| 摘 要： | [目的]为城市污水处理厂的优化脱氮和节能运行提供参考。[方法]采用有效容积为240 L的中试Carrousel氧化沟处理模拟生活污水,研究溶解氧、进水COD负荷和进水氨氮负荷对Carrousel氧化沟同步硝化反硝化的影响。[结果]综合氨氮和总氮的去除率,能够满足同步硝化反硝化的最佳溶解氧浓度为1.0 mg/L,最佳进水COD负荷为0.25 kg COD/（kgMLSS.d）。较小的进水氨氮负荷有利于同步硝化反硝化过程的进行。[结论]溶解氧是控制氧化沟内发生同步硝化反硝化过程的最关键的因素。进水COD负荷对同步硝化反硝化过程的影响主要是体现在进水COD负荷对实现较好硝化效果的限制。
