The invention provides a method for recovering heavy metal contaminated soil through magnetotactic bacteria and chlorophytum comosum together. The magnetotactic bacteria and the heavy metal contaminated soil are mixed. The heavy metal contaminated soil mixed with the magnetotactic bacteria is irrigated. A magnetic field is set on the heavy metal contaminated soil, and the heavy metal contaminated soil containing the magnetotactic bacteria is collected, washed and filled back. The chlorophytum comosum is planted in the heavy metal contaminated soil primarily recovered through the magnetotactic bacteria and is removed overall after 90-100 days. The above steps are repeated until the content of heavy metal in the soil meets the safety standard. Compared with the prior art, the magnetotactic bacteria are easy to collect, and the chlorophytum comosum has high economic value besides recovering the soil. By means of the method, many kinds of heavy metal contaminated soil can be recovered at the same time, secondary pollution is avoided, and the method is suitable for treatment of large-area contaminated soil.
