摘要
以硫酸法生产的钛白粉副产品七水硫酸亚铁为原料,以氧气、双氧水、臭氧作氧化剂,改变浓硫酸滴加速度、反应温度和反应时间来合成聚合硫酸铁铝。应用试铁灵逐时络合比色法测定铁溶液中聚合物的形态,结合其他性能测试,探索合成聚合硫酸铁铝的最佳工艺条件。经过反复实验证明,复合聚合硫酸铁铝生产周期短、成本低、经济效益高、设备投资少、产品无毒无害、絮凝效果好,是一种具有很好发展前景的絮凝剂。

ABSTRACT
In this paper,several oxidizers,oxygen,hydrogen peroxide, ozone etc., have been proposed to synthesize poly-ferric aluminous sulfate(shorted as PFAS) by different conditions such as dripping speed of concentrated sulfuric acid, reaction temperature and reaction time. The material,ferrous sulfate, derived from by-product of traditional production of titanium white. The active properties of poly-ferric aluminous sulfate were analyzed by means of Ferron & time colorimetry one by one, in order to conclude the optimal conditions for its further synthesis. The results show that the cycle of production is short, manufacture of ulant simple, total investment low, economic situation good, output “green”,sedimentation fast. In all, poly-ferric aluminous sulfate is promising wastewater ulant.
Keywords:PFAS ; Wastewater treatment ; Ferron & time colorimetry one by one
