摘　　要：为减少堆肥过程中所产生的臭气污染,探讨了高氮污泥堆肥过程中氨气的产生规律及影响因素。改变堆肥原料的C/N比、含水率及温度,观察氨气产生速率及浓度的变化。结果表明:氨气产生速率峰值约出现在第4天,在第15天后基本趋近于0;当碳氮比达到31,初始含水率为55%,环境温度为25℃时,氨气产生速率及浓度较小。To reduce odor produced in the composting process, the law the factors were discussed. C to N ratio, temperature, moisture content were changed in the composting process to regulate the release and the of ammonia production and of the composting material concentration of ammonia. The results showed that ammonia production rate reached the peak at the 4th day, and at the 15th day dropped to nearly zero. When the C to N ratio was relatively high at 31, the initial moisture content was 55%, the ambient temperature was 25 ℃, the production rate and concentration of ammonia was smaller.
