▎ 摘　　要

NOVELTY - Non-saturated heavy metal pollutant transfer device comprises a water supply system for supplying water to the infiltration column assembly. A permeable column assembly is filled with the non-saturated heavy metal pollutant. The temperature sensor (8) and moisture sensor (9) are installed on the infiltration column subassembly. The temperature sensor is connected with a temperature collecting instrument (10). The moisture sensor is connected with a water collecting instrument (11). The infiltration component is connected with a constant temperature control system. USE - Non-saturated heavy metal pollutant transfer device useful in the field of pollution prevention, using migration rule of the characteristic pollutant and graphene oxide to purify the heavy metal polluted soil, researching static adsorption-desorption mechanism of heavy metal ion, belonging to heavy metal pollution field. ADVANTAGE - The device: utilizes the graphene oxide to purify the heavy metal polluted soil; can explore static adsorption-desorption mechanism of heavy metal ion; is belonging to heavy metal pollution field; utilizes graphene oxide as adsorbent; and is capable of absorbing heavy metal ions in the porous medium. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a migration experiment method based on the non-saturated heavy metal pollutant transfer device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the non-saturated heavy metal pollutant transfer device useful in the field of pollution prevention. 1Water storage bottle 2Top cover 3Flange 4Powder soil 5Permeate pipe 6Measuring point through hole 7Filtering liquid outlet 8Temperature sensor 9Moisture sensor 10Temperature collecting instrument 11Water collecting instrument 12Constant temperature water bath box 14Base
