Method for comprehensively utilizing low-concentration heavy metal-containing soil improvement and repairing damaged soil by plants after detoxification of contaminated field

The invention relates to a method for comprehensively utilizing low-concentration heavy metal-containing soil improvement and repairing damaged soil by plants after detoxification of a contaminated field. The method comprises the following steps of: conveying of low-concentration soil after heavy metal-containing soil is detoxified, sludge and pulverized fuel ash; principal fermentation, mixing of various ingredients; primary fermentation; static state of post-fermentation (secondary fermentation); uniform turning (aerobic and anaerobic) fermentation; conveying of improved soil; and vegetation repairing (woody and herbaceous plants) planting for the contaminated soil. In the method, a modifier is added for modification, so that the content of heavy metals in the soil is reduced, the structure and pores of the damaged soil are repaired, and the permeation and air permeability of the soil are improved; and organic matters and other noxious matters in sludge and soil are decomposed and degraded in a certain condition by utilizing microbes in the sludge to reduce volume weight and compactness, so that the improved soil forms a substance similar to humus soil to serve as a biochemical process of the improved soil and fertilizer. According to the method, the planted vegetation growing environment of the land which uses the improved soil as a soil base material is ensured, so that the waste is used to treat waste, and the comprehensive utilization is improved.
