| Summary: | The article provides the results of research on the development of non-wood manure and plant biomass processing technology for the production of biogas and environmentally friendly fertilizer (fermented humus) in the conditions of an agricultural enterprise in Poland. The slurry from the manure channel enters the preliminary storage unit of the substrate, where it is mixed and then transported to the fermentation chamber. Fermentation chamber is filled once a day with daily output of manure. Vegetable biomass is fed to the fermentation chamber in two portions, which provides three-fold mixing of the contents during the day with a hydraulic unit. The substrate subjected to methane fermentation is periodically stirred with a spatula mixer, which allows to accelerate the biogas process. The sulfur removal process is based on the passage of gas through charcoal, placed on the shelves of the cleaner. Gas meter allows you to control its production. Gas from the collector is sent to the water boiler, the work of which is automated. Warm water for heating the fermentation mass comes from the boiler through pipes into the fermentation chamber. Its task is to increase the temperature of compost up to 36°C and maintaining it during the fermentation process. Stability of humus temperature in the chamber is provided by the temperature controller (thermostat). Fermented compost undergoes further processing, which consists in mixing it with chopped straw, peat and other plant wastes. The mass is sent to an open humus chamber, where it is kept for about 3 months and is supplemented with fresh humus throughout the period. Biogas unit allows to recycle wastes in the areas of production and processing of agricultural products, to improve the environmental situation, to obtain biogas and environmentally friendly fermented humus with various plant additives, which belong to the group of very active biological fertilizers that stimulate the growth and development of cultivated plants. |
