The results showed that both continuous and intermittent aeration system could implement completely autotrophic nitrogen removal.

结果表明，连续和间歇2种曝气方式均可实现单级自养脱氮，在进水氨氮浓度为160 mg/L左右，温度30℃±2℃，pH值7.8～8.2，HRT为2 d，DO为0.8～1.0 mg/L的条件下，连续曝气系统的氨氮转化率和总氮去除率分别达到80%和70%。

With respect to storage and disposal facilities for radio-active and other hazardous wastes, it is crucial to understand how contaminants move through the geosphere and how long-term performance of disposal facilities can be affected by geological and climatic changes over time.

至于放射性和其他有害废物的储存和处理设施，很关键的一条是必须了解污染物如何在陆界中移动，以及这些处理设施的性能会随着时间的推移，受到地质和气候的影响。
