Abstract

The invention discloses a membrane module realizing the on-line monitoring and control of membrane pollution by using the ultrasonic technology, belonging to the technical field of water treatment. The membrane module comprises a water inlet plate, a membrane wall, a spiral membrane, a water outlet plate, an ultrasonic transducer, a permeate outlet, a condensed water outlet, and an intelligence control system. The membrane module disclosed herein can monitor the membrane pollution in real time, utilizes the effects of ultrasound to destroy the concentration polarization according to a set switch-on strategy, and disturbs and alleviates the formation of membrane pollution, and the cavitation can enhance the effect of membrane cleaning. According to the invention, by using a special mode of using ultrasound, the damage of ultrasound for the membrane material is greatly reduced, the application range of ultrasound is enlarged, the service time of the membrane module is prolonged. The membrane module is suitable for ultrafiltration, nanofiltration, reverse osmosis and the like.

Description

Technical field [0001] The invention belongs to the technical field of water treatment, and specifically relates to an online ultrasonic monitoring and cleaning integrated membrane module. Background technique [0002] Because of its energy-saving, high-efficiency, simple and easy-to-operate characteristics, membrane separation technology has received widespread attention. This technology is widely used in various fields such as food, medicine, chemical industry, and environmental protection. Although new membrane materials and membrane modules are constantly being developed, in practical applications, the membrane flux will gradually decrease with time. Membrane fouling and concentration polarization are the main reasons for the decrease in membrane flux. . The traditional method is to add chemical reagents to chemically clean the membrane tube after a period of use. Although chemical cleaning can increase the membrane flux to a certain extent, it also brings secondary polluti...
