Waste sewage treatment method in mineral exploration process

Abstract

The invention discloses a waste sewage treatment method in the mineral exploration process. The waste sewage treatment method comprises the following steps: I, studying and utilizing the vantage ground under a well, selecting an appropriate large-capacity worked out section as a natural filtering tank and a settling pond, and treating mine wastewater so as to circulate the mine wastewater under the well; II, according to mine water quality characteristic analysis, performing simple purification and utilization on mine water if pollutants such as heavy metals which can do great harm and are hard to remove do not exceed standards, removing suspended solids and bacteria in the mine water, and neutralizing acid mine water so as to meet mine operation water use requirements; and III, performing wastewater diversion from clean water. By adopting the waste sewage treatment method in the mineral exploration process, the large-capacity worked out section has settling and filtration functions, meanwhile the quality of a water body can be improved through a self-cleaning function to a certain extent, and high-temperature wastewater which is discharged in a short term can be cooled.

Description

technical field [0001] The invention relates to a method for treating mineral waste water, in particular to a method for treating waste water during mineral mining, and belongs to the technical field of mineral waste water treatment. Background technique [0002] The large-scale mining process is bound to be accompanied by the utilization of a large amount of water resources and the subsequent excretion process. These processes will change the path of the water cycle and the quality of the water, causing a certain degree of damage to natural water resources; Surface water and groundwater are transformed into each other and replaced by bad artificial collateral circulation of infiltration, discharge, re-infiltration and re-discharge; When the mining subsidence spreads to the ground, or when the water-conducting fissure zone in the goaf of an abandoned mine or the scope of ground subsidence expands, the surface water and the pit water will have a direct hydraulic connection an...

[0002] The large-scale mining process is bound to be accompanied by the utilization of a large amount of water resources and the subsequent excretion process. These processes will change the path of the water cycle and the quality of the water, causing a certain degree of damage to natural water resources; Surface water and groundwater are transformed into each other and replaced by bad artificial collateral circulation of infiltration, discharge, re-infiltration and re-discharge; When the mining subsidence spreads to the ground, or when the water-conducting fissure zone in the goaf of an abandoned mine or the scope of ground subsidence expands, the surface water and the pit water will have a direct hydraulic connection and affect each other. discharge, and may infiltrate into the mine again; at the same time, due to a large amount of precipitation infiltrating into the ground, the river runoff is reduced and the water quality is seriously deteriorated, which not only affects the water quality, but also wastes water resources
