Abstract

The invention relates to a membrane module A which can be used for dialysis, electrolysis operation and enrichment of specific cations in water, and provides the membrane module A which is easy to operate, convenient to maintain and low in energy consumption, has certain specific cation enrichment capability and allows water to seep into. The membrane module A comprises a cation exchange membrane, an ultrafiltration membrane or micro-filtration membrane and a supporting plate with a diversion trench and a hole, and is characterized in that the cation exchange membrane and the ultrafiltration membrane or the micro-filtration membrane are respectively fixed on two sides of the supporting plate.

Description

technical field [0001] The invention provides a complete membrane module A, which can be used for dialysis, electrolysis operation and specific anion enrichment in water. Background technique [0002] Ion exchange membrane has strong ion selective permeability, high separation efficiency, low energy consumption, and less pollution, so it has important application value in many fields. [0003] In recent years, ion exchange membranes have been widely used in water supply and sewage treatment industries to separate target components and enrich them for subsequent treatment. Seung Joo Lim et al. used a single ion exchange membrane to achieve NH in wastewater 4 + However, due to the use of a single membrane and solutions on both sides of the membrane, large-scale sewage treatment applications cannot be realized, and when the membrane is fouled, it is difficult to clean the membrane; Yasuyuki FUKUMOTO and others use tubular ion-exchange membranes to achieve NO in wastewater 3 ...
