| 中文摘要 |
| 针对一种采用组合填料的接触氧化过滤一体化生物反应器，进行了以间歇方式处理城市污水的试验研究.结果表明，在曝气时间为60 min，DO为2～3 mg/L，反应器上部填料层容积负荷率(以COD计)为2.4 kg/(m3·d)，生物滤床初始滤速为5 m/h时，反应器出水COD、NH+4-N、浊度的平均去除率分别为90.6%、81.4%和96.7%，但TP去除效果欠佳，平均去除率为60.1%. |
| 英文摘要 |
| An intermittently integrated bioreactor of contact oxidation and filtration separation was applied to treat municipal wastewater，which was packed with combination medium. Experimental results show that at the condition of aeration time 60 min，DO 2-3 mg/L，organic volume load of upper packing 2.4 kg/(m3·d) and initial filtration velocity 5m/h，the average removal rates of COD，ammonia nitrogen and turbidity reach 90.6%，81.4% and 96.7% respectively，but this treatment process seems to be not available in phosphorus removal. The average removal rate of TP is 60.1%. |
