摘　　要：在恒温静态条件下,对污水处理厂进出水中化学需氧量与氨氮浓度的变化趋势进行测定与分析。结果表明,污水处理厂进水中化学需氧量降解速率大于氨氮,经生化处理后的出水样品中,化学需氧量不再降解,而氨氮仍存在部分降解能力。The change and analyzed under COD is faster than degradation trend of to degrade. trend of COD and ammonia nitrogen concentration in sewage treatment plant were determined static state at constant temperature. The resuhs showed that the degradation rate of influent the degradation rate of influent ammonia nitrogen in sewage treatment plant. However, the effluent COD is end completely and only a small part of effluent ammonia nitrogen is continue to degrade.

关 键 词：污水处理厂 降解 化学需氧量 氨氮
