FIELD: water treatment; chemistry.
SUBSTANCE: invention relates to environmental protection and can be used to produce reagents used in water disposal systems for treating industrial multicomponent waste water. Composite reagent for treating multicomponent waste water includes a mixture of powdered components of a coagulant, a flocculant, a sorbent and a pH regulator. Coagulant used is a combined aluminium-silicon coagulant-flocculant. Flocculant used is an anionic flocculant. Bentonite clay is used as sorbent, and calcium carbonate is used as medium pH regulator.
EFFECT: reagent is an inexpensive, easy-to-manufacture, easy-to-store and dispensing powder agent for purifying water from contaminants, when using which there is no excessive mineralization of the effluent of purified water and no secondary wastes are formed.
