FIELD: environment control methods. SUBSTANCE: method relates to liquidation of consequences resulted from pollution of ground surface with oil and petroleum products. According to method, initially determined is location of swampy ground site which is polluted with oil. Decision is taken for cleaning polluted site by installing water-impermeable frame which is sunken, and after that enclosed space is filled with water. Impurities are removed by mechanical operation. This operation is performed simultaneously with filling enclosed space with water immediately after floating-up of impurities to water surface. Impurities are removed by device intended for collecting petroleum products. Water for filling enclosed space is supplied under higher pressure after heating it to temperature of 30-40 C. Aforesaid method is technologically simple and sufficiently effective. EFFECT: higher efficiency. 2 cl, 1 ex
