Novel water treatment membrane assembly

Abstract

The invention discloses a novel water treatment membrane assembly, which includes: a plurality of water transporting pipes which are communicated with each other to form a water transporting pipeline in a framework structure; a plurality of water treatment membrane piles which are communicated with the water transporting pipeline and are installed on the framework structure; and a plurality of aeration pipes, of which the number is equal to that of the water treatment membrane piles, wherein the aeration pipes are arranged correspondingly to the water treatment membrane piles respectively. Each water treatment membrane pile includes a plurality of membrane sheets, a sealing ring, a fixing ring and a water collecting pipe. A mounting hole is formed in the middle of each membrane sheet, wherein the size of the mounting hole is matched with the outer diameter of the water collecting pipe. The sealing ring is matched with the mounting hole. Two ends of the water collecting pipe are communicated with the water transporting pipes at corresponding positions. Each water collecting pipe is provided with a plurality of water outlet holes. In the membrane assembly, disk-type membrane sheets are employed, wherein all of the membrane sheets are connected together in series to form a cylindrical structure to form a structure with peripheric liquid inlet and central water outlet. On the basis of ensuring sufficient membrane contact area, occupied volume of the membrane piles is greatly reduced, so that a more membrane area in the membrane assembly is achieved with the same volume, thereby improving water treatment performance.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a novel water treatment membrane module. Background technique [0002] Membrane technology, known as the water treatment technology of the 21st century, has developed rapidly in the past 40 years. Compared with traditional water treatment technology, membrane technology has the advantages of energy saving, less investment, easy operation and high treatment efficiency, and its application has brought huge environmental and economic benefits to human beings. Membrane technology has a wide range of applications in water treatment, both for drinking water treatment and wastewater treatment, and also involved in water treatment in some special industries. [0003] In the application process of membrane technology, membrane fouling is the biggest problem. With the prolongation of the use time, pollutants are adsorbed on the surface of the membrane, and after long-term accumul...

AI Technical Summary

Problems solved by technology

With the prolongation of the use time, pollutants are adsorbed on the surface of the membrane, and after long-term accumulation, the membrane pores will be blocked and the membrane treatment performance will be reduced.
