摘　　要：含有重金属添加剂肥料的大量使用,导致畜禽粪便中重金属含量增加,造成土壤重金属污染。研究表明,好氧堆肥可以降低畜禽粪便中重金属的生物有效性,使其向可氧化态和残渣态转变,减少畜禽粪便对土壤的重金属污染。通过添加不同种类的物理、化学、生物钝化剂来增强堆肥钝化重金属能力,有利于提升堆肥品质及安全性。阐述了好氧堆肥过程中重金属的形态和重金属钝化剂的研究进展,对好氧堆肥重金属钝化剂研究进行了展望。Heavy metal additive containing fertilizer is widely used,which leads to the increase of heavy metal content in livestock and poultry manure,resulting in serious soil heavy metal pollution.Studies have shown that aerobic compost can reduce the bioavailability of heavy metals in livestock manure,transform it to oxidizable state and residue state,and reduce the heavy metal pollution of soil from livestock manure.By adding different kinds of physical,chemical and biological passivating agents to enhance the passivating ability of compost,it is beneficial to improve the quality and safety of compost.The forms of heavy metals and the research progress of heavy metal passivators in aerobic composting were reviewed.Finally,the research of heavy metal passivators in aerobic composting was prospected.
