【摘要】 利用Al3 + 、Fe3 + 的共聚合特性和硅酸的盐效应机制 ,选择廉价而广泛的原料 :工业用的AlCl3 、废铁屑或硫铁矿提取硫酸后的废渣、工业用水玻璃以及工业盐酸 ,在常温常压下聚合出的PSAFC废水处理药剂 ,对贵阳棉纺厂的几种印染废水在实验室条件下进行处理 ,处理效果比目前市场上普遍使用的碱式氯化铝 (PAC)的效果要好更多还原

【Abstract】 The copolymeric characteristic of Al 3+ and Fe 3+ and the salt effects of silicic acid are made use of. Cheap raw materials,such as industrial AlCl 3,iron scrap or iron slag from pyrites after sulfuric acid has been extracted,industrial water glass and industrial hydrochloric acid are used to polymerize a kind of new coagulant—Polysilicic Acid Aluminium Ferric Chloride(PSAFC) under normal temperature and atmospheric pressure conditions. Some sorts of the printing and dyeing wastewater in Guiyang Textile Factory are treated in laboratory and have got a better efffect,compared to current coagulant of PAC.更多还原
