SUMMARY
On the basis of the angrensky coal are received new adsorbents: composite, with the additive in coal of carbonic salts of shchelochno-ground metals for sewage treatment from ions of inorganic impurity and decrease in rigidity of artesian waters; coal heat treatment at 5500?, with waterproof properties (S=150 m2/g) for clearing of a surface of sewage of mineral oil; steam-gas activation at 8000? (S=700 m2/g) for sewage treatment from the dissolved organic impurity; oxidation by air at 180-2000?, preliminary thermo processed coal at 5500?, with high ion-exchange selectivity (capacity 1,8 mg.ekv./g).
