Embodiment 1

[0037] Mix the erythromycin fermentation residue with the No. 1 solidification dehydrating agent (the main component is sodium carbonate) at a mass ratio of 1:0.2, and carry out a solidification reaction at 0°C under stirring conditions to obtain a dry solid mixture of the residue.

[0038] Morphology of erythromycin fermentation slag before and after solidification and dehydration figure 1 It can be seen from the figure that after the solidification reaction of the bacteria residue, the physical appearance has changed from a colloidal state (a) to a dry solid powder (b).

Embodiment 2

[0040] Mix penicillin fermented bacteria residue with No. 2 solidified dehydrating agent (mainly composed of magnesium sulfate) at a mass ratio of 1:3, and carry out solidification reaction at 100°C under stirring conditions to obtain a dry solid mixture of bacteria residue.

[0041] The morphology of the penicillin fermentation slag before and after solidification and dehydration figure 2 It can be seen from the figure that after the solidification reaction of the bacteria residue, the physical appearance has changed from a colloidal state (a) to a dry solid powder (b).

Embodiment 3

[0043] Mix griseofulvin fermentation residue with No. 3 solidification dehydrating agent (the main component is copper sulfate) at a mass ratio of 1:1, and perform a solidification reaction at 15°C under stirring conditions to obtain a dry solid mixture of residue.

[0044] Morphology of griseofulvin fermentation slag before and after solidification and dehydration image 3 It can be seen from the figure that after the solidification reaction of the bacteria residue, the physical appearance has changed from a colloidal state (a) to a dry solid powder (b).

Abstract

The invention provides an antibiotic zymocyte dreg curing dehydrating method. The method comprises the steps that antibiotic zymocyte dregs and a curing dehydrating agent are mixed for a curing reaction, and moisture in the antibiotic zymocyte dregs is removed; and the curing dehydrating agent is any or a combination of at least two inorganic substances and/or organic substances which can form hydrates, absorb moisture or react with water. Zymocyte dreg solid mixtures generated through the curing reaction can be subjected to resource utilization or incineration disposal directly or after dehydration. Through the method, the rapid dehydrating temperature and complete dehydrating temperature of the zymocyte dregs can be lowered by 10-90%, the problems that antibiotic zymocyte dregs are difficult to store and transport at the room temperature, prone to secondary fermentation and pollution and high in cost in treatment processes such as dehydration are solved, and a new method is provided for low-cost resource utilization and harmless treatment of the antibiotic wet zymocyte dregs.

Description

technical field [0001] The invention belongs to the technical field of antibiotic fermentation slag treatment and waste resource utilization, and relates to a method for solidifying and dehydrating antibiotic fermentation slag, in particular to a method for treating antibiotic fermentation wet slag to realize low-cost solidification of antibiotic fermentation slag Dehydration and its resource utilization and harmless treatment methods. Background technique [0002] my country is the world's largest producer of antibiotics, and 90% of global antibiotic raw materials are provided by my country. The production process of antibiotic raw materials includes fermentation, extraction, refining and other unit processes. During the fermentation process, a large amount of antibiotic fermentation residues are produced. In my country, about 2 million tons of antibiotic fermentation residues need to be treated urgently every year. Antibiotic fermentation residue is mainly composed of fe...
