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

Abstract

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 the lower end of the conversion high-pressure valve pipe is in close connection with the internal threads of the outlet lug boss, and the internal threads of the outlet lug boss are located in the threaded lug boss of the volute outlet to constitute the pressurization threaded connector; two sides of a threaded separating plate of the booster pump respectively cooperate with a pressure exchange threaded machine housing and a primary pump housing, wherein primary flange external threads are formed on the primary pump housing, and exchanger flange external threads are formed on an upper opening of the pressure exchange threaded machine housing. The threaded treatment device for desalinating the high-salinity wastewater based on the molybdenum alloy squirrel cage flameproof motor disclosed by the invention has a simple structure as a threaded pipeline connection structure is adopted.

Description

technical field [0001] The invention relates to a high-salt wastewater treatment device, which belongs to the technical field of power plant wastewater treatment engineering, and in particular to a desalination thread treatment device for high-salt wastewater of a molybdenum alloy squirrel cage explosion-proof motor. Background technique [0002] At present, the reverse osmosis desalination process has been widely used in seawater desalination, reclaimed water reuse desalination and natural water desalination, etc., because the reverse osmosis treatment process requires the quality of influent water to be pollution index SDI<3, when water When using reverse osmosis to desalinate, a certain pretreatment process is required before reverse osmosis. At present, the typical pretreatment processes are: [0003] (1) clarification filtration + multi-media filtration + activated carbon treatment + reverse osmosis; [0004] (2) clarification filtration + ultrafiltration / microfiltr...
