Abstract

The invention discloses a high-packing-density hollow fiber membrane component which comprises a membrane component body, wherein the membrane component body comprises a water collection plastic part, hollow fiber membrane filaments, a large sealing ring and a small sealing ring; the water collection plastic part comprises a water collection joint, a plastic shell, an intermediate bar, a supporting bolt and a membrane component mounting hole; the water collection joint adopts double-step design; two sealing ring slots are arranged on each step for respectively mounting the large sealing ring and the small sealing ring; and the hollow fiber membrane filaments are uniformly arranged at equal distances. The antifouling resistance of the membrane component is improved, a self-supporting structure of the membrane component is saved, and the sealing property is more reliably ensured. The invention also provides a membrane unit which is a membrane unit formed by assembling the membrane component in batches. Thus modular assembly of the membrane unit is realized. According to the design specification requirement, the number of assembled modules is self-defined, and the membrane unit is flexible and diversified in design.

Description

technical field [0001] The invention relates to membrane separation water treatment equipment, and belongs to the technical field of water treatment, in particular to a high packing density hollow fiber membrane module and a membrane unit. Background technique [0002] With the development of membrane technology, the application of membrane bioreactor MBR in wastewater treatment has attracted much attention. Hollow fiber ultrafiltration membrane modules are widely used in MBR wastewater treatment systems due to their high packing density, good filtration effect, long service life and low maintenance cost. [0003] At present, various styles of hollow fiber membrane modules have been formed on the market, in which the hollow fiber membranes are mostly arranged in bundles or sheets, and the inner membrane filaments of a single bundle or single sheet are arranged randomly, so the gap between the membrane filaments is uneven, and it is impossible to achieve membrane stability. ...
