Embodiment

[0026] The filter membrane cleaning method of the present embodiment specifically comprises the following steps:

[0027] a. First obtain the cleaning device with the following structure, the cleaning device is as follows: figure 1 As shown, it includes a cleaning container, the upper end of the cleaning container is open and has a matching container cover to realize sealing, the upper end of the cleaning container is connected with a water inlet pipe 5, and the middle of the cleaning container is horizontally provided with a metal mesh grounding electrode 2, One end of the grounding electrode 2 is connected to the cleaning container through a grounding wire and grounded. The lower part of the cleaning container away from the water inlet pipe is connected to a water outlet pipe. The upper part of the grounding electrode 2 is vertically opposite to the needle electrode 1. The upper end of the needle-shaped electrode 1 is fixed and connected to the high-voltage pulse power suppl...

Abstract

The invention discloses a filtering membrane cleaning method. The filtering membrane cleaning method is characterized in that a to-be-cleaned filtering membrane is placed in a liquid phase and subjected to liquid phase discharge through electrodes of a high-voltage pulsed power supply, so that corona discharge, glow discharge or streamer discharge occurs in the liquid phase; under the physical and chemical effect produced in the discharge process, substances blocking membrane holes are separated from the membrane holes, and the filtering membrane is cleaned. The filtering membrane can be efficiently cleaned, and membrane flux is rapidly recovered to realize membrane regeneration. The filtering membrane cleaning method has the advantages of short cleaning period, low cost and good effect.

Description

technical field [0001] The invention relates to the technical field of membrane separation; in particular, it relates to a filter membrane cleaning method utilizing high-voltage pulse discharge treatment. Background technique [0002] Membrane separation is a new separation technology that appeared in the early 20th century and rose rapidly after the 1960s. Using a filter membrane with selective separation function, the process of using the selective separation of the membrane to achieve the separation, purification and concentration of different components of the feed liquid is called membrane separation. Membrane separation technology has been widely used in food, medicine, biology, Environmental protection, chemical industry, metallurgy, energy, petroleum, water treatment, electronics, bionics and other fields have produced huge economic and social benefits, and have become one of the most important means in today's separation science. [0003] Due to the characteristic...
