  • 摘要: 在模拟氮磷废水中制备回收了一种鸟粪石负载硅藻土复合材料（MAP-D材料）用于土壤中锌的稳定。通过SEM-EDS、XRD和FTIR表征以及重金属各形态、土壤酸中和能力、土壤速效磷和酶活性测定等分析手段，探讨了MAP-D材料对土壤中锌的稳定化的影响。结果表明，MAP-D材料主要成分为负载有鸟粪石的硅藻土，当投加10%的MAP-D材料，稳定8周后，土壤中锌的可交换态含量降低56.9%，残渣态增加50.5%，土壤酸中和能力提升1倍，并提升了被锌抑制的过氧化氢酶和脲酶的活性。由此说明，MAP-D材料对土壤中的锌存在一定的稳定能力，进而实现废水中回收产品的资源化利用。
    Abstract: Struvite loaded diatomite composite (MAP-D material) was recycled in simulative wastewater and it was adhibited to the stabilization of Zn in contaminated soil. The stabilization effect of the material was explored through SEM-EDS, XRD and FTIR characterizations and the determination of heavy metal in various forms, acid neutralization capacity (ANC), soil available P and soil enzyme activities. The results showed that the main ingredient of MAP-D material was struvite loaded diatomite. After adding 10% MAP-D into the Zn contaminated soil in 8 weeks, the content of exchangeable Zn decreased by 56.9% while the residual Zn and ANC increased almost half and one times respectively. Also, the activities of catalase and urease, inhibited by Zn, were promoted. It’s indicated that MAP-D material has a certain stabilizing ability in Zn contaminated soil, which implements the utilization of recycling products in wastewater.
