摘要: Abstract To reduce nitrous oxide (N 2 O) emissions from fill-and-draw type activated sludge units treating swine wastewater, the N O emission was compared between continuous aeration process (conventional process) and intermittent process. About 35% of influent nitrogen emitted as gas using conventional under 0.5 kg·m −3 ·d −1 BOD loading. 60% duing first hours started just after daily charging. On other hand, only less than 1% during
