The main components of filter mud and bagasse in sugar factory are broken fiber, fatty matter, protein, mineral and a small amount of sugar, and they contain nitrogen, phosphorus, potassium and other nutrients that can be absorbed by crops. By fermenting these wastes, the organic matter in the filter mud can be further recombined and humified, and then processed into granular products by the organic fertilizer granulator, which can become a new type of bio fertilizer with high efficiency, safety and quality, and realize the secondary utilization of organic wastes.
Technical scheme of sugar residue fermented organic fertilizer
Sugar slag material ratio: 2 parts of filter mud, 1 part of bagasse and 1 part of ash.
1. Dilute the strains, mix 1kg of organic fertilizer inoculum with 10kg of corn flour, and mix it evenly into 5 tons of raw materials.
2. Upset. During the fermentation process, the materials will gradually heat up, and if oxygen is needed, the compost turning machine will be used to process the materials. When the temperature of the compost reaches 50 degrees, turn over the pile in time. When the temperature reaches about 70 ℃, it will fall over twice a day. The entire fermentation cycle is 7-15 days.
3. When the temperature is below 10 ℃, cover the pile with a curtain, straw and other air-permeable insulation; if the pile is covered with plastic film, the film must be removed when the temperature of the compost rises to 40 degrees.
4. After mixing the wet filter mud, the total water content is 40-60%. If the water content is too high, the fermentation time will be extended; if the water content is too low, the fermentation will be incomplete.
Nutrient supplement plan of organic fertilizer
The compost after fermentation of sugar residue conforms to the standard of organic fertilizer, which can effectively kill the pathogenic bacteria contained in the filter mud, degrade toxic and harmful substances, improve the conversion rate of biological enzyme in the filter mud, and decompose the nutrients that are difficult to be absorbed by crops. However, if we want to increase crop yield and help crop growth, we need to supplement other nutrients. The compost is mixed with NPK fertilizer (such as urea, superphosphate, potassium fulvic acid, etc.) and other nutrients, and then it is made into a new type of organic compound fertilizer by disc granulator machine, which greatly improves the fertilizer efficiency.
