White mud-gypsum method wet flue gas desulfurization method

The invention provides a white mud-gypsum method wet flue gas desulfurization method. The method comprises the steps that 1, white mud is taken, water is added for stirring, and white mud slurry is obtained; 2 the white mud slurry obtained in the first step is sent to absorption towers, flue gas to be treated is sent to the absorption tower, wet desulphurization is conducted, and treated flue gas and gypsum slurry are obtained. According to the white mud-gypsum method wet flue gas desulfurization method, the technology is simple, the white mud is adopted as desulfurizer, the desulphurization cost can be reduced, good desulphurization effect can be achieved, and meanwhile the effect of two-way control over the white mud and sulfur dioxide is achieved.
