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 x d) and initial filtration velocity 5 m/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%.
采用一种接触氧化与过滤分离间歇一体化生物反应器处理城市污水，该反应器装填组合填料。实验结果表明，在曝气时间60分钟、溶解氧2 - 3毫克/升、上层填料有机容积负荷2.4千克/(立方米·天)、初始过滤速度5米/小时的条件下，化学需氧量、氨氮和浊度的平均去除率分别达到90.6%、81.4%和96.7%，但该处理工艺除磷效果不佳，总磷平均去除率为60.1%。
