Problems solved by technology

[0003] However, the research on the treatment and recycling technology of antibiotic residues in my country is still immature, and there is no safe and effective treatment method for antibiotic residues.
[0004] The patent application with publication number CN 105457968 A discloses a harmless treatment method for antibiotic residues, which is to adjust the pH value of antibiotic residues and then inactivate them. It is found through experiments that this method cannot make cephalosporin C bacteria residues and penicillin residues are completely inactivated, and the residual antibiotics will still pose a threat to the ecological environment and human health

Embodiment 1

[0029] Embodiment 1 fungus residue processing method of the present invention

[0030] Methods as below:

[0031] ①. Fresh cephalosporin C wet fungus residue 100m3 filtered by ceramic membrane in the cephalosporin extraction workshop has a solid content of 9.8%, residual cephalosporin potency of 841 μg / ml, and pH value of 3.5.

[0032] The cephalosporin residue is passed through a centrifugal pump at a rate of 40m 3 / h into the ammonia water mixer, while the concentration of 23% ammonia water in 0.5m 3 / h into the ammonia mixer, the mixed cephalosporin slag enters the buffer tank to continue mixing, and observes that the pH meter reading is 7.8.

[0033] 2. Enter the cephalosporin residue after adjusting the pH value in step ① into the moist heat sterilization system. The cephalosporin residue and the high-pressure steam with a pressure of 0.4 MPa are directly contacted and heated in the injector. After heating, the temperature of the cephalosporin residue is 136 ° C, and th...

Embodiment 2

[0038] Embodiment 2 fungus residue processing method of the present invention

[0039] Methods as below:

[0040] ①. 500m of fresh penicillin wet fungus residue filtered by the penicillin fermentation workshop 3 , the solid content was determined to be 10.1%, the residual penicillin titer was 498 μg / ml, and the pH value was 6.1. The penicillin residue is passed through a centrifugal pump at a rate of 50m 3 / h into the ammonia water mixer, while the concentration of 23% ammonia water in 0.5m 3 / h into the ammonia mixer, the mixed penicillin slag enters the buffer tank and continues to mix, observe the pH meter reading at 8.

[0041] ②. Enter the penicillin slag after adjusting the pH value in step ① into the moist heat sterilization system. The penicillin slag and the high-pressure steam with a pressure of 0.4MPa are directly contacted and heated in the injector. After heating, the temperature of the penicillin slag is 138°C, and then Entry volume is 10m 3 The maintenance ...

Abstract

The invention provides a method for preparation of an organic fertilizer from antibiotic bacterial residue. The method includes the steps of: a. taking antibiotic bacterial residue, and adjusting thepH value to 5.5-8; b. B, inactivating the bacteria residue: maintaining the pH adjusted bacterial residue obtained in step a at 130-140DEG C for 12min, thus obtaining the product. The invention also provides the prepared organic fertilizer. The method provided by the invention can completely remove antibiotic residual from the bacterial residue, and also has a low destruction degree on organic nutritional ingredients in the bacterial residue, and the prepared fertilizer is safe and has good efficacy. Moreover, the method has the advantages of simple process, easy operation, less energy consumption, and has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of reutilization of antibiotic scum resources, and in particular relates to a method for preparing organic fertilizer by using antibiotic scum. Background technique [0002] Antibiotic scum refers to the mycelium waste residue produced during the antibiotic fermentation production process, which belongs to industrial waste. The main components are mycelium, metabolites produced during the fermentation process, degradation products of the medium, residual organic solvents, and residual antibiotics. The antibiotic residues contained in the fungus residue will be enriched in the animal body, and enter the milk and eggs through lactation and egg production, and then cause toxic and side effects on humans, making pathogenic bacteria in the human body resistant to antibiotics. Therefore, how to effectively deal with antibiotic residues is not only the need to improve the economic benefits of enterprises, but also ...
