The invention discloses a special water treatment agent FPAS-4 for treating papermaking wastewater and a preparation method thereof; the chemical structural formula of the product FPAS-4 provided by the invention is showed as the formula (1): n1+n2+n3<3. In the invention, ferrous sulfate is used as the raw material and dissolved in water; then, sulfuric acid and catalyst are added to the dissolved ferrous sulfate; an auxiliary agent is added to polymerize and compound the ferrous sulfate, the sulfuric acid and the catalyst, and finally the FPAS-4 product with brown viscous appearance is produced. For the FPAS-4 product provided by the invention, an organic high molecular compound is added during the treatment of the papermaking wastewater, thereby the COD in the wastewater is removed effectively, the organic pigment in the wastewater is removed efficiently, the flocculating settlement is conducted rapidly, and the effect of effective and rapid separation of the clear water is realized.
