| 摘 要： | 为探讨微生物和生物炭联用对畜禽粪便堆肥过程中重金属钝化效果的影响,该文研究生物炭(花生壳炭、木屑炭、玉米秸秆炭)与复合微生物菌剂联用对重金属Pb、Cd形态转化及钝化效果的影响。试验结果表明:9个处理高温期维持天数均达无害化卫生要求,生物炭添加比例对堆肥过程中温度变化影响显著。对Pb的钝化效果最优处理是24%花生壳生物炭和1%的菌剂(T9),可交换态分配率较堆前下降16.32%,钝化效率为74.60%。对Cd的钝化效果最优的处理是24%木屑炭和1.5%的菌剂(T3),交换态Cd与堆前相比下降7.96%,钝化效率为58.13%。统计分析结果表明,重金属Pb、Cd的钝化效果与堆肥过程中平均pH值呈显著正相关,重金属Pb的钝化效果与堆肥过程中温度平均值呈显著正相关,重金属Cd的钝化效果与有机质降解率呈显著正相关。
