Taking water system of limestone-gypsum Wet Flue Gas Desulfurization (WFGD) device as object of study. First, this paper carries on the analysis to the quality of desulfurization wastewater, then in view of the water quality characteristic of desulfurization wastewater the paper proposes the materialized treatment method, and conducts the experimental study. In the materialized method selecting polymeric aluminum ferric silicate sulfate (PAFSS) as the coagulant, then using the orthogonal experiments determine PAFS best text condition under remove of the sulfide, the fluoride and the COD by PAF...
