FIELD: chemistry.
SUBSTANCE: invention relates to waste water treatment techniques. The method involves treating water with sodium phosphate in the presence of fibrillated cellulose fibres in amount of 100 pts.wt per 100-900 pts.wt of the formed aluminium phosphate. Water can be pre-treated with sodium hydroxide solution in the presence of said fibres. The treatment product is separated by pressure flotation.
EFFECT: invention provides high treatment efficiency.
