Problems solved by technology

[0003] At present, biological treatment is used to treat heavy metals and absorb them through vegetation. However, after the plants are laid, they need to be watered frequently. Too little watering will affect the growth of plants, and too much watering will wash away the heavy metal soil.

Abstract

The invention discloses an ecological restoration bed for the heavy metal contaminated soil. The ecological restoration bed comprises a restoration pool, infiltration apparatuses, a water tank, herbaceous plants and woody plants, wherein the restoration pool is successively paved with a sandstone layer, a heavy metal soil layer, a wood chip layer and a common soil layer from bottom to top, the water tank is provided with a collecting pipe and a water return pipe, the collecting pipe is connected with the bottom of the restoration pool, the water return pipe is disposed inside the common soil layer, the upper end of each infiltration apparatus is disposed at the upper end of the common soil layer, the lower end of each infiltration apparatus is disposed inside the heavy metal soil layer, the herbaceous plants are planted on the surface of the common soil layer, and the woody plants are placed inside the heavy metal soil layer. By setting the wood chip layer, water can be stored inside the soil for the vegetation to absorb, the water storage capacity is large, the repeated watering can be avoided, a water flow on the surface of the common soil layer can be infiltrated into the internal soil through the infiltration apparatuses, the waste and loss of the water flow is prevented, the watering frequency is reduced, and the watering is more complete and thorough.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to an ecological restoration bed for heavy metal polluted soil. Background technique [0002] Soil heavy metal pollution refers to the excessive deposition of trace metal elements in the soil due to human activities, which exceeds the background value. With the continuous development of human society, heavy metal pollution has increasingly become a social concern. Heavy metals in the environment moderately stable, highly toxic to organisms, and a great hazard to human health. [0003] At present, biological treatment is used to treat heavy metals and absorb them through vegetation. However, after the plants are laid, they need to be watered frequently. Too little watering will affect the growth of plants, and too much watering will wash away the heavy metal soil. Contents of the invention [0004] The present invention aims at the above-mentioned deficiencies in the prio...
