Environmental risk prevention and control integrated system and method for historical remaining tailing pond
The invention provides an environmental risk prevention and control integrated system and method for a historical remaining tailing pond, and relates to the technical field of environmental risk prevention and control of tailing ponds. The environmental risk prevention and control integrated system for the historical remaining tailing pond comprises a flood intercepting ditch, a blocking and anti-seepage layer group and a vertical anti-seepage wall, wherein the flood intercepting ditch is arranged around the tailing pond and is used for preventing rainwater outside the pond from scouring the tailing pond; the blocking and anti-seepage layer group is laid on the pond surface of the tailing pond and is used for blocking the rainwater from vertically seeping into the tailing pond; and the vertical anti-seepage wall is arranged at an underground water leakage path of the tailing pond and is used for blocking underground water from leaking. According to the environmental risk prevention andcontrol integrated system for the historical remaining tailing pond, a flood intercepting ditch structure around the pond, a vertical anti-seepage structure and a horizontal blocking structure are combined, the concentration of cyanide in the anti-seepage wall does not exceed the standard concentration after treatment, the rainwater outside the pond cannot scour the tailing pond, underground water pollutants are blocked on the inner side of the vertical anti-seepage wall, and the water quality of the underground water at the downstream of the tailing pond can be remarkably improved.
本发明提供了一种用于历史遗留尾矿库的环境风险防控集成系统及方法，涉及尾矿库环境风险防控技术领域，本发明提供的用于历史遗留尾矿库的环境风险防控集成系统包括围绕尾矿库设置的截洪沟，截洪沟用于防止库外雨水冲刷尾矿库；铺设于尾矿库的库面上的阻隔防渗层组，阻隔防渗层组用于阻隔雨水垂直下渗至尾矿库；在尾矿库的地下水外泄路径处设置的垂直防渗墙，垂直防渗墙用于阻隔地下水外泄。上述用于历史遗留尾矿库的环境风险防控集成系统将环库截洪沟结构+垂直防渗结构+水平阻隔结构相结合，治理后防渗墙内氰化物浓度不超过标准浓度，库外雨水无法冲刷到尾矿库，且地下水污染物被阻隔在垂直防渗墙内侧，可显著改善尾矿库下游地下水水质。
