Useful model relates to the field of biotechnology and ecology, in other words to devices of microbiological neutralisation of (reactor closed isothermal type), and is directed for restoring land, contaminated by oil products. The essence of the : installation for microbiological purification of oil-contaminated soils includes receiving bin 1 for loading, storing, primary heating and uniform spreading contaminated soil, ; walls of receiving hopper are inclined not less than 60 °, cultivators 2 for grinding, aeration and mixing soil, bioreactor 3, guide beam 4, two tank-accumulator for biopreparation with fertilizers 5 and water 6, system of irrigation equipment, containing pump 7, hoses 8 and watering cans 9 for treatment of soil reagents and watering water, blower-heater 10 for heating air, worm motor-reduction gear 11 for drive of bogie with located on it cultivators 2 motor-reduction gear (on figs. not shown) for drive discharge screw, auger for unloading (on figs. not shown) the purified soil, shield power supply and control 12, at that installation additionally contains teploizolirovannoe base with heated hollow 13 and all units of plant are arranged in sealed volume with transparent roof 14, made from polycarbonate material for provide operation in cold time of year. Additionally at operation in conditions of insufficient solar light under crown is installed Mercury-vapor lamps extended spectrum 15 and unloading purified soil from bioreactor is carried out on 70-75%. Technical result of the utility model is to diffusion lu in 2-3 times of installation efficiency, quality of cleaning of soil, possibility of treating contaminated soils at lower possible in the freely chosen temperatures and retention of microflora, adapted to this type of petroleum products. 2 3. u. 2 cl; 1 dwg.
