Embodiment 1

[0026] The combination of different antibiotic wastewater (erythromycin production wastewater and tetracycline production wastewater) is based on 20m 3 / h into the acidification hydrolysis pool, hydrolysis and acidification for 24 hours (stay). Hydrolysis and acidification effluent according to 20m 3 / h into the digestion tank for anaerobic digestion, the volume of the digestion tank is 60000m 3 About, the anaerobic digestion residence time is 100 days. Anaerobic digestion tank effluent according to 20m 3 / h into the aerobic pool, the volume of the aerobic pool is 5000 m 3 About 10 days for aerobic digestion. The sludge at the end of the aerobic tank is settled and flocculated (organic macromolecule flocculation), dehydrated by filter plate frame, and the antibiotic sludge obtained enters the organic fertilizer fermentation link.

Embodiment 2

[0029] Antibiotic wastewater (erythromycin production wastewater) is matched according to 15m 3 / h into the acidification hydrolysis pool, hydrolysis and acidification for 30 hours (stay). Hydrolysis and acidification effluent according to 15m 3 / h into the anaerobic digestion of the digestion tank, the volume of the digestion tank is 60000m 3 Around, anaerobic digestion for 150 days (stay). Anaerobic digestion tank effluent according to 15m 3 / h into the aerobic pool, the volume of the aerobic pool is 5000m 3 Around, aerobic digestion for 16 days (stay). The sludge at the end of the aerobic tank is settled and flocculated (organic macromolecule flocculation), dehydrated by filter plate frame, and the antibiotic sludge obtained enters the organic fertilizer fermentation link.

Abstract

The invention relates to an organic fertilizer produced from vitamin fermentation waste and a preparation method of the organic fertilizer. The organic fertilizer is prepared by fermenting the following raw materials in percentage by weight: 3-20% of gulonic acid crystallization mother liquor, 10-40% of gulonic acid membrane slurry, 40-80% of antibiotic wastewater sludge and 3-20% of fly ash. Themethod comprises the following steps: performing membrane concentration on gulonic acid crystallization mother liquor and gulonic acid fermentation liquor to obtain the gulonic acid membrane slurry, carrying out hydrolytic acidification, anaerobic digestion and aerobic digestion on antibiotic wastewater, and performing mixed fermentation on the antibiotic wastewater sludge and fly ash to prepare the organic fertilizer. Waste resources can be recycled, economic benefits of enterprises are increased, and meanwhile the problem of industrial pollution caused by fermentation enterprises can be solved.

Description

technical field [0001] The invention belongs to the technical field of biomedicine and waste resource utilization, and in particular relates to an organic fertilizer produced by fermenting vitamin waste and a preparation method thereof. Background technique [0002] At present, the production of antibiotics and vitamins is concentrated in China. Antibiotic fermentation and vitamin fermentation are important industries in my country. While bringing huge economic benefits to our country, they also cause serious problems due to the large amount of waste water and waste residue produced in the fermentation process. Environmental issues. [0003] Vitamin C, also known as ascorbic acid, is usually prepared by biological fermentation, and a large amount of waste is generated during the preparation process: gulong acid crystallization mother liquor and a large amount of waste water. Gulonic acid mother liquor is the residual residue after various steps of centrifugation, ultrafiltra...
