Embodiment Construction

[0012] A method for treating waste water during mining, comprising the following steps:

[0013] The first step: study and utilize the favorable terrain in the mine, select a suitable large-capacity goaf as a natural filter pond and sedimentation pond, and treat the mine wastewater so that the mine wastewater can be recycled underground;

[0014] Step 2: According to the analysis of the water quality characteristics of mine water, if the heavy metals and other harmful and difficult-to-remove pollutants do not exceed the standard, simple purification and utilization of mine water can be carried out to remove suspended solids and bacteria in mine water, and neutralize acid mine water. and, can meet the mine operation water requirements;

[0015] The third step: clearing and diverting the sewage, building a concentration pool in the mining area, using mechanical equipment to realize the separation of clean and sewage through dosing and mechanical stirring, reuse of supernatant wa...

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...
