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。

Recently, using solid clay brick is gradually prohibited, so the new wall material is required to fill up the new architecture. Many sections research on this field, using fly ash to develop new building materials is the mostly adopted method, among the new building materials, fly ash foamed concrete is a noticeable one because of its outstanding merits such as light weight, heat preservation, sound insulation and good resisting earthquake. Using fly ash to develop foamed concrete can not only become fly ash into resources, but also provide a new kind of building materials for the innovation of wall materials, which has good economy and society benefits.

近年来，由于墙改&禁实&政策的实施，市场急需新的墙体材料来填补新建筑所需，许多单位相继开展了各有关研究，综合利用粉煤灰研制开发新型建材逐渐成为了主流，其中多孔混凝土特别是粉煤灰发泡混凝土，正以它突出的轻质、保温、隔音、抗震效果好等优点，成为一种引人注目的建筑材料，利用工业固体废弃物粉煤灰研制发泡混凝土不仅能实现粉煤灰的资源化，而且还可为墙体材料的改革提供一种新型建筑材料，具有较好的经济效益和社会效益。

Under the condition of organic chlorine content 0.25-0.53% of the input refuse and the furnace temperature range of 939-1,033℃, rise with furnace temperature, the proportion of lead transferred into gaseous is increased, and the lead content of fly ash and reaction ash increases obviously. It can be expressed as y1 =11.051x－9824.9 and y2 =26.729x－23680, where x is the furnace temperature, y1 and y2 are the content of lead in fly ash and reaction ash.
