The invention discloses a
treatment system and evaporating treatment method for high
salinity wastewater. The
treatment system comprises a desulfurization waste water
conventional treatment device, a high-
salinity water concentration device, a concentrated high-
salinity water storage pool and an atomizer which are connected in sequence. The
treatment system further comprises a high-salinity water
boiling point reducing device which is arranged at any appropriate position in front of the concentrated high-salinity
water storage pool. The water spraying amount of concentrated high-salinity water sprayed out of the atomizer can be adjusted. The treatment method comprises the steps that 1, after desulfurization waste water is subjected to
conventional treatment, upper-layer clear water, namely, high-salinity water is collected, the high-salinity water is concentrated to be reduced, and concentrated high-salinity water is formed and stored in the concentrated high-salinity
water storage pool; 2, the concentrated high-salinity water in the concentrated high-salinity water
storage pool is sprayed into a
flue between a
hearth and a dust remover and / or the
hearth through the atomizer and subjected to atomization and
evaporation, and
crystal substances are mixed into
coal ash to be removed together, wherein the
water spray amount of the concentrated high-salinity water sprayed into the
flue between the
hearth and the dust remover and / or the hearth is adjusted according to
flue gas temperature.
