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.

本论文通过大量的试验，研究开发出了用粉煤灰及钛白废酸制取聚合硫酸硅酸铁铝的新工艺，其最佳工艺条件为：于沸点温度，以NaCl为助溶剂(NaCl与粉煤灰质量比为0.05：1)，以钛白废酸浸取粉煤灰(固液比为1：10)中的铝1.5小时，最大浸取率可达40％；经过滤洗涤后，调节滤液pH至2.0左右，以NANO_2为催化剂(NaNO_2用量为滤液中FeSO_4·7H_2O量的3％)，空气为氧化剂，于40-50℃进行常压催化氧化反应，制取聚合硫酸铁铝，催化氧化时间为2小时；将工业水玻璃稀释至3％左右，调节其pH于5-6，室温下制备活性聚硅酸；将活性聚硅酸与聚合硫酸铁铝按照一定比例复合，经熟化，即制得新型无机高分子混凝剂PFASS。
