System for biochemical reprocessing of livestock organic waste

The invention relates to a system for reprocessing of livestock organic waste and can be used for obtaining biogas, fertilizers and service water.The system, according to the invention, includes a hydraulic flushing block, including an organic waste flushing device (1), connected to a service water supply system, a capacity (3) for the collection of organic waste, connected to another water supply system, with a submersible pump (5) and a level sensor located in the capacity (3), connected to a control unit, after which the waste is fed into a unit for separation of organic waste into solid and liquid fractions, including a distribution capacity (6) with liquid drainage branch pipes, connected to vertical settlers (7) with solid (9) and liquid (8) fractions drainage branch pipes, equipped with valves (10), in the settlers are placed a submersible pump (11) and a level sensor (13), the submersible pump (11) of the settler (7) being connected to a water-air pump (12). The liquid fraction is fed into an aerobic treatment unit, comprising an anoxic reactor (15) with a submersible pump (16), a level sensor and two water-air pumps (17, 18), first (19) and second (20) stage biotanks, a secondary settler (21) equipped with a branch pipe (22) for discharge of circulating activated sludge, connected through a valve to the anoxic reactor (15) and a branch pipe (23) for discharge of excess sludge, the biotanks (19, 20) are equipped with water-air pumps (24), and the second stage (20) biotank is connected to the settler (7) through a branch pipe (25). From the secondary settler (21) the liquid enters the post-treatment unit (27), including capacities equipped with drainage and wells (28) connected in series therewith, each well is equipped with a water level control (29), and in the last well is additionally located a dispenser (30) of disinfecting solution and a pump (31), said well is connected to a hydraulic flushing device (1) for the recycling of service water and is equipped with a branch pipe (32) for discharge of treated water. The solid fraction from the settler (7) enters the unit for processing of solid fraction into biogas and fertilizers, which includes a sediment metering capacity (34), equipped with a submersible pump (35) and a level sensor, at the same time the sediment metering capacity (34) is connected to the first (36), second (37) and third (38) stage methane tanks and the secondary settler (21) of the aerobic treatment unit. The methane tanks (36
