Information

The water quality components of mine wastewater are mainly suspended matter and soluble inorganic matter.Suspension SS is mainly composed of pulverized coal and rock powder, and its content is relatively unstable.In addition, when the mine waste water flows through the coal face and roadway, it will be affected by human activities.Some organic matter mixed into the water.The main component of SS in mine wastewater is pulverized coal, which can be oxidized by strong oxidants such as potassium dichromate.Therefore, it shows a high CODCr.

 

 

To sum up, the main pollutants of coal mine water and coal preparation wastewater are:

(1) Toxic pollutants include: mercury, lead, chromium and other heavy metals;Inorganic poisons, such as fluoride, and some organic poisons.

(2) Radioactive pollutants include: natural uranium, radium and Ra series of nuclides.

(3) Inorganic pollutants include: inorganic acid, salt and inorganic suspended matter.

Physical method: clean sewage and sedimentation

Chemical methods: 1. Coagulation sedimentation method 2. Electrodialysis method 3. Reverse osmosis method 4. Neutralizational process

Purification treatment technology mainly includes precipitation, condensation precipitation, condensation precipitation filtration (condensation clarification filtration), etc. After treatment, different process combinations are adopted according to different uses.

After treatment, it can be used as domestic water and must be disinfected after filtration.Some mine wastewater containing suspended solids is so salty that it must be purified before being desalinated as drinking water.
