Seawater reverse osmosis device and method

Abstract

The invention discloses a seawater reverse osmosis device and method, the reverse osmosis device comprises a pretreatment mechanism comprising an air flotation, a filter pool and a raw water pool connected in sequence; a reverse osmosis mechanism; and a concentrated water treatment mechanism comprising a concentrated water pool and a three-dimensional electrode reactor; wherein the water inlet endof the reverse osmosis mechanism is connected with the raw water pool, the concentrated water pool is connected with a concentrated water outlet end of the reverse osmosis mechanism, and the water outlet end of the three-dimensional electrode reactor is connected to the air flotation. The seawater reverse osmosis method comprises electrolyzing concentrated water after seawater reverse osmosis andadding the concentrated water to to-be-reversely-osmosed seawater. The concentrated salt water after the seawater reverse osmosis is electrolyzed sequentially by the three-dimensional electrode reactor and an electrolytic cell, hypochlorite having a strong oxidizing property is formed, and the concentrated salt water with the hypochlorite is added to the air flotation, the reverse osmosis devicefacilitates to filter impurities in the seawater by the air flotation and the filter pool while oxidizing of the seawater, and can avoid the fishy odor of fresh water formed by the subsequent reverseosmosis.

Description

technical field [0001] The invention relates to seawater reverse osmosis technology, in particular to a seawater reverse osmosis device and method. Background technique [0002] At present, with the increasingly serious problem of water shortage, reverse osmosis devices that can convert seawater into fresh water have been widely used. Then, with the continuous deterioration of the marine environment, abnormal phenomena often occur in the marine ecosystem, such as red tides, which put forward new requirements for reverse osmosis devices that use seawater as a water source, that is, more in-depth pretreatment of seawater is required. Especially for the treatment of marine algae, otherwise, the fresh water formed after the reverse osmosis of the reverse osmosis device has a fishy smell, which is not conducive to the experience of using the reverse osmosis fresh water. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned t...
