Description

Technical Field

[0001] The utility model belongs to the field of MBR technology, in particular to a mini MBR technology testing machine. Background Art

[0002] The membrane bioreactor (MBR) is a novel wastewater treatment system that organically combines membrane separation technology with biological treatment technology. Membrane modules replace the secondary settling tank at the end of traditional biological treatment technology. This maintains a high activated sludge concentration within the bioreactor, increasing the organic load of biological treatment, thereby reducing the wastewater treatment facility footprint and reducing excess sludge by keeping the sludge load low. Membrane separation technology primarily captures activated sludge and macromolecular organic matter in the water. Also known as an MBR reactor, an MBR typically includes an inlet well, a grid, a regulating tank, and a reaction tank. Due to its large footprint, it is not suitable for university teaching demonstrations or biological strain culture experiments. Utility Model Content
