在化学沉淀法处理高浓度氨氮废水的基础上,选择活化后的黏土、沸石和粉煤灰作为晶种投加到反应器中.然后从氨氮的去除率、生成晶体的粒型、粒径和组成4个方面分析不同晶种的影响.从而得出结论:投加晶种可明显提高氨氮的去除率,但对形成大粒径晶体的影响不大.

On the basis of treating highly concentrated ammonia-nitrogen wastewater by chemical precipitation process,activated clay,activated zeolite and activated coal ash have been chosen as crystal seeds.Then,the effects of ammonia-nitrogen removal rate,particle type,particle diameter and component are analyzed.The results show that adding crystal seed can improved ammonia-nitrogen removal rate obviously,but does not have much effect on the formation of big particle diameter.
