Abstract

A submerged membrane bioreactor with non-fabric filter is composed of a tank containing microbial mixture liquid and a fitler module submerged in the said mixture liquid. The filter module has a penetrable surface for passing the mixture liquid through it, and is composed of a porous supporting material with the said penetrable surface and a second surface, and a non-fabric membrane with a thickness between 0.1-2 mm and pores between 0.2-100 microns covering on the second surface.

Description

technical field

[0001] The present invention relates to a submerged membrane bioreactor (submerged membrane bioreactor), in particular to a non-fabric membrane filter module configured therein. Background technique

[0002] When using the activated sludge process to treat wastewater, the idea of ​​solid-liquid separation membrane biological treatment technology using ultrafiltration (MF) or microfiltration (MF) units to replace sedimentation tanks and sand filter tanks began in 1969. Compared with the traditional activated sludge method, solid-liquid separation membrane biological treatment technology has many technical advantages, such as long sludge residence time, treatment of wastewater with high concentration changes, no need for sedimentation unit (saving space), etc. So far, there are at least 500 solid-liquid separation membrane biological treatment plants in operation around the world, and most of the membrane materials used are microporous (pore...
