FIELD: wastewater purifying.
SUBSTANCE: invention relates to a technology for purifying wastewater from ammonium ions, heavy metals and oil products and can be used in agriculture. The method includes adding natural zeolite with a fraction size of 1.0-1.5 mm to the purified water, stirring, settling in the interval of 12-48 hours, filtering, while BAU-A charcoal with a size of fractions 0.25-0.5 mm in a ratio of 1:1 and uniform mixing is carried out at a rotation speed of 2-3 rpm for 15-20 s.
EFFECT: reduction of the content of ammonium ions, heavy metals and oil products during wastewater treatment below the maximum permissible concentration (MPC) with the possibility of using purified water for irrigation of crops.
