Embodiment Construction

[0033] A submerged ultrafiltration method, comprising the following steps:

[0034] The submerged ultrafiltration membrane is installed in the ultrafiltration water pool, and the suction pump arranged outside the ultrafiltration water pool forms a negative pressure, so that the water outside the submerged ultrafiltration membrane enters the submerged ultrafiltration membrane In the membrane cavity, ultrafiltration membrane treatment is carried out. The suction pressure of the suction pump is 5-12kpa.

[0035] A submerged ultrafiltration device, comprising:

[0036] Ultrafiltration pool 5;

[0037] The submerged ultrafiltration membrane 6 is installed in the ultrafiltration pool 5;

[0038] The suction pump 7 is arranged outside the ultrafiltration pool 5, and is connected with the membrane tube water outlet of the submerged ultrafiltration membrane 6 through a pipeline.

[0039] see figure 1 . A pure water preparation system includes: a pretreatment system, an ultrafiltr...

Abstract

The invention relates to an ultrafiltration method, in particular to an immersed ultrafiltration method, and further relates to a device for implementing the method and a preparation system of pure water adopting the device. The immersed ultrafiltration method comprises the following steps of: arranging an immersed ultrafiltration film in an ultrafiltration pond; sucking with a sucking pump arranged outside the ultrafiltration pond to form a negative pressure; and making water outside the immersed ultrafiltration film enter a film cavity of the immersed ultrafiltration film for performing ultrafiltration treatment. The immersed ultrafiltration device comprises the ultrafiltration pond, the immersed ultrafiltration film and the sucking pump. The preparation system of pure water comprises the immersed ultrafiltration device. According to the invention, the problem that the film is difficult to clean in the conventional process for preparing pure water with a pressure type ultrafiltration film is mainly solved.

Description

technical field [0001] The invention relates to an ultrafiltration method, in particular to a submerged ultrafiltration method, and also relates to a device for realizing the method and a pure water preparation system using the device. Background technique [0002] In the production process of iron and steel enterprises, a large amount of pure water needs to be used for equipment cooling, boiler steam supply water and cold-rolled slab cleaning, product cooling, etc. The quality of pure water is closely related to the safe operation of equipment and product quality. At present, in water treatment technology, the preparation processes and methods of pure water mainly include ion resin exchange method, distillation method, electrosorption method, membrane treatment method and electrodialysis, etc. The treatment process has its own characteristics. The ion resin exchange method is a traditional pure water preparation process. The system operation is relatively stable. The water ...
