Abstract

The invention discloses a risk management and control and ecological restoration method for a metal mine pollution site. The method comprises the following steps: S100, leaching, identifying and classifying solid wastes and polluted soil of the metal mine pollution site; S200, carrying out corresponding treatment on different types of pollution media; and S300, carrying out ecological regreening treatment on the treated metal mine polluted site. According to the method, the solid wastes and the polluted soil in the metal mine polluted site are classified and identified according to related standards, and pollutants with different properties are classified and treated, so that the pollutants are prevented from polluting surrounding soil and water through surface runoff or leaching; recovery of the ecological environment of the metal mine and safety of surrounding human settlement and the ecological environment are achieved.

Description

technical field [0001] The invention belongs to the technical field of mine soil restoration, and in particular relates to a method for risk management and control of contaminated sites in metal mines and an ecological restoration method. Background technique [0002] With the rapid development of society and economy, the demand for non-ferrous metals is huge, and the mining, beneficiation and smelting activities of metal mines in my country are very active. The large-scale mining of metal mines has destroyed the original landscape ecosystem, and the ecosystem of the mining area has also been severely degraded; the discharge and storage of wastes generated by the mining, dressing, and smelting activities of metal mines have increasingly brought about a series of environmental problems. A large number of wastes containing heavy metals The water is washed and leached by rainwater, causing serious pollution of the surrounding soil and downstream water bodies, posing a great thr...
