Ecological remediation device for polluted soil of coal mining wasteland

Abstract

The invention discloses an ecological remediation device for polluted soil of a coal mining wasteland. The ecological remediation device for the polluted soil of the coal mining wasteland comprises aremediation liquid box, a lower chamber, a grid plate, a first vertical partition, a communication hole, a running water tube, a valve, an upper chamber, an end plate, a second vertical partition, a liquid suction pump, a main liquid suction tube, a liquid suction branch tube, a main liquid delivering tube, a collecting device, remediation plants, a jacket, a liquid delivering branch tube, a liquid delivering device and a protecting layer. The ecological remediation device for the polluted soil of the coal mining wasteland is reasonable and simple in structure; the collecting device and the liquid delivering device are favorably inserted in different positions in the polluted soil of the coal mining wasteland, and therefore, the construction speed is greatly increased; by the liquid delivering device, remediation liquid in the remediation liquid box is favorably uniformly delivered in soil to remediate the soil, and the collecting device favorably sucks the remediation liquid in the soil into the remediation liquid box through the liquid suction pump so that the remediation liquid can be recycled; and a chemical agent feeding opening is formed in the left side of the end plate, thus, a remediation chemical agent is favorably fed into the remediation liquid box, and thus, a circulating remediation effect of the remediation liquid is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to an ecological remediation device for polluted soil in abandoned coal mines. Background technique [0002] With the development of society and economy, people's requirements for the environment are getting higher and higher, and relevant laws, regulations and norms on the remediation of heavy metal-contaminated soil have been issued. The market demand for remediation of heavy metal-contaminated soil is increasing. In addition to meeting the repair standards, the requirements for repair cycle, repair cost, and effect durability are also getting higher and higher. Usually, remediation devices are used to manually remediate polluted soil or phytoremediation technology is used to carry out ecological remediation of heavy metal-contaminated soil. However, the existing ecological remediation devices for polluted soil in coal mine wasteland have relatively poor remediation effec...
