摘要：
利用细菌氧化硫铁矿原理研制了PTX混凝剂，用于燃煤电厂高浊度、高pH灰水的处理。经四个电厂冲灰水处理试验表明，由PTX混凝剂处理后，SS<100mg/L,且沉降效果好、速度快，同时具有除氟、降低pH的效果，是一种多功能的复合水处理剂。
Abstract:
This paper presents a method to prepare PTX coagulant by py ri te to treat power plant high SS ash water. The experiment Shows the effect is satisfactory. it can decrease not only SS, but also pH and F-, and it is a coagulant with multifunctions.
