提出了一种改性聚合硫酸铁的生产新技术 ,采用一种新型的催化剂并添加少量高效的改性剂 ,可以显著地提高产品的盐基度 ,加快反应过程的进行 ;还讨论了诸如反应温度、催化剂、改性剂等对反应速率及对产品性能的影响 ,并对产品的絮凝性能进行了测试 A new technology for the production of modified polyferric sulfate was proposed. Using a new type of catalyst and adding a small amount of high-efficient modifier can significantly increase the basicity of the product and speed up the progress of the reaction. Other methods such as reaction Temperature, catalyst, modifier on the reaction rate and the impact on product performance, and the flocculation performance of the product was tested
