Abstract

The invention discloses a soil organic matter-heavy metal pollution integrated repair system and method. The system comprises a material inlet, thermal analysis equipment, leaching equipment and a material outlet, the thermal analysis equipment comprises a motor, a transmission gear, a horizontal drum and a heating device, the transmission gear is arranged at the end of the drum, the motor drives the transmission gear so as to drive the drum to rotate, the heating device is arranged on the periphery of the drum, and a chimney is arranged on the drum; the leaching equipment comprises a leaching body unit and a leaching liquid batching unit, a plurality of nozzles connected with the leaching liquid batching unit are arranged at the upper end in the leaching body unit, the material inlet is connected with a feeding port of the drum, a discharging port of the drum is connected with a feeding port of the leaching body unit, and the material outlet is arranged at the bottom of the leaching body unit. By the system, organic matter pollutants and heavy metal pollutants in soil can be removed at the same time; the system adopts continuous process, realizes centralized disposal and is small in occupied area, so that cost of soil repair is lowered greatly.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to an integrated remediation system and method for soil organic matter-heavy metal pollution. Background technique [0002] In recent years, my country's heavy metal pollution alarm bells have sounded frequently. From the "blood lead incident" to the "cadmium rice incident" that shocked the whole country, if the heavy metal pollution in the soil is allowed to continue, according to the current development trend, the heavy metal pollution in the soil will be a few years later. The accumulation will be further intensified, and once the heavy metal content reaches a pathogenic level, the situation will get out of hand. The existing soil remediation technology not only has high construction and operation costs, but also complicated operation methods, and the remediation effect is not high. [0003] The remediation of organic-contaminated soil has always been a hot s...
