摘　　要：选择天然沸石、钢渣和浮石作为原材料,以两两组合的方式按照不同比例形成组合骨料,通过静态试验考察其对氨氮、总磷的去除效果,优选出最佳组合。在对氨氮的去除效果中,天然沸石表现出显著优势,但除磷效果不佳。钢渣和浮石具有较好的除磷效果。按"氨氮+总磷"的综合去除效果评分排队,得到最佳组合形式为沸石与钢渣按3∶1的质量比组合。Choosing natural zeolite, steel converter slag and pumice as raw materials, according to the different proportion in the form of combination of two aggregate to form composite aggregate, on which removal efficiency of ammonia nitrogen and total phosphorus has been studied via static test. The best collaboration has been worked out. In the removal effect of ammonia nitrogen, natural zeolite show a distinct advantage, but the phosphorus removal effect is not good. While steel slag and pumice had good phosphorus removal effect. Queueing the comprehensive effect of ammonia nitrogen and phosphorus removal, the best combination was that zeolite combine with steel slag according to the quality ratio of 3： 1.
