摘　　要：以粉煤灰为原料制取净化DDNP废水用粉煤灰基混凝剂。由实验可知,最佳工艺参数为240目粉煤灰10 g,加入30%的硫酸18 mL,在50℃条件下反应2 h,制备的粉煤灰混凝剂处理DDNP废水具有较好的效果;同时,粉煤灰比表面积大、吸附性强;且来源广泛,费用低,因此粉煤灰是制备净化DDNP废水混凝剂的一种理想原料,达到以废治废的目的。The method of making coagulant with fly ash used in cleaning DDNP wastewater was studied in this paper. The optimal technical parameters were obtained by experiments. The coagulant produced of 10 g fly ash of 240 mesh reacting 2 hours with 18 mL sulfuric acid of 30% concentration in the temperature of 50 ℃ shows the best effect in cleaning DDNP wastewater. Furthermore, fly ash is easy and cheap to get, so it is an ideal material to make coagulant.
