Reverse Osmosis System Applied to Industrial Concentrated Salt Sewage

Abstract

The invention discloses a reverse osmosis system applied to industrial concentrated salt sewage, which comprises a tank body, and two horizontal partitions are arranged opposite to the tank body, and the two horizontal partitions divide the tank body into a raw water chamber, a primary reverse osmosis chamber and In the secondary reverse osmosis chamber, the raw water chamber, the primary reverse osmosis chamber and the secondary reverse osmosis chamber are connected by pipes, and at least one reverse osmosis device is arranged in the primary reverse osmosis chamber. Compared with the prior art, the present invention works simultaneously through a plurality of reverse osmosis devices, improves production efficiency, reduces intermediate pools and booster equipment, and realizes cost reduction and energy consumption reduction; the reverse osmosis devices are driven by ultrasonic vibration devices and aeration devices The liquid in the liquid storage area cleans the reverse osmosis membrane, prevents the clogging of the reverse osmosis device, improves the water purification rate, and reduces the energy consumption required for operation; the reverse osmosis membrane can effectively prevent the charged ions from passing through and let the neutral water molecules free Through the process, the flux of the composite membrane is greatly improved and the service life is long when the salt interception rate remains basically unchanged.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a reverse osmosis system applied to 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 pu...
