摘　　要：粪污还田过程中,将大量重金属施入土壤,威胁人体的生命健康及土壤生态环境的平衡。通过合理地调控堆肥过程中水分、供氧、温度、pH值及添加剂等因素,可以促进堆肥化进程、加快堆肥腐熟、促进重金属与有机质之间的相互结合,从而降低重金属的生物有效性,这为降低重金属的危害提供了新思路。In the process of manure returning to the field,a large amount of heavy metals are applied into the soil,which threatens human health and the balance of soil ecological environment.Through the reasonable control of water,oxygen supply,temperature,p H value and additives in the composting process,the composting process can be promoted,the composting maturity can be accelerated,and the combination of heavy metals and organic matter can be promoted,so as to reduce the bioavailability of heavy metals,which provides a new idea for reducing the harm of heavy metals.
