The invention relates to a method for repairing heavy metal polluted soil based on a permeation absorption wall. The method specifically comprises the steps of: construction of the permeation absorption wall, soil leaching, heavy metal enrichment, regeneration of the permeation absorption wall, and heavy metal recovery. Compared with the prior art, the used permeation absorption wall is a movable assembled permeation absorption wall built by absorption bricks, which are produced through a forming process by adding a binding agent in such absorption materials as fly ash, clay and molecular sieves; the permeation absorption wall is spliced as cuboids with different specifications; and the method is combined with a chemical leaching method to exert the effects of leaching, absorption and heavy metal enrichment, can be used for a soil ectopia repair engineering technology, protects underground water, and shortens the soil repair treatment period. The method combines a physical method with a chemical method, is cheap in raw materials, easy to obtain the raw materials and low in operation cost, treats wastes by wastes, is short in soil treatment period, is obvious in energy saving advantages, and is broad in application prospect.
