Abstract:

To realize thermal power plant waste water zero emission, technology of desulfurization waste water preprocess, desulfurization waste water concentrated treatment and tail strong brine evaporative crystallization was compared. The propitiated proposal was selected. Postprocessed condensate water could be used as industrial water, and realized power plant water treatment system closetype circulating. There is not any water discharged. Waste water zero emission was realized.

Key words:
