The system comprises a flue gas diversion system, an ultrasonic atomization system, a demisting system, a water treatment system, a dosing system and an automatic control system. Flue gas flows through an ultrasonic flue through diversion, in the ultrasonic flue, a circulating desulfurization compound lye is pressurized through a high pressure pump and is atomized by an ultrasonic device to form uniform fog groups composed of micron-sized fine fog drops, the ultrasonic flue is fully filled with the fog groups, the fog groups block passing flue gas, SO2 in the flue gas is captured by an atomization desulfurization agent and fast undergoes a reaction, an ultrasonic generator releases ultrasonic wave and shakes the desulfurization compound lye to obtain atomized gas having sizes of less than 5-10 microns, the atomized gas of the desulfurization compound lye has large surface tension and a certain viscidity and can effectively capture dust in flue gas, an ultrasonic generator can effectively capture ammonia escaping in the denitrification process and the escaped ammonia in the ultrasonic vibration atomization environment and nitrogen oxides further undergo a reduction reaction.

The invention relates to an energy-saving water treatment system and method for gasified concentrated water, and the system comprises an evaporative crystallization unit located at the downstream of a membrane concentration unit, and the evaporative crystallization unit is configured as follows: first-stage concentrated water sequentially enters a falling film module and a forcing module in a downstream manner; the first-stage concentrated water exchanges heat with second-effect and/or third-effect mixed distilled water and live steam condensate, then enters a first-effect falling film circulation evaporator and is evaporated in the first-effect falling film circulation evaporator according to a first saturated steam temperature based on corresponding pressure of gas-phase secondary steam; secondary steam generated by the first-effect falling film circulation evaporator serves as a second-effect heat source to heat the second-effect falling film circulation evaporator. According to the invention, material components are estimated based on the gas phase evaporation temperature of each effect and liquid phase concentration analysis in the evaporation process, and the internal pressure of each evaporator is changed by setting the first saturated steam temperature, the second saturated steam temperature and the third saturated steam temperature, so that the steam heating efficiency is improved, the investment and operation energy consumption of the system are reduced, and the energy consumption is reduced. The system blockage is prevented.

The invention discloses a separation device, a sewage treatment system and a sewage treatment method.
