Description

Technical Field

[0001] This utility model relates to a reverse osmosis test device for nuclear power industry wastewater, belonging to the field of wastewater treatment technology. Background Technology

[0002] Nuclear power plants are energy facilities that use nuclear energy to generate electricity, but they produce a certain amount of wastewater during operation. This wastewater may contain radioactive materials, and if it is discharged directly into the environment without treatment, it will cause harm to humans and the environment. Therefore, the treatment of nuclear power plant wastewater is very important.

[0003] Reverse osmosis membrane technology offers significant advantages over traditional processes in nuclear wastewater treatment, including stable effluent quality, relatively low energy consumption, and high concentration ratios. An increasing number of combined processes are based on membrane technology, and with the further maturation of radiation-resistant membrane preparation, the application of membrane technology in nuclear wastewater treatment will become increasingly widespread.

[0004] However, different types of reverse osmosis membranes are suitable for wastewater treatment under different operating conditions. In existing technologies, testing is required during the design phase of the wastewater treatment system. Existing reverse osmosis testing devices have a simple structure, requiring different testing devices to be designed based on different site conditions and wastewater characteristics, which increases testing costs and reduces testing efficiency. Therefore, we propose a reverse osmosis testing device for nuclear power industry wastewater to solve the above problems. Summary of the Invention

The clear water outlet of the reverse osmosis membrane is connected to a pipe, and the high-concentration water output end of the reverse osmosis membrane flows back to the input end of the reverse osmosis membrane through a pipe. Multiple reverse osmosis membranes can be set and connected in parallel. An air vent valve is installed on the return pipe.

[0012] The aforementioned nuclear power industry wastewater reverse osmosis test device has multiple perforations arranged uniformly in a straight line along the corresponding crossbeam, which can be adapted to U-shaped fasteners of different widths, thereby fixing reverse osmosis membranes of different diameters.

[0013] The aforementioned nuclear power industry wastewater reverse osmosis test device uses a high-pressure liquid quick connector for easy assembly and disassembly, and valves are installed on the pipes on both sides of the connection device.
