Mining wastewater treatment equipment

The main components of mine water are suspended solids and soluble inorganic matter. Suspended solids (SS) are primarily composed of coal dust and rock dust, and their content is relatively unstable. Furthermore, as mine water flows through coal mining faces and roadways, it is affected by human intervention, introducing some organic matter into the water. The primary SS component in mine water is coal dust, which can be oxidized by strong oxidants like potassium dichromate, resulting in a relatively high CODcr.

Mining Wastewater Treatment Methods

Physical Methods: Separate Sedimentation for Clean and Wastewater

Chemical Methods: 1. Coagulation Sedimentation; 2. Electrodialysis; 3. Reverse Osmosis; 4. Neutralization.

Purification technologies primarily include sedimentation, coagulation-sedimentation, and rapid coagulation-sedimentation (coagulation-precipitation). Different process combinations are employed depending on the intended use.

After treatment, domestic water must be filtered and then disinfected. Some mine water containing suspended solids has a high salinity content and, after treatment, must be desalinated for domestic use.
