The invention relates to the technical field of tailing heavy metal pollution restoration and mine ecological restoration, and discloses a heavy metal tailing area pollution in-situ resistance control and efficient biological coverage restoration method which is an ecological restoration technology integrating solidification / stabilization restoration, barrier landfill and vegetation restoration. The method can solve the problem of simultaneous treatment of heavy metal polluted soil ecological restoration, mine pollution restoration and obstruction, can be used for restoration and ecological restoration of different heavy metal polluted soil and waste residue sites, and especially has a good effect on heavy metal restoration and ecological restoration of mine and smelting polluted sites.

This invention relates to a method for purifying water from deep, water-rich tunnels using a construction inclined shaft. The method includes the following steps: preliminary purification of the tunnel surface at the support face, including preliminary purification of the tunnel surface along the slope and against the slope; the installation of multi-stage sedimentation tanks within the main tunnel; the installation of water storage tanks and pumping stations; and further purification of tunnel wastewater in an external sedimentation tank. This method effectively removes tunnel construction wastewater through a preliminary purification system on the surface and through internal and external sedimentation and purification systems, ensuring a good construction environment. It has the advantages of being simple and practical, having good drainage and filtration effects, low pollution control costs, and enabling on-site recycling and reuse of wastewater with good overall performance.
