According to known methods, deep aeration of sewage is achieved by passing through the layer of stationary sewage, released near the bottom of the tank, with air bubbles. Known devices for deep aeration include high-efficiency fans with high spring, compressed air distribution ducts, and aeration elements located at or near the bottom of the tank, usually in the form of perforated box grates. They are mixed into the nozzle packages and mixed with air, given the right direction and speed, and released near the bottom of the tank. The device according to the invention has a water pump and associated with it by means of pipes, packages of nozzles connected with the pipes. The inlet air slots are located around the free outlet ends of the nozzles. The collectors are preferably in the form of a hollow cylinder, and the nozzles in the cross section have the form of equilateral triangles. The advantageous effect of the invention is a significant reduction in the cost of wastewater treatment and making it possible to operate the sewage treatment plant in all weather conditions. 1 shows a schematic drawing of the device in an axial section, Fig. 2 an axial section of the collector and Fig. 3 a cross-section of a collector. As shown in the drawing, the device comprises a water pump 1 immersed in the sewage to be treated at a small depth. The water pump 1 is connected by means of pipes 2 with packages of nozzles 3 located in collectors 4. Collectors 4 are connected with pipes supplying air 5, and on the front side they are equipped with ejectors 6. The nozzles 3 are fixed on one side to the rear wall 7 collectors 4. Free ends 8 of nozzles 3 located in the openings of the front walls 9 of the collectors 4, and the openings of the front walls 9 are selected so that inlet air slits 10 are formed around the free ends 8 of each 3. The collectors 4 are preferably in the form of a hollow cylinder. The cross-section of the nozzles 3 is preferably also in the form of equilateral triangles. During the operation of the device, the water pump 1 takes the raw sewage near the surface of the tank of the treatment plant and forces it through pipes 2 into the nozzles 3 of the collectors 4 * Sewage flowing into the nozzles 3 creates a vacuum in the collector 4, they suck in the air which flows through the slots 10 and mixes with the effluents in the launcher 6. The dimensions of the launchers 6 are so selected that the mixture flowing out at their outlet obtains the proper outflow velocity and the mixture is calm. The wastewater flowing out of the launcher 6 causes the movement of wastewater and sludge throughout the treatment plant, and the air bubbles flowing through the wastewater layer cause their required oxidation. Pump 1 can be connected to a number of sets of nozzles 3 depending on the capacity of pump 1. In order to increase the aeration efficiency, air can be blown into the collector 4 with a fan with a low efficiency and low pressure. The method and device for deep aeration can also be used for not in the case of aeration of breeding water reservoirs. Patent claims 1. The method of deep aeration of sewage, characterized by the fact that the aerated sewage is collected near the surface of the reservoir and then it is introduced into the nozzle packages and mixed with air, it gives the appropriate direction and the appropriate speed and released near the bottom of the reservoir. 2.
