Problems solved by technology
The annual output of filter mud is tens of millions of tons, which is difficult to handle, accumulates and occupies an area, wasting huge land resources
Sugar production is to use raw sugar to process and purify to produce white granulated sugar, etc. The moisture and organic nutrients of carbonation filter mud cannot meet the standards of biological fertilizers, which brings great difficulties to a large amount of filter mud consumption. At present, there is no relatively perfect method at home and abroad. Method for processing and utilizing the filter mud

Embodiment
[0018] Use corn soaking liquid as raw material, concentrate the corn soaking liquid puree twice, add filter mud and lye to neutralize, adjust the pH value to 5~6, put it into the mixing pre-fermentation device, add crushed powder to the fermentation device Good protein cake, filter mud and fiber residue, so that the solid content is controlled at 5-10%, fully mixed and then pre-fermented; then use an anaerobic fermentation device, add 1‰ active dry yeast biological strains, and again at 30°C Fermentation; the fermented product is dried, granulated, cooled, and sieved after adding ingredients to obtain the product; the biogas generated during the fermentation process of the anaerobic fermentation device is collected and then enters the connected fermentation device through a water-sealed tank and a flame arrester , a biogas boiler of a drying device and a granulation device; the ingredients are one or more of crushed rice straw, straw, plant ash and fiber slag; the lye is potass...

The invention relates to the field of agricultural and sideline product deep processing and particularly discloses a method for preparing biological fertilizers from corn soaking liquid. The method uses the corn soaking liquid as raw materials and is characterized in that the corn soaking liquid is concentrated, then, filter mud and alkali liquor are added for neutralization, the pH is regulated to 5 to 6, the corn soaking liquid is thrown into a mixed pre-fermentation device, crushed protein cake, filter mud and fiber slag are added into the fermentation device, and the pre-fermentation is carried out after the full mixing; then, an anaerobic fermentation device is adopted, biological species are added, and the fermentation is carried out again at 28 to 30 DEG C; and fermented products are added with ingredients, then, the drying, the granulation, the cooling and the screening are carried out, and then, products are obtained. The method has the advantages the environment pollution and the environment protection pressure are lightened, the corn soaking liquid and the filter mud of sugar refineries are effectively treated, new products are also developed, the nutrition and irrigation requirements of local farmers are met, and the effect of getting two results from one effort is reached.
Description
(1) Technical field [0001] The invention relates to the field of deep processing of agricultural and sideline products, in particular to a method for making biological fertilizer by using corn soaking liquid. (2) Background technology [0002] At present, agricultural production generally depends on chemical fertilizers. On the one hand, it will cause environmental pollution. In fact, the non-point source pollution in rural areas is already quite serious, which has become a thorny problem. On the other hand, it will also affect the quality of agricultural products. While using the cost, we must increase the proportion of organic fertilizers. The use of biological fertilizers can not only increase production, but also improve quality, protect the ecological environment, and can widely use urban and rural organic waste. In the past ten years, many scientific research units and relevant departments have cooperated in the development and development of various organic waste ...
