高浓度氨氮废水好氧反硝化反应的基本条件

文章通过室内实验,对高浓度氨氮废水(垃圾渗滤液)间歇曝气,在只存在有机碳、无机氮的条件下进行好氧反硝化脱氮研究。实验结果表明:垃圾渗滤液中存在好氧反硝化土著微生物菌落;发生好氧反硝化的基本条件为在溶解氧充足的条件下间歇曝气;碳源不仅是厌氧反硝化所必须的,同样也是好氧反硝化的必要条件。

Aerobic Denitrification Process of Sewage with High-concentration of Ammonia Nitrogen

Intermittent aeration experiments were carried out on sewage with high-concentration of ammonia nitrogen(leachate)in the laboratory.Aerobic denitrification experiments were also conducted under the conditions of organic carbon and inorganic nitrogen.The results showed that aerobic denitrification bacteria would become dominant microbe;If dissolved oxygen was rich in the leachate,intermittent aeration would be a basic approach for aerobic denitrification;Organic carbon is not only the indispensable constituent for anaerobic denitrification,but also for aerobic denitrification.
