In the process of mining, with the increasing depth of mine excavation, the contact reaction between underground water and coal and rock strata causes the color of underground water to become turbid, and it contains a large number of suspended matter and harmful elements. These underground mine waste water cannot be directly drunk, otherwise, it will be toxic. The mining waste water must be treated and process
Experts in Brother filtration take a long-term and overall perspective towards the treatment of mine sewage. The best mining filtration solution is to obtain long-term benefits, to establish environmental awareness and scientific management awareness, which is conducive to the long-term development of our customers.
Different types of mine water have different water quality, and we should adopt different water treatment schemes.
1. Collect waste water and put it into the catchment regulation pool, and constantly regulate the amount of water;
2. Let the waste evenly mixed with the flocculant, settlement and separation quickly; the sludge removal process is completed by gravity in the sedimentation sludge tank;
3. The pre-filtration water is stored centrally after filtration and disinfection and the sludge is made into mud cakes for agricultural or pour into the Marine.
Most back wash process of filter pool is controlled by automatic equipment, but for treatment of mining water, we can’t judge the water flow rate, water quality, both of them are unstable. To solve the impact of instability of mine water. We could adopt a manual value on the outlet pipe of the filter to control water volume. Sedimentation, clarification and filtration, we will meet various problems due to the influence of various factors in the actual production operation, but we must specifically analysis combined with the objective situation to find out the solution measures.
After pre filtration, most of the sediment in the mining waste water is removed. To meet the quality requirements of Municipal water, we should to do further filtration. Mineral sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical, catering and other fields, and it is step by step move into the daily life of people.
To remove suspended solids in sewage, we usually use an activated carbon filter elements; the BOD removal rate of the waste water after primary treatment is only 20%, so it is still not suitable for discharge.
To remove most colloidal and dissolved organic matter in sewage, we usually use a precise filter with membrane filter element; the BOD removal rate of the waste water after secondary treatment is about 80%～90%, it is allowed to be discharged.
Further removal of certain specific pollutants, such as fluoride and phosphorus removal, we need to add the chemical addition, and do deeper filtration by RO system.
