Description

Technical Field

[0002] High-salinity wastewater refers to wastewater from domestic sewage and industrial wastewater with a total salt content greater than 1%. , , It also contains inorganic ions such as glycerol, medium and low carbon chain organic matter, and even radioactive substances. Since the high-salt wastewater has complex and diverse components and high salt content, it has a strong inhibitory effect on the growth of microorganisms. Therefore, the wastewater treatment technology is much more difficult than ordinary sewage treatment. In the existing technology, high-salt wastewater is usually treated using a high-multiple concentration system.

[0003] Chinese patent application No. 2023112495663 discloses a system and method for low-pressure high-concentration of saline wastewater, including a pressure storage tank, a high-pressure pump, a circulation pump, a back pressure valve, a first ball valve, a second ball valve, a flow switch, an electrodeionization device, a high-concentration membrane system, a third ball valve and a drainage pump, wherein the third ball valve and the drainage pump are connected to the pressure storage tank, and the high-pressure pump is connected to the pressure storage tank, the circulation pump is connected to the high-pressure pump, the back pressure valve is connected to the circulation pump, and the first ball valve and the second ball valve are connected to the circulation pump. By setting the pressure storage tank, the high-pressure pump, the circulation pump, the back pressure valve, the first ball valve, the second ball valve, the flow switch, the electrodeionization device, the high-concentration membrane system, the third ball valve, the drainage pump, the impeller, the first helical gear and the second helical gear and other structures, the working pressure can be effectively reduced to achieve low-pressure high-concentration.

[0004] The above-mentioned high-concentration system concentrates the saline wastewater through a high-concentration membrane system. However, the concentration efficiency of the high-concentration membrane is poor and the processing time is long, which reduces the concentration efficiency of the saline wastewater. Therefore, we propose a low-energy consumption high-concentration system and method for saline wastewater. Summary of the invention
