FIELD: chemistry.
SUBSTANCE: to implement the method, contaminated waste water is treated with a calcium-containing reagent - precipitation agent in form of defecation mud - wastes from sugar production, where the defecation mud is pre-treated in a heating furnace at temperature t=580-600°C and atmospheric pressure. The degree of purity of waste water from ions of heavy metals is equal to 96-98%, from petroleum products - 98%, from dyes and surfactants - 98.5%.
EFFECT: high efficiency of treating waste water.
