Threaded treatment device for desalinating high-salinity wastewater based on molybdenum alloy squirrel cage flameproof motor

The invention relates to a high-salinity wastewater treatment device, in particular to a threaded treatment device for desalinating high-salinity wastewater based on a molybdenum alloy squirrel cage flameproof motor. The threaded treatment device for desalinating the high-salinity wastewater based on the molybdenum alloy squirrel cage flameproof motor comprises a clarification tank, a filtration tank, a sodium ion exchanger, a carbon remover, a three-level sleeved fine filter and a threaded energy recovery and reverse osmosis combination member. As an improvement, a pressurization threaded connector, a depressurization threaded connector, a suction port threaded connector and a pressure storage threaded connector are arranged on a pressure exchange threaded booster pump; the pressurization threaded connector comprises a threaded lug boss of a volute outlet, internal threads of the outlet lug boss and external threads at the lower end of a conversion high-pressure valve pipe, wherein the external threads at th
