FIELD: power industry; chemical and other industries.
SUBSTANCE: the invention is dealt with reactant methods of purification of natural and industrial wastewater and may be used in power and chemical industries, and also in other industries, where there are installations of chemical water preparationu and an purification of waste water. The offered method of purification includes a water treatment with coagulants - compounds of aluminum and flocculant-polyacrylamide, and also with arrester. At that in the capacity of the arrester is used a waste of production of nitrogenous phosphatic fertilizers containing 90-95 % of calcium and a magnesium carbonates. The method ensures an increase of productivity of the installations and an increase of purified water production.
EFFECT: the invention ensures increased productivity of the installations and an increase of purified water production.
