| 摘 要： | 采用自行设计的试验装置,研究了生物接触氧化技术在景观水体抽出处理回用中的应用,探讨了氨氮的去除规律。试验内容包括生物膜的挂膜及驯化;在不同水力停留时间、曝气强度下,氨氮的去除效果及三氮的变化情况;最后研究了水温对氨氮去除率的影响。试验结果表明,在最佳试验条件下,即曝气强度为0.030 m3/h,水力停留时间为3 h时,氨氮的去除率可以达到90%以上,COD的去除率达到43.5%,并且没有出现亚硝态氮累积的问题。该技术对温度的适宜性较好,即使温度在5~8℃,对氨氮也可以保持较高的去除率,满足景观水体水质要求。当温度小于5℃时,系统氨氮的去除率迅速减小。

| Abstract: | The application of biological contact oxidation in the recycle of landscape water is researched with self-designed experimental facility and the law of ammonia removal is discussed.The research includes biofilm colonization and domestication,the removal efficiency of ammonia and changes of ammonia-nitrite-nitrates under different HRT and aeration intensity.At last,the influence of water temperature on the removal effiency of NH3-N is studied.The result shows that at the optional condition that HRT is 3 h,an... |
