Incineration disposal method for high-salinity wastewater

The invention discloses an incineration disposal method for high-salinity wastewater. The high-salinity wastewater is sprayed into a combustion chamber I after being atomized by utilizing a waste liquid spray gun through compressed air. In the combustion chamber I, the consumption of auxiliary fuel and air supply volume are controlled through temperature feedback to keep furnace temperature at 600-700 DEG C. Smoke generated in the combustion chamber I enters a combustion chamber II under the action of an induced draft fan; in the combustion chamber II, the consumption of the auxiliary fuel and the air supply volume are controlled through the temperature feedback to keep the furnace temperature at 1100-1200 DEG C, and moreover, the standing time of the smoke is longer than 2 seconds. Smoke coming out from the combustion chamber II enters a waste heat boiler, and the heat of the smoke is recycled through heat exchange. Smoke coming out from the waste heat boiler is respectively dedusted and deacidified through a bag type dust collector and a smoke deacidification unit, and then, is discharged on the standard. According to the incineration disposal method for the high-salinity wastewater, not only can saline matter in the high-salinity wastewater be separated out through the evaporation of water without coking but also hazardous organic matters in the smoke can be fully destroyed by fire.
