Abstract

The invention discloses a deionized water all-in-one treatment method and device for water treatment of a micro-polluted water source. The all-in-one treatment method is combined with a forward osmosis technology and a membrane capacitance deionization technology. The forward osmosis technology can effectively remove micro-polluted substances from water, and a membrane capacitance deionization can concentrate and recycle a draw solution, so that removal of pollutants from water can be realized, and the draw solution is recycled; meanwhile, the problems of high membrane pollution rate, high energy consumption and the like are also solved; a forward osmosis unit and a multi-stage membrane capacitance deionization unit are simultaneously arranged in the treatment device; and the treatment device is convenient to mount and easy to operate, realizes effective removal of the pollutants from the water and has the advantages of low energy consumption, low membrane pollution rate, simplicity for operation and the like.

Description

technical field [0001] The invention belongs to the technical field of micro-polluted water source water treatment, and in particular relates to an integrated deionization treatment method and device thereof for micro-polluted water source water treatment. Background technique [0002] At present, with the continuous development and improvement of membrane science, the technology of combining membrane separation technology with other water treatment technologies has attracted more and more attention from researchers. However, some existing membrane separation technologies, such as ultrafiltration membrane, nanofiltration membrane and reverse osmosis membrane, mainly use the hydraulic pressure difference on both sides of the membrane to separate and remove pollutants. These technologies have the disadvantages of high energy consumption and easy membrane fouling. As the separation radius decreases, the filtration resistance of the membrane continues to increase, and the energ...
