摘要
介绍了纯氧曝气的生化机理、应用领域、供氧方式、污泥性能等以及它与普通空气曝气相比在技术、经济方面显示出的优越性。随着纯氧曝气的发展和国家新标准增加了脱氮除磷方面的排放要求,使得纯氧曝气在城市污水处理老厂的改造和新厂的建设中具有很好的前景。
The article introduces the biochemical mechanism,application field,methods of oxygen supply, characteristic of activated sludge etc and the superiority of pure oxygen aeration system compared with air aeration system in economy and technique,with the development of pure oxygen aeration and new discharge standard restriction on nitrogen and phosphorus removal,it shows nice prospect in old plant transformation and new plant construction for municipal sewage treatment.
