Abstract

The invention discloses a facultative anaerobic membrane bioreactor wastewater treatment device which comprises a device body provided with a water inlet and a water producing port, wherein an intensified anaerobic reaction zone and a composite facultative anaerobic fluidized bed MBR reaction zone are sequentially formed in the device body from the water inlet to the water producing port; the intensified anaerobic reaction zone consists of at least two reaction chambers connected in series; biological stuffing is filled in the reaction chambers; an aeration device is arranged at the bottom of the composite facultative anaerobic fluidized bed MBR reaction zone; the composite facultative anaerobic fluidized bed MBR reaction zone comprises a fluidized bed reaction zone and an MBR reaction zone; fluidized bed stuffing is suspended in the fluidized bed reaction zone; an immersed ultrafiltration membrane component is arranged in the MBR reaction zone; a water production pipeline of the immersed ultrafiltration membrane component is connected with a water production port. The invention also provides a wastewater treatment process for performing wastewater treatment by adopting the wastewater treatment device. The wastewater treatment device and the wastewater treatment process have the advantages of good wastewater treatment effect, stable water production and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a facultative membrane biological reaction sewage treatment device and a treatment process. Background technique [0002] In the prior art, there are many kinds of sewage treatment processes, each of which has certain advantages. However, due to the complex composition of pollutants in sewage, it is generally difficult to make the water quality discharge up to standard by using a single sewage treatment process. Such as anaerobic hydrolysis acidification pretreatment technology, anaerobic hydrolysis acidification pretreatment technology is a biological technology to effectively remove pollutants, mainly under the action of hydrolytic bacteria and acid-producing bacteria, the insoluble organic matter is hydrolyzed into soluble organic matter, and difficult Biodegradable macromolecules are converted into easily biodegradable small molecules. However, anaerobic hydrolytic acidif...
