Example Embodiment

[0022] Example 1

[0023] Such as figure 1 As shown, a method for preparing organic fertilizer from cephalosporin residue includes the following steps:

[0024] In the first step, the cephalosporin residue is pretreated. First, the fresh cephalosporin residue is freeze-dried in a cold air environment with an airflow velocity of 3.5m / s at -10°C, and the fresh cephalosporin residue is frozen into Then crush the frozen cephalosporin residue into solid particles with a particle size of 5-20 mm, and then pass the cephalosporin residue solid particles into a heating furnace with an oxygen content of 0 for 5 minutes The cephalosporin residue solid is heated to 800°C and kept for 30 minutes, and then naturally cooled to 40°C with the furnace to obtain the pretreated cephalosporin residue and kept warm for later use;

[0025] The second step is to configure the fertilizer matrix. First, the selected volcanic rock material, pyrite slag, activated carbon particles, rare earth, calcium sulfate...

Abstract

The invention discloses a method for preparing an organic fertilizer from cephalosporin fungus residues. The method comprises four steps: pretreating the cephalosporin fungus residues; preparing a fertilizer substrate; carrying out fermenting operation; and granulating. Compared with a traditional treatment process of the cephalosporin fungus residues and a processing technology of the organic fertilizer, the method disclosed by the invention has the advantages that raw materials are convenient to obtain, low in cost and small in toxic or side effects; a processing and producing technology issimple; while the resource recycling rate of materials such as crop straws, pond sludge, biogas residues and the like is effectively improved, on the one hand, the harmless disposal and resource recycling rate of the cephalosporin fungus residues are effectively improved, and the cost of treatment operation of the cephalosporin fungus residues and the working efficiency are reduced; on the other hand, the exerting efficiency of fertilizer effect is effectively improved; the aims of effectively reducing the fertilizing amount and reducing the intensity of the fertilizing operation and the costare achieved while the fertilizing effect is met.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method for preparing organic fertilizer from cephalosporin residue. Background technique [0002] In the harmless treatment and recycling of cephalosporin residues, it is one of the important means to improve the fertilizer efficiency of organic fertilizers to make cephalosporin residues participate in the organic fertilizer preparation process. In the process of organic fertilizer preparation, in order to reduce the toxicity and pollution of cephalosporin residues, it is often necessary to use traditional incineration, fermentation and other processes for harmless treatment of cephalosporin residues, and then participate in organic fertilizers. During the preparation, although it can meet the needs of actual production operations, when the traditional incineration process harmlessly treats cephalosporin residues, due to the high water content of fresh cep...
