1. Sterilizer liquid comprising a liquid supply channel having a permeable wall UV radiation, providing a surface area for exposure, and a cross section of the channel is from 1 × 5 × 10mdo 10m, and thickness of the channel defines a depth of the fluid flow adjacent to the UV-transmitting radiation wall, no more than 50 mm UV light source provided for fluid exposure flowing in a flow channel through transmissive UV wall so that the UV radiation incident on the fluid in the channel, has a density of ultraviolet radiation energy, a plurality of stages mixing configured to provide a turbulent flow in the fluid and spaced along the length of the channel, the channel segments between the mixing stages are arranged so as to ensure the flow adjacent to the transmissive UV wall flow control means provided for controlling the linear rate of fluid flow along channel based on the channel length and the density of UV radiation energy, so that at least 300 Joules of UV energy per square meter of radiation surface is provided for the liquid residence time in the fluid kanale.2. Sterilizer according to claim liquid. 1, characterized in that the mixing step comprise UV transmissive material.3. Sterilizer according to claim fluids. 2, characterized in that the mixing stage are arranged so that UV light from the UV radiation source can reach the internal surfaces of the mixing stage, the mixing stage when filled UV radiation transmitting zhidkostyu.4. Sterilizer according to claim liquid. 1, those wherein1. Стерилизатор жидкости, содержащий:канал подачи жидкости, имеющий пропускающую УФ-излучение стенку, обеспечивающую площадь поверхности для облучения, причем поперечное сечение канала составляет от 1×10мдо 5×10м, и толщина канала определяет глубину потока жидкости, прилегающего к пропускающей УФ-излучение стенке, не более 50 ммисточник УФ-излучения, предусмотренный для облучения жидкости, текущей в канале, через пропускающую УФ-излучение стенку так, что УФ-излучение, падающее на жид
