Abstract:
A soil heavy metal composite passivator and its preparation method, use method and application. The passivator is a powder particle obtained mainly by mixing modified palygorskite, biomass charcoal, quicklime and fungus residue in a mass ratio of 1:(0.3˜0.5):(0.5˜0.8):(0.2˜0.4), with an average particle size of 0.5˜1 mm. The invention further provides preparation and use methods for the above soil heavy metal composite passivator. The soil heavy metal composite passivator according to the invention can effectively passivate heavy metal pollution in farmland soil and reduce bioavailability of various heavy metals in soil so as to recover ecological and industrial functions of the soil and improve crop quality. Material selected in the present invention are safe and environmental-friendly, realized “waste control by waste itself”, have long service life, and do not cause secondary pollution to soil.

Claim (Index 1):
A soil heavy metal composite passivator obtained mainly by mixing modified palygorskite, biomass charcoal, quicklime and fungus residue uniformly in a mass ratio of 1:(0.3\u02dc0.5):(0.5\u02dc0.8):(0.2\u02dc0.4).
