FIELD: chemistry.
SUBSTANCE: method of purifying waste water includes adding a natural zeolite to the water to be treated, mixing, settling and filtering. The natural zeolite used is a natural zeolite containing 50-60% clinoptilolite with particle size of 1.0-1.5 mm. Uniform mixing is carried out at a rate of 1-2 rps for 10-15 s and settling is carried out for 12-48 hours.
EFFECT: low content of heavy metal and ammonium ions when treating waste water below the maximum allowable concentration while enabling use of the treated water for crop irrigation.
