    The invention relates to the field of waste treatment with simultaneous exposure to methane. A device for anaerobic digestion of plants is known; and liquid waste with the formation of methane, containing the body, the pipelines for the supply of waste and the removal of fermented mass and methane, a stirrer (13, the known device provides for the joint cleaning of liquid and solid substrates without separating the components. Such a device does not allow for the repeated use of a solid substrate The considerable dimensions of the device and the need to use the agitator increase its energy intensity, besides, with the continuous process of digestion into the device, New portions of waste are supplied, which lower the temperature of the mixture. For the normal flow of the fermentation reaction, it is necessary to conduct additional heating of the whole mass, which significantly increases the cost of the device.A well-known installation for anaerobic fermentation of solid and liquid wastes with methane formation, containing internal perforated partitions to maintain a solid substrate, providing drainage along the entire height of the tank, and a lower tank for collecting and fermenting the liquid substrate. This plant provides for the fermentation of solid and liquid wastes with associated methane emissions and. removal of the liquid substrate L2. However, in a known installation, there are no supply and discharge units for a solid substrate, which leads to intermittent operation, and the absence of centralized removal of methane from the reaction zone leads to emissions of this gas into the atmosphere. The temperature regime of the known device does not allow for the efficient disposal of waste. The purpose of the invention is the continuous production of methane and an increase in the reliability of the plant. The goal is achieved by the fact that the installation for anaerobic digestion of solid and liquid wastes with the formation of methane, containing a tank equipped with internal. perforated partitions to maintain a solid substrate, providing drainage along the entire height of the tank, and a lower tank for collecting and fermenting a liquid substrate, equipped with a solid substrate loading unit having a screw and a distributor, and a solid substrate unloading unit having one or more screws, pipelines for removal methane and liquid recirculation, connected to a lower container for a liquid substrate, equipped with a pipeline for supplying a liquid substrate and a heat exchanger, and a reserve aru, wherein the tank is equipped with drain pipes ,, ras.polozhennymi over its entire height and connected with a lower capacity. FIG. 1 shows schematically the proposed installation, a general view; in fig. 2 shows a solid substrate supply unit in FIG. 3 - a version of the tank design. The installation includes a tank 1, in the upper part of which a solid substrate feeding unit is placed, including a feeding conveyor 2, a mill 3, an auger 4, located inside the hollow body 5, driven by an engine 6, a distributor 7 made in the form of a saucer. Inside the tank 1, perforated partitions 8 are installed to maintain: a solid substrate; the lower part of the tank is equipped with a solid substrate withdrawal unit including an auger 9 forming a water seal with the tank and gratings 10 regulating the amounts of solid material being discharged. . , The tank 1 is provided with a pipeline 11 for removal of methane by drain pipes 12, located along its entire height and connected to the lower tank 13 for the fermentation of the liquid substrate. In turn, the bottom tank 13 is provided with a coil 14, a pipe 15 for recirculating the secondary substrate connected via pump 16 to the tank 1. The initial liquid substrate is fed to the lower tank through pipe 17, and the fermented material is led to tank 18 by pipe 19. Installation works as follows. The feed conveyor 2 entrains fresh manure and throws it into the mill 3 ,. where the manure is ground
    and is plentifully irrigated with a liquid substrate coming from the lower tank:: 13 through conduit 15. The temperature of the recirculation fluid reaches 40. ° C due to contact with a serpentine 14, through which hot water circulates. The hollow body 5 forms a hydraulic shutter with the distributor 7, whereby the internal cavity of the tank 1 is insulated from the 10 environment. The solid substrate irrigated and thus heated is scattered over the top of the upper part of tank 1. Due to the perforated partitions 8, 5 installed either equidistantly to the walls of the tank, or along the body, divides its cavity into several compartments, the liquid substrate is continuously separated from the solid with simultaneous methane output. The liquid thus filtered is drained through the drain pipes 12 into the lower tank 13 to ferment the liquid substrate. There, he mixes 25 seconds with the initial liquid substrate, for example, with slurry coming through pipeline 17, completed
    in sight, siphon. Pump 16 for recycling heated and fermented liquid JQ
    : ensures its return for the purpose of irrigating fresh solid substrate entering the tank.
    When connected to an overflow pipe 12, an overflow pipe (not shown) connected to the waste liquid return line 19 and the recirculation of the hot squeezed liquid stops the tank 1 is completely filled and the waste liquid is forced out into the pipe 19 and is discharged into the container 18. Fermented solid the substrate is withdrawn from the base of tank 1 by means of a selection device formed by a set of grids 10 and a screw 9. Pipeline 11 removes light methane from tank 1 and lower tank 13 and directs it to the air conditioner vanie and further use.
    The proposed installation allows the fermentation process to be carried out continuously and with minimal energy costs, to separate the mixture into a liquid and solid substrate, which is easily transported and can be used as a fertilizer, and remove methane for its further use. . cpi / e.i z / x / x / xxky ///
