Abstract
Dirty wastewater from coal mining and processing enterprises requires treatment even to be used as process water and to be discharged into natural water bodies. One of the common treatment methods is water settling in special tailings ponds, which continuously receive contaminated water and from where the already treated water is pumped out to maintain the water level in the pond. This paper examines various configurations of the water injection system into the tailings ponds in order to study the flow patterns and their effect on the treatment result. It is found that the optimal location of the inlet pipes is near the surface of the pond. Complex vortex-type flows are formed in the ponds, and the configuration of the inlet pipes affects only a small extent of the tailings pond length.
