantages that the treatment efficiency is high, the quality of outlet water is high and stable, the bioreactor is compact and is small in floor area, the trapping, growth and reproduction of slow-proliferation nitrifying bacteria are facilitated, the fully-automatic control can be realized through a PLC (Programmable Logic Controller), and the operation management is simple.

Description

[0001] technical field [0002] The invention relates to a baffled combined membrane bioreactor, belonging to the technical field of membrane-bioreactor structures. Background technique [0003] At present, the MBR membrane bioreactor is a new type of water treatment technology that combines a membrane separation unit and a biological treatment unit. The membrane module replaces the secondary settling tank to maintain a high active sludge concentration in the bioreactor and reduce the occupation of sewage treatment facilities. land and reduce sludge volumes by keeping sludge loads low. [0004] Technical defects of existing MBR membrane bioreactor: [0005] 1. In the existing MBR membrane bioreactor, an anoxic pool is set up when denitrification is required. The anoxic pool is usually set up separately, and the nitrifying liquid is returned to the anoxic pool by setting a sludge return pump in the MBR membrane bioreactor. Oxygen tank, agitated by anoxic tank mixer to conv...
