The invention relates to the technical field of
hexazinone wastewater treatment, in particular to a
hexazinone wastewater desalting process which comprises the following specific steps:
hexazinone wastewater is introduced into a pretreatment mechanism, the pretreatment mechanism comprises a
precipitation barrel and a stirring
barrel, a motor is arranged at the top of the
precipitation barrel, a plurality of stirring rods are arranged on the
peripheral wall of the stirring barrel, and the stirring rods are arranged on the top of the
precipitation barrel; a coagulant is added into the precipitation cylinder, and the output end of the motor drives the stirring cylinder to rotate; sediments in the wastewater are filtered and then introduced into a heating
pipe, and the heating
pipe is connected with a
vacuum pump and a condensation
pipe; the heating pipe is heated, the pressure in the heating pipe is reduced through the
vacuum pump, and
water vapor is guided into the condensation pipe to be condensed and recycled after being evaporated; introducing the residual salt-containing concentrated solution in the heating pipe into a separation mechanism, wherein the separation mechanism comprises a separation box and a semi-permeable membrane; a pressure pump is arranged on the separation box, so that the pressure in the separation box is increased, salt and other soluble
solid substances are intercepted on one side of the semi-permeable membrane, only water molecules are allowed to pass through, and deep
desalination of the wastewater is realized.
