FIELD: chemistry.
SUBSTANCE: invention can be used in the chemical industry and water treatment. Sorption water purification from ammonium nitrogen of fish farming enterprises is carried out at sorbent supply, mixing and separation of the solid phase. Chemically or thermally activated rice straw is used as a sorbent. When the rice straw is chemically activated, it is washed in the distillate, and upon thermal activation, freezing or high-temperature carbonization is carried out in an electric furnace or by concentrated sunlight.
EFFECT: method for sorption purification of water from ammonium nitrogen is proposed.
