In the prior art, the effluent of the flocculation tank automatically flows into a clarifier, flocs in the wastewater further grow up in the clarifier and are precipitated and separated through an inclined plate (or an inclined pipe), and the upper clear water automatically flows into a clear water tank after the pH value of the upper clear water is adjusted to 6-9 by adding acid. And conveying the sludge of the clarifier to a filter press for filter pressing. The prior art can basically reach the discharge standard, but a large amount of chloride ions and sodium ion salts in the desulfurization wastewater are discharged along with the treated water, so that the resource waste is caused.
With the continuous implementation of economic development modes of energy conservation, emission reduction and green and low carbon, how to reduce the emission of greenhouse gases such as carbon dioxide and the like becomes a difficult task for a long time in the future, and coal-fired power serving as one of main emission industries of carbon dioxide greenhouse gases also becomes an important factor influencing the sustainable high-quality development of the carbon dioxide greenhouse gases.
