Abstract

The invention relates to a tubular membrane bioreactor, comprising a membrane frame, the interior of the membrane frame is provided with a plurality of tubular membrane modules arranged in order, the tops of the membrane modules are gathered through an outlet pipe and then are connected with a suction draining system, the bottom of the membrane frame is provided with an aeration system, the membrane module comprises a plurality of uniformly arranged membrane tubes, and a plurality of flexible friction balls are arranged in a cavity formed by adjacent two membrane tubes. According to the invention, the tubular membrane bioreactor adopts the tubular membrane as the filter membrane, thus fracture and damage of the filter membrane causing water quality deterioration can be avoided; by adding the flexible friction balls in the cavity formed by the membrane tubes, the effective concentration of sludge can be raised, the biochemical treatment efficiency is raised, the water quality of the effluent is raised, and the cost is reduced; the flexible friction balls washout the membrane surfaces, thus the pollution circle of the membrane tubes is prolonged; the distance between the adjacent filter membranes is large and fixed, thus sludge deposit is little; and the filter modules has a simple structure, and the preparation technology is simple.

Description

technical field [0001] The invention relates to a tubular membrane bioreactor. Background technique [0002] Membrane bioreactor is a new type of sewage treatment process. It adds a filter membrane at the end of wastewater biochemical treatment. The biochemically treated water is discharged after passing through the filter membrane. The filter membrane will trap activated sludge and macromolecular substances in the biochemical pool. . MBR membrane technology independently controls the hydraulic retention time and sludge retention time of biochemical treatment, which increases the flexibility of the treatment process, and can design appropriate hydraulic retention time and sludge retention time for different wastewater, while the filter membrane has super strength The mud-water separation function makes the sludge concentration in the biochemical tank greatly increased without worrying about the mud-water separation. [0003] In addition, the operation control of MBR techno...
