Passivator used for remediation of heavy metal polluted farmland soil, and preparation and application of same

The invention relates to a passivator used for remediation of heavy metal polluted farmland soil, and preparation and application of same. The passivator is composed of, by mass, 60-70% of bio-charcoal, 20-30% of plant ash, and 10-20% of sepiolite powder. The passivator is prepared by preparing straw black charcoal through burning, sieving the plant ash and the sepiolite powder, weighting the straw black charcoal, the plant ash and the sepiolite powder according to mass ratio and mixing the components. The application includes: cleaning to-be-remediated land surface, uniformly spreading the passivator on the soil surface and ploughing the soil over to ensure that the passivator and the heavy metal polluted farmland soil are fully mixed. The passivator is strong in adsorption effect and canchange the forms of the heavy metals in soil. Under cooperation of the components, effective state content of heavy metals is reduced, and fertility of the soil is improved, thereby increasing yieldof crops to certain degree and improving physical and chemical properties of the farmland soil; the passivator is environment-friendly and is free of influence on cultivation and agricultural production due to in-situ remediation, is prepared from accessible and extensive raw materials, and has an extensive application prospect.
