Abstract

The invention discloses a reverse osmosis device for processing industrial sewage with a high salt concentration. The reverse osmosis device comprises an upper mounting base, a lower mounting base, and a reverse osmosis film. The upper mounting base, the lower mounting base, and the reverse osmosis film form a liquid storing area. A filter cylinder is vertically arranged in the liquid storing area. The filter cylinder divides the liquid storing area into an external osmosis area and an internal osmosis area. A cleaning assembly is arranged in the external osmosis area. The upper mounting baseis provided with a liquid inlet. The lower mounting base is provided with a concentrated water outlet and a slag outlet. Compared with the prior art, through an ultrasonic vibration device and an aeration device, liquid in the liquid storing area is driven to wash the reverse osmosis film gradually; the obstruction of the reverse osmosis device is prevented; the purified water output is effectively increased; the energy consumption is largely reduced; the reverse osmosis film can effectively block charged ions and makes electrically neutral water molecules pass through freely; the salt rejection rate is basically the same, the throughput of the composite film is greatly increased, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of reverse osmosis, in particular to a reverse osmosis device for treating industrial concentrated salt sewage. Background technique [0002] Chemical, printing and dyeing, medicine, food and many other industrial productions will produce a large amount of high-salt wastewater, and the discharge of such wastewater will cause serious pollution to the environment. Therefore, how to deal with high-salt wastewater has become a hot research topic. Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as the driving force to separate the solvent from the solution. Because it is opposite to the direction of natural infiltration, it is called reverse osmosis. According to the different osmotic pressures of various materials, the reverse osmosis pressure greater than the osmotic pressure can be used, that is, the reverse osmosis method, to achieve the purpo...
