Antibiotic mushroom dreg microbial fertilizer and preparation method thereof

Abstract

The invention discloses an antibiotic mushroom dreg microbial fertilizer and a preparation method thereof, belonging to the technical field of microbial fertilizers. The antibiotic mushroom dreg microbial fertilizer disclosed by the invention is composed of antibiotic mushroom dregs, a microbial agent, an organic fertilizer and an inorganic fertilizer, wherein the antibiotic mushroom dregs are oneselected from tetracyclic antibiotic mushroom dregs, polypeptide mushroom dregs and glucosamine mushroom dregs, and the effective viable count of the microbial agent is not less than 5.8 * 10<8> / g. According to the method, antibiotics in the antibiotic mushroom dregs are removed; carbide slag is used for preparing the inorganic fertilizer; the antibiotic mushroom dreg microbial fertilizer is granulated, time consumption is short, and the activity of the antibiotic mushroom dreg microbial fertilizer is maintained; the method has characteristics of simple process, usage of easily available rawmaterials, efficient and safe removal of residual antibiotics in the bacterial residues and effective utilization of the antibiotic mushroom dregs in the microbial fertilizer; and the antibiotic mushroom dreg microbial fertilizer is simple in preparation method, low in cost, low in application amount, good in crop yield increasing effect, and capability of realizing resource recycling and ecological environment protection.

Description

technical field [0001] The invention belongs to the technical field of microbial fertilizers, and in particular relates to an antibiotic scum microbial fertilizer and a preparation method thereof. Background technique [0002] Antibiotic residues are solid wastes produced during the production of antibiotics, and their main components are the mycelium of antibiotic-producing bacteria, unused medium, metabolites produced during fermentation, degradation products of the medium, and a small amount of antibiotics. Wait. The existing antibiotic residues mainly include tetracyclics, aminoglycosides, polypeptides, macrolides, antifungals, anti-tuberculosis, etc. Because they contain a lot of nutrients, the treatment method of antibiotic residues in the past is After drying, it can be used as feed or feed additive. Due to a small amount of antibiotics remaining in it, long-term consumption of animals will cause other problems such as drug resistance and zoonotic diseases. The coun...

Problems solved by technology

Due to the characteristics of large output, high moisture content, and high nutrient content, antibiotic residues can be safely landfilled directly, which occupies a large area and has high disposal costs, which is easy to cause waste of resources; incineration and pyrolysis need to be dried first or additionally Adding fuel, the operation cost is high, and it is easy to cause secondary pollution and lead to the residue of heavy metals and antibiotics; the anaerobic digestion system produces more pollutants, and the wastewater is difficult to treat; the aerobic composting method can realize the bacteria residue. Harmful treatment, and the development of special fertilizers to realize the recycling of fungal residues, but the application of this method has limitations in practice, it takes a long time, and it is not easy to control, and the existing aerobic composting technology has not completely degraded the fungal residues. antibiotics, and a small amount of antibiotic residues, which have a certain impact on the environment

[0005] Patent No. CN105457968B discloses a harmless treatment method for antibiotic residues, which inactivates antibiotic residues at a pH of 8-11 and a temperature of 90-100°C. During the treatment process, no waste gas, The treatment cost is low, and the treated bacteria residue can be reused reasonably, but some antibiotics have better thermal stability, such as gentamicin, etc., which cannot be completely inactivated under this condition, and there are antibiotic residues

At present, the preparation of fertilizers from antibiotic residues has been widely studied and applied at home and abroad, but except for the approval of penicillin residues for fertilizer production, there have been no reports of other antibiotic residues being legally used, and the main research directions Mainly use a single antibiotic residue to prepare fertilizers. Now a safe and effective method is needed to use one or several types of antibiotic residues to prepare fertilizers, which has achieved the complete removal of antibiotics in the residues and the effective use of nutrient organic matter in the residues
