Abstract

The invention relates to a polluted soil heaping extraction-injection combined repairing device and method. The device comprises a water collecting pipe which is used for being arranged in polluted soil; the water collecting pipe communicates with an extraction pump; the water collecting pipe also communicates with a medicine injection pump; and the medicine injection pump communicates with a medicament container for accommodating leacheate. The device has the following beneficial effects: the aims of efficiently leaching soil and removing pollutants are fulfilled by extracting and injecting the soil leachate into the polluted soil heap, and the investment of leaching equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of remediation of organic polluted soil in environmental protection, in particular to a chemical washing device and method for polluted soil. Background technique [0002] In recent years, the problem of soil and groundwater pollution has become increasingly prominent, threatening the human body and the surrounding environment, and even endangering life in severe cases. The situation of heavy metal pollution in soil in our country is serious, which has become an important issue restricting the harmonious development of our economy, society and people's life quality. The research on the restoration of polluted soil is the need of building an environment-friendly and resource-saving society and strengthening the protection of natural ecological environment. However, the steps of leaching restoration in the existing soil treatment are complicated, and the leaching effect is poor. Contents of the invention ...
