Problems solved by technology

2. Mine wastewater
[0006] 2. Harm to agricultural production
[0007] 3. Corrosion mining equipment
Acidic mine wastewater can severely corrode pipes, ventilation and drainage equipment; concrete or wooden structures that have been corroded by acidic water for a long time will have their strength and stability greatly reduced
[0008] 4. Pollution of ground water
[0009] 5. Harm to human health
[0010] At present, with the increase of mine development depth and the increase of surface water seepage, etc., the mine water cannot be completely reused in the production process, and part of the water can only be drained out.
Mine gushing water contains heavy metals such as As and Sb, and it is required to meet the Class II standard of the "Environmental Quality Standard for Surface Water" (GB3838-2002) after treatment and antimony to reach the limit of 0.005 for centralized drinking water sources. However, there is no such treatment method in China at present.

Embodiment 1

[0033] A gold-antimony mine treatment method for underground water gushing up to standard discharge, the steps include: using an electrochemical method and HSJ antimony agent to treat heavy metal substances in the mine gushing water; the heavy metal substances include As and Sb.

Embodiment 2

[0035] A method for gold-antimony mines to treat underground water gushing up to standard discharge, the steps of which are as follows:

[0036] (1) Mine wastewater enters the adjustment tank for adjustment and storage, pumps the adjustment tank water to the pH adjustment tank, adds lime milk or / and bleaching powder to adjust the pH to 9.0-9.5, adds flocculant for flocculation, and then enters advection sedimentation The pool is clarified to obtain clear liquid;

[0037] (2) The supernatant liquid enters the electrochemical reaction equipment, and the effluent from the electrochemical reaction equipment enters the aeration tank for aeration. At the same time, the antimony agent is added to control the pH to 5.0-5.5; the wastewater from the aeration tank is pumped into the No. 1 flocculation tank, and after flocculation After the agent is flocculated, it enters the No. 1 thickener;

[0038] (3) The effluent from No. 1 thickener enters the pH adjustment tank, and the pH is adju...

Abstract

The invention discloses a method for achieving up-to-standard drainage by treating gushing water under a gold antimony mine well. An electrochemical method and an HSJ antimony-removal preparation areadopted to treat heavy metal matter in the gushing water of the mine well; and the heavy metal matter comprise As and Sb. The method can lower the cost, is easy to operate and environmentally friendly, and can achieve up-to-standard drainage of waste water by being utilized for treating the gushing water under the gold antimony mine well.

Description

technical field [0001] The invention relates to a method for discharging underground water gushing up to a standard, in particular to a method for treating underground water gushing up to a standard in a gold-antimony mine. Background technique [0002] Mine water pollution refers to the phenomenon that mining industrial wastewater and domestic sewage containing various pollutants and toxic substances change its normal composition after being discharged into the water body, exceeding the self-purification ability of the water, thereby deteriorating the water body and destroying the original use of the water body. [0003] Many production processes in mine production require water, among which mining and beneficiation use the most water. The mining and beneficiation process will cause serious water pollution and form mine wastewater. The main sources of mine wastewater are as follows. 1. Open pit mine wastewater. Waste water formed by mining production process; acidic water...
