摘　　要：以实际造纸废水为原料通过烧杯小试试验,优选MBBR工艺中的填料类别并进行改性。结果表明,填料陶粒(Φ3~Φ5 mm)的效果最优;最优运行工况为pH≈7.9,填充率30%,此时COD去除率可提高约30%。对填料改性实验显示,Fe^(3+)覆盖改性填料比未改性填料COD的去除效果提高25%以上。The actual papermaking wastewater is used to pass a small test in a beaker,and the type of filler in the MBBR process is optimized and modified.The experimental results show that the effect of filler ceramsite(3-5 mm)is the best;the optimal operating condition is pH≈7.9,and the filling rate is 30%;the COD removal rate can be increased by about 30%.Experiments on filler modification show that the COD removal effect of Fe^(3+)-covered modified fillers is more than 25%higher than that of unmodified fillers.
