MAKING OF ARTIFICIAL GEOCHEMICAL MECHANICAL BARRIERS FOR PURIFICATION OF WASTE WATER OF PLACER DEPOSITS
Considerable injury to environment can be caused by waste water with a great number of suspended particles. For clearing of them ground filters stacked in a channel of the river are used on the diamond deposits in the Perm Region. As a material for filters dredged ground wastes located in the Vishera river valley were used. Full-scale experiments have shown that depending on a path length of filtration the concentration of suspended particles in waste water can be reduced by tens or hundreds of times. Based on the conducted activities, the writers have computed optimal parameters for ground filters. The maximum initial concentration of suspended load, grain composition of used grounds, discharge of the river and work time of filters are taken into account. The applying of ground filters does not require high costs and is capable to reduce the content of suspended particles up to values close to background concentration
