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.
