The invention relates to water treatment plants, in particular to a plant for combined purification of water from hard-degradable organic substances. The plant, according to the invention, includes three cylindrical chambers with different diameter, with a cover (11), interconnected and installed coaxially; the chamber (15) with a large diameter is installed in the upper part, embracing on the outside the upper part of the chamber (10) with a mean diameter, and in the space between these chambers is installed a floating granular charge (16), limited in the upper part by a support grid (17), at the same time the chamber (15) with a large diameter is equipped with a pipe (18) for outlet of the purified water in the upper part and a valve (19) for outlet of the sediment in the lower part; the chamber (10) with a mean diameter is made with conical bottom, inside it is installed a block, consisting of horizontal quartz tubes (13), the edges of which are located outside the chamber (10), and inside the tubes (13) are installed ultraviolet lamps (14); the lower chamber (1) with a small diameter is made of nonmagnetic material, in its lower part is made a water-air bell (6) with a disperser (7), the bell (6) is equipped with air (8) and polluted water (9) delivery pipes, in the upper part of the chamber (1) of a small diameter is installed on a grid (3) a charge (2), consisting of dispersed iron and coke particles taken in the mass ratio of (3à5):1, and outside around the charge (2) is installed a generator (4) of rotating electromagnetic field connected to an alternating current source (5).
