摘　　要：天然河流水质受到污染,但水能依然存在且可以利用。研究了利用水体的势能进行大气复氧的方法,并将其引进污水生物处理领域。被污染的河水通过势能增氧生态床法进行原位生态修复后,其水质可达到地表水Ⅲ类标准,而且大大降低了污水处理费用。该研究革除了鼓风曝气进行大气复氧(利用动能),突破了污水生物处理的"障碍",充分发挥利用水体势能进行大气复氧的运行费用低的优点,开辟了水能利用的新领域。Even though the water quality in natural river is polluted, the water power still exists and can be used. So we propose a method for air aeration using water power and appliedit to the aspect of sewage ecological treatment. The water quality standard will reach Ⅲ classification for surface water and the direct operation cost of sewage treatment will be greatly reduced in the polluted river water. The method abolishes the blast aeration （kinetic energy utilization）, breaks down ＂The Sound Bartier＂ of sewage ecological treatment and brings the advantage of the water power utilization with cost low into full play.
