Abstract

The invention relates to a novel membrane coupled anaerobic bioreactor, comprising an baffle plate anaerobic reactor and a tubular membrane ultrafiltration device; a water outlet of the baffle plate anaerobic reactor is communicated with a water inlet of the tubular membrane ultrafiltration device by pipelines, and a water return port of the tubular membrane ultrafiltration device is communicatedwith a water inlet of the baffle plate anaerobic reactor by pipelines; when treating wastewater, the wastewater flows in from the water inlet of the baffle plate anaerobic reactor and the water inletof the tubular membrane ultrafiltration device, then the wastewater after being treated flows out from a discharge port of the tubular membrane ultrafiltration device, and anaerobic activated sludge which is generated when the tubular membrane ultrafiltration device treats the wastewater reflows to the water inlet of the baffle plate anaerobic reactor. The reactor and the method can separate and fix microorganisms completely, ensure the microorganism concentration in a reaction chamber to be much more than the concentration in a normal anaerobic device, improve the anaerobic treating effect, quicken the anaerobic reaction speed greatly, shorten the residence time of the wastewater effectively and prolong the residence time of the sludge greatly.

Description

technical field [0001] The invention relates to waste water treatment, in particular to a novel membrane biological anaerobic reactor and a method for treating waste water. Background technique [0002] In the microbial treatment device for wastewater treatment, how to effectively trap microorganisms to increase the sludge residence time of the reactor is the main problem that all wastewater treatment processes must face. Every major technical innovation of the anaerobic digestion process involves the core issue of how to effectively retain microorganisms: the previous anaerobic filter (AF) used fillers to fix microorganisms, and later the upflow anaerobic sludge bed (UASB) through three The use of phase separators to separate immobilized microorganisms became the mainstream process at that time. However, the existing microbial treatment devices do not completely and effectively separate and fix microorganisms, and a large number of microorganisms are lost during operation....
