Spiral-wound membrane aeration membrane biological reaction experimental device

The invention belongs to the technical field of biological treatment of sewage and wastewater, and discloses a spiral-wound membrane aeration membrane biological reaction experimental device, which comprises a detachable membrane assembly and a reactor tank body, and the detachable membrane assembly is composed of a device top cover body and a spiral-wound spindle-shaped membrane assembly. 20 hollow fiber membranes (PVDF) are bent into a fusiform shape to form a fusiform shape, the fusiform shape is inserted into an acrylic plate and sealed by epoxy resin electronic filling sealant, a magnetic stirrer enables water to flow, and fluid shear force acts on a biological membrane through contact with the roll type fusiform membrane assembly, so that the biological membrane is more compact. Compared with an existing strip-shaped membrane assembly, the strip-shaped membrane assembly is higher in biological membrane loading efficiency, higher in water quality treatment efficiency and suitable for industrial populariz
