Technogenic Load on Water Resources of the Coal-mining Regions


The state of Kuzbass water resources is attracting more and more attention, which is associated with increasing industrial use. The risk of reducing the sanitary reliability of water bodies is due to an increase in the amount of industrial wastewater and the multicomponent nature of their composition. For Kuzbass as a coal-mining region, wastewater treatment of coal mining and processing enterprises is relevant. The data of monitoring reporting, the characteristics of the applied cleaning methods are given in the paper.

The most common system of treatment facilities in coal mines, the formation of runoff and problem areas are considered. The sewage receiver is small rivers, the layers are drained by natural drainage, the drainage water is collected in sumps, then it is pumped to the settling ponds by pumps. In the settling ponds, wastewater stays for several days, which leads to the release of suspended particles. After the dam, the treated wastewater is divided into two streams: one is discharged into a reservoir, the other is sent to a storage pond to use this water in the technological process. The possibility of using filtration through artificial filter arrays with a layer consisting of a carbon sorbent at the second stage of purification was studied. The filtering carbon material based on anthracite — Purolat-Standard and coconut charcoal, the raw material for which is a natural material, are analyzed. Adsorption isotherms were used as a criterion for evaluating the adsorption capacity of materials. The sorption capacity of coconut charcoal with respect to iron ions when extracted from individual model solutions, according to the experiment, was 0.54 mg/g. The content of manganese in the solution after adsorption on coconut charcoal decreased according to the experimental data, and the adsorption value was 147 mg/g.
