FIELD: water treatment.
SUBSTANCE: invention relates to methods of purifying waste water from oil products and other types of contaminants and can be used for treating waste water using a chemical-free method. Method involves mechanical and sorption purification by filtration through a sorbent layer. Sorbent represents modified pine sawdust with particle size of 1 to 3 mm in air-dry state, treated together with treated waste water by microwave electromagnetic radiation. Radiation frequency is 2,450 MHz at power 140-300 W, treatment is carried out until temperature of the mixture is from plus 32 °C to plus 50 °C.
EFFECT: high efficiency and possibility of recycling wastes.
