| 摘 要： | 载体是生物膜移动术反应器(MBBR)工艺的关键影响因素,利用亲水化改性聚氨酯载体构建MBBR,用于城市污水的中试研究.反应器日处理能力为3～3.5 t.d-1,水力停留时间为7～8 h,在连续进水(进水COD 140～280 mg.L-1,NH4+-N 30～50 mg.L-1,总氮45～65 mg.L-1,总磷2.5～4.0 mg.L-1)条件下对改性载体的挂膜速度、有机物和氮的去除效果及不同温度下的污水处理特性进行了研究.140 d的试验结果表明在24～28℃时,载体上生物膜在6 d左右即可完成挂膜,并达到稳定的处理效果.COD、NH4+-N、TN和TP的平均去除率分别为70%、97%、70%和39%.随着水温逐渐降低到12℃左右,NH4+-N的去除率依然能达到97%,表明通过添加改性载体可以提高反应器低温条件下的硝化能力. |
