摘　　要：目的:采用堆肥技术处理城市污泥以实现城市污泥的农用资源化进行了研究。方法:重点分析了污泥与粉煤灰混合厌氧堆肥过程中重金属铜稳定化的效果,分别按照污泥与粉煤灰质量比为1∶1;3∶1和4∶1进行混合,在常温下进行厌氧堆肥17d。结果:实验表明污泥与粉煤灰3∶1混合堆肥过程中铜的稳定化效果最佳。结论:堆肥过程有利于污泥的资源化利用。A composting process was investigated to realize the agriculture utilization of municipal sewage sludge in agriculture. Methods：It was focused that coal fly ash were co-composted with sewage sludge to evaluate its effect on heavy metal stabilization in anaerobic composting process. Sewage sludge mixed with ash as bulking agent at 1：1,3： 1 and 4：1 （w/w） respectively, and composted for 17 days in normal temperature. Results：The result showed that the optimal mixture rate was 3：1 （sludge： ash） in terms of the stabilization effects. Conclusion： Composting sludge process is conducive to the utilization of resources.
