| 摘 要： | 采用曝气生物流化床工艺,对NH4+—N质量浓度为90～140 mg/L,化学需氧量为130～200 mg/L,pH值为6～7的工业废水进行了处理。结果表明,在微生物加入量为130 mg/L,pH值为8,水力停留时间为5 d,曝气量为0.9 L/min的最佳条件下,NH4+—N去除率可以达到93%。处理后的水质达到GB 8978—96要求。

| Abstract: | The industrial wastewater with NH4＋- N mass concentration 90 - 140 rag/L, COD 130 - 200 mg/L,pH value 6 -7 was treated by aerobic biological fluidized bed process. The results showed that under the optimum condition of the dosage of immobilized microorganism 130 mg/L, pH value 8,hydraulic retention time 5 d, aeration flux 0.9 L/min, the NH4＊--N removal rate reached 93%. The quality of treated water could meet the requirement of GB 8978-96. |
