Abstract An aqueous aluminium iron polysilicate waste water cleaning agent is characterized by that it possesses the following chemical formula composite: [Na k Fe x Al y(SiOr)z(SO4)p.nH2O]m where all the subscript molar numbers are respectively: K is greater than or equal to 0.02 or less than or equal to 1.20, X is greater than or equal to 0.30 or less than or equal to 0.40, y is greater than or equal to 0.03 or less than or equal to 0.50, z is greater than or equal to 0.05 or less than or equal to 0.50, p is greater than or equal to 0 or less than or equal to 2.50, q is greater than or equal to 0 or less than or equal to 1.70, n is greater than or equal to 47 or less than or equal to to 55, m is greater than or equal to I and R is greater thanor equal to 2 or less than or equal to 4. It is made up by using ferrous waste slag, aluminium salt or aluminium refined liquor, hydrochloric acid, sulfuric acid or their mixed acid, industrial water glass and water as raw materials through the process of extraction, separation, activating and polymerization. It is suitable for treating alkali waste water of paper-making through the process of extraction, separation, activating and polymerization. It is suitable for treating alkaling waste water of paper-making through the process of extraction, separatino, activating and polymerization. It is suitable for treating alkali waste water of paper-making waste water and printing waste water.
