Embodiment Construction
[0009] see figure 1 , mix alcohol waste mash with sugarcane pith, then add filter mud, coal ash and compound strains composed of yeast, bacteria, and actinomycetes to mix together. The mixing ratio of each component is 35% to 45% of sugarcane pith %, 35% to 40% of filter mud, 15% to 25% of coal ash, 3‰ to 8‰ of composite bacteria, and the balance is alcohol waste mash. The amount of alcohol waste mash is added to keep the material moisture from 65% to 70% is better, and the temperature when the alcohol waste mash is added is below 40°C, and then stacked and fermented, the temperature during fermentation is 55°C to 65°C, and the fermentation time is 15 days to 20 days. The filter mud for the above-mentioned preparation of solid fertilizer adopts the sugar factory sub-method filter mud, air-dried to less than 50% moisture, coal ash air-dried to less than 40% moisture, when fermenting, the material should be turned over every 3 to 4 days, so that The temperature of each part of ...
