摘要:
采用高温好氧堆肥工艺,研究蘑菇渣、废白土为辅料的不同配比对城市污泥堆肥效果的影响。通过测定堆肥过程中温度、含水率、pH值、电导率、有机质含量、总氮含量、总磷含量、总钾含量、种子发芽率、重金属含量以及重金属各形态分布等指标,在确保堆肥产品达到安全农用要求的前提下,探讨不同辅料配比对污泥堆肥中重金属迁移转化的影响。结果表明,经过26 d的堆肥,各处理的污泥均达到腐熟程度,有机质含量、总养分含量、种子发芽率及重金属含量均符合园林绿化用泥质和农用泥质的各项指标;不同辅料配比对污泥堆肥效果影响明显,重金属镉(Cd)、锌(Zn)、铜(Cu)、铅(Pb)的形态分布总体上呈易迁移态向难迁移态转化,堆肥过程对Zn、Cu的形态转化影响最明显,其中以处理C(污泥 ∶蘑菇渣 ∶废白土=12 ∶10 ∶3)对污泥堆肥中重金属钝化的处理效果最佳。
