The existing nano ceramic material is mainly used for farmland heavy metal remediation in two ways: one is to directly spread the granular material in the farmland, mix it with the soil evenly through normal plowing, the material is to lattice the heavy metal ion in the nanometer aperture of the material itself through a series of reactions in the soil, the affinity and the adsorption force of the farmland passivation heavy metal material to the heavy metal are thousands times of the plant root system, under the condition that the material exists, the heavy metal ion is mainly migrated to the material and bonded. Although the method has convenient treatment and good effect, the nano ceramic material adsorbing heavy metals is not easy to recover, and can be stored in soil for a long time, and certain influence can be generated on farming after a large amount of nano ceramic material is absorbed. The other method is to treat the surface layer of the polluted farmland by adopting equipment, after clean irrigation water enters the farmland, add an environment-friendly heavy metal activator, leach part of effective heavy metal from plowed soil, enable the effective heavy metal to enter downstream treatment equipment along with water, and then adsorb and recycle the heavy metal by using materials so as to thoroughly remove the heavy metal in the farmland. Although the method can not cause secondary pollution and can quickly and efficiently and permanently remove the heavy metals in the farmland, the method has the defects of large engineering quantity, high equipment cost and high energy consumption.
