摘　　要：研发了一种跌水拔风充氧装置,跌水板为单板交替式,板上铺挂组合填料。结果表明,充氧效果随跌水高度和跌水流量的增加而提高,污水在跌水拔风充氧的同时得到处理。当跌水流量6 m L/s,跌水高度120 cm时,COD平均去除率42%,氨氮平均去除率34%。waterfall and ventilation oxygenationdevice was developed,and waterfall platewas a single plate alternating spreading with combine media. The experimental results showed that, the oxygenation effect was enhanced with the increase of waterfall height and waterfall flow. Sewagecould be oxygenated and treated at the same time. When the waterfall flow was 6 mL/s and waterfall height was 120 cm, the average removal efficiency of COD and NH3-N was 42% and 34%, respectively.
