FIELD: chemistry.
SUBSTANCE: device for purification of surface sewage waters includes filter or settling chamber 1, intended for preliminary purification from coarse dispersed pollutants, purification unit 2, which contains filtering charge 4 with vegetation 5. As filtering charge 4 used is mixture of soil with zeolite, with zeolite amount constituting 30-50% of the total charge weight. Reservoir 6 with bulk hollow deformation-resistant charge 7 for accumulation of purified sewage waters in form of gravel or crushed granite with hollowness up to 50% is placed under filtering charge 4.
EFFECT: invention makes it possible to realise all-year-round purification of surface sewage waters, accumulate and use purified water under cold climate conditions.
