Through lots of tests, the new technology of preparing the polymeric ferric aluminum silicate sulfate by using the waste-acid of Ti02-industriy and the coal fly ash has been designed. The highest Al-acid stripping rate can be achieved by the waste sulfate acid under boiling degree for 1. 5h when the mass ratio between NaCl and Coal Fly ash is 0. 05:1, as well as that between Coal Fly ash and Waste Acid ratio is 1:10. By means of the oxidation-polymerized reaction under 40-50*C and normal pressure, using NaNCkas catalyst and air as oxidation, the polymeric ferric aluminum sulfate can be obtained. The poly-silicic acid is polymerized with soluble glass in the optimum conditions of pH=5-6 and the concentration of Si02 is about 3%. The inorganic high molecule coagulant of PFASS is synthesized with the poly-silicic acid into the solution of polymeric ferric aluminum sulfate.
