Splicing curtain type self-filtering filter membrane assembly

Abstract

The invention discloses a splicing curtain type self-filtering filter membrane assembly, belonging to the field of water treatment equipment. The splicing curtain type self-filtering filter membrane assembly comprises a frame, air supply pipes, an aerator, an MBR module, a water collecting pipe, quick connecting pipes and a bottom water collecting pipe, wherein the air supply pipes are mounted attwo ends of the bottom surface of the frame and connected with two ends of the aerator through the quick connecting pipes; the upper ends and the lower ends, close to the MBR module, of the water collecting pipe and the bottom water collecting pipe are respectively clamped with the upper end and the lower end of the MBR module through the quick connecting pipes; and a plurality of quick connectorsare respectively arranged on the surfaces of the air supply pipes, the aerator, the MBR module and the water collecting pipe. By adopting the microporous aerator with a micro-arch plate type structure, the load impact resistance and the structural stability of the microporous aerator are enhanced, an effective aeration area is maximized, bubble coalescence is reduced, an oxygen utilization rate is improved, resistance loss is reduced, and meanwhile, microorganism enrichment can be effectively prevented, so aeration holes are prevented from being blocked by sludge, the service life of the aerator prolonged, and the stability of an aeration system is enhanced.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, and more specifically, the invention is an adhesive curtain-type self-filtering membrane module. Background technique [0002] MBR membrane module is the core component of membrane-bioreactor technology application. The performance of MBR membrane module directly affects the investment, operation cost and service life of MBR. MBR series immersed curtain membrane module is specially designed for membrane-bioreactor The developed MBR membrane module has the following characteristics: the material of the MBR membrane module is polypropylene, the membrane module has good mechanical strength, it is very suitable for sewage treatment, and it is not easy to break under high-intensity air scrubbing; the chemical performance is stable and oxidation-resistant Strong acid and strong alkali cleaning; in actual use, the membrane filaments are parallel to the water surface, and the aeration s...

Problems solved by technology

[0003] However, there are still some shortcomings in its actual use. For example, the water treatment equipment with adhesive curtain self-filtering membranes currently on the market has the disadvantages of inconvenient installation and low aeration efficiency due to its huge size, and due to the use of bottom aeration The setting of the trachea, the oxygen utilization efficiency in aeration is extremely low, and the uneven aeration results in low oxygen utilization efficiency and high energy consumption, resulting in the shortcoming that it cannot be used for a long time and is extremely inconvenient to maintain
