Multilayer fiber bundle biofilm purification device

Abstract

Belonging to the technical field of biofilms, the invention discloses a multilayer fiber bundle biofilm purification device. The multilayer fiber bundle biofilm purification device comprises a purifier installed on a base, the bottom end of the purifier is fixedly connected to a hollow tapered flow guide body, fiber bundle biofilms are positioned and bound in the vertical direction through aeration pipes, thus effectively avoiding position deviation and mutual winding easily caused by aeration disturbance or water flow impact, meanwhile, a movable filter plate in contact with sewage is also sleeved to the aeration pipes, after the movable filter plate is pressed downwards, the densities of the filter layers of the fiber bundle biofilms increase gradually along the water flow direction, andthe pores of the corresponding filter layers are gradually reduced, thus realizing deep filtration, and after the filtration work is completed, the movable filter plate is reset upwards under the action of a traction reset mechanism, so that the fiber bundle biofilms can be reset upwards to be in a relaxed state again, and aeration treatment performed at the moment facilitates uniform diffusion of oxygen into the fiber bundle biofilms.

Description

technical field [0001] The invention relates to the technical field of biofilms, in particular to a multi-layer fiber bundle biofilm purification device. Background technique [0002] In the field of sewage treatment, the membrane bioreactor, which has been developed rapidly in recent years, occupies a very important position. Among them, the fiber filter membrane is a kind of water treatment filter device. The fiber filter membrane is mainly composed of several fiber bundles. Effective filtration is achieved by forming a filter layer. [0003] The fiber bundles in the fiber filter membrane in the prior art are made by winding fibers or binding, and each fiber bundle is composed of at least two sections of fiber bundles, and the sewage flows through the fiber bundles for filtration or directly passes through the fibers. The bundle is put into the sewage to absorb the sundries. Since the fibers are prone to position shifting and mutual entanglement under aeration disturbanc...

AI Technical Summary

Problems solved by technology

Since the fibers are prone to position shifting and mutual entanglement under aeration disturbance and water flow, the hollow fiber floats a lot during use, and after being entangled, sludge and fibrous substances are easily accumulated in the winding place. Since there is no A certain positioning of the fiber bundle will have a certain impact on the subsequent purification
