    This invention relates to the treatment of liquids obtained by flushing gases, in particular to methods of treating water containing salts of anthraquinone disulfonic acid, obtained by washing the hydrogen sulphide containing a gas. The known method of purification of hydrogen sulfide-containing gas, including the initial gases of the anthraquinone disulphate salts, is oxidized by oxidation of the liquid obtained at the washing stage, containing salts of the recovered anthraquinone disulphonic acids, and subsequent recirculation of the oxidized liquid, containing the anthraquinone disulpha- culonic acids, and recycling to the oxidant liquids, containing the anthraquinone disulpha acid, and the rest of the day; one . The disadvantage of this method is the formation of deposits in the apparatus, which leads to a periodic stoppage of the process. The closest to the invention in its technical essence and the achieved result is a method of extracting anthraquinone disulfonic acid salts from an aqueous solution containing anthraquinone disulfonic acid salts, sulfates, alkali metal thiosulfates and / or alkali metal vanadium, obtained by washing the hydrogen sulfide with retaining gas, which is enclosed. part of the water is recycled to the flushing of hydrogen sulfide-containing gas, and the remaining part of the water is subjected to incineration — or high-temperature hydrolysis from I. The disadvantage of this method is the low degree of extraction of salts of anthraquinone disulfonic acid due to their decomposition as a result of combustion or high-temperature hydrolysis. The aim of the invention is to increase the degree of extraction of anthraquinone disulfonic acid salts from an aqueous solution containing anthraquinone disulfonic acid salts, sulfates and / or thiosulfates, and / or alkali metal vanadates. The goal is achieved in that according to the method of extracting anthraquinone disulfonic acid salts from an aqueous solution containing anthraquinone disulfonic acid salts, sulfates, thiosulfates and / or alkali metal vanadates, the process is carried out by passing the original aqueous solution through a polypropylene-based macroporous resin based on polymers or polymers. (meth) dacrylate with a pore size of 10-500 A and an inner surface of 100-1000 at 0-80 ° C. According to the proposed method, water containing salts of anthraquinondisulfonic acid is passed through a layer of macroporous resin based on polystyrene or Polymethacrylate having a pore size of 10-500 A and an inner surface of 100-1000 at t 0-80 ° C. The choice of resin with the specified ratio of pores and the inner surface is due to the fact that when carrying out the process using a macroporous resin based on polystyrene and polymethyl methacrylate, having a pore size of 9 I and 510 A, respectively, and an inner surface, 90 1050 MVT, respectively, water obtained during desorption, contains not more than 19.5% of the anthraquinone disulfonic acid salt contained in the starting liquid. The implementation of the process in the temperature range of 0-80 ° C is due to the fact that, at temperatures below and above, the degree of extraction of the salt of anthraquinone disulfonic acid from the solution decreases. . Example. 15 m obtained by washing a hydrogen sulfide gas containing a liquid of the composition, wt%; water 80.0, sodium sulfate 14.7, sodium thiosulfate 2.0, sodium bicarbonate 2.2, sodium carbonate 0.4, sodium salt of anthraquinone disulfonic acid 0.3, vanadate n.tri 0.3, sodium thiocyanate 0.1 and methanol 0,2, is passed through a column filled with 3 m of a macroporous resin based on poly-styrene, having a pore size of 25 A and an inner surface of 300 at t 5 5s and atmospheric pressure. Then, 11.5 m of water with a temperature is passed through the column .. The resulting aqueous solution contains 99.9% of the anthraquinone disulfonic acid sodium salt contained in the initial liquid. Example 2.15m of a liquid of the composition obtained by washing hydrogen sulfide-containing gas, weight,%: water 81.6, sodium sulfate 13.4, sodium thiosulfate, sodium bicarbonate 2.0, sodium carbonate 0.3, sodium tartrate 0.4, sodium anthraquinone disulfonic acid 0.3, sodium vanadate 0.3, is passed through a column filled with 3 m of a macroporous resin based on polymethyl methacrylate, having a pore size of 100 A and an internal surface of 700 m / g, at atmospheric pressure. Then, 11.5 m of an aqueous solution with a temperature of 85 s, containing, wt.%: Sodium sulfate 1.3, sodium bicarbonate 0.4, sodium carbonate 7.3, vanadate nati 0.3 and sodium hydrogen sulfide 2.9 are passed through the column (this solution is obtained by burning the anthraquinone disulfonic acid obtained after adsorption by the sodium salt of one phase with a gas, wt%:
