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.
