This technical model aims to produce granular organic fertilizer by integrating livestock and poultry manure (processed via centrifugal dewatering), spent mushroom substrate, and crop straw. This approach facilitates an ecological cycle characterized by zero waste and zero pollution throughout the agricultural production chain. Furthermore, the inclusion of anaerobic fermentation tanks and oxidation ponds allows for the treatment and basic disinfection of wastewater, which is then repurposed for washing down the facility. This strategy not only reduces the costs associated with meeting discharge standards but also lessens the overall wastewater treatment load.
