NOVELTY - Biogas slurry is supplied to a steel tank filled with quartz sand and having a pump, and the large dregs are filtered. The slurry is pressurized and subjected to reverse osmosis to obtain a slurry concentrate. The water obtained by reverse osmosis is recycled after disinfecting with ozone. The concentrate is recycled, tested and specific components are added. The obtained concentrate is fermented with bacteria to obtain organic fertilizer, and the fertilizer is packed.    USE - Conversion of biogas slurry into organic fertilizer.    ADVANTAGE - Organic fertilizer with excellent quality is produced from the biogas slurry.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for equipment for converting biogas slurry into organic fertilizer, which consists of biogas slurry inlet (1), booster pump (2), sand tank (3), reverse osmosis device (4), concentrated solution outlet (5), ozone generator (6), ozone inlet (7), water tank (8), filler (9) for cultivating water supply device, feeder (10), nutritional solution adding opening (11), concentrated solution collection tank (12), bacterial manure fermentation tank (13) and filler (14). The booster pump (2) is connected with the inlet (1), the inlet (1) is connected with the tank (3), the tank (3) is connected with the reverse osmosis device (4), the concentrated solution outlet (5) is connected with reverse osmosis device (4), the reverse osmosis device (4) is connected with ozone generator (6), the ozone inlet (7) is connected with the ozone generator (6), the ozone generator (6) is connected with the water tank (8), the water tank (8) is connected with the filler (9), the filler (9) is connected with the feeder (10), the feeder (10) and the nutritional solution adding opening (11) are both connected with the tank (12), the tank (12) is connected with the tank (13), and the tank (13) is connected with the filler (14).    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the equipment for converting biogas slurry into organic fertilizer.
