Abstract

Abstract

In this paper, a series of new inorganic polymer coagulants (Polymeric Aluminum Ferric Chloride Sulfate, PAFCS) were prepared by using waste hydrochloric acid and chlorinated tail gas absorbing liquid from by-products of the production of titanium dioxide, in combination with industrial aluminum hydroxide and ferrous sulfate heptahydrate, under the conditions of hydrogen peroxide catalytic oxidation. The appearance of the prepared PAFCS was a reddish-brown transparent liquid with a density of 1.39 to 1.43 g/cm³, and the total content of iron and alumina (TFe + Al₂O₃) was ≥10.5%, which could be used as coagulant for water treatment. The PAFCS prepared in this paper were used to treat landfill leachate biochemical tail water, in which the removal rate of COD reached 68.51%, which was superior to the traditional coagulant polymeric ferric sulfate (PFS). At the same time, this work provides ideas for solving the problem of resource utilization and clean production of by-products in the production process of titanium dioxide by chlorination method in China.
