摘　　要：以尾矿、煤粉、粘土等为原料,经配料、成球、筛分、焙烧等工序制成粒径4-6mm、抗压强度8.31MPa、堆积密度797kg/m3、空隙率40%的球形生物填料。通过模拟曝气生物滤池,经过3个阶段的实验后,结果表明：该填料具有较强的吸附性能,运行一段时间后对COD和NH＋4-N的去除率均可达到80%以上。并且此填料的原料来源广、成本低、制作工艺简单,具有广阔的应用前景。The spherical biological packing was made from tailings,coal powder,clay through the process of propor- tion,bailing,screening and calcination. Its particle size, compressive strength, bulk density, void fraction were 4-6mm, 8.31MPa,797kg/m^3 ,40% respectively. The results showed that the packing had stronger adsorption performance, after a period,the removal rate of COD and NH＋ N both can reach above 80%. And the packing will have a broad application prospect because of wide raw material sources,low cost,simple manufacturing process.
